First water supply mechanism includes the delivery pipe with municipal water supply pipe network intercommunication and sets up the rainwater pond 5 in the building site, preferentially chooses 5 water supplies in the rainwater pond, when 5 retaining of rainwater pond are not enough to supply with, adopts municipal water supply pipe network to supply water. Rainwater flows into the sedimentation tank 6 first, is precipitated in the sedimentation tank 6 and flows into the rainwater pool 5, and finally is supplied to all places by the rainwater pool pump 7. The rain pool also supplies water for the car washing groove 9 arranged at the inlet and the outlet of the project.
As shown in figure 2, spray heads 02 of the tower crane spray assembly are arranged on a cantilever 04 of the tower crane, and the spray heads 02 at the position far away from a rotation center 03 of the rotating tower crane are arranged more densely than those close to the rotation center. The water in the rainwater pond is pressurized by the water pump 01 and then is conveyed to the horizontal pipe on the tower crane cantilever along the water pipe vertical rod on the tower body, and the water is sprayed by the spray head, and the water pipe vertical pipe and the horizontal pipe are connected through a 360-degree rotary joint so as to adapt to the displacement change between the vertical pipe and the horizontal pipe when the tower crane cantilever rotates. By utilizing the characteristics of wide coverage range, free rotation and high spraying height of the cantilever, the water mist sprayed by the spray head on the cantilever can adsorb the dust raising particles diffused in the air to wet the ground and prevent the dust from floating in the air again, thereby further achieving the dust settling purpose. The water supply pipe of the tower crane spray assembly is made of PPR, a connector capable of rotating 360 degrees is adopted at a corner position, the type of the spray head 02 is YWYT-BB-1/4-6.5-PP, and the water pump 01 is a vertical pipeline pump ISG 65-100.
The site enclosure spraying component is used for reducing the dust in the construction site as much as possible to be diffused to the outside so as to avoid polluting the urban environment and influencing the life of residents.
