Embodiment Construction

[0032] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0033] see figure 1 , the main body 1 of the experimental bench 1 of the underground road tunnel fire experiment simulation device that adopts shaft natural smoke exhaust includes a side wall 2 made of fireproof boards, a ceiling, a bottom plate and a side wall 5 made of glass, a shaft 7 is set above the ceiling, and fuel and fire source 4. The main body of the test bench is 6m long, the inner height of the tunnel is 0.88m, and the width is 2m. The height and cross-sectional size of the shaft can be adjusted according to the experimental requirements. The main body of the test bench uses angle steel as a supporting frame. The side walls 5 of the shaft are made of tempered glass.

[0034] see figure 2 , the temperature probe string 8 below the shaft is arranged under the shaft, and the temperature probe string 9 of the right opening of the t...

Abstract

The invention provides an underground highway tunnel fire disaster experiment simulating device adopting a vertical shaft to carry out natural smoke extraction. The device comprises a main experiment table body and a matched measuring and controlling system. The experiment device serves as a small-sized experiment table which is specially used for carrying out comprehensive system researches on heat release rates, smoke movement, fire disaster detection and putting-out and the like in a fire disaster of an underground highway tunnel adopting the vertical shaft to carry out the natural smoke extraction. On the basis of previous experience, the device disclosed by the invention overcomes the defects of high cost of a full-sized experiment and inaccuracy of a numerical value simulating tool, and also guarantees the repeatability of experiments, thus having great application values on implementing a laboratory scientific research and simulating tests of actual tunnel smoke control, vertical shaft smoke extraction effects, and a detection and putting-out system. Therefore, the device disclosed by the invention has wide application prospect and important actual guiding meanings on the smoke control, the design of the detection and putting-out system, and test evaluation and research of the fire disaster of the underground highway tunnel adopting the vertical shaft to carry out the natural smoke extraction.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to a fire experiment simulation device for an underground highway tunnel using a vertical shaft to naturally exhaust smoke, which is used to monitor the flow of smoke and the smoke control system during a fire in an underground highway tunnel using a vertical shaft to naturally exhaust smoke Do a mock test. Background technique [0002] Underground highway tunnels are one of the important ways to solve the increasingly congested traffic problems in cities. At present, Tokyo, Moscow, Beijing, Shanghai and other big cities have built or are building underground highway tunnels. Because urban underground highway tunnels have the characteristics of both underground buildings and highway tunnels, their fire risk is very high. In order to ensure the safety of personnel in case of fire, an effective smoke exhaust system must be installed in the tunnel. In the fire problem...
