Assembly type retaining structure connecting device and connecting method thereof

Abstract

The invention discloses an assembly type retaining structure connecting device. The assembly type retaining structure connecting device comprises a plurality of support piles which are vertically arranged, wherein at least one horizontally placed type profile steel assembly waist beam is at least arranged in a length direction of the support piles in a position, away from a rock-soil body, in themultiple support piles; a plurality of earth-retaining component connectors are uniformly arranged in a gap of the profile steel assembly waist beam; the earth-retaining component connectors are in one-to-one correspondence to the support piles; the other ends of the earth-retaining component connectors are blocked on the corresponding support piles; an anchor cable is arranged between adjacent two support piles; a plurality of steel strands are fixedly arranged in the anchor cables; and the other ends of the multiple steel strands pass through the gap of the profile steel assembly waist beamand are connected to anchorage devices. The assembly type retaining structure connecting device disclosed by the invention solves the problems that a steel waist beam in the prior art easily has torsion and local turn-back unstable phenomena due to the fact that the steel waist beam is easily stressed locally, a reinforced concrete waist beam template is difficult to process, and a construction period is long. The invention further discloses an assembly type retaining structure connecting method.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering prevention and control, and relates to a connecting device for an assembled retaining structure, and also relates to a connecting method for an assembled retaining structure. Background technique [0002] Anchor-stayed retaining structures are widely used in geotechnical engineering prevention and control fields such as foundation pit support and slope prevention and control. The anchor-pull retaining structure provides a fulcrum reaction force through the anchor rod (cable) that penetrates into the stable rock and soil mass to balance the rock-soil pressure transmitted from the soil retaining member that is set on the side wall of the object to be controlled and embedded in the bottom surface, so as to realize the prevention and control. Object security and stability. The reliability of the connection between the anchor rod (cable) and the retaining member is related to the effe...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an assembly-type support structure connecting device, which solves the problem of the local instability of the steel waist beam that is prone to torsion and overturning due to excessive local force and the problem of the reinforced concrete waist beam existing in the prior art. Formwork processing is difficult and the construction period is long
