Description

Technical Field

[0001] This invention relates to the field of slipform construction monitoring technology, and in particular to a construction method for a slipform trolley for a pumped storage power station shaft. Background Technology

[0002] The vertical shaft of a pumped storage power station is a key core structure of the power station's water conveyance and power generation system. Its construction accuracy directly affects the overall operational safety and stability of the power station. The construction of the vertical shaft slipform trolley is the core process that determines the quality of the vertical shaft structure and the construction efficiency.

[0003] Traditional construction methods have significant shortcomings: they lack a unified and precise three-dimensional coordinate positioning system, rely on manual experience for formwork arrangement, and are prone to radial offset, circumferential misalignment, and vertical elevation deviation; there is no systematic slip-lift sequence planning, the slip-lift time has no corresponding relationship with the changes in formwork coordinates, the construction process is disordered and untraceable; and there is a lack of dynamic monitoring and precise correction mechanisms, deviations are only discovered after they accumulate, which can easily lead to formwork deformation, substandard shaft structure, increased rework costs, and the risk of project delays.

[0004] To address this, the present invention proposes a construction method for a slipform trolley for the vertical shaft of a pumped storage power station. By establishing a three-dimensional coordinate matrix for the vertical shaft slipform, constructing a slipform timing system, implementing dynamic monitoring of construction and grouping and correcting jack deviations, the method achieves precise positioning, full-process control, and timely correction of deviations during slipform construction, thus ensuring the quality and efficiency of vertical shaft construction. Summary of the Invention

[0005] Technical problems to be solved: Template layout relies on manual experience, which can easily lead to problems such as radial offset, circumferential misalignment, and vertical elevation deviation.

[0006] To address the shortcomings of existing technologies, this invention provides a construction method for a slipform trolley for the vertical shaft of a pumped storage power station, thereby solving the technical problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A construction method for a slipform trolley for a pumped storage power station shaft includes the following steps:

[0009] S1. Establish a three-dimensional coordinate matrix for the vertical shaft sliding formwork. By defining a unified three-dimensional coordinate system, the precise position of the template in the vertical shaft space is determined.

[0010] S2. Construct a slipform timing system, taking the construction time sequence as the axis and each slipform movement as a point, establish the movement timing trajectory of the formwork during the construction process, and determine the coordinate changes of the formwork during the slipform process at each time sequence based on the movement timing trajectory.

[0011] S3. Construction dynamic monitoring: Determine the maximum allowable values ​​of four core deviations: center offset, verticality deviation, slip height deviation, and formwork coordinate deviation. Calculate the actual deviation based on coordinate changes during the slip process, compare the deviation with the preset value, and then locate the deviation problem.

[0012] S4. Slipform deviation correction: By controlling the lifting amount, lifting speed or start-stop sequence of jacks at different positions, the deviation is gradually corrected to the allowable range by utilizing the rigid linkage characteristics of the template.

[0013] In one possible implementation, the three-dimensional coordinate system in S1 has the design center of the shaft as the origin of the three-dimensional coordinate system, the X-axis is the permanent control pile in the power plant area along the radial direction of the shaft; the Y-axis is perpendicular to the X-axis, and the positive direction is clockwise along the shaft; the Z-axis is along the vertical direction of the shaft, with the design elevation of the shaft opening as ±0.00m, and is used to mark the elevation position of the components.

[0014] The X-coordinate of the template center point is the radial distance from the template center point to the center of the shaft design circle. The Y-coordinate of the template center point is The Z-coordinate of the template center point is .

[0015] In one possible implementation, the establishment of the movement time-series trajectory in S2 specifically includes:

[0016] Construction phase division: If the entire construction requires m slipway operations, then the process is divided into m phases. , ... One stage corresponds to one slide;

[0017] Determine the timing of slipforming: Based on the construction schedule and actual site conditions, determine the start time for each slipforming operation. Forming a time series , ... ;

[0018] Using time series as the axis and each slipform movement as a point, the movement sequence of the formwork during construction is established, and at each time point... The template slides from its current position to the next position, forming a movement time point; by connecting all the movement time points, the movement time trajectory of the template throughout the entire construction process can be obtained.

