Description

Technical Field

[0001] This invention relates to the field of slipform control in concrete pouring, and more particularly to a method for tracking and controlling the slipform path in rectangular channel concrete pouring. Background Technology

[0002] In the field of slipform control for concrete pouring, existing solutions typically involve marking centerlines and edges and measuring the installation positions of guide rails based on design drawings. The guide rail baseline is established through the installation of channel steel guide rails and elevation correction with a level. This is followed by assembling steel formwork into a large overall formwork, adjusting supports and tie rods, reinforcing with tie rods and water-stop bolts, and setting up steel pipe supports and scissor braces. Then, layered symmetrical pouring, alternating pouring, and slipform displacement are performed. Finally, a laser level is used for leveling and marking, a level and transparent spirit level are used for horizontal monitoring, and the verticality of control points and plumb bobs is checked for verification. However, these solutions suffer from limitations such as poor coordination between guide rail allowable deviation records, formwork reinforcement records, slipform displacement records, and verticality test records; a disconnect between displacement and verification processes; and difficulty in standardizing recording methods. Existing methods largely rely on phased measurements and manual experience to organize processes. In the case of slipform displacement during concrete pouring in rectangular channels, issues arise such as inconsistencies in the reference of centerline and edge markings to guide rail installation positions, and a lack of stable transmission of data between laser leveling and subsequent horizontal and verticality checks. These issues make it difficult to meet the stable requirements for slipform path tracking control in rectangular channel concrete pouring. Regarding the joint processing of slipform displacement records and guide rail allowable deviation records, existing technologies generally have common shortcomings in record generation, association, and retrieval. This makes it difficult to establish a consistent process of measurement-correction-displacement-leveling-horizontal monitoring-verticality detection in the application scenario of slipform displacement during concrete pouring in rectangular channels. Consequently, the process data required for path tracking control is difficult to continuously trace and uniformly verify. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a method for tracking and controlling the slipform path during concrete pouring in rectangular channels, comprising: S100: Obtain design drawings, total station and level; mark center line and edge line and measure and lay out the guide rail installation position; perform channel steel guide rail installation and level elevation correction; generate guide rail allowable deviation record. S200. Based on the guide rail allowable deviation record, the steel formwork is assembled into a whole large formwork, and the support and tie rod are adjusted. The connection of the tie rod and water-stop screw is reinforced and the steel pipe support and scissor brace are set up, and the formwork reinforcement record is generated. S300. Based on the template reinforcement record, perform layered symmetrical casting, alternating casting, and slipform displacement processing to generate a slipform displacement record; the slipform displacement processing specifically includes: The slipform displacement handling includes a backtracking process based on alternating pouring records. When the records show that the alternating sequence is not closed or the re-inspection fails, the process is triggered to supplement the alternating pouring process. Preparations before relocation include visually inspecting for obstacles and signs of loose connections on the channel steel guide rail, as well as checking the connection status of the sliding formwork drive wheel, drive motor, electromagnetic brake, and wire rope. If any abnormalities are found, the process should be paused and cleaned or adjusted. The displacement is performed by controlling the drive motor to move the drive wheel along the channel steel guide rail via the control button. The electromagnetic brake is in a controllable braking state and actively brakes when the power is off. During the shift, monitoring is performed. When jamming, abnormal force, or electromagnetic brake malfunction occurs, emergency braking, shifting is paused, and on-site investigation is initiated. After shifting, locking and verification are performed to keep the electromagnetic brake in a braking state. Visual inspection is conducted to identify signs of slipform device displacement, and a slipform shifting record is generated. The slipform shifting record includes the shifting start state, braking trigger point, abnormal handling action, and termination state, and is associated with the alternating pouring record. S400. Based on the sliding mode displacement record and the guide rail allowable deviation record, perform laser leveling and marking, leveling and horizontal monitoring by a level and transparent level tube, and perform verticality detection of control points and plumb bob to generate a verticality detection record.

[0004] Furthermore, the process of marking the centerline and edge lines and measuring and setting out the guide rail installation position includes: The centerline and edgeline marking process includes using a total station to survey and mark the centerline and edgelines according to the design drawings. This marking process involves traceable on-site identification of the survey points and subsequent marking processing. The marking processing includes re-measurement, point verification, and anomaly rollback: when the total station observations and re-measurement values ​​are inconsistent, the station orientation, centering status, and target aiming are checked first; if necessary, orientation and re-measurement are repeated. If the re-measurement is still inconsistent, marking is paused and the measurement control points are verified. A level instrument participates in elevation readings during the same measurement period, recording elevation readings near the centerline and edgeline markings and associating them with the marking points. The guide rail installation position surveying process is performed, which includes reading and verifying the completeness of the centerline and edgeline markings; when marking points are missing or blurred, a rollback and supplementary measurement are triggered.

[0005] Furthermore, the process of installing the channel steel guide rails and correcting the level instrument elevation includes: The installation process for the channel steel guide rail includes segmenting and fixing the channel steel guide rail according to its installation position, and verifying the alignment. If there is a deviation, fine-tuning or rework is performed. The leveling instrument elevation correction process includes establishing a measuring station near the guide rail segment, taking elevation readings at key positions of the channel steel guide rail, adjusting them against the elevation requirements, and setting trigger conditions: when the difference between two consecutive elevation readings exceeds the limit, the instrument status is checked and the readings are taken again. A guide rail allowable deviation record is generated, which includes the correction results for flatness allowable deviation, spacing allowable deviation, and elevation allowable deviation, and is associated with the measurement time and measuring station conditions.

[0006] Furthermore, the process of assembling the steel formwork into a large, integrated formwork, and adjusting the supports and tie rods includes: The steel formwork assembly process for the overall large formwork includes reading and verifying the completeness and correspondence of the guide rail allowable deviation records. When a record is missing or an abnormal indication is detected, a retraction to the channel steel guide rail for retesting is triggered. Then, the assembly sequence is arranged according to the rectangular canal wall alignment. First, the steel formwork panels are pre-assembled and the joint fit and misalignment are checked. Then, secondary positioning and verification are performed on the slipform device to ensure that the formwork assembly fits the slipform device. The alignment is verified by comparing the center line and edge line marks with a total station. The support and tie rod adjustment process includes setting up supports and connecting them to the stress-bearing parts of the overall large formwork. The tightness is adjusted point by point and the allowable deviation of flatness is verified. After each round of adjustment, the panel condition is verified by using a string line, straightedge, or total station. When there are local high or low points, secondary adjustments are performed.

[0007] Furthermore, the process of reinforcing the tie rod connection with the water-stop screws and installing steel pipe supports and scissor braces includes: The reinforcement treatment of the tie rod connection includes installing tie rods at intervals of 50cm, using a zoned symmetrical tightening method, checking the plate surface condition after each round of tightening, and making minor adjustments to adjacent rods when local bulging or shrinkage occurs. The steel pipe support and scissor bracing setup includes laying out steel pipe supports and scissor bracing, setting and verifying the fixing status segment by segment, adjusting the position or fixing method when the support point is unstable, and verifying and adjusting the tightening degree when the formwork status rebounds, generating a formwork reinforcement record. The formwork reinforcement record includes the arrangement status of tie rods, the setting status of steel pipe supports and scissor bracing, and is associated with the formwork allowable deviation record and the overall large formwork.

[0008] Furthermore, the process of layered symmetrical casting includes: The layered symmetrical pouring process includes reading and verifying the integrity and closure status of the formwork reinforcement record. When a record is missing or the reinforcement status is loose, a reversal to re-tightening of the tie rods and re-jacking of the supports is triggered. Then, concrete is poured into the formwork in a layered symmetrical sequence, dividing the pouring into multiple continuous layers. Within each layer, the formwork is poured in a left-right symmetrical sequence, and the status changes of the tie rods, steel pipe supports, and scissor braces are observed. When local displacement or loosening occurs, the pouring is paused and re-tightening or re-jacking actions are performed. At the same time, the abnormality and handling actions are recorded. The layered symmetrical pouring process also includes construction rhythm constraint control. The triggering condition for entering the next layer is jointly determined by the completion status of the current layer's pouring and the stability status of the formwork system, generating a layered symmetrical pouring record.

[0009] Furthermore, the alternating pouring process includes: The alternating pouring process includes a layered symmetrical pouring record. When an unclosed anomaly is found in the record, a rollback to the corresponding layer is triggered for supplementary treatment. Then, an alternating position is selected, the alternating rhythm is controlled, and the position switching is triggered based on the current alternating position's mold entry completion status and template stability status. The alternating process is also checked, and the process is paused and addressed when the change in the state of the tie rod or support exceeds the limit.

