Description

Technical Field

[0001] This invention belongs to the field of pile foundation technology, and in particular to a prefabricated vibration reduction and reinforcement anti-uplift pile based on inertial capacitive damping and its installation method. Background Technology

[0002] Uplift pile foundations are used in construction projects where the underground structure is below the surrounding soil water level. The piles are driven to counteract the buoyancy of the water in the soil. Their primary mechanism relies on the friction between the pile and the soil layer to resist axial tensile forces.

[0003] In the field of modern construction engineering, tension pile foundations, as the core structure bearing uplift loads, directly affect the overall safety and stability of buildings and are widely used in important projects such as high-rise buildings, cross-sea bridges, and towering wind turbine towers. With the continuous expansion of infrastructure construction in my country, more and more engineering projects are extending to high-intensity earthquake zones, soft soil areas, and regions with complex geological conditions. Traditional tension pile foundations are facing unprecedented challenges in this process.

[0004] Currently, traditional tension pile foundations mainly adopt reinforced concrete cast-in-place piles or precast piles. For example, Chinese patent CN212001053U discloses a precast hollow tension pile, published on November 24, 2020. It includes a pile body and a gradually opening pile tip. The gradually opening pile tip has a conical tip. The pile body has a hollow structure for filling with concrete. The upper part of the hollow structure is a frustum-shaped structure, and the lower part is a cylindrical structure. The diameter of the hole in the frustum-shaped structure increases from top to bottom. Several semi-circular grooves are provided on the side wall of the frustum-shaped structure.

[0005] The seismic performance of this type of foundation mainly relies on the skin-to-soil friction and the rigid constraints of the pile material. In high-intensity earthquake zones, the intense vibrations caused by seismic waves result in severe soil deformation, leading to significant fluctuations and difficulty in maintaining stable skin-to-soil friction. Simultaneously, under high-frequency dynamic load impacts, the pile material, lacking an effective buffering mechanism due to rigid constraints, is prone to stress concentration, resulting in pile cracking and fracture. In soft soil areas, the low strength and high compressibility of soft soil make it difficult to fully utilize the skin-to-soil friction. Under dynamic loads such as strong winds, tension pile foundations are prone to horizontal displacement and tilting, and in severe cases, even foundation slippage, directly threatening the safety and stability of the superstructure and significantly weakening the overall structural stability.

[0006] Under long-term cyclic loading, the pile-soil interface of traditional tension piles is continuously subjected to repeated stress, leading to the accumulation of fatigue damage. This fatigue damage alters the contact characteristics between the pile and the soil, reducing the contact area and frictional resistance, which in turn causes a significant decrease in the bearing capacity of the tension pile foundation, drastically shortening the service life of the structure and increasing the cost of later maintenance and repair.

[0007] In recent years, prefabricated anti-tension pile technology has been gradually applied in engineering construction due to its advantages such as high construction efficiency and strong quality control.

[0008] For example, Chinese patent document CN102561336A, published on July 11, 2012, entitled "A Multi-Nut Seat Assembled Anti-Pull-Out Pile," discloses a multi-nut seat assembled anti-pull-out pile, which includes a pile body and multiple L-shaped anti-rotation connecting plates. A square end plate is provided at the end of the pile body. At least two large groups of nut seats are arranged sequentially in the pile body and along the end plate towards the middle of the pile body. There is a gap between two adjacent large groups of nut seats. Each large group of nut seats is divided into four subgroups, and each subgroup has two nut seats. Each of the four sides of the end plate corresponds to a nut seat subgroup. Two nut seats located in adjacent subgroups and in adjacent positions are respectively connected to the two ends of an L-shaped anti-rotation connecting plate. At the same time, the two ends of this anti-rotation connecting plate extend along the end plate towards the middle of the pile body and are connected to the corresponding nut seats in the adjacent large groups. This anti-tension pile increases the connection method between two anti-tension piles, which can prevent the connection between the two anti-tension piles from being damaged by groundwater, thereby improving the tensile strength and bending strength between the two end plates, and thus improving the overall performance of the pile.

[0009] However, the existing design of connection nodes for prefabricated tension piles still has many shortcomings: On the one hand, the connection nodes mostly adopt bolt connections, welding and other methods. These connection forms are difficult to match the mechanical performance of the whole cast-in-place structure. Under complex load conditions, stress concentration is prone to occur at the connection nodes, leading to node failure and affecting the overall working performance of the tensile pile foundation.

[0010] On the other hand, the existing connection nodes have limited energy dissipation capacity. Under dynamic loads such as earthquakes, they cannot effectively dissipate energy and cannot meet the vibration reduction and reinforcement requirements under complex working conditions, thus limiting the widespread application of prefabricated anti-uplift pile technology in high-requirement projects.

[0011] From a design perspective, current designs for tension pile foundations often focus on static mechanical performance analysis, with relatively insufficient research on inertial effects and energy dissipation mechanisms under dynamic loads such as earthquakes and strong winds.

[0012] The paper "Distribution Law of Earth Pressure Around Expanded-Base Tension Piles," published in the second issue of Engineering Investigation in 2025 on February 1, 2025, conducted earth pressure tests on the vicinity of the expanded-base section of tension piles and performed three-dimensional modeling analysis using numerical analysis software. However, this analysis is based on the premise that there are no dynamic loads, which deviates somewhat from the actual application conditions of tension piles.

[0013] The paper "Numerical Simulation Study on Failure Mode of Tension-Resistant Piles in Soil and Rock Foundations," published in the 6th issue of *Jiangxi Building Materials* in 2024 (published on June 30, 2024), analyzes the failure mode and influencing factors of tension-resistant piles in soil and rock foundations using numerical simulation. The results show significant differences in the stress and deformation of tension-resistant piles under vertical and dynamic loads. Specifically, under vertical static load, the axial force of the tension-resistant pile is approximately 80 kN, the bending moment is approximately 20 kN·m, the vertical displacement is approximately 2 mm, and the lateral displacement is approximately 1 mm. Under dynamic load, these values ​​increase to 120 kN and 30 kN·m, respectively. The vertical displacement increases from 2 mm to 3 mm, and the lateral displacement increases from 1 mm to 1.5 mm; the stress and deformation of the tension-resistant pile become more significant. This indicates that factors such as load magnitude, soil properties, and pile shape have a significant impact on the failure mode of tension-resistant piles.

[0014] In practical engineering, dynamic loads are characterized by high frequency, short duration, and concentrated energy, resulting in significant differences in structural response under dynamic loads compared to static loads. Due to a lack of in-depth research on the characteristics of dynamic loads, existing designs for tension pile foundations struggle to fully exploit and utilize the structure's potential mechanical properties, hindering optimized design and efficient utilization.

