Method of constructing underground diaphragm wall by cement deep mixing

Abstract

The invention discloses a method of constructing an underground diaphragm wall by cement deep mixing. The method includes: clearing a site and preparing materials; setting out and performing high jointing; mounting and regulating; trenching and laying plates; moving a machine and positioning; grouting, advancing and mixing; performing rotation mixing and lifting; forming a wall and removing the machine. The method has the advantages that the method is advanced; the wall has good continuity, integrity and impermeability; cement mixing volume in the depth direction meets the design requirements, mixing is even with compactness, and the wall is high in quality; the wall formed has high depth and small wall thickness; the use of split independent drive requires low energy consumption; stability is good and vertical accuracy is high; inner and outer drill pipes are good in concentricity and tightness; the structure is compact and fast and convenient to remove; strength is high and bearing capacity is high; work efficiency is high and manufacturing cost is low; the quality is good and environmental influence is low.

Description

technical field [0001] The invention relates to a construction method for deep mixing cement land connecting walls, belonging to the technical field of building construction. Background technique [0002] In recent years, my country's urbanization has developed rapidly, and high-rise buildings in various cities have sprung up like mushrooms. In the construction of the soil layer containing or mixed with egg (crushed) stones with a particle size not greater than 10cm, there are still problems such as poor continuity, insufficient integrity and poor anti-permeability of the constructed diaphragm wall. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the construction of the land continuous wall in the current building construction, and provide a construction method of the deep mixing cement land continuous wall to solve the above-mentioned problems. [0004] In order to achieve the above object, the technical scheme ...
