Description
Technical Field
The utility model belongs to the engineering blasting field relates to a blast hole mouth prevents that a tunnel blasting from plugging protector with blast hole that the rubble falls into.
Background
Tunnel's the dozen often adopts the explosive blasting technique, all adopts the rig to punch to the massif before the blasting, because of the distance is shorter between each big gun hole, often can be carelessly fill in rubble, mud etc. with next-door neighbour's big gun hole to new big gun hole boring often, leads to the big gun hole degree of depth to be not conform to the requirement, often needs clearance etc. again, consuming time, hard.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provides a simple structure, convenient to use, and the cost is with low costs, portable's a protection device is clogged with big gun hole for tunnel blasting.
In order to realize the utility model discloses an aim, the utility model discloses a realize like this: the utility model provides a protector is clogged with big gun hole in tunnel blasting, is including the cavernosum that is the toper structure, the cavernosum material be the PVA material, cavernosum up end be provided with the mounting, the mounting arrange in the cavernosum just the mounting diameter be less than cavernosum up end diameter, the mounting run through the cavernosum lower extreme through the spliced pole and be provided with the connecting piece, the spliced pole lower extreme be the inside helicitic texture that is provided with of cavity structure, the connecting piece pass through the fix with screw in cavernosum lower extreme, the connecting piece diameter be less than cavernosum lower extreme end diameter, mounting and spliced pole be the integrated into one piece structure, the mounting on be fixed with the handle.
The utility model discloses the beneficial effect who produces is: this use is novel to adopt a material that is the toper structure to be PVA's the cavernosum that absorbs water, the cavernosum upper end is equipped with a mounting, the mounting passes the cavernosum through the spliced pole and fixes through the screw with the connecting piece of cavernosum lower extreme, the spliced pole lower extreme is the cavity structure, inside is equipped with the helicitic texture, can fix through the screw just, mounting and spliced pole be the integrated into one piece structure, still set up a handle on the mounting, and convenient to carry places the device in big gun sky, can absorb the moisture in big gun hole while can be firm fix in big gun drill way, prevent that dirty cement and rubble from getting into, the effectual big gun hole degree of depth of protection has been reached.
Generally, the utility model has the advantages of simple design structure, convenient use, portability, low cost and the like.
