Retaining wall drain pipe reversed filter structure

Abstract

The invention provides a retaining wall drain pipe reversed filter structure. The retaining wall drain pipe reversed filter structure comprises a water collecting part and a filter part fixed to the water collecting part. The filter part is a filter bag filled with a filter material. The combined face of the filter part and the water collecting part is a slope. At least one guide blind hole allowing a drain pipe to be inserted therein is formed in the low side corresponding to the slope between the filter part and the water collecting part. The water collecting part and the filter part are fixed into a whole, and the guide blind holes are formed in the low side of the combined face of the filter part and the water collecting part. In the using process, the drain pipe is inserted into the guide blind holes, the retaining wall drain pipe reversed filter structure is installed on the drain pipe, and filtered water of the inner side of a retaining wall flows downwards along the inclined combined face between the water collecting part and the filter part to the guide blind holes, enters the drain pipe, and is drained to the outer side of the retaining wall. The retaining wall drain pipe reversed filter structure can be quickly mounted or demounted on the premise that the filter and water collecting effects are guaranteed without at the same time of retaining wall construction, the construction progress of the retaining wall is not affected, and use is very convenient.

Description

technical field [0001] The invention relates to a retaining wall drainage system, in particular to a retaining wall drainage pipe reverse filter structure. Background technique [0002] The traditional reverse filter structure of the retaining wall drainage pipe is in the form of hard clay half-wrapped coarse particle filter material, that is, the positions corresponding to the drainage pipes on the retaining wall are piled with hard clay to pile up multiple sumps, and filter filters are set in the sumps. The seepage water is filtered through the filter material and then discharged to the outside of the retaining wall through the drain pipe. [0003] However, the existing retaining wall drainage pipe filter structure must be completed on site, which affects the overall construction progress of the retaining wall, and the construction quality is difficult to guarantee, and it is easy to be damaged during the rolling stage of the construction process, which is difficult to mee...
