[0040] S2: A plurality of spraying devices 3 are installed on the top of the inner shielding wall 2, and the length of the spraying devices 3 is consistent with the length of the adjacent side of the edge working area 13 and the inner shielding wall 2; the spraying devices 3 are rotatably connected to the inner shielding wall 2; and a control unit for controlling the spraying devices 3 is provided in each edge working area 13;

[0041] S3: an outer adsorption wall 4 is arranged around the inner shielding wall 2, a corridor 41 is provided between the outer adsorption wall 4 and the inner shielding wall 2, a dust suppression net 42 structure is provided on the outer adsorption wall 4, and the dust suppression net 42 structure corresponds to the spraying equipment 3; the dust suppression net 42 structure has multiple layers of dust suppression nets 42, and the dust suppression net 42 is higher than the inner shielding wall 2;

[0042] S4: When the edge work area 13 is under construction, the control unit in the corresponding edge work area 13 is activated to allow water to flow into the spraying device 3, and the spraying device 3 is controlled to rotate toward the outer adsorption wall 4 so that the water is sprayed on the outer dust suppression net 42, and then the control unit is activated to control the spraying device 3 to tilt toward the edge work area 13 and spray water above the edge work area 13;

[0043] S5: Observe the amount of dust on the dust suppression net 42. When the dust covers the dust suppression net 42, start the control unit to control the spraying device 3 to rotate toward the dust suppression net 42 and clean the dust suppression net 42. After cleaning, start the control unit again to control the spraying device 3 to spray water above the edge working area 13.

[0044] Compared with the prior art, the dust suppression system for road construction provided by the present invention is as follows: before construction, the annular area near the side of the construction area 1 is divided into multiple edge work areas 13, and the inner shielding wall 2 and the outer adsorption wall 4 are arranged in sequence on the outer side around the construction area 1, and a walking corridor 41 is set between the outer adsorption wall 4 and the inner shielding wall 2, and the inner shielding wall 2 is arranged adjacent to the multiple edge work areas 13; at the same time, a spraying device 3 is installed on the inner shielding wall 2, and a dust suppression net 42 structure composed of multiple dust suppression nets 42 is installed on the outer adsorption wall 4; because the construction in the multiple edge work areas 13 has a greater impact on the external environment, the control unit is started to first control the spraying device 3 to spray the dust. The device 3 rotates toward the outer adsorption wall 4, and the spraying device 3 sprays water to wet the dust suppression net 42, and then the spraying device 3 is controlled to rotate toward the edge working area 13 and spray water toward the edge working area 13; the dust generated during the construction process is wetted by the water sprayed toward the edge working area 13 by the spraying device 3, and the dust passing through the spraying device 3 is restricted by the wet dust suppression net 42, so that the dust falls on the dust suppression net 42 and no longer spreads outward; when the dust suppression net 42 is covered with a lot of dust and cannot be used anymore; the control unit is started again to clean the corresponding dust suppression net 42, and the dust on the dust suppression net 42 is washed off and continued to be used. In this way, the dust suppression effect is improved, and the harm caused by a large amount of dust being scattered outward is reduced.

[0045] The control unit includes a first control module for controlling the rotation of the spraying device 3 and a second control module for turning on or off the spraying device 3. The spraying device 3 is connected to a water source through a water pipe, a valve is provided on the water pipe, and the second control module is electrically connected to the valve. The water pipe adopts a hose to adapt to the rotation of the spraying device 3 and other operations.

[0046] See also Figures 1 to 5 As a specific embodiment of the dust reduction system for road construction provided by the present invention, the spraying device 3 has multiple universal nozzles. In step S4, when one edge work area 13 is under construction, the control units in the two adjacent edge work areas 13 are started to make the corresponding two spraying devices 3 work; at the same time, the multiple universal nozzles are driven to rotate toward the edge work area 13 under construction, and water is sprayed toward the edge work area 13 under construction; that is, the universal nozzle has a ball hinge, and the spraying device 3 is provided with an electric push rod for driving the universal nozzle to rotate, and the electric push rod is electrically connected to the control unit. When a certain edge work area 13 is under construction, not only the spraying device 3 corresponding to the edge work area 13 is started, but also the two spraying devices 3 in the two edge work areas 13 adjacent to the edge work area 13 are turned on. At the same time, with the help of the electric push rod, the universal nozzles are all sprayed toward the edge work area 13 under construction, thereby improving the dust reduction effect of the edge work area 13 under construction. At the same time, the dust suppression nets 42 corresponding to the two adjacent edge working areas 13 are also wetted, which can effectively increase the dust suppression range.

[0047] As a specific embodiment of the dust reduction system for road construction provided by the present invention, a plurality of cameras are provided on the inner shielding wall 2, and the plurality of cameras correspond one to one with the plurality of spraying devices 3; in step S4, when the spraying device 3 is controlled to spray on the outer dust suppression net 42, the camera photographs the dust coverage on the dust suppression net 42, and the camera transmits a signal to the control unit; the control unit controls the plurality of universal nozzles to rotate to wash away the dust on the dust suppression net 42; the camera is arranged to observe the dust adhesion on the dust suppression net 42 in real time, and when there is a lot of dust on the dust suppression net 42, the camera transmits a signal to the control unit, and after the control unit analyzes and processes the signal, the spraying device 3 is controlled to rotate toward the dust suppression net 42, thereby washing away the dust on the dust suppression net 42; at the same time, the universal nozzle can be started to rotate to clean the dust suppression net 42 more completely and thoroughly.

Since the inner working area 14 is far away from the spraying devices 3 on the side, the direction of dust diffusion is difficult to determine, so multiple spraying devices 3 close to the inner working area 14 can be started to limit the spread of dust outward in a larger range.

[0049] See also Figures 2 to 5 As a specific embodiment of the dust suppression system for road construction provided by the present invention, in step S2, the spraying surface of the spraying device 3 is a convex surface 31 protruding upward, and a plurality of uniformly arranged nozzles are arranged on the convex surface 31, and the axis of the spray hole of each nozzle is perpendicular to the convex surface 31; the upper end of the inner shielding wall 2 is provided with a convex surface 31 for accommodating the spraying device 3 and a plurality of nozzles.
