A kind of foundation pit engineering stiff concrete support device

Abstract

The utility model discloses a kind of foundation pit engineering stiff concrete support devices, including one or several horizontal support components arranged along the length direction of foundation pit, horizontal support component includes steel support by upper reinforcement, lower reinforcement, left reinforcement, right reinforcement and tail reinforcement splicing, and the steel support for the upper and lower left and right direction of steel support is placed in steel support along the inner center position of steel support, steel support is arranged around foundation pit, steel support is hollow structure, the gap of right side of steel support and left reinforcement is same with the gap of left side of steel support and right reinforcement, the bottom connecting node of steel support is welded by patching plate with the vertical lattice column of interval arrangement pre-buried in the bottom of foundation pit along the length direction of foundation pit, and steel support is poured with concrete on steel support and forms stiff reinforced concrete support, so that steel support finally supports stiff reinforced concrete support.
