Description
Technical Field
[0001] This utility model relates to the field of retaining wall technology, specifically to a prefabricated retaining wall structure. Background Technology
[0002] In the field of civil engineering, retaining walls, as an important retaining structure, are widely used in highway, railway, water conservancy, and building projects. Their main function is to support roadbed fill or hillside soil, prevent deformation and instability of the fill or soil, and ensure the safety and stability of the project. Prefabricated retaining walls, with their significant advantages such as convenient construction, short construction period, and controllable quality, are gradually becoming an important direction in the development of retaining wall structures. Most prefabricated retaining walls on the market have a closed retaining surface. While this structure ensures the integrity and stability of the retaining wall to a certain extent, it has significant shortcomings in drainage design. Although some retaining walls have a few drainage holes at the bottom, rainwater can quickly seep into the backfill soil when it rains. Because the drainage holes are at the bottom, the water in the backfill soil cannot be drained quickly, and a large amount of water accumulates in the soil, which can easily lead to serious problems such as deformation, cracking, or even instability of the retaining wall. In order to solve the above problems, the inventor proposes a prefabricated retaining wall structure. Utility Model Content
[0003] To address the problem that retaining walls have a few drainage holes at the bottom, but when it rains, rainwater quickly seeps into the backfill soil, and because the drainage holes are at the bottom, the water in the backfill soil cannot be drained quickly; the purpose of this utility model is to provide a prefabricated retaining wall structure.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a prefabricated retaining wall structure, including a wall panel and a protective body. A hidden groove is provided at the center of the top of the wall panel, and the hidden groove is adapted to the protective body. Several evenly distributed lifting rings are fixedly connected to the bottom of the hidden groove. Two sets of evenly distributed inclined grooves are symmetrically provided at the top of the wall panel near the hidden groove. An installation groove is provided at the center of the back end of the wall panel. Several evenly distributed drainage holes are provided inside the wall panel near the installation groove. A filter chamber is provided inside the installation groove, and sand and gravel are provided inside the filter chamber.
[0005] Preferably, a placement groove is provided at the top of the wall panel and above the mounting groove, and a plurality of evenly distributed water-permeable holes are provided at the back end of the wall panel near the placement groove.
[0006] Preferably, a number of evenly distributed circular holes are provided between the placement groove and the installation groove, and a number of inclined blocks adapted to the inclined groove are symmetrically fixedly connected to both ends of the protective body.
[0007] Preferably, the protective body has symmetrically fixed transport ears at the top near the center, and a filter screen is provided at the end of the drain hole away from the mounting groove.
[0008] Preferably, the end of the filter chamber furthest from the filter screen is provided with geotextile.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up geotextile and filter chamber in this utility model, soil can be prevented from flowing into the drainage hole and causing blockage. The soil is then discharged outward through multiple drainage holes, thereby reducing the soil moisture content and preventing the soil from increasing lateral pressure due to water accumulation, thus improving the overall stability of the retaining wall structure. 2. By setting multiple lifting rings and inclined grooves in this utility model, it is easy to adjust the magnitude of the force on each lifting strap, thereby achieving uniform force distribution at multiple points and avoiding stress damage during the lifting process.

[0017] 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.
[0018] Example: Figure 1-5 As shown, this utility model provides a technical solution: a prefabricated retaining wall structure, including a wall panel 1 and a protective body 2. A hidden groove 22 is provided at the center of the top of the wall panel 1, and the hidden groove 22 is adapted to the protective body 2. Several evenly distributed lifting rings 24 are fixedly connected to the bottom of the hidden groove 22. Two sets of evenly distributed inclined grooves 23 are symmetrically provided at the top of the wall panel 1 near the hidden groove 22. An installation groove 3 is provided at the center of the back end of the wall panel 1. Several evenly distributed drainage holes 36 are provided inside the wall panel 1 near the installation groove 3. A filter chamber 31 is provided inside the installation groove 3, and the filter chamber 31 is filled with sand and gravel. Inclined teeth are provided on both sides of the wall panel 1 to facilitate the splicing of multiple wall panels 1. The inclined grooves 23 and the lifting rings 24 are on the same horizontal plane, facilitating... The rope passes through the inclined groove 23 and is inserted into the lifting ring 24 to complete the hoisting work. The drainage hole 36 is inclined and the other end passes through the wall panel 1 to facilitate rapid drainage. The protective body 2 is set to protect it when the lifting ring 24 is not in use, and to ensure the flatness of the top of the wall panel 1. Several lifting rings 24 are used to ensure that the wall panel 1 is subjected to balanced force during hoisting. The drainage hole 36 is used to drain the water accumulated in the soil behind the wall panel 1, reduce the soil moisture content, and prevent the soil from increasing the lateral pressure due to water accumulation, thereby improving the overall stability of the retaining wall structure. The sand and gravel in the filter chamber 31 form a filter layer, which can filter the water entering the drainage hole 36, intercept the mud, impurities and other substances in the water, prevent the drainage hole 36 from being blocked, and ensure the smooth drainage of the drainage hole 36.
