Description

Technical Field

[0001] This invention relates to the field of civil engineering construction control technology, specifically to a method for collecting and controlling construction parameters of polymer composite stabilized soil beam yard base. Background Technology

[0002] In the field of civil engineering, load-bearing structures such as site slabs, road base courses, and beam yard foundations typically require processes like mixing, shaping, compaction, and curing to form a base structure that meets load-bearing and elevation requirements. For beam yards used in precast beam production, the base course not only bears construction loads from beam fabrication platforms, beam transport channels, and beam storage areas, but is also affected by machinery movement, material stacking, periodic compaction, and environmental changes. With the application of polymer composite stabilized soil materials in beam yard base courses, base course construction no longer relies solely on traditional soil compaction control. It also requires combining the spraying of composite stabilizers, initial compaction, leveling, and re-compaction processes, and collecting and judging data on elevation, spraying intervals, residual changes, and construction wave disturbances. Therefore, the collection and control of base course construction parameters in polymer composite stabilized soil beam yards has gradually become an important aspect of construction quality control.

[0003] Current methods for collecting and controlling base course construction parameters mainly rely on manual measurement, single elevation verification, compaction pass recording, or judgment based on construction experience. These methods typically only focus on whether the elevation after re-rolling meets design requirements, making it difficult to simultaneously track elevation residual changes across multiple construction phases, including initial rolling, leveling, and re-rolling. For polymer composite stabilized soil beam yard base courses, residual fluctuations formed during the initial rolling stage may be temporarily masked after leveling or reappear after re-rolling; shaping deviations formed during leveling may be mixed with wave undulations after re-rolling; and the spraying time interval between the end of composite stabilizer spraying and the end of re-rolling may also affect the mixing, compaction, and shaping state of the stabilized soil. If judgment is based solely on elevation data from a single phase or a single construction parameter, it is difficult to distinguish whether the source of anomalies is shaping residuals, compaction recurrence, spraying time interval, or the stabilization process. Furthermore, the construction parameter control path is prone to repeated adjustments based on field experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for collecting and controlling construction parameters of polymer composite stabilized soil beam yard base courses, thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for collecting and controlling construction parameters of polymer composite stabilized soil beam yard base course, comprising: The construction unit is divided and a sequence of measuring points is generated. The reference parameters, time phase height program sequence and spraying time distance of each measuring point are extracted from the construction record and a loose paving reference height program sequence is generated. The time phase height program sequence in the loose paving reference height program sequence is calculated to generate a three-time phase residual sequence. Multi-scale band reconstruction of the three-phase residual sequence yields the initial rolling construction band sequence, the leveling construction band sequence, and the re-rolling construction band sequence. The returned phase value, returned energy value, and time distance correlation value are constructed, and the order is compared and the order decision is performed to generate the returned principal factor. A control point sequence was constructed based on the rolling construction band sequence, and the control path of construction parameters was determined together with the return principal factor. Based on the construction parameter control path, the current construction unit is controlled and the post-control re-rolling height program sequence is obtained. The post-control re-rolling height program sequence is used to perform residual calculation to generate the post-control re-rolling residual sequence. The post-control three-phase residual sequence is then assembled and iterated to generate the post-control return principal factor to execute the base construction parameter control.

[0006] Preferably, the base area between two adjacent side piles is defined as the longitudinal range of the construction unit along the base construction direction. Within the current longitudinal range, the construction center line is used as the lateral positioning reference, and the left and right side lines are used as the lateral boundaries to enclose and form a construction unit. A unique construction unit number is assigned to each construction unit. Using the edge stake measuring points, construction centerline measuring points, and measuring points on both sides of the construction edgeline within the construction unit as the source of measuring points, the measuring points are sorted according to the ascending order of mileage coordinates. The measuring points with the same mileage coordinates are sorted according to the direction from one side of the construction edgeline to the other side of the construction edgeline based on the cross-sectional coordinates, thus forming a measuring point sequence. Based on the API interface, the construction parameters of each measuring point are extracted from the construction records, including the reference parameters, the time phase height program sequence, and the injection time distance; Construction records include surveying and setting out records, composite stabilizer spraying records, initial rolling surveying records, leveling surveying records, and re-rolling surveying records; Extract the edge pile elevation, design longitudinal slope, design transverse slope, and loose paving thickness from the survey and layout records to form benchmark parameters; Extract the post-roughing elevation from the initial rolling measurement records of the current construction unit, and generate a post-roughing elevation sequence by arranging the measuring points. Extract the leveling elevation from the leveling measurement records of the current construction unit, and generate a leveling elevation sequence by arranging the measurement points. Extract the post-re-rolling elevation from the re-rolling measurement records of the current construction unit, and generate a post-re-rolling elevation sequence by arranging the measurement points; The high-speed sequence after initial rolling, the high-speed sequence after leveling, and the high-speed sequence after re-rolling constitute the phase high-speed sequence; Extract the end time of composite stabilizer spraying from the composite stabilizer spraying record of the current construction unit, extract the end time of re-rolling from the re-rolling measurement record of the current construction unit, and generate the spraying pressure time interval based on the time interval between the end time of composite stabilizer spraying and the end time of re-rolling.

[0007] Preferably, the edge pile elevation, design longitudinal slope and design transverse slope are used as input data. The RANSAC robust fitting technology is used to fit the measuring point sequence to generate a compaction benchmark elevation sequence. The loose paving thickness is matched with the measuring point sequence to form a loose paving correction sequence. Then, the compaction benchmark elevation of each measuring point in the compaction benchmark elevation sequence is superimposed with the loose paving correction value of the same measuring point in the loose paving correction sequence to generate a loose paving benchmark elevation sequence. Using the loose-laying benchmark high program series as the deduction benchmark, the high program series after initial rolling, the high program series after leveling, and the high program series after re-rolling are subjected to difference processing to generate the initial rolling residual sequence, the leveling residual sequence, and the re-rolling residual sequence. Based on the construction phase sequence of initial rolling, leveling, and re-rolling, a three-phase residual sequence is formed.

[0008] Preferably, the residual sequences of the initial rolling, leveling, and re-rolling are decomposed into multiple scales using discrete wavelet transform to obtain wavelet decomposition components. Then, the spatial wavelength range represented by each wavelet decomposition component is statistically analyzed based on the distance between adjacent measuring points in the measuring point sequence. Combined with the working width, travel speed, and sampling interval of the construction equipment in the initial rolling, leveling, and re-rolling processes, the construction disturbance band range of each process is obtained. Wavelet decomposition components whose spatial wavelength range falls within the construction disturbance band range are selected for reconstruction to generate the initial rolling construction band sequence, leveling construction band sequence, and re-rolling construction band sequence, respectively. A sequence slip set is defined, and normalized cross-correlation is performed on the initial rolling construction band sequence, the leveling construction band sequence, and the re-rolling construction band sequence based on the sequence slip set to obtain the return phase value; wherein, the sequence slip set consists of integer slip values, each integer slip value representing the number of measuring points that a construction band sequence moves relative to another construction band sequence along the construction unit measuring point sequence.