[0010] Furthermore, the process of using a laser leveling instrument to mark levels and for leveling with a level instrument and transparent spirit level to monitor the level includes: The laser leveling and marking process includes reading the sliding formwork displacement record to confirm that the sliding formwork device has stopped and is locked. If it is not locked, a wait is triggered until the record is updated. The control point layout range is determined based on the guide rail elevation correction information in the guide rail allowable deviation record. The laser leveling instrument is deployed and self-checked to stabilize the reference light surface. Markings are made on the marking carrier surface to form control points. When the reference light surface vibrates or is obstructed, a pause in marking and adjustment is triggered, generating a control point marking record. This record includes the marking position, the laser leveling instrument deployment status, and association information with the sliding formwork displacement record and the guide rail allowable deviation record. Leveling and transparent level tube horizontal monitoring is performed. This monitoring includes triggering supplementary marking based on the control point marking record when a point is covered or erased. The leveling instrument and transparent level tube are deployed for benchmark verification: the first round of readings is taken for the control point markings, and the first round of benchmark records is generated.

[0011] Furthermore, the process of performing verticality checks on control points and plumb bobs includes: The control point and plumb line verticality detection process includes: based on horizontal monitoring records, supplementary monitoring is triggered when there are missing segments or abnormal unclosed sections in the records; stable monitoring periods in the horizontal monitoring records are selected as detection time points, plumb line suspension points are set up and the plumb line is stabilized, and waiting for stabilization is triggered when wind disturbance causes swaying; the plumb line is compared with the control point to observe the relative positional relationship, and the offset trend is judged in combination with the horizontal monitoring records; when the observation is obstructed, the detection is paused and obstructions are cleared.

[0012] Furthermore, the verticality measurement records include: The verticality test record includes the test time point, comparison conclusion, and correlation information with the horizontal monitoring record and the sliding formwork displacement record.

[0013] The key innovations of this invention include: (1) Based on the template reinforcement record, the process is organized in a fixed order of layered symmetrical casting, alternating casting and slip form displacement, and the process product of slip form displacement is solidified into slip form displacement record, so that the slip form displacement record becomes the pre-input object of the subsequent link.

[0014] (2) Based on the sliding form displacement record and the guide rail allowable deviation record, establish a continuous detection link for laser leveling instrument leveling and marking, level instrument and transparent level tube horizontal monitoring and control point and plumb line verticality detection, and solidify the link terminal as verticality detection record to realize the entry binding of the detection link with the sliding form displacement record and the guide rail allowable deviation record.

[0015] (3) During the operation of the laser leveling instrument for leveling and marking, the level instrument and the transparent level tube for horizontal monitoring, and the control point and the plumb line verticality detection, a record transmission relationship is formed around the control point, so that the detection activities take the control point as the unified object caliber, forming a traceability carrier consistent with the verticality detection record.

[0016] The following are its main beneficial effects: (1) By binding the operation link of layered symmetrical pouring, alternating pouring and slip form shifting with slip form shifting record, the process basis of slip form shifting of rectangular channel concrete pouring can be called later, avoiding the problem of discontinuous path tracking control basis caused by the separation of slip form shifting and subsequent verification in the existing scheme.

[0017] (2) By simultaneously referencing the sliding mode displacement record and the guide rail allowable deviation record when starting the detection link, the laser leveling instrument for leveling and marking, the level instrument and the transparent level tube for horizontal monitoring and control points and the plumb line verticality detection are coordinated under the same reference constraint, which alleviates the problem that the guide rail allowable deviation record and the detection results are difficult to correlate and the detection basis is difficult to unify in the existing scheme.

[0018] (3) By using the control point as the common object diameter for laser leveling instrument leveling, leveling instrument and transparent level tube horizontal monitoring, and control point and plumb line verticality detection, the detection process is continuously carried out around the same control point, reducing the problem of inconsistent verification links caused by the inconsistency of point reference and the drift of the measurement object diameter in the existing scheme.

[0019] (4) Under the slippage displacement of the concrete pouring of the rectangular channel, the verticality detection record is the terminal product of the detection link. The operation results of the laser leveling instrument for leveling and marking, the level instrument and transparent level tube for horizontal monitoring, and the verticality detection of the control point and the plumb line are recorded in a unified form to alleviate the problem of scattered results and difficulty in forming a verifiable process basis in the existing scheme.

[0020] (5) Based on the reference relationship between the guide rail allowable deviation record through the steel formwork assembly into a whole large formwork, support and tie rod adjustment, tie rod waterstop connection reinforcement and steel pipe support, scissor bracing setting and subsequent detection link, the formwork reinforcement record, slip form displacement record and verticality detection record form a consistent data reference chain under the same construction benchmark, which alleviates the common problem in the existing scheme that the recording standard is difficult to unify and affects the continuity of path tracking control. Attached Figure Description

[0021] Figure 1 This is a flowchart illustrating a method for tracking and controlling the slipform path of concrete pouring in a rectangular channel, as provided in an embodiment of this application. Detailed Implementation

[0022] Example 1: Refer to Figure 1 This is a flowchart illustrating a method for tracking and controlling the slipform path of concrete pouring in a rectangular channel, provided by an embodiment of the present invention. The process may include at least steps S100-S400: S100: Obtain design drawings, total station and level; mark center line and edge line and measure and lay out the guide rail installation position; perform channel steel guide rail installation and level elevation correction; generate guide rail allowable deviation record. S200. Based on the guide rail allowable deviation record, the steel formwork is assembled into a whole large formwork, and the support and tie rod are adjusted. The connection of the tie rod and water-stop screw is reinforced and the steel pipe support and scissor brace are set up, and the formwork reinforcement record is generated. S300. Based on the template reinforcement record, perform layered symmetrical casting, alternating casting, and slipform displacement processing to generate a slipform displacement record; S400. Based on the sliding mode displacement record and the guide rail allowable deviation record, perform laser leveling and marking, leveling and horizontal monitoring by a level and transparent level tube, and perform verticality detection of control points and plumb bob to generate a verticality detection record.

[0023] Step S100 includes at least steps S110-S130: S110. Obtain design drawings, total station and level, and perform centerline and edgeline surveying and marking to obtain centerline and edgeline markings. Specifically, the design drawings serve as the basis for surveying and setting out, and at least include the plan layout of the rectangular canal, the position of the walls, and their alignment relationships. The center line and edge lines are the alignment information in the design drawings used to express the axis and boundary of the rectangular canal. The total station is the main surveying and setting-out equipment, used to establish a station on the construction site and complete the observation of angles, distances, and coordinates. The level is an auxiliary surveying device related to elevation, used to complete elevation reading and transmission under the same measurement benchmark. During implementation, the total station is first set up and leveled. The leveling operation includes tripod deployment, instrument centering, and leveling screw adjustment to make the total station readable. Then, orientation and verification are performed according to the on-site measurement control points. After orientation, the center line and edge lines in the design drawings are converted into on-site executable surveying and setting-out instructions. During operation, the surveying and setting-out instructions are expressed as a combination of coordinates and directions of several surveying and setting-out points. The total station aims at each point according to the surveying and setting-out instructions and gives the landing point position on the ground or the completed foundation surface.

[0024] Furthermore, during the surveying and marking of centerlines and edge lines, the marking serves as a traceable on-site identifier for the surveying points. This marking can be achieved by drawing lines, ink lines, nailing markers, or making marks on relevant components of the template. The markers are connected to form the visual alignment of the centerline and edge lines. The marking process includes re-measurement of the surveying points, point verification, and anomaly reversal: when there is a discrepancy between the total station observation and the re-measurement value of the same surveying point, the station's orientation, centering status, and target aiming are checked first; if necessary, orientation and re-measurement are repeated. If the re-measurement is still inconsistent, subsequent marking is paused, and the measurement control points are verified. Surveying continues only after verification. The level instrument, used in this section, participates in the elevation readings during the same measurement period, recording elevation readings near the centerline and edge line markers. These elevation readings are linked to the marker points, allowing subsequent actions regarding guide rail installation and elevation correction to directly reference the same batch of surveying benchmarks.

