Description

Technical Field

[0001] The invention relates to the technical field of caisson construction, and in particular to a deviation-correcting construction method for a large-scale pressed-in rectangular caisson structure. Background Art

[0002] In the existing open-cut underground structure construction, we often face the risk of pressurized water surge resistance in deep foundation pit excavation, the abandonment of a large number of supporting structures, the low level of construction intelligence, and the difficulty in controlling the impact on the surrounding environment. In order to meet these challenges, the engineering community is considering converting multi-scenario deep foundation pit projects, such as underground rail transit stations, bank sections of cross-river tunnels, and underground integrated pipeline corridors, into caisson projects using large rectangular caissons (length-to-width ratio ≥ 1.5). Although the domestic single-type caisson technology is quite mature and is mainly used for single underground structures with a relaxed surrounding environment, its traditional correction methods, such as uneven soil extraction in the well and high-point loading, although simple and practical, have obvious deficiencies in accuracy, mechanization, and intelligence, and the correction has a lag.

[0003] Therefore, a large-scale pressed-in rectangular caisson structure deviation correction construction method is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The present invention aims to provide a deviation correction construction method for a large-scale pressed-in rectangular caisson structure, so as to solve or improve at least one of the above-mentioned technical problems.

[0005] In view of this, a first aspect of the present invention is to provide a deviation correction construction method for a large-scale pressed-in rectangular caisson structure.

[0006] A second aspect of the present invention is to provide a system.

[0007] The first aspect of the present invention provides a large-scale press-in rectangular caisson structure correction construction method, comprising the following steps: setting a plurality of monitoring points on the two long sides of the rectangular caisson; configuring a side sinking channel according to the circumferential shape of the rectangular caisson, and continuously sinking the rectangular caisson into the interior of the side sinking channel along an extension direction; during the sinking process, obtaining the elevation value between each of the monitoring points and the port of the side sinking channel in real time; judging whether the rectangular caisson needs correction at the current moment according to the difference in the elevation values; when the rectangular caisson needs correction, drawing elevation curves of the two long sides respectively according to the elevation values ​​at the current moment; determining the adjustment amount required for correcting the rectangular caisson according to the elevation curve, and adjusting the postures of the two long sides according to the adjustment amount until the two long sides correctly correspond to the ports along the extension direction; during the correction process, updating the elevation curve in real time.

[0008] In any of the above technical solutions, the posture adjustment path of the rectangular caisson is a multi-segment path composed of multiple nodes connected in sequence from the adjustment starting point to the adjustment end point; a posture feature for judging whether the current rectangular caisson is qualified is set at each node.

[0009] In any of the above technical solutions, in the judgment of the posture feature, each long side and short side of the rectangular caisson is set to a rigid state, or the rectangular caisson is set to a rigid state.

[0010] In any of the above technical solutions, the nodes on the posture adjustment path are respectively a first node set with a parallel posture, a second node set with an equal height posture and a third node set with an equal horizontal posture, and all the posture features are judged by the elevation curve; the horizontal coordinate of the elevation curve is the horizontal distance between each monitoring point and one end of the long side where it is located, and the vertical coordinate of the elevation curve is the elevation value of each monitoring point relative to the port.

[0011] In any of the above technical solutions, between the first node and the second node, the long side portion is set to a rigid body state, and the correction step of the rectangular caisson includes: obtaining the slopes of the elevation curves of the two long sides and the first elevation difference between the corresponding monitoring points along the longitudinal direction; using the monitoring point with the smallest first elevation difference as a reference point to adjust the long side portion until the slopes of the two elevation curves are the same to meet the parallel posture.

[0012] In any of the above technical solutions, the step of adjusting the long side parts by using the monitoring point with the smallest first elevation difference as a reference includes: judging whether the inclination directions of the two long side parts are the same through the slope; if the inclination directions are the same, drawing a relative elevation curve between the two long side parts through the elevation value of each monitoring point, taking the difference between the first elevation difference of the reference point and the first elevation difference of the other monitoring points as the correction height difference, adjusting the long side part with the larger slope value until the inclination angle of the relative elevation curve is zero; if the inclination directions are different, taking the difference between the first elevation difference of the reference point and the first elevation difference of the other monitoring points as the correction height difference, adjusting the two long side parts respectively until the slopes of the two elevation curves are zero.

[0013] In any of the above technical solutions, between the second node and the third node, the long side portion and the short side portion are set to a rigid body state, and the correction step of the rectangular caisson also includes: obtaining the second elevation difference between the corresponding monitoring points along the longitudinal direction, and calculating the absolute value of the elevation between the two long side portions through all the second elevation differences; using the absolute value of the elevation as the correction height difference to adjust one of the long side portions until the two elevation curves coincide to meet the contour posture.

[0014] In any of the above technical solutions, between the third node and the adjustment end point, the rectangular caisson is set to a rigid body state, and the correction step of the rectangular caisson also includes: taking the corresponding monitoring points along the longitudinal direction as a group; determining the third elevation difference between each group of the monitoring points and one end of the long side through the elevation curve; using the third elevation difference as the correction height difference of the corresponding monitoring point to simultaneously adjust the two long side parts until the third elevation difference of all monitoring points on the elevation curve is zero to meet the equal level posture.

[0015] In any of the above technical solutions, when adjusting the long side parts to respectively conform to the parallel posture, the equal height posture and the equal level posture, the correction load for adjusting the long side parts at each of the monitoring points is calculated by the following formula: Fij=Kij×△sj; wherein, Fij is the correction load required to be applied to the jth monitoring point of the ith long side part, and i=(1, 2), j=(1, 2, 3...n), n is the number of the monitoring points; Kij is the equivalent bed stiffness of the jth monitoring point of the ith long side part; △sj is the correction height difference required for the adjustment of the jth monitoring point of the ith long side part.

