Description

Technical Field

[0001] This invention relates to a rotation and lifting construction device, and more particularly to an overall rotation and lifting construction device based on intelligent control. This invention also relates to a lifting construction method, and more particularly to an overall rotation and lifting construction method based on intelligent control, belonging to the field of building tilt correction and reinforcement construction technology. Background Technology

[0002] Currently, conventional building tilt correction and lifting construction equipment typically uses multiple independent hydraulic jacking units, which are arranged at different jacking points on the building. A unified electrical control system is used to achieve synchronous lifting control of multiple units, and the overall rotation adjustment is coordinated to achieve the tilt correction operation of the building.

[0003] However, in practical engineering applications, multiple lifting units rely solely on the electrical control system for synchronization, lacking an effective mechanical rigid connection structure. As a result, each lifting unit inevitably generates significant local synchronization errors during the actual lifting process, affecting the building's tilt correction accuracy and effectiveness. In addition, during the jacking and lifting process, the pier cap will tilt and lift synchronously with the building to be corrected, while the steel pipe piles that serve as the supporting foundation will always remain vertically embedded in the foundation. This causes the contact state between the bottom of the jacking jack installed above the pier cap and the top surface of the pier cap to change dynamically. Existing technologies usually use methods such as manually adding shims and temporarily adjusting the installation angle of the jacks to compensate for this. However, such methods are cumbersome to operate, have a strong lag in compensation, and cannot achieve real-time dynamic and accurate compensation of the tilt angle, making it difficult to meet the requirements of high-precision and high-efficiency building tilt correction and lifting construction.

[0004] To address these issues, an intelligent control-based overall rotation and lifting construction device and method were designed. Summary of the Invention

[0005] The main objective of this invention is to provide an overall rotation and lifting construction device and method based on intelligent control, so as to solve the problems in the background art mentioned above.

[0006] The objective of this invention can be achieved by adopting the following technical solution: The intelligent control-based overall rotation and lifting construction device includes at least two sets of lifting units, each set of lifting units including a pile cap and steel pipe piles vertically implanted into the foundation. Anchor rods are pre-embedded at both ends of the top of the pier, and a pile hole for steel pipe piles to pass through is opened in the middle of the pier. A metal pad is fixedly installed on the top of the support platform, and adjacent metal pads are rigidly connected by connecting crossbars to form an overall linkage frame. A U-shaped frame is fixedly installed on the top of the metal pad. An upper crossbeam and a lower crossbeam are vertically slidably installed inside the U-shaped frame. A jack is installed between the upper crossbeam and the lower crossbeam. Both ends of the lower crossbeam are fitted with rectangular sliding sleeves, and the lower crossbeam and the rectangular sliding sleeves are slidably connected in the horizontal direction. The rectangular sliding sleeves are vertically slidably engaged with the inner side wall of the U-shaped frame. The bottom of the lower crossbeam is provided with an adaptive fitting mechanism, and the bottom of the adaptive fitting mechanism is movably fitted with the top of the steel pipe pile. Both ends of the upper crossbeam and the outer wall of the rectangular sliding sleeve are provided with one-way locking mechanisms. The inner wall of the U-shaped frame has multiple sets of vertically equidistant limiting slots corresponding to the positions of the one-way locking mechanisms. The one-way locking mechanisms engage with the limiting slots in a one-way manner to restrict the upward sliding of the upper crossbeam and the rectangular sliding sleeve relative to the U-shaped frame.

[0007] Preferably, the metal pad has a through hole coaxial with the pile hole at its center, and positioning holes for cooperating with the anchor rod are opened at both ends of the metal pad. Both ends of the metal pad are integrally formed with end plates, and slots are opened on the end plates. The two ends of the connecting crossbar are respectively inserted into the slots of two adjacent metal pads and fixedly connected to the end plates by positioning bolts.

[0008] Preferably, the adaptive fitting mechanism includes a ball head, a support rod, and a cover plate. A spherical groove is provided at the bottom center of the lower crossbeam. The ball head is rotatably fitted into the spherical groove. The top end of the support rod is fixedly connected to the bottom of the ball head. The bottom end of the support rod is fixedly connected to the top center of the cover plate. The bottom of the cover plate is tightly engaged with the top end face of the steel pipe pile.

[0009] Preferably, a horizontal groove is provided at the top center of the lower crossbeam along the horizontal direction, a horizontal sliding plate is slidably installed in the horizontal groove, the bottom of the jack is fixedly placed on the top of the horizontal sliding plate, and the top of the jack abuts against the bottom center of the upper crossbeam.

