Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, in particular to a supported rock slope regreening structure and a construction method thereof. Background Art

[0002] With the continuous development of urban construction and large-scale engineering projects in mountainous areas, slope protection and greening have become key links in green engineering during the construction process. Compared with soil slopes, rock slopes are often supported in a short time after excavation due to their complex geological structure, easy instability and deformation after unloading, and the convenience of construction. Shotcrete is usually used for protection. The surface hardness of concrete is high, and the soil adhesion effect and soil and water conservation capacity are poor, making it more difficult to green the supported rock slopes.

[0003] The Chinese document with publication number CN117868175A discloses a rock slope regreening structure and a construction method thereof, comprising: a frame beam, a plurality of compartments are provided on the frame beam, an absorption plate is provided in the compartment, the surface of the absorption plate is covered with a grille, and the outer edge of the grille is embedded in the frame beam. The absorption plate is made of highly absorbent resin and agricultural rock wool. Agricultural rock wool has good integrity, will not be damaged by rainwater erosion, has strong water retention capacity, can store a large amount of nutrients, and has good durability. Highly absorbent resin can further improve water retention capacity and nutrient storage capacity. The grille made of basalt has excellent mechanical properties and good durability. The plant root system can be interwoven with the grille and agricultural rock wool to form a whole with strong slope protection ability.

[0004] The above structure has the following problems: the adopted frame beam structure is difficult to be combined 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. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the above-mentioned problems, a supported rock slope greening structure and a construction method thereof are provided.

[0006] The technical solution adopted by the present invention is: a supported rock slope regreening structure, comprising:

[0007] Drip irrigation pipes are installed on the bedrock surface of the slope through fixings. The drip irrigation pipes are arranged in a grid shape. The drip irrigation pipes are used to irrigate the green plants on the slope and provide support for the green plants to grow.

[0008] A plurality of planting holes are arranged on the bedrock surface of the slope, the planting holes correspond to the pipeline nodes of the drip irrigation pipeline, and small shrubs are planted inside the planting holes;

[0009] A plurality of planting frames are arranged on the surface of the slope, the planting frames correspond to the grids of the drip irrigation pipes, and climbing plants are planted inside the planting frames;

[0010] The regulating component is arranged inside the drip irrigation pipe, and the regulating component is used to control the irrigation object of the drip irrigation pipe.

[0011] Through the above technical means, drip irrigation pipes are set on the slope, planting holes and planting frames are set on the slope, small shrubs are planted in the planting holes, and climbing plants are planted in the planting frames. The drip irrigation pipes are used to irrigate the small shrubs and climbing plants, and simultaneously provide support for the plants to grow on the slope. When the small shrubs and climbing plants grow up, their plant roots penetrate deep into the slope, and can be combined with the supporting structure on the slope with the help of drip irrigation pipes.

[0012] In some embodiments, two rows of drip irrigation holes are axially arranged on the horizontal section of the drip irrigation pipe, and the directions of the two rows of drip irrigation holes correspond to the planting holes and the planting frames respectively. The regulating component adjusts the drip irrigation pipe to irrigate the small shrubs or the climbing plants by controlling the opening and closing of the drip irrigation holes.

[0013] In some embodiments, the adjustment component includes a transverse rotating shaft, a swivel, a bevel gear, a vertical rotating shaft and a motor. The transverse rotating shaft is rotatably arranged in the horizontal section of the drip irrigation pipe. A plurality of the swivels are arranged at intervals on the transverse rotating shaft. The spacing of the swivels corresponds to the spacing of the drip irrigation holes. The swivel is provided with adjustment holes corresponding to the drip irrigation holes. The end of the transverse rotating shaft is connected to the bevel gear. The vertical rotating shaft is rotatably arranged in the vertical section of the drip irrigation pipe. A plurality of the bevel gears are provided on the vertical rotating shaft. The bevel gears of the vertical rotating shaft are meshed with the bevel gears of the transverse rotating shaft. The output end of the motor is transmission-connected to the end of the vertical rotating shaft via a planar gear set.

[0014] In some embodiments, a plurality of sliding grooves are provided on the inner wall of the horizontal section of the drip irrigation pipe at intervals along the axial direction, and the swivel is rotatably engaged in the sliding grooves, and the sliding grooves can limit the swivel in the horizontal direction.

[0015] In some embodiments, the planting holes are dry drilled. When the slope stability is good, water drilling is used. If the planting holes are located in the cracks of the rock slope, the drilling depth only penetrates the sprayed concrete layer on the slope surface.

[0016] In some embodiments, the planting soil and the climbing plant seeds are uniformly mixed and then densely filled into the planting hole.

[0017] In some embodiments, the climbing plant seeds are selected from climbing plants with aerial roots, including Parthenocissus tricuspidata.