[0025] Understandably, the centerline and edgeline surveying and marking process is not a one-time action, but can be executed in a rolling manner according to construction sections during operation: if the markings of the previous section become unreadable due to construction disturbance or changes in site conditions before the slipform is moved to the next section, a resurvey and remarking is triggered; if the difference between two consecutive re-measurements within the same section exceeds the allowable reading error range on site, a resurvey and remarking is also triggered. Thus, the output product of S110 is the centerline and edgeline markings. These centerline and edgeline markings are recorded and archived within the section and are called as inputs for the subsequent S120. When S120 performs the guide rail installation position surveying and marking process, it directly references the line and point information of the centerline and edgeline markings. At the same time, these centerline and edgeline markings provide a preliminary line position source for the positioning and verification of the guide rail installation position in the subsequent main steps.

[0026] S120. Based on the centerline edge markings, perform guide rail installation position measurement and layout to obtain the guide rail installation position; Specifically, the guide rail installation position is a combination of installation lines and points near the rectangular channel wall of the channel steel guide rail. This serves to define the planar position of the channel steel guide rail and provide an operational reference for subsequent installation and leveling instrument elevation correction. During implementation, the integrity of the centerline and edge line markings is first read and verified. Verification includes checking the continuity of the centerline markings, the readability of the edge line markings, and the stability of the marking points. If missing marking points, blurred marking lines, or covered markings are found, a regress to S110 is triggered for supplementary surveying and marking. Once the centerline and edge line markings are restored to usability, the guide rail installation position surveying process resumes. During the guide rail installation position surveying process, the total station completes the planar layout. Operationally, the station orientation and aiming procedures are still used to project the guide rail installation line and several guide rail installation points onto the site. The marking process then solidifies the guide rail installation line into a workable positioning line.

[0027] Furthermore, the guide rail installation position measurement and layout process not only provides the guide rail installation line position but also the relative relationship between the guide rail installation points. This relative relationship is expressed through the recording of point numbers and point spacing. During recording, each guide rail installation point is associated with its corresponding centerline or edge line mark, forming a traceable measurement and layout link. To adapt to the subsequent straight installation and connection of the channel steel guide rails, the measurement and layout process also includes straightness verification of the guide rail installation position: multiple guide rail installation points on the same guide rail installation line position are re-aligned. If the re-alignment shows that the points deviate from the same straight line trend, the deviated points are corrected and the marks are updated. After updating, re-alignment is performed again until the straightness requirements for on-site construction are met. This verification process also includes an abnormal rollback mechanism. When station conditions are limited, causing unstable re-alignment, the station is first replaced or the alignment target is adjusted. If the adjustment still fails to resolve the issue, the measurement is paused and the measurement control points are re-verified. The process continues only after the re-verification is successful.

[0028] Understandably, the surveying and setting out of the guide rail installation position can be performed according to the "surveying and setting out - marking - verification - confirmation" cycle in the engineering embodiment. In an operable field embodiment, after the rectangular channel foundation construction is completed and a continuous working surface is formed, the surveyors set up total station stations on the working surface, read the alignment relationship between the center line and the edge line of the rectangular channel according to the design drawings, first verify the center line and edge line markings, and then, starting from the center line and edge line markings, sequentially survey and set out the guide rail installation points and mark them one by one. After marking is completed, the guide rail installation position is re-aligned and verified along the guide rail installation line. After verification, the guide rail installation position of that section is handed over to the subsequent guide rail installation process. Therefore, the output of S120 is the guide rail installation position. The guide rail installation position is recorded within the segment and is called as the input of the subsequent S130. When S130 performs the channel steel guide rail installation and level instrument elevation correction, it directly uses the guide rail installation position to complete the guide rail positioning and correction. At the same time, the guide rail installation position and the center line edge mark form a connection, providing a line reference for the sliding formwork device assembly and template reinforcement in the subsequent main step S200, and providing the prerequisite for the guide rail positioning for the sliding formwork displacement related actions in the subsequent main step S300.

[0029] S130. Based on the guide rail installation position, perform channel steel guide rail installation and level instrument elevation correction processing to generate guide rail allowable deviation record; Specifically, the channel steel guide rail is a guide rail component installed along the guide rail installation position. Its installation process includes three consecutive stages: positioning the channel steel guide rail, connecting and fixing, and alignment verification. During implementation, the channel steel guide rail is transported to its designated position in sections. Initial positioning is performed according to the guide rail installation points, ensuring the centerline of the channel steel guide rail aligns with the guide rail installation alignment. Next, adjacent channel steel guide rail sections are connected and fixed using welding or bolting. After connection and fixing, the connection is visually inspected and its tightness checked. The tightness check confirms that there are no gaps or misalignments at the connection that could affect the continuity of the guide rail. Subsequently, a total station is used to verify the alignment of the positioned channel steel guide rail. During verification, the actual position of the channel steel guide rail is compared with the guide rail installation position. If a deviation is found, fine-tuning is performed without dismantling the overall structure, followed by verification. If fine-tuning still fails to meet the comparison requirements, rework is triggered. Rework includes loosening the connection and fixing, repositioning, and reconnecting and fixing.

[0030] Furthermore, the leveling instrument elevation correction process is used to verify and adjust the elevation of the channel steel guide rail, ensuring that the guide rail is in a usable state that meets the requirements for subsequent sliding formwork displacement. During implementation, a leveling instrument station is first established near the guide rail section and leveled. Elevation readings are taken at key locations on each channel steel guide rail section, such as the guide rail ends, connections, and middle control points. After reading, the readings are compared with the elevation requirements corresponding to the installation position of that guide rail section, and adjustments are made to any elevation deviations. Adjustments can be made through shim adjustments, support adjustments, or fine-tuning at the connections. This correction process is triggered by the following condition: when the difference between two consecutive elevation readings of the same guide rail section exceeds the allowable reading error range on site, the leveling status of the leveling instrument and the leveling rod reading method are checked first, and the readings are retaken after the check. If abnormal differences still exist after the retake, the elevation correction for that section is paused, and the station position and reading path are verified. Correction continues after the verification is passed. The calibration process also sets recording requirements, forming a closed record of each reading, each position adjustment, and the subsequent rereading, to avoid situations where the guide rail status cannot be traced later.

[0031] Understandably, when generating the guide rail allowable deviation record, the guide rail allowable deviation record is a set of records for the allowable deviations of guide rail flatness, guide rail spacing, and guide rail elevation. Each record set corresponds to the installation result of the same section of channel steel guide rail and is bound to the installation position of that section of guide rail. The record for the allowable deviation of guide rail flatness is obtained by comparing readings at different positions of the guide rail; the record for the allowable deviation of guide rail spacing is obtained by measuring and comparing the relative positions of the two guide rails; and the record for the allowable deviation of guide rail elevation is obtained by comparing level instrument readings with re-readings. The generation of the guide rail allowable deviation record not only records numerical values ​​but also records the measurement time, station conditions, number of checks, and correlation information of adjustment actions, enabling subsequent steps to directly reference this record to achieve traceable construction connections. In a feasible field embodiment, after the channel steel guide rail is installed, the surveyor reads the elevation point by point along the guide rail section and makes a rereading reading. The installer adjusts the support or shim according to the rereading reading. After the adjustment is completed, the reading is read again and the final reading is written into the guide rail allowable deviation record. At the same time, the total station verifies the guide rail alignment and writes the verification result into the guide rail allowable deviation record. After the record is completed, the guide rail allowable deviation record is handed over to the subsequent slipform device assembly and template reinforcement process as input basis. Therefore, the output of S130 is the guide rail allowable deviation record. The guide rail allowable deviation record is used as input in the subsequent designated step S210. After obtaining the steel template, sliding formwork device and the guide rail allowable deviation record, S210 performs the assembly of the steel template into a whole large template. At the same time, the guide rail allowable deviation record is referenced by the subsequent sliding formwork displacement-related actions in the cross-main step connection. It serves as the source of the pre-constraint for the guide rail state when the sliding formwork displacement record is formed in the subsequent main step S300. It also provides a reference for the guide rail state during the operation of the laser leveling instrument for leveling and marking, the leveling instrument and transparent level tube for horizontal monitoring, and the control point and plumb line verticality detection in the subsequent main step S400. In summary, the technical effects of this step are as follows: It integrates the centerline and edgeline markings with the guide rail installation position into the continuous processing link of channel steel guide rail installation and level instrument elevation correction. By recording the allowable deviation of the guide rail, it solidifies the verification and adjustment process of the guide rail status, so that subsequent steps related to steel formwork assembly and slipform displacement have traceable guide rail input basis, reducing repeated measurement and rework caused by unclear guide rail status.

