Description

Technical Field

[0001] The invention belongs to the technical field of pier construction, and in particular relates to a pier auxiliary device for soft foundation and a deviation correction method. Background Art

[0002] Soft soil exhibits significant adverse engineering properties, with high moisture content and a large porosity, resulting in extremely compressible soil. During existing pier construction, if the pier is installed directly on a soft foundation, the instability of the foundation can cause the pier to tilt. Therefore, prior to pier construction on soft foundations, the soft foundation must be pre-treated to ensure the stability of the subsequent piers and the foundation and superstructure of the upper structures. However, as the service life increases, continuous monitoring and dynamic correction of the soft foundation are required. By acquiring real-time foundation deformation data and making timely adjustments, the long-term stability of pier construction on soft foundations is ensured.

[0003] Related technology (Chinese patent publication number CN113668626B) discloses a method for correcting the deviation of bridge piers on soft soil foundations, including: reinforcing the soft soil foundation by grouting on the inclined side of the bridge pier; drilling stress relief holes on the side opposite to the inclined side of the bridge pier; drilling lifting holes on the expanded foundation of the inclined side of the bridge pier; injecting lifting material along the lifting holes to correct the deviation of the bridge pier; and reinforcing the expanded foundation of the bridge pier by grouting. This method for correcting the deviation of bridge piers involves reinforcing the soft soil foundation by grouting before injecting lifting material to correct the deviation of the bridge pier to increase its bearing capacity; drilling stress relief holes on the side opposite to the inclined side of the bridge pier to reduce deviation in the correction direction, improve correction efficiency, and thus enhance the reliability and accuracy of the bridge pier correction.

[0004] In the above-mentioned prior art, the correction of the soft soil foundation pier column requires manual intervention to complete the excavation and construction operations, which has at least the following defects:

[0005] 1. The pier column lacks autonomous sensing and adaptive adjustment mechanisms when it deflects, making it unable to self-correct in the early stages of deflection;

[0006] 2. Manual monitoring has a lag. If it is not discovered in time, it will easily lead to aggravation of the deviation and increase the difficulty of subsequent correction work;

[0007] 3. Excessive deflection can easily cause irreversible structural damage, resulting in failure of correction or even scrapping of piers, threatening the safety and stability of the project.

[0008] In view of the above defects, a pier auxiliary device for soft foundation and a correction method are proposed to solve the above problems. Summary of the Invention

[0009] In response to the existing problems in the prior art of correcting the deviation of pier columns on soft soil foundations, which require manual intervention to complete excavation and construction operations, lack autonomous perception and adaptive adjustment mechanisms when the pier columns deflect, and are unable to achieve self-correction in the early stages of deflection, the present invention provides a pier column auxiliary device and correction method for soft foundations, which can automatically trigger the opposite side reverse tension mechanism to form a reverse force that counteracts the deflection force, forcing the pier column to achieve force balance in the initial deflection stage and suppress the development of the tilting trend; this adaptive self-correction and self-adjustment mechanism does not require manual intervention, can respond to signs of deflection in real time, and maintain the verticality and stability of the pier column through dynamic force system balance. Its specific technical solutions are as follows:

[0010] A pier auxiliary device for a soft foundation, used for assisting in correcting the deviation of the pier, comprising: a base, a through slot, a collar, and a self-correcting and self-adjusting assembly, wherein the base is vertically arranged at the bottom end of the pier, and the pier is located at the center of the base; a plurality of through slots are provided, and each two through slots form a group symmetrically opened on the base; the collar is fixed and sleeved on the pier; the number of the self-correcting and self-adjusting assemblies is N, and N is an even number greater than or equal to 4, and each two groups of the self-correcting and self-adjusting assemblies are symmetrically arranged 180 degrees with the center of the pier as an axis, and adjacent two groups of the self-correcting and self-adjusting assemblies are arranged at equal intervals along the circular arc length direction of the upper surface of the base;

[0013] The two mounting seats of the two groups of self-correcting and self-adjusting assemblies, which are symmetrically arranged with the center of the pier column as the axis, are linked by a linkage assembly, and the linkage assembly includes: a third connecting seat, a driving rod, a fixed column and a swing arm, two third connecting seats are provided, and the two third connecting seats are respectively fixedly installed on the side walls of the two mounting seats; two driving rods are provided, and one end of each driving rod is rotatably connected to the third connecting seat at the corresponding position; the fixed column is fixedly and vertically installed in the middle of the inner cavity of the base; the swing arm is rotatably sleeved on the fixed column, and the two ends of the swing arm are respectively rotatably connected to the other ends of the two driving rods;

[0014] The two driving rods are centrally symmetrically arranged with the vertical center line of the fixing column as the axis.

[0015] In the above technical solution, the center line of the guide rod is arranged parallel to the radius of the pier column.

[0016] In the above technical solution, a spring is sleeved on the guide rod, and one end of the spring is connected to the side wall of the mounting seat close to the center of the pier column, and the other end of the spring is connected to the side wall of the slider.

[0017] In the above technical solution, a reinforcement seat is installed in the middle of the upper surface of the base, and the reinforcement seat is configured as a hollow annular body, and the bottom end of the pier column is inserted into the inner cavity of the reinforcement seat.

