Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, specifically to a pile-slab retaining wall with inter-pile anti-settlement structure. Background Technology

[0002] The piles are the vertical support structure of a pile-slab retaining wall, usually reinforced concrete piles arranged at certain intervals. The piles penetrate deep into the ground and rely on the friction between the pile body and the surrounding soil and the bearing capacity of the pile ends to provide stable support and prevent soil sliding and collapse. The retaining wall panels are installed between the piles to directly block the soil and bear the lateral pressure of the soil. These retaining wall panels can be precast reinforced concrete slabs, steel plates, etc., and the appropriate materials and forms are selected according to the project requirements and actual conditions. In addition to the piles and retaining wall panels, there may also be some auxiliary components, such as connectors that connect the piles and retaining walls, and support structures to enhance the overall stability. The pile-slab retaining wall between two piles is the retaining wall. As a commonly used support structure, the retaining wall plays a vital supporting role for the slope soil.

[0003] When pile-slab retaining walls are used to retain soil on slopes, the geological conditions in the area where the retaining wall is located are complex and variable, and there may be uneven settlement of the foundation. Once the foundation settles, the retaining wall between the two piles is easily affected, which can lead to settlement, cracking and other problems. This will not only weaken the retaining effect of the retaining wall and increase the risk of slope collapse, threatening the safety of engineering facilities and the surrounding environment, but also significantly increase the later maintenance costs.

[0004] Utility model CN222294942U discloses a novel pile-slab retaining wall for preventing unstable settlement of the retaining plate. It includes multiple piles and an irregularly shaped ground beam fixed between adjacent piles. A retaining plate is placed on top of the irregularly shaped ground beam, and multiple symmetrically arranged positioning rods are fixed to the top of the beam. The retaining plate is positioned between the positioning rods, and a pressure ring is rotatably sleeved on the upper outer end of each positioning rod. An operating groove is formed on the outer wall of the pressure ring, and a positioning and squeezing mechanism for limiting the position of the pressure ring is provided within the operating groove. The piles, irregularly shaped ground beam, and retaining plate provided by this utility model, by setting a ground beam between adjacent piles, provide a stable and rigid support platform for the retaining plate, preventing uneven settlement of the retaining plate during installation. Utility Model Content

[0005] This utility model provides a pile-slab retaining wall with inter-pile anti-settlement structure, the purpose of which is to ensure the stability and durability of the anti-settlement structure while allowing small displacement of the wall panel modules.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A pile-slab retaining wall anti-settlement structure includes: several wall panel modules arranged at equal intervals, the wall panel modules being installed on vertical piles symmetrically arranged at both ends, the bottoms of the symmetrically arranged vertical piles being respectively installed on corresponding bases, and elastic pads being provided between two adjacent wall panel modules.

[0008] Furthermore, the bottom of the assembly formed by several wall panel modules is provided with a bottom support plate, which is set on the top of the base; the top of the assembly formed by several wall panel modules is provided with a top pressure plate, and both ends of the bottom support plate and both ends of the top pressure plate are installed on vertical piles.

[0009] Furthermore, the bottom support plate and the top pressure plate are connected by multiple vertical threaded rods, each with a bottom support block at its bottom and a nut at its top.

[0010] Furthermore, a bottom groove is provided at the bottom of the bottom support plate, and the bottom support block is installed in the bottom groove.

[0011] Furthermore, symmetrical installation slots are opened on both sides of the vertical pile, and the two ends of the bottom support plate, the two ends of several wall panel modules, and the two ends of the top pressure plate are all installed in the corresponding installation slots.

[0012] Furthermore, the cross-section of the elastic pad is cross-shaped, and the two sides of the wall panel module are symmetrically provided with insertion grooves, which are adapted to the protrusions on the side of the elastic pad.

[0013] Furthermore, the mounting slot is provided with a filling cavity, which is filled with a filling layer.

