Description

Technical Field

[0001] This invention relates to the field of civil engineering construction and maintenance technology, specifically to a device for adjusting the deviation of end-bearing piles. Background Technology

[0002] End-bearing pile misalignment is a common phenomenon in engineering construction. When the misalignment of the end-bearing pile is significant, it is often scrapped. The common approach is to scrap the problematic pile with the larger misalignment and then add two piles on both sides of the problematic pile. Subsequently, a connecting beam is constructed to connect the two piles to replace the original scrapped pile. The new piles must wait until the concrete reaches the required strength before proceeding to the next stage of construction.

[0003] Because the cost of re-piling is high, the loss of engineering piles due to the misalignment of end-bearing piles is often significant. The construction period for re-piling with a new plan is long and expensive, which has a significant impact on the project construction period. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention aims to provide an end-bearing pile misalignment adjustment device. This device can move end-bearing piles that exceed the allowable deviation specified in the standard to a designated position, avoiding problems such as re-piling; it also reduces the time required to handle problematic piles and improves construction efficiency.

[0005] This invention is achieved through the following technical solution:

[0006] A device for adjusting the misalignment of an end-bearing pile includes:

[0007] A gantry crane is erected along the path from the offset position of the end-bearing pile to the correct position, and a long groove is excavated in the soil around the end-bearing pile along the path. The gantry crane is used to hoist the end-bearing pile along the long groove so that the end-bearing pile moves from the offset position to the correct position.

[0008] A transition connection assembly for connecting the hook and end bearing pile of the gantry frame;

[0009] Protective walls are provided on the side walls of the elongated channel.

[0010] Compared to existing technologies, which suffer from high costs associated with re-piling, significant losses due to pile misalignment leading to the scrapping of engineering piles, and lengthy construction cycles requiring new re-piling plans, this invention provides an end-bearing pile misalignment adjustment device. This device can move end-bearing piles exceeding the allowable deviation specified in the standards to a designated position, avoiding the need for re-piling; it also reduces the time required to handle problematic piles and improves construction efficiency. Specifically, a long, narrow channel is first excavated around the problematic pile, following the path from the misaligned position to the correct position, creating a narrow channel on both sides to allow for displacement. Then, protective walls are erected on the sidewalls of the channel to prevent soil collapse during construction. These protective walls must be parallel to the path direction for subsequent anti-tilting control. Next, a gantry crane is erected, capable of supporting heavy loads, to lift the problematic pile. The gantry crane has a moving module and a hook; its structure is existing technology and will not be described in detail here. When erecting the gantry crane, the gantry crane hook should be positioned in the direction of the path from the off-center position to the correct position. After connecting the gantry crane hook to the problematic pile through the adapter connection assembly, the problematic pile can be moved from the off-center position to the correct position through the gantry crane, thus completing the repositioning of the problematic pile to the correct position.

[0011] Further optimization is needed because the problematic piles are quite long, making them prone to swaying and shaking during lifting, lateral movement, and lowering. Furthermore, to improve construction efficiency, only a narrow distance needs to be maintained between the two sides of the long channel, making it easy for the problematic piles to collide with the side walls, potentially causing damage or even soil disturbance and softening. Therefore, to prevent the problematic piles from colliding with the side walls during movement, an anti-sway component is included. This component comprises two side protection units, located on either side of the end-bearing pile. Each side protection unit includes a long, curved plate and a rolling plate. The long, curved plate is fixed to the side wall of the end-bearing pile and is positioned along its length. The outer surface of the long, curved plate is equipped with a driving element and two vertically distributed sliders. These sliders can slide along the length of the long, curved plate, and the driving element moves the two sliders closer together or further apart.