[0019] In one possible implementation, coordinate establishment during the template slip process in S2 includes:

[0020] New circumferential angle New X coordinate New Y coordinate New Z coordinate At each moving time point;

[0021] After each slip section, record the new coordinates of the template center point. Then the new coordinates As the initial coordinates for the next slip, that is: Repeat the above steps until all slip operations are completed.

[0022] In one possible implementation, the template deviation determination in S3 specifically includes:

[0023] Center offset: ,like This is determined to be a center offset deviation;

[0024] Verticality deviation: ,like This is determined to be a verticality deviation;

[0025] Glide height deviation: ,like This was determined to be a deviation in lift height;

[0026] Template coordinate deviation: and ,like or This was determined to be a template coordinate deviation.

[0027] In one possible implementation, the slip correction in S4 specifically includes:

[0028] The center offset deviation means that the center of the template deviates from the design center of the shaft. For the jack group in the opposite direction of the offset direction, the lifting stroke of a single slide is increased; for the jack group in the same direction of the offset direction, the lifting stroke of a single slide is reduced; while the jacks in other directions maintain the standard lifting stroke to ensure that the template is only offset and corrected in the direction of the center.

[0029] Verticality deviation is the circumferential angle of the template. If the deviation exceeds the tolerance, first use monitoring data to find the circumferential segment and the direction of the deviation that exceed the verticality tolerance. Then divide the jacks into circumferential segments. For the segment group with the deviation in the opposite direction, increase the lifting speed of the jacks; for the segment group with the deviation in the same direction, decrease the lifting speed of the jacks; and keep the other segment groups at the standard speed. By using the speed difference, the circumferential angle of the template is gradually corrected.

[0030] Slip-up height deviation is divided into single slip-up height deviation and overall elevation offset. (The text then discusses single slip-up height deviation.) If the slipforming height is insufficient, the single lift of all jacks will be increased by the corresponding amount during the next slipforming operation to make up for the deviation in one go; if the slipforming height is excessive, the single lift of all jacks will be reduced by the corresponding amount during the next slipforming operation to offset the deviation; for single slipforming height deviation, the lift of the local jack group with the deviation will be increased only during the next slipforming operation, while the other groups will maintain the standard lift, until the overall elevation is consistent with the design.

[0031] Template coordinate deviation is divided into radial problems with X-axis deviation and circumferential problems with Y-axis deviation. If only the X-axis is out of tolerance, the jacks in the negative X-axis direction are raised more and in the positive X-axis direction are raised less to correct the radial position. If only the Y-axis is out of tolerance, the circumferential segmented jacks corresponding to the positive Y-axis direction are accelerated and decelerated in the negative Y-axis direction to correct the circumferential position. If both the X and Y axes are out of tolerance, the above two adjustments are performed simultaneously.

[0032] Beneficial effects compared to existing technologies:

[0033] 1. In this scheme, a three-dimensional coordinate matrix is ​​established with the design center of the shaft as the origin, and the X-axis (radial towards the permanent control pile), Y-axis (circumferential clockwise), and Z-axis (vertical with the shaft opening as ±0.00m) are clearly defined. Combined with parameters such as the template height and shaft diameter, the X, Y, and Z coordinates of each template are accurately calculated. This achieves precise positioning of the template in the radial, circumferential, and vertical directions within the shaft space, solving the problems of ambiguous template arrangement and easy misalignment in traditional construction. It lays a precise spatial benchmark for slipform construction, ensures that the shaft structure outline matches the design height, and avoids structural hazards caused by positioning deviations.