[0018] The above technical solution further includes monitoring components, the number of which is M, and N=2M. The monitoring components are arranged corresponding to the positions of the through slots, and two adjacent groups of the monitoring components are arranged at equal intervals along the length direction of the semicircular arc on the upper surface of the base;

[0019] Each of the monitoring components includes: a vertical seat, a horizontal seat, a first tactile switch, a second tactile switch, a first floating ball, a third tactile switch, a fourth tactile switch, a second floating ball, a connecting pipe, a liquid injection port and a transparent plate. There are two vertical seats, and the two vertical seats are respectively perpendicular to the upper surface of the base; the horizontal seat is arranged at the tops of the two vertical seats and forms a "U"-shaped closed inner cavity with the tops of the two vertical seats; the first tactile switch and the second tactile switch are respectively fixedly installed up and down corresponding to each other in the inner cavity of one of the vertical seats; the first floating ball is arranged between the first tactile switch and the second tactile switch.

[0020] Among them, the first tactile switch and the third tactile switch are on the same horizontal line, and the second tactile switch and the fourth tactile switch are on the same horizontal line.

[0021] In the above technical solution, the distance between the first tactile switch and the second tactile switch is H1, and the diameters of the first floating ball and the second floating ball are H2, and 2H2≥H1≥1.1H2.

[0022] This solution also proposes a deviation correction method, which is realized by the pier auxiliary device for soft foundation described in any one of the above, and includes the following steps:

[0023] Step 1: Preliminary installation of the pier:

[0024] Horizontal positioning of the base member: Horizontally lay the base on the reinforced soft soil foundation, and inject water into the cavities of the vertical seat and the horizontal seat through the liquid injection port to the preset liquid level line, ensuring that the first floating ball and the second floating ball do not trigger the monitoring contacts, and complete the horizontal installation of the base;

[0025] Vertical calibration of the pier: Make the pier pass through the collar from top to bottom, embed its bottom end into the inner cavity of the reinforcement seat, and the bottom end of the pier forms a fixed connection in the inner cavity of the reinforcement seat by pouring. With the help of the horizontal reference of the base and the guidance of the reinforcement seat and the collar, the vertical installation of the pier is realized;

[0026] Step 2: Preliminary self-correction and self-adjustment:

[0027] Tilt sensing and force transmission: When the pier column tilts, the first connecting seat at the collar drives the linkage rod to move the second connecting seat, the mounting seat, and the slider in the corresponding direction. The mounting seat pulls the driving rod at the corresponding position to make the swing arm swing under force.

[0028] Reverse force generation: When the swing arm swings, it drives the drive rod at the corresponding position to generate thrust, which is transmitted through the connecting rod to form reverse pulling force to offset the deflection torque;

[0029] Step 3: Monitoring and early warning of pier column deflection in later stages:

[0030] Over-limit tilt trigger: abnormal soft soil foundation causes the pier column to tilt beyond the automatic adjustment range, causing the base, reinforcement seat and vertical seat to deviate;

[0031] Bidirectional signal acquisition: When the liquid level in the vertical seat cavity forms a height difference, the first float and the second float trigger the second touch switch and the third touch switch respectively;

[0032] Early warning feedback: The second and third touch switches issue early warnings, prompting manual intervention.

[0033] Compared with the prior art, the pier auxiliary device and deviation correction method for soft foundation of the present invention have the following beneficial effects:

[0034] First, the existing soft soil foundation pier correction requires manual intervention to complete excavation and construction operations. There is a lack of autonomous sensing and adaptive adjustment mechanisms when the pier deflects, making it impossible to achieve self-correction in the early stages of deflection. To address the technical bottleneck of existing soft soil foundation pier correction relying on manual intervention and lacking autonomous sensing and adaptive adjustment mechanisms, the present invention, through the coordination of multiple groups of linkage rods, second connecting seats, mounting seats, drive rods and other components arranged symmetrically around the pier axis, can automatically trigger reverse tension to take effect when the pier tends to deflect, thereby ensuring the verticality and stability of the pier. Specifically, the present invention provides a self-correcting and self-adjusting function around the pier. When the pier tends to deflect to one side due to factors such as foundation deformation, the device automatically triggers the reverse tension mechanism on the opposite side through a mechanical transmission mechanism, generating a reverse force that counteracts the deflection force, forcing the pier to achieve force balance in the initial deflection stage and suppressing the development of the tilting trend. This adaptive self-correcting and self-adjusting mechanism does not require manual intervention, can respond to signs of deflection in real time, and maintain the verticality and stability of the pier through dynamic force balance.

[0035] Second, to address the problem of lag in existing manual monitoring, which, if not discovered in time, can easily lead to aggravated deflection and increase the difficulty of subsequent rectification work, the present invention overcomes the time delay limitations of traditional manual monitoring and achieves immediate response to deflection signs through a mechanical adaptive mechanism, reducing the cumulative risk of deflection from the source, significantly simplifying the complexity of subsequent rectification processes, and improving the timeliness and reliability of engineering operations and maintenance, fundamentally solving the lag and passivity problems of traditional manual rectification.

[0036] Third, to address the problem that excessive deflection can easily cause irreversible structural damage, resulting in correction failure and even pier column scrapping, threatening the safety and stability of the project, the present invention uses a real-time self-correction and self-adjustment function to proactively intervene when the pier column shows a slight deflection trend, effectively curbing the continued increase in the deflection angle. This method controls the deflection within a safe threshold, avoiding irreversible structural damage caused by excessive deflection, and eliminating the risk of correction failure and component scrapping caused by excessive deflection. This provides long-term safety protection for the project structure and significantly improves the overall stability and lifespan of the pier column on soft soil foundations.

