Embodiment Construction

[0034] The present invention will be described in detail below through embodiments according to the present invention in conjunction with the accompanying drawings. For clarity of description, the orientations or positional relationships indicated by "upper", "lower", "left", "right", etc. are based on the orientations or positional relationships shown in the drawings.

[0035] Such as figure 1 As shown, the reduced-sized subway tunnel / train car double narrow space fire experiment platform includes a tunnel unit 1, a train unit 2, a track unit 3, a fire source simulation unit 4, a longitudinal ventilation unit 5, and a fire parameter measurement unit 6.

[0036] Such as figure 2 As shown, in order to save construction costs and facilitate the shooting of experimental phenomena, the cross-sectional shape of the actual tunnel is approximated on the basis of satisfying the equivalent hydraulic diameter and equivalent height. The tunnel is adjusted to be vertical on both sides a...

Abstract

The invention discloses an indent-size subway tunnel / train compartment dual-long and narrow space fire experiment platform. The fire experiment platform comprises a tunnel unit, a train unit, a railway unit, a fire source simulation unit, a longitudinal ventilation unit and a fire parameter measurement unit, wherein the tunnel unit adopts an arc-shaped ceiling structure and is located on the ground; the train unit is placed in the tunnel unit and controlled by the railway unit on the ground to move; the fire source simulation unit is placed in the train unit and used for generating fire plumesrequired by an experiment; the longitudinal ventilation unit is placed at one end of the tunnel unit and used for providing longitudinal ventilation; the fire parameter measurement unit is used for collecting various parameters in the experiment. By means of the fire experiment platform, the defects that a full-size experiment is high in cost, and numerical simulation is not precise enough are overcome, research on a series of basic theories of the entrainment characteristics of the fire plumes, smoke transportation behaviors and the like generated when a train fire occurs in a tunnel can bedeveloped, and the platform has a practical guiding significance for fire detection, smoke control and personnel evacuating in a fire scene.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a reduced-sized subway tunnel / train carriage double narrow space fire experiment platform. Background technique [0002] With the continuous advancement of China's urbanization process, the urban population continues to increase, accompanied by serious road traffic congestion. The subway has the characteristics of a large passenger transport volume and the operating space is mainly underground, which is of great significance for alleviating the increasingly tense urban road traffic pressure. However, while the subway brings convenience to people's life, it also brings new challenges to fire prevention and control. Statistics show that 85% of the deaths in fires are caused by human inhalation of toxic gases, and the accumulated high-temperature smoke may cause secondary disasters such as damage or even collapse of the tunnel structure. [0003] Although according to the requ...