[0009] Preferably, the energy value of the leveling construction band is generated by summing the squares of the residual values ​​of the leveling construction band at each measuring point in the leveling construction band sequence, and the energy value of the rolling construction band is generated by summing the squares of the residual values ​​of the rolling construction band at each measuring point in the rolling construction band sequence. The energy values ​​of the leveling construction band and the rolling construction band are arranged in descending order of value, and the position of the rolling construction band energy value in the arrangement result is recorded as the return energy value. Among them, the residual value of the leveling construction band is the value of the leveling residual sequence after reconstruction within the construction disturbance band range at the current measuring point; the residual value of the re-rolling construction band is the value of the re-rolling residual sequence after reconstruction within the construction disturbance band range at the current measuring point. The current construction unit and the construction units that have obtained the return energy value before the current construction unit are sorted according to the construction sequence to form a construction unit time-distance energy queue. The injection time distance and return energy value in the construction unit time-distance energy queue are dimensionless to form an injection time distance sequence and a return energy reference sequence. The return energy sequence is used as the reference sequence and the injection time distance sequence is used as the comparison sequence. The grey relational coefficient of the current construction unit is calculated according to the grey relational coefficient algorithm. The grey relational coefficient under the current construction unit number is read and recorded as the time-distance relational value.

[0010] Preferably, the return principal factor is generated based on the return phase value, return energy value, and time-distance correlation value; When the peak value of the initial complex cross-correlation is in the first order in the arrangement results, the phase main cause is marked as the compaction return main cause; when the peak value of the initial scraping cross-correlation is in the first order in the arrangement results, the phase main cause is marked as the shaping residual main cause; when the peak value of the scraping complex cross-correlation is in the first order in the arrangement results, the phase main cause is marked as the stable forming main cause. When the energy value of the rolling construction band is in the first position in the arrangement results, the main energy cause is marked as the main cause of compaction recurrence; when the energy value of the leveling construction band is in the first position in the arrangement results, the main energy cause is marked as the main cause of shaping residual. When the grey relational coefficient of a construction unit is in the first position in the construction unit time-distance energy queue, the time-distance main factor is marked as the jetting time-distance main factor; when the grey relational coefficient of a construction unit is not in the first position, the time-distance main factor is marked as the stable forming main factor. The sequence determination is performed on the phase principal marker, energy principal marker, and time-distance principal marker, as follows: When there are two or more identical phase principal markers, energy principal markers, and time-distance principal markers, the identical principal markers are recorded as the recurrence principal factors. When the phase main factor label, energy main factor label, and time distance main factor label are all different, if the time distance main factor label is the injection pressure time distance main factor, then the injection pressure time distance main factor is recorded as the return main factor; otherwise, the phase main factor label is recorded as the return main factor.

[0011] Preferably, the absolute value of the residual value of the rolling construction band at each measuring point in the rolling construction band sequence is taken to generate the residual amplitude of each measuring point. The residual amplitudes of each measuring point are then arranged in descending order of value. The arranged measuring point number, measuring point mileage and measuring point lateral position are then combined to form a control measuring point sequence.

[0012] Preferably, each completed historical construction control process is taken as a historical sample. The recurring principal factors, control point sequences, and construction parameter control paths in the same historical sample are extracted. A finite state path adjudication model is established based on a finite state machine model. The construction parameter control paths are used as the state set of the finite state path adjudication model. The recurring principal factors, control point sequences, and construction parameter control paths in the historical samples are input into the finite state path adjudication model for model training. After training is completed, the current recurring principal factors and control point sequences are input into the finite state path adjudication model to determine the current construction parameter control path, as detailed below. When the main return factor is the main cause of the shaping residual, and the control point sequence meets the control judgment condition for the shaping residual, the construction parameter control path outputs the cross-scraping and re-rolling path; the cross-scraping and re-rolling path: cross-scraping and re-rolling are performed with the control point sequence as the order of the operation points; When the main factor of compaction recurrence is the main cause of compaction recurrence, and the control point sequence meets the compaction recurrence control judgment condition, the construction parameter control path outputs the harrowing, remixing and re-rolling path; the harrowing, remixing and re-rolling path: harrowing, remixing and re-rolling are performed in the order of the control point sequence; When the main return factor is the spraying time distance, and the control measuring point sequence meets the spraying time distance control judgment condition, the construction parameter control path outputs the spraying time distance reset remixing and rerolling path; the spraying time distance reset remixing and rerolling path: first, record the end time of composite stabilizer spraying and the end time of rerolling according to the spraying time distance, and then execute remixing and rerolling according to the control measuring point sequence as the operation measuring point order; When the main return factor is the stable forming factor and the control measurement point sequence meets the forming admission judgment condition, the construction parameter control path output is the direct re-rolling maintenance path; the direct re-rolling maintenance path: execute the curing after re-rolling.

[0013] Preferably, operation control is performed on the current construction unit according to the construction parameter control path, and the post-re-rolling elevation is extracted from the current construction unit after operation control. The post-re-rolling elevation program sequence is generated by arranging the measuring points. Then, the residual calculation is performed on the post-re-rolling elevation program sequence item by item using the loose paving benchmark elevation program sequence as the deduction benchmark to generate the post-re-rolling residual sequence.

[0014] Preferably, the initial rolling residual sequence, the leveling residual sequence, and the controlled re-rolling residual sequence are combined to form a controlled three-phase residual sequence, and the controlled return principal factor is generated iteratively based on the controlled three-phase residual sequence to control the base course construction parameters, as follows; When the main factor of the control return is the stable forming main factor, maintain the current construction parameter control path and stop generating new scraping, rake loosening, remixing and spraying time distance adjustment instructions for the current construction unit; When the main factor of the post-control return is the main factor of the shaping residual, a new control measurement point sequence is generated based on the post-control re-rolling residual sequence, and the construction parameter control path is set as the cross scraping and re-rolling path. When the main factor of post-control recurrence is the main cause of compaction recurrence, a new control measurement point sequence is generated based on the post-control re-rolling residual sequence, and the construction parameter control path is set to the harrowing, re-mixing, and re-rolling path. When the main factor of the post-control return is the jetting time distance, a new control measurement point sequence is generated based on the post-control re-rolling residual sequence, and the construction parameter control path is set as the jetting time distance reset re-mixing and re-rolling path.