[0037] Fourth, the present invention constructs a multi-dimensional self-correcting and self-adjusting system, deploying adjustment functions in both the X and Y directions of the pier. Through a symmetrical mechanical balance architecture, it responds in real time to deflection disturbances in different directions, ensuring all-round stability. Furthermore, the system is modularly expandable, allowing for the flexible addition of self-correcting and self-adjusting units based on project requirements. This allows for a closed-loop control module covering the entire circumference of the pier, achieving 360-degree dynamic balance adjustment without blind spots, significantly enhancing the structure's adaptability and overall stability under complex load conditions.

[0038] 5. The present invention integrates multifunctional components such as the horizontal seat, the vertical seat, and the first float to construct a full-cycle verticality monitoring system: During the installation phase, each component uses precision sensing and a visual feedback mechanism to capture the spatial posture information of the pier in real time, intuitively presenting the verticality of the pier installation, providing precise guidance for construction personnel, effectively reducing structural hazards caused by installation deviations, and ensuring high-precision initial installation of the pier; after installation, the monitoring system continues to function, performing real-time dynamic monitoring of the vertical state of the pier. Once a tilt trend is detected, an early warning mechanism is immediately triggered, allowing staff to promptly grasp the structural status; this multifunctional integrated setting breaks the limitations of traditional monitoring equipment with single functions and dispersed layouts, realizing the dual value of the same set of components in the construction and operation and maintenance stages, not only significantly saving equipment installation space and hardware investment costs, but also significantly improving the integration and reliability of the monitoring system, reducing the complexity of later maintenance, and effectively improving engineering construction efficiency and long-term operation and maintenance management by reducing equipment redundancy and optimizing construction and operation and maintenance processes, providing strong protection for the full life cycle safety of piers on soft soil foundations;

[0039] Sixth, the present invention symmetrically deploys two sets of monitoring components within the inner cavities of the two vertical seats. When the horizontal seat and the two sets of vertical seats tilt with the pier and base, the dual-side monitoring components simultaneously collect tilt data and provide visual prompts through a triggering mechanism that activates liquid level fluctuations and a floating ball linkage. Compared to a single-group monitoring mode, this method effectively eliminates the accidental errors and data deviations of single-point monitoring through the parallel collection and cross-verification of dual-channel data, significantly improving the reliability and accuracy of monitoring results.

[0040] 7. In the present invention, the monitoring components on both sides have fault tolerance capabilities. When any monitoring component fails, the other group can still independently complete the monitoring task, continuously output valid data and trigger early warning signals, ensuring the stable operation of the monitoring system throughout its life cycle, completely eliminating monitoring blind spots caused by single point failures, and providing multi-dimensional, highly reliable data support for structural safety assessment;

[0041] 8. The width of the inner cavity of the vertical seat of the present invention forms a matching relationship with the diameter parameters of the first and second floats. This size adaptation scheme not only ensures that the first and second floats can move smoothly in the vertical direction in the two sets of vertical seat cavities, but also ensures that the two can accurately trigger the warning components at corresponding positions during the displacement process by limiting the radial activity space, avoiding lateral offset of the first and second floats when they are raised and lowered due to the excessive width of the vertical seat cavity, thereby effectively solving the trigger failure problem caused by excessive component matching clearance in traditional structures, ensuring that the spatial position correspondence between the warning component and the first and second floats is accurate, and significantly improving the reliability and response accuracy of the monitoring system;

[0042] 9. In the chamber structure formed by the horizontal seat and the vertical seat, the present invention uses a transparent plate made of a transparent material as a sealing component. This transparent sealing arrangement enables real-time visual observation of the position status of the first and second floats in the chamber. In particular, during the initial installation of the pier column, the verticality and installation posture of the pier column can be accurately judged by observing the dynamic changes in the liquid level in the inner cavity of the vertical seat. The use of transparent materials not only meets the chamber sealing performance requirements, but also provides an intuitive visual feedback window for construction personnel, effectively improving the controllability and accuracy of the installation process, avoiding installation deviations caused by blind operation, and laying the foundation for subsequent structural stability.

[0043] 10. The present invention uses a connecting pipe to establish a communication channel between the inner cavities of the two vertical seats. When the pier column and the base tilt as a whole, the principle of a communicating vessel is used to ensure that the liquid in the inner cavities of the two sets of vertical seats can circulate in real time through the connecting pipe, maintaining the liquid levels on both sides at the same horizontal reference line. This arrangement dynamically balances the liquid pressure in the cavities on both sides, eliminating the interference of tilt deformation on the liquid level. It ensures that the first and second floats in the left and right positions are always at the same height, providing a stable and reliable reference surface for verticality monitoring, and effectively improving the accuracy and reference consistency of tilt monitoring data.

