Description

Active drainage mechanism of retaining wall

Technical Field

The utility model relates to the technical field of drainage, in particular to an active drainage mechanism of a retaining wall.

Background

When a tunnel is excavated or a large foundation pit is excavated or a mountain road is constructed, loose soil is generated more or less, and a piling mode is adopted. Because the soil is not original ecological geology, the soil has higher looseness, and the problems of landslide and the like are easy to occur in rainy seasons or when water leakage is more. In addition, at the side slope of the mountain area (newly built road or building foundation pit), the original surface soil is removed, so that the side slope has the problems of landslide and the like. Therefore, in slope protection, a retaining wall is also adopted to shield loose soil; however, the problems of landslide and the like caused by water seepage or rainwater are not solved in the prior art.

Moreover, drainage systems in the prior art mostly adopt drainage ditches or drainage pipes for drainage, and the drainage ditches are easy to be blocked, namely loose soil falls or sundries are accumulated, and the like. Therefore, drainage in the prior art is unreliable.

Therefore, there is an urgent need to provide an active drainage mechanism for a retaining wall with simple structure, reliable drainage and high supporting strength.

As shown in fig. 1 to 5, the present embodiment provides an active drainage mechanism for a retaining wall, which is pre-buried in the geology of the area where the retaining wall is located, and gathers and drains the water that seeps down from the geology, so as to effectively avoid the landslide problem caused by too much water in the geology, and the problem of blockage does not exist.

Specifically, the active drainage mechanism of the present embodiment includes a water collecting pipe 1 laid along the length direction of the retaining wall, a drain pipe 2 provided at the end of the water collecting pipe 1 and penetrating the bottom of the retaining wall and guiding out water in the water collecting pipe 1, a plurality of joint pipes 3 provided on the water collecting pipe 1, and an active drain pipe 4 connected to the joint pipes 3. Wherein the active drain pipe 4 collects water in the geology of the area where the retaining wall is located and gathers in the water collecting pipe 1.

In this embodiment, the active drain pipe 4 includes a drain pipe body 41, a plurality of water suction holes 411 formed on an upper surface of the drain pipe body 41, a geotechnical cloth layer 45 laid on the drain pipe body 41 and covering the water suction holes 411, a filter plate 43 disposed in the drain pipe body 41 and disposed at a lower portion of the water suction holes 411, a support plate 44 disposed at a bottom portion of the filter plate 43, a tapered front end portion 42 disposed at a front end of the drain pipe body 41, and an end collar 46 disposed at an end portion of the geotechnical cloth layer 45, wherein the end collar 46 is wrapped on the geotechnical cloth layer 45 and the drain pipe body 41. In this embodiment, a plurality of filter holes are provided in the filter sheet 43.

In the present embodiment, the two sides of the inner wall of the drain pipe body 41 are respectively provided with a clamping groove 412, and the filter plate 43 is placed in the clamping groove 412. Wherein the cross sections of the filter plate 43 and the support plate 44 are T-shaped; in this way, it is achieved that the filter plate 43 and the support plate 44 are pressed into the drain pipe body 41. The filter plate 43 and the support plate 44 provide support for the drain body 41 and also prevent the drain body 41 from being blocked due to collapse of the upper portion of the drain body 41. That is, the upper portion of the drain pipe body 41 is provided with a plurality of water suction holes 411, so that the supporting strength of the upper portion of the drain pipe body 41 becomes weak, and as the use time goes by, the upper portion of the drain pipe body 41 may be crushed by soil, thus leading to unreliable active drainage. In this embodiment, by providing the filter plate 43 and the support plate 44, the filter plate is in a T shape, which has the advantages of high support strength, stability, reliability, and the like, even if the upper portion of the drain pipe body 41 is crushed, the lower portion is still intact, and the function of collecting water seepage is still provided.

In addition, the joint pipe 3 of the present embodiment is connected with the water collecting pipe 1 by sealing glue, and the drain pipe body 41 is arranged vertically to the water collecting pipe 1. In the embodiment, according to the slope angle of the on-site geology and the arrangement position of the active drainage, the relative position of the joint pipe 3 and the water collecting pipe 1 is adjusted, and the elevation angle of the active drainage pipe 4 is adjusted. As shown in fig. 1, the active drain pipe 4, the water collecting pipe 1 and the drain pipe 2 are not on the same horizontal plane, and the active drain pipe 4 has an elevation angle with the plane of the water collecting pipe 1 and the drain pipe 2. For example, the slope of the earth of the area where the retaining wall is located is 45 °, and then the elevation angle of the plane where the active drain pipe 4 and the water collecting pipe 1 and the drain pipe 2 are located may be set to be 30 ° to 45 °, and the elevation angle is determined according to the site situation, so long as the installation is convenient, and water seepage can be collected, which will not be described herein.

The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, but all changes made by adopting the design principle of the present utility model and performing non-creative work on the basis thereof shall fall within the scope of the present utility model.
