Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a supported rock slope greening structure. Background Art

[0002] With the continued development of urban construction and large-scale engineering projects in mountainous areas, slope protection and regreening have become key components of green projects during construction. Compared to soil slopes, rock slopes are often supported quickly after excavation due to their complex geological structure, prone to instability and deformation after unloading, and construction convenience. Shotcrete is often used for protection, but the concrete surface is relatively hard, resulting in poor soil adhesion and soil and water conservation capacity, making regreening of supported rock slopes more difficult.

[0003] Chinese document CN117868175A discloses a rock slope reforestation structure and its construction method. The structure comprises a lattice beam with several compartments, each containing an absorbent plate. The plate is covered with a grille, the outer edges of which are embedded within the lattice beam. The absorbent plate is made of a superabsorbent resin and agricultural rock wool. Agricultural rock wool has good integrity and is resistant to rainwater erosion. It retains a high level of water, can store large amounts of nutrients, and is durable. The superabsorbent resin further enhances water retention and nutrient storage capacity. The basalt grille has excellent mechanical properties and durability, allowing plant roots to intertwine with the grille and agricultural rock wool to form a single structure with strong slope protection.

[0004] The above structure has the following problems: the frame beam structure used is difficult to combine with the existing support measures of the slope, has poor adaptability to the supported slope, and may even increase the external load of the slope. Utility Model Content

[0043] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme of the present application will be further described in combination with specific embodiments.

[0044] Embodiment one:

[0045] In combination with Figures 1 to 10 As shown in the figure, the embodiment is a supported rock slope re-greening structure, which comprises a drip irrigation pipeline 3, a plurality of planting holes 1, a plurality of planting frames 4 and an adjusting assembly 6. The drip irrigation pipeline 3 is installed on the slope bedrock surface through a fixing piece. The drip irrigation pipeline 3 is arranged in a grid shape. The drip irrigation pipeline 3 is used for irrigating the green plants on the slope and providing support for the growth of the green plants. A plurality of planting holes 1 are arranged on the slope bedrock surface. The planting holes 1 correspond to the pipeline nodes of the drip irrigation pipeline 3. Small shrub plants 2 are planted in the planting holes 1. A plurality of planting frames 4 are arranged on the slope surface. The planting frames 4 correspond to the grid of the drip irrigation pipeline 3. Climbing plants are planted in the planting frames 4. The drip irrigation pipeline 3 is internally provided with the adjusting assembly 6. The adjusting assembly 6 can control the irrigation objects of the drip irrigation pipeline 3.

[0046] In some embodiments, as Figure 3 , Figure 4 and Figure 5 As shown in the figure, the drip irrigation pipeline 3 comprises a horizontal connecting pipe 5, a vertical connecting pipe 8 and a node connecting pipe 7. The horizontal connecting pipe 5 and the vertical connecting pipe 8 are both circular pipes. The node connecting pipe 7 comprises elbows, three-way pipes, four-way pipes and the like. The horizontal connecting pipe 5 and the vertical connecting pipe 8 are spliced to form the drip irrigation pipeline 3 through the node connecting pipe 7. Specifically, the drip irrigation pipeline 3 is provided with a water inlet at a position on the top of the slope in the embodiment. The drip irrigation pipeline 3 is connected with an external water supply device through the water inlet. The external water supply device can supply water to the inside of the drip irrigation pipeline 3.

[0047] Further, as Figure 3 shown, two rows of drip irrigation holes 11 are arranged on the horizontal connecting pipe 5 of the drip irrigation pipeline 3 in the axial direction. The two rows of drip irrigation holes 11 are oriented towards the planting holes 1 and the slope, so as to correspond to the planting holes 1 and the planting frames 4 respectively. The adjusting assembly 6 adjusts the irrigation of the drip irrigation pipeline 3 to the small shrub plants 2 or the climbing plants by controlling the opening and closing of the drip irrigation holes 11.

[0048] In some embodiments, as shown in Figures 6 to 9 The adjusting assembly 6 comprises a horizontal rotating shaft 12, rotating rings 14, bevel gears 13, a vertical rotating shaft 9 and a motor. The horizontal rotating shaft 12 is arranged in the horizontal connecting pipe 5 of the drip irrigation pipe 3. A plurality of rotating rings 14 are arranged on the horizontal rotating shaft 12 at intervals. The rotating rings 14 are attached to the inner wall of the horizontal connecting pipe 5. The interval of the rotating rings 14 corresponds to the interval of the drip holes 11. The rotating rings 14 are provided with adjusting holes 15 corresponding to the drip holes 11. The adjusting holes 15 are the same size as the drip holes 11. The end of the horizontal rotating shaft 12 is connected with a bevel gear 13. The vertical rotating shaft 9 is arranged in the vertical connecting pipe of the drip irrigation pipe 3. A plurality of bevel gears 13 are arranged on the vertical rotating shaft 9. The bevel gears 13 of the vertical rotating shaft 9 are meshed with the bevel gears 13 of the horizontal rotating shaft 12. The output end of the motor is drivingly connected with the end of the vertical rotating shaft 9 through a plane gear set.