[0015] As an emerging vibration control method, inertial capacitive damping technology can significantly amplify the effective inertial force of a structure by introducing additional inertial mass effect, thereby greatly improving vibration control efficiency.

[0016] An inertial capacitive damper typically consists of an inertial container, a damper, and an additional mass block. When the structure vibrates under external excitation, the inertial container converts the input acceleration into inertial force through its internal flywheel or similar mechanism, and works together with the damper to dissipate the vibration energy of the structure.

[0017] The specific working principle is as follows: When the structure vibrates, the additional mass block moves accordingly and is connected to the main structure through the inertial container.

[0018] The inertial container generates a corresponding inertial force based on the acceleration of the added mass block, and this inertial force is opposite to the vibration direction of the main structure.

[0019] The damper is responsible for absorbing and dissipating the energy difference between the inertial force generated by the inertial container and the vibration of the main structure.

[0020] By adjusting the parameters of the inertial container (such as the mass of the flywheel, moment of inertia, etc.), precise adjustment of vibration control can be achieved.

[0021] In the field of vibration control of building superstructures, inertial capacitive dampers have achieved certain application results, successfully reducing the structural response under earthquakes, wind-induced vibrations, and other effects. Furthermore, there have been numerous reports on the vibration reduction principles of inertial capacitive dampers. For example, the paper "Analysis and Research on Energy Dissipation and Vibration Reduction Mechanism of Inertial Capacitive Dampers" published in Volume 43, Issue 23 of *Vibration and Shock*, based on a simplified single-degree-of-freedom vibration reduction structure, uses dynamic theory to derive expressions for the additional equivalent stiffness coefficient and damping coefficient provided to the structure by inertial capacitive dampers and tuned viscous mass dampers under dynamic conditions.

[0022] However, the application of inertial-capacitive damping technology in the crucial field of tension pile foundations is currently lacking. How to organically combine the principle of inertial-capacitive damping with prefabricated tension pile technology to develop a new type of tension pile foundation that combines efficient vibration reduction performance with rapid assembly characteristics, in order to meet the stringent requirements of modern engineering construction for high safety and high stability of foundation structures under complex working conditions, has become a key technical challenge that urgently needs to be overcome in the current engineering field. Summary of the Invention

[0075] This technical solution further addresses the technical problem of how to reduce the resistance of the inserted soil.

[0076] Secondly, the present invention also provides an installation method for prefabricated vibration-damping and tension-resistant piles based on inertial-capacitive damping, for installing the aforementioned prefabricated vibration-damping and tension-resistant piles, the installation method comprising: S1. Connect the torsion connection device, gear transmission device, spike anti-pull device and pile head according to the design requirements to form the pile body; S2. Insert the pile into the soil; S3. Rotate the torsion shaft to insert the spike into the soil; S4. Connect the inertial capacitance multi-directional vibration damping device to the torsional connection device.

[0077] In some embodiments, the pile is inserted into the soil using a hammering method, a vibration method, or a pile driving method.

[0078] The working principle of this invention is as follows: The prefabricated vibration-damping and anti-uplift pile provided by this invention is placed at the selected site. The pile head, anti-uplift spike device, gear transmission device, and torsion connection device are assembled according to the pile foundation design length, burial depth, and soil thickness. The assembled pile body is inserted into the soil using methods such as hammering, vibration, or pile driving. The torsion bar of the torsion connection device is rotated, causing the torsion main shaft to rotate. The rotation of the torsion main shaft drives the main gear of the gear transmission device. The main gear, constrained by the secondary gear and the toothed third housing, rotates around its own axis. The main gear transmits the torsional torque to the anti-uplift spike device through the cross-joint.

[0079] The pull-out resisting spindle of the spike device rotates around its axis under the drive of the main gear. A hinge located on the outside of the pull-out resisting spindle causes the root of the spike to twist. A pre-drilled hole in the center of the spike penetrates a vertical rod, which is connected to a fourth outer shell at the top and bottom. This guides the spike to expand outward, allowing it to penetrate the soil and achieve the pull-out resisting effect for foundation reinforcement.

[0080] The inertial-capacitance multi-directional vibration damping device is bolted to the torsion connection device on the upper part of the completed pile body, thus connecting it to the pile body. The upper connecting plate of the inertial-capacitance multi-directional vibration damping device has pre-drilled bolt holes for connection to the superstructure. When the superstructure experiences vibration or external disturbance, the piston damper connected by a ball joint around the connecting plate reduces the horizontal displacement of the foundation. The vertical displacement of the connecting plate is constrained by a rubber damping pad, a spring, and the inertial-capacitance damping assembly. Compression or tension of the inertial-capacitance damping assembly causes the push rod to move relative to the inner cylinder, creating a pressure difference between the inner and outer cylinders. This causes the viscous damping fluid in the outer cylinder to flow in the curved tube, amplifying inertia.

[0081] When the viscous damping fluid flows through the damping mesh inside the curved tube, it decelerates, thus dissipating energy. When the structural vibration or disturbance ends, the rubber damping pad, spring, and inertial capacitive damping assembly can recover their deformation, achieving a self-recovery function.

[0082] Compared with existing technologies, the prefabricated vibration reduction and reinforcement anti-uplift pile based on inertial capacitive damping provided by this invention has the following beneficial effects: This invention proposes a prefabricated vibration-damping and reinforcement anti-uplift pile based on inertial capacitive damping, which can enhance the anti-uplift anchoring force. The spike anti-uplift device drives the spike to expand and insert into the soil through gear transmission. Compared with traditional anti-uplift piles, it significantly increases the contact area and interlocking force with the soil, effectively resisting the uplift load of the building and ensuring structural safety.

[0083] This invention proposes a prefabricated vibration-damping and tension-resistant pile based on inertial-capacitive damping, which can improve applicability to complex geological conditions. The splicing length and embedment depth of the pile can be flexibly adjusted according to different site geological conditions. With the adaptive expansion function of the spike device, it can better adapt to soil properties in soft soil, sandy soil and other weak strata, avoiding foundation instability problems caused by insufficient soil strength.

[0084] This invention proposes a prefabricated vibration-damping and tension-resistant pile based on inertial-capacitive damping, which enables rapid prefabricated construction. The prefabricated design of each component requires only on-site assembly followed by hammering, vibration, or pile driving, reducing the concrete pouring and curing time of traditional cast-in-place piles and significantly shortening the project cycle.

[0085] This invention proposes a prefabricated vibration-damping and uplift-resistant pile based on inertial capacitive damping, which can reduce the impact on the construction environment. Prefabricated construction reduces on-site wet work and construction waste generation, reduces dust and noise pollution, and also reduces energy consumption during concrete mixing and transportation, which is in line with the concept of green construction and is friendly to the surrounding environment.

