Underground comprehensive pipe gallery structure deeply buried in soft soil and construction method of underground comprehensive pipe gallery structure

Abstract

The invention provides an underground comprehensive pipe gallery structure deeply buried in soft soil and a construction method of the underground comprehensive pipe gallery structure. The undergroundcomprehensive pipe gallery structure is a reinforced concrete box type structure with underground diaphragm walls buried in deep and thick soft soil 10 m below as side walls, hidden beams, top beamsand steel bar connectors are arranged on the underground diaphragm walls to be connected with a bottom plate and a top plate of a pipe gallery, and lining walls arranged in the underground diaphragm walls and the underground diaphragm walls are combined to be used as the side walls of the comprehensive pipe gallery. The elevation of the wall tops of the underground diaphragm walls is the same as that of the bottom of the top plate of the underground comprehensive pipe gallery, load-bearing bars of the top plate and wall top anchoring bars of the underground diaphragm walls are connected through the top beams, and the top plate of the comprehensive pipe gallery is formed. The hidden beams are arranged on the portions, corresponding to the bottom plate of the comprehensive pipe gallery, of the underground diaphragm walls and are connected through the steel bar connectors, and the bottom plate of the comprehensive pipe gallery is formed. According to the underground comprehensive pipe gallery structure, the problem that differential settlement is prone to being generated when the underground comprehensive pipe gallery passes through the deep and thick soft soil is solved, the foundation pit support cost is reduced, the construction process of the structure is simple, convenient and fast, and the structure is economical and reasonable.

Description

technical field [0001] The invention relates to the technical field of underground comprehensive pipe gallery engineering, in particular to an underground comprehensive pipe gallery structure buried deep in soft soil and a construction method thereof. Background technique [0002] With the continuous progress of society, underground comprehensive utility corridors have flourished all over the country. The underground comprehensive pipe gallery used for laying various urban pipe networks, its bottom plate is generally buried within 10m underground, and the structure of the comprehensive pipe gallery is a porous reinforced concrete box culvert. The common construction method is to carry out foundation pit support within 10m first , and then excavate the earthwork to the bottom of the comprehensive pipe gallery, and then carry out cushion and reinforced concrete structure construction until the underground comprehensive pipe gallery is completed. However, for the "underground ...

AI Technical Summary

Problems solved by technology

However, for the "underground comprehensive pipe gallery in deep soft soil where the depth of the bottom plate is more than 10m", according to the conventional construction method, the foundation pit support is carried out first, and then the structural construction is carried out. Since the underground diaphragm wall is required in deep soft soil Or pile rows for ultra-deep foundation pit support, the cost is high, the construction is difficult, the construction period is long, and at the same time, it is limited by the narrow site, and the conventional method cannot be implemented

There is no economic advantage in using tunnel shield method or pipe jacking method
