Assembled embedded type prefabricated hollow underground continuous wall and construction method thereof

Abstract

The invention relates to an assembled embedded type prefabricated hollow underground continuous wall. The assembled embedded type prefabricated hollow underground continuous wall is formed by splicing a plurality of wall body units; each wall body unit comprises a wall body unit body, an upper connecting assembly and a lower connecting assembly; the wall body unit body is a hollow block body; the left side face of the wall body unit body is provided with a tenon; the transverse end surface of the tenon is a rectangle provided with an externally convex side wall, and the right side face of the tenon is a groove; the upper connecting assembly is formed by a right side opening groove body which is the same as the transverse end surface of the wall body unit body, a base plate and two L-type connecting blocks; the opening groove body is encircled by a connecting steel plate with a keyhole; an opening of the opening groove body is in inserting connection with the two L-type connecting blocks; the height of each L-type connecting block is half that of the connecting steel plate; the base plate is arranged at the top surface of the connecting steel plate, and is projected out of the outer edge of the connecting steel plate; wall body main ribs are welded on the base plate; the structures and shapes of the upper connecting assembly and the lower connecting assembly are completely the same; and the up-and-down splicing of the wall body unit is realized through bolts after the upper connecting assembly and the lower connecting assembly are in inserting connection. The assembled embedded type prefabricated hollow underground continuous wall has the advantages of shortening the construction period, improving the construction quality, reducing the probability of construction accidents, and the like.

Description

technical field [0001] The invention relates to an underground continuous wall and its construction method, in particular to a prefabricated underground continuous wall and its construction method. 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] The structural form of the underground diaphragm wall is generally a cast-in-place underground diaphragm wall. Since the cast-in-place underground diaphragm wall is poured underwater, the following defects and disadvantages inevitably...