[0032] Step S200 includes at least steps S210-S230: S210. Obtain the allowable deviation records of the steel template, slip form device and the guide rail, and assemble the steel template into an integral large template to obtain the integral large template. Specifically, the steel formwork is a formwork component used to form a rectangular channel wall, which includes at least formwork panels corresponding to the inner and outer forming surfaces, connecting parts for connecting adjacent formwork panels, and force-bearing parts that cooperate with supports and tie rods; the slipform device is a device that carries the steel formwork and slides along the channel steel guide rail, and it participates in the operation as a bearing foundation for assembly and positioning in this step; the guide rail allowable deviation record is a guide rail status record output by S130 and archived, and the guide rail allowable deviation record at least reflects the detection and correction results of the allowable deviation of the channel steel guide rail flatness, the allowable deviation of the guide rail spacing, and the allowable deviation of the guide rail elevation in the current construction section. At the start of this step, the allowable deviation record of the guide rail is read and verified. The verification includes checking the completeness of the record, whether the record corresponds to the channel steel guide rail of the current construction section, and whether there are any anomalies in the guide rail status shown in the record that require rework. If the verification finds missing records, inconsistencies between the corresponding sections, or that the guide rail status shown in the record cannot support subsequent assembly and positioning, a rollback process is triggered. The rollback process includes pausing the steel formwork assembly and requesting a re-execution of the channel steel guide rail re-measurement and level instrument elevation correction. This step is resumed only after the allowable deviation record of the guide rail is updated. This triggering logic establishes a direct constraint relationship between the starting point of the steel formwork assembly and the guide rail status, avoiding repeated adjustments to the subsequent sliding formwork displacement link due to unclear guide rail status when starting large formwork assembly.

[0033] Furthermore, when assembling steel formwork into a large, integrated formwork, the steel formwork is first arranged according to the alignment of the rectangular channel wall. In practice, this assembly sequence typically involves pre-assembling the formwork panels on the ground or work platform, followed by overall assembly and alignment near the installation position of the channel steel guide rails. Specifically, workers splice adjacent steel formwork panels, using the connecting parts to align and tighten them, creating a continuous shaped surface. During the alignment process, the fit of the panel joints and the misalignment of the edges must be checked simultaneously. If joints are not properly aligned or misalignment is significant, the corresponding connecting parts are loosened and re-aligned before tightening. If necessary, connectors are replaced or the assembly posture of the formwork panels is adjusted until the fit requirements for continued assembly on site are met. Subsequently, the pre-assembled template panels are repositioned on the slipform device. During the repositioning, the bearing points and positioning points of the slipform device are used as a reference to ensure that the overall template assembly fits snugly against the mounting surface of the slipform device. After fitting, the overall dimensions and symmetry of the template assembly are checked. The check can be performed by comparing the corresponding readings of the center line and edge line marks with a total station. If the check shows that the alignment of the template assembly deviates from the center line and edge line marks, the subsequent adjustment of the support and tie rods will not be carried out. Instead, the installation position of the template assembly on the slipform device will be fine-tuned and checked again. Only after the check is passed will the template assembly be considered as a usable overall template.

[0034] Understandably, the overall large template is the output product of this step, meaning a template assembly that has been assembled, installed on the slipform device, and possesses overall rigidity and a continuous forming surface. To ensure the overall large template is traceable and reliably usable in subsequent steps, this step records and archives its key assembly information after completion. This record includes at least the steel template assembly section, the tightness of the connecting parts, the correspondence between its installation position and the slipform device, and the association identifier with the guide rail allowable deviation record. The resulting overall large template is recorded as the output field name "Overall Large Template" within the segment and is subsequently used as input in S220. S220 performs support and tie rod adjustments based on the overall large template. Simultaneously, the overall large template and the guide rail allowable deviation record constitute the preconditions for the slipform displacement record in the subsequent main step S300, and form a consistent correspondence with the control point marking, horizontal monitoring, and verticality detection in the main step S400, ensuring that the detection objects before and after displacement can stably fall on the same assembly of the overall template and the slipform device.

[0035] S220. Based on the overall large template, perform support and tie rod adjustment processing to generate template allowable deviation record; Specifically, the support is a load-bearing and stabilizing component that cooperates with the overall large formwork. It is used to limit the relative displacement of the overall large formwork and maintain its spatial posture during the pouring and slipforming process. The tie rod is a tension component that cooperates with the overall large formwork. It is used to constrain the relative position between the inner and outer forming surfaces and participate in the formation of the overall force system. The input source for the support and tie rod adjustment process is the overall large formwork output by S210. The overall large formwork has been assembled and initially positioned on the slipforming device before entering this step. This step adjusts the support and tie rod to make the overall large formwork ready for subsequent formwork reinforcement and concrete pouring. At the beginning of this step, the assembly status of the overall large formwork is checked. The check includes checking whether there is looseness in the connection parts, whether there is obvious warping on the formwork surface, and whether there are local gaps in the fit with the slipforming device. If looseness in the connection parts or obvious local gaps are found, a pre-correction is triggered. The pre-correction includes re-tightening the connection parts and adjusting the fit. After the correction is completed, the support and tie rod adjustment process is entered.

[0036] Furthermore, the adjustment of supports and tie rods includes controlling the allowable deviations of flatness and verticality. These allowable deviations are the allowable deviation boundaries of the formwork state, and their correspondence with specific numerical requirements has been established in the previous scheme. During implementation, supports are first laid out to form a stable connection between the supports and the stress-bearing parts of the overall large formwork. After the supports are laid out, the tightness of the supports is adjusted. The adjustment process adopts a "point-by-point adjustment—verification—re-adjustment" rhythm: construction personnel adjust the tightness of each support point sequentially along the length of the formwork to ensure that there is no visible elastic rebound or local bulging of the formwork surface near each support point. After each round of adjustment, the surface state of the overall large formwork is verified. Verification can be done by using a string line, straightedge, or by comparing with total station measurement points. If the verification shows that there are local high or low points in a certain area, the corresponding support point in that area is returned for a second adjustment. After the second adjustment, verification is performed again until the area meets the conditions for continuing to adjust the tie rods. Tie rod adjustment is performed based on support adjustment. The focus of tie rod adjustment is on the relative position between the inner and outer forming surfaces and the verticality of the overall large template. In specific operation, tie rods are first installed according to the predetermined installation hole positions or connection points of the overall large template. Then, the tie rods are gradually tightened or loosened in groups according to the symmetrical relationship to make the spacing between the inner and outer forming surfaces uniform and match the design dimensions of the rectangular channel wall. When uneven local stress occurs during the tightening process, causing the template edge to twist, tightening is paused and reversed fine-tuning is performed in the symmetrical order of adjacent tie rods to eliminate the twisting trend before continuing. Trigger conditions are set in this process: when the verification shows that the verticality has a continuous deviation and cannot be converged by single-point tie rod adjustment, an overall verification is triggered. The overall verification includes checking whether the support tightness is consistent, checking whether there is local warping on the sliding formwork device mounting surface, and checking whether the guide rail status has changed in conjunction with the allowable deviation record of the guide rail. Tie rod adjustment is resumed after the abnormality is eliminated.

[0037] Understandably, the output of this step is a template allowable deviation record. This template allowable deviation record is a collection of records of the allowable flatness and verticality deviations of the entire large template after the support and tie rod adjustments are completed. During project implementation, it is formed through a closed loop of "checking readings—adjusting actions—checking confirmation," and is associated with the section identifiers of the entire large template, the slipform device identifiers, and the guide rail allowable deviation records. This allows subsequent template reinforcement, pouring, and relocation steps to trace the template's state. The generated template allowable deviation record is archived within the section under the output field name "Template Allowable Deviation Record" and is called as input for subsequent step S230. S230 performs reinforcement of the tie rod connection and steel pipe support and scissor bracing based on the template allowable deviation record. Simultaneously, this template allowable deviation record forms a before-and-after comparison with the verticality detection record of the main step S400 during cross-step transitions, enabling the detection and judgment during the relocation process to reference and verify the initial allowable deviation state of the template, avoiding isolated readings during relocation detection without a comparable template baseline.

