Construction method of hoisting reinforcement cage with walls combined with stress gauge

Abstract

The invention relates to the technical field of reinforcement cages, and discloses a hoisting construction method of a diaphragm wall reinforcement cage combined with a stress detector. The hoisting construction method involves a reinforcement cage, a main crane, an auxiliary crane, the reinforcement stress detector and background detecting and reading equipment. The reinforcement stress detectoris mounted on the reinforcement cage and electrically connected with the background detecting and reading equipment. Before the reinforcement cage is hoisted, a hoisting point is set firstly, a largedeformation position in the reinforcement cage hoisting process is found, the stress value of the large deformation position is calculated, and 90% of the stress value is adopted as an early warning value. Before hoisting is carried out, the reinforcement cage is firstly machined into the diaphragm wall reinforcement cage, and the reinforcement stress detector is mounted at the large deformation position and electrically connected with the background detecting and reading equipment; in the hoisting process, reinforcement stress displayed by the background detecting and reading equipment needsclose observation, the hoisting speed of the main crane and the auxiliary crane is adjusted in time before the early warning value is reached, so that the deformation of the reinforcement cage is reduced; and therefore reinforcement cage breaking caused by the too large deformation of the reinforcement cage is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of reinforcement cages, in particular to a construction method for hoisting reinforcement cages connected to walls combined with stress gauges. Background technique [0002] For the hoisting construction of super-long and super-heavy underground diaphragm wall reinforcement cages, the construction methods of overall production, double-machine overall hoisting, overall straightening in the air, and one-time entry into the groove are often used. [0003] However, in the implementation process, the crane is used to direct the lifting of the steel cage through human observation, so observation errors often occur, resulting in excessive deformation of the steel cage, and even the collapse of the steel cage, causing great losses to the project.

Problems solved by technology

[0004] The object of the present invention is to provide a construction method for hoisting steel cages connected to walls combined with stress gauges, aiming to solve the problem that in the prior art, it is difficult to find the deformation of the steel cages by directing the hoisting of the cranes through human visual observation, which may easily lead to the deformation of the steel cages. The problem that the deformation is too large and the steel cage falls apart