[0015] This invention provides a method for acquiring and controlling construction parameters of polymer composite stabilized soil beam field base. It has the following beneficial effects: (1) This method divides the construction units and generates a measurement point sequence, incorporating the edge pile measurement points, construction centerline measurement points, and two side construction edgeline measurement points into a unified measurement point sequence. It extracts benchmark parameters, time-phase elevation sequence, and spraying time interval from measurement and layout records, composite stabilizer spraying records, initial rolling measurement records, leveling measurement records, and re-rolling measurement records. Based on the edge pile elevation, design longitudinal slope, design transverse slope, and loose paving thickness, a loose paving benchmark elevation sequence is generated. Then, using the loose paving benchmark elevation sequence as a deduction benchmark, initial rolling residual sequence, leveling residual sequence, and re-rolling residual sequence are generated, forming a three-time-phase residual sequence. Thus, this method can incorporate the construction location, elevation change, the end time of composite stabilizer spraying, the end time of re-rolling, and the spraying time interval into the same data chain, transforming the construction status of the polymer composite stabilized soil beam yard base course from manual experience judgment to continuous judgment based on the measurement point sequence and the three-time-phase residual sequence, achieving the purpose of quantitative analysis of the base course elevation deviation.

[0016] (2) Based on the three-phase residual sequences, this method performs discrete wavelet transform and multi-scale band reconstruction on the initial rolling residual sequences, leveling residual sequences, and re-rolling residual sequences to generate initial rolling construction band sequences, leveling construction band sequences, and re-rolling construction band sequences, respectively. The method then constructs the return phase value using the primary peak values ​​of the initial-leveling cross-correlation, initial-re-re-rolling cross-correlation, and re-re-rolling cross-correlation; the method constructs the return energy value using the leveling construction band energy value and the re-rolling construction band energy value; and the method constructs the time-distance correlation value using the injection time-distance sequence and the return energy reference sequence. Subsequently, the method performs ordinal determination based on the return phase value, return energy value, and time-distance correlation value to generate the return principal factor. Compared to current techniques that rely solely on post-rolling elevation and smoothness testing or field experience for judgment, this method can distinguish the main causes of shaping residuals, compaction recurrence, spraying time intervals, and stable forming. This allows the judgment of construction deviations to move beyond the result level and instead analyze the causes of deviations around the initial rolling construction wave sequence, the leveling construction wave sequence, the retilling construction wave sequence, and the spraying time interval.

[0017] (3) This method generates a control measuring point sequence based on the residual values ​​of each measuring point in the rolling construction band sequence, and inputs the return principal factor and the control measuring point sequence into the finite state path adjudication model to determine the construction parameter control path, so that the current construction unit can carry out operation control according to the cross-scraping rolling path, the harrowing and remixing rolling path, the spraying time-distance reset remixing rolling path, or the direct rolling and maintaining path. After operation control, the control-post rolling height program sequence is obtained, and the control-post rolling residual sequence is generated using the loose paving reference height program sequence as the deduction reference. The initial rolling residual sequence, the scraping residual sequence, and the control-post rolling residual sequence are combined to form the control-post three-phase residual sequence, and the control-post return principal factor is generated again. Therefore, this method forms a closed-loop construction control process, from benchmark parameters, time-phase height sequence, spraying time interval, loose paving benchmark height sequence, three-time-phase residual sequence, to return principal factors, control measuring point sequence, construction parameter control path, control post-re-rolling height sequence, control post-re-rolling residual sequence, and control post-return principal factors. This allows construction instructions to be adjusted around abnormal measuring points and return principal factors, improving the current problems of insufficient rework basis, general operation path, and scattered verification process in construction control. It achieves the effects of standardizing the base elevation morphology, stabilizing the post-re-rolling forming state, and supporting the continuous construction control of the base in the beam yard.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] Please see Figure 1 This invention provides a method for collecting and controlling construction parameters of polymer composite stabilized soil beam yard base course. To achieve the above objectives, this invention is implemented through the following technical solution: including: The construction unit is divided and a sequence of measuring points is generated. The reference parameters, time phase height program sequence and spraying time distance of each measuring point are extracted from the construction record and a loose paving reference height program sequence is generated. The time phase height program sequence in the loose paving reference height program sequence is calculated to generate a three-time phase residual sequence. Multi-scale band reconstruction of the three-phase residual sequence yields the initial rolling construction band sequence, the leveling construction band sequence, and the re-rolling construction band sequence. The returned phase value, returned energy value, and time distance correlation value are constructed, and the order is compared and the order decision is performed to generate the returned principal factor. A control point sequence was constructed based on the rolling construction band sequence, and the control path of construction parameters was determined together with the return principal factor. Based on the construction parameter control path, the current construction unit is controlled and the post-control re-rolling height program sequence is obtained. The post-control re-rolling height program sequence is used to perform residual calculation to generate the post-control re-rolling residual sequence. The post-control three-phase residual sequence is then assembled and iterated to generate the post-control return principal factor to execute the base construction parameter control.

[0021] In this embodiment, a unified data acquisition foundation is established around the current construction unit. Taking the construction of the polymer composite stabilized soil base course of the Dingtao beam yard as an example, control lines are usually first laid out on the outer side of the road edge, and measuring points are laid out in conjunction with the road centerline, the left construction edge line, and the right construction edge line. Between two adjacent edge stakes, the base course area can be taken as the current construction unit, and a sequence of measuring points is generated according to the ascending order of mileage coordinates and the order of cross-sectional coordinates. Within the current construction unit, the construction personnel first obtain the benchmark parameters, including the edge stake elevation, design longitudinal slope, design cross slope, and loose paving thickness; then, they obtain the time-phase height sequence, which includes the height sequence after initial rolling, the height sequence after leveling, and the height sequence after re-rolling; at the same time, they obtain the spraying time interval, which is generated by the time interval between the end of the composite stabilizer spraying and the end of the re-rolling. For example, after the current construction unit completes paving, composite stabilizer spraying, cement spreading, and road mixing, a road roller is used for rapid initial rolling, and surveyors collect the elevation sequence after initial rolling. After leveling with a bulldozer or grader, the elevation sequence after leveling is collected. After re-rolling, the elevation sequence after re-rolling is collected. Then, based on the edge stake elevation, design longitudinal slope, design transverse slope, and loose paving thickness, a loose paving reference elevation sequence is generated. Residual calculations are then performed on the elevation sequences after initial rolling, leveling, and re-rolling, forming the initial rolling residual sequence, leveling residual sequence, and re-rolling residual sequence. These three sequences form a three-phase residual sequence. Therefore, the elevation changes of each measuring point within the current construction unit can be continuously unfolded along the three construction phases of initial rolling, leveling, and re-rolling. Construction personnel no longer rely solely on the single elevation result after re-rolling to judge the base course condition but can instead observe the changes at the same measuring point in different construction processes.