[0038] S230. Based on the template allowable deviation record, perform reinforcement of the tie rod connection and steel pipe support and scissor bracing, and generate template reinforcement record; Specifically, the tie rods are reinforcing components that connect the inner and outer forming surfaces and participate in resisting lateral pressure. They also meet water-stopping requirements and are used to maintain the template spacing during the pouring stage. The steel pipe supports are supporting components that provide outer or inner support to the overall large template. The scissor braces are components used to form an oblique support system and limit lateral deformation. The input source for the reinforcement of the tie rods and the setting of the steel pipe supports and scissor braces is the template allowable deviation record output by S220. The template allowable deviation record is used in this step to guide the determination of the starting state of the reinforcement arrangement: when the template allowable deviation record shows that the overall large template has completed the adjustment of the supports and tie rods and is in a reinforceable state, reinforcement is initiated; when the template allowable deviation record is missing or shows that there is still a significant deviation trend, a rollback to S220 to readjust the supports and tie rods is triggered, and the process proceeds to this step only after the template allowable deviation record is updated. This triggering logic establishes a threshold relationship between the reinforcement action and the template allowable deviation state, avoiding the direct tightening of the tie rods when the template baseline is not stable, which would make subsequent correction difficult.

[0039] Furthermore, when reinforcing the tie rods with water-stopping connections, they are first installed according to a predetermined spacing. The spacing, as specified in the previous scheme, is one tie rod every 50cm. This spacing is one of the minimum sets of core parameters of this invention, used to limit the density of tie rods and match the stress state of the rectangular channel wall. In the implementation of the project, the construction personnel locate the installation holes or align the installation positions according to the spacing along the height and length of the template, and then insert and tighten the tie rods to form a stable connection between the inner and outer forming surfaces. The tightening process adopts a zoned symmetrical tightening method. First, the central area is initially tightened, and then the tightening is extended to both ends to avoid the tendency of the template to deflect due to tightening on one side first. After each round of tightening is completed, the entire large template is checked. The check includes the fit of the template surface, the condition of the joints, and the coordination of the supports and tie rods. If the check finds that a certain area has a local bulge or local shrinkage after tightening, the adjacent tie rods in that area are slightly loosened or tightened again and checked again until the area returns to a state where it can be further reinforced. Subsequently, steel pipe supports and scissor braces are installed. The steel pipe supports are installed with the support points reliably connected to the stress-bearing parts of the overall large formwork. The scissor braces are installed to form a stable triangular support relationship and limit lateral displacement. During the installation process, a step-by-step installation and verification process is adopted. When it is found that the support points cannot be reliably fixed to the on-site foundation in a certain section, the position of the support points is adjusted or an available fixing method is used to achieve fixation. After fixation is completed, the installation continues. When the installation of scissor braces causes a change in local stress, resulting in a rebound trend in the allowable deviation of the formwork, a verification is triggered and the tightness of the supports and scissor braces is adjusted back. After adjustment, a verification is performed again and the subsequent installation continues.

[0040] Understandably, this step provides a traceable reinforcement status output for subsequent concrete pouring and slipform relocation. Therefore, after completing the reinforcement of the tie rod connection and the installation of steel pipe supports and scissor braces, a formwork reinforcement record is generated. The formwork reinforcement record is a comprehensive record set of the tie rod arrangement status, steel pipe support installation status, and scissor brace installation status. This record set is linked with the formwork allowable deviation record, the overall large formwork, and the guide rail allowable deviation record, and is formed in the field through a closed loop of "arrangement position - tightening status - verification and confirmation - anomaly correction". In a specific embodiment, within a rectangular channel wall section, installers install and tighten tie rods one by one every 50cm. After each section is tightened, surveyors or quality inspectors check the condition of the formwork surface and record the check results in the formwork reinforcement record. Subsequently, installers lay steel pipe supports and set scissor braces along both sides of the formwork. After the setup is completed, the fixed state of the support points and the overall stability are checked. After the check is passed, the final state is incorporated into the formwork reinforcement record, forming an executable record that can be directly handed over to the pouring team. Therefore, the output of S230 is a template reinforcement record. The template reinforcement record is archived in the segment with the output field name "template reinforcement record" and is called as the input of the subsequent designated step S310. After obtaining the template reinforcement record and concrete, S310 performs layered symmetrical pouring. At the same time, the template reinforcement record forms a prerequisite relationship with the alternating pouring record and slipform displacement record of the main step S300 in the cross-main step connection, and provides the object premise of "template reinforcement status is fixed" for the horizontal monitoring record and verticality detection record of the main step S400, so that the detection and judgment during the displacement process can fall on the template system that has been reinforced.

[0041] The technical effects of this step can be summarized as follows: The allowable deviation record of the template is used as the entry threshold for the reinforcement of the tie rod connection and the setting of steel pipe support and scissor bracing. The density of the tie rods arranged every 50cm and the process of segment-by-segment verification are written into the template reinforcement record. This allows the template reinforcement status to be directly called by S310 and stably correspond to the subsequent displacement detection object, reducing repeated adjustments caused by the lack of traceability of status between the reinforcement process and the pouring and displacement processes.

[0042] Step S300 includes at least steps S310-S330: S310. Obtain the template reinforcement record and concrete, and perform layered symmetrical pouring to obtain the layered symmetrical pouring record; Specifically, the template reinforcement record is a reinforcement status record output by S230 and already archived. This record includes at least the reinforcement status of the tie rod connection, the steel pipe support setup status, and the scissor brace setup status, and corresponds to both the overall large template and the slipform device. The concrete is the pouring material for the rectangular channel wall, and in this step, it serves as the input material for the layered symmetrical pouring process. Before the layered symmetrical pouring process begins, the template reinforcement record is read and reviewed. The review includes verifying the correspondence between the record identifier and the current construction section, the completeness of the tie rod tightening status, and whether there are any missing items in the fixing status of the steel pipe support and scissor brace. If the review finds missing items in the template reinforcement record, an incomplete reinforcement status, or obvious signs of loosening, a rollback process is triggered. This rollback process includes pausing concrete pouring and reverting to the tie rod re-tightening, steel pipe support re-jacking, and scissor brace re-setting actions. The rollback action is also written into the appended content of the template reinforcement record. The layered symmetrical pouring process resumes only after the review is passed. This triggering logic establishes a direct threshold relationship between the pouring action and the formwork reinforcement status, avoiding repeated corrections in the subsequent sliding formwork displacement link caused by entering the pouring process when the formwork system is not stable.

[0043] Furthermore, the layered symmetrical pouring process employs a pouring sequence that matches the inner and outer forming surfaces of the rectangular channel wall. Construction workers pour concrete into the formwork within the template system supported by the slipform device, with the pouring position defined by the forming cavity of the overall large template. Layered symmetrical pouring refers to dividing the pouring process of the same construction section into multiple consecutive layers, completing the pouring within each layer in a left-right or bilaterally symmetrical sequence, ensuring that the lateral pressure changes on both sides of the template remain similar within the same time period. This operational characteristic does not introduce additional material terminology; it is directly composed of the three existing terms "layered," "symmetrical," and "pouring." In actual operation, the starting point for the first layer of pouring is first selected, typically located at one end of the construction section or near the junction of already formed sections. Then, concrete is distributed symmetrically into the formwork on both sides. After the pouring of one layer is completed, the next layer is poured. During the pouring process, it is necessary to continuously observe the stress state of the tie rod and the posture changes of the steel pipe support and scissor brace. When it is observed that the local support is displaced, the scissor brace node is loose, or the tie rod nut is retracted, the pouring process should be paused immediately and the tightening or jacking action should be performed. After the tightening or jacking is completed, the pouring process should be resumed. At the same time, the abnormality and the handling action should be included in the layered symmetrical pouring record to form a traceable process link.

[0044] Understandably, layered symmetrical pouring also involves constraining and controlling the construction rhythm. This constraint is reflected in the placement rhythm of the same layer and the entry conditions for the next layer. The triggering conditions for entering the next layer are typically determined on-site by jointly assessing the completion status of the current layer's placement and the stability of the formwork system. The completion status can be determined by observing the filling height and surface leveling of the forming cavity, while the stability of the formwork system can be determined by visual inspection and manual re-inspection of the tie rods, steel pipe supports, and scissor braces. If the triggering conditions are not met, the next layer is not entered; the current state is maintained, and supplementary placement or fine-tuning of the formwork system is performed. Once the triggering conditions are met, the next layer is entered, and the above symmetrical placement and anomaly handling process is repeated. This process forms a closed rhythm of "placement—review—handling—replacement," ensuring that the layered symmetrical pouring record fully reflects the placement sequence, anomaly trigger points, and handling actions for each layer.

