Description

Technical Field

[0001] This invention belongs to the field of pipe pile verticality monitoring technology, and more specifically, relates to an integrated construction device and construction method for real-time monitoring and adjustment of pipe pile verticality. Background Technology

[0002] As a crucial part of the construction industry, traditional pipe pile construction often suffers from excessive deviations in verticality due to vibration. Monitoring verticality using two theodolites or total stations at a 90-degree angle is not only time-consuming and labor-intensive, but also lacks real-time data and timely correction. Therefore, a construction method for real-time monitoring and control of verticality deviation is urgently needed to solve these problems, ensure construction quality, and improve construction efficiency.

[0003] To address the technical problem of adjusting the verticality deviation of pipe piles, Chinese invention patent CN114777740A discloses a pipe pile verticality detection device and method, including a pile body circumference measuring positioning component and a verticality detector. The pile body circumference measuring positioning component is a strip-shaped structure with a sliding groove along its length. The component is wound around the pipe pile radially to form a positioning ring. The verticality detector includes a mounting base that fits into the sliding groove. The detector slides on the positioning ring via the mounting base, enabling the detection of verticality at different positions of the pipe pile. When the pile body circumference measuring positioning component is wound around the outer wall of the pipe pile, ensuring a proper fit, the verticality detector mounted on it is naturally parallel to the central axis of the pipe pile, resulting in more accurate and reliable verticality measurements. Therefore, the pipe pile verticality detection device provided in this application is easy to operate, has high detection accuracy, and high efficiency. Furthermore, Chinese utility model patent CN214738066U discloses a guide device for adjusting the verticality of steel pipe piles, including an upper verticality guide steel pipe, the original section of the steel pipe pile, a jack, a verticality positioning platform, and a stiffening plate. The upper verticality guide steel pipe and the original section of the steel pipe pile are connected by the stiffening plate. The verticality positioning platform is equipped with the upper verticality guide steel pipe and the jack. The jack is used to adjust the verticality of the upper verticality guide steel pipe. This utility model uses an upper verticality guide steel pipe and a verticality positioning platform for verticality adjustment. The stiffening plate has high rigidity, and the welded joints are not easily deformed, resulting in good verticality adjustment effect, high verticality adjustment accuracy, and convenient construction. It allows concrete slurry to overflow from the reserved gap, reducing concrete waste and eliminating the need for concrete demolition, thus reducing construction time and saving construction costs. It has a simple structure, low cost, is easy to disassemble, can be reused, and is economical and environmentally friendly.

[0004] Among the above technical problems, the following issues still exist: (1) Patent technology CN114777740A installs the verticality detection device on the outer wall of the pipe pile, which obviously makes it easy to cause interference during the process of lowering the pipe pile into the hole, thus causing damage to the device or the pipe pile; (2) During on-site construction, the verticality detection and adjustment process of the pipe pile is usually handled separately, and the control and adjustment process is completed manually after analyzing the detection data. The automation of this scheme needs to be improved; (3) The adjustment device proposed by patent technology CN214738066U is to install multiple jacks in a horizontal posture to provide the pipe pile with a horizontal thrust. Although this scheme can achieve the deviation adjustment of the pipe pile, due to the principle of force interaction, a reaction force of the same magnitude as the filling thrust is generated at the tail of the jack, which causes the device frame structure to generate large stress. After a long period of use, it is inevitable that the fatigue strength will decrease rapidly. In addition, the number of jacks used in this scheme is also relatively large. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an integrated construction device for real-time monitoring and adjustment of pipe pile verticality. By employing a claw mechanism to place the verticality detection device inside the pipe pile, and setting the linear drive component of the adjustment device to an oblique support mode, and utilizing the gravity of the plumb bob to design an electrode contact type offset adjustment unit, this invention not only eliminates the technical problem of interference between the pipe pile and the detection device during the lowering process in existing technologies, but also reduces the stress on the frame structure of the adjustment device and the amount of linear drive components required through oblique support. Simultaneously, the electrode contact type detection device design is simple, effective, and cost-effective. Through the integrated structural design of the detection and adjustment devices, an information closed loop is achieved, saving manpower and significantly improving construction efficiency and quality.