[0018] In some embodiments, the fixing member includes a steel wire rope and a cement steel nail. The cement steel nail penetrates the sprayed concrete layer on the slope surface and cooperates with the steel wire rope to fix the drip irrigation pipe to the slope surface.

[0019] In some embodiments, the drip irrigation pipeline includes a transverse connecting pipe, a vertical connecting pipe and a node connecting pipe, and the transverse connecting pipe and the vertical connecting pipe are spliced ​​via the node connecting pipe to form the drip irrigation pipeline.

[0020] Another technical solution adopted by the present invention is: a construction method of a supported rock slope greening structure, comprising the following steps:

[0021] On the slope surface, planting holes are arranged by dry drilling;

[0022] Mix the small shrub plant seeds, nutrient solution and planting soil to obtain small shrub planting soil, and fill the soil into the planting hole densely;

[0023] The drip irrigation pipe is laid and fixed on the slope by steel wire rope and cement nails, and the nodes of the drip irrigation pipe are located above the planting holes;

[0024] Planting frames are arranged within the grid formed by the drip irrigation pipes;

[0025] Spray climbing plant planting soil in the planting frame.

[0026] The beneficial effects of the present invention are:

[0027] 1. By setting a drip irrigation pipe on the slope, setting planting holes for planting small shrubs at the nodes of the drip irrigation pipe, and setting a planting frame for planting climbing plants in the grid of the irrigation pipe, on the one hand, the drip irrigation pipe can irrigate the green plants in the planting holes and the planting frame, and on the other hand, the small shrubs can provide support for the irrigation pipe after they grow up, and the small shrubs and irrigation pipes can also provide attachment support for the growth of climbing plants on the slope. Through the combined structure of "small shrubs-climbing plants-drip irrigation pipes", a support effect similar to that of "anchor rods-keel bars-wire mesh" is achieved. The combined structure can form an effective combination with the existing slope support structure (such as a shotcrete layer), achieving good compatibility with the existing support structure, and can support the slope while playing a role in consolidating the soil, thereby ensuring the overall stability of the slope.

[0028] 2. The grid structure formed by the drip irrigation pipe can also slow down the water flow speed on the slope, providing sufficient time for climbing plants to absorb water. In addition, the drip irrigation pipe is equipped with an adjustment component, which can control the drip irrigation of small shrubs and climbing plants, so that plant seeds can take root and grow quickly, speeding up the process of slope regreening, thereby improving the durability of the slope regreening structure and increasing the greening rate of slope support.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0044] Embodiment 1:

[0045] Combination Figures 1 to 10 As shown, this embodiment is a structure for regreening a supported rock slope, including a drip irrigation pipe 3, a plurality of planting holes 1, a plurality of planting frames 4 and an adjustment component 6. The drip irrigation pipe 3 is installed on the bedrock surface of the slope via a fixing member. The drip irrigation pipe 3 is arranged in a grid shape. The drip irrigation pipe 3 is used to irrigate the green plants on the slope and provide support for the green plants to grow and attach to. A plurality of planting holes 1 are provided on the bedrock surface of the slope, and the planting holes 1 correspond to the pipe nodes of the drip irrigation pipe 3. Small shrubs 2 are planted inside the planting holes 1. A plurality of planting frames 4 are provided on the surface of the slope, and the planting frames 4 correspond to the grids of the drip irrigation pipe 3. Climbing plants are planted inside the planting frames 4. An adjustment component 6 is provided inside the drip irrigation pipe 3, and the adjustment component 6 can control the irrigation object of the drip irrigation pipe 3.

[0046] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the drip irrigation pipe 3 includes a transverse connecting pipe 5, a vertical connecting pipe 8 and a node connecting pipe 7. The transverse connecting pipe 5 and the vertical connecting pipe 8 are both circular pipes. The node connecting pipe 7 includes elbows, tees, crosses and other specifications. The transverse connecting pipe 5 and the vertical connecting pipe 8 are spliced ​​through the node connecting pipe 7 to form the drip irrigation pipe 3. Specifically, in this embodiment, the drip irrigation pipe 3 is provided with a water delivery port at the top of the slope. The drip irrigation pipe 3 is connected to an external water supply device through the water delivery port, and water can be supplied to the inside of the drip irrigation pipe 3 through the external water supply device.

[0047] Further, such as Figure 3 As shown, two rows of drip irrigation holes 11 are axially arranged on the transverse connecting pipe 5 of the drip irrigation pipe 3, and the two rows of drip irrigation holes 11 are oriented toward the planting hole 1 and the forward slope, so that they correspond to the planting hole 1 and the planting frame 4 respectively. The regulating component 6 controls the opening and closing of the drip irrigation holes 11 to adjust the drip irrigation pipe 3 to irrigate the small shrubs 2 or climbing plants.