[0086] This invention proposes a prefabricated vibration-damping and anti-uplift pile based on inertial capacitive damping, which can precisely transmit and control torque. The precise design of the gear transmission device ensures efficient and stable torque transmission from the torsional connection device to the spike anti-uplift device, avoiding torque loss and transmission deviation, ensuring that the spike expands accurately according to design requirements, and improving the controllability of foundation construction quality.

[0087] This invention proposes a prefabricated vibration reduction and reinforcement anti-uplift pile based on inertial capacitive damping, which can achieve multi-directional synergistic vibration reduction capability. The inertial capacitive multi-directional vibration reduction device works synergistically in the horizontal and vertical directions. The horizontal piston damper, the vertical rubber damping pad, the spring, and the inertial capacitive damping device work together to effectively attenuate vibrations in different directions.

[0088] This invention proposes a prefabricated vibration reduction and reinforcement anti-uplift pile based on inertial capacitive damping, which can efficiently dissipate energy through inertial amplification. The inertial capacitive damping device generates a pressure difference through the relative movement of the push rod and the inner and outer cylinders, causing the viscous damping fluid to flow in the curved tube to achieve an inertial amplification effect. Compared with traditional dampers, under the same vibration conditions, the energy dissipation efficiency is improved, the vibration energy is quickly consumed, and the vibration amplitude of the structure is reduced.

[0089] This invention proposes a prefabricated vibration-damping and reinforcement anti-uplift pile based on inertial capacitive damping, which exhibits excellent structural self-restoring performance. After vibration ends, the rubber damping pad, spring, and inertial capacitive damping components rapidly return to their original shape due to their own elastic deformation characteristics, resulting in almost zero residual deformation of the foundation structure, reducing structural damage accumulation, extending service life, and lowering subsequent maintenance costs.

[0090] This invention proposes a prefabricated vibration-damping and anti-uplift pile based on inertial-capacitive damping, which can improve the overall stability of the structure. The coordinated operation of the gear transmission device, the spike anti-uplift device, and the inertial-capacitive multi-directional vibration damping device enhances the mechanical connection between the pile body and the soil and the superstructure, improves the overall stability of the foundation structure under complex loads, and effectively suppresses structural swaying and tilting.

[0091] This invention proposes a prefabricated vibration-damping and uplift-resistant pile based on inertial-capacitive damping, which facilitates later maintenance and upgrades. Each component of the prefabricated structure is installed independently; if a component is damaged, it can be quickly disassembled and replaced without requiring large-scale modifications to the entire foundation. Furthermore, the vibration damping device can be upgraded or more suitable spike components can be replaced according to project requirements, improving foundation performance.

[0092] This invention proposes a prefabricated vibration-damping and uplift-resistant pile based on inertial capacitive damping, which can save on building material costs. Through optimized design, unnecessary use of pile materials is reduced while ensuring foundation bearing capacity and vibration reduction performance. For example, after the spike device enhances the uplift resistance, the pile diameter or length can be appropriately reduced, thereby reducing the amount of concrete, steel, and other materials used and saving costs.

[0093] This invention proposes a prefabricated vibration reduction and reinforcement anti-uplift pile based on inertial capacitive damping, which can promote the development of building industrialization. The prefabricated design concept of this invention drives the standardization and modularization of building foundation construction, which is conducive to the advancement of industrialized building production and construction technology, and improves the overall technical level and production efficiency of the construction industry.

[0108] Example 1 This embodiment provides a prefabricated vibration-damping and uplift-resistant pile based on inertial-capacitive damping, including: Inertial capacitance multi-directional vibration damping device 1, such as Figure 1 As shown, the inertial-capacitive multi-directional vibration damping device 1 has a first outer shell 1-3 on its outer side. Multiple piston dampers 1-2 are connected to the upper inner wall of the first outer shell 1-3 by ball joints. A connecting plate 1-1 is provided inside the first outer shell 1-3, and all the piston dampers 1-2 are connected to the outer wall of the connecting plate 1-1 by ball joints. The upper part of the connecting plate 1-1 is connected to the upper structure, and the lower part of the connecting plate 1-1 is connected to the inertial-capacitive damping assembly. A base plate 1-6 is provided below the inertial-capacitive damping assembly, and the base plate 1-6 is fixedly connected to the first outer shell 1-3. An elastic component is provided between the connecting plate 1-1 and the base plate 1-6.

[0109] The first outer shell 1-3 is a cylindrical structure with a cylindrical through hole or a space communicating with the outside. Vertical bolt holes are provided in the side wall of the first outer shell 1-3 for connecting with other structural components. The bolt holes can be plain holes or threaded holes, preferably plain holes.

[0110] The inner wall above the first outer shell 1-3 refers to the inner wall surface of the first outer shell 1-3 and the position near the upper end face of the first outer shell 1-3. This position is connected to multiple piston dampers 1-2 by ball joints. Specifically, the inner wall of the first outer shell 1-3 has multiple spherical grooves, and the ball joints are connected in the spherical grooves. The other end of the ball joints is connected to the piston dampers 1-2.

[0111] Multiple piston dampers 1-2 refer to the inclusion of more than two piston dampers 1-2 in this embodiment, specifically 10, which are evenly distributed along the circumference of the connecting plate 1-1. In other embodiments, the number of piston dampers 1-2 can be simply replaced with 8, 6, 12, etc.

[0112] The connecting plate 1-1 inside the first outer shell 1-3 is circular. The center of the circular connecting plate 1-1 is located on the axis of the first outer shell 1-3. The outer wall of the connecting plate 1-1 is connected to all the piston dampers 1-2 by ball joints. Specifically, the outer wall of the connecting plate 1-1 is provided with multiple spherical grooves, and the ball joints are connected in the spherical grooves. The other end of the ball joints is connected to the piston dampers 1-2.

[0113] Bolt holes are provided on the connecting plate 1-1, and the connecting plate 1-1 is connected to the upper building through the bolt holes. The number of bolt holes is set according to design requirements, and preferably four bolt holes are arranged in an array.

[0114] In addition, the base plate 1-6 is circular, and the outer edge of the base plate 1-6 is aligned with the outer wall of the first outer shell 1-3. That is, the base plate 1-6 closes the lower surface of the first outer shell 1-3, and the first outer shell 1-3 is fixedly connected to the base plate 1-6, for example, by welding or integral molding.