[0049] Further, in the embodiment, for the clamping cooperation between the horizontal part of the adjusting assembly 6 and the horizontal section of the drip irrigation pipe 3, the first clamping form is that a plurality of sliding grooves are arranged on the inner wall of the horizontal section of the drip irrigation pipe 3 at intervals along the axial direction. The rotating rings 14 are clamped in the sliding grooves. The sliding grooves can horizontally limit the rotating rings 14 to ensure that the adjusting holes 15 on the rotating rings 14 and the drip holes 11 on the drip irrigation pipe 3 are not dislocated. The second clamping form is that limit grooves are arranged on the inner wall of the vertical connecting pipes 8 on both sides of the drip irrigation pipe 3. The outermost end of the horizontal rotating shaft 12 extends and is clamped in the limit grooves. The end of the horizontal rotating shaft 12 is drivingly connected with the limit grooves to horizontally limit the horizontal rotating shaft 12 without affecting the natural rotation of the horizontal rotating shaft 12.

[0050] Further, in the embodiment, since the horizontal rotating shaft 12 and the vertical rotating shaft 9 are drivingly connected through the bevel gears 13, the adjusting assembly 6 can adopt a plurality of arrangement forms in the drip irrigation pipe 3. Specifically, the first arrangement form is shown in Figure 10As shown, a plurality of single-section lateral connecting pipes 5 are connected to form a row of lateral connecting pipes 5, and a set of lateral rotating shafts 12 and corresponding rotating rings 14 are installed in each of the plurality of single-section lateral connecting pipes 5. The two ends of the lateral rotating shaft 12 in the single-section lateral connecting pipe 5 are provided with bevel gears 13, and the lateral rotating shafts 12 in the plurality of rows of lateral connecting pipes 5 are arranged in an array. The connection points of the plurality of single-section lateral connecting pipes 5 are connected with vertical connecting pipes 8, and a vertical rotating shaft 9 and a corresponding bevel gear 13 are installed in each of the vertical connecting pipes 8. The vertical rotating shaft 9 in the vertical connecting pipe 8 on the outermost two sides of the drip irrigation pipe 3 is connected with the bevel gear 13 on the lateral rotating shaft 12 in the lateral connecting pipe 5 through unilateral meshing transmission, and the vertical rotating shaft 9 in the vertical connecting pipe 8 in the middle of the drip irrigation pipe 3 is connected with the bevel gears 13 on the lateral rotating shafts 12 in the lateral connecting pipes 5 on the two adjacent sides through bilateral meshing transmission. The output end of the motor is connected with the end of any vertical rotating shaft 9 through a plane gear set.

[0051] The vertical rotating shaft 9 is driven to rotate by the motor through the plane gear set. Due to the mutual meshing of the bevel gears 13, in this arrangement, the rotating rings 14 in the adjacent lateral connecting pipes 5 in the slice area rotate in opposite directions.

[0052] Specifically, in the second arrangement, a plurality of single-section lateral connecting pipes 5 are connected to form a row of lateral connecting pipes 5. Different from the first arrangement, only one set of lateral rotating shafts 12 is installed inside the single row of lateral connecting pipes 5. The first end of the lateral rotating shaft 12 is connected with a bevel gear 13, and the second end of the lateral rotating shaft 12 is clamped and rotationally connected in a limiting groove. The lateral rotating shafts 12 in the plurality of rows of lateral connecting pipes 5 are arranged in an array. The connection points of the vertical connecting pipes 8 at the middle position are connected with the lateral connecting pipes 5. No vertical rotating shaft 9 and corresponding rotating ring 14 are installed in this part of the vertical connecting pipe 8. Only a vertical rotating shaft 9 is installed in the outermost single-side vertical connecting pipe 8. A plurality of bevel gears 13 are provided on the vertical rotating shaft 9 in the axial direction. The bevel gears 13 on the vertical rotating shaft 9 are correspondingly connected with the bevel gears 13 on the ends of the plurality of lateral rotating shafts 12 through unilateral meshing. The output end of the motor is connected with the end of the vertical rotating shaft 9 through a plane gear set.

[0053] The vertical rotating shaft 9 is driven to rotate by the motor through the plane gear set. Due to the mutual meshing of the bevel gears 13, in this arrangement, the rotating rings 14 in the plurality of rows of lateral connecting pipes 5 all rotate in the same direction. The direction of the rotating ring 14 can be controlled by the motor to control the adjustment hole 15 on the rotating ring 14 to correspond to the drip irrigation hole 11 on the lateral connecting pipe 5.