[0006] According to a first aspect of the present invention, a construction device for real-time monitoring and adjustment of the verticality of pipe piles includes:

[0007] A pipe pile adjustment unit fixedly installed on the ground for lowering and adjusting the verticality of the pipe pile; a deviation feedback unit for detecting the deviation status during the lowering process of the pipe pile; and an inner wall clamping positioning unit for coaxially positioning and clamping the deviation feedback unit to the inner wall of the pipe pile.

[0008] The pipe pile adjustment unit includes a horizontal positioning plate fixed on the ground, a central through hole opened in the center of the horizontal positioning plate, at least three first rotating connecting shafts equidistantly distributed on the upper surface of the horizontal positioning plate with the central through hole as the center, a support arm rotatably connected to the first rotating connecting shafts, a linear drive part located in the middle of the support arm, and a sliding limiting assembly rotatably connected to the upper end of the support arm through a second rotating connecting shaft.

[0009] The inner wall snap-fit ​​positioning unit includes a central cylinder for mounting the offset feedback unit, a first support ring, a second support ring, a third support ring, and a fourth support ring sequentially sleeved on the outer wall of the central cylinder from bottom to top, a wall-supporting assembly disposed between the first and second support rings and between the third and fourth support rings, a transmission sleeve sleeved on the outer wall of the central cylinder and disposed between the second and third support rings, a retracting claw spring sleeved on the outer wall of the central cylinder and disposed between the first and second support rings and between the third and fourth support rings, and a pressing assembly for controlling the axial linear movement of the fourth support ring; the first support ring is fixedly connected to the transmission sleeve, and the second, third, and fourth support rings are slidably connected to the transmission sleeve;

[0010] The wall support assembly includes a first connecting rod arm and a second connecting rod arm that are rotatably connected to the support ring via a first hinge shaft and a second hinge shaft, respectively. The first connecting rod arm and the second connecting rod arm are rotatably connected, and a top block that contacts the inner wall of the pipe pile is provided at the rotatable connection point between the first connecting rod arm and the second connecting rod arm.

[0011] The processor connects the offset feedback unit, the pipe pile adjustment unit, and the inner wall snap-fit ​​positioning unit.

[0012] Preferably, the offset feedback unit includes:

[0013] The system includes a detection chamber located at the center of the central cylinder, an end cap located at the top of the central cylinder, a hammer suspended below the end cap by a steel wire core, a motion buffer assembly located on the inner wall of the detection chamber at the same horizontal height as the center of the hammer to buffer the up-and-down movement of the hammer, a first electrode plate located on the inner wall of the detection chamber at different positions at the same horizontal height as the bottom of the hammer, and a second electrode plate located on the side of the bottom of the hammer.

[0014] Preferably, the contact surface of the top block is toothed and made of rubber.

[0015] Preferably, the linear drive unit is a linear motor, a cylinder, a hydraulic cylinder, or a gear and rack mechanism.

[0016] Preferably, the sliding limiting component includes:

[0017] The limiting cylinder section is fixedly connected to the second rotating connecting shaft; the positioning flange located at the edge of the limiting cylinder section for connecting adjacent limiting cylinder sections to each other; the positioning bolt group for positioning adjacent positioning flanges; and the pulley group located on the inner wall surface of the limiting cylinder section.

[0018] Preferably, the motion cushioning component includes:

[0019] Multiple closed-loop conductors fixed to the inner wall of the detection chamber;

[0020] The hammer is made of a strong magnetic material.

[0021] Preferably, the pressing component includes:

[0022] A threaded tooth located at the top of the central cylinder, and a pressure nut threadedly connected to the threaded tooth.

[0023] Preferably, the pressing component includes:

[0024] A threaded sleeve is rotated and fitted on the top of the central cylinder, and a threaded tooth is provided inside the fourth support ring. The threaded sleeve and the threaded tooth cooperate and drive each other.

[0025] Preferably, the inner wall snap-fit ​​positioning unit includes:

[0026] A laser emitter is positioned at the bottom of the central cylinder along its central axis.

