Problems solved by technology

On the one hand, the subway train itself will also have a significant impact on the flow behavior of the smoke at the key junction of the tunnel track area and the platform, and even the smoke control flow field of the entire subway station; At the combination site, after setting up the smoke-blocking vertical wall in the event of a fire on the platform, due to its barrier effect on the smoke, the smoke distribution on the platform floor and the station hall floor will have a cert

Embodiment Construction

[0040] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0041] see figure 1 , the main body of the simulation experiment platform for fire and smoke control at key joint parts of the subway station includes the simulated station hall floor 1, the simulated platform floor 2, and the simulated tunnel track area 3. The floor of the simulated station hall is 2m long, 1.2m wide, and the internal height is 0.44m; the simulated platform area is 8m long, 1.2m wide, and 0.44m high; the simulated tunnel track area is 12m long, 0.5m wide, and 0.6m high. The main body of the test platform adopts a steel frame structure and is located on the support base 4. The platform floor is 0.75m from the ground, and the tunnel track area is 0.6m from the ground. Twelve side doors 5 are installed on the steel frame on the outer side of the tunnel track area, and eight side doors 6 are also installed on the steel frame struc...

Abstract

The invention provides an experiment platform for simulation of control over fire smoke at key connection positions of a subway station. The experiment platform for simulation of control over the fire smoke at the key connection positions of the subway station comprises a simulated station hall layer, a simulated platform layer, a simulated tunnel rail traveling layer, a simulated subway train, a ventilation and smoke discharge system, an air curtain system and a fire parameter measurement system. By the adoption of the experiment platform, study on a series of basic theories such as the flowing characteristics of fire smoke, generated when a fire disaster occurs on a subway station, at the key positions where a platform, a station hall and a tunnel rail traveling area are connected and control mode optimization and engineering practical problems can be conducted; a complete solution to study on the evolvement rule of the characteristic parameters such as the effectiveness of a technology for controlling the fire smoke at the key connection positions of the subway station, the temperature field and the poisonous gas concentration field in the scene that fire disaster occur on subway train fire-prevention parking stations and a subway station platforms is provided.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to the flow characteristics and flue gas flow characteristics of fire smoke in the key joint parts of the tunnel track area, platform and station hall under various fire scenarios such as train fire stop station and subway station platform fire. The simulation experiment platform for testing the optimization of the control mode can comprehensively realize the smoke exhaust system (Over Tunnel Exhaust, OTE) in the tunnel track area, the smoke exhaust system (Under Tunnel Exhaust, UPE) in the tunnel track area, and the tunnel fan system ( Tunnel Ventilation Fan, TVF), platform air supply and exhaust system, station hall air supply and exhaust system, air curtain system, smoke barrier and vertical wall smoke barrier, etc. Different combination modes and parameter adjustments of various smoke control systems; can realize temperature field, Measurement of key parameters suc...
