Example 1

[0025] A slope rockfall protection and automatic dust suppression integrated device, such as Figures 1-4 It includes a protective frame 1, a sprinkler assembly 2 and a dam body 3. Both the protective frame 1 and the sprinkler assembly 2 are installed on the top of the dam body 3.

[0026] Dam body 3 is an earth-rock dam, which is formed by mixing and stacking existing soil and stones on site into a trapezoidal dam body.

[0027] The protective frame 1 includes a frame body 10, a rolling stone protection structure 11, and a throwing rod 12.

[0028] The frame 10 is constructed from steel pipe scaffolding and is a single-row frame. The frame 10 is set on the top of the earth-rock dam and is connected and reinforced to the earth-rock dam with anchor steel pipes 107. The anchor steel pipes 107 are driven into the earth-rock dam to a depth of 1m. Several anchor steel pipes are also installed at intervals in the middle of the horizontal bars at the bottom of the frame.

[0029] Specifically, such as Figure 1 , Figure 3 , Figure 4 The frame 10 includes at least two rows of uprights 102, several horizontal and longitudinal bars 103 for connecting the uprights 102, and several sets of scissor braces 104. The materials used are all commonly used on construction sites, with low cost and simple structure.

[0030] The rockfall protection structure 11 and the outrigger rod 12 are respectively installed on both sides of the frame 10, with the rockfall protection structure 11 installed on the side of the frame 10 facing the slope.

[0031] The rockfall protection structure 11 includes an inner wire mesh 111, an outer wire mesh 112, and several airbags 113. The airbags 113 are placed between the inner wire mesh 111 and the outer wire mesh 112. The airbags are continuously arranged along the longitudinal direction of the protection, which can effectively buffer the impact of large rocks generated during slope cutting operations and prevent large rocks from breaking through the protection frame. The inner wire mesh 111 has a higher coverage height than the outer wire mesh 112. The outer wire mesh 112 and airbags 113 are only set in the lower area, which ensures the rockfall protection effect while further reducing costs.

[0032] The mesh size of the wire mesh should not exceed 50mm. The length of the rockfall protection structure 11 should be set according to the site conditions, and it is generally set at the toe of the slope in the area where rocks are falling.

[0033] The airbag 113 is preferably a cylindrical rubber airbag with a diameter of 300mm and a length of 1.2m. The airbags are continuously arranged along the longitudinal direction of the protection, which can effectively buffer the impact of large boulders generated during slope cutting operations and prevent large boulders from breaking through the frame 10.

[0034] One end of the outrigger 12 is connected to the frame 10, and the other end is connected to the dam body 3 through the anchoring steel bar 13. The steel bar is driven into the earth-rock dam 0.5m.

[0035] To ensure the overall stability of the frame, a scissor brace 104 is installed every 2 spans along the longitudinal direction of the frame (between the two rows of longitudinal columns), and a scissor brace is installed every 3 spans along the transverse direction of the frame (between the horizontal columns in the same row). At the same time, care should be taken to avoid the high-pole sprinkler system when installing the scissor braces.

[0036] The steel pipes of the frame 10 are connected by fasteners; each upright of the frame is equipped with a pad 106 at the bottom to prevent the steel pipe from sinking. The pad can be made of wood or channel steel.

[0037] The spray assembly 2 includes an atomizing spray system 22 and a high-pole spray system 21.

[0038] like Figure 1 , Figure 3 The atomizing spray system 22 includes several atomizing nozzles 221, a primary water supply pipe 223 and a secondary water supply pipe 222 arranged along the extension direction of the frame 10. The primary water supply pipe 223 is connected to the steel water pipe 212, the secondary water supply pipe 222 is arranged along the extension direction of the frame 10, and the atomizing nozzles 221 are installed on the secondary water supply pipe 222.

[0039] The high-pole sprinkler system 21 includes a swing sprinkler assembly 211, a steel water pipe 212, and a water pipe support 213 connected to the steel water pipe 212. The swing sprinkler assembly 211 is connected to the steel water pipe 212. The arrangement of the steel water pipe 212 and the water pipe support 213 effectively ensures the stability of the swing sprinkler assembly 211. The steel water pipe 212 and the water pipe support 213 are connected by fasteners such as U-shaped buckles 214. The water pipe support 213 is set between two rows of columns. The water pipe support 213 can be connected to the steel pipe of the frame 10 through U-shaped buckles or anchored to the dam body.

[0040] In this embodiment, the swing spray assembly 211 includes a rocker arm spray gun. After the water pump supplies water, the spray gun will automatically rotate to atomize and spray water to reduce dust, with a spraying distance of 30m-60m.

[0041] The sprinkler assembly 2 also includes a water pump 215 and a water supply pipe 216. The water pump 215 is connected to the steel water pipe 212. The switch box of the water pump is preferably set on the water pipe support 213. The switch box is equipped with a wireless intelligent remote control switch, which can realize remote control to start the water pump. The primary water supply pipe 223 is connected to the steel water pipe 212 through a filter 224 and a check valve 225. After the filter and the check valve are connected, the sediment in the water is filtered. Then the filtered water flows through the primary and secondary water supply pipes to the atomizing nozzles. The atomizing nozzles are set at the top of the protective frame near the slope, with a spacing of 3m and a spraying distance of 2m-10m.

[0042] The atomizing nozzle 221 and the oscillating spray assembly 211 form a near-field and a far-field dust suppression water curtain, which can effectively reduce the dust generated by stones rolling to the foot of the slope during slope cutting construction.

[0043] In actual use, the sprinkler system is remotely activated by management personnel based on the area where dust is generated during slope operations to reduce dust. Once the dust level is reduced, the sprinkler system is remotely deactivated to save water resources.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
