Abstract

The invention discloses a parallel double-island type tunnel construction method which comprises the following steps that a vertical shaft is built at a first preset position on the ground, and after the vertical shaft is built, a horizontal air duct is built at the bottom of the vertical shaft towards a second preset position in the first preset construction direction; along with construction of the horizontal air duct, a first tunnel and a second tunnel which are spaced from each other are sequentially built in the formed horizontal air duct in the second preset direction, and in the construction process of the first tunnel and the second tunnel, connecting channels are arranged at preset intervals in the second preset construction direction, and the connecting channel is used for communicating the first tunnel with the second tunnel. According to the construction method, synchronous construction of the two tunnels can be conveniently achieved, the construction efficiency is improved, and safe and rapid construction of the double-island type station tunnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a parallel double island tunnel construction method. Background technique [0002] The subway is a fast, large-capacity, electric-driven rail transit built in the city. Trains run on fully enclosed lines. Lines located in the central urban area are basically located in underground tunnels, and lines outside the central urban area are generally located on viaducts or on the ground. In English, metro (underground railway, subway). The subway is an urban rail transit system (Metro) with exclusive right of way, high density and high traffic volume covering various underground and above ground in urban areas. [0003] With the acceleration of urbanization in my country, the number and mileage of subway lines in some cities in my country have exploded. Due to the consideration of subsequent additional lines in the early construction of some lines, the design of some subw...
