Retaining wall reverse filter drain hole embedded part and construction method thereof

Abstract

The invention discloses a retaining wall reverse filter drain hole embedded part, which comprises a sleeve, one or more drain reverse filter layers and two or more permeable layers. The drain reversefilter layers are arranged in the sleeve in a transverse interception mode so as to further intercept water flowing through the interior of the sleeve, and the two permeable layers coat the two ends of the sleeve correspondingly to filter the water flowing into the sleeve. The retaining wall reverse filter drain hole embedded part is simple and stable in structure, and environmentally friendly, the construction cost can be effectively lowered, the construction quality of a retaining wall reverse filter structure can be effectively guaranteed, and the reverse filter efficiency of a retaining wall and the construction efficiency of wall back earthwork backfilling are improved.

Description

technical field [0001] The invention relates to the field of drainage of retaining walls, in particular to a pre-embedded part of a reverse filter drainage hole of a retaining wall and a construction method thereof. Background technique [0002] existing technology by figure 1 It shows that the filter structure of the retaining wall is mainly composed of the retaining wall drain hole 1A and the filter layer or filter bag 2A behind the wall. The drain hole is a PVC hard pipe with a diameter of about 100mm, and the filter layer or filter bag is For weakly permeable fillers, the construction process of the traditional filter layer or filter bag is complicated and the investment is large. There is a lot of interference with the earthwork backfill construction behind the retaining wall, and the construction quality of the filter layer or filter bag is difficult to guarantee. Therefore, a new type of retaining layer is needed. The embedded parts of the earth wall weep hole can ma...

[0002] existing technology by figure 1 It shows that the filter structure of the retaining wall is mainly composed of the retaining wall drain hole 1A and the filter layer or filter bag 2A behind the wall. The drain hole is a PVC hard pipe with a diameter of about 100mm, and the filter layer or filter bag is For weakly permeable fillers, the construction process of the traditional filter layer or filter bag is complicated and the investment is large. There is a lot of interference with the earthwork backfill construction behind the retaining wall, and the construction quality of the filter layer or filter bag is difficult to guarantee. Therefore, a new type of retaining layer is needed. Earth wall weep hole embedded parts to make up for this deficiency