[0014] This utility model has the following beneficial effects:

[0015] This utility model uses the base of the pile to provide stable support for the bottom support plate. The two ends of the bottom support plate extend into the installation slots of the vertical pile. The base provides stable support, reducing the risk of settlement of the bottom support plate. The bottom support plate supports the wall panel module, thereby reducing the risk of settlement of the wall panel module. In turn, it reduces the risk of settlement of the retaining wall composed of the bottom support plate, wall panel module, pad block, top pressure plate and fixing components, ensuring safety and reducing later maintenance costs.

[0016] By filling the filling cavity with filler to accommodate the small displacement and deformation space between the wall panel module and the pile body, the risk of damage or deformation cracking of the wall panel module caused by external force is reduced. The setting of the pad block allows for small displacement and deformation space between two adjacent wall panel modules, further reducing the risk of damage or deformation cracking of the wall panel module caused by external force.

[0017] The retaining wall is assembled by combining bottom support plates, wall panel modules, pad blocks, top pressure plates, and fixing components to form a stable retaining wall structure. Furthermore, the modular design allows for separate transport, reducing volume and making transportation more convenient. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] In this utility model, the terms "longitudinal," "lateral," "vertical," "upper," "lower," "front," "rear," "left," "right," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0030] Please refer to Figure 1-2 In the practical application of the pile-slab retaining wall anti-settlement structure, it is necessary to construct and install it according to the following specific implementation methods to ensure that the structure can fully exert its anti-settlement function and has good stability and durability.

[0031] Reference Figure 1-4 The present invention relates to a pile-plate retaining wall anti-settlement structure between piles, comprising: a plurality of wall plate modules 3 arranged at equal intervals, the plurality of wall plate modules 3 being installed on vertical piles 102 symmetrically arranged at both ends (both ends being the width side in this embodiment), the bottoms of the symmetrically arranged vertical piles 102 being respectively installed on corresponding bases 101, and elastic pads 4 being provided between two adjacent wall plate modules 3.

[0032] When installing the base 101, professional measuring instruments, such as levels and theodolites, can be used to accurately measure and adjust the levelness and position of the base 101. The base 101 is typically made of high-strength concrete to ensure sufficient load-bearing capacity. After the base 101 is installed, the vertical piles 102 are installed. The vertical piles 102 are the main load-bearing components of the entire pile-slab retaining wall structure. The vertical piles 102 are made of reinforced concrete or steel pipe piles, with the appropriate pile type and specifications selected according to design requirements. The wall panel modules 3 are the main retaining components of the pile-slab retaining wall; their number is determined according to design requirements, and they are equidistantly spaced vertically. The wall panel modules 3 are typically made of reinforced concrete slabs or steel plates, possessing good strength and durability. When installing the wall panel modules 3, it is essential to ensure that elastic pads 4 are placed between adjacent wall panel modules 3.

[0033] Reference Figure 5-6 To enhance the installation stability of the wall panel module 3, a bottom support plate 2 is set at the bottom of the entire wall panel module 3, and the bottom support plate 2 is set at the top of the base 101; a top pressure plate 5 is set at the top of the entire wall panel module 3, and both ends of the bottom support plate 2 and the top pressure plate 5 are installed on the vertical piles 102.

[0034] The bottom support plate 2 is installed on top of the base 101, and its function is to provide bottom support for the wall panel module 3. The bottom support plate 2 is typically made of steel or high-strength concrete, possessing good load-bearing capacity and stability. When installing the bottom support plate 2, it must be accurately placed on top of the base 101. The bottom support plate 2 can be fixedly connected to the vertical stake 102 using bolts to ensure its secure installation. The top pressure plate 5 is installed at the very top of several wall panel modules 3, and its function is to provide top restraint for the wall panel modules 3, preventing upward displacement. The top pressure plate 5 is typically made of the same material as the bottom support plate 2, using steel or high-strength concrete. When installing the top pressure plate 5, it must be accurately placed on top of the wall panel module 3. The top pressure plate 5 can be fixedly connected to the vertical stake 102 using bolts or welding to ensure its secure installation.

