The first water supply mechanism includes a water supply pipe connected to the municipal water supply pipe network and a rainwater pool 5 set in the construction site. The rainwater pool 5 is preferably used for water supply. When the rainwater pool 5 is insufficient for water supply, the municipal water supply pipe network is used for water supply. The rainwater first flows into the sedimentation tank 6, passes through the sedimentation tank 6 and is deposited in the inflow rainwater tank 5, and is finally supplied to various places by the rainwater tank pump 7. The rainwater pool also supplies water to the car wash tank 9 set at the entrance and exit of the project.

The tower crane sprinkler assembly is shown in Figure 2. The sprinkler heads 02 of the tower crane sprinkler assembly are arranged on the cantilever 04 of the tower crane, and the sprinkler heads 02 are arranged more densely at the position far from the rotation center 03 of the rotating tower crane than near the rotation center. The water in the rainwater tank is first pressurized by the water pump 01, and then goes along the water pipe vertical rod on the tower body to the horizontal pipe on the tower crane cantilever, and then is transported to the sprinkler for spraying. Adapt to the displacement change between the riser and the horizontal tube when the tower crane cantilever rotates. Taking advantage of the cantilever's wide coverage, free rotation and high spray height, the water mist sprayed by the nozzle on the cantilever can absorb the dust particles in the air, moisten the ground, and prevent the dust from floating into the air again, thereby further reducing dust. Purpose. The material of the water supply pipe of the tower crane sprinkler assembly is PPR, and a 360° rotatable joint is used at the corner position. The model of the sprinkler head 02 is YWYT-BB-1/4-6.5-PP, and the water pump 01 is a vertical pipeline pump ISG65-100.

The purpose of the site fence spray components is to minimize the spread of dust in the construction site to the outside, so as not to pollute the urban environment and affect the lives of residents. The system is erected on a fence at the periphery of the site with a height of 2.5m and a spacing of 3m between sprinklers.

The spray components include PE pipe water supply pipes with a diameter of 9.52mm, high-pressure atomizing nozzles with a spray volume of 49-89cc/min, and vertical pipeline water pumps with a model of ISG65-100. The water supply is supplied by the municipal water supply network or rainwater pool, which is preferred. Rainwater water spray.

In the main stage, the sprinklers of the scaffolding sprinkler components are erected on the scaffolds erected outside the building, and the sprinklers are arranged every 3m. On the one hand, it can be atomized and sprayed to reduce the high-altitude dust caused by the construction of the main stage; on the other hand, it can be used for fire spraying.

The nozzle model of the scaffolding sprinkler assembly is YWYT-BB-1/4-6.5-PP, the water supply pipe is PPR, and the water pump is a vertical pipeline pump of ISG65-100. The sprinkler heads are arranged every four floors, and the sprinkler heads of each lane are arranged at an interval of 3m. In this paper, one sprinkler refers to a water supply pipe located on the upper floor of the building, and this water supply pipe is arranged with several sprinklers.

If the dust concentration is high in a certain place on the construction site, or the spraying of foundation pit spraying components, scaffolding spraying components and tower crane spraying components still cannot achieve the desired effect, a dust collector can be used. The fog cannon can spray atomized droplets, increase the air humidity, combine with the dust and then fall to the ground. It is usually placed at the entrance and exit of the construction site, the mixing area and the material processing area or on both sides of the road. In this embodiment, the dust-removing fog cannons are set at the northwest corner and the southeast corner of the foundation pit, and can be controlled by manual or integrated button remote control. A bucket is placed at the bottom of the dust collector and fog cannon, and its water source can be provided by the municipal pipe network.

In order to make this embodiment run automatically, a corresponding automatic sprinkler system can be installed. The automatic sprinkler system is composed of sensors, GPRS wireless transmission modules, control centers and other parts. The principle is that the sensor monitors the PM2.5 concentration value within its range in real time. , and transmit the value to the control center for real-time recording. When the concentration of PM2.5 is higher than the upper limit, the control center controls the water pump of the corresponding component of the corresponding spray mechanism to start water supply. When the sensor detects that the concentration of PM2.5 has returned to the normal level for 5 consecutive minutes, the control center sends an instruction to the water pump to stop spraying water. The specific process is shown in Figure 6.

