Abstract

The invention relates to the technical field of underground construction and provides a tunnel-type comprehensive pipe gallery block-type component assembling method. According to the tunnel-type comprehensive pipe gallery block-type component assembling method, a tunnel-type pipe gallery is designed and constructed innovatively through a block prefabricated assembling mode, a set of assembling construction technology is formed, the problems of construction of a large number of cast-in-situ concrete structures in the limited space of the type of engineering are solved, and the construction period is greatly saved; and a large amount of steel bars are innovatively pre-embedded on the inner side of a tunnel secondary lining and a cast-in-place concrete structure of a bottom plate, and the pre-embedding fixing technology that a reinforcement cage is arranged and a square steel pipe rack is reinforced is adopted, so that construction is convenient and fast, and pre-embedded precision is high.

Description

technical field [0001] The invention belongs to the technical field of underground construction, in particular to a method for assembling segmented components of a tunnel-type comprehensive utility gallery. Background technique [0002] The Shiyan City Underground Comprehensive Pipe Gallery PPP project is the first batch of comprehensive pipe gallery pilot projects in the country. For the first time in this project, the integrated pipe gallery and the tunnel structure are combined for design and construction. The maximum length of the tunnel is 505 meters, and the total length is about 1.6 kilometers. This project has the problem of secondary construction of a large number of reinforced concrete in a confined space. The in-depth design of the tunnel-type comprehensive pipe gallery and the selection of construction technology directly affect the performance of various indicators such as the construction period, cost, quality, and safety of the project. [0003] The common ...
