Description

Technical Field

[0001] This invention relates to the technical field of pile foundation construction, and more particularly to a shock-absorbing and buffering device and its pile foundation. Background Technology

[0002] A corbel in a pile foundation is a horizontally cantilevered structural member welded or mechanically connected to the side of a concrete-filled steel pipe pile. Its primary function is to support the vertical loads transmitted from the superstructure and safely and effectively transfer them to the pile body. It is one of the key force transmission nodes in a pile foundation system and is widely used in bridge pier foundations, offshore platform jackets, large equipment foundations, industrial plant column foundations, wharf pile caps, and support points in bracing systems.

[0003] The corbel design for pile foundations is primarily static, focusing on bending strength, shear strength, and deformation control. Traditional design concepts typically treat the corbel as a component bearing static or quasi-static loads (the average effect of dead loads, live loads, and wind loads), with the corbel rigidly welded to the pile body to form a single integral node. It is precisely this "rigidity" and "static design thinking" of traditional corbels that reveals numerous shortcomings when facing complex dynamic loads or unexpected impacts.

[0004] (1) The root of the rigidly connected corbel is a typical area of ​​high stress concentration. Under dynamic horizontal loads such as earthquakes, wind vibrations, wave forces, vehicle impacts, and accidental construction impacts, the stress here increases sharply and changes rapidly. Existing technologies, such as stiffening ribs, grinding weld toes, and post-weld treatments, can improve this, but cannot effectively alleviate this fundamental weakness.

[0005] (2) Traditional pile foundation corbels lack an effective horizontal force buffer path. External impact energy, such as earthquakes, long-term wave current loads, and mechanical vibrations, is directly and rigidly transmitted to the pile body through the rigid joint, causing the pile-soil system to bear instantaneous peak loads and potentially inducing cascading failures of adjacent components. This is one of the most common failure modes of such joints in pile foundation engineering.

[0006] (3) It cannot adapt to the slow horizontal displacement caused by temperature deformation and foundation settlement. The forced constraint effect generates a non-negligible secondary internal force at the corbel-pile interface, further aggravating the stress deterioration.

[0007] (4) Traditional corbel structures lack built-in monitoring methods, making it difficult to provide early warning of node damage; and repairs require destructive dismantling, which is almost impossible to implement in harsh environments such as the ocean. Summary of the Invention

[0019] The present invention has the following advantages and beneficial effects compared with the prior art:

[0020] 1. The high-damping buffer plate of this invention can efficiently dissipate vibration energy through viscous deformation, reducing the kinetic energy transmitted to the pile body. Furthermore, the addition of nano-clay improves the rubber's hydrolysis resistance and impermeability.

Detailed Implementation

[0032] The invention's objective will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the implementation of the invention is not limited to the following embodiments.

[0033] like Figure 1 As shown, the pile foundation using a shock-absorbing device includes a shock-absorbing device 1, a corbel 2, a pile body 3, an oil pump 4, and a controller 5. The pile body 3 is vertically installed on the ground, and the corbel 2 is fixed to the outer wall of the pile body 3. The shock-absorbing device 1 is installed on top of the corbel 2. The shock-absorbing device 1 is connected to both the oil pump 4 and the controller 5, and the oil pump 4 is connected to the controller 5.

[0034] The vibration damping device 1 addresses the vulnerability and inadequacy of traditional welded brackets 2 under horizontal dynamic loads. It actively dissipates input structural vibration and impact energy, significantly reducing the response transmitted to the pile body and further structures. It prevents peak horizontal impact loads from directly impacting the weakest area of ​​the weld root, reduces the number of high-stress-amplitude dynamic cycles, and allows for controllable deformation of the structure under horizontal dynamic loads such as earthquakes, wind vibrations, and wave forces, preventing overall structural collapse. Furthermore, it allows real-time monitoring of the device's rotation speed and angle, with data available for early warning or assessment of seismic damage. The bracket 2 supports the vertical load from the superstructure and safely and effectively transmits it to the pile body. The pile body 3 provides support. The oil pump 4 pressurizes or depressurizes the vibration damping device 1. The controller 5 is a computer, which receives and analyzes the signals from the reflective photoelectric sensor 156 to determine the rotation speed and rotation angle of the rotating steel plate 13, thereby providing early warning for the shock absorption buffer device 1 and the corbel 2 of the pile body 3. When the controller 5 detects an abnormal signal, it controls the oil pump 4 to use the hydraulic jack 157 to lift and constrain the rotation of the rotating steel plate 13 and issue an alarm.

