Abstract
The utility model provides a presplit blasting baffle, its structure sets up to the cockscomb structure in the little circle of its inner circle for the ring form, presplit blasting baffle's external diameter confirms according to the aperture in big gun hole that the internal diameter is confirmed according to the diameter of explosive fuse. Pass the presplit blasting baffle internal diameter with the explosive fuse during use, through cockscomb structure fixed stop position, spread into into downtheholely with explosive fuse and the little medicated roll of emulsion explosive to make the little medicated roll of emulsion explosive keep away from the side slope pore wall, the reduction explosive forms more smooth side slope face to the katogene of pore wall.
Description
Technical field
The utility model relates to a kind of explosion field, especially relates to a kind of presplit blasting baffle plate.
Background technology
Big gun hole is put into after existing presplit blasting construction usage primacord and emulsion small medicine coil are intertwined and connected, but destroy comparatively serious to hole wall, some construction site uses bamboo chip to solve for improving Slope leveling degree, but effect is undesirable, cost is higher simultaneously, inefficiency.
Utility model content
The utility model want technical solution problem to be: in current presplit blasting engineering, in big gun hole, ignition charge does great damage to hole wall, there is high, the inefficient problem of blasting cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of presplit blasting baffle plate, and its structure is circular, is set to zigzag in its inner ring small circle.
The external diameter of described presplit blasting baffle plate is determined according to the aperture in big gun hole, and internal diameter is determined according to the diameter of primacord, and described presplit blasting baffle plate show that material will select the material that hardness is larger.
Function: during use, primacord is passed presplit blasting baffle plate internal diameter, by zigzag fixed dam position, import in hole with primacord and emulsion small medicine coil, thus make emulsion small medicine coil away from side slope hole wall, reduce explosive to the destruction of hole wall, form more smooth side slope face.
The beneficial effects of the utility model are: emulsion can be avoided directly to contact hole wall, reduce explosive to the impact of hole wall, improve quick-fried rear hole wall flatness, reduce the damage that explosive opposite side is domatic, global blowup effect after raising explosion.
Accompanying drawing illustrates:
Fig. 1 is the structural scheme of mechanism of presplit blasting baffle plate;
Fig. 2 uses presplit blasting baffle plate construction schematic diagram;
In figure: 1, primacord; 2, hole wall; 3, presplit blasting baffle plate; 4, emulsion small medicine coil.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of presplit blasting baffle plate 3, and its structure is concentric ring-shaped structure, is set to zigzag in its inner ring small circle; The external diameter of presplit blasting baffle plate is determined according to the aperture of blasthole hole wall 2, and internal diameter is determined according to the diameter of primacord 1.
During use, primacord 1 is passed presplit blasting baffle plate 3 internal diameter, by zigzag fixed dam position, import in hole wall 2 with primacord and emulsion small medicine coil 4, thus make emulsion small medicine coil 4 away from side slope hole wall 2, reduce explosive to the destruction of hole wall 2, form more smooth side slope face.