[0022] After the three-phase residual sequences are formed, multi-scale band reconstruction is further performed on the initial rolling residual sequence, leveling residual sequence, and re-rolling residual sequence to generate initial rolling construction band sequences, leveling construction band sequences, and re-rolling construction band sequences. Then, order comparison is performed based on the returned phase value, returned energy value, and time-distance correlation value, followed by order adjudication to generate the returned principal factor. Taking a section of the base course of a construction access road as an example, after the excavator initially paves the road, a 22-ton pneumatic tire roller quickly compacts it one or two times, potentially exposing unevenness in the wheel track zone or joint zone. After leveling, some unevenness is smoothed out, but after re-rolling, elevation fluctuations reappear at the same measuring point. Current practices often directly interpret this phenomenon as "insufficient re-rolling" or "inadequate leveling," and then arrange for repeated rolling or re-leveling. The source of fluctuations is determined by the band variations between the initial rolling, leveling, and re-rolling construction band sequences: if the fluctuation in the initial rolling band sequence reappears in the re-rolling band sequence and occupies a leading position in the returned phase value, the main return factor is more likely to be the main cause of compaction recurrence; if the fluctuation in the leveling band sequence continues in the re-rolling band sequence and occupies a leading position in the returned energy value, the main return factor is more likely to be the main cause of shaping residuals; if the time-distance correlation value between the spraying time-distance and the returned energy reference sequence occupies a leading position in the construction unit time-distance energy queue, the main return factor is more likely to be the main cause of spraying time-distance. In this way, the elevation anomaly after re-rolling can be decomposed into the main causes of shaping residuals, compaction recurrence, spraying time-distance, and stable shaping, providing a clearer process basis for determining the construction parameter control path.

[0023] After the principal factor is generated, a control measuring point sequence is constructed based on the residual values ​​of each measuring point in the rolling construction band sequence. Then, the control path of the construction parameters is determined by combining the principal factor, and iterative judgment is carried out after the operation is controlled. Taking the common issue of "undulations still appearing at the joints after scraping and re-rolling" in the base construction of the Dingtao beam yard as an example, if the main cause of the recurrence is the shaping residual, the current construction parameter control path can be determined as the cross-scraping and re-rolling path. Construction personnel should prioritize the treatment of joints and areas with concentrated elevation differences according to the positions of the control points that are ranked earlier in the control point sequence. If the main cause of the recurrence is the compaction recurrence, the current construction parameter control path can be determined as the loosening, remixing, and re-rolling path. Construction personnel should loosen, remix, and re-roll the base surface around the key control points in the control point sequence. If the main cause of the recurrence is the spraying time interval, the current construction parameter control path can be determined as the spraying time interval reset, remixing, and re-rolling path. Construction personnel should re-record the end time of the composite stabilizer spraying and the end time of the re-rolling, and organize the remixing and re-rolling with the new spraying time interval. If the main cause of the recurrence is the stabilization and shaping, the current construction parameter control path can be determined as the direct re-rolling and maintenance path, and proceed to post-re-rolling curing. After operational control, the post-control re-rolling height program sequence is acquired. Residual calculations are performed on this sequence to generate a post-control re-rolling residual sequence. The initial rolling residual sequence, leveling residual sequence, and post-control re-rolling residual sequence are then combined to form a three-phase post-control residual sequence, generating the post-control return principal factor. This process involves tasks such as construction unit division, measuring point sequence generation, benchmark parameter acquisition, phase height program sequence acquisition, spraying time interval acquisition, loose-lay benchmark height program sequence generation, three-phase residual sequence generation, multi-scale band reconstruction, return principal factor generation, control measuring point sequence construction, construction parameter control path determination, post-control re-rolling residual sequence generation, and iterative judgment of the post-control return principal factor. Compared to existing methods that rely on manual experience, phased measurements, and post-construction rework for base course construction control, this method transforms the construction of polymer composite stabilized soil beam yard base courses from "addressing unevenness after discovery" to "controlling the course after determining the cause based on changes in residual error during construction," thereby achieving continuous control over base course flatness fluctuations, compaction recurrence, shaping residual error, and abnormal spraying time intervals. Example 2

[0024] Please refer to Figure 2 Specifically: along the construction direction of the base layer, the base layer area between two adjacent side piles is determined as the longitudinal range of the construction unit. Within the current longitudinal range, the construction center line is used as the lateral positioning reference, and the left and right side lines are used as the lateral boundaries to enclose and form a construction unit. Each construction unit is assigned a unique construction unit number. Using the edge stake measuring points, construction centerline measuring points, and measuring points on both sides of the construction edgeline within the construction unit as the source of measuring points, the measuring points are sorted according to the ascending order of mileage coordinates. The measuring points with the same mileage coordinates are sorted according to the direction from one side of the construction edgeline to the other side of the construction edgeline based on the cross-sectional coordinates, thus forming a measuring point sequence. Based on the API interface, the construction parameters of each measuring point are extracted from the construction records, including the reference parameters, the time phase height program sequence, and the injection time distance; Construction records include surveying and setting out records, composite stabilizer spraying records, initial rolling surveying records, leveling surveying records, and re-rolling surveying records; Extract the edge pile elevation, design longitudinal slope, design transverse slope, and loose paving thickness from the survey and layout records to form benchmark parameters; Extract the post-roughing elevation from the initial rolling measurement records of the current construction unit, and generate a post-roughing elevation sequence by arranging the measuring points. Extract the leveling elevation from the leveling measurement records of the current construction unit, and generate a leveling elevation sequence by arranging the measurement points. Extract the post-re-rolling elevation from the re-rolling measurement records of the current construction unit, and generate a post-re-rolling elevation sequence by arranging the measurement points; The high-speed sequence after initial rolling, the high-speed sequence after leveling, and the high-speed sequence after re-rolling constitute the phase high-speed sequence; Extract the end time of composite stabilizer spraying from the composite stabilizer spraying record of the current construction unit, extract the end time of re-rolling from the re-rolling measurement record of the current construction unit, and generate the spraying pressure time interval based on the time interval between the end time of composite stabilizer spraying and the end time of re-rolling.

[0025] Using the edge pile elevation, design longitudinal slope, and design transverse slope as input data, the RANSAC robust fitting technology is used to fit the measuring point sequence to generate a compaction benchmark elevation sequence. The loose paving thickness is then matched with the measuring point sequence to form a loose paving correction sequence. Finally, the compaction benchmark elevation of each measuring point in the compaction benchmark elevation sequence is superimposed with the loose paving correction value of the same measuring point in the loose paving correction sequence to generate a loose paving benchmark elevation sequence. Using the loose-laying benchmark high program series as the deduction benchmark, the high program series after initial rolling, the high program series after leveling, and the high program series after re-rolling are subjected to difference processing to generate the initial rolling residual sequence, the leveling residual sequence, and the re-rolling residual sequence. Based on the construction phase sequence of initial rolling, leveling, and re-rolling, a three-phase residual sequence is formed.