[0016] A second aspect of the present invention provides a system, comprising sensors arranged at the monitoring points, and reaction piles arranged between the outer wall of the long side portion and the inner wall of the side sinking channel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The caisson structure has been made more suitable for complex and demanding engineering scenarios, such as underground rail transit stations, urban underground road tunnels, and underground comprehensive pipeline galleries. It has not only improved the accuracy of the caisson construction method, but also expanded its application potential in deep foundation pit projects. By controlling the posture and position of the caisson, it can ensure that the caisson can be carried out safely and efficiently in these complex environments, while maximizing the use of underground space.

[0019] Compared with traditional loading correction methods, it can capture any slight deviation of the caisson in real time and make immediate adjustments, greatly reducing the reliance on manual intervention, thereby saving a lot of labor costs. It not only improves the response speed and accuracy of correction, but also makes the entire caisson process more economical and efficient.

[0020] By adjusting the sinking posture of the caisson in real time, the posture can be continuously adjusted throughout the caisson process, reducing the difficulty and magnitude of a single correction. This gradual and gentle correction method reduces the impact of construction on the surrounding environment, effectively controls the adverse effects that caisson construction may have on surrounding buildings and geological structures, and can be implemented in densely built environments in cities, reduce existing infrastructure, and reduce environmental disturbances during construction.

DETAILED DESCRIPTION

[0037] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0039] See also Figure 1-Figure 12 , the following describes a large-scale press-in rectangular caisson structure correction construction method according to some embodiments of the present invention.

[0040] The embodiment of the first aspect of the present invention provides a large-scale press-in rectangular caisson structure deviation correction construction method. In some embodiments of the present invention, such as Figure 1-Figure 11 As shown, the caisson structure deviation correction construction method includes the following steps:

[0041] S101, multiple monitoring points 6 are set on two long sides of the rectangular caisson; a side sinking channel is configured according to the circumferential shape of the rectangular caisson, and the rectangular caisson is continuously sunk into the inside of the side sinking channel along an extension direction.

[0042] Here, monitoring point 6 is responsible for collecting key data such as the inclination, horizontal deviation and speed of the caisson during the sinking process in real time, ensuring that the caisson maintains the correct posture during the sinking process. The data collected from these monitoring points 6 provide real-time feedback to the construction team, helping them to evaluate the status of the caisson and make necessary adjustments; the side sinking channel is designed according to the specific circumferential shape of the caisson to ensure that the caisson can proceed smoothly during the sinking process and reduce the resistance and damage caused by shape mismatch. The design of the channel takes into account reducing the friction between the caisson and the soil, making the sinking process smoother; continuous sinking operations ensure the smoothness and continuity of the caisson process, avoid instability and potential risks caused by stopping and starting, and perform sinking operations along a specific extension direction to ensure that the caisson sinks accurately to the target position according to the predetermined trajectory.

[0043] From the above, it can be seen that the data from monitoring point 6 is used to evaluate whether posture adjustment is needed, so as to guide the construction team to perform effective correction operations. The real-time feedback of the monitoring data enables the operation team to respond quickly and adjust the specific operations in the caisson process, such as adjusting the weight distribution or using mechanical equipment for pushing and pulling; the channel design needs to work closely with the data from monitoring point 6 to ensure that the caisson maintains the correct path and posture throughout the sinking process. If the side sinking channel is properly designed, the number and degree of correction required during the caisson process can be greatly reduced; the control of the continuous sinking process depends on the data provided by monitoring point 6. These data help adjust the caisson speed and direction to cope with possible deviations or tilts. The continuous sinking needs to be closely coordinated with the design of the side sinking channel to ensure that the caisson does not deviate from the predetermined path during the entire sinking process.

[0044] In any of the above embodiments, the rectangular caisson includes a first caisson wall 1 and a second caisson wall 2 as long sides and corresponding to each other in the longitudinal direction; between the first caisson wall 1 and the second caisson wall 2, the rectangular caisson also includes two third caisson walls 3 as short sides and corresponding to each other in the transverse direction, and the first caisson wall 1, the second caisson wall 2 and the third caisson wall 3 are circumferentially connected and enclosed.

[0045] In this embodiment, the two shaft walls serve as the main supporting structure of the caisson, and are arranged along the longitudinal direction of the caisson, providing the main structural strength and rigidity. They are usually longer and can withstand more soil and water pressure. The first caisson wall 1 and the second caisson wall 2 are parallel to each other, ensuring the symmetry and balance of the caisson in the longitudinal direction. During the sinking process, this arrangement helps to disperse the pressure borne by the caisson and reduce possible structural deformation; located on the two short sides of the caisson, these shaft walls connect the first caisson wall 1 and the second caisson wall 2 on the long side to complete the circumferential closure of the caisson and form a stable rectangular frame. They provide additional lateral support to help maintain the overall geometric shape. The connection between the third caisson wall 3 and the long side wall is the key to the stability of the caisson structure. Through this connection method, the caisson can withstand greater soil and water pressure in the lateral direction without deformation.

[0046] In any of the above embodiments, a gap is formed longitudinally between the rectangular caisson and the side caisson channel, and reaction piles 8 for applying correction loads to the first caisson wall 1 and the second caisson wall 2 are placed inside the gap, and the points between the first caisson wall 1 and the second caisson wall 2 and the reaction piles 8 are used as correction points 7; a correction pressure buried part 10 connected to the reaction piles 8 by a correction cable 11 is installed on the outside of the rectangular caisson.

[0047] In this embodiment, reaction piles 8 are installed in the gap formed between the rectangular caisson and the side sinking channel. These reaction piles 8 are used to apply the correction load. These piles can adjust the position of the caisson by providing a reverse force according to the actual deviation during the sinking process of the caisson, thereby correcting the deviation; the position and number of the reaction piles 8 are designed according to the specific size of the caisson and the expected deviation risk. They are directly related to the structural strength of the caisson and the adjustment of the sinking trajectory to ensure the effective transmission of the correction force.