[0115] The inertial-capacitive damping assembly includes an outer cylinder 1-11 disposed on the lower surface of the connecting plate 1-1 and a push rod 1-7 disposed on the upper surface of the base plate 1-6. The lower end of the outer cylinder 1-11 is connected to a sealing cover 1-8, and an inner cylinder 1-9 is disposed above the sealing cover 1-8. The inner cylinder 1-9 is fitted inside the outer cylinder 1-11. The upper end of the push rod 1-7 is inserted into the inner cylinder 1-9 and can reciprocate within the inner cylinder 1-9. The outer cylinder 1-11, the inner cylinder 1-9, the sealing cover 1-8, and the connecting plate 1-1 form a first enclosed space, and the inner cylinder 1-9 and the upper surface of the push rod 1-7 form a second enclosed space. The first enclosed space is filled with viscous damping fluid. A bent tube 1-10 is also provided in the first enclosed space. The bent tube 1-10 has a through hole inside, and one end of the through hole is connected to the second enclosed space, and the other end of the through hole is connected to the first enclosed space.

[0116] The outer cylinder 1-11 is preferably cylindrical, and the outer cylinder 1-11 and the connecting plate 1-1 are preferably connected by welding to improve sealing performance. The inner cylinder 1-9 is preferably cylindrical, and the contact surface between the inner cylinder 1-9 and the push rod 1-7 is the sealing surface. To improve sealing performance, a sealing ring can be added to the contact surface between the inner cylinder 1-9 and the push rod 1-7.

[0117] Viscous damping fluid is an oily liquid that attenuates mechanical kinetic energy through viscous resistance, primarily used to shorten the time of mechanical oscillation or movement. This liquid is typically pale yellow and composed of various water-soluble additives; its viscosity coefficient and other technical parameters are adjusted according to the application scenario.

[0118] In this embodiment, the bent tube 1-10 is an S-shaped tube. Specifically, one end of the bent tube 1-10 is connected to the upper wall of the inner cylinder 1-9, thereby enabling the through hole to connect to the second closed space; the bent tube 1-10 extends upward from the upper wall of the inner cylinder 1-9, bends and then extends downward, and then bends and then extends upward again.

[0119] To improve viscous resistance, multiple damping meshes are installed inside the bent tube 1-10. Specifically, one, two, three, or other damping meshes can be installed inside a single bent tube 1-10. The damping meshes can be made of materials such as stainless steel or rubber, with the specific material selected based on the application scenario and requirements. The damping meshes generally employ a multi-layer structure, with an inner damping layer that effectively absorbs impact energy; an outer wear-resistant layer that prevents material wear; and a middle reinforcing layer that increases the material's strength and stability.

[0120] There are multiple bent tubes 1-10, and the multiple bent tubes 1-10 are evenly distributed along the circumference of the inner cylinder 1-9.

[0121] The uniformly distributed bent tubes 1-10 enable this embodiment to provide equal viscous resistance at all locations, thereby making it suitable for vibration reduction under external forces in all directions.

[0122] In addition, the elastic component includes a first elastic component and a second elastic component, the first elastic component being wound around the outer periphery of the inertial-capacitive damping assembly, and the second elastic component being sleeved on the outer periphery of the first elastic component.

[0123] The first elastic component is spring 1-5. In other embodiments, the first elastic component may be replaced with other elastic components, such as rubber damping pads, diaphragms, bellows, etc.

[0124] In some embodiments, the second elastic component is a rubber damping pad 1-4. Similarly, in other embodiments, the second elastic component can be replaced with other elastic components, such as a spring, diaphragm, bellows, etc.

[0125] When the building above is subjected to external forces and vibrates, the resulting disturbances include horizontal and vertical displacements, as well as rotational torque. For horizontal displacement, multiple piston dampers 1-2 connected by connecting plate 1-1 are used for energy dissipation and vibration reduction. When connecting plate 1-1 moves horizontally along with the structure above, the pistons inside the piston dampers 1-2, which are under tension or compression, move to dissipate energy, thereby reducing the horizontal displacement of the structural foundation.

[0126] Regarding the rotational torque, when the connecting plate 1-1 twists along with the upper structure, since the piston damper 1-2, the connecting plate 1-1, and the first outer shell 1-3 are all connected by ball joints, the piston damper 1-2 is subjected to torsional tension. The piston movement inside the piston damper 1-2 dissipates energy and reduces the torsional torque of the structural foundation.

[0127] For vertical displacement, when the connecting plate 1-1 moves up and down following the upper structure, the outer cylinder 1-11 moves up and down with the connecting plate 1-1, while the push rod 1-7 remains relatively stationary due to the fixation of the base plate 1-6. When the outer cylinder 1-11 moves up and down, the push rod 1-7 reciprocates relative to the inner cylinder 1-9, creating a pressure difference between the inner cylinder 1-9 and the outer cylinder 1-11. This causes the viscous damping fluid in the outer cylinder 1-11 to flow in the curved tube 1-10, amplifying inertia. When the viscous damping fluid flows through the damping mesh in the curved tube 1-10, it is further decelerated, achieving energy dissipation.

[0128] Furthermore, the inertial-capacitive multi-directional vibration damping device can reduce or even prevent external force interference from all directions of the upper structural foundation. When the vibration or disturbance of the structural foundation ends, the rubber damping pads 1-4, springs 1-5, and inertial-capacitive damping components can recover their deformation and achieve self-recovery.

[0129] Example 2 This embodiment provides a prefabricated vibration-damping and uplift-resistant pile based on inertial-capacitive damping, including: Inertial capacitance multi-directional vibration damping device 1, such as Figure 1 As shown, the inertial-capacitive multi-directional vibration damping device 1 has a first outer shell 1-3 on its outer side. Multiple piston dampers 1-2 are connected to the upper inner wall of the first outer shell 1-3 by ball joints. A connecting plate 1-1 is provided inside the first outer shell 1-3, and all the piston dampers 1-2 are connected to the outer wall of the connecting plate 1-1 by ball joints. The upper part of the connecting plate 1-1 is connected to the upper structure, and the lower part of the connecting plate 1-1 is connected to the inertial-capacitive damping assembly. A base plate 1-6 is provided below the inertial-capacitive damping assembly, and the base plate 1-6 is fixedly connected to the first outer shell 1-3. An elastic component is provided between the connecting plate 1-1 and the base plate 1-6.

[0130] The first outer shell 1-3 is a cylindrical structure with a cylindrical through hole or a space communicating with the outside. Vertical bolt holes are provided in the side wall of the first outer shell 1-3 for connecting with other structural components. The bolt holes can be plain holes or threaded holes, preferably plain holes.

