Prefabricated assembled tunnel and construction method thereof

Abstract

The invention relates to a prefabricated assembled tunnel and a construction method thereof. The tunnel comprises a plurality of prefabricated plates. Each prefabricated plate comprises upper cover plates and vertical supporting plates, wherein a segment bin is defined by at least two vertical supporting plates and at least one upper cover plate. In one segment bin, a bottom plate is arranged between the lower end portions of two adjacent vertical supporting plates. In one segment bin, the upper ends of the vertical supporting plates support the upper cover plates, and vertical fastening pieces are connected between the upper cover plates and the vertical supporting plates. The multiple segment bins are spliced into the tunnel in the longitudinal direction, and longitudinal fastening pieces are connected between two adjacent segment bins. Compared with an existing open cutting cast-in-place construction manner, the construction quality can be optimized, and the advantages that the construction period is short, and influences on the environment are weak are achieved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a prefabricated assembly tunnel and a construction method thereof. Background technique [0002] With the development of the economy, the number of urban vehicles is increasing explosively. In a certain period of time and in a certain area, the existing traffic environment network cannot meet the needs of urban development, resulting in traffic congestion. In order to solve this problem, more and more three-dimensional traffic forms are adopted on the nodes of urban arterial roads, and the space of different levels of the city is rationally used, and viaducts or tunnels under the city are set up more. Compared with viaducts or other methods, underpass tunnels have the advantages of undisturbed motor vehicles, fast passage, the ground retains the original function of traffic transformation, and less impact on surrounding landscapes. In recent years, it has gradually increased in...

AI Technical Summary

Problems solved by technology

The traditional construction method of underground tunnels in cities is mainly open-cut and cast-in-place construction. Foundation pit support and water-proof curtains are usually set up for open-cut construction. A lot of garbage, large carbon emissions, great impact on residents and buildings, the quality of cast-in-place concrete in the tunnel structure under the tunnel cannot be guaranteed, and the overall construction cost is high.