[0048] The correction points 7 on the first caisson wall 1 and the second caisson wall 2 are the specific locations where the reaction piles 8 apply force. By applying force at these points, the posture of the caisson can be most effectively adjusted to achieve the purpose of correction; the selection of the correction points 7 is usually based on structural engineering analysis to determine at which positions the correction force is most effective. The setting of these points ensures that the correction force can directly act on the key structural parts of the caisson to achieve the best correction effect.

[0049] The correction cable 11 connects the reaction pile 8 to the correction pressure buried part 10 outside the caisson. This arrangement uses the tension of the cable to transmit the correction force, so that the caisson can be effectively adjusted in position. The correction pressure buried part 10 serves as an anchor point to ensure the stability of the cable and the continuous effect of the correction force; the design of the cable and the pressure buried part needs to take into account the stability and response speed of the overall correction system. The position and weight of the pressure buried part have a direct impact on the effect of the correction system and must match the size, weight and expected sinking depth of the caisson.

[0050] In any of the above embodiments, within the interior circumferentially enclosed by the first caisson wall 1, the second caisson wall 2 and the third caisson wall 3, the rectangular caisson also includes an inner caisson partition wall 4 for supporting the first caisson wall 1, the second caisson wall 2 and the third caisson, and the inner caisson partition walls 4 are fixed by frame columns 5, and a plurality of frame beam plates 12 are installed on the frame columns 5 along the extension direction.

[0051] In this embodiment, the partition wall 4 in the well is used to support the first caisson wall 1, the second caisson wall 2 and the third caisson wall 3, and enhance the structural stability of the entire caisson. The partition wall not only helps to disperse the force from the soil and water pressure, but also divides the internal space of the caisson for different functions and service areas; the existence of the partition wall makes the main structure of the caisson more solid and reduces the deformation of the wall caused by external pressure. At the same time, the partition wall also provides an additional waterproof layer, enhancing the anti-seepage property of the caisson.

[0052] The frame columns 5 fix and connect the partition walls 4 in the well to provide vertical support. These columns constitute the main load-bearing structure inside the caisson, supporting the beams and slabs above and the top structure of the caisson; the arrangement of the frame columns 5 is directly related to the load-bearing capacity of the caisson and its stability against external environmental influences. By effectively connecting the partition walls, the frame columns 5 help form a solid three-dimensional support network, enhancing the overall stability of the structure.

[0053] The frame beam slab 12 is installed on the frame column 5 and distributed along the extension direction to connect different frame columns 5 and disperse the load of the upper structure. The beam slab also helps to evenly distribute the pressure from the top or internal live load (such as equipment operation, personnel activities, etc.); the design and layout of the frame beam slab 12 are closely related to the stability of the frame column 5 and the partition wall 4 in the well. The strength and layout of the beam slab determine how the upper load is transmitted to the entire caisson structure.

[0054] Furthermore, cutting feet 9 are provided on the end portions of the side walls of the first caisson wall 1 , the second caisson wall 2 and the third caisson wall 3 facing the frame column 5 .

[0055] As can be seen from the above, the blade foot 9 is mainly used to cut the soil to help the caisson sink to the predetermined position more smoothly. During the sinking process of the caisson, the blade foot 9 plays a leading role, cutting the soil layer that hinders the sinking and reducing the soil resistance encountered by the caisson during the sinking process; the design and position of the blade foot 9 directly affect the efficiency and safety of the caisson sinking. By connecting with the frame column 5, the strength and stability of the blade foot 9 are enhanced, which helps to maintain the integrity and alignment of the entire caisson structure during the sinking process.

[0056] S102, during the sinking process, the elevation value between each monitoring point 6 and the port of the side sinking channel is obtained in real time; according to the difference in the elevation values ​​between the monitoring points 6, it is determined whether the rectangular caisson needs to be corrected at the current moment.

[0057] Here, monitoring point 6 is installed at a key position of the caisson to collect elevation values ​​in real time with respect to the port of the side channel. This data provides accurate vertical and horizontal position information of the caisson; the port of the side channel serves as a reference point to help determine the alignment of the caisson with the intended path. This is a key criterion for assessing the correctness of the caisson position; by calculating the difference in elevation values ​​between monitoring points 6, the degree of horizontal or vertical deviation of the caisson can be determined. This difference analysis is the basis for corrective decision-making and helps determine the stability and alignment of the caisson at any given moment.

[0058] As can be seen from the above, the data from monitoring point 6 is directly used to evaluate the posture and position of the caisson. The key is to monitor in real time whether the caisson is tilted or offset, so as to determine whether a correction operation is needed; the fixed position of the port provides a static reference for comparison with the dynamically changing caisson position to evaluate the accuracy of the caisson sinking and the direction that needs to be adjusted; the analysis of the elevation difference directly affects the formulation of the correction strategy. If the elevation difference exceeds the preset allowable range, it indicates that the caisson needs to be adjusted through correction measures to ensure its safety and functional integrity.

[0059] In any of the above embodiments, the monitoring point 6 is pre-buried in the same horizontal plane of the first caisson wall 1 and the second caisson wall 2. If the rectangular caisson needs to be raised multiple times, the monitoring point 6 should be set in the first pouring of the caisson structure.

[0060] In this embodiment, the monitoring points 6 are usually pre-buried in the same horizontal plane of the first caisson wall 1 and the second caisson wall 2 of the caisson, and are used to monitor the position and posture of the caisson in real time. These monitoring points 6 can collect data on the horizontal and vertical movement, tilt angle and other key parameters of the caisson; by pre-buried monitoring points 6 in the same horizontal plane, it can be ensured that the collected data is spatially consistent, which is convenient for accurate analysis. This layout helps to achieve accurate monitoring and control of the overall posture of the caisson.

[0061] In the case where the caisson structure needs to be raised multiple times, the monitoring point 6 should be set in the first cast caisson structure. The purpose of this is to ensure the continuity and stability of the monitoring system, because the first cast structure is usually the foundation of the entire caisson and has higher stability and reliability; setting the monitoring point 6 in the foundation structure of the caisson can ensure that the monitoring equipment can remain fixed and function unaffected even during the heightening process, which helps to maintain accurate monitoring throughout the construction process.