[0026] In this embodiment, the current construction range is first analyzed by combining the construction direction of the polymer composite stabilized soil beam yard base, two adjacent side piles, the construction center line, the left side line, and the right side line. The base area between two adjacent side piles is determined as the longitudinal range of the construction unit. The construction center line is used as the lateral positioning reference, and the left side line and the right side line are used as the lateral boundaries to enclose and form a construction unit. Then, a unique construction unit number is assigned to each construction unit. For example, in the base filling construction of the Dingtao beam yard construction access road, a section of base between two adjacent side piles is taken as a construction unit. The side pile measuring points, construction center line measuring points, and measuring points on both sides of the construction side line within the construction unit are used as measuring point sources. The measuring points are sorted according to the ascending order of the mileage coordinates. The measuring points with the same mileage coordinates are sorted according to the direction from one side of the construction side line to the other side of the construction side line according to the cross-sectional coordinates to form a measuring point sequence. Subsequently, construction parameters for each measuring point are extracted from the surveying and setting-out records, composite stabilizer spraying records, initial rolling measurement records, leveling measurement records, and re-rolling measurement records using the API interface. Specifically, the edge pile elevation, design longitudinal slope, design transverse slope, and loose paving thickness are extracted from the surveying and setting-out records to form benchmark parameters. The initial rolling elevation is extracted from the initial rolling measurement records of the current construction unit and arranged by measuring points to generate an initial rolling elevation sequence. The leveling elevation is extracted from the leveling measurement records of the current construction unit and arranged by measuring points to generate a leveling elevation sequence. The re-rolling elevation is extracted from the re-rolling measurement records of the current construction unit and arranged by measuring points to generate a re-rolling elevation sequence. The initial rolling elevation sequence, leveling elevation sequence, and re-rolling elevation sequence form a phase elevation sequence. The composite stabilizer spraying end time is extracted from the composite stabilizer spraying records of the current construction unit, and the re-rolling end time is extracted from the re-rolling measurement records of the current construction unit. The spraying time interval is generated based on the time interval between the composite stabilizer spraying end time and the re-rolling end time. Subsequently, using the edge pile elevation, design longitudinal slope, and design transverse slope as input data, the RANSAC robust fitting technology was used to fit the measuring point sequence to generate a compaction reference height program. The loose paving thickness was then matched with the measuring point sequence to form a loose paving correction sequence. Finally, the compaction reference elevation of each measuring point in the compaction reference height program was superimposed with the loose paving correction value of the same measuring point in the loose paving correction sequence to generate a loose paving reference height program. Through the above implementation methods, this method forms a continuous data chain consisting of construction unit number, measuring point sequence, benchmark parameters, phase height sequence, spraying time interval, compaction benchmark height sequence, loose paving correction sequence, loose paving benchmark height sequence, initial rolling residual sequence, leveling residual sequence, re-rolling residual sequence, and three-phase residual sequence. The purpose is to transform the scattered on-site measurement and layout records, composite stabilizer spraying records, initial rolling measurement records, leveling measurement records, and re-rolling measurement records into comparable elevation residual results within the same construction unit, enabling construction personnel to clearly see the elevation changes of the same measuring point in the three construction phases of initial rolling, leveling, and re-rolling. Example 3

[0027] Please refer to Figure 2 Specifically: the residual sequences of the initial rolling, leveling, and re-rolling are decomposed into multiple scales using discrete wavelet transform to obtain the wavelet decomposition components of each residual sequence at different scales. Then, based on the distance between adjacent measuring points in the measuring point sequence, the spatial wavelength range represented by each wavelet decomposition component is statistically analyzed. Combined with the working width, travel speed, and sampling interval of the construction equipment in the initial rolling, leveling, and re-rolling processes, the construction disturbance band range of each process is obtained. Wavelet decomposition components whose spatial wavelength range falls within the construction disturbance band range are selected for reconstruction to generate the initial rolling construction band sequence, leveling construction band sequence, and re-rolling construction band sequence, respectively. A sequence slip set is defined, and normalized cross-correlation is performed on the initial rolling construction band sequence, the leveling construction band sequence, and the re-rolling construction band sequence based on the sequence slip set to obtain the return phase value; wherein, the sequence slip set consists of integer slip values, each integer slip value representing the number of measuring points that a construction band sequence moves relative to another construction band sequence along the construction unit measuring point sequence; Normalized cross-correlation operations include: Using the initial rolling construction band sequence as the fixed sequence and the leveling construction band sequence as the slip sequence, the leveling construction band sequence is moved according to each integer slip amount in the sequence slip set. After each move, the normalized product of the initial rolling construction band sequence and the moved leveling construction band sequence is summed to generate the initial cross-correlation sequence. The cross-correlation number with the highest value in the initial cross-correlation sequence is recorded as the primary peak value of the initial cross-correlation. Using the initial rolling construction band sequence as the fixed sequence and the secondary rolling construction band sequence as the slip sequence, the secondary rolling construction band sequence is moved according to each integer slip amount in the sequence slip set. After each move, the normalized product of the initial rolling construction band sequence and the moved secondary rolling construction band sequence is summed to generate the initial-reverse cross-correlation sequence. The cross-correlation number with the highest numerical value in the initial-reverse cross-correlation sequence is recorded as the primary peak value of the initial-reverse cross-correlation. Using the leveling construction band sequence as the fixed sequence and the re-rolling construction band sequence as the slip sequence, the re-rolling construction band sequence is moved according to each integer slip amount in the sequence slip set. After each move, the normalized product of the leveling construction band sequence and the moved re-rolling construction band sequence is summed to generate the leveling-re-rolling cross-correlation sequence. The cross-correlation number with the highest numerical value in the leveling-re-rolling cross-correlation sequence is recorded as the main peak value of the leveling-re-rolling cross-correlation. The initial cross-correlation peak value, the initial complex cross-correlation peak value, and the complex cross-correlation peak value are arranged in descending order of value, and the position of the initial complex cross-correlation peak value in the arrangement result is recorded as the return phase value.

[0028] The energy value of the leveling construction band is generated by summing the squares of the residual values ​​of the leveling construction band at each measuring point in the leveling construction band sequence. The energy value of the rolling construction band is generated by summing the squares of the residual values ​​of the rolling construction band at each measuring point in the rolling construction band sequence. The energy values ​​of the leveling construction band and the rolling construction band are arranged in descending order of value, and the position of the rolling construction band energy value in the arrangement result is recorded as the return energy value. Among them, the residual value of the leveling construction band is the value of the leveling residual sequence after reconstruction within the construction disturbance band range at the current measuring point; the residual value of the re-rolling construction band is the value of the re-rolling residual sequence after reconstruction within the construction disturbance band range at the current measuring point. The current construction unit and the construction units that have obtained the return energy value before the current construction unit are sorted according to the construction sequence to form a construction unit time-distance energy queue. The injection time distance and return energy value in the construction unit time-distance energy queue are dimensionless to form an injection time distance sequence and a return energy reference sequence. The return energy sequence is used as the reference sequence and the injection time distance sequence is used as the comparison sequence. The grey relational coefficient of the current construction unit is calculated according to the grey relational coefficient algorithm. The grey relational coefficient under the current construction unit number is read and recorded as the time-distance relational value. The calculation process of the grey relational coefficient algorithm is as follows: Calculate the absolute difference Δ between the return energy reference sequence and the injection time-distance sequence under each construction unit number. (k) And read the minimum difference Δ among all absolute differences. min and the maximum difference Δ max Calculate the grey relational coefficient. ,in, This represents the grey relational coefficient.

