Technical Field
[0001] This utility model relates to the field of foundation settlement compensation technology, and in particular to a foundation settlement compensation device. Background Technology
[0002] Foundation settlement compensation devices are crucial facilities for ensuring the safety and stability of buildings. When foundation settlement occurs, they can precisely adjust and compensate for the differences in settlement, avoiding structural damage and cracking caused by uneven foundation settlement. They also play a key role in the research and engineering control of settlement deformation mechanisms in composite foundations. In-depth analysis of their working principles and practical application effects helps researchers reveal the inherent laws of settlement deformation in composite foundations, providing a scientific theoretical basis and effective control strategies for engineering practice, thereby further optimizing foundation treatment schemes and improving the quality of engineering construction.
[0003] Patent document CN221612083U discloses a foundation settlement deformation measuring device. This solution primarily addresses the issue that existing devices cannot adjust the levelness of the device by fine-tuning the height of each support leg, leading to reduced measurement accuracy. However, it fails to consider the problem that existing foundations are difficult to automatically adjust for leveling after settlement, which can easily cause building tilting and structural damage. Furthermore, existing foundations have insufficient bearing capacity and cannot withstand the weight of large buildings, making them prone to foundation collapse. Utility Model Content
[0004] The purpose of this utility model is to provide a foundation settlement compensation device to solve the problems mentioned in the background art, such as the difficulty in automatically adjusting the level after the existing foundation settles, which easily leads to building tilting and structural damage, insufficient bearing capacity of the existing foundation, inability to support the weight of large buildings, and easy foundation collapse.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A foundation settlement compensation device includes a foundation body, a shock-absorbing pad at the bottom of the foundation body, a fixed base at the bottom of the shock-absorbing pad, and a settlement adjustment component at the bottom of the fixed base. The settlement adjustment component is used to adjust the horizontal state of the foundation body when the foundation settles. The settlement adjustment component includes liquid storage tanks evenly arranged at the bottom of the fixed base, and a connecting pipe is connected to the surfaces of two liquid storage tanks that are close to each other. Hydraulic oil is injected into the liquid storage tanks, and the hydraulic oil flows between adjacent liquid storage tanks through the connecting pipe.
[0007] Preferably, the shock-absorbing pad adopts a composite structure of rubber and metal mesh.
[0008] Preferably, the bottom of the liquid storage tank is provided with a leak-proof drainage component, which is used to prevent hydraulic oil leakage and drain excess liquid.
[0009] Preferably, the leak-proof drainage assembly includes a leak-proof layer disposed at the bottom of the storage tank, a liquid-permeable layer connected to the bottom of the leak-proof layer, a drainage layer connected to the bottom of the liquid-permeable layer, and a buffer layer connected to the bottom of the drainage layer.
[0010] Preferably, the impermeable layer is made of high-density polyethylene, the liquid permeable layer is made of crushed stone with uniform particle size, the drainage layer has interconnected drainage channels, and the buffer layer is made of elastic rubber.
[0011] Preferably, the bottom of the liquid storage tank is provided with a composite reinforcement component, which is used to enhance the overall bearing capacity of the foundation.
[0012] Preferably, the composite reinforcement component includes an I-shaped steel frame and a mounting base disposed at the bottom of the buffer layer, with the mounting base located outside the I-shaped steel frame. The I-shaped steel frames are welded together to form a grid, and support piles are installed through the grid nodes of the I-shaped steel frames. The bottom of the support piles is formed into a trumpet-shaped expansion structure by hydraulic expansion tubes.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model sets up a shock-absorbing pad and a settlement adjustment component at the bottom of the foundation. The liquid storage tank in the settlement adjustment component is connected by a connecting pipe and filled with hydraulic oil. When the foundation settles at a certain point, the liquid storage tank corresponding to the settlement area drops in force. Under the connection of the connecting pipe, the hydraulic oil in the tank flows rapidly to the settlement area. The gravity of the liquid fills the settlement gap, realizing the automatic leveling of the foundation. The shock-absorbing pad adopts a composite structure of rubber and metal mesh, which can not only buffer the external impact force, but also provide stable support for the flow of hydraulic oil and prevent the foundation from shaking excessively. Compared with the existing passive way of dealing with foundation settlement, this utility model realizes the active adjustment of foundation settlement, which greatly improves the stability and self-adjustment capability of the foundation.