[0062] Specifically, the aspect ratio of the rectangular caisson is ≥1.5, specifically, the first caisson wall 1 or the second caisson wall 2 and the third caisson wall 3 are as follows: Figure 2 The ratio of the length in the plane of Figure 2 The normal direction of the plane.

[0063] As can be seen from the above, the aspect ratio is defined as the ratio of the length of the first caisson wall 1 or the second caisson wall 2 to the length of the third caisson wall 3. A high aspect ratio (≥1.5) means that the length of the caisson is significantly greater than its width. This design is usually used to improve the longitudinal stability of the structure and reduce the risk of tilting in the horizontal direction; caissons with higher aspect ratios are more stable in the longitudinal direction, which helps to sink more smoothly under uneven geological conditions. At the same time, this design also helps to achieve higher depth penetration within a limited lateral space, especially in urban areas or other space-constrained environments.

[0064] In any of the above embodiments, Figure 3 As shown, the extension direction is perpendicular to the port ground line 14 of the side sinking channel. When the sinking is completed, the ends of the first caisson wall 1, the second caisson wall 2 and the third caisson wall 3 with the blade feet 9 pass through the pit bottom line 13 of the side sinking channel.

[0065] In this embodiment, the blade foot 9 is usually located at the end of the caisson wall, and its main function is to help cut the soil and other underground materials and reduce the physical resistance encountered by the caisson during the sinking process. By providing an effective cutting action, the blade foot 9 enables the caisson to penetrate various strata more smoothly, especially in hard soil or gravel layers; the design and position of the blade foot 9 are directly related to the efficiency and safety of the caisson sinking. The size, shape and material selection of the blade foot 9 need to match the overall design of the caisson and the expected geological conditions to ensure maximum functional efficiency and durability.

[0066] The end of the caisson wall, especially the end with the blade foot 9, not only supports the entire caisson structure, but also directly participates in the cutting action, penetrating the ground into deeper soil; the end design of the caisson wall needs to consider the coordination with the bottom line 13 of the side sinking channel pit to ensure that the structural integrity and operation continuity can be maintained when penetrating the bottom line 13 of the side sinking channel pit.

[0067] The bottom line 13 of the side sinking channel is the final target line that the caisson sinks to, and its setting is based on the predetermined caisson depth and position. The caisson needs to accurately pass through this bottom line 13 to ensure that the caisson is correctly installed in its final position; the design of the side sinking channel needs to be closely coordinated with the design of the caisson wall and the blade foot 9 to ensure the smooth progress and structural safety of the caisson when passing through the bottom line 13.

[0068] Furthermore, when it is determined at each moment that the rectangular caisson needs to be corrected, the initial values ​​of each monitoring point 6 are obtained, the initial average elevation H0 is taken, and the four-corner elevation difference limit s0 is set. During the sinking process, the elevation of the measuring point is monitored in real time; when the maximum value of the four-corner elevation difference δ>s0, the correction is started.

[0069] S103, when the rectangular caisson needs to be corrected, the elevation curves of the two long sides are drawn respectively according to the elevation values ​​at the current moment; the adjustment amount required for correcting the rectangular caisson is determined according to the elevation curves, and the postures of the two long sides are adjusted according to the adjustment amount until the two long sides correctly correspond to the ports along the extension direction.

[0070] Here, the elevation curves are drawn based on the elevation value of monitoring point 6 at the current moment. These curves show the change in the position of the two long sides of the caisson over time. Through these curves, the construction team can intuitively observe the real-time posture of the caisson and any potential tilt or offset; based on the elevation curves, the construction team can determine the specific adjustments required for each part of the caisson. These adjustments are based on the difference in elevation between the two sides, and determine the measures that need to be taken to correct the posture of the caisson and return it to the predetermined correct position; the posture of the two long sides of the caisson is adjusted by mechanical adjustment or changes in weight distribution. These adjustments help correct the horizontal or vertical tilt of the caisson and ensure that each side correctly corresponds to the port of the side sinking channel.

[0071] As can be seen above, the elevation curve enables the construction team to quickly identify the specific location and extent of the deviation, which is the basis for effective correction. The data provided by the curve directly affects the subsequent correction strategy and adjustment decisions; the determination of the adjustment amount is a precise calculation process that needs to take into account the data changes in the elevation curve, as well as the physical and mechanical characteristics of the caisson structure. These calculations directly affect the accuracy and effectiveness of the correction operation; the adjustment of the posture needs to work closely with the real-time monitoring system and the elevation curve to ensure that the adjustment action can accurately respond to the observed deviation. In addition, the adjustment process may require multiple iterations to carefully achieve the optimal posture alignment.

[0072] Specifically, the correct correspondence is characterized in that the long side portion is always parallel to the plane of the port during movement.

[0073] In any of the above embodiments, the posture adjustment path of the rectangular caisson is a multi-segment path composed of multiple nodes connected in sequence from the adjustment starting point to the adjustment end point. The posture adjustment path is a moving path for adjustment when the rectangular caisson needs to be corrected, and is independent of the sinking path of the rectangular caisson; posture features are set at each node to determine whether the current rectangular caisson is qualified.

[0074] In this embodiment, the posture adjustment path defines the movement path of the caisson from the adjustment start point to the adjustment end point. This path is connected by multiple nodes in sequence to form a multi-segment path. This path is specifically used for correction adjustment during the caisson caisson process and is independent of the main sinking path of the caisson. This independent adjustment path allows the construction team to make precise position and posture adjustments without affecting the main sinking process, thereby ensuring that the caisson can be accurately aligned and stably sunk to the predetermined position.

