Pipe gallery construction method

Abstract

The invention relates to a pipe gallery construction method. The pipe gallery construction method includes the steps that ground earthwork is exploded layer by layer in a layering mode from top to bottom by a shallow hole blasting method to be loosened, then the loosened ground earthwork is removed by an excavator, a foundation pit is excavated on the ground, and meanwhile, operations that the bottom wall and the side wall of the foundation pit are repaired by a crushing machine, and broken stone cushion paving, concrete cushion paving, pipe gallery body casting, and earthwork backfilling areconducted at the bottom of the foundation pit from bottom to top are conducted. According to the technical scheme of the pipe gallery construction method, the construction process is simplified, the construction difficulty is lowered, the pipe gallery construction method is especially suitable for stratum structures with a great deal of hard rock buried underground, the use frequency of large construction mechanical equipment is greatly decreased, fuel oil is saved advantageously, and energy consumption and pollution emission are lowered; and meanwhile, according to the pipe gallery construction method, damage to an internal stress structure of the underground soil body is extremely low, construction safety is ensured advantageously, and life safety of constructors is ensured.

Description

technical field [0001] The invention belongs to the technical field of construction of an underground pipe gallery, and in particular relates to a method for constructing a pipe gallery. Background technique [0002] The comprehensive pipe gallery is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. With the rapid development of the country, it has become an irreversible trend to make full use of the underground space and save the above-ground space by building an underground comprehensive pipe gallery. As an arterial project of urban underground facil...

AI Technical Summary

Problems solved by technology

The construction technology of the underground comprehensive pipe gallery is becoming more and more mature, but the original stress balance of the soil is destroyed after the construction of the comprehensive pipe gallery, which leads to local subsidence accidents easily in the soil. However, when the existing underground comprehensive pipe gallery is constructed, a large number of Mechanized equipment excavates earth and rocks. However, at the construction site, it often encounters various geological conditions. When encountering some hard rocks, some large-scale mechanical equipment cannot excavate. The construction is difficult and the construction period is short. Not extended, affecting the construction progress and construction efficiency
