Manual hole digging pile blasting protection device

Abstract

The invention discloses a manual hole digging pile blasting protection device. The blasting protection device comprises a shell, a first protective layer and a second protective layer; the first protective layer and the second protective layer are located on the outer side of the shell; the second protection layer is located under the first protection layer; sliding grooves are formed in the outer walls of the two sides of the shell separately and are symmetric; two first moving blocks are fixedly arranged on the inner walls of the two sides of the first protective layer separately, and two second moving blocks are fixedly arranged on the inner walls of the two sides of the second protective layer separately; threaded holes are formed in the first moving blocks and the second moving blocks; and a first motor and a second motor are fixedly arranged at the top of the shell. According to the blasting protection device, the protection layers are combined with the shell structure so that the safety protection of constructors can be effectively improved, and the amount of blasting residues in a hole and around the hole can be decreased, meanwhile, a certain protection effect can be achieved on the protective walls, and the construction cost can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a blasting protection device for manual hole-digging piles. Background technique [0002] At present, the construction of artificial excavation piles in my country adopts the blasting method. Due to the destructive force and impact caused by the blasting, the gravel will have a destructive effect on the retaining wall, and if the gravel is shot out of the hole, it will also have a certain impact on the safety of the operator. , there is a lot of residue around the orifice and the hole after blasting, and the cleaning cost of the blasting residue is high. In order to realize the rapid and effective transportation of the residue, we propose a blasting protection device for manual digging piles. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of artificial excavation pile blasting pro...