[0045] In the engineering implementation example, for a section of rectangular channel wall construction, the construction team first confirmed, based on the formwork reinforcement records, that the tightness of each tie rod and the fixing status of the steel pipe supports and scissor braces were ready for pouring. Then, they organized the concrete pouring using conventional on-site methods. Following the requirement of symmetrical layered pouring, the team first completed partial pouring of the first layer on one side of the formwork, then moved to the symmetrical position on the other side to complete the same layer. They then returned to the vicinity of the starting point to fill in any deficiencies in that layer, completing the first layer's closure before moving to the next layer. After each layer was completed, on-site personnel re-inspected the tie rod nuts and support nodes. Only after passing the re-inspection could they proceed to the next layer. If the re-inspection revealed a loose nut or insufficiently tightened support, pouring was paused and re-tightened or re-supported before resuming. All the order of the mold layers, the re-inspection conclusions, and the handling actions are written into the layered symmetrical casting record. The layered symmetrical casting record is archived within the segment as the output field name of this step, and is called as input in the subsequent S320. S320 performs alternating casting processing based on the layered symmetrical casting record. At the same time, the layered symmetrical casting record provides the preliminary process basis for the sliding formwork displacement processing in S330 in the cross-main step connection, and forms a consistent object link in the same segment with the control point marking, horizontal monitoring, and verticality detection of the subsequent main step S400.

[0046] S320. Based on the layered symmetrical pouring record, perform alternating pouring processing to generate an alternating pouring record; Specifically, the layered symmetrical pouring record is a process record output from S310 and already archived. The alternating pouring process is carried out based on this record. Alternating pouring refers to switching between different formwork entry positions in a predetermined alternating sequence within the same construction section, so that continuous formwork entry is not concentrated on the same side or the same part, thereby making the stress change of the formwork system more uniform. This alternating sequence can be determined on site in conjunction with the layered symmetrical pouring record and must match the status of the tie rods, steel pipe supports, and scissor braces. At the beginning of this step, the layered symmetrical pouring record is read. The read content includes at least the formwork entry sequence of each layer, the abnormal handling nodes of each layer, and the re-inspection conclusions when each layer is completed. When the read finds an unclosed abnormal handling or a failed re-inspection mark in a certain layer, a rollback process is triggered. The rollback process includes returning to the corresponding layer for supplementary re-inspection or supplementary handling. The alternating pouring process will only begin after the layered symmetrical pouring record is updated to an alternating pouring state. This triggering mechanism ensures that alternating pouring is not an isolated action, but rather is carried out on the basis of the closed-loop layered symmetrical pouring record, thus making the preconditions for subsequent slipform displacement clearer.

[0047] Furthermore, the alternating pouring process is operationally manifested as a continuous chain of "alternating position selection—alternating cycle control—alternating process verification—abnormal handling and archiving." Alternating position selection is determined on-site within the formwork forming cavity, typically around the length of the rectangular channel wall and the two forming surfaces. Alternating positions satisfy the principle of discontinuous concentration between adjacent positions and switching between left and right sides. Alternating cycle control is reflected in the entry conditions for each alternating position switch. Entry conditions include at least the completion status of the current alternating position's formwork and the stability of the formwork system. The completion status can be determined by observing the filling height and surface condition of the current alternating position, while the stability of the formwork system can be determined by re-inspecting the tie rods, steel pipe supports, and scissor braces. When the entry conditions are not met, alternating position switching is not performed; the current alternating position is maintained, and additional formwork is added or a re-inspection is conducted. The alternation process is reviewed throughout the alternation rhythm control. After each alternation position switch is completed, the on-site personnel compare and check the formwork status of the two alternation positions before and after the switch. The check includes whether the tightness of the tie rods has changed, whether the tightness of the steel pipe support has changed, and whether the scissor brace nodes have become loose. If the changes are found to be beyond the acceptable range on site, the alternation pouring is paused and re-tightened, re-supported, or re-set. After the handling is completed, the alternation pouring is resumed. At the same time, the trigger point, handling action, and re-inspection conclusion are written into the alternation pouring record.

[0048] Understandably, the alternating pouring process needs to be linked to the entry conditions for slipform displacement. Therefore, this step records the "alternating pouring completion status" during operation. The alternating pouring completion status includes at least the closure of the alternating sequence, the re-inspection conclusion of the last alternating position entry, and a description of whether the formwork system is in a state where slipform displacement can be initiated. This status description does not introduce new terminology and uses existing expressions such as "re-inspection," "handling," and "recording," and maintains an archiving method consistent with the formwork reinforcement record. The alternating pouring record is the output of this step. The record is formed by continuously writing the time sequence of each alternating position switch, the re-inspection conclusion before and after the switch, the abnormal trigger point, and the handling action into the same record carrier, and establishing an association identifier with the layered symmetrical pouring record so that the two types of records can be jointly called in subsequent steps. In the engineering embodiment, the same quality inspector can follow and re-inspect the alternating pouring process on site and record it in real time. After the construction team completes the entry into the formwork according to the alternating sequence, the quality inspector re-inspects the tie rods and support nodes. After the re-inspection is passed, the completion status of the alternating pouring record is signed and archived.

[0049] Therefore, the output of S320 is an alternating pouring record. The alternating pouring record is archived within the segment as an output field name and is called as input in the subsequent S330. S330 performs slipform displacement processing based on the alternating pouring record. At the same time, the alternating pouring record forms a continuous link in the same segment with the control point marking record, horizontal monitoring record, and verticality detection record of the main step S400 in the cross-main step connection, so that the detection object after slipform displacement can be traced back to the completion state of alternating pouring, thereby making the "pouring-displacement-detection" process more tightly closed.

[0050] S330. Based on the alternating pouring record, perform sliding formwork displacement processing to generate a sliding formwork displacement record; Specifically, the alternating pouring record is a process record output by S320 and archived, and the sliding formwork displacement process is carried out based on this record. The sliding formwork displacement is the process of the sliding formwork device moving along the channel steel guide rail. The sliding formwork device carries the overall large template and forms a guiding relationship with the channel steel guide rail. The sliding formwork displacement process needs to maintain a consistent object link with the guide rail allowable deviation record and the template reinforcement record, but the direct input of this step is the alternating pouring record because the entry condition for sliding formwork displacement needs to be triggered by the alternating pouring completion status. At the beginning of this step, the alternating pouring record is read and the alternating pouring completion status is identified. When the alternating pouring record shows that the alternating sequence is not closed, the re-inspection has failed, or there are still unresolved abnormalities, a rollback process is triggered. The rollback process includes returning to the alternating pouring process to perform supplementary mold entry, supplementary re-inspection, or supplementary handling actions until the alternating pouring record is updated to a displaceable state before entering the sliding formwork displacement process. This triggering mechanism makes the sliding formwork displacement independent of experience-based judgment, but rather constrained by the closed state of the alternating pouring records, thus making it easier for the subsequent S400 inspection process to form a stable closed loop.

[0051] Furthermore, the sliding formwork relocation process comprises four continuous action links: "pre-relocation preparation—relocation execution—in-relocation monitoring—post-relocation locking and recording," with each action corresponding to an existing terminology object. Pre-relocation preparation includes visual inspection of the channel steel guide rail and component status inspection of the sliding formwork device. The visual inspection focuses on whether there are obvious obstacles on the channel steel guide rail and whether there are signs of looseness in the connections. The component status inspection focuses on the connection status of the drive wheel, drive motor, electromagnetic brake, and wire rope. When the inspection reveals obstacles on the channel steel guide rail or loose connections, the relocation is paused, and the obstacles are cleared or tightened before resuming. When the inspection reveals that the electromagnetic brake is in an abnormal state or that the wire rope connection is abnormal, the relocation is paused, and adjustments or replacements are made before resuming. After preparations for relocation are completed, the relocation process begins. During relocation, on-site personnel control the drive motor via control buttons, which drives the drive wheels to move the sliding formwork along the track. During relocation, the electromagnetic brake remains in a controllable braking state. In the event of a power outage, the electromagnetic brake activates, stopping the sliding formwork at its current position. Relocation continues only after power is restored or the situation is resolved. This operating method ensures the relocation process is interruptible and resumable, and it avoids introducing new terminology, using only existing component terminology such as drive wheels, drive motor, electromagnetic brake, wire rope, and control buttons.

