Abstract

The invention discloses a taking-out device and a taking-out method for blast hole blockage material. The device comprises a hole digging cylinder and a pushing rod, the hole digging cylinder is of a hollow tubular structure, one end of the hole digging cylinder is provided with a gap, the other end of the hole digging cylinder is connected to a handle, the handle is provided with a through hole, the pushing rod penetrates through the through hole of the handle and the hole digging cylinder, one end of the pushing rod is connected to a piston, the piston is arranged in the hole digging cylinder, and the other end of the pushing rod is connected to a top plate. According to the device, the blockage material in blast holes can be taken out safely and reliably in a time-saving and labor-saving mode.

Description

technical field [0001] The invention belongs to the technical field of engineering blasting, and in particular relates to a device for taking out blockages in blastholes and a method for taking out blockages in blastholes. Background technique [0002] Drilling and blasting is the most commonly used blasting method in blasting engineering, mainly including drilling, charging, plugging, networking and detonation. Among them, the material that blocks the blast hole is mainly a mixture of clay and fine sand. During the construction process, due to factors such as the quality of blasting equipment, personnel errors, and weather, the blast hole failed to blast. It was necessary to remove the blockage in the blast hole, and then recharge, block, and blast. [0003] At present, wooden sticks, PVC pipes, etc. are commonly used by blasters as tools for pulling out blockages in blastholes. Using these tools to dig out blast hole operations is inefficient; meanwhile, according to the...