[0010] Preferably, both ends of the lower crossbeam are provided with strip grooves along its length, and the top end of the rectangular sliding sleeve is vertically inserted with a pin, the bottom end of the pin extending into the strip groove to limit the horizontal sliding stroke of the lower crossbeam relative to the rectangular sliding sleeve.

[0011] Preferably, the one-way locking mechanism includes a mounting groove, a trapezoidal insert, and a compression spring. The mounting groove is respectively opened on the two end faces of the upper crossbeam and the outer wall of the rectangular sliding sleeve. The trapezoidal insert is slidably installed in the mounting groove in the horizontal direction. The compression spring is horizontally arranged between the inner wall of the mounting groove and the inner end face of the trapezoidal insert, and is used to push the trapezoidal insert outward and lock it into the corresponding limiting groove.

[0012] Preferably, it also includes an unlocking mechanism, which includes a guide groove and a pull rod. The guide groove is formed on the side wall of the mounting groove and communicates with the outside. One end of the pull rod passes through the guide groove and is fixedly connected to the top of the trapezoidal plug, and is used to pull the trapezoidal plug inward to retract and disengage from the limiting slot.

[0013] Preferably, upper guide wheels are rotatably mounted on the top of both ends of the upper crossbeam, and lower guide wheels are rotatably mounted on the bottom of the outer side wall of the rectangular sliding sleeve. Both the upper and lower guide wheels are in rolling contact with the inner side wall of the U-shaped frame to reduce sliding friction resistance.

[0014] Preferably, the bottom of the U-shaped frame is integrally formed with a base plate, and the base plate has a locking hole for cooperating with the anchor rod. The top of the anchor rod passes through the locking hole and is screwed with a fastening nut. The bottom of the fastening nut is tightly fitted with the top of the base plate.

[0015] This invention also provides a construction method for overall rotation and lifting based on intelligent control, comprising the following steps: Step 1: Construction preparation and foundation construction. Excavate the working pit under the foundation of the building to be tilted, clean the base, drill holes at the predetermined points and insert steel pipe piles to the design depth, pour the foundation and pre-embed anchor rods at both ends of the top of the foundation, and cure to the design strength. Step 2: Assembly and rigid connection of the device. Install metal pads on the top of each support platform in sequence, so that the anchor rods pass through the positioning holes and are temporarily fixed. Insert the two ends of the connecting crossbar into the slots of the adjacent metal pads respectively, and tighten them with positioning bolts to form an overall rigid linkage frame. Step 3: Install and debug the lifting unit. Install a U-shaped frame on the top of the metal pad, pass the anchor rod through the locking hole of the base plate and tighten the fastening nut to fix it. Then, install the lower crossbeam, rectangular sliding sleeve, horizontal sliding plate, jack and upper crossbeam into the U-shaped frame in sequence, and adjust the cover plate of the self-adaptive fitting mechanism to be tightly engaged with the top of the steel pipe pile. Step 4: Intelligent control system calibration. Connect the intelligent electrical control system to each jack, displacement sensor, tilt sensor and pressure sensor, conduct no-load test run, calibrate the zero point of each sensor, and set the lifting speed, synchronization accuracy threshold, tilt correction angle limit and overload protection parameters. Step 5: Step-by-step lifting and intelligent tilt correction. The intelligent electrical control system is activated, and the jacks extend to push the upper crossbeam upwards along the U-shaped frame. The upper crossbeam, through a one-way locking mechanism, drives the U-shaped frame, metal pad, and foundation to lift synchronously. When the jacks reach their maximum stroke limit, the one-way locking mechanism on the rectangular sliding sleeve automatically engages with the corresponding limit slot, limiting the relative position of the lower crossbeam and the U-shaped frame. The jacks retract and reset, and the upper crossbeam automatically moves downwards and locks itself through its own one-way locking mechanism. This process is repeated to achieve continuous step-by-step lifting. During the lifting process, the intelligent electrical control system collects the building's posture data in real time, automatically adjusting the lifting height difference of each lifting unit, and working in conjunction with the overall rigid linkage frame to achieve precise rotation and tilt correction of the building. Simultaneously, the adaptive fitting mechanism, through the universal rotation of the ball head and the lateral sliding of the lower crossbeam, compensates for the tilt angle and horizontal displacement of the foundation in real time, maintaining full-area contact between the cover plate and the top of the steel pipe pile. Step 6: Finishing and permanent reinforcement. Once the verticality and elevation of the building meet the design requirements, lock all one-way locking mechanisms, pour the permanent support structure, and once the permanent support reaches the design strength, operate the unlocking mechanism to release all locks. Remove the construction equipment from top to bottom, backfill the work pit, and complete the construction.

