Separating-type underground excavated double-deck metro station

Abstract

The invention provides a separating-type underground excavated double-deck metro station, and relates to the technical field of metro stations. Equipment areas are arranged at the two ends of both a first underground excavated double-deck tunnel and a second underground excavated double-deck tunnel; the first underground excavated double-deck tunnel communicates with the second underground excavated double-deck tunnel through a communicating channel, and entrance and exit passageways are arranged on the outer sides of the upper part of both the first underground excavated double-deck tunnel and the second underground excavated double-deck tunnel; the inner parts of both the first underground excavated double-deck tunnel and the second underground excavated double-deck tunnel are divided into and arranged as double-deck spaces through center spacers; the upper space of each double-deck space is provided with a station hall, a platform and an escalator, and the lower space of each double-deck space is provided with a heat discharging air duct; and a first line is arranged on one side of the heat discharging air duct in the first underground excavated double-deck tunnel, and a secondline is arranged on one side of the heat discharging air duct in the second underground excavated double-deck tunnel. According to the separating-type underground excavated double-deck metro station,the function of a station craft box can be effectively met, meanwhile, an underground excavated section is reduced, the construction risk is reduced, moving and changing of pipelines can be reduced, traffic reconciliation is optimized, and practicability is higher.

Description

technical field [0001] The invention relates to the technical field of subway stations, in particular to a separate underground excavated double-deck subway station. Background technique [0002] In urban dense built-up areas, there are many ground and underground structures and pipelines, and the traffic on the road is heavy. Commonly used subway construction, such as the use of open-cut method and combination of light and dark stations, is difficult to implement, and there are construction problems such as uncontrollable construction period and high early-stage engineering costs. At the same time, large The full-underground double-deck station of the section has high requirements on geological conditions and high construction risks. Therefore, a new station form and construction method is needed to adapt to the construction of subways in urban dense built-up areas. Contents of the invention [0003] The object of the present invention is to aim at the defects and defici...