[0048] In some embodiments, such as Figures 6 to 9 As shown, the adjustment assembly 6 includes a horizontal rotating shaft 12, a rotating ring 14, a bevel gear 13, a vertical rotating shaft 9 and a motor. The horizontal rotating shaft 12 is rotatably arranged in the horizontal connecting pipe 5 of the drip irrigation pipe 3. A plurality of rotating rings 14 are arranged at intervals on the horizontal rotating shaft 12. The rotating rings 14 fit the inner wall of the horizontal connecting pipe 5. The spacing of the rotating rings 14 corresponds to the spacing of the drip irrigation holes 11. The rotating ring 14 is provided with an adjustment hole 15 corresponding to the drip irrigation hole 11. The adjustment hole 15 is consistent in size with the drip irrigation hole 11. The end of the horizontal rotating shaft 12 is connected to the bevel gear 13. The vertical rotating shaft 9 is rotatably 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 mesh with the bevel gears 13 of the horizontal rotating shaft 12. The output end of the motor is connected to the end of the vertical rotating shaft 9 through a flat gear set.

[0049] Furthermore, in this embodiment, for the clamping cooperation between the transverse part of the adjustment component 6 and the horizontal section of the drip irrigation pipe 3, the first clamping form is: the inner wall of the horizontal section of the drip irrigation pipe 3 is provided with a plurality of sliding grooves at intervals along the axial direction, and the swivel 14 is rotatably clamped in the sliding groove, and the sliding groove can horizontally limit the swivel 14 to ensure that the adjustment hole 15 on the swivel 14 and the drip irrigation hole 11 on the drip irrigation pipe 3 are not misaligned with each other. The second clamping form is: the inner walls of the vertical connecting pipes 8 on both sides of the drip irrigation pipe 3 are provided with limiting grooves, the outermost end of the transverse shaft 12 extends and is clamped in the limiting groove, and the end of the transverse shaft 12 is rotatably connected to the limiting groove, so that the limiting groove can horizontally limit the transverse shaft 12 without affecting the natural rotation of the transverse shaft 12.

[0050] Furthermore, in this embodiment, since the horizontal rotating shaft 12 and the vertical rotating shaft 9 are meshed with each other through the bevel gear 13, the adjustment component 6 can be arranged in a variety of ways in the drip irrigation pipe 3. Specifically, the first arrangement is as follows: Fig.10As shown, a plurality of single-stage transverse connecting tubes 5 are connected to form a row of transverse connecting tubes 5, and a group of transverse rotating shafts 12 and corresponding rotating rings 14 are installed in each of the plurality of single-stage transverse connecting tubes 5. Both ends of the transverse rotating shafts 12 in the single-stage transverse connecting tubes 5 are provided with bevel gears 13, and the transverse rotating shafts 12 in the plurality of rows of transverse connecting tubes 5 are distributed in an array. A vertical connecting tube 8 is connected at the connection point of the plurality of single-stage transverse connecting tubes 5, and a vertical rotating shaft 9 and a corresponding bevel gear 13 are installed in each of the vertical connecting tubes 8. The vertical rotating shafts 9 in the vertical connecting tubes 8 on both sides of the outermost sides of the drip irrigation pipe 3 are connected to the bevel gears 13 on the transverse rotating shafts 12 in the transverse connecting tubes 5 through a single-side meshing transmission connection, and the vertical rotating shafts 9 in the vertical connecting tubes 8 in the middle of the drip irrigation pipe 3 are connected to the bevel gears 13 on the transverse rotating shafts 12 in the adjacent transverse connecting tubes 5 on both sides through a bevel gear 13. The output end of the motor is connected to the end of any vertical rotating shaft 9 through a flat gear set.

[0051] The vertical rotating shaft 9 is driven to rotate by a motor via a flat gear set. Due to the mutual meshing of the bevel gears 13, in this arrangement, the rotating rings 14 in the transverse connecting pipes 5 of adjacent sections rotate in opposite directions.

[0052] Specifically, the second arrangement form is that a plurality of single-stage transverse connecting tubes 5 are connected to form a row of transverse connecting tubes 5. Different from the first arrangement form, only one set of transverse rotating shafts 12 is installed inside the single row of transverse connecting tubes 5. The first end of the transverse rotating shaft 12 is connected to a bevel gear 13. The second end of the transverse rotating shaft 12 is clamped and rotatably connected to the limit groove. The transverse rotating shafts 12 in the multiple rows of transverse connecting tubes 5 are distributed in an array. The vertical connecting tube 8 in the middle position is connected to the connection point of the transverse connecting tube 5. The vertical rotating shaft 9 and the corresponding rotating ring 14 are not arranged in this part of the vertical connecting tube 8. The vertical rotating shaft 9 is only installed in the vertical connecting tube 8 on the outermost side. A plurality of bevel gears 13 are arranged on the vertical rotating shaft 9 along the axial direction. The bevel gears 13 on the vertical rotating shaft 9 are correspondingly engaged with the bevel gears 13 at the ends of the plurality of transverse rotating shafts 12 on one side. The output end of the motor is connected to the end of the vertical rotating shaft 9 through a flat gear set.

