Problems solved by technology

The structure in which the interval tunnel ventilation system 100 and the station tunnel ventilation system 200 are independently installed is not only expensive for civil engineering, but also occupies a large area of ​​ground, making land acquisition and demolition difficult.
Due to the large number of fans used, the station needs a large area as the machine room area, and the power distribution investment is large and the control is complicated

Embodiment Construction

[0027] Such as figure 2 As shown, a new tunnel ventilation system of a subway station is used to ventilate the section tunnel and the station tunnel. By combining the station tunnel and the section tunnel ventilation system 100, the tunnel ventilation system greatly reduces the number of piston air shafts and The number of tunnel fans reduces the area occupied by the station and the construction cost, and reduces the operating cost and energy consumption of the ventilation system.

[0028]This tunnel ventilation system comprises the first air shaft 141 and the second air shaft 241 respectively arranged at the two ends of the station, the first piston air shaft 151 and the second piston air shaft 251, which communicate with the first air shaft 141, the station tunnel and The first row of air ducts 171 in the platform hall, the first connecting air duct 176 connecting the first row of air ducts 171 and the downlink tunnel 400, the first piston air duct 172 connecting the first ...

Abstract

The invention relates to a novel tunnel ventilation system for a subway station, which is applied to ventilation of an inter-region tunnel and a station tunnel. The novel tunnel ventilation system is characterized by comprising first and second exhaust shafts, first and second piston air shafts, a first exhaust passage, a first communication air duct, a first piston air duct, a second exhaust passage, a second communication air duct, a second air duct, first and second upper air ducts, and first and second lower air ducts, wherein a first tunnel blower is arranged on the first exhaust passage or the first piston air duct, a second tunnel blower is arranged on the second exhaust passage or the second piston air duct, and electric blast gates are arranged on the individual air ducts. The ventilation system incorporates the inter-region tunnel ventilation system and the station tunnel ventilation system and reduces the number of station piston air shafts, so as to not only reduce the civil engineering cost but also reduce the floor area occupied.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a tunnel ventilation system of a subway station. Background technique [0002] In recent years, domestic rail transit construction has developed vigorously, and safety, energy saving, and environmental protection have become the goals of rail transit construction. As an important electromechanical system of urban rail transit, the ventilation and air conditioning system occupies about 50% of the area of ​​the station equipment management room and consumes about 1 / 3 of the energy consumption of subway operation. The system scheme of ventilation and air-conditioning system is of great significance to reduce civil construction investment and save energy consumption in operation. [0003] At present, most of the domestic urban rail transit subway stations are equipped with screen doors. The screen door system separates the platform waiting area from the driving tunnel, which not only ensures ...
