Embodiment 1

[0038] like Figure 1-5 As shown, the tunnel collapse rescue comprehensive drill simulation system includes two side walls 4, and the two side walls 4 are concrete structures, specifically, some crushed stones with a particle size of less than 25 cm are mixed into the concrete, and the amount of crushed stones is different. More than 20%, the skeleton of the side wall 4 can be connected and formed by using waste steel bars according to the size of the simulated tunnel side wall, and inserted into DN65 steel pipes to simulate the tunnel foundation. The arc-shaped top cover 3 arranged above the two side walls 4, the arc-shaped top cover 3 is a steel truss structure, and the arc-shaped top cover 3 is safe and effective through the flange plate and the side walls 4. Connection. One side of the channel formed by the two side walls 4 and the arc-shaped top cover 3 is an open structure, and the other side is closed by the back wall 1, and the back wall 1 is a brick structure and on ...

Embodiment 2

[0044]The method of using the tunnel collapse rescue comprehensive drill simulation system includes any of the above-mentioned tunnel collapse rescue comprehensive drill simulation systems, and the usage method is as follows:

[0045] Method 1: Carrying out the drill of the small pilot pit rescue method, specifically, the rescue personnel pass through the small pilot pit mouth 9 during the drill;

[0046] Method 2: Conduct drills of opening up life passages with a horizontal drilling rig, specifically, during the drill, rescuers use a horizontal drilling rig to drill at the mouth 12 of the horizontal drilling rig;

[0047] Method 3: Carry out drills of pipe jacking method, specifically, rescuers conduct the drill through the pipe jacking port 11;

[0048] Method 4: Carry out large-diameter drilling rig method drills, specifically during the drill, rescuers conduct through the mouth 8 of the large-caliber drilling rig;

[0049] Method 5: Carry out the drill of the central drai...

Abstract

The invention discloses a tunnel collapse rescue comprehensive exercise simulation system, the system comprises two side walls, an arc top cover is arranged on the two side walls, one side of a channel formed by the two side walls and the arc top cover has an open structure, the other side is closed by a back wall, and an openable-closable gate is arranged in the back wall; a gravelly soil pile is arranged on the middle part of the channel, the side shape of the gravelly soil pile is an triangle, sand pockets are arranged on front side and the rear side of the gravelly soil pile, a horizontal drilling machine port is arranged on the gravelly soil pile, a clay area is arranged below the horizontal drilling machine port, a top tube port is arranged in the clay area, and a large-caliber drilling machine port, a central drainage pipe and a small heading port are arranged below the clay area. The invention also discloses an application method of the system, and the method comprises the steps: small heading port rescue exercise; horizontal drilling machine breaking through life channel exercise; top tube method exercise; large-caliber drilling machine method exercise; central drainage ditch rescue method exercise; and any combined exercise of the above method.

Description

technical field [0001] The invention relates to a drill simulation system, in particular to a tunnel collapse rescue comprehensive drill simulation system and a use method. Background technique [0002] Tunnels are engineering buildings buried underground, and the construction of tunnels needs to be done underground, so there are many uncertain safety factors in the construction of tunnels. Among them, due to the long length of the tunnel project, complex geological conditions, insufficient depth of investigation, unreasonable construction plan, red line control of the process, and poor execution, the construction process has huge risks, and the "closed door" phenomenon caused by the collapse of the tunnel under construction Occurs from time to time, causing a great threat to the safety of construction workers. When a tunnel collapse disaster occurs, it is particularly important to timely grasp the location, number of people buried, and on-site distribution information for ...