[0131] The inner wall above the first outer shell 1-3 refers to the inner wall surface of the first outer shell 1-3 and the position near the upper end face of the first outer shell 1-3. This position is connected to multiple piston dampers 1-2 by ball joints. Specifically, the inner wall of the first outer shell 1-3 has multiple spherical grooves, and the ball joints are connected in the spherical grooves. The other end of the ball joints is connected to the piston dampers 1-2.

[0132] Multiple piston dampers 1-2 refer to the inclusion of more than two piston dampers 1-2 in this embodiment, specifically 10, which are evenly distributed along the circumference of the connecting plate 1-1. In other embodiments, the number of piston dampers 1-2 can be simply replaced with 8, 6, 12, etc.

[0133] The connecting plate 1-1 inside the first outer shell 1-3 is circular. The center of the circular connecting plate 1-1 is located on the axis of the first outer shell 1-3. The outer wall of the connecting plate 1-1 is connected to all the piston dampers 1-2 by ball joints. Specifically, the outer wall of the connecting plate 1-1 is provided with multiple spherical grooves, and the ball joints are connected in the spherical grooves. The other end of the ball joints is connected to the piston dampers 1-2.

[0134] Bolt holes are provided on the connecting plate 1-1, and the connecting plate 1-1 is connected to the upper building through the bolt holes. The number of bolt holes is set according to design requirements, and preferably four bolt holes are arranged in an array.

[0135] In addition, the base plate 1-6 is circular, and the outer edge of the base plate 1-6 is aligned with the outer wall of the first outer shell 1-3. That is, the base plate 1-6 closes the lower surface of the first outer shell 1-3, and the first outer shell 1-3 is fixedly connected to the base plate 1-6, for example, by welding or integral molding.

[0136] The inertial-capacitive damping assembly includes an outer cylinder 1-11 disposed on the lower surface of the connecting plate 1-1 and a push rod 1-7 disposed on the upper surface of the base plate 1-6. The lower end of the outer cylinder 1-11 is connected to a sealing cover 1-8, and an inner cylinder 1-9 is disposed above the sealing cover 1-8. The inner cylinder 1-9 is fitted inside the outer cylinder 1-11. The upper end of the push rod 1-7 is inserted into the inner cylinder 1-9 and can reciprocate within the inner cylinder 1-9. The outer cylinder 1-11, the inner cylinder 1-9, the sealing cover 1-8, and the connecting plate 1-1 form a first enclosed space, and the inner cylinder 1-9 and the upper surface of the push rod 1-7 form a second enclosed space. The first enclosed space is filled with viscous damping fluid. A bent tube 1-10 is also provided in the first enclosed space. The bent tube 1-10 has a through hole inside, and one end of the through hole is connected to the second enclosed space, and the other end of the through hole is connected to the first enclosed space.

[0137] The outer cylinder 1-11 is preferably cylindrical, and the outer cylinder 1-11 and the connecting plate 1-1 are preferably connected by welding to improve sealing performance. The inner cylinder 1-9 is preferably cylindrical, and the contact surface between the inner cylinder 1-9 and the push rod 1-7 is the sealing surface. To improve sealing performance, a sealing ring can be added to the contact surface between the inner cylinder 1-9 and the push rod 1-7.

[0138] Viscous damping fluid is an oily liquid that attenuates mechanical kinetic energy through viscous resistance, primarily used to shorten the time of mechanical oscillation or movement. This liquid is typically pale yellow and composed of various water-soluble additives; its viscosity coefficient and other technical parameters are adjusted according to the application scenario.

[0139] In this embodiment, the bent tube 1-10 is an S-shaped tube. Specifically, one end of the bent tube 1-10 is connected to the upper wall of the inner cylinder 1-9, thereby enabling the through hole to connect to the second closed space; the bent tube 1-10 extends upward from the upper wall of the inner cylinder 1-9, bends and then extends downward, and then bends and then extends upward again.

[0140] To improve viscous resistance, multiple damping meshes are installed inside the bent tube 1-10. Specifically, one, two, three, or other damping meshes can be installed inside a single bent tube 1-10. The damping meshes can be made of materials such as stainless steel or rubber, with the specific material selected based on the application scenario and requirements. The damping meshes generally employ a multi-layer structure, with an inner damping layer that effectively absorbs impact energy; an outer wear-resistant layer that prevents material wear; and a middle reinforcing layer that increases the material's strength and stability.

[0141] There are multiple bent tubes 1-10, and the multiple bent tubes 1-10 are evenly distributed along the circumference of the inner cylinder 1-9.

[0142] The uniformly distributed bent tubes 1-10 enable this embodiment to provide equal viscous resistance at all locations, thereby making it suitable for vibration reduction under external forces in all directions.

[0143] In addition, the elastic component includes a first elastic component and a second elastic component, the first elastic component being wound around the outer periphery of the inertial-capacitive damping assembly, and the second elastic component being sleeved on the outer periphery of the first elastic component.

[0144] The first elastic component is spring 1-5. In other embodiments, the first elastic component may be replaced with other elastic components, such as rubber damping pads, diaphragms, bellows, etc.

[0145] In some embodiments, the second elastic component is a rubber damping pad 1-4. Similarly, in other embodiments, the second elastic component can be replaced with other elastic components, such as a spring, diaphragm, bellows, etc.

[0146] When the building above is subjected to external forces and vibrates, the resulting disturbances include horizontal and vertical displacements, as well as rotational torque. For horizontal displacement, multiple piston dampers 1-2 connected by connecting plate 1-1 are used for energy dissipation and vibration reduction. When connecting plate 1-1 moves horizontally along with the structure above, the pistons inside the piston dampers 1-2, which are under tension or compression, move to dissipate energy, thereby reducing the horizontal displacement of the structural foundation.

[0147] Regarding the rotational torque, when the connecting plate 1-1 twists along with the upper structure, since the piston damper 1-2, the connecting plate 1-1, and the first outer shell 1-3 are all connected by ball joints, the piston damper 1-2 is subjected to torsional tension. The piston movement inside the piston damper 1-2 dissipates energy and reduces the torsional torque of the structural foundation.

[0148] For vertical displacement, when the connecting plate 1-1 moves up and down following the upper structure, the outer cylinder 1-11 moves up and down with the connecting plate 1-1, while the push rod 1-7 remains relatively stationary due to the fixation of the base plate 1-6. When the outer cylinder 1-11 moves up and down, the push rod 1-7 reciprocates relative to the inner cylinder 1-9, creating a pressure difference between the inner cylinder 1-9 and the outer cylinder 1-11. This causes the viscous damping fluid in the outer cylinder 1-11 to flow in the curved tube 1-10, amplifying inertia. When the viscous damping fluid flows through the damping mesh in the curved tube 1-10, it is further decelerated, achieving energy dissipation.