[0027] According to a second aspect of the present invention, a construction method for an integrated construction device for real-time monitoring and adjustment of pipe pile verticality is characterized by comprising the following steps:

[0028] S100: The staff positions the horizontal positioning plate to the ground, ensuring that the central through hole and the borehole remain connected, and at the same time installs the other components of the pipe pile adjustment unit;

[0029] S200: Place the offset feedback unit and the inner wall snap-in positioning unit into the inner wall of the pipe pile;

[0030] S300: Activate the pressing component in the inner wall snap-fit ​​positioning unit to control the fourth support ring to move downward along the central axis of the central cylinder and approach the third support ring. Under the lateral support of the first and second connecting rod arms, the top block extends outward and abuts against the inner wall of the pipe pile. Since the first support ring is fixedly connected to the central cylinder, the third support ring presses down the second support ring through the transmission sleeve, causing it to approach the first support ring. This causes the top blocks at the top and bottom to extend outward simultaneously and abut against the inner wall of the pipe pile.

[0031] S400: Install the plumb bob in the detection chamber and power on the device. The second electrode in the offset feedback unit is energized. When the first electrode and the second electrode at different positions on the inner wall of the pipe pile come into contact, a closed circuit can be formed.

[0032] S500: The pipe wall is placed in the sliding limit assembly by a crane and lowered into the drill hole inside the central through hole;

[0033] S600: The pipe pile is extended and pressed into the borehole by hammering. If the pipe pile deviates during the pressing process, the hammer will remain vertical under the action of gravity and make the second electrode plate contact the first electrode plate in the tilt direction, thereby transmitting the tilt and deviation signal to the processor to realize the deviation detection.

[0034] S700: The processor controls the linear drive unit in the pipe pile adjustment unit to perform telescopic movement, thereby controlling the sliding limit component to tilt in the opposite direction to counteract the pipe pile's tilt and achieve offset adjustment.

[0035] S800: After the pipe pile is fully lowered into the borehole, the movement of the fourth support ring is controlled in reverse by the pressing component. Under the action of the retracting claw spring, the top block of the inner wall locking positioning unit releases the tight contact pressure with the pipe pile. Then, the equipment is disassembled to complete the integrated construction process of pipe pile deviation detection and adjustment.

[0036] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0037] 1. This invention discloses an integrated construction device for real-time monitoring and adjustment of pipe pile verticality. It employs a claw mechanism to place the verticality detection device inside the pipe pile, and sets the linear drive component of the adjustment device in an oblique support mode. Furthermore, it utilizes the gravity of the plumb bob to design an electrode contact type offset adjustment unit. This invention not only eliminates the technical problem of interference between the pipe pile and the detection device during the lowering process in existing technologies, but also reduces the stress on the frame structure of the adjustment device and the amount of linear drive components required through oblique support. Simultaneously, the electrode contact type detection device has a simple and effective design with relatively low cost. The integrated design of the detection and adjustment devices achieves a closed-loop information system, saves manpower, and greatly improves construction efficiency and quality.

[0038] 2. The present invention provides an integrated construction device for real-time monitoring and adjustment of pipe pile verticality. By adopting the "rejection upon arrival and retention upon departure" principle of Lenz's law, it solves the technical problem that during the process of pressing pipe piles using the hammering method, the hammer is prone to vertical displacement pulses due to inertia and impact force, which causes abnormal triggering of the electrode plates. During construction, when the pipe pile is hammered, the hammer's velocity is zero at the moment of hammering, while the pipe pile's velocity is downward, thus generating a relative motion tendency between the hammer and the pipe pile. Subsequently, relative displacement occurs. At this time, due to the relative motion of the strongly magnetic hammer between the closed loop conductors, an induced electromotive force is generated inside the closed loop conductors, which in turn generates a force on the magnetic hammer in the opposite direction of motion, hindering its movement and achieving the technical effect of slow descent, thereby improving the stability of the hammer's posture.