[0015] 2. This utility model incorporates a composite reinforcement component and a leak-proof drainage component at the bottom of the storage tank. The composite reinforcement component consists of an I-beam steel frame welded together to form a grid, and support piles with enlarged bottom diameters that penetrate the grid nodes. The I-beam steel frame, with its unique cross-sectional shape and mechanical properties, can distribute the load borne by the foundation in multiple directions, forming a stable support frame. The bottom of the support piles is hydraulically expanded to form a trumpet-shaped diameter structure, increasing the contact area with the soil and effectively improving the foundation's tensile and compressive strength. Simultaneously, the leak-proof drainage component at the bottom of the storage tank further ensures the stability of the foundation environment, preventing liquid leakage or accumulation from affecting the foundation's bearing capacity. Compared with traditional foundation reinforcement technologies, this utility model significantly enhances the overall bearing capacity of the foundation and improves the foundation's support strength and durability for buildings.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5This embodiment provides a foundation settlement compensation device, including a foundation body 1, a shock-absorbing pad 2 at the bottom of the foundation body 1, a fixed seat 3 at the bottom of the shock-absorbing pad 2, and a settlement adjustment component at the bottom of the fixed seat 3. The settlement adjustment component is used to adjust the horizontal state of the foundation body 1 when the foundation settles. The settlement adjustment component includes liquid storage tanks 4 evenly arranged at the bottom of the fixed seat 3, and a connecting pipe 5 connecting the surfaces of two liquid storage tanks 4 that are close to each other. Hydraulic oil is injected into the inside of the liquid storage tanks 4, and the hydraulic oil flows between adjacent liquid storage tanks 4 through the connecting pipe 5. The shock-absorbing pad 2 adopts a composite structure of rubber and metal mesh.
[0024] The foundation body 1, as the core load-bearing part of the entire device, directly bears the weight of the superstructure and transmits the load downwards. The shock-absorbing pad 2 is located at the bottom of the foundation body 1 and adopts a composite structure of rubber and metal mesh. The rubber material has good elasticity and can effectively buffer the vibration transmitted from the outside and reduce the impact of vibration on the foundation body 1. The metal mesh enhances the overall strength and durability of the shock-absorbing pad 2 and prevents the rubber from deforming or being damaged under long-term stress. The shock-absorbing pad 2 can reduce the stress generated by vibration in the building and protect the foundation body 1 and the building structure.
[0025] The fixing seat 3 is located at the bottom of the shock-absorbing pad 2 and serves to connect the shock-absorbing pad 2 and the settlement adjustment component. It provides a stable installation base for the settlement adjustment component, ensuring that the components maintain a stable relative position during operation, so that the entire device can work together.
[0026] The settlement adjustment component consists of a liquid storage tank 4 evenly distributed at the bottom of the fixed base 3 and a connecting pipe 5 connecting the liquid storage tank 4. Hydraulic oil is injected into the liquid storage tank 4. When the foundation settles at a certain point, the pressure on the liquid storage tank 4 in that area decreases. Under the action of the connecting pipe 5, the hydraulic oil flows to the liquid storage tank 4 in the settlement area. The settlement gap is filled by the gravity of the hydraulic oil, and the horizontal state of the foundation body 1 is automatically adjusted to achieve dynamic compensation for foundation settlement.
[0027] The bottom of the storage tank 4 is equipped with a leak-proof drainage assembly to prevent hydraulic oil leakage and drain excess liquid. The leak-proof drainage assembly includes a leak-proof layer 6 at the bottom of the storage tank 4, a permeable layer 7 connected to the bottom of the leak-proof layer 6, a drainage layer 8 connected to the bottom of the permeable layer 7, and a buffer layer 9 connected to the bottom of the drainage layer 8. The leak-proof layer 6 is made of high-density polyethylene, the permeable layer 7 is composed of uniformly sized crushed stone, the drainage layer 8 has interconnected drainage channels, and the buffer layer 9 is made of elastic rubber.