[0016] The beneficial effects of this invention are as follows: The intelligent control-based overall rotation and lifting construction device and method provided by the present invention can forcibly constrain the lifting displacement and rotation angle of multiple lifting units to be consistent by fixing metal pads on the top of each pier and rigidly connecting adjacent metal pads with connecting crossbars. This greatly improves the synchronization accuracy of overall lifting and tilt correction rotation, and avoids the risk of jamming, stress distortion deformation or even breakage caused by asynchronous overall tilt correction. By setting a ball-joint adaptive fitting mechanism consisting of a ball head, support rod, and cover plate at the bottom of the lower crossbeam, and cooperating with the lateral sliding adjustment function of the lower crossbeam inside the rectangular sliding sleeve, the angular deviation and horizontal displacement of the pier cap caused by the building's tilt can be dynamically compensated in real time. During the entire jacking process, the adaptive fitting mechanism can automatically adjust its posture through the free rotation of the ball head and the lateral sliding of the lower crossbeam, ensuring that it always maintains full-area tight contact with the top of the vertical steel pipe pile. This eliminates the problem of uneven distribution of jacking force caused by the reduced contact area in traditional jacking methods. It not only significantly improves the transmission efficiency of jacking force and the accuracy of jacking position, but also avoids the off-center wear of the jack piston rod and seals, extending the service life of the equipment. At the same time, it eliminates the need for frequent manual addition of shims or temporary adjustment of the jack installation angle, greatly improving construction efficiency. By setting a one-way automatic locking mechanism on the side of the upper crossbeam and rectangular sliding sleeve, consisting of an installation groove, a trapezoidal insert, a compression spring, and a limiting slot on the inner side of the U-shaped frame, step-by-step automatic locking can be achieved during the jacking process. After the jack completes a single jacking stroke, the locking mechanism can automatically engage with the corresponding limiting slot, limiting the relative position of the lower crossbeam and the U-shaped frame. During the jack resetting process, the upper crossbeam can automatically move down along the U-shaped frame and complete the next level of locking. There is no need for manual pin insertion or adjustment of the locking position, which realizes continuous and uninterrupted step-by-step lifting operation, simplifies the construction operation process, reduces the intensity of manual labor, and improves the automation level and operational safety of construction.

Detailed Implementation

[0019] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] like Figures 1-9 As shown, this embodiment provides an overall rotation and lifting construction device based on intelligent control, including at least two sets of lifting units, each set of lifting units including a pile cap 1 and a steel pipe pile 2 vertically implanted into the foundation; Anchor rods 102 are pre-embedded at both ends of the top of the pier cap 1, and a pile hole 101 for steel pipe piles 2 to pass through is opened in the middle of the pier cap 1. A metal pad 3 is fixedly installed on the top of the support 1. Adjacent metal pads 3 are rigidly connected by connecting crossbars 4 to form an overall linkage frame. A U-shaped frame 5 is fixedly installed on the top of the metal pad 3. An upper crossbeam 6 and a lower crossbeam 8 are vertically slidably installed inside the U-shaped frame 5. A jack 10 is installed between the upper crossbeam 6 and the lower crossbeam 8. Both ends of the lower crossbeam 8 are fitted with rectangular sliding sleeves 7. The lower crossbeam 8 and the rectangular sliding sleeves 7 are slidably connected in the horizontal direction. The rectangular sliding sleeves 7 are vertically slidably engaged with the inner side wall of the U-shaped frame 5. The bottom of the lower crossbeam 8 is provided with an adaptive fitting mechanism 9. The bottom of the adaptive fitting mechanism 9 is movably fitted with the top of the steel pipe pile 2. One-way locking mechanisms 11 are provided at both ends of the upper crossbeam 6 and on the outer side wall of the rectangular sliding sleeve 7. Multiple sets of vertically equidistant limiting slots 1104 are provided on the inner side wall of the U-shaped frame 5 corresponding to the position of the one-way locking mechanism 11. The one-way locking mechanism 11 and the limiting slots 1104 engage in a one-way engagement to limit the upward sliding of the upper crossbeam 6 and the rectangular sliding sleeve 7 relative to the U-shaped frame 5.