[0149] Furthermore, the inertial-capacitive multi-directional vibration damping device can reduce or even prevent external force interference from all directions of the upper structural foundation. When the vibration or disturbance of the structural foundation ends, the rubber damping pads 1-4, springs 1-5, and inertial-capacitive damping components can recover their deformation and achieve self-recovery.

[0151] The torsion connection device 2 includes a torsion spindle 2-2; The thrust anti-pull-out device 4 includes thrusts 4-3; Twisting the torsion main shaft 2-2 can drive the spike 4-3 to insert into the soil via the gear transmission device 3.

[0152] like Figure 3The diagram shows the structure of the torsion connection device 2, which includes a second housing 2-1. The first housing 1-3 and the second housing 2-1 are fixedly connected. The torsion main shaft 2-2 is disposed inside the second housing 2-1 and can rotate around its axis.

[0153] The second outer shell 2-1 is a cylindrical structure with the same outer diameter as the first outer shell 1-3, and is bolted to the first outer shell 1-3.

[0154] A torsion bar 2-3 is radially arranged on the outer periphery of the torsion main shaft 2-2. One end of the torsion bar 2-3 is connected to the torsion main shaft 2-2, and the other end of the torsion bar 2-3 is connected to the second outer shell 2-1.

[0155] Four torsion bars 2-3 are provided, and the four torsion bars 2-3 are evenly distributed around the circumference of the main torsion axis 2-2. In some embodiments, the number of torsion bars 2-3 can also be 2, 3, 5, 6, 8, etc., and preferably, all torsion bars 2-3 are evenly distributed around the circumference of the main torsion axis 2-2. In this embodiment, the four torsion bars 2-3 form a cross shape, and the main torsion axis 2-2 can be rotated by manually moving the torsion bars 2-3.

[0156] The connection between the torsion bar 2-3 and the torsion spindle 2-2 is a fixed connection, such as by welding or one-time molding. The connection between the torsion bar 2-3 and the second housing 2-1 is also a fixed connection, such as by welding. Furthermore, the axis of the torsion spindle 2-2 coincides with the axis of the second housing 2-1, and the four torsion bars 2-3 are all the same size and are all on the same horizontal plane.

[0160] There are four secondary gears 3-2, which are evenly distributed around the circumference of the main gear 3-1. The four secondary gears 3-2 are identical in size and are evenly distributed around the outer circumference of the main gear 3-1 during installation.

[0161] When the torsion spindle 2-2 rotates, it drives the main gear 3-1 to rotate. Under the constraint of the secondary gear 3-2 and the third housing 3-4, the main gear 3-1 rotates around its own axis. The torsional force of the main gear 3-1 is then transmitted to the thrust anti-pull device 4 below.

[0162] like Figure 5 As shown, the thrust anti-pull device 4 also includes a fourth housing 4-5, and an anti-pull spindle 4-1 is provided inside the fourth housing 4-5. The anti-pull spindle 4-1 is connected to the main gear 3-1, so that when the main gear 3-1 rotates, the anti-pull spindle 4-1 rotates with the main gear 3-1.

[0166] Specifically, the fourth outer shell 4-5 is provided with two layers of openings, each layer containing multiple openings. In this embodiment, each layer contains 6 openings. Of course, in other embodiments, each layer may contain 4, 8, 10, or 7 openings, etc. The actual number can be set according to the requirements. The openings are configured to provide a sliding track for the insertion of the spike 4-3 into the soil.

[0167] The number of openings in the upper and lower layers is the same, and the positions of the openings in the upper and lower layers correspond one-to-one. Each opening is equipped with a vertical rod 4-4, and the upper and lower ends of the vertical rod 4-4 are connected to the fourth outer shell 4-5. The vertical rod 4-4 passes through the hole provided in the spike 4-3, thereby defining the center position of the spike 4-3.

[0168] The outer wall of the anti-pull-out spindle 4-1 is hinged to multiple protrusions 4-3. Specifically, multiple hinges 4-2 are provided on the outer wall of the anti-pull-out spindle 4-1, and each hinge 4-2 is connected to a protrusion 4-3, so that the protrusion 4-3 can swing around the hinge 4-2.

[0170] The pile head 5 connected below the thrust anti-pull device 4 is conical, which reduces the resistance of the anti-pull pile to the soil.

The inner cylinder 1-9 is fitted inside the outer cylinder 1-11. The upper end of the push rod 1-7 is inserted into the inner cylinder 1-9 and can reciprocate within the inner cylinder 1-9. The outer cylinder 1-11, the inner cylinder 1-9, the sealing cover 1-8, and the connecting plate 1-1 form a first enclosed space, and the inner cylinder 1-9 and the upper surface of the push rod 1-7 form a second enclosed space. The first enclosed space is filled with viscous damping fluid. A bent tube 1-10 is also provided in the first enclosed space. The bent tube 1-10 has a through hole inside, and one end of the through hole is connected to the second enclosed space, and the other end of the through hole is connected to the first enclosed space.

[0180] The outer cylinder 1-11 is preferably cylindrical, and the outer cylinder 1-11 and the connecting plate 1-1 are preferably connected by welding to improve sealing performance. The inner cylinder 1-9 is preferably cylindrical, and the contact surface between the inner cylinder 1-9 and the push rod 1-7 is the sealing surface. To improve sealing performance, a sealing ring can be added to the contact surface between the inner cylinder 1-9 and the push rod 1-7.

[0181] Viscous damping fluid is an oily liquid that attenuates mechanical kinetic energy through viscous resistance, primarily used to shorten the time of mechanical oscillation or movement. This liquid is typically pale yellow and composed of various water-soluble additives; its viscosity coefficient and other technical parameters are adjusted according to the application scenario.

[0182] In this embodiment, the bent tube 1-10 is an S-shaped tube. Specifically, one end of the bent tube 1-10 is connected to the upper wall of the inner cylinder 1-9, thereby enabling the through hole to connect to the second closed space; the bent tube 1-10 extends upward from the upper wall of the inner cylinder 1-9, bends and then extends downward, and then bends and then extends upward again.

[0183] To improve viscous resistance, multiple damping meshes are installed inside the bent tube 1-10. Specifically, one, two, three, or other damping meshes can be installed inside a single bent tube 1-10. The damping meshes can be made of materials such as stainless steel or rubber, with the specific material selected based on the application scenario and requirements. The damping meshes generally employ a multi-layer structure, with an inner damping layer that effectively absorbs impact energy; an outer wear-resistant layer that prevents material wear; and a middle reinforcing layer that increases the material's strength and stability.

[0184] There are multiple bent tubes 1-10, and the multiple bent tubes 1-10 are evenly distributed along the circumference of the inner cylinder 1-9.

