Abstract

The invention discloses a single-hole dual-line jet fan tunnel section designed based on the municipal administrative area D-type vehicle limit. The tunnel section is composed of eight arcs in total.A tunnel is a single-hole tunnel and is internally provided with dual-line rails, and a middle partition wall is arranged in the middle. An evacuating platform and jet fans are arranged on the two sides of the middle partition wall. The two jet fans on the left side and the right side at the same height are longitudinally staggered. A rail structure and a municipal administrative area D-type vehicle are sequentially arranged in the tunnel from bottom to top. By means of the scheme, the requirements of vehicle limit, building limit, structure layout, equipment installation, personnel evacuatingand other aspects are sufficiently considered, the requirement for driving safety of a train is met, the interference of the train with buildings and equipment is avoided, it is reasonably and effectively ensured that the vehicle cannot exceed the limit in the driving process, the area of the tunnel section is reduced, and the engineering investment is reduced.

Description

technical field [0001] The invention belongs to the field of urban railway tunnels, and in particular relates to a single-hole double-line jet fan tunnel section structure based on the boundary design of urban D-type vehicles. Background technique [0002] The jet fan is a special axial flow fan, which is mainly used in the longitudinal ventilation system of tunnels such as roads, railways and subways to provide full thrust, and can also be used in sensitive parts of semi-transverse ventilation systems, such as the entrance and exit of tunnels , Play the role of inducing air flow or exhausting smoke. [0003] The installation position of the jet fan is generally at the top wall of the tunnel. Usually, a high-power fan is installed in an air duct to drive the air to form a jet, so as to achieve the purpose of air exchange and circulation in the tunnel. [0004] Urban railways connect metropolises and satellite cities, and are defined as between urban rail transit and high-sp...