[0039] 3. The present invention provides an integrated construction device for real-time monitoring and adjustment of pipe pile verticality. By setting up a laser emitter, it solves the technical problem that it is difficult to determine whether the inner wall clamping and positioning unit is properly clamped when it is clamped to the inner wall of the pipe pile. During construction, the laser emitter is turned on and the direction of the laser is observed at the other end of the pipe pile. At the same time, the pressing component is controlled to perform inner wall clamping. When the laser points to the center of the pipe pile, it indicates that the inner wall clamping and positioning unit is in the center position of the pipe pile. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0051] like Figures 1-5 As shown in the embodiment of the present invention, the integrated construction device for real-time monitoring and adjustment of pipe pile verticality includes:

[0052] The pipe pile adjustment unit 1 is fixedly installed on the ground for lowering and adjusting the verticality of the pipe pile 2; the deviation feedback unit 4 is used to detect the deviation status during the lowering process of the pipe pile; and the inner wall clamping positioning unit 3 is used to coaxially position and clamp the deviation feedback unit 4 to the inner wall of the pipe pile 2.

[0053] The pipe pile adjustment unit 1 includes a horizontal positioning plate 101 fixed on the ground, a central through hole 102 opened at the center of the horizontal positioning plate 101, at least three first rotating connecting shafts 111 equidistantly distributed around the central through hole 102 on the upper surface of the horizontal positioning plate 101, a support arm 112 rotatably connected to the first rotating connecting shafts 111, a linear drive part 113 located in the middle of the support arm 112, and a sliding limiting assembly 120 rotatably connected to the upper end of the support arm 112 through a second rotating connecting shaft 114.

[0054] The inner wall snap-fit ​​positioning unit 3 includes a central cylinder 300 for mounting the offset feedback unit 4, a first support ring 301, a second support ring 302, a third support ring 303, and a fourth support ring 304 sequentially sleeved on the outer wall of the central cylinder 300 from bottom to top, a wall support assembly disposed between the first support ring 301 and the second support ring 302 and between the third support ring 303 and the fourth support ring 304, and a wall support assembly sleeved on the outer wall of the central cylinder 300 and disposed between the second support ring 302 and the third support ring 304. The transmission sleeve 311 between 303, the claw spring 312 sleeved on the outer wall of the central cylinder 300 and disposed between the first support ring 301 and the second support ring 302 and the third support ring 303 and the fourth support ring 304, and the pressing assembly 313 for controlling the linear movement of the fourth support ring 304 along the axial direction; the first support ring 301 is fixedly connected to the transmission sleeve 311, and the second support ring 302, the third support ring 303 and the fourth support ring 304 are slidably connected to the transmission sleeve 311;

[0055] The wall support assembly includes a first connecting rod arm 306 and a second connecting rod arm 308 that are rotatably connected to the support ring via a first hinge shaft 305 and a second hinge shaft 309, respectively. The first connecting rod arm 306 and the second connecting rod arm 308 are rotatably connected, and a top block 307 that contacts the inner wall of the pipe pile 2 is provided at the rotatable connection point between the first connecting rod arm 306 and the second connecting rod arm 308.

[0056] The processor connects the offset feedback unit 4, the pipe pile adjustment unit 1, and the inner wall snap-fit ​​positioning unit 3.

[0057] like Figures 2-4 As shown, in this embodiment of the invention, the offset feedback unit 4 includes a detection chamber 400 located at the center of the central cylinder 300, an end cap located at the top of the central cylinder 300, a hammer 412 suspended below the end cap by a steel wire core 414, a motion buffer assembly 401 located on the inner wall of the detection chamber 400 at the same horizontal height as the center of the hammer 412 for buffering the up-and-down movement of the hammer 412, a first electrode plate 411 located on the inner wall of the detection chamber 400 at different positions at the same horizontal height as the bottom of the hammer 412, and a second electrode plate 413 located on the bottom side of the hammer 412.

[0058] In this embodiment of the invention, the contact surface of the top block 307 is toothed and made of rubber.

