Problems solved by technology
[0004] In the process of drilling in soft rock, most of the holes are dry-drilled, which does not need to inject water, which increases the flying of dust. During the construction process, most workers wear masks, but the masks are replaced It is very frequent, which affects the construction period, and also increases the expenditure and consumption, so we propose a dust removal device to protect the health of the staff

The invention discloses a dust removal method for tunnel construction. The dust removal device includes a base, and the base is a separate structure consisting of a left base plate and a right base plate, the two are fixedly connected by a telescopic column, and the right base The side of the plate facing the left base plate is provided with a storage groove for accommodating telescopic columns; the present invention also proposes a dust removal method for dry drilling of surrounding rock in soft rock tunnels, including the following steps: S1, pushing the dust removal equipment to reach The working place, after arriving at the position, disassembles the bolts and nuts inside the threaded fastening ring 15 . The dust removal equipment used for dry drilling of surrounding rocks in soft rock tunnels uses an air intake fan to transport the air and blows it out from the air outlet at the bottom of the air outlet pipe, continuously blowing the dust generated during work to prevent workers from inhaling The dusty air is equipped with multiple atomizing nozzles at the same time to carry out dust reduction treatment on the air, so that the dust removal equipment has the effect of protecting the health of the staff and removing dust.
Description
technical field [0001] The invention relates to the technical field of tunnel drilling, in particular to a dust removal method for tunnel construction. Background technique [0002] With the development of road construction in our country, the focus of road construction has gradually shifted to the construction of mountain roads, and more and more adverse geological conditions have been encountered in the construction of mountainous areas. The proportion of tunnels with weak and broken surrounding rocks larger. During tunnel construction, drilling is an indispensable task. There are many types and large quantities of drilling holes in the construction, and more dust is generated. Especially when drilling holes on the inner wall of the tunnel, the dust raised will seriously interfere with the sight and health of the construction workers, and affect the construction period and safety. [0003] Moreover, during the construction process, some soft rock geology will appear. Sof...
