Modular prefabricated spliced undercrossing tunnel and splicing structure thereof

Abstract

The invention discloses a modular prefabricated spliced undercrossing tunnel. The modular prefabricated spliced undercrossing tunnel comprises tunnel shallow ship chute sections located at the two ends of the tunnel, a tunnel frame section located at the middle portion of the tunnel, and tunnel deep ship chute sections which are located on the two sides of the tunnel and connect the tunnel frame section with the tunnel shallow ship chute sections. Each tunnel shallow ship chute section comprises a plurality of shallow ship chute section prefabricated side plates which are arranged in the length direction of the tunnel and can be connected into a whole through a cast-in-place bottom plate. Each tunnel deep ship chute section comprises a plurality of deep ship chute section splicing units which are arranged in the length direction of the tunnel and can be connected into a whole through a cast-in-place bottom plate. The tunnel frame section comprises a plurality of frame section splicingunits which are arranged in the length direction of the tunnel and can be connected into a whole through a cast-in-place bottom plate. Through modular design of prefabricated plates of the shallow ship chute sections, the deep ship chute sections and the frame section, the chute sections are constructed and spliced into a whole; and splicing of tunnels which are located in different terrains and are different in length is facilitated, and field rapid splicing construction is achieved.

Description

technical field [0001] The invention relates to the technical field of underground tunnel construction structures, in particular to a modular prefabricated and assembled underpass tunnel and its assembled structure. 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 landscap...

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.
