Method and device for preventing dust pollution during presplitting blasting in slope treatment

Abstract

The invention discloses a method and device for preventing dust pollution during presplitting blasting in slope treatment. For the designed device for preventing dust pollution during presplitting blasting in slope treatment, on one hand, a dust baffle, a connecting cross rod, a suction fan, dust pressing cloth and a dust collecting box are arranged, dust generated in the blasting process can be well and rapidly absorbed and removed, the generated dust can be well collected, especially in the environment with strong wind, the good dust absorption and removal effect can be achieved, and dust pollution is prevented from being expanded; and on the other hand, through the arrangement of a telescopic supporting rod and a stable connecting mechanism and by means of the operation method, corresponding dust treatment can be conducted according to the actual situation of slope treatment, then corresponding dust anti-pollution treatment requirements can be met according to actual blasting, the working efficiency is improved, and the dust anti-pollution treatment working effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of slope treatment, in particular to a method and device for preventing dust pollution by pre-splitting blasting for slope treatment. Background technique [0002] Pre-splitting blasting refers to blasting a penetrating crack with a certain width along the design outline before blasting in the main blasting area when excavating stonework; to buffer and reflect the vibration wave of excavation and blasting, and control its impact on the retained rock. The impact of the destruction of the body, so that it can obtain a relatively smooth excavation contour; pre-splitting blasting is not only widely used on vertical and inclined excavation walls; pre-splitting blasting is also used on regular curved surfaces, twisted surfaces, and horizontal foundation surfaces. ; Pre-splitting blasting is suitable for weak rock formations with poor stability and requiring control of the excavation profile.

Problems solved by technology

[0003] Pre-splitting blasting is widely used in slope treatment engineering, which can improve the work efficiency of slope treatment, but in this process, it will inevitably be accompanied by a large amount of dust, which is very serious to the pollution of the air environment and needs to be treated , the existing dust treatment for pre-splitting blasting is to spray water on the dust area generated to reduce dust, but the actual effect is not ideal. It can only be said that the tip of the iceberg of dust has been treated, and in the windy environment, for The purification treatment of the dust is negligible, which is far from meeting the demand for dust purification control. The method of creating engineering value by polluting the environment is not worth the candle. For this reason, the present invention proposes a slope treatment pre-splitting blasting dust-proof Pollution method and device are used to solve the above problems
