Pipeline arrangement is smooth, standard is beautiful.And the timing automatic water spray heavy curtain spray system of bracket chassis installation is then i.e. using tunnel
Working high pressure water, i.e., be atomized to form high pressure water particulate mist shield tape and prevent dust to external diffusion and with water particle using liquid
Landing；Hydrone evaporation can be made full use of to absorb amount of heat again, droplet rapid vaporization, becomes water vapour, so that tunnel is empty
The humidity increase of gas, temperature are down to less than 28 DEG C；Also just lining concrete is done with good using the continuous diffusion of water mist, evaporation
Maintenance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of multifunctional bearer for high methane constructing tunnel
Device, so that the arrangement of tunnel ventilation pipe is safer and standard, and makes bracket system have multiple functions, so as to be conducive to
Save Tunnel Engineering construction cost.
Technical solution is as follows used by the utility model solves the technical problem：
A kind of Multifunctional transporting rack device for high methane constructing tunnel of the utility model, including positioned at tunnel-liner knot
Tunnel exhaust duct below structure crown section, it is characterized in that：Along tunnel extending direction interval setting pair below the tunnel exhaust duct
It forms the bracket of support, and adjustable hanging system is set between each bracket and tunnel lining structure crown section；The bracket is horizontal
Installed below both sides and put sparge pipe, atomizer is arranged at intervals on sparge pipe.
The beneficial effects of the utility model are, the arrangement of tunnel ventilation pipe is safer and standard, and collection exhaust duct is gone along with sb. to guard him, hole
Interior depositing dust cooling, tunnel lining structure coagulation body maintenance multiple function, not only make simple, simple operation, but also certainly
Body is light and handy, easy for installation；Operation cost is cheap, it can be achieved that curtain is sprayed in automation, and protecting effect is obvious, highly practical.