[0185] The uniformly distributed bent tubes 1-10 enable this embodiment to provide equal viscous resistance at all locations, thereby making it suitable for vibration reduction under external forces in all directions.

[0186] In addition, the elastic component includes a first elastic component and a second elastic component, the first elastic component being wound around the outer periphery of the inertial-capacitive damping assembly, and the second elastic component being sleeved on the outer periphery of the first elastic component.

[0187] The first elastic component is spring 1-5. In other embodiments, the first elastic component may be replaced with other elastic components, such as rubber damping pads, diaphragms, bellows, etc.

[0188] In some embodiments, the second elastic component is a rubber damping pad 1-4. Similarly, in other embodiments, the second elastic component can be replaced with other elastic components, such as a spring, diaphragm, bellows, etc.

[0189] When the building above is subjected to external forces and vibrates, the resulting disturbances include horizontal and vertical displacements, as well as rotational torque. For horizontal displacement, multiple piston dampers 1-2 connected by connecting plate 1-1 are used for energy dissipation and vibration reduction. When connecting plate 1-1 moves horizontally along with the structure above, the pistons inside the piston dampers 1-2, which are under tension or compression, move to dissipate energy, thereby reducing the horizontal displacement of the structural foundation.

[0190] Regarding the rotational torque, when the connecting plate 1-1 twists along with the upper structure, since the piston damper 1-2, the connecting plate 1-1, and the first outer shell 1-3 are all connected by ball joints, the piston damper 1-2 is subjected to torsional tension. The piston movement inside the piston damper 1-2 dissipates energy and reduces the torsional torque of the structural foundation.

[0191] For vertical displacement, when the connecting plate 1-1 moves up and down following the upper structure, the outer cylinder 1-11 moves up and down with the connecting plate 1-1, while the push rod 1-7 remains relatively stationary due to the fixation of the base plate 1-6. When the outer cylinder 1-11 moves up and down, the push rod 1-7 reciprocates relative to the inner cylinder 1-9, creating a pressure difference between the inner cylinder 1-9 and the outer cylinder 1-11. This causes the viscous damping fluid in the outer cylinder 1-11 to flow in the curved tube 1-10, amplifying inertia. When the viscous damping fluid flows through the damping mesh in the curved tube 1-10, it is further decelerated, achieving energy dissipation.

[0192] Furthermore, the inertial-capacitive multi-directional vibration damping device can reduce or even prevent external force interference from all directions of the upper structural foundation. When the vibration or disturbance of the structural foundation ends, the rubber damping pads 1-4, springs 1-5, and inertial-capacitive damping components can recover their deformation and achieve self-recovery.

[0193] The inertial capacity multi-directional vibration damping device 1 is connected to a torsion connection device 2 below it, the torsion connection device 2 is connected to a gear transmission device 3 below it, the gear transmission device 3 is connected to a spike anti-pull-out device 4 below it, and the spike anti-pull-out device 4 is connected to a pile head 5 below it.

[0194] The torsion connection device 2 includes a torsion spindle 2-2; The thrust anti-pull-out device 4 includes thrusts 4-3; Twisting the torsion main shaft 2-2 can drive the spike 4-3 to insert into the soil via the gear transmission device 3.

[0195] like Figure 3 The diagram shows the structure of the torsion connection device 2, which includes a second housing 2-1. The first housing 1-3 and the second housing 2-1 are fixedly connected. The torsion main shaft 2-2 is disposed inside the second housing 2-1 and can rotate around its axis.

[0196] The second outer shell 2-1 is a cylindrical structure with the same outer diameter as the first outer shell 1-3, and is bolted to the first outer shell 1-3.

[0197] A torsion bar 2-3 is radially arranged on the outer periphery of the torsion main shaft 2-2. One end of the torsion bar 2-3 is connected to the torsion main shaft 2-2, and the other end of the torsion bar 2-3 is connected to the second outer shell 2-1.

[0198] Four torsion bars 2-3 are provided, and the four torsion bars 2-3 are evenly distributed around the circumference of the main torsion axis 2-2. In some embodiments, the number of torsion bars 2-3 can also be 2, 3, 5, 6, 8, etc., and preferably, all torsion bars 2-3 are evenly distributed around the circumference of the main torsion axis 2-2. In this embodiment, the four torsion bars 2-3 form a cross shape, and the main torsion axis 2-2 can be rotated by manually moving the torsion bars 2-3.

[0199] The connection between the torsion bar 2-3 and the torsion spindle 2-2 is a fixed connection, such as by welding or one-time molding. The connection between the torsion bar 2-3 and the second housing 2-1 is also a fixed connection, such as by welding. Furthermore, the axis of the torsion spindle 2-2 coincides with the axis of the second housing 2-1, and the four torsion bars 2-3 are all the same size and are all on the same horizontal plane.

[0200] like Figure 4The diagram shows the structure of the gear transmission device 3, which includes a third housing 3-4, which is fixedly connected to the second housing 2-1. Specifically, the third housing 3-4 and the second housing 2-1 are connected by bolts or screws, preferably countersunk screws. If capped screws are used, a clearance groove for the nut needs to be provided on the lower surface of the first housing 1-3.

[0201] like Figure 4 As shown, the gear transmission device 3 further includes a main gear 3-1, which is disposed inside the third housing 3-4, specifically at the center of the third housing 3-4. That is, the axis of the main gear 3-1 coincides with the axis of the third housing 3-4; the inner wall of the third housing 3-4 is provided with teeth 3-3, and a secondary gear 3-2 meshes between the main gear 3-1 and the third housing 3-4; the secondary gear 3-2 meshes with the main gear 3-1 and also with the teeth 3-3 on the inner wall of the third housing 3-4.

[0202] The main gear 3-1 is connected to the torsion spindle 2-2. Specifically, the main gear 3-1 is connected to the cross joint 3-5, the lower surface of the torsion spindle 2-2 is provided with a cross joint groove, and the cross joint 3-5 is inserted into the cross joint groove on the lower surface of the torsion spindle 2-2.

[0203] There are four secondary gears 3-2, which are evenly distributed around the circumference of the main gear 3-1. The four secondary gears 3-2 are identical in size and are evenly distributed around the outer circumference of the main gear 3-1 during installation.

[0204] When the torsion spindle 2-2 rotates, it drives the main gear 3-1 to rotate. Under the constraint of the secondary gear 3-2 and the third housing 3-4, the main gear 3-1 rotates around its own axis. The torsional force of the main gear 3-1 is then transmitted to the thrust anti-pull device 4 below.

