Stack pouring type underground diaphragm wall and construction method thereof

Abstract

The invention provides a stack pouring type underground diaphragm wall and a construction method thereof, and relates to the technical field of building construction. A plurality of prefabricated unitwalls and cast-in-place concrete walls are arranged; the prefabricated unit walls comprise internal wallboard parts and external convex beam parts; the two external convex beam parts are arranged onthe outer sides of the internal wallboard parts in the width direction at intervals; the prefabricated unit walls are sequentially distributed in a deep slot on the periphery of a foundation pit in the length direction; a groove structure is formed in the external convex beam parts arranged oppositely between the adjacent prefabricated unit walls; and the cast-in-place concrete walls are poured inthe groove structure, so that blocking of joints between the adjacent prefabricated unit walls is realized. According to the stack pouring type underground diaphragm wall and the construction methodthereof, through the prefabricated unit walls, the flatness of the internal wall surface is guaranteed, waterproof work is easy to carry out later, the structural integrity is good, an effective protecting role can be played, and the construction efficiency is greatly improved; and the integral structure is simple and novel, the design is ingenious, processing convenient, and more economical and practical are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a stacked underground continuous wall and a construction method thereof. Background technique [0002] The underground diaphragm wall is a long and narrow deep groove excavated on the ground along the peripheral axis of the deep excavation project under the condition of the mud retaining wall. After the groove is cleaned, the steel cage is hung in the groove , and then use the conduit method to pour underwater concrete to build a unit trough section, each unit trough section generally does not exceed 6 meters, and so on section by section until a closed reinforced concrete wall is formed along the circumference of the project to be built, as a cut-off For the enclosure structure of water and soil retaining, after the concrete reaches a certain age, the internal soil is taken out by digging side braces to construct the underground structure. Generally speaking, unde...