Example 2, the dust suppression system is the same as Example 1 except for the tower crane spray assembly. As shown in FIG. 3 , the tower crane spray assembly includes a water pump 11 arranged on the ground, a sprinkler head 14 arranged on the cantilever of the tower crane, a water supply pipe 13 connecting the water pump and the sprinkler head, a water storage tank and a secondary water pump, and the water storage tank is arranged in the On the tower body of the tower crane, the water outlet pipe of the water pump is connected to the water storage tank, the water inlet pipe of the secondary water pump is arranged in the water storage tank, and the water outlet pipe of the secondary water pump is connected to the nozzle of the tower crane spray assembly.

This embodiment mainly adds a water storage tank and a secondary water pump, mainly to reduce the investment of equipment. Therefore, when the tower crane is not high, the ground tower crane can fully supply water, but after a certain height, if the secondary water storage in the air is not used In this way, a high-cost high-pressure water pump and a high-pressure water pipe are required. Therefore, in this embodiment, a water storage tank and a secondary water pump are used to relay water storage.

Example 3, the dust suppression system is the same as Example 1 except for the tower crane spray assembly. As shown in Figures 4 and 5, the tower crane spray assembly includes a water pump 31 arranged on the ground, a cantilevered sprinkler head (not shown in the figure) and a water supply pipe 32 connecting the water pump and the sprinkler head. This set of components has a lower height of the tower crane. However, when the construction building gradually rises and the tower crane rises, the water pressure of the water supply will also increase. As the water pressure increases, the price of the required water pump 31 and water supply pipe 32 will increase Rapid ascent.

In order to save costs and utilize resources reasonably, the tower crane spray assembly in this embodiment also includes a water storage mechanism and a second water supply mechanism. The water storage mechanism includes a guide rail fixed under the tower crane cantilever, and several folding brackets 37 installed on the guide rail. The folding bracket is preferably made of aluminum alloy, and is fixed on the water storage tank 35 on the lower end face of the folding bracket 37 by glue and rope. Plate 3101, the folding push plate 3101 is preferably fixed on the outermost folding bracket, when the transport mechanism drives the hook to slide, the transport mechanism 310 will push the folding bracket 37 through the folding push plate 3101, and finally the water storage soft tank is closed. Fold it up to prevent the water storage mechanism from affecting the normal operation of the tower crane; the second water supply mechanism includes a sling 39 for locking the hook, a tank 38 for accommodating liquid, and a water absorption component fixed on the transport mechanism of the hook, and the tank 38 is preferably Made of stainless steel, the water absorption assembly includes a water suction pipe 381 that can extend into the tank body when the tank body rises to the highest point, a water outlet pipe connecting the water storage soft tank, and a water pump connecting the water suction pipe 381 and the water outlet pipe, because the transport mechanism is always on the hook. When the hook lifts the tank body through the sling, the suction pipe 381 will naturally fall into the tank body 38, and the water pump here can directly choose a light and small water pump due to the low height of the pump to reduce the cost. .

When in use, the worker injects water into the tank body 38 on the ground, and then instructs the tower crane to lower the hook, connect the sling 39 to the hook, the tower crane lifts the tank body 38, and uses the power of the tower crane to raise the water for spraying. , after rising to a certain position, the water suction pipe 381 of the water absorption assembly extends into the tank body, at this time, the water pump of the water absorption assembly is started, and the water in the tank body is injected into the water storage soft tank, and the water outlet in the water storage soft tank is from the water head 36 flows out. Since the height of the tower crane is high at this time, the water flowing out from the water outlet 36 will decompose into fine water droplets by itself before falling to the ground, so as to achieve the purpose of dust reduction. Remove the sling and trough when no dust suppression is required. When the hook of the tower crane slides horizontally, it can push the folding bracket through the transport mechanism, so that the water storage mechanism can be folded by itself, so as to avoid affecting the normal operation of the tower crane.
