Description

A kind of blasting cartridge

Technical field

The utility model relates to a kind of demolition set more particularly to a kind of directional blasting tubes.

Background technique

Directional blasting utilizes the effect of explosive, the cubic metre of earth and stone throwing in a certain area to the area specified, and substantially accumulates At a kind of blasting technique of required shape, it is mainly used for repairing dam, builds the road, levels land.For labour lack, have inconvenient traffic with And the work point without construction site is especially suitable for.

Before explosion, first it is placed in fried by some key positions of explosion object, after having buried explosive, electronic ignition Conducting wire connects, and thus can almost ignite the explosive at each position simultaneously.When detonation, explosive reaction acutely, is discharged in a flash Huge energy can make local temperature quickly rise to 2000C or more, cause the fusing, rupture rapidly such as masonry.But such explosion Journey will lead to the blasting direction extension of directional blasting, influence the rock for being not required to explosion, cannot play the work of complete directional blasting With.And blasting process can generate a large amount of silt flying dust, noise of blasting is big.

Commonly used in blast hole stemming stemming due under the great force of detonation gas, tamper (stemming) may be because Lose barrier effect for following reasons: (1) intensity is too low, is sheared and is dispelled by detonation pressure；(2) resistance between hole wall is too Small, entire tamper releases blasthole by detonation pressure.For example, general-purpose cement, though it is able to satisfy the general requirement of multiple-row blasting material, It is not able to satisfy the requirement detonated in time, it, can not be small 3~5 even if participating in accelerator and early strength agent because its setting rate is slow When interior reach higher intensity；Waterglass and certain synthesis high molecular materials, though the characteristic with rapid hardening high-strength, using not And higher cost just,.

Therefore, designing a kind of blasting direction can accurately control, and the few directional blasting device of the flying dust silt that explosion generates is Problem in the urgent need to address at present.