[0029] The return principal factor is generated based on the return phase value, return energy value, and time-distance correlation value; When the peak value of the initial complex cross-correlation is in the first order in the arrangement results, the phase main cause is marked as the compaction return main cause; when the peak value of the initial scraping cross-correlation is in the first order in the arrangement results, the phase main cause is marked as the shaping residual main cause; when the peak value of the scraping complex cross-correlation is in the first order in the arrangement results, the phase main cause is marked as the stable forming main cause. When the energy value of the rolling construction band is in the first position in the arrangement results, the main energy cause is marked as the main cause of compaction recurrence; when the energy value of the leveling construction band is in the first position in the arrangement results, the main energy cause is marked as the main cause of shaping residual. When the grey relational coefficient of a construction unit is in the first position in the construction unit time-distance energy queue, the time-distance main factor is marked as the jetting time-distance main factor; when the grey relational coefficient of a construction unit is not in the first position, the time-distance main factor is marked as the stable forming main factor. The sequence determination is performed on the phase principal marker, energy principal marker, and time-distance principal marker, as follows: When there are two or more identical phase principal markers, energy principal markers, and time-distance principal markers, the identical principal markers are recorded as the recurrence principal factors. When the phase main factor label, energy main factor label, and time distance main factor label are all different, if the time distance main factor label is the injection pressure time distance main factor, then the injection pressure time distance main factor is recorded as the return main factor; otherwise, the phase main factor label is recorded as the return main factor.

[0030] In this embodiment, based on the already obtained initial milling residual sequence, leveling residual sequence, and re-milling residual sequence, the initial milling residual sequence, leveling residual sequence, and re-milling residual sequence are first decomposed into multiple scales according to discrete wavelet transform to obtain the wavelet decomposition components of the initial milling residual sequence, the leveling residual sequence, and the re-milling residual sequence at different scales. Then, based on the spacing between adjacent measuring points in the measuring point sequence, the spatial wavelength range represented by each wavelet decomposition component is statistically analyzed, and combined with the initial milling process. The operating width, travel speed, and sampling interval of the medium roller, the operating width, travel speed, and sampling interval of the bulldozer or grader in the leveling process, and the operating width, travel speed, and sampling interval of the roller in the re-rolling process are obtained to acquire the construction disturbance band range of the primary rolling process, the construction disturbance band range of the leveling process, and the construction disturbance band range of the re-rolling process. Wavelet decomposition components whose spatial wavelength range falls within the construction disturbance band range are selected for reconstruction to generate the primary rolling construction band sequence, the leveling construction band sequence, and the re-rolling construction band sequence, respectively. Taking the polymer composite stabilized soil base course of the construction access road at the Dingtao beam fabrication yard as an example, after site leveling, construction layout, soil laying, dilution of stabilizer, spreading of cementitious materials by a sprayer, mixing by a road mixer, trimming by a bulldozer, and compaction by a road roller, a certain construction unit may exhibit continuous wheel track fluctuations along the direction of the road roller's travel after initial rolling. After leveling, undulations may remain at the joints, and after re-rolling, elevation reappears at nearby measuring points. By retaining the residual wavebands related to the disturbance of construction equipment through the initial rolling construction waveband sequence, the leveling construction waveband sequence, and the re-rolling construction waveband sequence, and eliminating scattered measurement fluctuations that are inconsistent with the range of the construction disturbance waveband, subsequent judgments are focused on the elevation changes during the actual construction process of the current construction unit. Subsequently, a sequence slip set consisting of integer slip values ​​is defined, and normalized cross-correlation operations are performed on the initial rolling construction band sequence, the leveling construction band sequence, and the re-rolling construction band sequence based on the sequence slip set: Using the initial rolling construction band sequence as the fixed sequence and the leveling construction band sequence as the slip sequence, an initial-leveling cross-correlation sequence is generated, and the cross-correlation coefficient with the highest numerical value in the initial-leveling cross-correlation sequence is recorded as the primary peak value of the initial-leveling cross-correlation; using the initial rolling construction band sequence as the fixed sequence and the re-rolling construction band sequence as the slip sequence, an initial-re-leveling cross-correlation sequence is generated... The correlation sequence is generated, and the cross-correlation coefficient with the highest numerical value in the initial and complex cross-correlation sequence is recorded as the primary peak value of the initial and complex cross-correlation. The scraping construction band sequence is used as the fixed sequence, and the rolling construction band sequence is used as the slip sequence to generate the scraping and complex cross-correlation sequence. The cross-correlation coefficient with the highest numerical value in the scraping and complex cross-correlation sequence is recorded as the primary peak value of the scraping and complex cross-correlation. The primary peak value of the initial scraping cross-correlation, the primary peak value of the initial and complex cross-correlation, and the primary peak value of the scraping and complex cross-correlation are arranged in descending order of numerical value, and the position of the primary peak value of the initial and complex cross-correlation in the arrangement result is recorded as the return phase value.Simultaneously, the residual values ​​of the leveling construction bands at each measuring point in the leveling construction band sequence are summed by squares to generate the energy value of the leveling construction band; the residual values ​​of the rolling construction bands at each measuring point in the rolling construction band sequence are summed by squares to generate the energy value of the rolling construction band; then, the energy values ​​of the leveling construction band and the rolling construction band are arranged in descending order of value, and the position of the rolling construction band energy value in the arrangement result is recorded as the return energy value. For multiple construction units in continuous construction, the current construction unit and the construction units whose return energy values ​​have been obtained before the current construction unit are sorted according to the construction sequence to form a construction unit time-distance energy queue. The spraying time distance and return energy value in the construction unit time-distance energy queue are dimensionless to form a spraying time distance sequence and a return energy reference sequence. Using the return energy reference sequence as the reference sequence and the spraying time distance sequence as the comparison sequence, the grey relational coefficient of the current construction unit is calculated according to the grey relational coefficient algorithm, and the grey relational coefficient under the current construction unit number is recorded as the time-distance relational value. Finally, the return principal factors are generated based on the return phase value, return energy value, and time-distance correlation value: when the initial complex cross-correlation principal peak value is in the first order in the arrangement results, the phase principal factor is marked as the compaction return principal factor; when the initial scraping cross-correlation principal peak value is in the first order in the arrangement results, the phase principal factor is marked as the shaping residual principal factor; when the scraping complex cross-correlation principal peak value is in the first order in the arrangement results, the phase principal factor is marked as the stable forming principal factor; when the energy value of the rolling construction band is in the first order in the arrangement results, the energy... The main cause is marked as the compaction return main cause; when the energy value of the leveling construction band is in the first order in the arrangement results, the energy main cause is marked as the shaping residual main cause; when the grey relational coefficient of the construction unit is in the first order in the construction unit time-distance energy queue, the time-distance main cause is marked as the spraying time-distance main cause; when the grey relational coefficient of the construction unit is not in the first order, the time-distance main cause is marked as the stable forming main cause; then the order decision is performed on the phase main cause mark, energy main cause mark and time-distance main cause mark to generate the return main factor. Through the above implementation methods, this method transforms the initial rolling residual sequence, leveling residual sequence, and re-rolling residual sequence into initial rolling construction band sequences, leveling construction band sequences, and re-rolling construction band sequences that can reflect the disturbance characteristics of construction equipment. It also incorporates the phase continuity of elevation recurrence, residual energy concentration, and the influence of spraying time distance into the same judgment process. The purpose is to determine whether the elevation anomaly after re-rolling originates from the main cause of shaping residual, compaction recurrence, spraying time distance, or stable shaping. Compared with the current method of relying on post-re-rolling elevation sampling, manual observation of wheel tracks, or experience to judge joint undulations, this method can incorporate "where elevation recurrence occurs" and "why recurrence occurs" into the analysis process before construction parameter control. Example 4