[0012] The rolling plate has a rolling element on one side, and the upper and lower ends of the other side of the rolling plate are hinged by a connecting rod and a slider, respectively. The rolling plate is located on the center line between the two sliders and away from the long arc-shaped plate. The rolling plate can roll freely on the side wall of the long channel through the rolling element on one side. In this solution, an anti-sway assembly is also provided, which includes two side protection units, each of which includes a long arc-shaped plate. In use, the two long arc-shaped plates can be respectively set to cover both sides of the problem pile and fixed. Two sliders are respectively provided on the outer side wall of the long arc-shaped plate. The two sliders are distributed vertically and can slide up and down under the drive of the driving element. The sliders can be slidably connected to the groove on the long arc-shaped plate by means of dovetail blocks, T-blocks, etc. Two sliders are hinged to a rolling plate via a connecting rod, with the hinge direction being vertical. When the two sliders move away from each other, they can move the rolling plate towards the problematic pile; when they move closer together, they can move the rolling plate towards the retaining wall until it lands on the retaining wall, and then rolls on the retaining wall via rolling elements such as casters. This design, through the limiting effect of the side protection units on both sides, prevents the problematic pile from swaying excessively during lifting, translating, and lowering, avoiding impact damage to the retaining wall and preventing disturbance to the soil.

[0013] To further optimize the design and prevent wall denting caused by single-point contact of the rolling elements, one side of the rolling plate is equipped with several rolling elements, which are omnidirectional balls rotatably connected to the rolling plate. These omnidirectional balls are hinged balls, hinged or rotatably connected to the rolling plate to achieve omnidirectional rotation. The array of omnidirectional balls allows for multi-point contact, reducing damage to the wall.

[0014] To further optimize the process, in order to provide a certain displacement buffer for both sides of the problematic pile during hoisting and avoid hard contact, the side protection unit also includes a limiting plate. The limiting plate is located on the other side of the rolling plate, and the upper and lower ends of the limiting plate are respectively hinged by a connecting rod and a slider.

[0015] Several elastic expansion joints are provided between the limiting plate and the rolling plate to allow for changes in the distance or spacing between them. In this design, a limiting plate is added to the back of the rolling plate, and the rolling plate and the limiting plate are connected by several elastic expansion joints. The slider is hinged to the limiting plate via a connecting rod. Thus, when the rolling plate contacts the retaining wall, and during hoisting, the elastic expansion and contraction of the expansion joints allows for a certain amount of sway buffering on both sides of the problematic pile.

[0016] In a further optimization, to control the distance between the two sides of the problematic pile and the long channel during the lowering of the problematic pile, so as to avoid swaying and tilting during the lowering of the problematic pile, the elastic telescopic component includes a hydraulic rod and a spring. Both ends of the hydraulic rod and the spring are respectively connected to the limiting plate and the rolling plate; the hydraulic rod is located inside the spring.

[0017] A hydraulic cylinder is also provided on the outer side of the elongated arc-shaped plate. This hydraulic cylinder supplies oil to several of the hydraulic rods. In this design, the elastic telescopic component includes a hydraulic rod and a spring. When the problematic pile is lifted and moved horizontally, the hydraulic cylinder does not supply oil to the hydraulic rod, allowing it to extend and retract freely. The spring force provides cushioning. The hydraulic cylinder is mounted on the elongated arc-shaped plate and fixed by a grooved bracket to avoid the screw. When the problematic pile is lowered, the hydraulic cylinder begins supplying oil to the hydraulic rod and controls the hydraulic rod to extend a predetermined length. At this time, the distance between the rolling plate and the limiting plate is fixed, thereby controlling the problematic pile to descend vertically without lateral swaying, ensuring the problematic pile stands vertically in the correct position.

[0018] To further optimize the system and monitor the degree of sway during the displacement of the problematic pile, the side protection unit also includes a displacement sensor. The displacement sensor is fixed to the outside of the long, curved plate, and its detection end passes through the limiting plate and the rolling plate. In this design, a hole is made in the middle of the limiting plate. The displacement sensor is fixed to a hydraulic cylinder, and its detection end passes through the hole and is perpendicularly connected to the rolling plate. The detection end of the displacement sensor can extend and retract freely. Thus, when the problematic pile moves, the displacement amount fed back by the displacement sensor can be used to determine whether it exceeds a threshold. If it exceeds the threshold, it indicates a large sway, at which point the gantry crane is controlled to slow down or even stop until the sway decreases, after which the hoisting is resumed.

[0019] For further optimization, to enable the two sliders to move towards each other or away from each other, the driving component is a rotary motor. The output end of the rotary motor is connected to a double-ended screw. The two threaded sections of the double-ended screw are threadedly connected to the two sliders respectively. The rotation of the double-ended screw is used to drive the two sliders to move closer or further apart. The double-ended screw passes through the two sliders sequentially and has two opposing threaded sections, each threadedly connected to a slider. One end of the double-ended screw is connected to the output end of the rotary motor, while the other end is connected to a bearing housing.