[0035] like Figures 2-6 As shown, the shock absorption and buffer device 1 includes a buffer structure, a waterproof elastic frame 14, and a base steel plate 15. The buffer structure includes a pressure-bearing steel plate 11, a high-damping buffer plate 12, and a rotating steel plate 13. The bottom of the base steel plate 15 is anchored to the top of the bracket 2 by screws 152. The base steel plate 15 is connected to the oil pump 4 by an oil pipe 1572 and to the controller 5 by a wire 1562. Both the oil pipe 1572 and the wire 1562 pass through the waterproof elastic frame 14. The oil pump 4 is connected to the controller 5 by the wire 1562. The outer frame of the base steel plate 15 is sealed to the lower end of the waterproof elastic frame 14, and the upper end of the waterproof elastic frame 14 is sealed to the lower outer periphery of the rotating steel plate 13. The bottom of the rotating steel plate 13 has a lifting part, a rotating part, and a reflecting part arranged sequentially from the center to the outer periphery. The lifting part of the base steel plate 15 is connected to the lifting part of the rotating steel plate 13. The rotating part of the rotating steel plate 13 is fixedly connected to the guide part of the base steel plate 15, and the reflecting part of the rotating steel plate 13 is connected to the detection part of the base steel plate 15. The top of the rotating steel plate 13 is locked to the bottom of the high-damping buffer plate 12, and the top of the high-damping buffer plate 12 is locked to the bottom of the pressure-bearing steel plate 11. The lifting part of the base steel plate 15 is connected to the oil pump 4, and the detection part of the base steel plate 15 is connected to the controller 5.

[0036] The buffer structure acts as a buffer against impact forces, thereby reducing the damage to the pile body 3 and the corbel 2. The bearing steel plate 11 is used to weld the external structure and bear pressure. The high-damping buffer plate 12 is made of high-damping rubber, which efficiently dissipates vibration energy through viscous deformation, reducing the kinetic energy transmitted to the pile body. The addition of nano-clay improves the rubber's hydrolysis resistance and impermeability. The rotating steel plate 13 can rotate when the shock-absorbing buffer device 1 is subjected to horizontal impact, thereby mitigating the horizontal impact force received by the structure. The waterproof elastic frame 14 is made of hydrogenated nitrile rubber and provides a sealing and waterproof function for the connection between the base steel plate 15 and the rotating steel plate 13. The base steel plate 15 guides the rotation of the rotating steel plate 13, detects the rotation speed and angle of the rotating steel plate 13, and provides vertical lifting for the rotating steel plate 13.

[0037] like Figure 5 and 6As shown, the base steel plate 15 includes a steel plate body, eight arc-shaped rails 153, eight roller rotating components 155, four reflective photoelectric sensors 156, and a hydraulic jack 157. Each roller rotating component 155 includes a set of rollers 1551, a rotating gripper 1552, a bogie 1553, and a bogie bolt 1554. Each reflective photoelectric sensor 156 includes a light source transceiver 1561 and a wire 1562. The hydraulic jack 157 includes a lifting jack 1571, an oil pipe 1572, and a jack handle 1573. A frame is provided on the top of the steel plate body, and the top of the frame is sealed to the bottom of the waterproof elastic frame 14. Four frames form a square recess. A circular slot 154 is located at the center of the square recess. A hydraulic jack 157 is installed in the circular slot 154. A lifting jack 1571 is connected to an oil pump 4 via an oil pipe 1572. A jack handle 1573 is connected to the lifting jack 1571. Eight limiting slots 151 are arranged along the circumference of the circular slot 154. The eight limiting slots 151 are fan-shaped and evenly distributed. A rib is provided between two adjacent limiting slots 151, for a total of seven ribs. The bottom of the eight limiting slots 151 is fixedly connected to the top of the bracket 2 by screws 152. Eight arc-shaped rails 153 are respectively set within the eight limiting slots 151 and located inside the screws 152. The centers of the arc-shaped rails 153, the eight limiting slots 151, and the circular slot 154 all overlap. One end of each bogie 1553 is mounted on a threaded hole 133 at the bottom of the rotating steel plate 13 via a bogie screw 1554. The other end of the bogie 1553 is rotatably connected to the top of a rotating gripper 1552, the lower end of which is rotatably connected to a roller assembly 1551, which is rotatably connected to an arc track 153. Four light source transceivers 1561 are respectively mounted at the four corners of the square groove and located outside the eight limiting slots 151. Each of the four light source transceivers 1561 is connected to one end of four wires 1562, and the other ends of the four wires 1562 pass through the preset holes in the waterproof elastic frame 14 and are then connected to the controller 5.

