Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls, in particular to a prefabricated and assembled gravity retaining wall structure. Background Art

[0002] Gravity retaining walls are widely used in geotechnical engineering. They rely on their own gravity to resist the soil pressure behind the wall. The wall body is generally cast on site with plain concrete. They are widely used in my country's railway, highway, water conservancy, port, mining and other projects. Since gravity retaining walls rely on their own weight to maintain balance and stability, they are large in size and weight, and can maintain balance only by their own weight, so the force is stable and reliable.

The entire construction process requires a large number of workers to work on-site for a long time, resulting in long construction periods and difficult maintenance, which leads to slow overall construction efficiency. In addition, the wall usually uses its own gravity to maintain stability, has a small contact area with the ground and the retaining wall, and has low support strength. Utility Model Content

[0030] For example, see Figures 1 to 6The utility model provides a prefabricated gravity retaining wall structure, comprising:

[0031] A base 1, a wall is installed on the surface of the base 1, and the wall is composed of a plurality of prefabricated blocks 2, one side of the prefabricated block 2 is fixedly connected with a dovetail block 11, and the other side is provided with a dovetail groove 204 adapted to the dovetail block 11;

[0032] Insert block 3, a hollow groove 201 is formed on the surface of prefabricated block 2, and insert block 3 is fixedly connected to the bottom of prefabricated block 2, and insert block 3 is adapted to hollow groove 201;

[0033] A limiting component, which is arranged in the prefabricated block 2 and includes a movable plate 7;

[0034] The bottom plate 13 has two symmetrically distributed fixing plates 15 fixedly connected to its surface, a connecting plate 16 is hingedly connected between the two fixing plates 15, and the connecting plate 16 is connected to the prefabricated block 2 via a supporting component.

[0035] In this embodiment, the prefabricated blocks 2 and other accessories produced in advance are transported to the construction site, and then they can be installed. During installation, the dovetail block 11 on one side of the prefabricated block 2 is aligned with the dovetail groove 204 of the other prefabricated block 2, and then the dovetail block 11 is inserted into the dovetail groove 204 in a vertical installation manner, thereby completing the installation of two adjacent prefabricated blocks 2. During vertical installation, the insert block 3 is inserted into the empty groove 201. Fillers can be injected into the empty groove 201 before installation, which can reduce the dead weight of the structure and facilitate transportation, so that the prefabricated block 2 reaches a certain weight and increases the retaining effect. After the insert block 3 is inserted into the empty groove 201, it moves through the limiting component, and the insert block 3 is limited to complete the vertical installation. There is no need for other operations such as pouring concrete on site, which reduces the construction period, improves the construction efficiency, and can be recycled. Figure 1 and Figure 5 As shown, after the gravity retaining wall is installed, the connecting plate 16 on the bottom plate 13 is connected to the prefabricated block 2 through the supporting components to increase the contact area between the gravity retaining wall and the ground and soil, improve the supporting strength, and enhance the stability of the retaining wall.

[0036] The limiting components include:

[0037] The rotating rod 6 is fixedly connected to the surface of the prefabricated block 2 with a fixed block 20, the surface of the fixed block 20 is provided with a through hole for the rotating rod 6 to pass through and be slidably connected thereto, the surface of the rotating rod 6 is provided with a threaded portion 9, and the end of the rotating rod 6 is fixedly connected to an end plate 8;

[0038] A slide groove 203 is provided on the surface of the prefabricated block 2 for the movable plate 7 to extend into, and the movable plate 7 is slidably connected to the prefabricated block 2 through the slide groove 203. A threaded hole one is provided on the surface of the movable plate 7 for the threaded portion 9 to pass through and be threadedly connected thereto, and a plurality of limit rods 10 are evenly distributed on the surface of the movable plate 7.

The movable plate 7 moves and drives the limit rod 10 to move. Since the insert block 3 is inserted into the empty groove 201 at this time, it moves with the limit rod 10 and can gradually extend into the limit groove 301, thereby limiting the insert block 3 and achieving the effect of vertical installation. At the same time, the insert block 3 extending into the empty groove 201 can compact the filling in the empty groove 201, reduce the gap, and ensure the stability of the retaining wall.

The wall is auxiliary supported by the telescopic plate 17, the connecting plate 16 and the bottom plate 13, thereby increasing the contact area between the gravity retaining wall and the ground, improving the support strength, and enhancing the stability of the gravity retaining wall.

[0044] Embodiment 2, further, the number of dovetail blocks 11 and dovetail grooves 204 are both two, and both are symmetrically distributed.
