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] Prefabricated retaining walls are a type of retaining structure that is assembled on-site from prefabricated components such as retaining bricks, wall panels, and foundation blocks manufactured in a factory. They are mainly used to resist lateral soil pressure and stabilize slopes, and are widely used in road, water conservancy, municipal, and building foundation pit projects.

[0003] Chinese Patent Publication No. CN221523635U discloses a prefabricated retaining wall structure, including a retaining brick body with a hollow interior. Multiple through cavities are formed on the surface of the retaining brick body, and a snap-fit ​​structure is provided on the surface to lock multiple retaining brick bodies in place. An I-shaped groove is provided on the top surface of the retaining brick body, allowing the brick body to be inserted into the top surface of another retaining brick body located below it via an insert block. This embeds the insert block into the I-shaped groove, enabling the stacking of the retaining wall. Since the number of I-shaped grooves on the same side of the retaining brick body is two more than the number of insert blocks, operators can selectively insert insert blocks into different positions on the top surface of another retaining brick body, allowing for front-to-back adjustment of the retaining wall to adapt to different installation requirements, improving the working environment of the retaining wall and increasing the installation efficiency of the operators.

[0004] In the aforementioned prior art, multiple I-shaped grooves and inserts can be set on the upper and lower retaining bricks for splicing. By inserting the inserts on the retaining bricks into different I-shaped grooves, the installation style of the retaining wall can be adjusted to improve the landscape effect. However, the distribution distance of the I-shaped grooves and inserts is fixed, and can only be adjusted at fixed intervals. This results in the final retaining wall curve being a broken line segment connected by a series of short straight lines, which may not look natural when viewed up close and has a difference in aesthetics.

[0005] Therefore, it is necessary to propose a prefabricated retaining wall structure to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated retaining wall structure to solve the problem mentioned in the background art that the distribution distance of the retaining brick I-shaped groove and the insert is fixed and can only be adjusted at a fixed interval, so that the final curve is actually a series of short straight lines connected into a broken line segment, which may not look natural and has a difference in aesthetics when viewed up close.

[0026] 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.

[0027] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a prefabricated retaining wall structure, including a plurality of retaining bricks 100. A positioning box 200 is installed inside the retaining brick 100. An adjusting seat 201 is slidably installed inside the positioning box 200. A positioning structure is connected to the adjusting seat 201. The positioning structure is used to position and splice the upper and lower retaining bricks 100, and also facilitates fine adjustment. A grouting structure is connected to the positioning box 200. The grouting structure is used to reinforce the retaining bricks 100 after splicing. A connecting hole 400 is opened inside the retaining brick 100. A reinforcing structure is connected to the connecting hole 400. The reinforcing structure needs to cooperate with the grouting structure to reinforce the splicing of the side retaining bricks 100.

[0028] Furthermore, the positioning structure includes a positioning hole 202, which is located inside the adjusting seat 201. A positioning steel bar 203 is installed on one side of the retaining brick 100. The positioning steel bar 203 is adapted to the positioning hole 202. When splicing the retaining brick 100, the positioning steel bar 203 of the upper retaining brick 100 can be aligned with the positioning hole 202 of the lower brick and inserted for positioning.

[0029] Furthermore, an adjusting screw 204 is rotatably installed inside the positioning box 200. One end of the adjusting screw 204 is threaded inside the adjusting seat 201. By rotating the adjusting screw 204 on the lower retaining brick 100, it can be driven to move horizontally through the threaded engagement with the adjusting seat 201, so that the adjusting seat 201 can move horizontally with the upper retaining brick 100 through the positioning hole 202.

[0030] Example 2: Figure 1-6 To further enhance the connection stability of the retaining bricks 100, a grouting structure and a reinforcement structure were arranged. The grouting structure includes grouting holes 300, which are located inside the positioning box 200. Several connecting grooves 301 are provided on the adjusting seat 201, and several annular grooves 302 are provided on the positioning steel bars 203. A stake 303 is installed on one side of the retaining brick 100, and a filling hole 305 is provided inside the retaining brick 100. The stake 303 corresponds to the filling hole 305. A guide channel 304 is provided on the positioning box 200. 4. It is connected to the filling hole 305. After splicing, cement grout can be injected into the grouting hole 300. The grout can enter the space between the two retaining bricks 100 through the grouting hole 300, i.e. the position of the positioning steel bar 203. It flows to the space on both sides of the adjusting seat 201 through the connecting groove 301 for filling. After the grout solidifies, it can restrict the position of the adjusting seat 201 to prevent the upper and lower retaining bricks 100 from shifting. Some grout flows from the guide groove 304 into the filling hole 305 and fills both sides of the inserted pile 303. After the grout solidifies, it can fix the position of the inserted pile 303.

[0031] The reinforcement structure includes connecting piles 401, which correspond to connecting holes 400. Connecting holes 400 are connected to filling holes 305. Connecting piles 401 are installed on one side of retaining bricks 100. Several strip grooves 402 are provided on both connecting piles 401 and insert piles 303. When the retaining bricks 100 on the side are spliced, the corresponding connecting piles 401 can be inserted into the connecting holes 400. Some grout can flow into the connecting holes 400 through the filling holes 305 and fill the side of the connecting piles 401. During the grouting process, the grout will fill the annular grooves 302 on the positioning steel bars 203 and the strip grooves 402 on the insert piles 303 and connecting piles 401, so that after the grout solidifies, it can form an obstacle to the positioning steel bars 203, insert piles 303 and connecting piles 401, thereby improving the splicing stability of the retaining bricks 100.

[0032] The working principle is as follows: The retaining brick 100 can be cast in a factory using concrete and molds. During casting, positioning boxes 200 and positioning steel bars 203 are embedded at corresponding positions. When assembling the retaining bricks 100, the positioning steel bars 203 of the upper retaining brick 100 can be aligned with the positioning holes 202 of the lower retaining brick 100 and inserted. Simultaneously, the stakes 303 of the upper retaining brick 100 are inserted into the filling holes 305 of the lower retaining brick 100. (Refer to...) Figure 4 After completion, rotating the adjusting screw 204 on the lower retaining brick 100 allows it to move horizontally through its threaded engagement with the adjusting seat 201. This enables the adjusting seat 201 to move horizontally with the upper retaining brick 100 via the positioning hole 202. As the retaining brick 100 moves, the inserted stake 303 can move within the filling hole 305 to fine-tune the splicing position of the retaining brick 100. When splicing the side retaining bricks 100, the corresponding connecting stake 401 can be inserted into the connecting hole 400. After completion, cement grout can be injected into the grouting hole 300. The grout enters the space between the two retaining bricks 100, i.e., the position of the positioning steel bar 203, through the grouting hole 300. (Refer to...) Figure 5 The grout then flows through the connecting channel 301 to fill the space on both sides of the adjusting seat 201. Then, some of the grout flows from the guide channel 304 into the filling hole 305 and fills both sides of the inserted pile 303. After that, it flows through the filling hole 305 into the connecting hole 400 and fills the side of the connecting pile 401. During the grouting process, the grout will fill the annular groove 302 on the positioning steel bar 203 and the strip groove 402 on the inserted pile 303 and the connecting pile 401. After the grout solidifies, it can form an obstacle to the positioning steel bar 203, the inserted pile 303 and the connecting pile 401, so as to improve the connection stability of the upper and lower retaining bricks 100 and the side retaining bricks 100.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