[0019] A placement groove 33 is provided at the top of the wall panel 1 and above the mounting groove 3.
[0020] By adopting the above technical solution, the placement groove 33 set at the top of the wall panel 1 is to facilitate the planting of soil-stabilizing plants (such as ivy), so that the plant roots can reinforce the backfill soil and beautify the environment.
[0021] Several evenly distributed water-permeable holes 34 are provided on the back end of the wall panel 1 near the placement groove 33.
[0022] By adopting the above technical solution, a water-permeable hole 34 is provided on the back end of the wall panel 1 to facilitate the flow of some water into the placement trough 33, so as to help the plants grow.
[0023] Several evenly distributed circular holes 35 are provided between the placement groove 33 and the mounting groove 3.
[0024] By adopting the above technical solution, when there is a lot of water in the placement tank 33, it will flow down through the round hole 35 and be discharged outward through the drain hole 36. In addition, if the drain hole 36 is blocked, the water in the filter chamber 31 will not be able to be discharged outward and will flow upward from the round hole 35, so that the staff can discover the blockage of the drain hole 36 in time.
[0025] Several inclined blocks 21 that are compatible with inclined grooves 23 are symmetrically fixedly connected to both ends of the protective body 2.
[0026] By adopting the above technical solution, the inclined block 21 is fixedly connected to the protective body 2, thereby achieving the protective effect on the inclined groove 23.
[0027] The protective body 2 has symmetrically fixed transport ears 25 at the top near the center.
[0028] By adopting the above technical solution, the handling ear 25 provides a force application point for the handling and installation of the protective body 2, which facilitates the operator to transfer the protective body 2 and embed it into the hidden groove 22, reduces the installation difficulty of the protective body 2, and the protective body 2 itself is lightweight, so the staff can easily handle the protective body 2.
[0029] A filter screen 37 is provided at the end of the drain hole 36 away from the mounting groove 3.
[0030] By adopting the above technical solution, the filter screen 37 is located at the front end of the wall panel 1 to prevent large pieces of soil from being splashed (when vehicles drive near the retaining wall) into the drainage hole 36 and causing blockage.
[0031] A geotextile 32 is provided at the end of the filter chamber 31 away from the filter screen 37.
[0032] By adopting the above technical solution, the geotextile 32 has good permeability and filtration properties, which can prevent fine particles in the soil from entering the filter chamber 31 and avoid clogging of the sand and gravel filter layer.
[0033] Working principle: When using this device, first place the filter chamber 31 in the installation groove 3 in the wall panel 1 (the filter chamber 31 must contain sand and gravel to form a filter layer). Then, install geotextile 32 at the end of the filter chamber 31 away from the drainage hole 36. Next, place the wall panel 1 in the required position. When placing it, the protective body 2 on the wall panel 1 must first be removed from the hidden groove 22. Then, the rope is inserted through the inclined groove 23 into the appropriate lifting ring 24 to avoid stress damage during the hoisting process. Setting multiple lifting rings 24 and inclined grooves 23 can adjust the force of each lifting strap, thereby achieving multi-point uniform force (after hoisting, the protective body 2 must be reset to ensure the flatness of the top of the wall panel 1). When restoring the soil mound, the geotextile 32 should be in close contact with the soil mound, and soil-stabilizing plants (such as Virginia creeper and Amorpha fruticosa) should be planted on the placement trench 33. By planting soil-stabilizing plants, the backfill soil can be reinforced, while beautifying the environment. When there is water in the backfill soil (rainwater), the water will pass through the geotextile 32 and the filter chamber 31 to filter the soil, preventing the soil from flowing into the drainage holes 36 and causing blockage. Then, the water will be discharged outward through multiple drainage holes 36, thereby achieving the effect of draining the water in the backfill soil. This can reduce the soil moisture content, prevent the soil from increasing lateral pressure due to water accumulation, and thus improve the overall stability of the retaining wall structure.
[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