[0075] At each node, posture features are set to determine whether the current rectangular caisson is qualified. These features may include the caisson's tilt angle, horizontal position deviation, structural stress, etc. Each feature is a standard for judging whether the current state of the caisson meets the engineering requirements; setting specific posture features at each node allows the construction team to accurately evaluate the state and make necessary adjustments at each key point of the path. This method ensures the continuity and systematicness of the entire correction process and improves the accuracy and efficiency of the adjustment.

[0076] In any of the above embodiments, in the judgment of the posture feature, each long side portion and short side portion of the rectangular caisson is set to a rigid state, or the rectangular caisson is set to a rigid state.

[0077] In this embodiment, setting each long side and short side of the caisson as a rigid body in posture judgment means that these parts are considered to be solid blocks without elastic deformation during calculation and simulation. This assumption allows the construction team to analyze and predict the behavior of the caisson through a more simplified physical model, especially when dealing with complex mechanical problems; this rigid body assumption allows the elastic deformation of the material to be ignored during mechanical analysis and correction operations, focusing on the overall balance and alignment. This simplifies the calculation process and makes decisions faster and more accurate.

[0078] The entire rectangular caisson is set as a rigid body, and its overall movement and rotation as a single block are considered in the calculation of attitude adjustment. This assumption helps to evaluate the overall response of the caisson when it is affected by non-uniform foundations; the setting of the overall rigid body allows the construction team to use a simplified mechanical model to predict and implement necessary adjustments when considering the caisson's correction strategy, such as by adjusting the center of gravity or applying external forces.

[0079] In any of the above embodiments, the nodes on the posture adjustment path are respectively a first node set with a parallel posture, a second node set with an equal height posture, and a third node set with an equal level posture, and all posture features are determined by the elevation curve. Among them, the parallel posture represents that the projections of the two long sides along the longitudinal direction are parallel, the equal height posture represents that the projections of the two long sides along the longitudinal direction are coincident, and the equal level posture represents that the projections of the two long sides along the longitudinal direction are parallel to the plane of the port.

[0080] The abscissa of the elevation curve is the horizontal distance between each monitoring point 6 and one end of the long side where it is located, and the ordinate of the elevation curve is the elevation value of each monitoring point 6 relative to the port.

[0081] In this embodiment, the parallel posture requirement ensures that the projections of the two long sides along the longitudinal direction remain parallel, which helps to maintain the linear stability of the caisson during the sinking process and prevent potential structural stress or collision due to tilting; the parallel posture is maintained by comparing the relative elevations of the long sides on both sides to ensure that they are not rotated or offset relative to each other at any depth.

[0082] The equal-height posture requires that the longitudinal projections of the two long sides coincide, that is, the two sides maintain the same elevation in the vertical direction, ensuring that one side of the caisson does not sink faster than the other side; maintaining the equal-height posture helps ensure the uniformity of the caisson during the sinking process and prevent structural stress and potential tilt problems caused by uneven settlement.

[0083] The level posture requires that the longitudinal projections of the two long sides are parallel to the plane of the port, which helps to ensure that the caisson is fully aligned with the port at the target position, especially for precise docking when approaching the final position; by monitoring and adjusting the level posture, the construction team can accurately control the horizontal alignment of the caisson when approaching the target position, ensuring seamless docking of the caisson with the foundation or other structures.

[0084] The horizontal coordinate of the elevation curve represents the horizontal distance between each monitoring point 6 and one end of the long side where it is located. This distance measurement provides specific location information about the monitoring point 6 along the length of the caisson, allowing the construction team to understand the distribution of each monitoring point 6 on the caisson. This setting enables the elevation data to be directly associated with the physical layout of the caisson, providing the construction team with an intuitive way to observe the elevation changes and potential tilt or offset of various parts of the caisson; the vertical coordinate of the elevation curve is the elevation value of each monitoring point 6 relative to the port. These elevation values ​​are key data for evaluating whether the caisson is in the correct position and posture, and are also the basis for determining whether posture adjustments are needed. By combining the elevation value with the horizontal distance, the construction team can understand in detail the elevation distribution of the caisson along its length. If the elevation value of a part of the caisson is abnormal, this may indicate that the caisson is tilted or offset in that area and needs to be corrected.

[0085] Specifically, between the first node and the second node, the long side is set to a rigid state, and the correction steps of the rectangular caisson include:

[0086] The slopes of the elevation curves of the two long sides and the first elevation difference between the corresponding monitoring points 6 along the longitudinal direction are obtained.

[0087] The monitoring point 6 with the smallest first elevation difference is used as a reference point to adjust the long side until the slopes of the two elevation curves are the same to meet the parallel posture.

[0088] In view of the above specific description, setting the long side parts to a rigid body state means that during the correction process, these parts are regarded as a single structure that does not deform. This setting simplifies the calculation model, so that the correction strategy focuses on position and angle adjustment rather than material stress or deformation response; the rigid body state ensures the calculation accuracy and simplicity of construction operation during correction, allowing the construction team to directly adjust the position and angle of the caisson without considering the complex stress distribution inside the structure.

[0089] By calculating the slope of the elevation curves of the two long sides, the construction team can evaluate the tilt of the caisson. The slope reflects the tilt of the caisson in the longitudinal direction and is a key parameter for determining whether the caisson remains parallel; the comparison of the slopes is a direct method for determining whether the caisson has reached a parallel posture during the correction process. If the two slopes are different, it means that the tilt of the two sides of the caisson is inconsistent and needs to be adjusted.

[0090] By calculating the first elevation difference between the corresponding monitoring points 6 along the longitudinal direction, the construction team can determine the degree of inconsistency in the elevations on both sides of the caisson. The purpose of selecting the monitoring point 6 with the smallest elevation difference as the reference point is to find a relatively stable position from which adjustments can most effectively correct the overall posture; the setting of the reference point is the starting point for the correction adjustment, ensuring that the adjustment starts from the position closest to the ideal state, thereby minimizing the required adjustment range and improving the correction efficiency.

