Abstract
The utility model relates to a tunnel blast construction week lateral opening charging means for the subterranean tunnel engineering. The utility model discloses a gasket that is used for the fixed medicated roll's of block mounting groove, and the mounting groove outer wall is equipped with arc. the utility model discloses during implementation, fixing medicated roll in the mounting groove according to the spacing distance block of design earlier, and then connecting the explosive fuse, the big gun hole is gone into in the final assembly. The mounting groove still can set up the length scale, confirms powder charge spacing distance quantification, effectively improves the powder charge precision. In addition, because fixed with the medicated roll block in advance, can effectively improve loading rate, explosive materials such as not fragile explosive and explosive fuse simultaneously, and set up convex gasket and can make medicated roll be in big gun hole centre position, improve the powder charge quality.
Description
Technical field
This utility model relates to a kind of tunnel blasting construction periphery hole means for loading, for subterranean tunnel engineering.
Background technology
Photoface exploision is profile Controlled blasting technique conventional in subterranean tunnel engineering construction.Periphery hole boring and powder charge directly determine tunnel Smooth Blasting Construction effect, affect tunnel construction phase stability and security.During tunnel blasting construction, periphery hole powder charge is usually after completing boring, is tied up by explosive cartridge on bamboo chip, connects primacord etc., is then placed in big gun hole.But, periphery hole uses Uncoincided charge, field operation personnel quantification can not to determine powder charge spacing distance mostly, only with individual subjective judgment depending on, axial Uncoincided charge does not reaches design requirement；Meanwhile, the mode of bamboo chip colligation explosive, often make explosive be placed on bottom big gun hole, it is impossible to being placed centrally in big gun hole, radially Uncoincided charge does not reaches design requirement, affects demolition effect.Additionally, on-the-spot bamboo chip colligation complex procedures, it is easily damaged the explosive such as explosive and primacord, affects engineering construction quality and progress.
Utility model content
Technical problem to be solved in the utility model is: provides a kind of tunnel blasting construction periphery hole means for loading, can be effectively improved loading rate and charging quality.
Be the technical scheme is that tunnel blasting construction periphery hole means for loading by solving above-mentioned technical problem this utility model, including the mounting groove for the powder stick that is fixed, mounting groove outer wall is provided with the pad of circular arc.
Further: pad quantity is more than one piece, arrange along mounting groove length direction uniform intervals.
Further: pad quantity is 2, mounting groove length direction two ends it are located at.
Further: mounting groove section is circular arc.
Further: mounting groove section is semicircle.
Further: mounting groove surface has length scales.
Further: length scales is located at mounting groove inner surface.
Further: the material of mounting groove is plastics.
The beneficial effects of the utility model are: during enforcement, are first fixed in mounting groove according to the spacing distance of design by powder stick, then reconnect primacord, be finally fitted into big gun hole.Owing to mounting groove is provided with length scales, powder charge spacing distance quantification can be determined, be effectively improved charging accuracy.Further, since be fixed by powder stick the most in advance, loading rate can be effectively improved, be hardly damaged the explosive such as explosive and primacord simultaneously, and circular arc pad is set powder stick can be made to be in big gun hole center position, improve charging quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is enforcement schematic diagram of the present utility model；
Labelling in figure: 1-mounting groove, 2-powder stick, 3-big gun hole, 4-multiple-row blasting section, 5-primacord, 6-pad.
Detailed description of the invention
For ease of understanding and implementing this utility model, select preferred embodiment of the present utility model to combine accompanying drawing and be described further.
As it is shown in figure 1, this utility model includes that the mounting groove 1 for the powder stick that is fixed, mounting groove 1 outer wall are provided with the pad 6 of circular arc.
During as in figure 2 it is shown, implement, first powder stick 2 is fixed in mounting groove 1 according to the spacing distance of design, then reconnects primacord 5, be finally fitted into big gun hole 3.Owing to being fixed by powder stick 2 the most in advance, loading rate can be effectively improved, be hardly damaged the explosive such as explosive and primacord simultaneously, and circular arc pad 6 is set powder stick can be made to be in big gun hole center position, improve charging quality.
Pad 6 can be 1, is arranged in the middle part of mounting groove 1, and now pad 6 should have enough length on mounting groove 1 length direction；Pad 6 is preferably arranged to more than one piece, arranges along mounting groove 1 length direction uniform intervals.This utility model also provides for another kind of preferred implementation: pad 6 quantity is 2, is located at mounting groove 1 length direction two ends.
Mounting groove 1 section is preferably circular arc, and its internal diameter is suitable with powder stick 2 diameter.Mounting groove 1 section is the most semicircle, can be while powder stick 2 convenient for assembly, and be effectively fixed powder stick 2, it addition, be also convenient for batch production.
Preferably, mounting groove 1 surface has length scales, determines powder charge interval quantification, can be effectively improved charging accuracy.Length scales is preferably disposed to mounting groove 1 inner surface, and powder charge is spaced to facilitate observation to determine.
Preferably, the material of mounting groove 1 is plastics, and low cost utilizes the characteristic of its stress deformation simultaneously, and can conveniently be fixed powder stick 2.