[0052] Monitoring is conducted throughout the relocation process. Monitoring includes at least checking the smoothness of the sliding formwork, the presence of any jamming on the travel track, the abnormal stress on the wire rope, and any abnormal heating or noise from the electromagnetic brake. If jamming or abnormal stress is detected, an emergency brake is triggered, pausing the relocation. The emergency brake stops the drive motor via a control button and engages the electromagnetic brake, followed by on-site troubleshooting. Troubleshooting includes checking for obstacles on the travel track, the contact between the drive wheels and the travel track, and the connection between the wire rope and the hook. After the troubleshooting is completed, if the abnormality is resolved, the brake is released and relocation resumes; if the abnormality persists, the brake is maintained and further action is taken until the conditions for resumption are met. The locking and recording process after displacement occurs after the sliding formwork reaches the predetermined position. The locking action is completed by maintaining the braking state with an electromagnetic brake. At the same time, the relative position of the sliding formwork and the channel steel guide rail is checked. The check includes visual judgment of whether there are obvious signs of displacement or torsion of the sliding formwork and verification of the correspondence with the center line and edge line marks. This check does not replace the subsequent laser leveling instrument leveling and marking, level monitoring with a level instrument and transparent level tube, and verticality detection of control points and plumb bobs in S410–S430. Instead, it serves as a pre-check for entering the main inspection step after displacement, so that the subsequent inspection has clearer entry conditions.

[0053] Understandably, the slipform displacement record is the output of this step. The slipform displacement record includes at least the displacement start state, braking trigger points during displacement execution, abnormal trigger points monitored during displacement, troubleshooting and handling actions, displacement termination state, and locking state, and is associated with the alternating pouring record. The slipform displacement record is generated by continuously writing the pre-displacement inspection conclusions, displacement execution control actions, monitored trigger events during displacement, and post-displacement locking verification conclusions into the same record carrier, and retaining the correspondence with the alternating pouring record in the record, so that subsequent testing steps can directly call this record to locate the testing point. In the engineering implementation, after completing the alternating pouring and forming an alternating pouring record, the construction personnel check the connection status of the drive wheel, drive motor, electromagnetic brake, and wire rope before relocation. Then, they drive the slipform device along the channel steel guide rail to the next construction position through the control button. If jamming occurs during the relocation, the drive motor is immediately stopped and the electromagnetic brake is triggered. After checking for obstacles on the walking track, the relocation is resumed. After the relocation is completed, the electromagnetic brake is maintained and the relocation is verified. Finally, the entire process is written into the slipform relocation record and archived.

[0054] Therefore, the output product of S330 is a sliding form displacement record. The sliding form displacement record is archived within the segment as an output field name and is called by the subsequent specified step S410 "obtain the sliding form displacement record and the guide rail allowable deviation record". At the same time, it serves as the detection link entry record of the main step S400 in the cross-main step connection, so that the subsequent control point marking record, horizontal monitoring record and verticality detection record can form a closed link in the same segment.

[0055] In summary, the technical effects of this step are as follows: the entry conditions for slipform displacement are bound to the closed state of the alternating casting record, and the braking trigger and recording of the electromagnetic brake are introduced during the slipform displacement process, so that the slipform displacement record can be directly referenced by subsequent detection steps, reducing the disconnect between displacement and detection and lowering the probability of omission in abnormal handling.

[0056] Step S400 includes at least steps S410-S430: S410. Obtain the sliding mode displacement record and the guide rail allowable deviation record, perform laser leveling and marking processing to obtain the control point marking record; Specifically, the sliding formwork displacement record is a process record output and archived by S330, which at least reflects the start and stop status of the sliding formwork device on the channel steel guide rail, the braking and locking status of the electromagnetic brake, the abnormal triggering and handling actions during displacement, and the review conclusion after the displacement is terminated; the guide rail allowable deviation record is an allowable deviation record output and archived by S130, which at least reflects the correction and acceptance information of the allowable deviation of the flatness of the channel steel guide rail, the allowable deviation of the guide rail spacing and the allowable deviation of the guide rail elevation, and forms a corresponding relationship with the center line edge mark and the guide rail installation position. At the beginning of this step, the sliding formwork displacement record is read to confirm that the sliding formwork device is in a stopped state and has completed braking and locking. If the sliding formwork device is still in a moving state or the braking and locking state has not been formed, a waiting process is triggered and the updated content of the sliding formwork displacement record is continuously read until the record reflects that the stopping and locking conditions are met before the laser leveling instrument leveling and marking process is started. This triggering condition establishes a sequential threshold relationship between the leveling and marking process and the sliding formwork displacement process, avoiding the distortion of records caused by conducting measurements before the sliding formwork device is stable.

[0057] Furthermore, the laser leveling instrument is a commonly used leveling device on site. Its working principle involves emitting a horizontal reference surface and forming a stable reference within the visible range. The leveling and marking process revolves around this horizontal reference. During implementation, the operator places the laser leveling instrument on a stable ground or support surface near the rectangular channel construction section and uses the equipment's self-check process to ensure the reference surface enters a stable output state. This self-check process is inherent to the equipment and does not introduce new process terminology. Subsequently, based on the guide rail elevation correction information in the guide rail allowable deviation record, the control point layout range for this leveling and marking is determined. The control point layout range covers the corresponding area of ​​the slipform device and the channel steel guide rail, and also takes into account the upper openings or accessible measuring points of the templates on both sides of the rectangular channel wall. These control points are the points used for subsequent horizontal monitoring and verticality testing. Within the process of this invention, they serve as a "verifiable and traceable" measurement reference on-site, without introducing additional abstract concepts.

[0058] During the leveling and marking process, the marking carrier surface is first selected. This carrier surface can be a visible surface on the slipform device, an accessible edge of the overall large formwork, or a fixed reference surface adjacent to the channel steel guide rail. The selection principle is that the points should be sustainable and not significantly disturbed by short-term pouring operations. Subsequently, when the reference light surface of the laser leveling instrument is projected onto the marking carrier surface, the operator marks the corresponding positions along the reference light surface to form control point markings. Multiple control point markings can be formed at multiple locations within the same construction section, thus ensuring coverage for subsequent horizontal monitoring. For each marking, the correlation information between the marking position and the slipform displacement record must be simultaneously written onto the recording carrier. For example, this includes "the displacement termination status corresponding to this slipform displacement record" and "the guide rail elevation correction information corresponding to this guide rail allowable deviation record," enabling the control point marking records to trace back to the displacement action and the guide rail correction action. If the reference light surface is found to be shaking, intermittent, or obstructed during the marking process, the marking will be paused and the laser leveler will be readjusted or the obstruction will be removed. Marking will continue after the reference light surface has stabilized. This abnormality handling will also be recorded in the control point marking record so that the record contains the complete operation process.

[0059] Understandably, the control point marking record is the output of this step, which includes at least a textual description of the laser leveling instrument's deployment status, the stable state of the leveling reference, the location of the control point markings, and related information with the sliding formwork displacement record and the guide rail allowable deviation record. In an engineering embodiment, after a sliding formwork displacement is completed on-site and locked by the electromagnetic brake, the surveyor reads the sliding formwork displacement record to confirm the locking is successful. At the same time, the guide rail allowable deviation record is retrieved to confirm the guide rail elevation correction information for the current construction section. Subsequently, the laser leveling instrument is deployed at a stable position beside the rectangular channel, and leveling points are marked on the upper opening of the sliding formwork device and the reference surface adjacent to the channel steel guide rail, forming multiple control point markings. Finally, the formation time, location description, and related records of each control point marking are written into the control point marking record and archived. Therefore, the output field of S410 is named Control Point Marking Record. This Control Point Marking Record is called as the input "based on the Control Point Marking Record" in the subsequent designated step S420. At the same time, this record, together with the preceding sliding mode displacement record, constitutes the detection link entry in the cross-main step connection, so that subsequent horizontal monitoring and verticality detection can be carried out along the same object link.

[0060] S420. Based on the control point marking records, perform level monitoring processing using a level instrument and a transparent level tube to generate a level monitoring record. Specifically, the control point marking record is a marking process record output and archived by S410, which clarifies the location and formation conditions of the control points, ensuring a consistent source of measurement points for subsequent monitoring. When this step is initiated, the control point marking record is first read to confirm that the control points have been formed and are identifiable. If the reading reveals that the control points have been covered by pouring operations, wiped off by vibration operations, or obstructed by site debris, supplementary marking processing is triggered, and the process returns to the laser leveling instrument's leveling and marking procedure to supplement the affected points. Horizontal monitoring processing only resumes after the control point markings are fully restored, ensuring that horizontal monitoring is always based on valid points.

