Technical field
This disclosure relates to the dedusting noise reduction field that drills, and in particular to a kind of hybrid dedusting denoising device of drilling orifice and brill
Into equipment and working method.
Background technique
With the fast development of Chinese national economy and foundation engineering, mine working engineering, underground tunnel project and outdoor
The engineerings such as exploitation are increasing, and all kinds of drillings of constructing are frequently necessary in engineering construction, as geological prospecting borehole, hydrological observation are bored
Hole, exploitation drilling and blasting boreholes etc., at present mode used by drilling construction be generally divided into rotary, rotary-percussion and
Impact type.
Rotary-percussion and impact type are relatively suitable for that Drilling is harder, complete rock stratum, have the advantages that construction is quick, but
It is that this two kinds of bore modes are easily accompanied by industrial dust during rock drilling, the aerial dispersion degree of dust is higher, outstanding
The floating time is longer, reduces the visibility of Work places, increases the risk of construction operation.Importantly, if constructor
The long-term sucking industrial dust of member may cause pneumoconiosis or other Pulmonary Diseases.In addition, drill bit is in impact solid rock process
In, biggish noise can be generated, construction personnel's neurasthenia can be caused by noise pollution for a long time, or even causes personal pathologic
Variation, and the noise in Work places may also interfere with communication, influence working efficiency, Yi Yinfa contingency.With people
The continuous enhancing of body health and environmental consciousness, existing part research achievement is dedicated to the fugitive dust for solving construction site and noise is asked
Topic.
