Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment for building construction, in particular to an environmental protection device for road, bridge and tunnel building construction. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. In the process of road, bridge and tunnel construction, a large amount of dust will be generated, and dust reduction is required to improve the environmental protection effect of the site and avoid human inhalation of excessive dust that affects health.

[0003] In the existing road, bridge and tunnel construction, dust reduction is usually carried out by spraying dust reduction on site with a fog cannon barrel. In this regard, publication No. CN218687682U discloses a road dust reduction device for construction, including a dust reduction equipment body and a fog cannon barrel. The lower surface of the dust reduction equipment body is provided with four bases. The outer surface of the fog cannon barrel is rotatably connected to a support frame, and the support frame is rotatably connected to the upper surface of the dust reduction equipment body. Under the action of the rotating component, the fog cannon barrel rotates, and the dust reduction equipment body is started at this time. Water is sprayed through the fog cannon barrel to reduce dust. Since the rotating seat rotates at a fan-shaped angle, the fog cannon barrel rotates in a fan-shaped manner to carry out dust reduction in a range. By adjusting the component, the position of the sliding seat on the inner wall of the rotating seat is changed, so that the rotation range of the connecting seat, the support frame and the fog cannon barrel is changed, thereby achieving the effect of changing the dust reduction range.

[0004] The above-mentioned technology uses a fog cannon to spray dust on the construction road, which can improve the environmental protection effect on site. However, due to the large spray distance and width range of the fog cannon, it can only be used in open areas with few residents on the side or far away from concentrated people. There are the following shortcomings when using it:

[0005] 1. It is not possible to accurately and flexibly adjust the dust reduction and suppression width according to the width of the construction road surface. When there are streets with concentrated residents and people on both sides of the road, (directly using fog cannons to spray dust over a large width over a long distance may easily result in a large amount of water being sprayed on people or causing moisture in the residents' homes. When used in such areas, it is easy to affect the normal lives of people and residents, especially when the weather is cooler, which will cause greater confusion to roadside personnel), it is difficult to apply it in such an environment.
