[0002] In the construction of highways and mines, the work of excavating mountains is often involved. The excavated mountains will destroy the original vegetation. If the vegetation is left to recover naturally, it will take a long time. During this period, if there is rainfall, it is very easy to cause natural disasters such as landslides and mudslides. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a mountain topsoil spraying and erosion prevention system, which aims to solve the problem of the long natural recovery time of the original vegetation on the mountain after excavation.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A soil spraying and erosion control system for mountain slopes includes:

[0006] The interception and drainage device includes a top water interception section and a bottom drainage section. The top water interception section is used to intercept water that collects at the top of the mountain slope, and the bottom drainage section is used to discharge water that flows through the mountain slope.

[0007] A sprayed anchor support device includes an anchoring component and a grass-planting stick. The anchoring component is inserted into the slope surface of the hillside and has a first fixing position and a second fixing position distributed sequentially in a vertical direction. The grass-planting stick is located at the second fixing position, and the upper side of the grass-planting stick is used to form a sprayed substrate layer; and...

[0008] A water collection and diversion device is provided at the first fixed position of the anchoring component. The water collection and diversion device has a first port corresponding to the top water interception part and a second port corresponding to the bottom drainage part, which is used to collect water flowing out from the top water interception part and water on the mountain slope and guide the water to the bottom drainage part for discharge.

[0009] Optionally, the top intercepting section includes a slope intercepting channel opened at the top of the mountain slope, and the bottom drainage section includes a slope drainage channel opened at the foot of the mountain slope.

[0010] Optionally, the anchoring assembly includes multiple anchor rods, each anchor rod including a main rod, a first support rod, a second support rod, and a third support rod. The first support rod, the second support rod, and the third support rod are located on the same side of the main rod and are distributed sequentially at intervals along the top of the main rod in the vertical direction. A first fixing position is formed between the first support rod and the second support rod, and a second fixing position is formed between the second support rod and the third support rod.

[0011] Optionally, the shotcrete support device also includes a surface mesh, which is laid on the grass sticks.

[0012] Optionally, the surface mesh is made of galvanized steel wire mesh.

[0018] The advantages of this invention are as follows: This invention provides a mountain topsoil spraying and erosion control system, including a drainage device, a spray anchor support device, and a water collection and diversion device. The spray anchor support device includes an anchoring component and a grass planting stick. The anchoring component is used to anchor the newly excavated mountain. The upper side of the grass planting stick forms a spraying substrate layer, providing adhesion space for the spraying substrate, thereby forming a porous and stable soil structure on the mountain surface that is similar to or better than the natural topsoil, stabilizing the mountain slope soil. By setting up the drainage device and the water collection and diversion device, the runoff from the top of the slope and the slope surface is orderly collected and guided to the bottom drainage section, which greatly reduces the erosion of the sprayed substrate on the mountain where the vegetation has not formed a protective effect during rainfall. It can effectively reduce the impact of rainfall on the sprayed mountain and improve the efficiency and effect of mountain vegetation restoration. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] In the construction of highways and mines, the work of excavating mountains is often involved. The excavated mountains will destroy the original vegetation. If the vegetation is left to recover naturally, it will take a long time. During this period, if there is rainfall, it is very easy to cause natural disasters such as landslides and mudslides.

[0030] In view of this, the present invention provides a hillside topsoil spraying and erosion control system 100, please refer to [link / reference]. Figures 1 to 7 , Figures 1 to 7 A schematic diagram of the structure of the mountain topsoil spraying and erosion prevention system 100.

