Abstract

The invention belongs to the technical field of pipe gallery construction, and particularly relates to an underground excavation construction method for underground multi-cabin utility tunnel underpass buildings. A utility tunnel is prefabricated in a factory by adopting segment prefabrication and assembly, a formwork system adopts a customized complete set of steel formwork and vertical pouring,the outer wall of a steel structure outer mold is a steel plate, the interior of the steel structure outer mold is of steel truss structure; the outer wall of a steel structure inner mold of each cabin is a steel plate, and the interior of the steel structure inner mold is of steel truss structure. According to the weight of different segments, different lifting points are adopted, a underground multi-cabin utility tunnel is formed by splicing prefabricated reinforced concrete utility tunnel segments through adhesives and tensioning the prefabricated reinforced concrete pipe gallery sections in a prestress mode, the adhesives play a role in adhesion and achieve the effects of filling, sealing, seepage resistance, leveling and the like. The method has the advantages of being high in stability, high in construction speed and the like, the construction quality can be guaranteed, the safety of existing buildings is guaranteed, and smooth proceeding of follow-up crossing construction is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of pipe gallery construction, and in particular relates to a construction method of underground excavation for an underground multi-cabin pipe gallery passing through a building. Background technique

[0002] The limited space resources make urban development gradually present the basic characteristics of a high concentration of scattered and independent resource elements. While strengthening the efficiency of urban management, it also makes the coverage area much more risky than other areas. The urban underground comprehensive pipe gallery (hereinafter referred to as "pipe gallery") accommodates municipal pipelines such as gas, electricity, and communications, and transports and distributes basic social and economic resource elements. It is known as the "urban pulse" and plays a role in regulating and optimizing cities Underground space, which plays an important role in beautifying the image of the city, is...
