Problems solved by technology

[0002] Typical mountainous cities in my country have narrow roads, traffic jams, dense buildings on both sides, and often no suitable construction sites. It is difficult to arrange auxiliary structures of stations, especially in mountainous cities with insufficient underground space resources. method, and seldom solve the problems faced by the excavation of auxiliary structures, such as large amount of engineering demolition, difficulty in controlling ground subsidence, endangering the safety of structures and surrounding buildings, etc., which brings certain difficulties to the smooth construction of the tunnel project

Embodiment

[0047] Guanshui Road Station is a submerged station of Guiyang Urban Rail Transit Line 2. It is located at the intersection of Baoshan South Road and Guanshui Road in Nanming District, and is arranged in a south-north direction along Baoshan South Road. Guiyang City is a typical mountainous city with narrow roads, traffic congestion, dense buildings on both sides, often no suitable construction sites, and difficulties in laying out auxiliary structures of stations.

[0048] refer to Image 6 , K is the opening of the main structure of the subway car. If the traditional ventilation structure is adopted, the main structure has many openings, the project risk is high, and two buildings need to be demolished, with an area of ​​10719m 2 , the investment cost is 170 million yuan.

[0049] refer to Figure 7 , using the ventilation structure of the present invention, the wind pavilion group and the entrance and exit are combined with the construction site to be uniformly arranged, ...

Abstract

The invention discloses a ventilation structure of a mined metro station in a mountain city and a construction method thereof. The construction demolition area and investment cost are reduced effectively, and the engineering risk of opening on a main structure is reduced. The ventilation structure comprises a metro station and an up-going running tunnel and a down-going running tunnel, and the up-going running tunnel and the down-going running tunnel pass through the metro station longitudinally. An exhaust channel is arranged on the end wall of a station hall, located at one end of the station, of the metro station, and the outer end of the ventilation channel is connected with centrally-arranged ventilation shaft transverse channels to form a fresh air / exhaust channel. The ventilation shaft transverse channels, the up-going running tunnel and the down-going running tunnel and the exhaust channel are arranged in the delta-shaped mode, and fresh air, exhaust air and piston air is vented from the ground through the centrally-arranged ventilation shaft transverse channels and a ventilation shaft.

Description

technical field [0001] The invention relates to a subway station, in particular to a ventilating structure and a construction method for a subway underground excavation station in a mountainous city. Background technique [0002] Typical mountainous cities in my country have narrow roads, traffic jams, dense buildings on both sides, and often no suitable construction sites. It is difficult to arrange auxiliary structures of stations, especially in mountainous cities with insufficient underground space resources. method, rarely solve the problems faced by the excavation of auxiliary structures, such as large amount of engineering demolition, difficulty in controlling ground subsidence, endangering the safety of the structure and surrounding buildings, which brings certain difficulties to the smooth construction of the tunnel project. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ventilation structure for underg...