[0031] Please see Figures 1 to 6The hillside topsoil spraying and erosion control system 100 includes an interception and drainage device 1, a sprayed anchor support device 2, and a water collection and diversion device 3. The interception and drainage device 1 includes a top water interception section 11 and a bottom drainage section 12. The top water interception section 11 is used to intercept water collected at the top of the hillside 200, and the bottom drainage section 12 is used to discharge water flowing across the slope of the hillside 200. The sprayed anchor support device 2 includes an anchoring component 21 and a grass planting stick 22. The anchoring component 21 is used to be inserted into a borehole drilled into the slope of the hillside 200 and has the function of following the slope. The first and second fixed positions are distributed sequentially in the vertical direction. The grass planting stick 22 is set at the second fixed position, and the upper side of the grass planting stick 22 is used to form a sprayed substrate layer. The water collection and diversion device 3 is set at the first fixed position of the anchoring component 21. The water collection and diversion device 3 has a first port corresponding to the top water interception part 11 and a second port corresponding to the bottom drainage part 12, which is used to collect the water flowing out from the top water interception part 11 and the water on the slope of the mountain 200, and guide the water to the bottom drainage part 12 for discharge.

[0032] In the technical solution of this invention, the mountain topsoil spraying and erosion prevention system 100 includes a drainage device 1, a spray anchor support device 2, and a water collection and diversion device 3. The spray anchor support device 2 includes an anchoring component 21 and a grass planting stick 22. The anchoring component 21 is used to anchor the newly excavated mountain 200. The upper side of the grass planting stick 22 forms a spraying matrix layer, providing adhesion space for the spraying matrix, thereby forming a porous and stable soil structure on the surface of the mountain 200 that is similar to or better than the natural topsoil, stabilizing the slope soil of the mountain 200. By setting the drainage device 1 and the water collection and diversion device 3, the runoff from the top of the slope and the slope surface is orderly collected and diverted to the bottom drainage section 12 through the water collection and diversion device 3, which greatly reduces the erosion of the sprayed matrix on the mountain 200 where the vegetation has not formed a protective effect by rainfall. It can effectively reduce the impact of rainfall on the sprayed mountain 200 and improve the efficiency and effect of vegetation restoration on the mountain 200.

[0033] It should be noted that the hydroseeding substrate layer is a liquid layer formed by hydroseeding substrate. The hydroseeding substrate is a uniform mixture formed by dissolving grass seeds, fibers, soil conditioners, compound fertilizers, water, etc. in the hydroseeding machine and mechanically stirring it thoroughly, which has a good spraying effect. At the same time, the addition of wood fiber to the hydroseeding substrate has a quick-setting effect, which can prevent substrate loss and provide a good initial protection effect on the mountain.

[0034] It should also be noted that the hydroseeding substrate layer can not only be formed on the upper side of the grass planting stick 22 as a nutrient layer for grass seed germination, but also on the slope of the hill 200 to fill the pits and depressions of the hill 200 and ensure the quality of appearance.

[0035] Additionally, it should be noted that the planting stick 22 is a rod-shaped grass bag made of high-strength non-woven geotextile material of polypropylene synthetic fibers. The interior is filled with a substrate composed of plant seeds, soil, and fertilizer, exhibiting strong corrosion resistance, good stability, and crack resistance. The planting stick 22 provides an attachment space for the hydroseeding substrate, preventing its loss.

[0036] Further, please refer to Figures 1 to 3 ,as well as Figure 6 The top intercepting section 11 includes a slope intercepting trough opened at the top of the mountain 200, and the bottom drainage section 12 includes a slope drainage trough opened at the foot of the mountain 200.

[0037] For details, please refer to Figure 1 , Figures 4 to 6 The anchoring assembly 21 includes multiple anchor rods 211, each anchor rod 211 including a main rod 2111, a first support rod 2112, a second support rod 2113, and a third support rod 2114. The first support rod 2112, the second support rod 2113, and the third support rod 2114 are located on the same side of the main rod 2111 and are distributed sequentially at intervals along the top of the main rod 2111 in the vertical direction. A first fixing position is formed between the first support rod 2112 and the second support rod 2113, and a second fixing position is formed between the second support rod 2113 and the third support rod 2114. This arrangement enables the anchoring assembly 21 to have both anchoring performance and load-bearing performance.

[0038] For details, please refer to Figure 1 and Figure 5 The sprayed anchor support device 2 also includes a surface mesh 23, which is laid on the grass planting sticks 22; thus, by setting the surface mesh 23, the sprayed substrate is stabilized, providing secondary protection for the slope.