[0038] The steel plate body is made of Q345C steel plate material and is used to install and fix the arc track 153, the light source transceiver 1561, and the lifting jack 1571. The arc track 153 can accurately guide the rotation trajectory and allow the device above the roller assembly 1551 to make a certain horizontal displacement, further dispersing the horizontal impact stress. When the shock absorption buffer device 1 is subjected to horizontal impact, the rotating steel plate 13 drives the roller rotating component 155 to rotate, thereby alleviating the horizontal impact force on the structure. The reflective photoelectric sensor 156 is used to receive the light reflected by the reflector 132, thereby detecting the rotation speed and rotation angle of the rotating steel plate 13 and feeding it back to the controller 5. The hydraulic jack 157 is used to lift the rotating steel plate 13. The tires of the roller assembly 1551 are made of high-strength rubber, allowing the rotating steel plate 13 to rotate relative to the base steel plate 15. The rotating gripper 1552 is used to install the roller assembly 1551 at one end of the bogie 1553. The bogie 1553 is used to rotate the gripper 1552 relative to the rotating steel plate 13, allowing the roller assembly 1551 to move along the arc track 153. The light transceiver 1561 receives the light reflected from the reflector 132 and then feeds it back to the controller 5. The wire 1562 supplies power to the light transceiver 1561 and transmits signals; the lifting jack 1571 is used to lift or lower the rotating steel plate 13. The oil pipe 1572 can withstand a certain oil pressure and is used to transmit hydraulic oil, thereby controlling the piston action of the lifting jack 1571. The jack handle 1573 is inserted into the limiting hole 1541 in the circular slot 154. The lifting jack 1571 is rotated so that the jack handle 1573 rotates into the circular slot 154. Finally, a dense rubber block is inserted into the limiting hole 1541 to secure the lifting jack 1571.

[0039] like Figures 3-5As shown, the bottom of the pressure-bearing steel plate 11 has eleven trapezoidal grooves 111 perpendicular to its axial direction. These eleven grooves are arranged sequentially and parallel to each other, with equal spacing between adjacent grooves. The high-damping buffer plate 12 has longitudinal and transverse spiral steel wire mesh 122 embedded inside, and 2% nano-clay by mass is added. The top and bottom surfaces of the high-damping buffer plate 12 each have eleven rubber trapezoidal protrusions 121 perpendicular to its axial direction. These protrusions are arranged sequentially and parallel to each other, with equal spacing between adjacent protrusions. The eleven protrusions 121 on the top surface are embedded into the eleven pressure-bearing steel plate trapezoidal grooves 111. The top of the rotating steel plate 13 has eleven rotating steel plate trapezoidal grooves 131 perpendicular to its axial direction. These grooves are arranged sequentially and parallel to each other, with equal spacing between adjacent grooves. Eleven rubber trapezoidal protrusions 121 at the bottom are respectively embedded in eleven trapezoidal grooves 131 of the rotating steel plate. Eight threaded holes 133 are provided at the bottom of the rotating steel plate 13, forming a circle. The bogie screws 1554 of the roller rotating component 155 are installed in the eight threaded holes 133. Four reflective sheets 132 are provided on the outer side of the eight threaded holes 133, each corresponding to a light source transceiver 1561 of one of the four reflective photoelectric sensors 156.

[0040] The longitudinal and transverse spiral steel wire mesh 122 is used to bidirectionally restrain the rubber, preventing tearing during large deformations. The rubber trapezoidal protrusions 121, the pressure-bearing steel plate trapezoidal grooves 111, and the rotating steel plate trapezoidal grooves 131 enhance the structure's shear resistance, prevent interlayer separation, and solve the problem of rubber-steel plate interface slippage under large loads, while allowing for small horizontal displacements of the structure under load. The reflective sheet 132, made of polished metal, is used to reflect the light emitted by the reflective photoelectric sensor 156.

