An underground continuous wall of interlocking prefabricated piles

Abstract

The invention discloses an underground continuous wall of interlocking prefabricated piles. There is a triangular groove, the left side of the second prefabricated pile body is fixedly connected with a triangular bump, and the invention relates to the technical field of underground continuous walls. In the underground continuous wall of interlocking prefabricated piles, the first prefabricated pile body and the second prefabricated pile body are horizontally aligned by arranging triangular bumps and triangular grooves, and by arranging the first half-square groove, the second half-square groove and the square steel bar It can deal with the gap at the connection, and then use the installation block, threaded groove and threaded column to align it longitudinally, and form the connection key after pouring, and finally cooperate with the first reinforcement cage and the second reinforcement cage to pour as a whole. The connection of the two prefabricated piles is aligned without creating a gap, which enhances the stability of the underground continuous wall.

Description

technical field [0001] The invention relates to the technical field of underground diaphragm walls, in particular to an underground diaphragm wall of interlocking prefabricated piles. Background technique [0002] The underground diaphragm wall is a kind of trenching machine used on the ground for basic engineering. Along the peripheral axis of the deep excavation project, a long and narrow deep trench is excavated under the condition of mud retaining wall. After the trench is cleaned, it is hung in the trench Reinforcement cages, and then use the conduit method to pour underwater concrete to form a unit trough section. In this way, a continuous reinforced concrete wall is built underground as a water interception, anti-seepage, load-bearing, and water-retaining structure. Because in the city, the foundation pit project is often constructed in the downtown area, not only to ensure the stability and safety of the foundation pit itself, but also to control the ground settlemen...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an underground continuous wall of interlocking prefabricated piles, which solves the problem that in the existing underground continuous wall of interlocking prefabricated piles, the joints of the two prefabricated piles cannot be aligned, and deviations tend to occur during installation. shift, resulting in poor stability of the underground diaphragm wall