[0061] Furthermore, the level instrument serves as the on-site elevation verification device, while the transparent level tube is a commonly used tool for comparing water levels on-site. The combination of these two instruments is used for continuous monitoring of the horizontal status of control points. During implementation, surveyors position the level instrument in a location that covers the control point area. After leveling the instrument, they verify the readings of each control point individually. The object of the reading verification is the elevation difference between the control point and the level instrument's line-of-sight reference. During this verification process, the level instrument readings are recorded as real-time on-site monitoring data. The transparent level tube, used in conjunction with the level instrument, is typically placed near the sliding formwork or template at an easily observable location. The water level line within the transparent level tube can be used to quickly compare the elevation change trends of different points. When continuous tracking with the level instrument is inconvenient, the transparent level tube can be used for supplementary monitoring. This deployment method is a standard on-site procedure and does not introduce additional terminology.

[0062] During the horizontal monitoring operation, the horizontal monitoring process follows a continuous chain of "benchmark verification—process tracking—anomaly triggering—verification archiving". In the benchmark verification stage, the level instrument is used to mark control points and generate the first round of benchmark records. A correspondence is established between the first round of benchmark records and the control point marking records, recording the association information between "corresponding to a certain control point marking" and "corresponding to a certain slipform displacement record". The process tracking stage is integrated throughout subsequent pouring operations and on-site waiting intervals. Surveyors use the level instrument to re-measure key control points at a predetermined frequency, while simultaneously using a transparent level tube to observe water level changes and compare the differences between the two ends of the water level. When the transparent level tube shows a significant change in the water level difference or a sudden change occurs in the level instrument's re-measurement reading, anomaly triggering is activated. The anomaly trigger handling includes checking the on-site status. The check should include at least whether the sliding formwork device's brake lock status is still maintained, whether there is any external impact near the channel steel guide rail, and whether there are any signs of loosening of the tie rods, water-stop bolts, steel pipe supports, and scissor braces. After the check, if the brake lock status is found to have changed, the process returns to the sliding formwork displacement handling link to relock and update the sliding formwork displacement record. Then, the level instrument re-measurement is performed, and the anomaly trigger and handling results are written into the level monitoring record. If no change in the brake lock status is found, the layout status of the transparent level tube and the level instrument is checked. For example, it is checked whether the transparent level tube is squeezed and deformed, whether there is any water leakage causing reading drift, and whether the level instrument has been displaced. After the check is completed, the process tracking continues.

[0063] Understandably, the horizontal monitoring record is the output of this step, which includes at least the initial reference reading of the level instrument, the readings of each subsequent re-measurement, the observation results of the transparent level tube, the abnormal trigger points and verification and handling actions, and forms a one-to-one point mapping relationship with the control point marking records. The horizontal monitoring record is generated by writing each level instrument reading and the observation results of the transparent level tube into the same recording medium in chronological order, while retaining the association fields with the control point marking records. The association fields include the location description of the control point marking and the corresponding sliding formwork displacement record identifier. In the engineering embodiment, after completing the leveling and marking, the surveyor first uses the level instrument to mark the first round of readings for each control point and writes them into the horizontal monitoring record as a reference. Then, during the subsequent pouring intervals and displacement preparation stages, the key points are re-measured at a fixed frequency, and the difference between the water level lines on both sides is compared through the transparent level tube. Once a change in difference is found, the locking status of the electromagnetic brake and the status of the support system are immediately checked, and the check process is written into the horizontal monitoring record. Therefore, the output field of S420 is named Horizontal Monitoring Record. This Horizontal Monitoring Record is called as the input "based on the Horizontal Monitoring Record" in the subsequent designated step S430. At the same time, this record, together with the control point marking record and the sliding form displacement record, forms a closed evidence chain of "post-displacement monitoring" in the cross-main step connection, so that the subsequent verticality detection can be carried out under the same measuring point system.

[0064] S430. Based on the horizontal monitoring record, perform verticality detection processing of the control point position and the plumb line to generate a verticality detection record; Specifically, the horizontal monitoring record is a monitoring process record output and archived by S420. It reflects the changes in the horizontal state of the control points during the monitoring period and includes information on abnormal triggering and handling actions. At the beginning of this step, the horizontal monitoring record is read and its validity is reviewed. The review includes whether the level instrument readings form a continuous record, whether there are obvious abnormalities in the transparent level tube observation, and whether the abnormal trigger points have been checked and handled. When the review finds that there are missing segments or unclosed segments in the horizontal monitoring record, supplementary monitoring is triggered and the process returns to the level instrument and transparent level tube horizontal monitoring flow for supplementary measurement. After the horizontal monitoring record is updated to a continuous and usable state, the verticality detection process is then initiated, thus ensuring that the verticality detection is carried out on a stable horizontal monitoring basis.

[0065] Furthermore, the verticality detection process revolves around control points and a plumb bob. The plumb bob is a tool used on-site for vertical reference comparison; it forms a stable plumb line through gravity. The control points are the points formed in S410 and monitored in S420. This step introduces the plumb bob at the control points to establish a vertical reference relationship. During implementation, the verticality detection time point is first selected based on the "monitoring period in a stable state" in the horizontal monitoring record. A stable state can be characterized by a recording segment where the level instrument reading changes gradually and there are no significant abrupt changes in the water level difference in the transparent horizontal pipe. Selecting this time point is a trigger condition and does not introduce new terminology. Subsequently, plumb bob suspension points are set up at the center and axis positions corresponding to the control points. These suspension points can be located at accessible fixed parts of the sliding formwork device or template system. The requirement is that the suspension points remain fixed and unaffected by external forces during the detection period. If wind disturbance or personnel movement causes the plumb bob to swing, a stabilization process is triggered, and the plumb line position is read again after the swing weakens.

[0066] During the verticality testing process, the testing personnel compare the plumb line with the control points. Specifically, this comparison involves observing the relative positional relationship between the plumb line projection and the marked control points, and combining this with the point status in the horizontal monitoring record to determine if there is any deviation trend. This judgment process does not introduce additional judgment terminology and still uses the terms "test" and "record." After the comparison is completed, the results are written into the verticality testing record. The verticality testing record must include at least the testing time, a description of the corresponding control point, a reference to the corresponding horizontal monitoring record time period, and the observation conclusions from the plumb line comparison. If, during the comparison process, the plumb line is found to be continuously swinging and unstable, or if new pouring or tamping near the control point obstructs observation, the testing is suspended and on-site handling actions are taken. These actions include suspending nearby work, clearing obstructions, or reselecting the testing time. After the handling is completed, the testing resumes, and the reason for the suspension and the handling actions are incorporated into the verticality testing record, ensuring the record contains the complete operational sequence.

[0067] Understandably, the verticality test record is the output of this step, forming a traceable test loop with the horizontal monitoring record and control point marking record within the same construction section. The verticality test record is generated by writing each control point comparison with the plumb bob into the record carrier in chronological order, while retaining the association information with the horizontal monitoring record. This association information includes at least the "referenced level reading period" and the "referenced transparent level tube observation period," and also retains the association information with the slipform displacement record, enabling the test results to be traced back to the corresponding displacement action. In the engineering embodiment, after completing one slipform displacement and forming a control point marking record, the surveyor continuously generates horizontal monitoring records. When the monitoring record shows that the point status is stable, the surveyor suspends the plumb bob at the center and axis positions and conducts verticality tests against the control points, writing the comparison conclusion and the referenced horizontal monitoring period into the verticality test record. If the plumb bob swings significantly during the test, the nearby work is paused and the comparison is resumed only after the plumb bob stabilizes; the entire pause and resumption process is also written into the verticality test record. Therefore, the output field of S430 is named Verticality Detection Record. This verticality detection record can be used in subsequent runs of the same construction section when the next slipform relocation process of S330 is carried out for pre-relocation verification. It can also be read as reference data before the next execution of the laser leveling instrument leveling and marking process of S410, so that the evidence chain of the process of "relocation - leveling and marking - horizontal monitoring - verticality detection" remains consistent during the cyclic execution.

[0068] In summary, the technical effects of this step are as follows: the control point marking records and horizontal monitoring records serve as the triggering and comparison bases for verticality testing, and the large plumb line comparison process records are transformed into verticality testing records. This enables the detection actions after relocation to have repeatable timing selection and abnormal handling archiving paths, thereby reducing the omissions and chain breaks caused by relying on experience and verbal handover in on-site measurements.