[0034] 2. In this scheme, a slipform construction sequence system is constructed by dividing the construction into stages according to the number of slipform operations and determining the time point of each slipform operation based on the progress and site conditions. The formwork coordinates are dynamically updated in conjunction with the slipform height and radial / circumferential adjustment amounts. Then, targeted adjustments to the jack lift or speed are made in groups to correct deviations, achieving full controllability of the "time-position" process in slipform construction. Compared to traditional disordered slipform operations, this method makes each slipform operation traceable and controllable, reducing delays caused by blind operations and improving construction efficiency and process stability.

[0035] 3. In this solution, by establishing preset rules for deviations in center offset, verticality, slipform height, and formwork coordinates, the actual coordinate changes are compared with preset values ​​to identify the type of deviation. Then, precise correction is achieved through grouped adjustment of jacks, realizing dynamic monitoring of construction and early intervention for deviations. This avoids the problem of deviations accumulating only after they have occurred in traditional construction, effectively preventing risks such as formwork deformation and substandard shaft structures, reducing rework costs, ensuring stable construction quality, and lowering the probability of safety accidents caused by deviations.

[0036] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Figure 1 This is a flowchart of the method steps of the present invention. Detailed Implementation

[0038] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below.

[0039] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0040] Example:

[0041] Please refer to Figure 1 As shown in the figure, this embodiment introduces a construction method for a slipform trolley for a pumped storage power station shaft, including the following steps:

[0042] S1. Establish a three-dimensional coordinate matrix for the vertical shaft sliding formwork. By defining a unified three-dimensional coordinate system, the precise position of the template in the vertical shaft space is determined.

[0043] S1.1 Definition of coordinate system origin and grid: The origin of the three-dimensional coordinate system is taken as the center of the vertical shaft design circle, where:

[0044] The X-axis points radially towards the permanent control piles in the power plant area along the shaft; the Y-axis is perpendicular to the X-axis, with the positive direction being clockwise along the shaft, and is used to define the circumferential positions of components such as climbing poles and formwork; the Z-axis runs vertically along the shaft, with the design elevation of the shaft opening as ±0.00m, and is used to mark the elevation positions of components.

[0045] S1.2 Template coordinate definition: Taking the center position of the template as the punctuation point, the coordinates of each template are determined by the template height, the diameter of the shaft, and the number of templates under a specific perimeter of the shaft, as detailed below:

[0046] Determine the X coordinate of the template center point:

[0047] Calculate the radial distance from the center point of the template to the center of the shaft design circle, i.e., the X-coordinate of the template center point. Assume the template height is H, the shaft diameter is D, and the template's radial offset along the shaft is... ( (where the radial distance from the center point of the template to the center of the shaft design circle is), then the X-coordinate of the center point of the template is: ;

[0048] Determine the Y-coordinate of the template center point:

[0049] Based on the number of templates required for the vertical shaft, the shaft perimeter is divided equally, and the circumferential position of each template is determined. Assuming the shaft perimeter is C and the number of templates is n, the circumferential spacing of each template is C / n. Starting from the center point of the first template, the center points of each template are determined sequentially in a clockwise direction. Assuming the circumferential angle of the center point of the i-th template is... (Taking the positive X-axis as the starting direction and clockwise as the positive direction), the Y-coordinate of the template center point is: ;

[0050] Determine the Z-coordinate of the template center point:

[0051] Based on the height of the template and the elevation distribution of the shaft, determine the elevation position of the template center point; assuming the template height is H, the shaft elevation range extends downwards from the design elevation at the shaft opening (±0.00m), and the template is located on the k-th layer of the shaft (counting downwards from the shaft opening), then the Z-coordinate of the template center point is: (Assume that the height of each template is equal and the center point of the template is located at the midpoint of the template height).

