Underground continuous wall with socket-type steel lattice framework and construction method thereof

Abstract

The invention relates to the technical field of underground continuous wall construction, and discloses an underground continuous wall with a socket-type steel lattice framework and a construction method thereof. The underground continuous wall comprises a framework structure and concrete, wherein the framework structure is formed by arranging first lattice columns and second lattice columns at intervals in a staggered manner; the first lattice columns and the second lattice columns are in socket connection; each first lattice column comprises a first end part vertical rod positioned at the end corner of the periphery of a rectangle and a rectangular frame belt arranged at the periphery of the first end part vertical rod in a surrounding manner; each second lattice column comprises a second end part vertical rod positioned at the end corner of the periphery and a surrounding frame structure arranged at the periphery of the second end part vertical rod in a surrounding manner; the surrounding frame structure consists of a pair of short steel belts and a pair of long steel belts; after being fixed with the outer side walls of the second end part vertical rods on the two sides, the plate surfaces at the two ends of each long steel belt horizontally extend outwards to form an inserting groove with the corresponding long steel belt; the first lattice columns are inserted into the inserting groove in a matched manner. The framework is assembled in blocks, so that the underground continuous wall is quick and accurate in positioning, low in hoisting difficulty and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of underground diaphragm wall construction, in particular to an underground diaphragm wall with a socket-type steel lattice frame and a construction method thereof. Background technique [0002] With the rapid development of the global economy and the introduction of China's urbanization policy, a large number of people have poured into the city, cities around the country are expanding rapidly, the metropolitan area is full of vitality, and the flow of people is becoming more and more dense. The convenience and comfort of high-paced life for transportation The requirements are getting higher and higher, and the rail transit characterized by "fast, punctual, comfortable, safe, environmentally friendly, and large capacity" is particularly important here. The rail transit network plans of major cities across the country have been introduced one after another, and the construction of rail transit in various place...

AI Technical Summary

Problems solved by technology

[0005] The technical problems to be solved are: the inner skeleton of the traditional underground diaphragm wall is a steel cage, and there are many construction restrictions, the overall hoisting is difficult, the block hoisting and positioning connection is difficult, and the bearing capacity is low
