Abstract
The invention discloses a post-cast strip construction and drainage method for a base plate of a basement. The method is characterized by comprising the following steps: a) prefabricating a permeable tube and a cover plate; b) pre-burying the permeable tube and the cover plate; c) draining a post-cast strip; d) constructing post-cast strip concrete; e) preserving the concrete. With the adoption of a scheme that a permeate well is arranged in the post-cast strip of the base plate of the basement, the method disclosed by the invention not only can meet the collection and the discharge of surface water, but also meet the permeation and the discharge of underground water. The construction of the post-cast strip of the base plate and the combination with a pre-cast base plate are facilitated, and the method has the advantages of simplicity in construction and good permeation and discharge effects. Furthermore, the probability of leakage of the post-cast strip of the base plate is greatly reduced.
