Description

Technical Field

[0001] This utility model relates to the field of slope treatment technology, specifically a comprehensive treatment system for rock slopes in water-scarce areas. Background Technology

[0002] In mountainous urban construction, road administration, mining, and other engineering activities, rock slopes are inevitably generated. Managing rock slopes in water-scarce areas presents numerous challenges. On the one hand, rock slopes themselves have poor stability and are prone to landslides and collapses under the influence of natural factors such as weathering, rainfall, and earthquakes, threatening the safety of surrounding buildings, roads, and people. On the other hand, water-scarce areas lack water resources, making plant growth difficult, and traditional slope greening methods are ineffective, resulting in a deteriorated slope ecological environment and severe soil erosion.

[0003] Currently, common methods for supporting rock slopes mainly include retaining walls and anti-slide piles. While these methods can improve slope stability to some extent, they suffer from high costs, complex construction, and do not consider slope greening and ecological restoration. Traditional slope greening methods, such as hydroseeding, struggle to achieve the desired greening and ecological restoration effects in water-scarce areas due to insufficient water. Therefore, developing a comprehensive management method that can effectively improve the stability of rock slopes in water-scarce areas while also achieving slope greening and ecological restoration is of significant practical importance. Utility Model Content

[0004] This invention overcomes the shortcomings of existing technologies and proposes a comprehensive management system for rock slopes in water-scarce areas, so as to achieve effective support and greening of rock slopes in water-scarce areas.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A comprehensive treatment system for rock slopes in water-scarce areas includes an active net protection system consisting of short anchor bolts, a grid mesh, and an inner layer of cable net, and a vegetation system consisting of long anchor bolts, superabsorbent polymer sheets, vegetation bags, and an outer layer of cable net.

[0007] A grid mesh is laid on the slope surface, and several inner layers of cable netting are laid on the upper surface of the grid mesh. Several short anchors arranged in an array extend through the inner layers of cable netting and the grid mesh and are fixed inside the slope to form an active net protection system. The number of inner layers of cable netting is equal to the number of short anchors. A super absorbent polymer sheet is laid on the upper surface of the active net protection system, and a vegetation bag is laid on the upper surface of the super absorbent polymer sheet. An outer layer of cable netting is laid on the upper surface of the vegetation bag. The super absorbent polymer sheet, vegetation bag and outer layer of cable netting are fixed on the slope by several long anchors arranged in an array to form a vegetation system.

[0008] Furthermore, short and long anchor bolts are spaced apart and arranged in a quincunx pattern.

[0009] Furthermore, the rock penetration length of the long anchor bolt is consistent with the rock penetration length of the short anchor bolt.

[0010] Furthermore, the superabsorbent polymer sheet is a superabsorbent polymer sheet with a thickness of 5mm to 10mm.

[0011] Furthermore, the outer layer of the cable net is fixed by connecting and securing longitudinal and transverse support ropes with long anchor rods.

[0012] Furthermore, the planting bags are made into long strips, 20-30cm wide, according to the slope height.

[0013] Furthermore, the outermost and innermost layers of the planting bag are made of nylon fiber mesh, the next outermost layer is non-woven fabric, the middle layer is a mixture of plant seeds and fertilizer, and the next innermost layer is non-woven cotton fiber cloth.

[0014] The beneficial effects of this utility model compared to the prior art are as follows:

[0015] 1. Improve slope stability: This utility model forms a stable active protection system by combining two batches of anchor bolts with grid mesh and cable net, which effectively enhances the stability of rock slopes and reduces the risk of geological disasters such as landslides and collapses.

[0016] 2. Solving the problem of ecological restoration of rocky slopes in water-scarce areas: Vegetation bags can absorb and store large amounts of water, providing a continuous water supply for plant growth in water-scarce areas, greatly improving the survival rate of plants in arid environments, and solving the problem that traditional greening methods are difficult to implement in water-scarce areas. Plant seeds inside the vegetation bags grow under suitable conditions, achieving slope greening and ecological restoration, improving the ecological environment of rocky slopes in water-scarce areas, and reducing soil erosion.

[0017] 3. Simple construction and low cost: This utility model requires no complex technology or process during implementation, and the construction difficulty is low. The materials involved in the construction process are all common and readily available materials on the market, which are easy to obtain and have controllable costs; it has high versatility and is suitable for various similar construction scenarios, which can effectively improve construction efficiency.

[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0023] See Figure 1 and Figure 2 This embodiment proposes a comprehensive treatment system for rock slopes in water-scarce areas, including an active net protection system consisting of short anchor bolts 1, a grid mesh 3 and an inner stranded net 4, and a vegetation system consisting of long anchor bolts 2, a superabsorbent polymer sheet 5, a vegetation bag 6 and an outer stranded net 7.

[0024] A grid mesh 3 is laid on the slope surface. Several inner-layer cable nets 4 are laid on the upper surface of the grid mesh 3. Several short anchor bolts 1 extend through the inner-layer cable nets 4 and the grid mesh 3 and are fixed inside the slope. The number of inner-layer cable nets 4 and short anchor bolts 1 are equal. Several short anchor bolts 1 are evenly distributed in an array on the slope, fixing several inner-layer cable nets 4 and grid mesh 3 to the slope surface to form an active net protection system.