[0020] Further optimization, to limit the forward and backward sway of the problematic pile during the lowering process and thus ensure the verticality of the problematic pile, also includes a lateral limiting component. The lateral limiting component includes a steel pipe and a telescopic motor. An extension plate extends outward from one side of the long arc-shaped plate, and the extension plate has a long hole. The long hole is set along the length direction of the long arc-shaped plate. The steel pipe is placed laterally in the long hole of the two long arc-shaped plates, and the steel pipe can slide along the length direction of the long hole.

[0021] Both ends of the steel pipe have telescopic rods that can extend outwards. Each end of the steel pipe has a telescopic motor on its sidewall. The telescopic motor drives a corresponding telescopic rod to extend outwards and abut against the sidewall of the elongated channel. The end of the telescopic rod furthest from the steel pipe has a magnet. In this design, an extension plate extends outwards from one side of the elongated arc-shaped plate. The steel pipe is placed horizontally at the elongated holes of the two extension plates. When the problematic pile needs to be lowered, once the pile maintains its verticality under its own weight and does not sway, the two telescopic motors are controlled to drive the telescopic rods at both ends to extend outwards until the magnet is attracted to the protective wall (a steel plate). The magnet can be an electromagnet to control its magnetism. Once the magnet is attracted, the entire steel pipe is fixed. The problematic pile is then lowered, preferably with the steel pipe slidingly connected to the elongated hole. Due to the limiting effect of the steel pipe, the problematic pile will not sway back and forth. As the problematic pile gradually moves down, the steel pipe gradually slides upwards at the elongated hole until the problematic pile is lowered to the correct position.

[0022] Further optimization, as a specific structure of a transition connection component, the transition connection component includes a hanging plate, the top surface of which has a lifting ring for hoisting, and the bottom surface of which is circumferentially welded with several U-shaped steel bars;

[0023] Several through holes are made circumferentially along the upper part of the end-bearing pile. A strip steel bar is inserted into each through hole, and both ends of the strip steel bar have protruding sections extending out of the through holes. Each U-shaped steel bar is used to insert a corresponding protruding section. In this design, several through holes can be made on the upper part of the end-bearing pile using a drilling tool. For example, two parallel through holes can be made in one direction, and another two parallel through holes can be made in the opposite direction of the next layer. Then, strip steel bars can be inserted laterally into the through holes. The diameter of the strip steel bar matches the width of the internal groove of the U-shaped steel bar, and the height of the through holes in the upper and lower layers must match the height of the corresponding U-shaped steel bars. During installation, the lifting plate can be placed in a suitable position so that each U-shaped steel bar corresponds to a through hole, and then the strip steel bars can be inserted laterally to complete the transition.

[0024] Further optimization involves fixing a long, curved plate so that it always fits tightly against the outside of the problematic pile. The upper end of the long, curved plate has a top plate that is perpendicular to the long, curved plate and can be placed flat on the top surface of the end-bearing pile. The top plate is connected to the top surface of the end-bearing pile by bolts.

[0025] Within the area of ​​the elongated arc-shaped plate, the corresponding strip-shaped reinforcing bars pass through the elongated arc-shaped plate, and the strip-shaped reinforcing bars passing through the elongated arc-shaped plate are threaded rods. In this scheme, the top plate is perpendicular to the elongated arc-shaped plate. Therefore, during installation, the elongated arc-shaped plate is attached by placing it on the top surface of the problem pile and then pushing it inward. Subsequently, bolts are inserted into the top plate for fixation, and since the strip-shaped reinforcing bars passing through the elongated arc-shaped plate are selected as threaded rods, nuts are screwed into the protruding section of the threaded rods to fix the elongated arc-shaped plate.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] 1. This invention provides an end-bearing pile misalignment adjustment device. Using this solution, end-bearing piles that exceed the allowable deviation specified in the standard can be moved to a designated position, avoiding problems such as re-piling; reducing the time for handling problematic piles and improving construction efficiency.

