Highway tunnel, usually the traffic is large, the tunnel is filled with dust, coupled with the strong adhesion of automobile exhaust oil pollution, cleaning is more difficult, especially the lower part of the wall of the fire board in the tunnel has more dust and mud prints, relying only on daily cleaning It is difficult to completely remove the oil stains on the wall. At present, mechanical cleaning is mainly used.
(1) The inner wall adopts the method of manual operation construction and mechanical operation as supplement. Mainly manual scrubbing is used, and the efficiency is slow.
(2) Tunnel cleaning vehicle, the main principle is to use cleaning agent and rotating brush together, cleaning agent sprayed to the inner wall of the tunnel, with the brush rotation. Mechanical mechanical scrubbing method is adopted. The main feature of tunnel high-pressure water jet cleaning equipment is that high-pressure water converts the kinetic energy of high-pressure water into a blowing force on the wall through the end fan nozzle. The walls are thus cleaned. No other auxiliary measures are used to clean the inner wall of the tunnel to meet the requirements of national standards, so as to meet the cleanliness and beauty of the highway environment and ensure a high-quality traffic environment in the tunnel.