[0044] 11. The present invention realizes accurate monitoring of the tilt state through a linkage trigger mechanism: when the pier column and the base tilt as a whole, the first float on the low side synchronously triggers the second touch switch at the low position, and the second float on the high side triggers the third touch switch at the high position; conversely, if the first float triggers the first touch switch at the high position, the second float synchronously triggers the fourth touch switch at the low position; this two-way linkage mode ensures that when the equipment tilts in any direction, the first float and the second float always trigger the warning components at the corresponding heights in a symmetrical manner. Through the synchronous response and cross-verification of the two groups of warning components, the one-sidedness of single-group monitoring is eliminated. Compared with the traditional single-group warning solution, the reliability and anti-interference ability of the monitoring results are significantly improved, providing more comprehensive judgment support for structural safety early warning;

[0045] 12. The present invention provides a reinforcement seat between the pier column and the base. This component provides mechanical support to enhance the verticality of the pier column during installation. Furthermore, the geometric limitation and mechanical conduction mechanism of the constraint interface effectively suppress the tilting deformation of the pier column during use, providing dual protection for the spatial stability of the pier column.

[0046] In summary, the present invention realizes automatic force balancing and suppressing tilting trend in the initial stage of deflection through the circumferential self-correction and self-adjustment system, thus breaking through the lag of manual correction; constructs a multi-dimensional adjustment system to realize full circumferential dynamic balance and improves adaptive ability; integrates multifunctional components to build a full-cycle monitoring system to realize installation assistance and real-time warning, saving space and cost; adopts symmetrical monitoring components to improve data reliability and fault tolerance; precise size adaptation ensures monitoring triggering accuracy; transparent sealing and connecting vessel design ensure observation intuitiveness and benchmark consistency; two-way linkage trigger mechanism eliminates the one-sidedness of single-group monitoring, and comprehensively improves the stability, safety, monitoring accuracy and operation and maintenance efficiency of soft soil foundation piers.

DETAILED DESCRIPTION

[0056] The following is a combination of specific implementation cases and attached Figures 1 to 8 The present invention is further described below, but the present invention is not limited to these embodiments.

[0057] A pier column auxiliary device for soft foundation, used for assisting the deviation correction of the pier column 1, comprising: a base 2, a through slot 3, a collar 4 and a self-correcting and self-adjusting component, the base 2 is vertically arranged at the bottom end of the pier column 1, and the pier column 1 is located at the center of the base 2; a plurality of through slots 3 are provided, in this embodiment, four through slots 3 are provided, and every two through slots 3 form a group symmetrically opened on the base 2; the collar 4 is fixed and sleeved on the pier column 1; the number of self-correcting and self-adjusting components is N, and N is an even number greater than or equal to 4, and every two groups of self-correcting and self-adjusting components are symmetrically arranged 180 degrees with the center of the pier column 1 as the axis, and the two adjacent groups of self-correcting and self-adjusting components are arranged along the upper side of the base 2. The surfaces are arranged at equal intervals in the direction of the circular arc length. In this embodiment, N=4 is taken as an example for explanation, that is, the number of self-correcting and self-adjusting components is set to four, and every two groups of self-adjusting components are symmetrically arranged at 180 degrees with the center point of the pier 1 as the center of the circle, and the two adjacent groups of self-correcting and self-adjusting components are arranged at a distance of 90 degrees along the direction of the circular arc length of the upper surface of the base 2; the present invention constructs a multi-dimensional self-correcting and self-adjusting system, deploys adjustment functions in the XY bidirectional direction of the pier 1, and responds to different directional deflections through a symmetrical architecture; in addition, the number of self-correcting and self-adjusting unit groups can be flexibly increased according to engineering requirements, and a full-circular closed-loop control module can be constructed to improve the structural adaptability and stability.

[0058] The present invention provides a self-correcting and self-adjusting function on the circumference of the pier 1. When the pier 1 has a pre-deflection tendency to one side due to factors such as foundation deformation, the device automatically triggers the opposite side reverse tension mechanism through a mechanical conduction mechanism, thereby forming a reverse force that counteracts the deflection force, forcing the pier 1 to achieve force balance in the initial deflection stage, thereby suppressing the development of the tilting trend. The self-adjusting and self-correcting mechanism does not require human intervention, can respond to signs of deflection in real time, and maintains the verticality and stability of the pier 1 through dynamic force system balance.

[0059] This invention breaks through the traditional manual monitoring model by building a real-time response system based on a mechanical adaptive mechanism, overcoming the time lag bottleneck of traditional monitoring. When signs of structural deflection appear, the system instantly triggers a balancing mechanism through a mechanical transmission link, intervening in regulation at the initial stage of deflection, thereby curbing the accumulation of deflection at its root. This approach significantly reduces the complexity of subsequent correction processes, shortens response time, improves the timeliness and reliability of project operations and maintenance, and completely reverses the lag and passivity of traditional manual correction.

[0060] This invention utilizes a real-time self-correcting and self-adjusting mechanism to proactively intervene when pier 1 exhibits even the slightest tendency to deflect, precisely suppressing the cumulative growth of the deflection angle through dynamic mechanical equilibrium. This approach strictly controls deflection within a safe threshold, effectively avoiding irreversible structural damage caused by excessive deflection and completely eliminating the risk of correction failure and component scrapping due to excessive deflection. This creates a long-term safety barrier for the engineering structure and significantly improves the overall stability and service life of pier 1 in soft soil environments.

