Basement construction method based on socket type steel plate water stop belt

Abstract

The invention discloses a basement construction method based on a socket type steel plate water stop belt. The basement construction method comprises the following steps of 1, basement bottom plate construction, specifically, 101, a post-cast strip indwelling construction structure is constructed, and steel bars are bound; 102, concrete pouring is carried out; 103, the post-cast strip indwelling formwork is removed; 104, post-cast strip concrete pouring is carried out; 2, bearing structure construction; and 3, basement roof construction. According to the basement construction method, construction is easy and convenient, a left post-cast strip water stop and positioning structure and a right post-cast strip water stop and positioning structure are adopted in the post-cast strip indwelling construction structure, the steel plate water stop belt is connected in a socket and spigot joint mode, positioning and fixing are conducted from the two sides through a water stop belt positioning mechanism, the work efficiency can be effectively improved, and the waterproof quality can be guaranteed; meanwhile, a top barrier strip and a bottom barrier strip are arranged on the upper side and the lower side of the water stop belt positioning mechanism correspondingly, a steel bar protection layer cushion block can be replaced, the water stop belt positioning mechanism can be matched to form a post-cast strip indwelling formwork, and the construction process of the basement structural slab with the reserved post-cast strip can be completed easily, conveniently and rapidly with high quality.

Description

technical field [0001] The invention belongs to the technical field of basement construction, and in particular relates to a basement construction method based on a socket-type steel plate waterstop. Background technique [0002] The basement refers to the height of the room floor below the outdoor ground level exceeding half of the clear height of the room. Multi-storey and high-rise buildings require a deep foundation. In order to take advantage of this height, a basement is built under the ground floor of the building, which can increase the usable area, improve the efficiency of building land, and save the backfilling of the center of the building, which is economical and practical. The outer wall and floor of the basement are deeply buried in the ground and are infiltrated by water in the soil and groundwater. Therefore, the problem of moisture and water resistance is an important problem to be solved in the design of the basement. Post-pouring strips are used to preve...

AI Technical Summary

Problems solved by technology

However, the traditional post-cast belt formwork support method currently adopted is to use wooden formwork support or steel wire mesh to block, the construction process is relatively cumbersome, and the wood formwork, steel wire mesh and other materials used are mostly one-time investment. Destructive demolition will generate a lot of garbage, high input cost, and serious waste of materials

At the same time, the overall installation and dismantling process is complicated, time-consuming and labor-intensive, which affects the construction period, and the apparent quality of the concrete after pouring is poor
