Abstract

The invention discloses a retaining wall drainage system. The retaining wall drainage system comprises a plurality of drainage pipes, an inverted filter layer, a water leading pipe, a geogrid and geotextiles. A gap between the geogrid and a retaining wall body is filled with the inverted filter layer. Geotextiles are arranged on both sides of the inverted filter layer, the drainage pipes are arranged on the retaining wall body in a penetrating mode, and the water leading pipe is vertically arranged in the inverted filter layer between a retaining wall and earthwork. The water leading pipe communicates with partial drainage pipes to drain rainwater from the surface of soil, the drainage pipes which do not communicate with the water leading pipe discharge accumulating water inside the soil,and the geogrid is tied to the side, away from the retaining wall body, of the water leading pipe. The retaining wall drainage system has simple construction and smooth drainage.

Description

technical field [0001] The invention relates to the technical field of retaining wall drainage structure and construction, in particular to a retaining wall drainage system and a construction method for an anti-filter layer at the back of the wall. Background technique [0002] As a commonly used building, retaining wall has the functions of shore connection, water retaining, soil retaining, anti-seepage, etc., and is widely used in water conservancy and municipal engineering. Backfill earthwork is usually behind the retaining wall, and its lateral pressure is generally relatively large, especially after rains, the water in the earthwork is serious. If it is not discharged in time, it will easily cause the wall to overturn. Generally, it is necessary to set drainage pipes at intervals on the retaining wall body, and at the same time set an anti-filter layer behind the wall body. The material of the reverse filter layer is usually artificially screened graded gravel. [000...