[0025] A layer of superabsorbent polymer sheet 5 is laid on the upper surface of the active net protection system. A layer of vegetation bag 6 is laid on the upper surface of the superabsorbent polymer sheet 5. An outer layer of cable net 7 is laid on the upper surface of the vegetation bag 6. The superabsorbent polymer sheet 5, vegetation bag 6 and outer layer of cable net 7 are fixed to the slope by a number of long anchor rods 2 distributed in an array. The long anchor rods 2 extend all the way into the interior of the slope. Short anchor rods 1 and long anchor rods 2 are arranged at intervals of 1.5m in a quincunx pattern.

[0026] The long anchor 2 has the same rock-penetrating section as the short anchor 1. The long anchor 2 protrudes 30cm above the ground, and the other end penetrates into the rock layer to connect and fix the superabsorbent polymer sheet 5, the planting bag 6, and the outer strand net 7.

[0027] For the superabsorbent polymer (SAP) sheet 5, select a 10mm thick SAP sheet and cut and splice it according to the slope shape. During installation, overlap the SAP sheets by 5cm and secure them with special adhesive or fixing nails to prevent movement. The SAP sheet material is an existing technology, such as materials composed of SAP.

[0028] The planting bags 6 are made into long strips, 20-30cm wide, according to the slope height. The outermost and innermost layers are nylon fiber mesh, the next outermost layer is thickened non-woven fabric, the middle layer is a mixture of plant seeds, long-acting compound fertilizer, and bio-fertilizer, and the next innermost layer is non-woven cotton fiber cloth that can decompose automatically in a short period of time. They are laid down from top to bottom along the slope, with the planting bags containing plant seeds, nutrient soil, and water-retaining agent tightly arranged on the super absorbent polymer sheet 5.

[0029] The outer layer of cable net 7 is laid from top to bottom and is fixed by longitudinal and transverse support ropes and long anchor rods 2.

[0030] The construction method of the comprehensive treatment system for rock slopes in water-scarce areas described in this embodiment is as follows:

[0031] 1. Slope Shaping: The rock slope is shaped by removing loose rocks and boulders to achieve a roughly flat surface with a gradient meeting design requirements. This step is fundamental for subsequent construction, ensuring slope stability and the safety of the work. Specifically, specialized slope clearing equipment, such as hydraulic breakers and pneumatic drills, can be used to clear the rock slope. Larger loose rocks are removed by blasting or hoisting; smaller boulders and gravel are cleared using a combination of manual labor and machinery. During the clearing process, the slope must be strictly adjusted according to the design gradient to ensure that the flatness error is within acceptable limits.

[0032] 2. Installation of the active net protection system: Short anchor bolts 1 are installed at certain intervals on the slope; holes are drilled inside the rock and short anchor bolts 1 are installed. The holes are drilled and cleaned to the planned depth, and the hole depth should be at least 5cm longer than the designed anchoring length. Cement mortar is used for grouting. One side of the short anchor bolt 1 is fixed inside the rock to form a stable support structure.

[0033] One end of the short anchor bolt 1 is inserted into the rock strata, and the other end is connected to the grid mesh 3 and the inner layer of cable net 4. The grid mesh 3 and the inner layer of cable net 4 are laid sequentially from top to bottom and fixed to the slope surface. They are then firmly secured with the short anchor bolt 1, forming an active slope protection system. The grid mesh 3 and the inner layer of cable net 4 can provide initial protection to the slope surface, prevent rockfalls, and enhance the overall stability of the slope.

[0034] Specifically, the grid mesh 3 is laid on the slope, ensuring it adheres tightly to the surface. Then, the inner layer of cable mesh 4 is placed over the grid mesh 3, and the grid mesh 3 and the inner layer of cable mesh 4 are fixed to the slope using the nuts and washers provided with the short anchor bolts 1. During the fixing process, it is ensured that the grid mesh 3 and the inner layer of cable mesh 4 are taut and without any loosening. The short anchor bolts 1 are made of high-strength threaded steel, with a diameter determined according to the slope rock conditions and design requirements, generally 16-30mm. Holes are drilled on the slope at a spacing of 1.2-1.5m, ensuring the anchor bolt anchorage length is not less than 1.0m. Grouting is used to anchor the short anchor bolts 1.

[0035] 3. Installation of the water-retaining vegetation system: Construct a vegetation system on the slope and install long anchor bolts 2 at certain intervals. Use the outer layer of cable net 7 and long anchor bolts 2 to further fix the superabsorbent polymer sheet 5 and vegetation bag 6 to the slope.

[0036] Specifically, the long anchor bolt 2 is made of steel bars with a diameter of 16-20mm. The length of the section exposed on the slope is determined according to the slope conditions and anchoring requirements, generally 30cm~40cm. Holes matching the vertical section of the long anchor bolt 2 are drilled at certain intervals on the slope, with the hole depth ensuring that the anchoring length of the vertical section of the long anchor bolt 2 is not less than 1.0m. The vertical section of the long anchor bolt 2 is inserted into the holes, and grouting is used to anchor the long anchor bolt 2.

[0037] The elongated anchor bolt 2 structure effectively anchors the superabsorbent polymer sheet 5 and the planting bag 6 to the slope, preventing displacement or detachment under gravity, rain erosion, and other forces, thus ensuring the stability of the entire protection and greening system. The superabsorbent polymer sheet 5 possesses superior water absorption and retention capabilities, absorbing and storing moisture to ensure a reliable water source for subsequent plant growth. The planting bag 6 contains plant seeds and nutrient soil suitable for water-scarce areas, creating favorable conditions for plant growth.

[0038] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