[0031] Please refer to Figure 2Specifically: Take the absolute value of the residual value of the rolling construction band at each measuring point in the rolling construction band sequence to generate the residual amplitude of each measuring point, and arrange the residual amplitudes of each measuring point in descending order of value. Then, form a control measuring point sequence by arranging the measured point number, measuring point mileage and measuring point lateral position. When the residual amplitudes of two or more measuring points are the same, arrange them in ascending order of measuring point number according to the same residual amplitude.

[0032] Each completed historical construction control process is taken as a historical sample. The recurring principal factors, control point sequences, and construction parameter control paths are extracted from the same historical sample. A finite state path adjudication model is established based on the finite state machine model. The construction parameter control paths are used as the state set of the finite state path adjudication model. The recurring principal factors, control point sequences, and construction parameter control paths from the historical samples are input into the finite state path adjudication model for model training. After training is completed, the current recurring principal factors and control point sequences are input into the finite state path adjudication model to determine the current construction parameter control path, as detailed below. When the main return factor is the main cause of the shaping residual, and the control point sequence meets the control judgment condition for the shaping residual, the construction parameter control path outputs the cross-scraping and re-rolling path; the cross-scraping and re-rolling path: cross-scraping and re-rolling are performed with the control point sequence as the order of the operation points; When the main factor of compaction recurrence is the main cause of compaction recurrence, and the control point sequence meets the compaction recurrence control judgment condition, the construction parameter control path outputs the harrowing, remixing and re-rolling path; the harrowing, remixing and re-rolling path: harrowing, remixing and re-rolling are performed in the order of the control point sequence; When the main return factor is the spraying time distance, and the control measuring point sequence meets the spraying time distance control judgment condition, the construction parameter control path outputs the spraying time distance reset remixing and rerolling path; the spraying time distance reset remixing and rerolling path: first, record the end time of composite stabilizer spraying and the end time of rerolling according to the spraying time distance, and then execute remixing and rerolling according to the control measuring point sequence as the operation measuring point order; When the main return factor is the stable forming factor and the control measurement point sequence meets the forming admission judgment condition, the construction parameter control path output is the direct re-rolling maintenance path; the direct re-rolling maintenance path: execute the curing after re-rolling.

[0033] In this embodiment, the locations of the measuring points that need to be prioritized for control are determined based on the rolling construction band sequence. The absolute values ​​of the rolling construction band residuals of each measuring point in the rolling construction band sequence are taken to generate the residual amplitude of each measuring point. The residual amplitudes of each measuring point are arranged in descending order of value. Then, the measured point number, measuring point mileage, and measuring point lateral position are combined to form a control measuring point sequence. When the residual amplitudes of two or more measuring points are the same, they are arranged in ascending order of the measuring point number with the same residual amplitude. Taking the construction of the base course of the high-polymer composite stabilized soil beam yard as an example, after the current construction unit has gone through construction layout, soil laying, dilution of stabilizer, spreading of cementitious material by sprinkler truck, mixing by road mixer, trimming by bulldozer, initial rolling, leveling and re-rolling, if the re-rolling construction band sequence shows that there are re-rolling construction band residual values ​​at the right construction edge measuring point, construction center line measuring point and left construction edge measuring point near a certain measuring point mileage, then the entire section will not be directly reworked. Instead, a control measuring point sequence will be generated according to the magnitude of the residual amplitude, so that the construction personnel can first deal with the measuring point positions where the elevation fluctuation is more concentrated after re-rolling. Subsequently, each completed historical construction control process is taken as a historical sample. The recurring principal factors, control point sequences, and construction parameter control paths are extracted from the same historical sample. A finite state path adjudication model is established based on a finite state machine model. The construction parameter control paths are used as the state set of the finite state path adjudication model. The recurring principal factors, control point sequences, and construction parameter control paths from the historical samples are then input into the finite state path adjudication model for model training. After training, the current recurring principal factors and control point sequences are input into the finite state path adjudication model to determine the current construction parameter control path. If the current primary return factor is the main cause of shaping residuals, and the control point sequence meets the control judgment conditions for shaping residuals, then the construction parameter control path outputs a cross-scraping and re-rolling path, and the construction personnel perform cross-scraping and re-rolling according to the operation point sequence of the control point sequence; if the current primary return factor is the main cause of compaction return, and the control point sequence meets the control judgment conditions for compaction return, then the construction parameter control path outputs a rake-loosening, remixing, and re-rolling path, and the construction personnel perform rake-loosening, remixing, and re-rolling according to the operation point sequence of the control point sequence; if the current primary return factor is the main cause of compaction return, and the control point sequence meets the control judgment conditions for compaction return, then the construction parameter control path outputs a rake-loosening, remixing, and re-rolling path; if the current primary return factor is the main cause of compaction return, then the construction parameter control path outputs a rake-loosening, remixing, and re-rolling path. If the main factor is the spraying time interval, and the control measurement point sequence meets the spraying time interval control judgment condition, then the construction parameter control path outputs the spraying time interval reset remixing and rerolling path. The construction personnel first record the end time of the composite stabilizer spraying and the end time of rerolling according to the spraying time interval, and then perform remixing and rerolling according to the operation measurement point sequence of the control measurement point sequence. If the current main factor is the stabilization molding main factor, and the control measurement point sequence meets the molding access judgment condition, then the construction parameter control path outputs the direct rerolling maintenance path, and the construction personnel perform post-rerolling curing.Through the above implementation method, the residual values, residual amplitudes, measuring point numbers, measuring point mileage, measuring point lateral positions, control measuring point sequences, return principal factors, and construction parameter control paths of the re-rolling construction bands are connected into an executable construction control process. The purpose is to simultaneously determine "where to handle after re-rolling" and "which construction parameter control path should be used." Compared to the current common practice of relying on post-re-rolling elevation sampling results for whole-section leveling, repeated rolling, or manual adjustment based on experience, this method converges the control position to key measuring points in the control measuring point sequence. Based on the main factors of shaping residuals, compaction return, spraying time interval, and stabilization, it selects cross-leveling re-rolling paths, rake-loosening and re-mixing re-rolling paths, spraying time interval reset and re-mixing re-rolling paths, or direct re-rolling to maintain the path. This makes the operation sequence, control position, and control actions of polymer composite stabilized soil beam yard base construction clearer, and the construction records, re-rolling band analysis results, and on-site handling actions easier to verify. Example 5

