Embodiment Construction

[0032] In the following, the present invention will be further explained through embodiments with reference to the drawings.

[0033] See figure 1 , The main body 1 of the experiment bench of the underground highway tunnel fire experiment simulation device that adopts the natural smoke exhaust of the vertical shaft includes a side wall 2, a ceiling, a bottom plate, and a side wall 5 formed of glass. A shaft 7 is set above the ceiling, and a fuel is set in the tunnel. And fire source 4. The main body of the experiment platform is 6m long, the inner height of the tunnel is 0.88m, and the width is 2m. The height and cross-sectional dimensions of the shaft can be adjusted according to the experimental requirements. The main body of the test bench uses angle steel as the support frame. The side wall 5 of the shaft is made of toughened glass.

[0034] See figure 2 , A temperature probe string 8 under the shaft is arranged below the shaft, and a temperature probe string 9 for the right...

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 an underground highway tunnel fire experiment simulation device using vertical shaft natural smoke exhaust, which is used for monitoring the flow of smoke and smoke control system of underground highway tunnel fire when using vertical shaft natural smoke exhaust Conduct simulation tests. Background technique [0002] Underground highway tunnels are one of the important ways to solve the increasingly congested traffic problems in cities. At present, metropolises such as Tokyo, Moscow, Beijing and Shanghai have built or are constructing underground road tunnels. As urban underground highway tunnels have the characteristics of both underground construction and highway tunnels, their fire hazard is very high. In order to ensure the safety of personnel during a fire, an effective smoke exhaust system must be installed in the tunnel. In the fire problem of highway tunnels,...