[0028] 2. The present invention provides an end-bearing pile offset adjustment device. By setting anti-sway components, during the lifting, translation and lowering of the problematic pile, the side protection units on both sides limit the deviation of the problematic pile, which can prevent the problematic pile from swaying and shaking, avoid the wall from being damaged by impact, and avoid disturbing the soil.

[0029] 3. This invention provides an end-bearing pile offset adjustment device. When lowering a problematic pile, the device controls the extension or retraction of the hydraulic rod through the anti-sway component, which can limit the left and right sway of the problematic pile during the lowering process. The device also controls the extension and adsorption of the magnets at both ends of the lateral limiting component, which can limit the front and back sway of the problematic pile during the lowering process, so as to ensure that the problematic pile maintains the predetermined verticality during the lowering process.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0042] Example 1: This Example 1 provides a device for adjusting the offset of an end-bearing pile, such as... Figure 1 As shown, it includes:

[0043] Gantry 2 is erected along the path from the offset position to the correct position of the end bearing pile 1, and a long groove is excavated in the soil around the end bearing pile 1 along the path. The gantry 2 is used to hoist the end bearing pile 1 along the long groove so that the end bearing pile 1 moves from the offset position to the correct position.

[0044] The adapter connection assembly 3 is used to connect the hook of the gantry frame 2 and the end bearing pile 1;

[0045] Protective wall 4: Protective wall 4 is provided on the side wall of the elongated channel.

[0046] Compared to existing technologies, which suffer from high costs associated with re-piling, significant losses due to pile misalignment, and lengthy construction cycles requiring new re-piling plans, this invention provides a pile misalignment adjustment device. This device moves piles exceeding permissible deviations to designated positions, avoiding the need for re-piling, reducing pile handling time, and improving construction efficiency. Specifically, a long trench is excavated around the problematic pile, following the path from the misaligned position to the correct position, creating narrow trenches on both sides to allow for displacement. Protective walls 4 are then erected on the sidewalls of the trenches to prevent soil collapse during construction. These protective walls 4 are parallel to the path direction for subsequent anti-tilting control. A gantry crane 2 is then erected, capable of supporting heavy loads, to lift the problematic pile. The gantry crane 2 has a moving module and a hook, the structure of which is existing technology and will not be described further here. When erecting gantry 2, the movement direction of the hook of gantry 2 should be directed towards the path from the off-center position to the correct position. In this way, after the hook of gantry 2 is connected to the problem pile through the adapter connection assembly, the problem pile can be moved from the off-center position to the correct position through gantry 2, thus completing the repositioning of the problem pile to the correct position.

[0047] Example 2: This Example 2 is a further optimization based on Example 1, providing a specific structure for the anti-sway component 5. For example... Figures 2-6 As shown.

[0048] Because the problematic pile itself is quite long, it is prone to swaying and shaking during lifting, translation, and lowering. Furthermore, to improve construction efficiency, only a narrow distance needs to be set on both sides of the long channel. Therefore, the problematic pile is likely to collide with the protective walls 4 on both sides, potentially causing damage to the protective walls 4 and even disturbing the soil, making it soft. Therefore, to prevent the problematic pile from colliding with the protective walls 4 during movement, an anti-sway component 5 is included. The anti-sway component 5 includes two side protection units, which are respectively located on both sides of the end-bearing pile 1. Each side protection unit includes a long arc-shaped plate 501 and a rolling plate 504. The long arc-shaped plate 501 is fixed to the side wall of the end-bearing pile 1 and is arranged along the length of the end-bearing pile 1. The outer side of the long arc-shaped plate 501 is provided with a driving component 503 and two vertically distributed sliders 502. The sliders 502 can slide along the length of the long arc-shaped plate 501, and the driving component 503 is used to move the two sliders 502 closer together or further apart.

