Description

Tunnel pipe gallery for accommodating large-diameter drainage pipeline and construction method of tunnel pipe gallery Technical Field The invention relates to the technical field of underground engineering, in particular to a tunnel pipe gallery for accommodating a large-diameter water taking and draining pipeline and a construction method thereof. Background For nuclear power plants, the extraction and drainage tunnels often need to be extended to deep sea or specific waters to meet environmental emissions and cooling requirements. This long distance draws water from the sea to the inland power plant for cooling, and then long distance drains the water to the sea. Seawater and radioactive drainage have certain influence on the surrounding environment, so that larger burial depth is also needed, and the construction difficulty is extremely high. Besides, the tunnel pipe gallery of the nuclear power plant has other characteristics. First, a nuclear power plant requires a large amount of seawater for dc cooling, which determines that the diameter of its drainage pipes and culverts is very large. The combination of large burial depth and limited space results in difficulty in ensuring that the pipe gallery structure and the construction method in the related technology can be installed in a narrow space with high efficiency and high quality, and the structure is inconvenient to maintain in the later period and dangerous to construct. Accordingly, there is a need to develop a new tunnel pipe gallery for accommodating a large-diameter drainage pipe and a construction method thereof to improve problems in the related art. Disclosure of Invention The invention aims to provide a tunnel pipe gallery for accommodating a large-diameter water taking and draining pipeline and a construction method thereof, which can be used for efficiently and conveniently performing construction and maintenance.
