Deep hole reinforcement cage hoisting I-shaped steel auxiliary support construction method

Abstract

The invention discloses a deep hole reinforcement cage hoisting I-shaped steel auxiliary support construction method. During implementation; after the reinforcement cage is manufactured in sections, reinforcing stirrups are welded at proper positions of the reinforcement cage, and after the reinforcement cage is put down, the reinforcement cage is hung at the position of a construction orifice by using I-shaped steel and the reinforcing stirrups, so that the operation is simple, time-saving and labor-saving; the method is suitable for hoisting construction of various deep hole pile foundation reinforcement cages. The construction method has the engineering characteristics of small material investment, no need of processing and manufacturing, convenience in recycling, reusability, high construction efficiency, cost saving and the like. Compared with a traditional clamp, the construction method only uses I-shaped steel and reinforcing stirrups welded to the upper portion of the reinforcement cage as a reinforcement cage bearing system, operation is easy in the construction process, and recovery is convenient after construction is completed.

Description

technical field [0001] The invention relates to the field related to the hoisting and construction of pile foundation reinforcement cages, in particular to a construction method for hoisting I-beam auxiliary support for deep-hole reinforcement cages. Background technique [0002] With the rapid development of highways in my country, the construction of super-long pile foundations has become the norm, and various achievements have been made in the hoisting and construction technology of super-long steel cages. At present, during the hoisting and construction of super-long pile foundation steel cages, due to the long length and heavy weight of the steel cages, the existing equipment cannot be hoisted at one time, and after the steel cages are lowered to the bottom of the holes, due to the large quality of the steel cages, the steel cages cannot be hoisted. There is a risk of back-bending deformation in the closing part of the bottom, which will inevitably affect the constructi...
