Transverse channel and parallel guide railway tunnel experiment device

Abstract

The invention belongs to the technical field of railway tunnel fire safety, and particularly relates to a transverse channel and parallel guide railway tunnel experiment device which comprises a ground, a supporting piece arranged at the top of the ground, a track arranged at the top of the supporting piece, a tunnel arranged at the top of the ground, and an illuminating lamp arranged at the top of the tunnel. A transverse channel is arranged on one side of the tunnel, and a camera is arranged at the top of the transverse channel. Through the use of a frequency conversion fan, the air volume can be adjusted in real time, so that the uniform distribution of the air volume and the speed field in the experiment is effectively controlled, the effect of accurate experiment is achieved, the condition in the experiment tunnel can be observed at any time through the camera, the progress of the experiment is monitored in real time, and through the common starting of the two fans, when the smoke dust is much, the smoke dust in the channel can be quickly dispersed, the personal safety is guaranteed, and the entrance of the transverse channel can be quickly found in an experiment through the cooperative use of a reflective strip and an illuminating lamp.

Description

technical field [0001] The invention belongs to the technical field of fire safety in railway tunnels, and in particular relates to an experimental device for horizontal passages and flat guide railway tunnels. Background technique [0002] It is difficult to deal with a fire in a tunnel, especially in a long tunnel, and the evacuation and rescue work is very difficult. In view of the danger of a fire in a long tunnel, the construction of rescue and evacuation projects such as cross passages and parallel pilot pits is very important. The parallel pilot pit is a tunnel built parallel to the tunnel. In case of fire, personnel can enter the parallel pilot pit through the cross passage and escape against the direction of fresh air. The cross passage and parallel pilot tunnel are connected with the main tunnel to form a complex ventilation with multiple entrances and multiple exits. System, to study the distribution of wind speed at the opening of each open cross passage and the ...