[0059] The working principle of this invention embodiment is as follows: First, the worker positions the horizontal positioning plate 101 to the ground, ensuring that the central through hole 102 is connected to the borehole, and simultaneously installs the other components of the pipe pile adjustment unit 1; then, the offset feedback unit 4 and the inner wall snap-fit ​​positioning unit 3 are placed into the inner wall of the pipe pile 2; next, the pressing component 313 in the inner wall snap-fit ​​positioning unit 3 is activated, controlling the fourth support ring 304 to move downward along the central axis of the central cylinder 300 and approach the third support ring 303, thereby aligning the first connecting rod arm 306 with the second connecting rod arm 303. Under the lateral support of 08, the top block 307 extends outward and abuts against the inner wall of the pipe pile 2. Since the first support ring 301 is fixedly connected to the central cylinder 300, the third support ring 303 presses down the second support ring 302 through the transmission sleeve 311, causing it to approach the first support ring 301. This causes the top blocks 307 at both the top and bottom to extend outward simultaneously and abut against the inner wall of the pipe pile 2. Next, the plumb bob 412 is installed in the detection chamber 400, and the device is powered on. The second electrode plate 413 in the offset feedback unit 4 is energized, and the offset feedback unit 4 energizes the second electrode plate 413 at different positions on the inner wall of the pipe pile 2. When the first electrode plate 411 and the second electrode plate 413 come into contact, they form a closed circuit. Next, the pipe pile 2 is placed in the sliding limiting assembly 120 by a crane and lowered into the borehole inside the central through hole 102. Then, the pipe pile 2 is pushed into the borehole using a hammering method. During this pressing process, if the pipe pile 2 becomes tilted, the hammer 412 will remain vertical under gravity, causing the second electrode plate 413 to come into contact with the first electrode plate 411 in the tilted direction, thereby transmitting a tilt / deviation signal to the processor to achieve deviation detection. The processor then controls the linear drive unit 113 in the pile adjustment unit 1 to extend and retract, thereby controlling the sliding limit component 120 to tilt in the opposite direction to counteract the tilt of the pile 2 and achieve offset adjustment. Next, after the pile 2 is completely lowered into the borehole, the pressing component 313 controls the movement of the fourth support ring 304 in the opposite direction. Under the action of the retracting claw spring 312, the top block 307 of the inner wall locking positioning unit 3 releases the tight contact pressure with the pile 2. Then, the equipment is disassembled to complete the integrated construction process of offset detection and adjustment of the pile 2.

[0060] In this embodiment of the invention, a verticality detection device is placed inside the pipe pile 2 using a claw mechanism, and the linear drive component of the adjustment device is set to an oblique support mode. Furthermore, an electrode contact type offset adjustment unit is designed using the gravity of the plumb bob. This invention not only eliminates the technical problem of interference between the pipe pile 2 and the detection device during the lowering process in the prior art, but also reduces the stress on the frame structure of the adjustment device and the amount of linear drive device used by the oblique support. At the same time, the electrode contact type detection device has a simple and effective design and is relatively inexpensive. Through the integrated structural design of the detection device and the adjustment device, an information closed loop is achieved, saving human resources and greatly improving construction efficiency and quality.

[0061] like Figure 1 As shown, in this embodiment of the invention, the linear drive unit 113 is a linear motor, a cylinder, a hydraulic cylinder, or a gear and rack mechanism.

[0062] like Figure 1 and Figure 5 As shown, in this embodiment of the invention, the sliding limiting component 120 includes:

[0063] The limiting cylinder section 121 is fixedly connected to the second rotating connecting shaft 114; the positioning flange 122 is provided at the edge of the limiting cylinder section 121 for connecting adjacent limiting cylinder sections 121 to each other; the positioning bolt group 123 is used to position adjacent positioning flanges 122; and the pulley group 124 is provided on the inner wall surface of the limiting cylinder section 121.

[0064] like Figure 3 and Figure 4 As shown, in this embodiment of the invention, the motion buffer component 401 includes:

[0065] Multiple closed-loop conductors fixed to the inner wall of the detection chamber 400;

[0066] The hammer 412 is made of a strong magnetic material.

[0067] In this embodiment of the invention, by employing the "rejection upon arrival, retention upon departure" principle of Lenz's law, the technical problem of vertical displacement pulses easily occurring in the hammer 412 during the process of pressing down the pipe pile 2 using the hammering method is solved, which causes abnormal triggering of the electrode plates due to the action of inertia and impact force. During construction, when the pipe pile 2 is hammered, the speed of the hammer 412 is zero at the moment of hammering, while the speed of the pipe pile is downward, thus generating a relative motion tendency between the hammer 412 and the pipe pile 2. Immediately afterwards, relative displacement occurs. At this time, due to the relative motion of the strongly magnetic hammer 412 between the closed loop conductors, an induced electromotive force is generated inside the closed loop conductors, which in turn generates a force on the magnetic hammer 412 in the opposite direction of motion, hindering its movement and achieving the technical effect of slow descent, thereby improving the stability of the hammer's posture.