[0035] In order to provide installation space for the bottom support block 601, a bottom groove 201 is opened at the bottom of the bottom support plate 2, and the bottom support block 601 is installed in the bottom groove 201.

[0036] In a specific embodiment, the wall panel module 3 and the elastic pad 4 can be connected by integral molding, bolt connection or mortise and tenon connection. In order to increase the ease of installation and stability of the wall panel module 3 and the elastic pad 4, this embodiment adopts the mortise and tenon connection. The cross-section of the elastic pad 4 is cross-shaped. The upper and lower sides of the wall panel module 3 are symmetrically provided with insertion grooves 301, which are adapted to the protrusions on the side of the elastic pad 4.

[0037] When installing the elastic pad 4, its protruding part must be accurately inserted into the insertion groove 301 of the wall panel module 3 to ensure the installation stability of the elastic pad 4. The elastic pad 4 is made of high-strength rubber material, such as nitrile rubber or neoprene rubber. When the pile-slab retaining wall anti-settlement structure is in operation, soil pressure and other external forces will be transmitted to the wall panel module 3 and the elastic pad 4. The high-strength rubber can stably support the wall panel module 3 while maintaining elastic deformation. It avoids excessive deformation or failure of the wall panel module 3 while allowing small displacement of the wall panel module 3, thus ensuring the stability and durability of the anti-settlement structure.

[0038] The bottom support plate 2, several wall panel modules 3, and top pressure plate 5 can be installed on the vertical pile 102 in various ways, such as direct bolt connection, mounting plate + bolt connection, and groove snap-fit ​​connection. In this embodiment, the groove snap-fit ​​connection method is preferred. Installation slots 103 are symmetrically opened on both sides of the vertical pile 102, and both ends of the bottom support plate 2, several wall panel modules 3, and top pressure plate 5 are installed in the corresponding installation slots 103. The size and shape of the installation slots 103 should be designed according to the size and shape of both sides of the bottom support plate 2, wall panel modules 3, and top pressure plate 5 to ensure that they can be accurately installed in the installation slots 103.

[0039] Reference Figure 2 and Figure 8 To further increase installation stability, the bottom support plate 2 and the top pressure plate 5 are connected and fixed by multiple vertical threaded rods 602. Each vertical threaded rod 602 has a bottom support block 601 at its bottom and the top of each vertical threaded rod 602 is fixed by a nut 603.

[0040] After the bottom support plate 2, wall panel module 3, and top pressure plate 5 are installed, the vertical threaded rod 602 is installed. Several sets of through holes 9 are longitudinally drilled through the bottom support plate 2, wall panel module 3, elastic pad 4, and top pressure plate 5 for the vertical threaded rod 602 to pass through. The diameter of the bottom groove 201 is larger than the diameter of the through holes 9. When installing the vertical threaded rod 602, it must be passed sequentially through the through holes 9 on the bottom support plate 2, wall panel module 3, elastic pad 4, and top pressure plate 5. A bottom support block 601 is provided at the bottom of the vertical threaded rod 602, and the bottom support block 601 is installed in the bottom groove 201. The function of the bottom support block 601 is to provide bottom support for the vertical threaded rod 602 and prevent it from sinking. When installing the bottom support block 601, it must be accurately placed in the bottom groove 201 and ensured to be firmly connected to the vertical threaded rod 602.

[0041] The top of the vertical threaded rod 602 is secured by a nut 603. The nut 603 is located on the upper part of the top pressure plate 5. Tightening the nut 603 creates a preload force on the bottom support plate 2, wall panel module 3, and top pressure plate 5 by the vertical threaded rod 602, thereby enhancing the overall integrity and stability of the structure. Simultaneously, the tightening torque of the nut 603 must be controlled to avoid damage to the vertical threaded rod 602 or other components due to excessive tightening torque.

