Abstract

The invention provides an optimization treatment structure for construction of a post-pouring belt of a bottom plate. A raft plate at the post-pouring belt is partly lowered by 150-300 mm to form a drainage canal, two groups of parallel steel wire mesh supports are vertically arranged in the drainage canal in the length direction, vertical steel wire meshes are arranged on the steel wire mesh supports in the length direction of the drainage canal, and concrete is poured on the outer sides of the two groups of steel wire mesh supports, so that the problem of complicated construction process ofthe post-pouring belt is solved and the structure quality and anti-seepage effect of the post-pouring belt are improved. The structure belongs to the technical field of building construction.

Description

technical field [0001] The invention relates to a base plate post-cast belt construction optimization treatment structure, which belongs to the technical field of civil foundation construction. Background technique [0002] At present, taking the first phase of the Shigang resettlement area of ​​Huadu central axis (southern area) as an example, the basement of the main building of the main project and the floor of the garage are the same form of 600mm thick raft foundation, and the construction area of ​​the underground garage area and the main building area is about 6 10,000 square meters, with a vertical and horizontal length of about 250m. In order to reduce the settlement change of the main building perimeter and the garage floor and the tensile stress caused by the temperature shrinkage change during construction, post-cast strips for the bottom slab are installed in both vertical and horizontal directions of the bottom slab. The post-cast strips are set at an interval ...