[0091] As can be seen above, through precise slope comparison and adjustment based on elevation difference, this correction process can ensure the precise alignment of the caisson in the horizontal and vertical directions. This not only improves the accuracy of construction, but also optimizes the construction process, reducing rework and delays; accurate posture adjustment ensures the structural safety of the caisson, preventing structural stress concentration and potential structural damage caused by posture errors; effective correction strategies reduce the use of additional materials and mechanical operating time, saving costs and improving resource efficiency.

[0092] Specifically, the steps of adjusting the long side portion using the monitoring point 6 with the minimum first elevation difference as a reference include:

[0093] The slope is used to determine whether the inclination directions of the two long sides are the same.

[0094] If the inclination direction is the same, a relative elevation curve between the two long sides is drawn using the elevation values ​​of each monitoring point 6, and the difference between the first elevation difference of the benchmark point and the first elevation difference of other monitoring points 6 is used as the correction elevation difference, and the long side with the larger slope value is adjusted until the inclination of the relative elevation curve is zero.

[0095] If the inclination directions are different, the difference between the first elevation difference of the reference point and the first elevation difference of other monitoring points 6 is used as the correction elevation difference, and the two long sides are adjusted respectively until the slopes of the two elevation curves are zero.

[0096] In view of the above specific description, slope judgment is used to identify whether the inclination direction of the two long sides is the same, which is the key first step in determining how to correct the deviation. The calculation of the slope reflects the degree and direction of the longitudinal inclination of each part of the caisson; the consistency judgment of the slope helps the construction team determine the overall inclination of the caisson and thus select the most effective correction strategy.

[0097] The relative elevation curves between the two long sides are drawn using the elevation values ​​of each monitoring point 6. These curves show the relative positions of the two sides of the caisson in the vertical direction and are an intuitive basis for the deviation correction operation; the relative elevation curves directly guide the deviation correction operation. By comparing the elevation differences of different monitoring points 6, the construction team can accurately adjust the posture of the caisson to ensure the balance of both sides.

[0098] The correction height difference is calculated based on the difference in the first elevation difference between the benchmark point and the other monitoring points 6, and this height difference determines the amount of adjustment required. The purpose of the adjustment is to make the inclination of the long side with a larger slope value zero, or to make the slopes of the two elevation curves zero; the calculation of the correction height difference is based on the actual measured elevation difference, ensuring the accuracy of the adjustment measures. This method allows the construction team to make targeted adjustments based on specific tilt conditions and optimize the overall posture of the caisson.

[0099] From the above, we can see that through the systematic slope analysis and elevation adjustment, this correction process significantly improves the accuracy of caisson sinking, ensuring that the caisson sinks to the target depth in the correct position and posture; precise posture control reduces the structural stress and potential risks that may be caused by excessive tilt, and improves construction safety; effective correction operations reduce the number of repeated adjustments required, saving time and resources, thereby controlling project costs.

[0100] Specifically, the first stage of deviation correction is "parallelization first":

[0101] The horizontal distance between each correction point 7 and the left end of the caisson is (X1, X2, X3, ..., Xn-2, Xn-1, Xn), the elevations of each point on the two walls along the long sides are (h11, h12, h13, ..., h1n-2, h1n-1, h1n), (h21, h22, h23, ..., h2n-2, h2n-1, h2n), and the inclination angles of the elevation curves of the two walls are α and β respectively.

[0102] If the two walls have the same inclination direction, determine the inclination difference (α-β) between the two walls and the equal-elevation point X0 according to the elevation curve to draw the relative elevation curve. For the high point of the wall corresponding to the large inclination angle (i.e. [0, X0] or [X0, Xn]), load the correction point 7 until the two elevation curves are parallel. The loading point correction load Fij=Kij×△sj, where i=(1,2), j=(1,2,3...n).

[0103] If the two walls are inclined in opposite directions, adjust the inclination angles of the two walls to 0° twice according to the above processing principles.

[0104] Specifically, between the second node and the third node, the long side and the short side are set to a rigid body state, and the deviation correction step of the rectangular caisson also includes:

[0105] The second elevation difference between the corresponding monitoring points 6 along the longitudinal direction is obtained, and the absolute value of the elevation between the two long side parts is calculated through all the second elevation differences.

[0106] Use the absolute value of the elevation as the correction height difference to adjust one of the long sides until the two elevation curves overlap to meet the same height posture.

[0107] In view of the above specific description, the long and short sides are set to a rigid state during the correction process, which means that these parts are considered to have no deformation during the operation. This setting simplifies the mechanical calculation, allowing the correction operation to focus on adjusting the position rather than dealing with structural deformation; the setting of the rigid state ensures that the calculation and implementation of the adjustment during the correction process is more direct and simple, reducing the uncertainty caused by structural complexity.

[0108] Obtain the second elevation difference between the corresponding monitoring points 6 along the longitudinal direction, which reflects the relative height difference between the two long sides in the vertical direction. This is the basic data for evaluating and implementing deviation correction; the calculation of the second elevation difference provides an accurate quantitative basis for deviation correction, so that adjustment measures can be targeted to reduce elevation differences and further optimize the vertical alignment of the caisson.

[0109] The absolute value of the elevation between the two long sides is calculated through all the second elevation differences, and this value is used to determine the amount of elevation difference that needs to be adjusted during correction. The absolute value of the elevation is a direct indicator of the amount of correction adjustment, indicating the specific adjustment height required to achieve the equal height posture; the absolute value of the elevation is used as the correction height difference for adjustment until the two elevation curves coincide, which ensures that the caisson reaches a completely equal height state in the longitudinal direction, that is, there is no height difference, and the equal height posture meets the design requirements.

[0110] From the above, we can see that accurate elevation difference measurement and the correction operation based on it ensure the perfect alignment of the caisson in the vertical direction, greatly improving the accuracy of construction; by ensuring the equal height posture of the caisson, structural stress and potential damage caused by tilt can be effectively prevented, enhancing the overall structural safety; effective and accurate correction steps reduce the subsequent adjustments and rework that may be required, saving time and cost, and optimizing resource utilization.