[0049] The rolling plate 504 has a rolling element 506 on one side, and the upper and lower ends of the other side of the rolling plate 504 are hinged by a connecting rod 505 and a slider 502, respectively. The rolling plate 504 is located on the center line between the two sliders 502 and away from the elongated arc plate 501. The rolling plate 504 can roll freely on the side wall of the elongated channel through the rolling element 506 on one side. In this solution, an anti-sway component 5 is also provided. The anti-sway component 5 includes two side protection units, and each side protection unit includes an elongated arc plate 501. In use, the two elongated arc plates 501 can be respectively set to cover both sides of the problem pile and fixed. Two sliders 502 are respectively provided on the outer side wall of the elongated arc plate 501. The two sliders 502 are distributed vertically and can slide up and down under the drive of the driving element 503. The sliders 502 can be slidably connected to the groove on the elongated arc plate 501 by means of dovetail blocks, T-blocks, etc. Two sliders 502 are hinged to a connecting rod 505 and a rolling plate 504 respectively, with the hinge direction being vertical. In this way, when the two sliders 502 move away from each other, they can drive the rolling plate 504 to move towards the problem pile; when the two sliders 502 move closer to each other, they can drive the rolling plate 504 to move towards the retaining wall 4 until the rolling plate 504 lands on the retaining wall 4 and rolls on the retaining wall 4 through rolling elements 506, such as casters. Through the above scheme, during the lifting, translation and lowering of the problem pile, the limiting of the side protection units on both sides can prevent the problem pile from swaying and shaking too much, avoid the retaining wall 4 from being damaged by impact, and avoid disturbing the soil.

[0050] In this embodiment, to avoid single-point contact of the rolling elements causing dents in the protective wall 4, one side of the rolling plate 504 is equipped with several rolling elements 506, which are omnidirectional balls rotatably connected to the rolling plate 504. These omnidirectional balls are hinged balls, hinged or rotatably connected to the rolling plate 504 to achieve omnidirectional rotation; the array of omnidirectional balls allows for multi-point contact, reducing damage to the protective wall 4.

[0051] In this embodiment, during the hoisting process, in order to provide a certain displacement buffer for both sides of the problematic pile and avoid hard contact, the side protection unit also includes a limiting plate 507. The limiting plate 507 is located on the other side of the rolling plate 504, and the upper and lower ends of the limiting plate 507 are respectively hinged by a connecting rod 505 and a slider 502.

[0052] Several elastic expansion joints are provided between the limiting plate 507 and the rolling plate 504 to allow for changes in the distance or spacing between them. In this design, a limiting plate 507 is added to the back of the rolling plate 504, and the rolling plate 504 and the limiting plate 507 are connected by several elastic expansion joints. The slider 502 is hinged to the limiting plate 507 via a connecting rod 505. Thus, when the rolling plate 504 contacts the retaining wall 4, and during hoisting, the elastic expansion and contraction of the expansion joints allows for a certain amount of sway buffering on both sides of the problematic pile.

[0053] In this embodiment, when lowering the problematic pile, in order to control the distance from both sides of the problematic pile to the long channel and avoid the problematic pile from shaking or tilting during lowering, the elastic telescopic component includes a hydraulic rod 508 and a spring 509. Both ends of the hydraulic rod 508 and the spring 509 are respectively connected to the limiting plate 507 and the rolling plate 504; the hydraulic rod 508 is located inside the spring 509.

[0054] A hydraulic cylinder 510 is also provided on the outside of the elongated arc-shaped plate 501. The hydraulic cylinder 510 is used to supply oil to several of the hydraulic rods 508. In this design, the elastic telescopic component includes hydraulic rods 508 and springs 509. When the problematic pile is lifted and moved horizontally, the hydraulic cylinder 510 does not supply oil to the hydraulic rods 508, allowing them to extend and retract freely. The spring force of the spring 509 provides cushioning. The hydraulic cylinder 510 is mounted on the elongated arc-shaped plate 501 and fixed by a slotted bracket to avoid the screw. When the problematic pile is lowered, the hydraulic cylinder 510 begins to supply oil to the hydraulic rods 508 and controls the hydraulic rods 508 to extend to a predetermined length. At this time, the distance between the rolling plate 504 and the limiting plate 507 is fixed, thereby controlling the problematic pile to descend vertically without swaying left or right, ensuring that the problematic pile stands vertically in the correct position.