[0052] S2, Constructing the Slip-up Timing System

[0053] S2.1 Using the construction time sequence as the axis and each formwork slip section as the point, establish the movement time sequence trajectory of the formwork during the construction process;

[0054] Division of construction time sequence:

[0055] The entire construction process is divided into several construction stages according to time sequence. Each stage corresponds to one formwork slip-up operation, meaning the entire construction process requires m formwork slip-up operations. Therefore, the construction time sequence can be divided into m stages, denoted as follows: , , ... .

[0056] Determining the timing of template slipforming:

[0057] Based on the construction schedule and actual construction conditions, the specific time points for each formwork slip section are determined. Let the time point for the i-th formwork slip section be . Then a time series can be obtained: , , ... ,in Indicates the first The start time of the secondary template slide.

[0058] Establishment of the shift sequence:

[0059] Using time series as the axis and each slipform movement as a point, the movement sequence of the formwork during construction is established, and at each time point... The template slides from its current position to the next position, forming a movement time point; by connecting all the movement time points, the movement time trajectory of the template throughout the entire construction process can be obtained.

[0060] S2.2. Based on the movement timeline trajectory in S2.1, determine the coordinate changes of the template during the slipforming process at each timeline.

[0061] During each template slipforming process, the coordinate change of the template center point needs to be calculated based on the slipforming height, radial adjustment amount, and circumferential adjustment amount, as detailed below:

[0062] Assume that the template lift height is at the i-th lift. Radial adjustment amount is The circumferential adjustment amount is ,but:

[0063] New circumferential angle ,in, It is the first Circumferential angle after the second slip;

[0064] New X coordinate ,in The initial X coordinate;

[0065] Calculate the new Y coordinate ,in The initial Y coordinate;

[0066] Calculate the new Z coordinate ,in It is the first Z-coordinate after the second slip;

[0067] At each moving time point Record the coordinate changes of the template center point and update the template's coordinate information; that is, first, record the new coordinates of the template center point after each slide. Then the new coordinates As the initial coordinates for the next slip, that is: Repeat the above steps until all slip operations are completed.

[0068] S3. Construction dynamic monitoring: By comparing the actual coordinate changes over time with pre-established preset rules, it is possible to determine whether any deviations occur during the slipforming process.

[0069] S3.1 Establish preset rules

[0070] Center offset preset rules: Define the maximum allowed center offset. That is, the maximum allowable radial deviation from the center point of the template to the design center of the shaft;

[0071] Perpendicularity Deviation Preset Rules: Define the maximum perpendicularity deviation allowed. This refers to the maximum permissible angular deviation of the template in the circumferential direction;

[0072] Preset rules for slip zone height deviation: Define the maximum allowable slip zone height deviation This refers to the maximum permissible deviation in the height of each lift.

[0073] Template coordinate deviation preset rules: Define the maximum allowable template coordinate deviation and This refers to the maximum permissible deviation of the template center point in the X and Y axis directions.

[0074] S3.2 Compare the actual coordinate changes under time series with the preset values.

[0075] Center offset comparison: By calculating the actual center offset ,judge Does it exceed the preset maximum center offset? ;

[0076] Verticality deviation comparison: By calculating the actual verticality deviation ,judge Does it exceed the preset maximum verticality deviation? ;

[0077] Comparison of actual slip height deviation: By calculating the actual slip height deviation ,judge Does it exceed the preset maximum slip height deviation? ;

[0078] Template coordinate deviation comparison: By calculating the actual template coordinate deviation and ;judge and Do they exceed the preset maximum template coordinate deviation? and .

[0079] S3.3 Analysis of Slip-up Deviation Types

[0080] if If so, it is determined to be a deviation of the center of the circle;

[0081] if If so, it is judged as a verticality deviation;

[0082] if If so, it is determined to be a deviation in slip height;

[0083] if or If so, it is determined to be a template coordinate deviation.

[0084] S4. Slip-up deviation correction: The core logic of jack correction for solving four types of deviations is "targeted group adjustment". Specifically, by controlling the lifting amount, lifting speed or start-stop sequence of jacks at different positions, the deviation is gradually corrected to the allowable range by utilizing the rigid linkage characteristics of the template.

