Abstract

The invention discloses a tunnel fire experiment simulating device with different smoke exhausting modes and an adjustable gradient. The tunnel fire experiment simulating device comprises a first sub-tunnel, a second sub-tunnel, a telescopic flame-retardant sleeve, a plurality of hydraulic lifting columns, a first variable-frequency motor, a motor elevating bracket, a second variable-frequency motor, a third variable-frequency motor, a smoke exhaust channel, a plurality of smoke collecting covers, a fire source simulating assembly, a matched measuring and controlling assembly, a flow field monitoring field and an image acquisition device. The tunnel fire experiment simulating device can research fire combustion conditions in the tunnels with different gradients in a longitudinal smoke exhausting mode and a concentrated smoke exhausting mode in a laboratory, and realizes observation to a flue gas distribution condition and a fire rule in the tunnel.

Description

Technical field [0001] The present invention relates to the technical field of fire safety, in particular to a tunnel fire experiment simulation device with adjustable slope adopting different smoke exhaust modes. Background technique [0002] As of the end of 2017, there were 16,229 road tunnels nationwide with a total length of 15,285,100 meters, an increase of 1,048, with a total of 1,245,400 meters, including 902 extra-long tunnels with a total of 4.0132,000 meters, and 3841 long tunnels with a total of 6,599,300 meters. China has become the country with the largest, most numerous and most difficult tunnel construction projects in the world. Restricted by the actual engineering geological conditions, many tunnels have a certain longitudinal slope. A study by the United Nations Economic and Social Council (Economic and Social Council) pointed out that in tunnels with a longitudinal slope of 2.5%, accidents such as fires and anchors may occur. The probability is 5 times that o...