[0055] In this embodiment, to monitor the degree of sway during the displacement of the problematic pile, the side protection unit also includes a displacement sensor 511. The displacement sensor 511 is fixed to the outside of the long arc-shaped plate 501, and the detection end of the displacement sensor 511 passes through the limiting plate 507 and the rolling plate 504 for connection. In this scheme, a hole is opened in the middle of the limiting plate 507, and the displacement sensor 511 is fixed on the hydraulic cylinder 510. Its detection end passes through the hole and is perpendicularly connected to the rolling plate 504. The detection end of the displacement sensor 511 can extend and retract freely. In this way, when the problematic pile moves, the displacement amount fed back by the displacement sensor 511 can be used to determine whether it exceeds the threshold. If it exceeds the threshold, it means that the sway is large. At this time, the gantry 2 is controlled to decelerate or even stop until the sway is reduced, and then the hoisting is controlled again.

[0056] In this embodiment, to achieve the relative movement or separation of the two sliders 502, the driving component 503 employs a rotary motor. The output end of the rotary motor is connected to a double-ended screw 512. The two threaded sections of the double-ended screw 512 are threadedly connected to the two sliders 502 respectively. The rotation of the double-ended screw 512 drives the two sliders 502 to move closer or further apart. The double-ended screw 512 passes sequentially through the two sliders 502 and has two opposing threads, each threadedly connected to a slider 502. One end of the double-ended screw 512 is connected to the output end of the rotary motor, while the other end is connected to a bearing housing.

[0057] Example 3: Based on Example 2, Example 3 further provides a specific structure for the lateral limiting component 6, such as... Figure 7 As shown.

[0058] To limit the forward and backward sway of the problematic pile during the lowering process and thus ensure its verticality, a lateral limiting component 6 is also included. The lateral limiting component 6 includes a steel pipe 601 and a telescopic motor 602. An extension plate 5011 extends outward from one side of the elongated arc plate 501. The extension plate 5011 has an elongated hole 5012, which is set along the length of the elongated arc plate 501. The steel pipe 601 is placed laterally in the elongated holes 5012 of the two elongated arc plates 501, and the steel pipe 601 can slide along the length of the elongated holes 5012.

[0059] Both ends of the steel pipe 601 are equipped with telescopic rods 603 that can extend outwards. Each end of the steel pipe 601 has a telescopic motor 602 on its sidewall. The telescopic motor 602 drives a corresponding telescopic rod 603 to extend outwards and abut against the sidewall of the elongated channel. The end of the telescopic rod 603 away from the steel pipe 601 has a magnet 604. In this design, an extension plate 5011 extends outwards from one side of the elongated arc-shaped plate 501. The steel pipe 601 is placed at the elongated holes 5012 of the two extension plates 5011 and is placed horizontally. When the problematic pile needs to be lowered, once the pile maintains its verticality and does not sway under its own weight, the two telescopic motors 602 are controlled to drive the telescopic rods 603 at both ends to extend outwards until the magnet 604 is attracted to the protective wall 4. The protective wall 4 is a steel plate, and the magnet 604 can be an electromagnet to control its magnetism. Once the magnet 604 has attracted the pile, the steel pipe 601 is fixed in place. The problem pile is then lowered, preferably with the steel pipe 601 slidingly connected to the elongated hole 5012. Due to the limiting effect of the steel pipe 601, the problem pile will not sway back and forth. As the problem pile gradually moves down, the steel pipe 601 gradually slides upward at the elongated hole 5012 until the problem pile is lowered to the correct position.

[0060] Example 4: Based on Example 2 or 3, Example 4 further provides a specific structure of the adapter connection component 3, such as... Figure 8 As shown.

[0061] The adapter connection assembly 3 includes a lifting plate 301, the top surface of which has a lifting ring 302 for hoisting, and the bottom surface of the lifting plate 301 is welded with a number of U-shaped steel bars 303.

[0062] Several through holes are opened circumferentially along the upper part of the end-bearing pile 1. A strip steel bar 304 is inserted into each through hole. Both ends of the strip steel bar 304 have protruding sections extending out of the through holes, and each U-shaped steel bar 303 is used to insert a corresponding protruding section. In this design, several through holes can be opened on the upper part of the end-bearing pile 1 using a drilling tool. For example, two parallel through holes can be opened in one direction, and another two parallel through holes can be opened in the opposite direction of the next layer. Then, the strip steel bars 304 can be inserted laterally into the through holes. The diameter of the strip steel bar 304 matches the width of the internal groove of the U-shaped steel bar 303, and the height of the through holes opened in the upper and lower layers must match the height of the corresponding U-shaped steel bar 303. During installation, the hanging plate 301 can be placed in an appropriate position so that each U-shaped steel bar 303 corresponds to a through hole, and then the strip steel bar 304 can be inserted laterally to complete the transition.