[0061] Specific reference Figures 3 to 5 As shown, each set of self-correcting and self-adjusting components includes: a first connecting seat 5, a connecting rod 6 and a second connecting seat 7, the first connecting seat 5 is fixedly installed on the lower surface of the collar 4; one end of the connecting rod 6 is rotatably connected to the first connecting seat 5 through a pin, and the connecting rod 6 slides through the inner cavity of the corresponding position slot 3; the second connecting seat 7 is rotatably connected to the other end of the connecting rod 6 through a pin, and the second connecting seat 7 moves centripetally or centripetally relative to the center of the pier 1; the second connecting seat 7 moves centripetally or centripetally relative to the center of the pier 1 through a guide assembly, and the guide assembly includes: a mounting seat 8, a slider 9, a mounting seat 10 and a guide rod 11, and the mounting seat 8 is fixedly installed at the bottom end of the second connecting seat 7; the slider 9 It is fixedly installed at the bottom end of the mounting seat 8; there are two mounting seats 10, and the two mounting seats 10 are respectively vertically and fixedly installed in the inner cavity of the base 2; the guide rod 11 is fixedly installed between the two mounting seats 10, and the slider 9 is slidably sleeved on the guide rod 11; when the connecting rod 6 is forced to drive the second connecting seat 7 to displace, it can prompt the mounting seat 8 and the slider 9 to move along the outer wall of the guide rod 11, thereby guiding the displacement of the slider 9; specifically, when the pier 1 tends to tilt to the right due to long-term use, the first connecting seat 5 at the bottom right end of the ring 4 will drive the right connecting rod 6 to displace, thereby driving the right second connecting seat 7, the mounting seat 8, and the slider 9 to move to the right synchronously.

[0062] The centerline of the guide rod 11 is arranged parallel to the radius of the pier column 1, thereby ensuring that the displacement of the mounting seat 8 and the second connecting seat 7 driven by the slider 9 is along the radius of the pier column 1, thereby ensuring the stable movement of the linkage rod 6 along the inner cavity of the through groove 3, and achieving the purpose of accurately correcting the reverse support of the collar 4. In addition, a spring 12 is sleeved on the guide rod 11, and one end of the spring 12 is connected to the side wall of the mounting seat 10 near the center of the pier column 1, and the other end of the spring 12 is connected to the side wall of the slider 9. Taking the state where the right side of the collar 4 is subjected to force and is inclined to the right as an example, when the collar 4 drives the linkage rod 6, the second connecting seat 7, the mounting seat 8, and the slider 9 to move away from the center of the pier column 1, it can cause the spring 12 to be forced to stretch, and the elastic force of the spring 12 can initially resist the power of the slider 9 to move outward.

[0063] The two mounting seats 8 of the two groups of self-correcting and self-adjusting components are symmetrically arranged with the center of the pier 1 as the axis, and are linked by a linkage assembly. The linkage assembly includes: a third connecting seat 13, a driving rod 14, a fixed column 15 and a swing arm 16. There are two third connecting seats 13, and the two third connecting seats 13 are respectively fixedly mounted on the side walls of the two mounting seats 8; there are two driving rods 14, one end of each driving rod 14 is rotatably connected to the corresponding third connecting seat 13 through a pin; the fixed column 15 is fixed and vertically mounted in the middle of the inner cavity of the base 2; the swing arm 16 is rotatably sleeved on the fixed column 15 through a bearing, and the two ends of the swing arm 16 are respectively rotatably connected to the other ends of the two driving rods 14 through a pin; wherein the two driving rods 14 are centrally symmetrically arranged with the vertical center line of the fixed column 15 as the axis, thereby ensuring that when one end of the swing arm 16 is driven by one of the driving rods 14 to swing, it can drive the other driving rod 14 to move in the same amplitude in the opposite direction, so as to realize automatic force balancing in the initial stage of deflection of the pier 1 and suppress the tilt trend.

[0064] In addition, in order to ensure further stable installation and connection of the pier 1 on the top of the base 2, a reinforcement seat 17 is installed in the middle of the upper surface of the base 2, and the reinforcement seat 17 is set as a hollow annular body, and the bottom end of the pier 1 is inserted into the inner cavity of the reinforcement seat 17; the present invention adds a reinforcement seat 17 between the pier 1 and the base 2. Through the mechanical support effect of this component, the verticality maintenance ability of the pier 1 during installation is enhanced. At the same time, through the geometric limitation and mechanical conduction mechanism of the constraint interface, the tilt deformation of the pier 1 during use is effectively suppressed, providing double protection for the spatial posture stability of the pier 1.