[0068] like Figure 2 As shown, in this embodiment of the invention, the pressing component 313 includes:

[0069] A threaded tooth is located at the top of the central cylinder 300, and a pressure nut is threaded to the threaded tooth.

[0070] like Figure 2 As shown, in this embodiment of the invention, the pressing component 313 includes:

[0071] A threaded sleeve is rotated on the top of the central cylinder 300, and a threaded tooth is provided inside the fourth support ring 304. The threaded sleeve and the threaded tooth cooperate and drive each other.

[0072] like Figure 3 As shown, in this embodiment of the invention, the inner wall snap-fit ​​positioning unit 3 includes:

[0073] A laser emitter 421 is installed at the bottom of the central cylinder 300 along the central axis of the central cylinder 300.

[0074] In this embodiment of the invention, by setting a laser emitter 421, the technical problem of whether the inner wall snap-fit ​​positioning unit 3 is snapped into place when it is snapped into the inner wall of the pipe pile 2 is solved. During the construction process, the laser emitter 421 is turned on and the direction of the laser is observed at the other end of the pipe pile 2. At the same time, the pressing component 313 is controlled to snap into the inner wall. When the laser is pointed to the center of the pipe pile 2, it can be indicated that the inner wall snap-fit ​​positioning unit 3 is in the center position of the pipe pile 2.

[0075] A construction method for an integrated construction device for real-time monitoring and adjustment of pipe pile verticality includes the following steps:

[0076] S100: The staff positions the horizontal positioning plate 101 to the ground, ensuring that the central through hole 102 is connected to the borehole, and at the same time installs the other components of the pipe pile adjustment unit 1.

[0077] S200: Place the offset feedback unit 4 and the inner wall snap-in positioning unit 3 into the inner wall of the pipe pile 2;

[0078] S300: Activate the pressing component 313 in the inner wall snap-fit ​​positioning unit 3 to control the fourth support ring 304 to move downward along the central axis of the central cylinder 300 and approach the third support ring 303. Thus, under the lateral support of the first connecting rod arm 306 and the second connecting rod arm 308, the top block 307 extends outward and abuts against the inner wall of the pipe pile 2. Since the first support ring 301 is fixedly connected to the central cylinder 300, the third support ring 303 presses down the second support ring 302 through the transmission sleeve 311 to make it close to the first support ring 301, so that the top blocks 307 at the top and bottom extend outward at the same time and abut against the inner wall of the pipe pile 2.

[0079] S400: Install the plumb bob 412 in the detection chamber 400 and power on the device. The second electrode plate 413 in the offset feedback unit 4 is energized. When the first electrode plate 411 and the second electrode plate 413 at different positions on the inner wall of the pipe pile 2 come into contact, they can form a closed circuit.

[0080] S500: The pipe pile 2 is placed in the sliding limit assembly 120 by a crane and lowered into the borehole inside the central through hole 102;

[0081] S600: The pipe pile 2 is extended and pressed into the borehole by hammering. If the pipe pile 2 is tilted during the pressing process, the hammer 412 will remain vertical under the action of gravity, and the second electrode plate 413 will come into contact with the first electrode plate 411 in the tilt direction, thereby transmitting the tilt and deviation signal to the processor to realize the deviation detection.

[0082] S700: The processor controls the linear drive unit 113 in the pile adjustment unit 1 to perform telescopic movement, thereby controlling the sliding limit component 120 to tilt in the opposite direction to counteract the tilt state of the pile 2 and realize the offset adjustment.

[0083] S800: After the pipe pile 2 is completely lowered into the borehole, the movement of the fourth support ring 304 is controlled in reverse by the pressing component 313. As a result, under the action of the claw spring 312, the top block 307 of the inner wall locking positioning unit 3 releases the tight contact pressure with the pipe pile 2. Then, the equipment is disassembled to complete the integrated construction process of pipe pile 2 deviation detection and adjustment.