[0063] In this embodiment, to fix the long arc-shaped plate 501 and ensure that the long arc-shaped plate 501 is always in close contact with the outside of the problem pile, the long arc-shaped plate 501 has a top plate 513 at its upper end. The top plate 513 is perpendicular to the long arc-shaped plate 501 and can be placed flat on the top surface of the end-bearing pile 1. The top plate 513 is connected to the top surface of the end-bearing pile 1 by bolts.

[0064] Within the area of ​​the elongated arc-shaped plate 501, the corresponding strip steel bar 304 passes through the elongated arc-shaped plate 501, and the strip steel bar 304 passing through the elongated arc-shaped plate 501 is a threaded rod. In this scheme, the top plate 513 is perpendicular to the elongated arc-shaped plate 501. Therefore, during installation, the elongated arc-shaped plate 501 can be attached by placing it on the top surface of the problem pile and then pushing it inward. Subsequently, bolts are inserted into the top plate 513 for fixation, and the strip steel bar 304 passing through the elongated arc-shaped plate 501 is selected as a threaded rod. Nuts are screwed into the protruding section of the threaded rod to fix the elongated arc-shaped plate 501.

[0065] How this solution works:

[0066] First, a long strip of trench is excavated around the problematic pile. The trench is excavated along the path from the offset position to the correct position, forming a narrow strip of trench on both sides to allow for displacement space. Then, a retaining wall 4 is erected on the side wall of the long strip of trench to prevent soil collapse during construction. In this process, measurements can be taken in advance, such as measuring the distance and line from the center of the offset position to the center of the correct position, so that the two sides of the retaining wall 4 are parallel to the path direction, which facilitates subsequent anti-tilting control.

[0067] Subsequently, gantry crane 2 is erected. Gantry crane 2 has a moving module and a hook. During the erection of gantry crane 2, the hook of gantry crane 2 is moved in the direction of the path from the deviated position to the correct position. After the erection is completed, the distances from both sides of the problematic pile to the sides of the retaining wall 4 are measured as initial distances. Several through holes are then drilled in the upper part of the problematic pile.

[0068] Then, anti-sway components 5 are installed on both sides of the problem pile. After installation, the hook of the control gantry 2 is lowered to the transfer connection component 3 so that each U-shaped steel bar 303 is aligned with its respective through hole. Then, strip steel bars 304 are inserted laterally into each through hole and U-shaped steel bar 303. The protruding end of the strip steel bar 304 is located in the groove inside the U-shaped steel bar 303 to complete the transfer.

[0069] Subsequently, in the anti-sway assembly 5, the two sliders 502 are controlled to move closer together, causing the rolling plate 504 to abut against the retaining wall 4. At this time, the gantry 2 can be controlled to lift the problematic pile to a certain distance, and after it is in place, it can move in the direction of the correct position.

[0070] When moved to the correct position, the hydraulic cylinder 510 supplies oil and external tools measure to control the extension or retraction of the hydraulic rod 508 between the rolling plate 504 and the limiting plate 507, so that the distance between the two sides of the problem pile and the retaining wall 4 is the same as the initial distance.

[0071] Subsequently, the two telescopic motors 602 in the lateral limiting component 6 are controlled to drive the magnets 604 at both ends to move synchronously in opposite directions until the two magnets 604 are respectively attracted to the protective wall 4 on their respective sides. By extending or retracting the hydraulic rod 508, the left and right sway of the problematic pile during the lowering process can be limited. By extending and attracting the magnets 604 at both ends of the lateral limiting component 6, the front and back sway of the problematic pile during the lowering process can be limited, so as to ensure that the problematic pile maintains the predetermined verticality during the lowering process.

[0072] After the lowering is completed, all components and retaining wall 4 can be removed, grouting reinforcement can be carried out at the bottom of the pile, and finally the entire long channel can be backfilled.
