In a first aspect, the embodiment of the application discloses a protection and alarm comprehensive device for tunnel construction supervision personnel. In order to facilitate the transportation of materials in the tunnel, a transportation rail is paved in the tunnel, and a rail car 1 is arranged on the transportation rail. Referring to fig. 1, the early warning device is installed on the outer side wall of a rail car 1 in a tunnel, and is used for performing reciprocating scanning type monitoring on methane concentration and higher temperature along the rail along with the movement of the rail car 1.

Methane is generally accumulated at the top of the tunnel after it has appeared more because of its lighter molecular mass. Under the action of the driving fan 25, the gas inlet pipe 23 extending to the top of the tunnel sucks the gas at the position of the maximum concentration in the tunnel into the inner cavity of the equipment housing 21, and then the methane concentration detector 22 can detect the methane concentration in the equipment housing 21.
The alarm mechanism 3 comprises a flashing lamp and a warning sound, and when the methane concentration in the inner cavity of the equipment shell 21 reaches a dangerous value which is easy to explode, the flashing lamp and the warning sound can warn surrounding constructors, and constructors in the warning are far away from dangerous positions.
Meanwhile, the early warning equipment can carry out frequent reciprocating monitoring in the tunnel along with the railway vehicle 1, and then the accumulated methane is processed by professional constructors, so that the condition of excessive accumulation of methane in the tunnel is reduced, and the risk of construction in the tunnel is reduced as much as possible.