[0085] S4.1, Center Offset Deviation: The essence of center offset is that the center of the formwork deviates from the design center of the shaft. It is necessary to pull the formwork back to the center by using the difference in lifting stroke—more lifting in the opposite direction and less lifting in the same direction—specifically:

[0086] Positioning offset direction: The offset direction is determined by monitoring data, such as the template center offset towards the positive X-axis direction and the negative Y-axis direction;

[0087] Adjust the lifting stroke in groups: For jack groups in the opposite direction of the offset direction (such as symmetrical groups in the negative X-axis direction and positive Y-axis direction), increase the lifting stroke of a single slide; for jack groups in the same direction of the offset direction (such as symmetrical groups in the positive X-axis direction and negative Y-axis direction), reduce the lifting stroke of a single slide; while jacks in other directions maintain the standard lifting stroke to ensure that the template is only offset and corrected in the direction of the center.

[0088] Dynamic verification: After each adjustment of the slipform, remeasure the coordinates of the template center. If the deviation decreases, continue adjusting by the same amount until the deviation decreases. Then restore all jacks to their standard lifting position;

[0089] It is important to note that the lift adjustment should be done in small steps multiple times to avoid excessive adjustment in a single step, which could cause template deformation. At the same time, it is necessary to ensure that the symmetrical jacks are adjusted synchronously to prevent new verticality deviations.

[0090] S4.2, Verticality deviation, the verticality deviation is the circumferential angle of the template. If the deviation exceeds the tolerance (e.g., a section of the template is excessively skewed clockwise), the circumferential attitude of the template needs to be adjusted by using a speed difference: "increasing the speed of the segmented jacks in the opposite direction of the deviation and decreasing the speed of the segmented jacks in the same direction." Specifically:

[0091] Determine the deviation segment and direction: Find the circumferential segment (such as 1 / 4 of the shaft circumference) where the verticality exceeds the tolerance by monitoring data and the direction of deviation (such as clockwise deviation).

[0092] Adjusting speed by grouping: Divide the jacks into 4-8 segments along the circumferential direction (e.g., each segment corresponds to 90° or 45°). For segments with deviations in the opposite direction (e.g., the corresponding segment in the counterclockwise direction), increase the lifting speed of the jacks; for segments with deviations in the same direction (e.g., the out-of-tolerance segment in the clockwise direction), decrease the lifting speed of the jacks; otherwise, maintain the standard speed for the remaining segments, and use the speed difference to gradually correct the circumferential angle of the template.

[0093] Real-time angle monitoring: The circumferential angle is remeasured every 1m of elevation gain (or one construction stage). , if the deviation Immediately restore all jacks to standard speed;

[0094] It is important to note that the speed adjustment must be linked to the slip height to avoid excessive speed in some areas, which could lead to grout leakage at the formwork joints. In addition, if the deviation is large, it can be combined with "pausing the jacks for 1-2 cycles in some areas" (such as pausing the slip section jacks once in the out-of-tolerance section) to enhance the correction effect.

[0095] S4.3, Slip-up height deviation. Slip-up height deviation is divided into two categories: single slip-up height exceeding the tolerance and overall elevation deviation. It needs to be directly calibrated through "supplementary lift / reduction lift", specifically:

[0096] For insufficient / excessive lift in a single lift ( (Out of tolerance): If the current slip height is insufficient, the single lift of all jacks will be increased by the corresponding amount during the next slip, making up for the deviation in one go; if the current slip height is excessive, the single lift of all jacks will be reduced by the corresponding amount during the next slip, offsetting the deviation.

[0097] For overall elevation deviation: locate the local jack group with elevation deviation, increase the lift of only the jack group during the next slipforming, and keep the standard lift of the other groups until the overall elevation is consistent with the design.

