A prefabricated ground connection wall with angle steel joint limit and its construction method

Abstract

The invention discloses a prefabricated diaphragm wall adopting steel angle joint limitation and a construction method of the wall. The prefabricated diaphragm wall is formed through left-right splicing of inserted wall edges and to-be-inserted wall edges, and a limitation system for wall edges is arranged in the seam position of the prefabricated diaphragm wall; the limitation system comprises left-right limitation steel angles and front-rear limitation steel angle groups, and the inserted wall edges and the to-be-inserted wall edges are limited through clamping by means of the limitation system or ejection with the wall edges. According to the limitation system provided with the designed wall edges, the perpendicular mounting accuracy of the wall edges is adjusted through left-right limitation and front-rear limitation of the wall edges, so that the to-be-inserted wall edges are closely connected with the inserted wall edges from top to bottom, and the effects of wall perpendicularity control and effective water stop are realized in cooperation of swelling water stop strips and a detachable waterproof device.

Description

technical field [0001] The invention belongs to the field of enclosure construction under buildings, and in particular relates to a prefabricated ground connecting wall which can limit its position independently. Background technique [0002] With the rapid development of the economy and the continuous improvement of the level of urbanization, urban problems have become increasingly prominent, such as dense population, traffic congestion, exhaustion of resources, insufficient usable area, and high land prices. Using underground space to configure urban infrastructure is an effective way to fundamentally solve the problem of urban development. At present, the most commonly used underground space enclosure structure is the underground diaphragm wall. [0003] However, since the cast-in-place underground diaphragm wall is poured underwater, there are inevitably some defects and disadvantages. [0004] 1. Waiting for the concrete to solidify leads to an extension of the constr...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to provide a prefabricated ground connection wall with angle steel stud joint limit and its construction method, which solves the problem of prolonging the construction period caused by waiting for the concrete to solidify in the cast-in-place ground connection wall, difficult quality assurance during pouring, and smooth wall surface in weak ground It also solves the technical problem that the installation position and installation effect of the prefabricated floor-connected wall are not easy to control and there are deviations, resulting in poor water-stop effect at the joints and difficult to guarantee the connection effect of the wall