[0021] The device is based on multiple independent lifting units. All metal pads 3 are rigidly connected into an integral linkage frame with no relative displacement through connecting crossbars 4. From the mechanical structure level, the lifting displacement and rotation angle of each lifting unit are completely synchronized. The lower crossbeam 8 is always supported on the top of the fixed steel pipe pile 2 through the adaptive fitting mechanism 9. It only deflects in angle with the tilt of the foundation 1, and its vertical position remains unchanged. During construction, the jack 10 acts as a power output element, driving the U-shaped frame 5, metal pads 3 and foundation 1 to be lifted as a whole through the upper crossbeam 6 and the one-way locking mechanism 11. When the jack 10 reaches the upper limit of a single stroke, the one-way locking mechanism 11 on the rectangular sliding sleeve 7 automatically locks the position of the lower crossbeam 8. After the jack 10 retracts and resets, the upper crossbeam 6 automatically moves down and locks. This process is repeated to achieve continuous step-by-step lifting. During the lifting and tilt correction process, the adaptive fitting mechanism 9, through the omnidirectional rotation of the ball head 901 and the lateral sliding of the lower crossbeam 8, dynamically compensates in real time for the angular deviation and horizontal displacement of the pier cap 1 caused by the building's tilt, maintaining full-area close contact with the vertical steel pipe piles 2 to ensure uniform transmission of the lifting force. The intelligent electrical control system collects real-time data on the building's posture, displacement of each unit, and load, automatically adjusting the output parameters of each jack 10, and working in conjunction with the overall rigid frame to achieve precise rotation and tilt correction of the building.

[0022] In this embodiment, the metal pad 3 has a through hole 301 coaxial with the pile hole 101 at its center, and positioning holes 302 that cooperate with the anchor rod 102 are opened at both ends of the metal pad 3. Both ends of the metal pad 3 are integrally formed with end plates 303, and slots 304 are opened on the end plates 303. The two ends of the connecting crossbar 4 are respectively inserted into the slots 304 of two adjacent metal pads 3 and are fixedly connected to the end plates 303 by positioning bolts 305.

[0023] The metal pad 3 serves as a load-bearing transition component. It is precisely positioned and fixed to the anchor rod 102 pre-embedded in the top of the bearing platform 1 through the positioning hole 302, ensuring that there is no relative displacement between it and the bearing platform 1. Adjacent metal pads 3 are connected to the connecting crossbar 4 through the slot 304 on the end plate 303, and then fastened to form a rigid whole through the positioning bolt 305. This can evenly transmit the lifting force and rotation torque of any lifting unit to all units, forcing all units to maintain a completely synchronized lifting height and rotation angle.

[0024] In this embodiment, the adaptive fitting mechanism 9 includes a ball head 901, a support rod 902, and a cover plate 903. A spherical groove is provided at the bottom center of the lower crossbeam 8. The ball head 901 is rotatably fitted into the spherical groove. The top end of the support rod 902 is fixedly connected to the bottom of the ball head 901. The bottom end of the support rod 902 is fixedly connected to the top center of the cover plate 903. The bottom of the cover plate 903 is tightly engaged with the top end face of the steel pipe pile 2.

[0025] The ball head 901 can rotate freely in all directions within the spherical groove at the bottom of the lower crossbeam 8. It can automatically adjust the posture of the support rod 902 and the cover plate 903 in real time according to the tilt angle of the foundation 1. When the foundation 1 tilts with the building, the ball head 901 rotates to keep the cover plate 903 in a horizontal state and maintain full-area close contact with the top of the vertically embedded steel pipe pile 2. The cover plate 903 is made of a circular steel plate with a diameter larger than that of the steel pipe pile 2, which further increases the contact area, reduces the contact stress, and ensures that the lifting force can be uniformly and stably transmitted to the steel pipe pile 2.

[0026] In this embodiment, a horizontal groove 802 is provided at the top center of the lower crossbeam 8 along the horizontal direction, and a horizontal slide plate 803 is slidably installed in the horizontal groove 802. The bottom of the jack 10 is fixedly placed on the top of the horizontal slide plate 803, and the top of the jack 10 abuts against the bottom center of the upper crossbeam 6.