[0111] Specifically, the second stage of correction is “re-heightening”:

[0112] After the first correction stage, the inclination angles of the two walls are consistent, but the average elevations of the walls are still different, such as elevation curve 1' and elevation curve 2'. Therefore, in this stage, the wall correction point 7 with a small absolute value of the average elevation is uniformly pressurized until the average elevations are the same. The loading point correction load Fij = Kij × △s, where i = (1, 2), j = (1, 2, 3...n).

[0113] Specifically, between the third node and the adjustment end point, the rectangular caisson is set to a rigid body state, and the correction steps of the rectangular caisson also include:

[0114] The corresponding monitoring points 6 along the longitudinal direction are taken as a group.

[0115] The third elevation difference between each group of monitoring points 6 and one end of the long side is determined by the elevation curve.

[0116] The third elevation difference is used as the correction elevation difference of the corresponding monitoring point 6, and the two long sides are adjusted at the same time until the third elevation difference of all monitoring points 6 on the elevation curve is zero to meet the equal level posture.

[0117] In view of the above specific description, the rectangular caisson is set to a rigid body state, which means that when performing the correction operation, each part of the caisson is regarded as a solid that does not deform. This assumption simplifies the correction calculation, so that the focus is on adjusting the overall position and angle of the caisson; this setting ensures the simplicity and directness of the correction operation, because there is no need to consider the deformation caused by structural elasticity or complex internal mechanical reactions.

[0118] By grouping the corresponding monitoring points 6 along the longitudinal direction, the elevation data can be systematically organized and analyzed. This grouping helps to effectively manage and compare the elevation differences between different points at the same longitudinal position. By grouping the monitoring points 6, the correction operation can be carried out in a more targeted and efficient manner. The data of each group of monitoring points 6 provides detailed information about the relative horizontal position of that part of the caisson.

[0119] The third elevation difference between each group of monitoring points 6 and one end of the long side is determined by the elevation curve. This difference is used to identify and measure the deviation between the current posture of the caisson and the ideal horizontal state; the third elevation difference is the direct basis for implementing the correction operation, providing the necessary data support to adjust the caisson so that the elevation difference of all monitoring points 6 reaches zero, that is, to ensure the horizontal alignment of the caisson.

[0120] From the above, we can see that by accurately measuring and adjusting the third elevation difference, this correction step ensures the horizontal alignment of the caisson, thereby significantly improving the accuracy and efficiency of construction; ensuring the horizontal alignment of all parts of the caisson can effectively prevent structural stress and potential damage caused by improper posture, thereby improving the stability and safety of the overall structure; through effective monitoring and adjustment strategies, the need for repeated adjustments is reduced, saving costs and time, and improving the efficiency of resource utilization.

[0121] Specifically, the third stage of correction is "post-leveling":

[0122] After the above-mentioned correction stage 1 and stage 2, the posture of the long side wall is consistent, and the inclination of the caisson is close to that of a rigid body (elevation curve 1"). Therefore, the ultimate goal of this stage is to level the caisson (rigid body) as a whole, and apply correction loads to the well wall 1 and the well wall 2 at the same time. The loading point correction load Fij = Kij × △sj, where i = (1, 2), j = (1, 2, 3...n).

[0123] In any of the above embodiments, when the long side portion is adjusted to meet the parallel posture, the equal height posture and the equal level posture respectively, the correction load of the long side portion at each monitoring point 6 is calculated by the following formula:

[0124] Fij=Kij×△sj;

[0125] Among them, Fij is the correction load required to be applied to the j-th monitoring point 6 at the i-th long side, and i=(1, 2), j=(1, 2, 3...n), n is the number of monitoring points 6; Kij is the equivalent bed stiffness of the j-th monitoring point 6 at the i-th long side; △sj is the correction height difference required for the adjustment of the j-th monitoring point 6 at the i-th long side.

[0126] In this embodiment, Fij is the corrective load required to be applied to the jth monitoring point 6 of the i-th long side, which is used to adjust the caisson part to a predetermined posture. The accurate calculation and application of this force is one of the most critical steps in the correction process, ensuring the structural stability and accurate position of the caisson; the corrective load directly affects the actual movement and final position of each part of the caisson, ensuring that each part meets the posture required by the design.

[0127] Kij is the equivalent bed stiffness of the jth monitoring point 6 at the i-th long side. This parameter reflects the stiffness of the soil or supporting structure when the caisson is loaded. Bed stiffness is an important factor in calculating the correction load, which affects the amount of force required; the bed stiffness determines the amount of force required to apply under the same height difference. High stiffness indicates that a greater force is required to achieve the same displacement.

[0128] △sj is the correction height difference of the jth monitoring point 6 on the i-th long side, that is, the difference between the elevation of this point and the predetermined elevation. This elevation difference directly determines how much posture adjustment is required; the correction height difference provides a specific adjustment target, and the height difference of each monitoring point 6 guides the calculation of the correction load at the corresponding point to ensure that all monitoring points 6 can eventually reach the same elevation line.

[0129] Specifically, Figure 4 As shown, when the caisson is loaded for correction, it is constrained by the external well wall friction f1, the blade foot 9 end bearing resistance f2, and the internal well wall friction f3. The comprehensive equivalent bed coefficient K can be determined by calculating and combining the data of the well wall and the pre-buried sensor 15 at the bottom of the blade foot 9. Then the corresponding load value during correction loading is taken according to the formula: F = K△s, where △s is the correction height difference. The calculation plane range of the equivalent bed stiffness Kij (function of time t) corresponding to any correction point 7 (such as Pij) is [1 / 2(Xi(j-1)+Xij), 1 / 2(Xi(j+1)+Xij)], where i = (1, 2), j = (1, 2, 3...n).

[0130] S104: During the deviation correction process, the elevation curve is updated in real time.