[0066] Each set of monitoring components includes: a vertical seat 19, a horizontal seat 18, a first tactile switch 20, a second tactile switch 21, a first floating ball 22, a third tactile switch 23, a fourth tactile switch 24, a second floating ball 25, a connecting pipe 26, a liquid injection port 27 and a transparent plate 28. There are two vertical seats 19, and the two vertical seats 19 are respectively perpendicular to the upper surface of the base 2; the horizontal seat 18 is arranged at the tops of the two vertical seats 19, and forms a "U-shaped" closed inner cavity with the tops of the two vertical seats 19; the first tactile switch 20 and the second tactile switch 21 are respectively fixedly installed up and down corresponding to each other in the inner cavity of one of the vertical seats 19; the first floating ball 22 is arranged between the first tactile switch 20 and the second tactile switch 21. The third tactile switch 23 and the fourth tactile switch 24 are respectively fixedly installed up and down corresponding to each other in the inner cavity of the other vertical seat 19; the second floating ball 25 is arranged between the third tactile switch 23 and the fourth tactile switch 24; the connecting pipe 26 is communicatively arranged between the two vertical seats 19, and the position where the connecting pipe 26 is located is lower than the position where the second tactile switch 21 is located; in the present invention, the inner cavities of the two vertical seats 19 are communicated through the connecting pipe 26. By using the principle of communicating vessels, when the pier 1 and the base 2 are tilted as a whole, the liquid in the two chambers can flow in real time, maintaining the same liquid level horizontal reference. By dynamically balancing the liquid pressure, the interference of the tilt on the liquid level flatness is eliminated, ensuring that the first floating ball 22 and the second floating ball 25 are synchronously at the same height, providing a stable reference for the verticality monitoring, and improving the data accuracy and consistency; the liquid injection port 27 is communicatively arranged in the inner cavity of the horizontal seat 18; the transparent plate 28 is hermetically arranged on the front and rear sides of the closed inner cavity formed by the horizontal seat 18 and the vertical seat 19, and the transparent plate 28 is made of a transparent material; in the present invention, in the chamber structure composed of the horizontal seat 18 and the vertical seat 19, the transparent plate 28 made of a transparent material is used as a sealing member to realize the visual monitoring of the first floating ball 22 and the second floating ball 25 in the chamber. During the installation stage of the pier 1, the construction personnel can accurately judge the verticality and installation attitude of the pier 1 by observing the change of the liquid level in the inner cavity of the vertical seat 19, which can take into account both the sealing performance and the visibility, provide intuitive feedback for the installation process, effectively improve the installation accuracy and controllability, and ensure the initial installation quality of the structure; among them, the first tactile switch 20 and the third tactile switch 23 are on the same horizontal line, and the second tactile switch 21 and the fourth tactile switch 24 are on the same horizontal line. Specifically, in the present invention, by optimizing the size matching between the inner cavity of the vertical seat 19 and the first floating ball 22 and the second floating ball 25, not only the smooth vertical movement of the components is ensured, but also their radial displacement is restricted, ensuring accurate triggering of the warning components during lifting, avoiding triggering failure caused by lateral offset, and significantly improving the reliability and response accuracy of the monitoring system.

[0067] The present invention constructs a full-cycle vertical monitoring system by integrating multifunctional components such as the horizontal seat 18, the vertical seat 19, and the first float 22: during the installation phase, precise sensing and visual feedback are used to capture the posture of the pier 1 in real time to ensure high-precision installation; during the operation and maintenance phase, continuous dynamic monitoring is carried out to provide real-time warning of tilt trends; this setting breaks the limitation of the single function of traditional monitoring, realizes the reuse of components in the construction and operation and maintenance phases, saves space and cost, improves system integration and reliability, optimizes full-process management, and provides protection for the safety of the pier 1 throughout its life cycle.

[0068] The present invention symmetrically configures two sets of monitoring components in the inner cavities of the two vertical seats 19. When the pier 1 and the base 2 tilt and drive the horizontal seat 18 and the vertical seat 19 to move, the liquid level fluctuation is used to drive the float to trigger monitoring; the bilateral components synchronously collect data and present it visually, and eliminate single-point monitoring errors through dual-channel data parallel collection and cross-validation, thereby greatly improving the reliability and accuracy of tilt monitoring; the bilateral monitoring components of the present invention have a fault-tolerant design. When a single-side component fails, the opposite-side component can independently assume the monitoring task, continuously output valid data and trigger an early warning, ensuring the stable operation of the monitoring system throughout the entire cycle, completely eliminating the monitoring blind spots caused by single-point failures, and providing multi-dimensional reliable data support for structural safety assessment.

[0069] The present invention realizes precise monitoring of tilt through a linkage trigger mechanism: when the pier 1 and the base 2 tilt, the first float 22 on the low side triggers the second touch switch 21 at the low position, and the second float 25 on the high side triggers the third touch switch 23 at the high position; conversely, if the first float 22 triggers the first touch switch 20 at the high position, the second float 25 triggers the fourth touch switch 24 at the low position. This two-way linkage ensures that when tilted in any direction, the first float 22 and the second float 25 symmetrically trigger the corresponding warning components. Through the synchronous response and cross-verification of the two groups of components, the one-sidedness of single-group monitoring is eliminated, the monitoring reliability and anti-interference ability are significantly improved, and a comprehensive judgment basis is provided for safety early warning.

[0070] Specific main references Figure 7 and Figure 8As shown, the distance between the first touch switch 20 and the second touch switch 21 is H1, the diameter of the first float 22 and the second float 25 is H2, and 2H2≥H1≥1.1H2. A graded response mechanism is constructed within this range: when the pier 1 tilts, when the tilt angle causes the first float 22 and the second float 25 to move without touching the corresponding warning components, the first touch switch 20, the second touch switch 21, the third touch switch 23, and the fourth touch switch 24, it indicates that the current tilt amount is within the structural safety redundancy range and does not affect the overall stability of the pier 1 and the bridge it supports; and when the tilt angle of the pier 1 exceeds the critical threshold, the first float 22 and the second float 25 will accurately trigger the corresponding warning components, and through the mechanical contact signal conversion mechanism, the tilt warning signal will be output immediately, thereby realizing reliable identification of structural abnormality and safety warning.