[0028] The anti-leakage drainage assembly includes an anti-leakage layer 6, a permeable layer 7, a drainage layer 8, and a buffer layer 9. The anti-leakage layer 6 is made of high-density polyethylene material, which has excellent anti-leakage performance and can effectively prevent hydraulic oil in the storage tank 4 from leaking into the foundation soil, avoiding soil pollution and affecting foundation stability. The permeable layer 7 is made of uniformly sized crushed stone, which allows excess liquid in the foundation soil to pass through, but blocks soil particles from entering the drainage layer 8. The drainage layer 8 has interconnected drainage channels inside, which can quickly collect and drain the liquid that seeps from the permeable layer 7, keeping the foundation soil dry. The buffer layer 9 is made of elastic rubber material, which can buffer the pressure on the drainage layer 8 and further enhance the shock absorption performance of the device.
[0029] A composite reinforcement component is installed at the bottom of the liquid storage tank 4 to enhance the overall bearing capacity of the foundation body 1. The composite reinforcement component includes an I-shaped steel frame 10 and a mounting base 12 installed at the bottom of the buffer layer 9, with the mounting base 12 located outside the I-shaped steel frame 10. The I-shaped steel frames 10 are welded together to form a grid, and support piles 11 are installed through the grid nodes of the I-shaped steel frame 10. The bottom of the support piles 11 is formed into a trumpet-shaped expansion structure by hydraulic expansion tubes.
[0030] The composite reinforcement component consists of an I-beam steel frame 10 at the bottom of the buffer layer 9, support piles 11, and mounting base 12. The I-beam steel frames 10 are welded together to form a grid, which has good load-bearing capacity in both horizontal and vertical directions and can effectively disperse the load transmitted by the main foundation 1. The mounting base 12 is located outside the I-beam steel frame 10 and plays a dual role of fixing and supporting. It provides stable boundary constraints for the I-beam steel frame 10, ensuring that the grid structure remains stable under load, while transferring part of the load directly to the depth of the foundation, enhancing the connection strength between the foundation and the superstructure. The support piles 11 penetrate the grid nodes of the I-beam steel frame 10, and the bottom is formed into a trumpet-shaped expansion structure through hydraulic expansion tubes, which increases the contact area with the foundation soil, significantly improves the tensile and compressive strength of the foundation, enhances the overall load-bearing capacity of the main foundation 1, and ensures that the building remains stable even under complex geological conditions.
[0031] Working principle: When the weight of the superstructure acts on the foundation body 1, the foundation body 1 first bears the load and transmits it downwards. During the load transmission process, the shock-absorbing pad 2 plays a role. Its rubber and metal mesh composite structure absorbs external vibrations, reducing the impact of vibrations on the foundation body 1 and ensuring its stable operation. If the foundation settles, the settlement adjustment component starts to operate. Due to the settlement at a certain point, the pressure on the corresponding liquid storage tank 4 decreases. The hydraulic oil injected in the liquid storage tank 4 flows to the liquid storage tank 4 in the settlement area under the connection of the connecting pipe 5. The gravity of the hydraulic oil fills the settlement gap, thereby automatically adjusting the horizontal state of the foundation body 1 and compensating for the foundation settlement. Throughout the operation, the anti-leakage drainage components continuously ensure system stability. The anti-leakage layer 6 prevents hydraulic oil in the storage tank 4 from leaking into the foundation soil. When there is excess liquid in the foundation soil, the liquid enters the drainage layer 8 through the permeable layer 7. The interconnected drainage channels in the drainage layer 8 quickly drain the liquid, keeping the foundation soil dry. The buffer layer 9 acts as a pressure buffer and further reduces vibration in the drainage layer 8. At the same time, the composite reinforcement components provide strong support for the foundation. The grid structure composed of I-beam steel frames 10 effectively disperses the load transmitted by the main foundation 1. The mounting base 12 provides stable boundary constraints for the I-beam steel frames 10, ensuring that the grid structure remains stable under load. At the same time, it directly transmits some of the load to the depths of the foundation, enhancing the connection strength between the foundation and the superstructure. The support piles 11 penetrate the grid nodes, and their bottom flared diameter expansion structure increases the contact area with the foundation soil, improving the foundation's tensile and compressive strength. This ensures that the main foundation 1 can maintain its overall load-bearing capacity under complex working conditions, guaranteeing the safety and stability of the building.
