Supervision Outline of Civil Engineering of a Metro Station
1.2.3.3 Architectural layout of the station 1) The underground floor of the station is the hall floor. The station hall floor is divided into three areas from east to west: the west end station hall floor management and equipment room area, the central station hall floor public area, and the east end station hall floor equipment room area. The planned underpass lane divides the west terminal station hall into two parts. The west side is mainly arranged with the environment control electric control room, the environment control room and the communication room. The east side is mainly arranged with the station control room, the communication signal and management room. The two parts are connected through the external underpass channel. The public area of the station hall floor is divided into two areas: the non payment area and the payment area. The two areas are separated by railings, entrance and exit gates and ticket offices. Non payment areas are equipped with automatic vending machines, ticket checkers, vending machines, public telephones, etc. There are two groups of escalators in the pay area to contact the public area of the platform floor. There is a public area for the disabled and staff to contact the platform floor in the pay area. At the south end, the environmental control room, station spare parts warehouse, station tunnel, new air shaft, exhaust shaft and other main equipment rooms are arranged. 2) The second underground floor of the station on the platform floor is the platform floor. The platform floor is divided into three areas from west to east: equipment room area on the west platform floor, public area on the middle platform floor, and equipment room area on the east platform floor. The 100m effective platform is arranged in the middle of the station, and the width of the platform is 12m. The equipment room area on the platform floor at the west end is mainly arranged with step-down substation room, battery room, small air conditioning room, sewage pump room, piston air duct, etc., while the equipment room on the platform floor at the east end is mainly arranged with wastewater pump room, etc. 3) In line with the landscape requirements of the urban planning, the entrance and exit of the entrance and exit passageway should be set in a centralized and small size. The two exits should be set directly and eye-catching on the intersection road, which can maximize the passenger flow and reduce the traffic pressure on the urban road surface. At the same time, we should consider planting beside the entrance and exit to coordinate with the urban landscape.