[0071] It is worth noting that the pier 1 is set to be circular in the present invention, and it can be flexibly set to other shapes such as ellipse, rectangle, etc. according to the use requirements of the pier in the market, and the use requirements can be met by using the collar 4 of the corresponding shape, which will not be repeated or limited here;

[0072] The two sets of corresponding upper and lower swing arms 16 are respectively installed on the fixed column 15 without interfering with each other. Specifically, the upper swing arm 16 is arranged in a "F" shape, and the lower swing arm 16 is arranged in a "I" shape to ensure that when the upper and lower swing arms 16 swing in corresponding directions, there is no interference between the two. Specifically, the two sets of swing arms 16 can swing in the direction of 0-30 degrees without rotating a full circle. The swing arms 16 rotating within this range are fully able to ensure that the connecting rod 6, the second connecting seat 7, and the mounting seat 8 move a sufficient distance.

[0073] The first touch switch 20, the second touch switch 21, the third touch switch 23, and the fourth touch switch 24 are all sensitive touch switches that are commonly used and mature on the market. They can realize the switch function by just touching it lightly without pressing it hard. The electrical life is hundreds of thousands of times. It can meet the above-mentioned usage requirements. The models of the above-mentioned existing components are not described or limited here. In addition, the first touch switch 20, the second touch switch 21, the third touch switch 23, and the fourth touch switch 24 in the present device are all electrically connected to the controller of the existing pier column monitoring site, that is, the present device is used in conjunction with the existing pier column monitoring site. When the first touch switch 20, When the second touch switch 21, the third touch switch 23, and the fourth touch switch 24 are triggered, the signal can be transmitted to the controller of the monitoring site for processing, indicating to the staff that the pier column is tilted and requires timely manual intervention; in addition, in order to further facilitate the first-time determination of the location of the tilted pier column, the first touch switch 20, the second touch switch 21, the third touch switch 23, and the fourth touch switch 24 provided at each pier column are numbered and sequenced in advance, so that after the warning function is triggered, the specific location of the tilted pier column can be known through the controller in the first time. This setting is an existing mature technical means and will not be elaborated or limited here;

[0074] The transparent plate 28 is made of a transparent plate material commonly used on the market. It can be made of a variety of materials, such as transparent acrylic plates, glass plates, polycarbonate plates, etc., as long as it can meet the requirements of sealing the horizontal seat 18 and the vertical seat 19 and being transparent to facilitate observation of the liquid level in the vertical seat 19. It will not be limited or elaborated here.

[0075] The working principle of the pier auxiliary device for soft foundation in this embodiment is as follows:

[0076] During the vertical installation of the pier column 1, the base 2 is first installed horizontally on the soft soil foundation that has been pre-reinforced. The first and second floats 22 and 25 of the two vertical seats 19 are used as horizontal positioning references. During the specific implementation, a fixed amount of liquid is injected into the cavity formed by the vertical seat 19 and the horizontal seat 18 by opening the water injection port 27, so that the liquid level is accurately controlled at the preset liquid level line [i.e., the attached Figure 7 [The height of the liquid level line shown in the figure], in this state, the first float 22 and the second float 25 floating on the liquid surface do not trigger the first touch switch 20, the second touch switch 21, the third touch switch 23, and the fourth touch switch 24 monitoring contacts in the cavity, ensuring that the base 2 is in a horizontal and stable state and completing its installation on the soft foundation; then, the pier column 1 is passed through the collar 4 from top to bottom so that its bottom end is accurately embedded in the inner cavity of the reinforcement seat 17. Through the horizontal reference constraint of the base 2 and the vertical guidance of the reinforcement seat 17 and the collar 4, the pier column 1 is installed vertically with high precision;

[0077] When the pier 1 tends to tilt to the right due to long-term use, the first connecting seat 5 at the right bottom end of the collar 4 will drive the right connecting rod 6 to displace, thereby driving the right second connecting seat 7, the mounting seat 8, and the slider 9 to move to the right synchronously. At this time, the right mounting seat 8 pulls the end of the right driving rod 14 to the right through mechanical transmission, so that the swing arm 16 connected to it is subjected to a counterclockwise swinging torque. During the swinging process of the swing arm 16, the left driving rod 14 is acted upon by the thrust and applies a reverse thrust to the left mounting seat 8 and the second connecting seat 7, which is transmitted through the connecting rod 6 to form a pulling force to the lower left. Finally, under the right deflection trend of the collar 4, a left reverse pulling force is automatically generated, and the deflection torque is offset by the balance of the force system to suppress the development of the tilt. Similarly, when the pier 1 tilts backward, the system automatically generates a forward reverse torque to achieve balance. In addition, by modularly adding self-correcting and self-adjusting units around the pier 1, a full-circumferential closed-loop control network is constructed to achieve 360° dynamic balance adjustment without dead angles, fully covering the deflection disturbance under complex working conditions.

[0078] When a soft soil foundation collapses or other abnormalities cause pier column 1 to tilt to the right after long-term use, and this tilt exceeds the containment range of the self-correcting and self-adjusting unit, the tilt of pier column 1 will cause the base 2, reinforcement seat 17, and corresponding vertical seat 19 to shift synchronously. Taking the right tilt as an example, the deflection of pier column 1 causes the liquid levels in the two front vertical seats 19 to tilt, forming a liquid level difference as shown in Figure 8. During this process, the first float 22 in the left vertical seat 19 descends with the liquid level to trigger the upper surface of the second touch switch 21, while the second float 25 in the right vertical seat 19 rises with the liquid level to trigger the lower surface of the third touch switch 23, generating a bidirectional trigger signal. The triggered second and third touch switches 21 and 23 transmit the tilt signal in real time to the external pier column monitoring system controller via the signal transmission module. After data processing, a precise warning is issued to personnel, indicating that pier column 1 has tilted and deformed beyond the automatic adjustment range.

