Problems solved by technology
This conventional dust removal method leads to poor construction conditions in the cave, low dust removal efficiency, and long dust removal time, resulting in high energy consumption for dust removal. At the same time, the formed mud brings a lot of inconvenience to the construction personnel and will affect the construction progress.

Embodiment
[0026] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, the dust removal device for tunnel construction provided in this embodiment includes a support base 1, and several universal wheels 2 are installed on the bottom of the support base 1, and each universal wheel 2 is equipped with a separate locking mechanism. The movement and fixation of the universal wheel 2 can be controlled by a locking mechanism. The bottom of the support seat 1 is also provided with a telescopic heating pipe 3 along its length direction. After the heating pipe 3 is stretched out, it can go deep into the tunnel. The surface of the seat 1 is provided with several fixing holes around its edge. The locking nails 4 are respectively arranged in the fixing holes. The length of the locking nails 4 is greater than the distance between the support seat 1 and the ground. The locking nails 4 pass The connecting rope is fixed near the fixing hole. When in use, the locking nail 4 is ...

The invention discloses a dust removing device for tunnel construction. The dust removing device comprises a support base. Universal wheels and a heating pipe are mounted on the bottom of the supportbase. Locking nails are arranged on the surface of the support base. A support plate is fixedly mounted on the surface of the front section of the support base. A plurality of placement grooves are formed in the surface of the rear section. A plurality of dust absorption holes are formed in the support plate. Rollers are respectively mounted on the two sides and the top of the support plate through connecting members. The rollers are wrapped with dust cloths. The adjacent dust cloths are connected by zippers. A plurality of rows of parallel water ducts are connected in front of the support plate. Water supply pipes communicating with the water ducts are mounted on the back of the support plate. A plurality of atomizing heads are arranged at the bottom of each water duct. An exhaust fan, afan heater, and a purification pool are respectively placed in the placement grooves in the surface of the support base. The dust removing device of the invention can effectively improve the efficiency of dust removal and the effect of dust removal after tunnel blasting, and does not form mud in the ground inside the hole.
Description
technical field [0001] The invention belongs to the technical field of dust removal for tunnel construction, and in particular relates to a dust removal device for tunnel construction. Background technique [0002] The drilling and blasting method is often used for tunnel excavation, and a large amount of dust will be generated during the blasting process, which will seriously affect the health of tunnel construction and management personnel. At present, tunnel blasting and excavation dust is generally diluted by press ventilation, and then the turbid air in the tunnel is discharged to the outside of the tunnel through the principle of flowing air, or the dust is liquefied into mud with water spraying and dust reduction. This conventional dust removal method leads to poor construction conditions in the cave, low dust removal efficiency, and long dust removal time, resulting in high energy consumption for dust removal. At the same time, the formed mud brings a lot of inconven...
