Equipment foundation dismounting-free bolt box construction method

Abstract

The invention relates to an equipment foundation bolt box construction technology, in particular to an equipment foundation dismounting-free bolt box construction method. The problems that a traditional equipment foundation bolt box construction technology is long in construction period, large in construction labor intensity, high in construction cost and poor in construction quality are solved. The equipment foundation dismounting-free bolt box construction method comprises the following steps that a, a dismounting-free bolt box is prefabricated, wherein firstly, a square-barrel-shaped steel framework is formed by welding steel bars, the square-barrel-shaped steel framework is formed by welding the vertical steel bars and a plurality of square hoops in a vertical crossing mode, each square hoop is formed by welding four cross steel bars end to end, the outer side face of the square-barrel-shaped steel framework is wrapped by a fine-mesh screen mesh, and the fine-mesh screen mesh and the square-barrel-shaped steel framework are bound and fixed through binding wires; b, the dismounting-free bolt box is mounted; c, concrete is poured; d, the dismounting-free bolt box is protected. The equipment foundation dismounting-free bolt box construction method is suitable for construction of large equipment foundation bolt holes and preserved holes.

Description

technical field [0001] The invention relates to the construction technology of the bolt box of the equipment foundation, in particular to a construction method of the equipment foundation without dismantling the bolt box. Background technique [0002] The traditional equipment foundation bolt box construction is mainly realized through wooden bolt boxes. Practice has shown that the traditional equipment foundation bolt box construction technology has the following problems due to its own principle limitations: First, when prefabricating wooden bolt boxes, a large amount of wood needs to be consumed, which leads to high construction costs. Second, when pouring concrete, because the wooden bolt box cannot be fixed with the steel mesh of the equipment foundation, the wooden bolt box is prone to offset under the extrusion of concrete, resulting in poor construction quality. Third, after the pouring of concrete is completed, not only does it take a lot of time and manpower to di...