[0042] To prevent moisture and debris from entering the mounting slot 103 and affecting the stability and durability of the structure, the filling cavity 8 inside the mounting slot 103 is treated after the vertical threaded rod 602 is installed. The mounting slot 103 has a filling cavity 8, which is filled with a filling layer 7. The filling layer 7 typically uses polyurethane foam sealant, silicone sealant, or butyl rubber sealant. Polyurethane foam sealant, after foaming, can fill gaps of various shapes and has good adhesion to the surface of objects, forming an effective seal. Simultaneously, polyurethane foam has a certain degree of elasticity, capable of withstanding a certain degree of compression and vibration, acting as a buffer to accommodate minor displacements and deformations that may occur between piles. Silicone sealant has excellent sealing performance, effectively preventing the penetration of media such as water and air. Furthermore, silicone material itself has good elasticity and flexibility, capable of absorbing a certain amount of impact force, acting as a buffer and reducing damage to the pile slab or structural deformation caused by external forces. Butyl rubber sealant has extremely low air and water permeability, excellent sealing performance, and good elasticity and resistance to compression deformation, providing reliable buffering and maintaining good performance even under long-term pressure.

[0043] The working principle of the pile-slab retaining wall anti-settlement structure provided by this utility model is as follows:

[0044] When constructing a retaining wall, a thorough site survey must first be conducted. Based on design requirements and geological conditions, the precise location of the piles on one side of the slope protection is determined. Then, pile construction begins. First, a pit of appropriate depth and size is excavated underground. The bottom of the pit is filled with a certain thickness of gravel, 30-50 cm thick. The gravel is then compacted using compaction equipment to achieve the design standard, thereby enhancing the bearing capacity of the foundation and providing a stable foundation for subsequent pile construction. Next, the reinforcing cage for pouring the pile body is tied and the matching steel reinforcement is installed. The formwork is used for pouring the concrete for the pile body 1. After the pile body 1 is formed, the formwork is removed. The corresponding number of pile bodies 1 are poured according to the length of the slope support. A retaining wall structure consisting of a bottom support plate 2, a wall panel module 3, a pad block 4, a top pressure plate 5, and a fixing component 6 is placed between two adjacent pile bodies 1. The nut 603 in the fixing component 6 is removed. Then the bottom support plate 2 is put on the vertical threaded rod 602 until the bottom support block 601 enters the bottom groove 201 at the bottom of the bottom support plate 2. Then the bottom support plate 2 is placed on the two The base 101 supports the bottom support plate 2, effectively reducing the risk of settlement. Both ends of the bottom support plate 2 extend into the mounting slots 103 on the vertical posts 102 on both sides. The bottom support plate 2 and the mounting slots 103 maintain a space filled with a cavity 8. Multiple sets of wall panel modules 3 and spacers 4 are then placed from bottom to top in the order of wall panel module 3, spacer 4, and wall panel module 3 again. The upper part of the spacer 4 is inserted into the insertion groove 301 of the wall panel module 3 above it, and the lower part of the spacer 4 is inserted into... Insert the upper wall panel module 3 into the insertion groove 301 below it. Use the spacer 4 to separate the upper and lower wall panel modules 3 until the uppermost wall panel module 3 is installed. Then, thread the nut 603 onto the corresponding vertical threaded rod 602 and tighten the nut 603 so that the bottom support block 601 abuts against the bottom support plate 2, and the nut 603 abuts against the top pressure plate 5. This keeps the spacer 4 and the wall panel module 3 pressed together. The bottom support plate 2, wall panel module 3, spacer 4, top pressure plate 5, and fixing component 6 work together to form a complete retaining wall (e.g., Figure 9 (As shown), and fill the soil and one side of the retaining wall with the soil to block the slope soil.

[0045] Through the above specific implementation methods, it can be ensured that the pile-slab retaining wall's inter-pile anti-settlement structure can be installed and constructed according to design requirements, fully utilizing its anti-settlement function, guaranteeing the structure's stability and durability, and providing a reliable guarantee for the safe operation of the project. In practical applications, it is also necessary to make appropriate adjustments and optimizations to the above implementation methods according to specific project conditions and design requirements to meet the needs of different projects.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
