Underground continuous wall of chain prefabricated pile

Abstract

The invention discloses an underground continuous wall of a chain prefabricated pile, and relates to the technical field of underground continuous walls. The underground continuous wall comprises a first prefabricated pile body, wherein the right side of the first prefabricated pile body is movably connected with a second prefabricated pile body, a triangular groove is formed in the right side ofthe first prefabricated pile body, and the left side of the second prefabricated pile body is fixedly connected with a triangular protrusion. According to the underground continuous wall, the first prefabricated pile body and the second prefabricated pile body are laterally aligned by providing the triangular protrusion and the triangular groove; by arranging a first half square groove, a second half square groove and a square steel bar frame, a gap at the joint can be removed, and a mounting block, a thread groove and a threaded column are used, so that the first and second prefabricated pilebodies are longitudinally aligned; a connecting key is formed after pouring, and finally a first reinforcing cage and a second reinforcing cage are used for integral pouring, so that the joints of the two prefabricated piles are aligned without any gap, and the stability of the underground continuous wall is improved.

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
