Problems solved by technology

[0002] In recent years, China's economy has developed by leaps and bounds, and the appearance of the city has undergone earth-shaking changes. There are many high-rise buildings on the ground and a lot of traffic, but the construction of underground projects is seriously lagging behind. Corridors are generally prefabricated in advance and then assembled on site, so the quality of the prefabricated parts is particularly critical

Abstract

The invention discloses a method for improving positioning qualification rate of pipe gallery embedded parts, and belongs to the technical field of utility tunnel production. According to the method,the defects of traditional embedment construction are overcome, the embedded parts are fully attached to a template to ensure the positioning accuracy of the components, and then the embedded components are welded on the pipe gallery engineering wall steel bars while the vertical dies are vertical, so that the position precision of the embedded parts is guaranteed, the positioning qualification rate of the embedded parts is improved, the prefabricated efficiency is improved, the construction cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery production, and in particular relates to a method for improving the qualified rate of positioning of embedded parts of a pipe gallery. Background technique [0002] In recent years, China's economy has developed by leaps and bounds, and the appearance of the city has undergone earth-shaking changes. There are many high-rise buildings on the ground and a lot of traffic, but the construction of underground projects is seriously lagging behind. Corridors are generally prefabricated in advance and then assembled on site, so the quality of the prefabricated parts is particularly critical. In order to facilitate the fixed installation of the embedded parts, the embedded parts are usually fixed on the steel cage first, but due to the impact force and pressure during pouring It will cause the embedded parts to shift slightly, protrude, sag, and tilt, resulting in poor molding effect of ...