[0027] When the pier 1 tilts due to the lifting, the lower crossbeam 8 will also tilt. The ball head 901 is always vertically set and rotates inside the lower crossbeam 8, thus applying a certain crossbeam thrust to the lower crossbeam 8 and controlling the lower crossbeam 8 to slide inside the rectangular sliding sleeve 7. Meanwhile, the bottom of the jack 10 slides in the opposite direction relative to the lower crossbeam 8 through the horizontal sliding plate 803, so that the jack 10 always remains vertical to the lower crossbeam 8, avoiding the jack 10 being subjected to horizontal shear force.

[0028] In this embodiment, both ends of the lower crossbeam 8 are provided with strip grooves 801 along its length direction. The top end of the rectangular sliding sleeve 7 is vertically inserted with a pin 701, and the bottom end of the pin 701 extends into the strip groove 801 to limit the horizontal sliding stroke of the lower crossbeam 8 relative to the rectangular sliding sleeve 7.

[0029] The pin 701 and the strip groove 801 cooperate to form a sliding limiting mechanism. The lower crossbeam 8 can slide inside the rectangular sliding sleeve 7 along its length. The sliding stroke is determined by the length of the strip groove 801. When the sliding reaches the limit position, the pin 701 abuts against the end of the strip groove 801 to prevent the lower crossbeam 8 from coming out of the rectangular sliding sleeve 7, thus ensuring the safety and reliability of the structure.

[0030] In this embodiment, the one-way locking mechanism 11 includes a mounting groove 1101, a trapezoidal insert 1102, and a compression spring 1103. The mounting groove 1101 is respectively opened on the two end faces of the upper crossbeam 6 and the outer side wall of the rectangular sliding sleeve 7. The trapezoidal insert 1102 is slidably installed in the mounting groove 1101 in the horizontal direction. The compression spring 1103 is horizontally arranged between the inner wall of the mounting groove 1101 and the inner end face of the trapezoidal insert 1102, and is used to push the trapezoidal insert 1102 outward and lock it into the corresponding limiting slot 1104.

[0031] Employing a ratchet-type one-way locking principle, the trapezoidal insert 1102 has its inclined surface facing downwards and its flat surface facing upwards. When the upper crossbeam 6 or rectangular sliding sleeve 7 slides upwards, the flat surface of the trapezoidal insert 1102 contacts the upper edge of the limiting groove 1104, preventing it from sliding upwards. When the upper crossbeam 6 or rectangular sliding sleeve 7 slides downwards, it is subjected to an inward component force that compresses and squeezes the spring 1103, causing the trapezoidal insert 1102 to retract into the mounting groove 1101, thus allowing it to slide downwards smoothly and achieving a one-way locking function. This mechanism can automatically lock its position after the jack 10 completes a single stroke, eliminating the need for manual locking and enabling continuous step-by-step lifting operations.

[0032] In this embodiment, an unlocking mechanism 12 is also included. The unlocking mechanism 12 includes a guide groove 1201 and a pull rod 1202. The guide groove 1201 is formed on the side wall of the mounting groove 1101 and communicates with the outside. One end of the pull rod 1202 passes through the guide groove 1201 and is fixedly connected to the top of the trapezoidal plug 1102, which is used to pull the trapezoidal plug 1102 to retract inward and disengage from the limiting slot 1104.

[0033] When it is necessary to adjust the position downwards or remove the device, manually pull the lever 1202 and slide it inwards along the guide groove 1201. The lever 1202 drives the trapezoidal insert 1102 to compress the spring 1103 and retract it into the mounting groove 1101, causing the trapezoidal insert 1102 to disengage from the limiting slot 1104. At this time, the upper crossbeam 6 and the rectangular sliding sleeve 7 can slide freely downwards along the U-shaped frame 5. The length of the guide groove 1201 matches the sliding stroke of the trapezoidal insert 1102 to ensure that the locking can be completely released.

[0034] In this embodiment, upper guide wheels 601 are rotatably mounted on the top of both ends of the upper crossbeam 6, and lower guide wheels 702 are rotatably mounted on the bottom of the outer side wall of the rectangular sliding sleeve 7. Both the upper guide wheels 601 and the lower guide wheels 702 are in rolling contact with the inner side wall of the U-shaped frame 5 to reduce sliding friction resistance.

[0035] The upper guide wheel 601 and lower guide wheel 702 convert the sliding friction between the upper crossbeam 6, the rectangular sliding sleeve 7, and the U-shaped frame 5 into rolling friction, significantly reducing frictional resistance during sliding, lowering the power loss of the jack 10, and improving lifting efficiency. Simultaneously, the guide wheel structure acts as a guide, ensuring that the upper crossbeam 6 and the rectangular sliding sleeve 7 slide smoothly along the vertical direction of the U-shaped frame 5, avoiding jamming and skewness, and improving the stability and reliability of the device operation.