[0054] Further, the planar gear set comprises a first planar gear and a second planar gear, the output end of the motor is connected with the first planar gear, and the end of the vertical rotating shaft 9 is connected with the second planar gear, the first planar gear and the second planar gear are engaged with each other, so that the vertical rotating shaft 9 can be driven to rotate around its own axis by the motor.

[0055] In some embodiments, the drilling method of the planting hole 1 adopts dry drilling, and when the slope stability is good, water drilling is adopted, and if the planting hole 1 is located at a rock slope crack, the drilling depth only penetrates the shotcrete layer on the slope surface. Specifically, the drilling angle is inclined downward, and the diameter and depth of the drilling are determined according to the root growth diameter and length of the shrub plant 2.

[0056] In some embodiments, the planting soil is uniformly mixed with the climbing plant seeds and then densely filled in the planting hole 1.

[0057] Further, the climbing plant seeds are selected from air root adsorption type climbing plants such as ivy.

[0058] Further, the components of the planting soil in the planting hole 1 and the planting frame 4 need to be newly formulated according to the biological habits of the shrub plant 2 and the climbing plant.

[0059] In some embodiments, the fixing member comprises a steel wire rope and a cement steel nail, the cement steel nail penetrates the shotcrete layer on the slope surface, is anchored into the slope bedrock surface, and cooperates with the steel wire rope to fix the drip irrigation pipe 3 on the slope surface.

[0060] The implementation principle of the supported rock slope greening structure of the embodiment is as follows:

[0061] By covering and laying the drip irrigation pipe 3 on the slope, setting the planting hole 1 at the node of the drip irrigation pipe 3, setting the planting frame 4 in the grid of the drip irrigation pipe 3, planting the shrub plant 2 in the planting hole 1, and planting the climbing plant in the planting frame 4, the "shrub plant 2-drip irrigation pipe 3-climbing plant" greening structure is finally formed, which has good compatibility with the existing rock slope support method of "anchor rod-keel bar-steel mesh-shotcrete layer". By simultaneously designing and constructing, the length of part of the anchor rod can be increased to enhance the integrity of the support structure and the greening structure, and the pre-drilled hole method can be used to avoid repeated construction and reduce the cost.

[0062] Firstly, the drip irrigation pipe 3 is fixed to the slope bedrock surface by the cement steel nails and the steel wire, so that the load of the green structure is transmitted to the bedrock surface, and the effect of the combination of the sprayed concrete layer and the bedrock surface is enhanced. After the small shrub plants 2 grow, the roots of the small shrub plants 2 can provide good support for the drip irrigation pipe 3. The drip irrigation pipe 3 covered on the slope surface is convenient for the tendril growth of the climbing plants. After the climbing plants grow, the climbing plant root system, the drip irrigation pipe 3 and the cement steel nail are in overall stress, which can effectively improve the safety of the overall structure, reduce the damage and wear of the components, and reduce the maintenance and repair costs. If the planting soil and the climbing plant root system are filled in the original slope fissure, the slope stability can be further enhanced.

[0063] Secondly, the drip irrigation pipe 3 can be adjusted to irrigate the small shrub plants 2 or the climbing plants by using the adjusting assembly 6. The vertical shaft 9 is driven to rotate by the motor through the plane gear set. Since the conical gears 13 on the vertical shaft 9 and the conical gears 13 on the horizontal shaft 12 are meshed with each other, the horizontal shaft 12 is driven to rotate around its own axis by the vertical shaft 9, the horizontal shaft 12 drives the rotating ring 14 to rotate in the sliding groove, and the adjusting hole 15 on the rotating ring 14 is switched between the two rows of drip irrigation holes 11 of the horizontal connecting pipe 5 to adjust the irrigation of the small shrub plants 2 in the planting hole 1 or the climbing plants in the planting frame 4. When the adjusting hole 15 on the rotating ring 14 is misaligned with the drip irrigation hole 11 on the horizontal connecting pipe 5, the water in the drip irrigation pipe 3 can flush and clean the inside of the pipe.

[0064] Meanwhile, the grid structure formed by the drip irrigation pipe 3 can be regarded as a multi-stage drop weir, which can slow down the water flow rate, provide sufficient time for the climbing plants to absorb water, and be beneficial to the absorption of the climbing plants. The drip irrigation pipe 3 enhances the durability of the green structure, and the branches and leaves of the climbing plants can cover and hide the drip irrigation pipe 3, ensure the aesthetic effect of the slope greening, and reduce the maintenance cost of the climbing plants.

[0067] The planting hole 1 is arranged on the slope surface by the dry drilling method;

[0069] The drip irrigation pipe 3 is laid and fixed on the slope by the steel wire and the cement steel nails, and the nodes of the drip irrigation pipe 3 correspond to the upper part of the planting hole 1;

[0071] Spraying and sowing the climbing plant planting soil in the planting frame 4.