[0098] It should be noted that the supplementary lifting / reduction lifting is only for one slip-up cycle to avoid multiple accumulations leading to new deviations. If the deviation is >5cm, it needs to be supplemented / reduced in 2 to 3 times to prevent the template from being deformed by tension.

[0099] S4.4 Template coordinate deviation: Template coordinate deviation (X or Y axis out of tolerance) is a "detailed manifestation" of center offset and perpendicularity deviation (e.g., X-axis out of tolerance is mostly a radial problem, Y-axis out of tolerance is mostly a circumferential problem). It is necessary to combine the first two methods and adjust the jacks in the corresponding directions accordingly. Specifically:

[0100] Determine the type of coordinate deviation:

[0101] If only the X-axis is out of tolerance (e.g.) (2cm larger than the design value) Adjust according to the "center offset deviation" method: raise the jack more in the negative direction of the X-axis and less in the positive direction to correct the radial position;

[0102] If only the Y-axis is out of tolerance (e.g.) (2cm smaller than the design value) Adjust according to the "verticality deviation" method: increase the speed of the circumferential segmented jacks in the positive direction of the Y-axis and decrease the speed in the negative direction to correct the circumferential position;

[0103] If both the X and Y axes are out of tolerance, perform the above two adjustments simultaneously, but reduce the adjustment amplitude each time to avoid mutual interference.

[0104] Step-by-step coordinate verification: After each adjustment of the slip ratio, simultaneously measure the X and Y axis coordinates until both are consistent. Then restore the jack to its normal parameters;

[0105] It is important to note that when adjusting in multiple directions simultaneously, the axis with the larger deviation should be corrected first. After adjustment, the template joints should be checked for flatness to prevent local misalignment caused by coordinate correction.

[0106] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

4. The construction method of a slipform trolley for a pumped storage power station shaft as described in claim 1, characterized in that, S4 slip correction specifically includes: The center offset deviation means that the center of the template deviates from the design center of the shaft. For the jack group in the opposite direction of the offset direction, the lifting stroke of a single slide is increased; for the jack group in the same direction of the offset direction, the lifting stroke of a single slide is reduced; while the jacks in other directions maintain the standard lifting stroke to ensure that the template is only offset and corrected in the direction of the center. Verticality deviation is the circumferential angle of the template. If the deviation exceeds the tolerance, first use monitoring data to find the circumferential segment and the direction of the deviation that exceed the verticality tolerance. Then divide the jacks into circumferential segments. For the segment group with the deviation in the opposite direction, increase the lifting speed of the jacks; for the segment group with the deviation in the same direction, decrease the lifting speed of the jacks; and keep the other segment groups at the standard speed. By using the speed difference, the circumferential angle of the template is gradually corrected. Slip-up height deviation is divided into single slip-up height deviation and overall elevation offset. (The text then discusses single slip-up height deviation.) If the slipforming height is insufficient, the single lift of all jacks will be increased by the corresponding amount during the next slipforming operation to make up for the deviation in one go; if the slipforming height is excessive, the single lift of all jacks should be reduced by the corresponding amount during the next slipforming operation to offset the deviation; for single slipforming height exceeding the tolerance, the lift of the local jack group with the deviation in elevation will be increased only for that group of jacks during the next slipforming operation, while the other groups will maintain the standard lift, until the overall elevation is consistent with the design. Template coordinate deviation is divided into radial problems with X-axis deviation and circumferential problems with Y-axis deviation. If only the X-axis is out of tolerance, the jacks in the negative X-axis direction are raised more and in the positive X-axis direction are raised less to correct the radial position. If only the Y-axis is out of tolerance, the circumferential segmented jacks corresponding to the positive Y-axis direction are accelerated and decelerated in the negative Y-axis direction to correct the circumferential position. If both the X and Y axes are out of tolerance, the above two adjustments are performed simultaneously.