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

[0054] Furthermore, the planar gear set includes a first planar gear and a second planar gear. The output end of the motor is connected to the first planar gear, and the end of the vertical shaft 9 is connected to the second planar gear. The first planar gear and the second planar gear are meshed with each other, so that the vertical shaft 9 can rotate around its own axis through the motor drive.

[0055] In some embodiments, the planting hole 1 is drilled by dry drilling. When the slope stability is good, water drilling is used. If the planting hole 1 is located in the crack of the rock slope, the drilling depth only penetrates the sprayed concrete layer on the slope surface. Specifically, the drilling angle is tilted downward, and the diameter and depth of the drilling hole are determined according to the root growth diameter and length of the small shrub plant 2.

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

[0057] Furthermore, the climbing plant seeds are selected from climbing plants with aerial roots such as creeping ivy.

[0058] Furthermore, 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 small shrubs 2 and the climbing plants.

[0059] In some embodiments, the fixings include steel wire ropes and cement nails. The cement nails penetrate the sprayed concrete layer on the slope surface, are anchored into the bedrock surface of the slope, and cooperate with the steel wire ropes to fix the drip irrigation pipe 3 to the slope surface.

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

[0061] By laying drip irrigation pipes 3 on the slope, planting holes 1 are set at the nodes of the drip irrigation pipes 3, planting frames 4 are set in the grid of the drip irrigation pipes 3, small shrubs 2 are planted in the planting holes 1, and climbing plants are planted in the planting frames 4, and finally a greening structure of "small shrubs 2-drip irrigation pipes 3-climbing plants" is formed. This greening structure has good compatibility with the existing rock slope support method of "anchor rods-keel bars-wire mesh-sprayed concrete layer". Through the method of simultaneous design and construction, the length of some anchor rods can be increased to enhance the integrity of the support structure and the greening structure. It can also be possible to use the method of reserved drilling holes to avoid repeated construction and reduce the cost.

[0062] First, the drip irrigation pipe 3 is fixed to the bedrock surface of the slope by cement steel nails and steel wire ropes, so that the load of the greening structure is transferred to the bedrock surface, which enhances the effect of the combination of the shotcrete layer and the bedrock surface. After the small shrub plant 2 grows up, the rhizome of the small shrub plant 2 can provide good support for the drip irrigation pipe 3. The drip irrigation pipe 3 covering the surface of the slope is convenient for the vines of climbing plants to grow and attach. After the climbing plants grow, the climbing plant roots, the drip irrigation pipe 3, and the cement steel nails are subjected to overall force, which can effectively improve the safety of the overall structure, reduce damage and wear of components, and reduce maintenance and repair costs. If the planting soil and the roots of climbing plants are filled in the original slope cracks, the stability of the slope can also be enhanced.

[0063] Secondly, the adjustment component 6 can be used to adjust the drip irrigation pipe 3 to irrigate the small shrubs 2 or climbing plants. Among them, the vertical shaft 9 is driven to rotate by the motor through the flat gear set. Since the bevel gear 13 on the vertical shaft 9 and the bevel gear 13 on the horizontal shaft 12 are meshed with each other, the horizontal shaft 12 is driven by the vertical shaft 9 to rotate around its own axis, and the horizontal shaft 12 drives the swivel 14 to rotate in the sliding groove, so that the adjustment hole 15 on the swivel 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 shrubs 2 in the planting hole 1 or the climbing plants in the planting frame 4. When the adjustment hole 15 on the swivel 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 self-clean the inside of the pipe.

[0064] At the same time, the grid structure formed by the drip irrigation pipe 3 can be regarded as a multi-level waterfall, which can slow down the water flow rate, provide sufficient time for climbing plants to absorb water, and is conducive to the absorption of climbing plants. The drip irrigation pipe 3 is used to enhance the durability of the greening structure, and the branches and leaves of climbing plants can cover and cover the drip irrigation pipe 3, ensuring the beautiful effect of slope greening, and climbing plants have fewer diseases and pests, and the maintenance cost is also low.

[0067] On the slope surface, planting holes 1 are arranged by dry drilling method;

[0071] The climbing plant planting soil is sprayed in the planting frame 4 .
