Summary:The utility model discloses a drainage device for a retaining wall. The drainage device comprises the retaining wall (1), an inverted omega-shaped drainage pipe (2), a sand bag (3) and coarse sand (4), the drainage pipe (2) is installed in the retaining wall (1), the sand bag (3) is cylindrical and tightly filled in the drainage pipe (2), the sand bag (3) integrally blocks a water inlet of the drainage pipe (2) and simultaneously extends into wall back filling soil of the retaining wall (1) by 10 cm, coarse sand (4) is filled in the sand bag (3), and the grain size of the coarse sand (4) is 1-4 mm. The drainage device overcomes the defects that in the prior art, drainage holes in a retaining wall are prone to blockage, drainage pipelines are not communicated, and the drainage holes of the retaining wall lose efficacy, and has the advantages that materials are few, the manufacturing cost is low, and the whole device can effectively save engineering investment while guaranteeing the good drainage effect. 本实用新型公