[0205] like Figure 5 As shown, the thrust anti-pull device 4 also includes a fourth housing 4-5, and an anti-pull spindle 4-1 is provided inside the fourth housing 4-5. The anti-pull spindle 4-1 is connected to the main gear 3-1, so that when the main gear 3-1 rotates, the anti-pull spindle 4-1 rotates with the main gear 3-1. The outer wall of the pull-out main shaft 4-1 is hinged with a plurality of the spikes 4-3, which penetrate the fourth outer shell 4-5 and are inserted into the soil.

[0206] The fourth outer shell 4-5 is a cylindrical structure. The outer diameter of the fourth outer shell 4-5 is the same as that of the third outer shell 3-4. The fourth outer shell 4-5 is fixedly connected to the third outer shell 3-4, preferably detachably connected, such as by bolts or screws.

[0207] The pull-out resistant spindle 4-1 is located at the center of the fourth housing 4-5, and the pull-out resistant spindle 4-1 is connected to the main gear 3-1. Specifically, a cross joint 3-5 is connected below the main gear 3-1, and a cross joint groove 4-6 is provided on the upper surface of the pull-out resistant spindle 4-1. The cross joint 3-5 below the main gear 3-1 is inserted into the cross joint groove 4-6 on the upper surface of the pull-out resistant spindle 4-1.

[0208] The fourth outer shell 4-5 is provided with multiple openings, and a vertical rod 4-4 is provided in each opening. The protrusion 4-3 is provided with a through hole, and the vertical rod 4-4 passes through the hole.

[0209] Specifically, the fourth outer shell 4-5 is provided with two layers of openings, each layer containing multiple openings. In this embodiment, each layer contains 6 openings. Of course, in other embodiments, each layer may contain 4, 8, 10, or 7 openings, etc. The actual number can be set according to the requirements. The openings are configured to provide a sliding track for the insertion of the spike 4-3 into the soil.

[0210] The number of openings in the upper and lower layers is the same, and the positions of the openings in the upper and lower layers correspond one-to-one. Each opening is equipped with a vertical rod 4-4, and the upper and lower ends of the vertical rod 4-4 are connected to the fourth outer shell 4-5. The vertical rod 4-4 passes through the hole provided in the spike 4-3, thereby defining the center position of the spike 4-3.

[0211] The outer wall of the anti-pull-out spindle 4-1 is hinged to multiple protrusions 4-3. Specifically, multiple hinges 4-2 are provided on the outer wall of the anti-pull-out spindle 4-1, and each hinge 4-2 is connected to a protrusion 4-3, so that the protrusion 4-3 can swing around the hinge 4-2.

[0212] One side of the spike 4-3 is an outwardly convex arc shape, and the other side is an inwardly concave arc shape. The holes on the spike 4-3 match the shape of the spike 4-3, that is, one side is an outwardly convex arc shape, and the other side is an inwardly concave arc shape.

[0213] The pile head 5 connected below the thrust anti-pull device 4 is conical, which reduces the resistance of the anti-pull pile to the soil.

[0214] Example 4 This embodiment provides an installation method for prefabricated vibration-damping and tension-resistant piles based on inertial-capacitive damping, used for installing the aforementioned prefabricated vibration-damping and tension-resistant piles. The installation method includes: S1. Connect the torsion connection device 2, gear transmission device 3, spike anti-pull device 4 and pile head 5 according to the design requirements to form the pile body. When forming the pile body, the second outer shell 2-1 and the third outer shell 3-4 are not connected. The torsion connection device 2 and the gear transmission device 3 are connected only by the torsion main shaft 2-2 and the main gear 3-1 so that when the torsion main shaft 2-2 is rotated, the second outer shell 2-1 is fixed and cannot be rotated.

[0215] Furthermore, before installing the pile body, the number of gear transmission devices 3 and anti-pull-out devices 4 to be used are determined according to the design length, burial depth and soil layer thickness of the pile foundation, and the pile body is formed according to the design requirements.

[0216] S2. Insert the pile into the soil; specifically, the pile can be inserted into the soil using the hammering method, vibration method, or pile driving method.

[0217] S3. Rotate the torsion main shaft 2-2 to insert the protrusion 4-3 into the soil; The torsion bar 2-3 rotates, thereby driving the torsion main shaft 2-2 to rotate. The rotation of the torsion main shaft 2-2 drives the main gear 3-1 of the gear transmission device 3 to drive. Under the constraint of the secondary gear 3-2 and the third housing 3-4 with teeth 3-3, the main gear 3-1 realizes its own rotation around the axis. The main gear 3-1 can transmit the torsional torque to the spike anti-pull device 4 through the cross joint 3-5.

[0218] The pull-out resisting spindle 4-1 of the spike resisting device 4 rotates around its axis under the drive of the main gear 3-1. A hinge 4-2 located outside the pull-out resisting spindle 4-1 causes the root of the spike 4-3 to twist. A pre-drilled hole in the center of the spike 4-3 penetrates the vertical rod 4-4, which is connected to the fourth outer shell 4-5. This allows the spike 4-3 to expand outwards, thus inserting itself into the soil and achieving foundation reinforcement and pull-out resistance.

[0219] After the spike 4-3 is inserted into the soil, the second outer shell 2-1 and the third outer shell 3-4 are fixedly connected according to the design requirements.

[0220] S4. Connect the inertial-capacitance multi-directional vibration damping device 1 to the torsional connection device 2. Install the upper structural foundation using the installed anti-uplift piles.

[0221] The inertial-capacitance multi-directional vibration damping device 1 is bolted to the torsion connection device on the upper part of the completed pile body, thus connecting it to the pile body. The upper connecting plate of the inertial-capacitance multi-directional vibration damping device 1 has pre-drilled bolt holes for connection to the superstructure. When the superstructure experiences vibration or external disturbance, the piston damper 1-2, connected by a ball joint around the connecting plate 1-1, reduces the horizontal displacement of the foundation. The vertical displacement of the connecting plate 1-1 is constrained by the rubber damping pad 1-4, the spring 1-5, and the inertial-capacitance damping assembly. The compression or tension of the inertial-capacitance damping assembly causes the push rod 1-7 to move relative to the inner cylinder 1-9, creating a pressure difference between the inner cylinder 1-9 and the outer cylinder 1-11. This causes the viscous damping fluid in the outer cylinder 1-11 to flow in the bent tube 1-10, amplifying inertia.

[0222] When the viscous damping fluid flows through the damping mesh inside the curved tube 1-10, it decelerates and dissipates energy. When the structural vibration or disturbance ends, the rubber damping pad 1-4, spring 1-5, and inertial capacitive damping assembly can recover their deformation, achieving a self-recovery function.

[0223] The above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