[0039] Furthermore, the surface mesh 23 is a galvanized steel wire mesh. Thus, the surface mesh 23 is a steel wire mesh with a galvanized surface, which effectively prevents rust and extends its service life.

[0040] For details, please refer to Figure 1 and Figure 5 The sprayed anchor support device 2 also includes a bottom layer mesh 24, which is laid on the slope of the mountain 200 and fixed by anchoring components 21. In this way, the bottom layer mesh 24 and the anchor rods 211 can jointly stabilize the slope soil and rock and bear the main slope soil and rock load. In addition, when the bottom layer mesh 24 and the surface layer mesh 23 are installed at the same time, the mountain 200 is doubly fixed, which greatly improves the support effect on the excavated mountain 200 and the sprayed matrix.

[0041] Furthermore, the bottom layer mesh 24 is made of galvanized steel wire mesh, which effectively prevents rust and extends service life.

[0042] For details, please refer to Figure 1 and Figure 6 The water collection and diversion device 3 includes a main drainage pipe 31 and multiple branch drainage pipes 32. The main drainage pipe 31 extends from the top of the hill 200 to the foot of the hill 200, and the first port and the second port are respectively formed at both ends of the main drainage pipe 31. Multiple branch drainage pipes 32 are located on both sides of the main drainage pipe 31, and multiple water inlets are provided on the side wall of each branch drainage pipe 32 facing the slope. In this way, the main drainage pipe 31 is used to collect water from the branch drainage pipes 32 and the hill top intercepting trough, and provides a drainage channel.

[0043] Furthermore, multiple branch drainage pipes 32 on each side of the main drainage pipe 31 are distributed at intervals along the extension direction of the main drainage pipe 31 to achieve multi-stage drainage, which can effectively slow down the water flow velocity, increase the drainage area, and reduce the erosion damage of rainwater to the slope. More specifically, each branch drainage pipe 32 is a PE pipe.

[0044] Furthermore, each water inlet cover is equipped with a filter screen or reverse filter geotextile 33. Both the filter screen and the reverse filter geotextile 33 play a filtering role for rainwater, which can prevent large particles of soil and gravel from entering the branch drainage pipe 32 and clogging the pipe.

[0045] It should be noted that the water inlet is equipped with either a filter screen or a reverse filter geotextile 33 depending on the rainfall in different regions. When the rainfall is high, a filter screen is used; when the rainfall is low, a reverse filter geotextile 33 is used (see [reference]). Figure 7 ).

[0046] For details, please refer to Figures 1 to 3 , Figure 6 and Figure 7 It also includes U-shaped nails 400, and the water collection and diversion device 3 and anchoring assembly 21 are fixedly connected by the U-shaped nails 400. More specifically, each branch drain pipe 32 is fixed by a plurality of spaced U-shaped nails 400.

[0047] The specific construction process for the hillside topsoil spraying and erosion control system 100 is as follows:

[0048] Step S100: Excavate a slope top intercepting channel on the inner side along the slope top line at the top of the mountain, and excavate a slope toe drainage channel at the toe of the slope.

[0049] Step S200: Drill holes on the slope to form multiple holes that are staggered.

[0050] Step S300: Lay the bottom layer mesh 24 on the slope and insert the anchor rod 211 into the borehole and grout into the borehole;

[0051] Step S400: Insert the grass planting stick 22 into the second fixed position of the anchor rod 211, put the surface mesh 23 into the anchor rod 211, and adjust its position to be above the grass planting stick 22.

[0052] Step S500: Form a hydroseeding substrate layer on the slope and on the planting sticks 22;

[0053] Step S600: Install the water collection and diversion device 3 on the slope, and insert the branch drainage pipe 32 into the second fixed position of the anchor rod 211, and fix the branch drainage pipe 32 with U-shaped nails 400.

[0054] It should be noted that the water collection and diversion device 3 is assembled and connected off-site, and then directly assembled on-site, making the overall installation quick and convenient. In addition, the water collection and diversion device 3 will be dismantled and recycled after the vegetation on the 200-meter slope of the mountain has developed and has a certain erosion resistance.