[0041] Installation process instructions for pile foundations using vibration damping devices:

[0042] Step 1: First, install four reflective photoelectric sensors 156 and one hydraulic jack 157 on the steel plate body. Then, install the steel plate body on the top surface of the bracket 2 with screws 152. Connect the hydraulic jack 157 to the oil pump 4. Connect the oil pump 4 and the reflective photoelectric sensors 156 to the controller 5. Finally, place the eight roller rotating parts 155 into the eight arc tracks 153 in sequence.

[0043] Step 2: Eleven trapezoidal grooves 131 are set on the upper surface of the rotating steel plate 13. Then, four reflective sheets 132 are pre-embedded on the outside of the trapezoidal grooves 131. The four reflective sheets 132 correspond one-to-one with the positions of the light source transceivers 1561 of the four reflective photoelectric sensors 156. The controller 5 controls the piston of the hydraulic jack 157 to lift the rotating steel plate 13 through the oil pump 4. The bogie screws 1554 on the eight roller rotating parts 155 at the bottom of the rotating steel plate 13 are anchored. The controller 5 controls the piston of the hydraulic jack 157 to fall back through the oil pump 4.

[0044] Step 3: The upper and lower surfaces of the waterproof elastic frame 14 are vulcanized. The upper surface of the waterproof elastic frame 14 is sealed to the bottom surface of the rotating steel plate 13, and the lower surface of the waterproof elastic frame 14 is sealed to the frame of the base steel plate 15. The oil pipe 1572 of the hydraulic jack 157 and the wire 1562 of the reflective photoelectric sensor 156 both pass through the preset holes of the waterproof elastic frame 14.

[0045] Step 4: Embed the longitudinal and transverse spiral steel wire mesh into the high-damping rubber to form a high-damping buffer plate 12. The top and bottom surfaces of the high-damping buffer plate 12 are provided with rubber trapezoidal protrusions 121. The rubber trapezoidal protrusions 121 on the bottom surface are embedded into the rotating steel plate trapezoidal grooves 131 on the top surface of the rotating steel plate 13, thereby achieving mutual locking between the high-damping buffer plate 12 and the rotating steel plate 13.

[0046] Step 5: The rubber trapezoidal protrusion 121 on the top surface is embedded into the trapezoidal groove 111 on the bottom surface of the pressure-bearing steel plate 11, thereby achieving mutual locking between the high-damping buffer plate 12 and the pressure-bearing steel plate 11.

[0047] Step 6: The external structure can be welded to the pressure-bearing steel plate 11 to complete the installation of the pile foundation using the shock-absorbing buffer device;

[0048] Step 7: Based on the site environment and construction conditions, adjust the piston lifting buffer structure of hydraulic jack 157.

[0049] Step 8: When the controller 5 receives an abnormality from the light source transceiver 1561, the controller 5 issues an early warning and automatically operates the oil pump 4 to lift the piston of the hydraulic jack 157 to rotate the steel plate 13, thereby constraining the rotation of the steel plate 13.

[0050] Advantages of using pile foundations with vibration damping devices: Pile foundations using vibration damping devices transform traditional pile foundations from rigid force transmission points into intelligent vibration damping hubs, possessing four functions: high energy efficiency, displacement adaptability, measurable condition, and controllable damage. Pile foundations using vibration damping devices can address the vulnerability and inadequacy of the top surface of the corbel 2 in traditional welded pile foundations under horizontal dynamic loads. They can actively dissipate input structural vibration and impact energy, significantly reducing the response transmitted to the pile body 3 and further structures, preventing peak horizontal impact loads from directly impacting the weakest area of ​​the weld root, reducing the number of high-stress amplitude dynamic cycles, and allowing the structure to undergo controllable deformation under horizontal dynamic loads such as earthquakes, wind vibrations, and wave forces, avoiding overall structural collapse. Furthermore, the rotation speed and angle of the vibration damping device 1 can be monitored in real time, and these parameters can be used for early warning or assessment of seismic damage.

Any other changes or equivalent substitutions made without departing from the technical solution of the present invention are included within the protection scope of the present invention.
