Problems solved by technology

The support engineering is independently designed according to different geology, and the engineering volume is large, the cost is high, and the construction period is long
Long-term storage of some supports will have adverse effects on the environment
If the outer wall of the basement is constructed first, most of the supporting works can be saved. The existing punching and drilling process for pouring the underground diaphragm wall is not widely used because of its high cost, long construction period, and uneconomical cost calculation. use

Abstract

The invention relates to a precast pressed-in underground continuous wall and a construction method thereof. The continuous wall is formed by a precast corner wall body and a straight wall body, which are precast by reinforced concrete, in a split joint manner, wherein the two end parts of both the corner wall body and the straight wall body are respectively a first connecting part, a second connecting part, a third connecting part and a fourth connecting part, which serve as a front-end connecting part or a back-end connecting part; during performing split joint, the front-end connecting part is in split joint with the adjacent back-end connecting part, and a combined cavity is formed by a concave inner cavity of the front-end connecting part and a concave inner cavity of the back-end connecting part in a surrounding manner; and concrete is poured into the combined cavity the combined cavity. As the corner wall body and the straight wall body of the continuous wall adopt industrialized production, the continuous wall has high production efficiency, lower cost, simple construction process and short construction period.

Description

technical field [0001] The invention relates to a prefabricated pressed-in underground continuous wall and a construction method thereof. Background technique [0002] At present, most of the basement structure construction is carried out before the excavation of the earthwork, and the earthwork support engineering construction that is larger than the volume of the basement structure is carried out. The supporting engineering is designed independently according to different geology, and the engineering volume is large, the cost is high, and the construction period is long. Long-term storage of some supports will have adverse effects on the environment. If the outer wall of the basement is constructed first, most of the supporting works can be saved. The existing punching and drilling process for pouring the underground diaphragm wall is not widely used because of its high cost, long construction period, and uneconomical cost calculation. use.