[0034] Please refer to Figure 2 Specifically: Based on the construction parameter control path, the current construction unit is subjected to operation control, and after the operation control, the post-re-rolling elevation is extracted from the current construction unit. The post-re-rolling elevation program is generated by arranging the measuring points. Then, the post-re-rolling elevation program is calculated item by item using the loose paving benchmark elevation program as the deduction benchmark to generate the post-re-rolling residual sequence.

[0035] S4 includes S42; The residual sequence of initial rolling, the residual sequence of leveling, and the residual sequence of controlled re-rolling are combined to form the residual sequence of the three time phases after control. Based on the residual sequence of the three time phases after control, the control return principal factor is generated to control the base construction parameters, as follows; When the main factor of the control return is the stable forming main factor, maintain the current construction parameter control path and stop generating new scraping, rake loosening, remixing and spraying time distance adjustment instructions for the current construction unit; When the main factor of the post-control return is the main factor of the shaping residual, a new control measurement point sequence is generated based on the post-control re-rolling residual sequence, and the construction parameter control path is set as the cross scraping and re-rolling path. When the main factor of post-control recurrence is the main cause of compaction recurrence, a new control measurement point sequence is generated based on the post-control re-rolling residual sequence, and the construction parameter control path is set to the harrowing, re-mixing, and re-rolling path. When the main factor of the post-control return is the jetting time distance, a new control measurement point sequence is generated based on the post-control re-rolling residual sequence, and the construction parameter control path is set as the jetting time distance reset re-mixing and re-rolling path.

[0036] In this embodiment, after the construction parameter control path of the current construction unit has been determined, the operation control of the current construction unit is performed according to the current construction parameter control path. After the operation control is completed, the elevation after re-rolling is re-collected. The re-rolling elevation sequence is generated by arranging the measuring points according to the measuring point number, measuring point mileage, and measuring point lateral position in the measuring point sequence. Then, using the loose paving benchmark elevation sequence as the deduction benchmark, the residual calculation is performed on each item of the re-rolling elevation sequence to generate the re-rolling residual sequence. For example, in the construction of the polymer composite stabilized soil beam yard base course of the construction access road in Dingtao beam yard, if the recurrence principal factor obtained from the previous judgment is the main cause of the shaping residual, the site can be constructed according to the cross-scraping re-rolling path. For the control point sequence, the first control point should be cross-scraped and leveled before re-rolling. After re-rolling, the elevation after re-rolling should be remeasured. If the main factor of recurrence obtained from the previous judgment is the main cause of compaction recurrence, the control point sequence with large residual amplitude can be loosened, remixed, and re-rolled around the control point sequence according to the loosening and re-mixing re-rolling path. After re-rolling, the control re-rolling elevation sequence and control re-rolling residual sequence should be generated. If the main factor of recurrence obtained from the previous judgment is the main cause of spraying time, the control re-mixing and re-rolling path can be reset according to the spraying time. The end time of composite stabilizer spraying and the end time of re-rolling should be re-recorded, and then re-mixing and re-rolling should be performed according to the control point sequence as the order of operation points. Subsequently, the initial rolling residual sequence, the leveling residual sequence, and the controlled re-rolling residual sequence are combined to form a controlled three-phase residual sequence. Iterative analysis is then performed based on this controlled three-phase residual sequence to generate the controlled return principal factor. When the controlled return principal factor is the stable shaping principal factor, the current construction parameter control path is maintained, and new leveling, rake loosening, remixing, and spraying time interval adjustment commands are stopped for the current construction unit, allowing the current construction unit to enter the post-re-rolling curing phase. When the controlled return principal factor is the shaping residual principal factor, based on... A new control point sequence is generated based on the post-re-rolling residual sequence, and the construction parameter control path is set to the cross-scraping re-rolling path. When the post-returning principal factor is the compaction return principal factor, a new control point sequence is generated based on the post-re-rolling residual sequence, and the construction parameter control path is set to the loosening and re-mixing re-rolling path. When the post-returning principal factor is the spraying time distance principal factor, a new control point sequence is generated based on the post-re-rolling residual sequence, and the construction parameter control path is set to the spraying time distance reset and re-mixing re-rolling path. Through the above implementation method, the construction parameter control path, post-re-rolling elevation, post-re-rolling elevation sequence, loose paving reference elevation sequence, post-re-rolling residual sequence, post-three-phase residual sequence, and post-returning principal factor are connected into a closed-loop construction control process. The purpose is to verify whether the previous operation control has brought the current construction unit into a stable forming state, and if it has not yet entered a stable forming state, to continue generating a new control point sequence and a new construction parameter control path based on the post-re-rolling residual sequence.Compared to the current method of relying solely on manual observation, elevation sampling, or experience-based rework after re-rolling, this method incorporates the post-control measurement results into the analysis of the three construction phases: initial rolling, leveling, and post-control re-rolling. This transforms the construction of the polymer composite stabilized soil beam base course from a single-stage process to an iterative one. In actual construction, when concentrated fluctuations in the post-control re-rolling residual sequence still occur at the joints after cross-leveling and re-rolling, the current method can continue to set the construction parameter control path as the cross-leveling and re-rolling path. When the fluctuations turn into compaction recurrence characteristics, the method can switch to the rake-loosening-remixing and re-rolling path. This ensures that the on-site actions such as leveling, rake-loosening, remixing, spraying time interval reset, re-rolling, and curing are consistent with the post-control recurrence master factor, achieving the goal of controlling repeated elevation recurrence, compaction state fluctuations, and abnormal continuation of spraying time intervals.