[0079] The present invention realizes automatic force balancing and suppressing tilting trend in the initial stage of deflection through a circumferential self-correction and self-adjustment system, thus breaking through the lag of manual correction; constructs a multi-dimensional adjustment system to realize full circumferential dynamic balance and improves adaptive capability; integrates multifunctional components to build a full-cycle monitoring system to realize installation assistance and real-time early warning, saving space and cost; adopts symmetrical monitoring components to improve data reliability and fault tolerance; precise size adaptation ensures monitoring triggering accuracy; transparent sealing and connecting vessel design ensure intuitive observation and benchmark consistency; two-way linkage trigger mechanism eliminates the one-sidedness of single-group monitoring, and comprehensively improves the stability, safety, monitoring accuracy and operation and maintenance efficiency of soft soil foundation piers.

[0080] This solution also proposes a correction method, including the following steps:

[0081] Step 1: Preliminary installation of piers:

[0082] Horizontal positioning of foundation components: After pre-treatment of the soft soil foundation, such as deep mixing pile reinforcement and grouting reinforcement, the base 2 is laid horizontally on the foundation surface; the water injection port 27 is opened, and a fixed amount of liquid is slowly injected into the cavity formed by the vertical seat 19 and the horizontal seat 18. The liquid level is monitored in real time until it reaches the preset liquid level line; during this process, it is necessary to ensure that the first float 22 and the second float 25 floating on the liquid surface do not trigger the monitoring contacts of the first touch switch 20, the second touch switch 21, the third touch switch 23, and the fourth touch switch 24 in the cavity, so as to determine that the base 2 is in a horizontal and stable state, and complete the precise horizontal installation of the base 2;

[0083] Pier column vertical calibration: Use lifting equipment to accurately pass pier column 1 from top to bottom through the reserved channel of collar 4, and control the verticality error of the lifting within ±1mm / m; embed the bottom end of pier column 1 into the inner cavity of reinforcement seat 17, pour and fill it with high-strength non-shrinkage grouting material, and use a vibrating and compacting process to form a firm fixed connection between pier column 1 and reinforcement seat 17. With the horizontal reference surface provided by base 2 and the vertical guide structure of reinforcement seat 17 and collar 4, finally achieve high-precision vertical installation of pier column 1, and control the verticality deviation within the allowable range required by the specification;

[0084] Step 2: Initial self-correction and self-adjustment:

[0085] Tilt sensing and force transmission: When the pier 1 tilts due to long-term loads, uneven foundation settlement, or other factors, the first connecting seat 5 at the collar 4 first senses the displacement change caused by the tilt. The first connecting seat 5 drives the linkage rod 6 to produce linear displacement, which in turn drives the second connecting seat 7, mounting seat 8, slider 9 and other transmission components on the right side to move synchronously in the corresponding directions, forming a force transmission chain. The mounting seat 8 pulls the drive rod 14 at the corresponding position, causing the swing arm 16 to withstand the counterclockwise swing torque, completing the secondary amplification and transmission of the tilt force.

[0086] Reverse force generation: The swing arm 16 rotates under the action of the swing torque, and at the same time drives the driving rod 14 at the corresponding position to generate a reverse thrust. This thrust is transmitted and converted by the connecting rod 6 to form a balancing force in the opposite direction of the deflection torque, which can suppress the tilt trend of the pier 1 and achieve preliminary self-balancing adjustment of the structure.

[0087] Step 3: Monitoring and early warning of pier column deflection in later stages:

[0088] Over-limit tilt trigger: When a sudden collapse of the soft soil foundation, a sudden change in the groundwater level, or other abnormal conditions occur, causing the tilt of the pier column 1 to exceed the adjustment capacity of the self-correcting and self-adjusting unit, the tilt of the pier column 1 will cause the base 2, the reinforcement seat 17, and the corresponding vertical seat 19 to shift synchronously through structural conduction. When the tilt angle exceeds the preset safety threshold, the subsequent monitoring and early warning process is triggered;

[0089] Bidirectional signal acquisition: As the pier 1 tilts, a height difference forms between the liquid levels in the two vertical seats 19 on the front side. The principle of communicating vessels is used to achieve dynamic equilibrium and level change transmission between the liquids on both sides. The first float 22 in the left vertical seat 19 descends with the liquid level to trigger the upper surface of the second touch switch 21. The second float 25 in the right vertical seat 19 rises with the liquid level to trigger the lower surface of the third touch switch 23. This generates a bidirectional trigger signal, ensuring accurate perception of the direction and degree of tilt.

[0090] Early warning feedback: The triggered second touch switch 21 and the third touch switch 23 feed back the tilt signal in real time to the external pier monitoring system controller commonly used in the existing market through a wired or wireless signal transmission module. The controller analyzes and processes the received signal, and issues early warning prompts to the operation and maintenance personnel through various means such as sound and light alarms, SMS push, platform pop-up windows, etc. At the same time, it records key data such as the time and angle of the tilt, providing a basis for subsequent manual intervention and maintenance decisions.