[0036] In this embodiment, the bottom of the U-shaped frame 5 is integrally formed with a base plate 501. The base plate 501 has a locking hole 502 that cooperates with the anchor rod 102. The top end of the anchor rod 102 passes through the locking hole 502 and is screwed with a fastening nut. The bottom of the fastening nut is tightly fitted with the top of the base plate 501.

[0037] The U-shaped frame 5 is tightly attached to the metal pad 3 via the base plate 501, and is fixed by tightening the fastening nut after passing through the locking hole 502 through the pre-embedded anchor rod 102 on the top of the support platform 1. This connection method is simple in structure and easy to install, and can evenly transfer the lifting reaction force on the U-shaped frame 5 to the metal pad 3 and the support platform 1, ensuring the connection strength and structural stability. The anchor rod 102 is made of high-strength threaded steel and can withstand huge pull-out force, ensuring that there is no relative displacement between the U-shaped frame 5 and the support platform 1 during the entire lifting process.

[0038] like Figures 1-9 As shown in the figure, this embodiment provides a construction method for overall rotation and lifting based on intelligent control, and the process is as follows: Step 1: Construction preparation and foundation construction. Excavate the working pit under the foundation of the building to be corrected. After cleaning the base, drill holes at the predetermined points and insert steel pipe piles 2 to the design depth. Pour the foundation 1 and pre-embed anchor rods 102 at both ends of the top of the foundation 1. Cure to the design strength. Step 2: Assembly and rigid connection of the device. Install metal pads 3 on the top of each support 1 in sequence, so that the anchor rod 102 passes through the positioning hole 302 and is temporarily fixed. Insert both ends of the connecting crossbar 4 into the slots 304 of the adjacent metal pads 3 respectively, and tighten them with positioning bolts 305 to form an overall rigid linkage frame. Step 3: Install and debug the lifting unit. Install the U-shaped frame 5 on the top of the metal pad 3, so that the anchor rod 102 passes through the locking hole 502 of the base plate 501 and tighten the fastening nut to fix it. Then, install the lower crossbeam 8, rectangular sliding sleeve 7, horizontal sliding plate 803, jack 10 and upper crossbeam 6 into the U-shaped frame 5 in sequence, and adjust the cover plate 903 of the self-adaptive fitting mechanism 9 to be tightly engaged with the top of the steel pipe pile 2. Step 4: Intelligent control system calibration. Connect the intelligent electrical control system to each jack 10, displacement sensor, tilt sensor and pressure sensor, conduct no-load test run, calibrate the zero point of each sensor, and set the lifting speed, synchronization accuracy threshold, tilt correction angle limit and overload protection parameters. Step 5: Step-by-step lifting and intelligent tilt correction. The intelligent electronic control system is activated. Jack 10 extends and pushes the upper crossbeam 6 to slide upwards along the U-shaped frame 5. The upper crossbeam 6, through the one-way locking mechanism 11, drives the U-shaped frame 5, metal pad 3, and support platform 1 to lift synchronously. When jack 10 reaches its maximum single stroke limit, the one-way locking mechanism 11 on the rectangular sliding sleeve 7 automatically engages with the corresponding limit slot 1104 to limit the relative position of the lower crossbeam 8 and the U-shaped frame 5. Jack 10 retracts and resets, and the upper crossbeam 6 automatically moves downwards and passes through... The self-locking mechanism 11 locks and repeats the above process to achieve continuous step-by-step lifting; during the lifting process, the intelligent electric control system collects the building posture data in real time, automatically adjusts the lifting height difference of each lifting unit, and cooperates with the overall rigid linkage frame to achieve precise rotation and tilt correction of the building; at the same time, the adaptive fitting mechanism 9 compensates for the tilt angle and horizontal displacement of the pier 1 in real time through the universal rotation of the ball head 901 and the lateral sliding of the lower crossbeam 8, and maintains full-area contact between the cover plate 903 and the top of the steel pipe pile 2. Step 6: Finishing and permanent reinforcement. After the verticality and elevation of the building meet the design requirements, lock all one-way locking mechanisms 11, pour the permanent support structure, and after the permanent support reaches the design strength, operate the unlocking mechanism 12 to release all locks, dismantle the construction devices from top to bottom, backfill the work pit, and complete the construction.

[0039] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