[0131] Here, real-time updates of elevation curves allow the construction team to continuously monitor the elevation status of the caisson, including any changes caused by uneven soil, uneven loads, or other factors. These curves provide key geographic location data, which is the basis for evaluating the current status of the caisson and planning the next step of operation; real-time updated elevation curves enable the construction team to quickly identify the specific location and extent of the deviation, so as to make targeted adjustments. This dynamic monitoring and adjustment mechanism is the core of accurate deviation correction.

[0132] The sensors 15 or measuring devices at the monitoring point 6 continuously collect data, which are then used to update the elevation curve. Real-time data collection ensures the latest and accuracy of the information obtained; the real-time collection of data at the monitoring point 6 directly affects the update frequency and accuracy of the elevation curve. These data are the prerequisite for effective correction, and the data at any point in time may become the key to adjustment decisions.

[0133] Based on the real-time updated elevation curves, the construction team can implement corrective decisions, which may include adjusting the physical position of the caisson, modifying the support strength or reconfiguring the load; the implementation of corrective decisions depends on accurate and timely elevation data. Real-time updates of the elevation curves provide the necessary information to ensure that each adjustment is based on the best current data.

[0134] As can be seen from the above, the real-time updated elevation curve ensures the timeliness and adaptability of the correction measures, allowing the construction team to respond quickly to any changes, thereby improving the efficiency and success rate of the entire correction process; by continuously monitoring elevation changes, project managers can better control construction risks and prevent possible problems such as uneven settlement or excessive tilt; accurate and timely correction reduces the need for additional adjustments and rework, saves resources and costs, and improves the economic benefits of the overall project.

[0135] The invention provides a large-scale press-in rectangular caisson structure deviation correction construction method, which can monitor the posture and position of the caisson in real time by setting multiple monitoring points 6 at the two long sides of the rectangular caisson and obtaining the elevation values ​​between these monitoring points 6 and the side sinking channel ports in real time. This method improves the real-time and accuracy of monitoring, allowing any potential deviation or tilt to be discovered in a timely manner.

[0136] Elevation curves are drawn using real-time elevation data, and based on these curves, it is determined whether the caisson needs to be corrected. When correction is detected, the required adjustment amount can be accurately calculated and the caisson's posture can be adjusted accordingly until the long side of the caisson is correctly aligned with the port of the side channel. This method significantly improves the accuracy and effectiveness of correction.

[0137] During the correction process, the elevation curve is continuously updated to ensure that the data it is based on is always up to date, thereby ensuring the timeliness and accuracy of the correction measures.

[0138] Through real-time and precise posture adjustment, the present invention reduces structural problems that may be caused by posture errors and enhances the overall safety and reliability of caisson construction; precise correction control and highly automated construction process reduce the impact of improper construction on the surrounding environment, especially construction in cities or other sensitive areas; real-time monitoring and automatic correction reduce the need for rework and shutdown, thereby improving construction efficiency and reducing construction costs; by integrating digital monitoring and automatic adjustment technology, the present invention promotes the modernization and intelligence of caisson construction technology and adapts to the complex needs of modern urban infrastructure construction.

[0139] The embodiment of the second aspect of the present invention provides a system. In some embodiments of the present invention, such as Fig.12As shown, the system includes a sensor 15 arranged at a monitoring point 6, and a reaction pile 8 arranged between the outer wall of the long side and the inner wall of the side sinking channel.

[0140] In order to realize the intelligent deviation correction of the rectangular caisson, the system also includes a monitoring module 16, a control center 17, and a deviation correction power module 18; the monitoring module 16 provides real-time data on the height difference of the four corners of the long side wall of the caisson, and the monitoring data is transmitted to the control center 17, which processes the data and issues a power adjustment instruction to the deviation correction power module 18. The monitoring points 6 and deviation correction points 7 at the four corners of the rectangular caisson are arranged at multiple points along the long side of the rectangular caisson. When the rigid body deflects or the opposite side walls rotate relative to each other during the sinking process of the rectangular caisson, the deviation correction load distribution of each deviation correction point 7 is determined according to the real-time height difference data, and the deviation correction adjustment is carried out in three stages: "parallel first, then equal height, and finally equal level".

[0141] The present invention provides a system in which a sensor 15 is installed at a monitoring point 6 of a rectangular caisson, especially at the four corners of the long side wall, for collecting the height difference data and other relevant structural data of the caisson in real time. The data provided by the sensor 15 is the basis for decision-making in the process of correcting deviation, ensuring that the control center 17 can obtain the real-time status information of the caisson; the reaction pile 8 is arranged between the outer wall of the long side of the caisson and the inner wall of the side sinking channel, for providing necessary support and reaction force to assist in the implementation of the correcting deviation action. The reaction pile 8 plays a key role in the correcting deviation operation, providing physical support for the correction power module 18 to implement force adjustment; the monitoring module 16 collects the data transmitted from the sensor 15, including the real-time height difference data of the four corners of the caisson, etc. These data are very important for evaluating the caisson. The current posture is crucial. The monitoring module 16 transmits the monitoring data to the control center 17 in real time to ensure the fluidity and timeliness of the data and support the formulation of correction decisions; the control center 17 processes the data, analyzes the monitoring data, and issues assistance adjustment instructions to the correction power module 18 based on the data results. The control center 17 is the hub of decision-making. Its data processing and command output directly determine the operating efficiency and accuracy of the correction power module 18; the correction power module 18 receives instructions from the control center 17 and implements specific correction actions, such as adjusting the force of the reaction pile 8, etc., to adjust the posture of the caisson. The correction power module 18 directly acts on the caisson structure, adjusts the position and angle of the caisson according to the instructions of the control center 17, and achieves the correction goal.

[0142] Specifically, the sensor 15 can be a displacement sensor 15 or a tilt sensor 15, the reaction pile 8 is usually a customized product that can be selected according to actual usage requirements, the control center 17 can be a PLC or a data acquisition system, the monitoring module 16 involves a software system that is usually tightly integrated with the hardware, and the correction power module 18 involves a mechanical execution unit.
