[0002] In China, municipal infrastructure refers to various buildings, structures, equipment, etc. set within the planning and construction scope of urban areas, towns (townships), and provided with paid or unpaid public products and services for residents based on the responsibilities and obligations of the government. The construction of various public infrastructure supporting urban life all belongs to the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, river channels, rail transit, sewage treatment, waste treatment and disposal, etc.

[0003] Chinese Patent Publication No. CN111570125B discloses a dust suppression sprayer, which relates to the technical field of spraying and atomizing equipment. The dust suppression sprayer includes a base, and a telescopic seat and a water tank are fixedly connected to the top of the base in sequence from left to right. A fixed seat is fixedly connected to the top of the telescopic seat, and a water pump is fixedly connected inside the fixed seat. By setting the cooperation of an atomizer, a blowing fan, a conveying channel and a sprayer, the dust suppression effect and working efficiency of the dust suppression sprayer are improved, the environment of the construction site is better purified, the dust content in the air is effectively reduced. By setting a movable seat, the spraying angle of the device can be adjusted, reducing the possibility of working dead angles. By setting the cooperation of a rotating motor, a rotating rod and a dust removal box, the dust suppression box can rotate, thereby expanding the spraying area of the dust suppression sprayer and further improving the dust suppression effect.

[0004] However, most construction sites are muddy ground. Although the above invention can reduce the dust content in the air within a certain range at the construction site, it cannot effectively deal with the dust particles adhering to the ground. The dust on the ground will continuously rise under the influence of environmental wind, affecting normal construction. Summary of the Invention
