[0002] The subway is a rapid, high-capacity, electrically powered rail transit built in cities. The train runs on a fully enclosed line. The line in the central city is basically located in an underground tunnel, and the line outside the central city is generally located on a viaduct or on the ground; the subway is an urban rail transit system that covers various underground and above-ground exclusive rights of way, high density, and high capacity in urban areas. With the development of society, the increase in urban population and the expansion of urban scale, more and more cities have built subways. However, during the construction of the subway main body, it is necessary to excavate entrances and exits in densely populated places such as the city center. Therefore, during the construction process, an enclosing structure is required to isolate the construction site from the surrounding area to prevent accidental injuries caused by unauthorized personnel entering the site during the construction process.
