Description

Technical Field

[0001] This invention belongs to the field of vegetation ecological restoration technology in karst areas, specifically relating to an ecological restoration system and method for steep slope rock masses with large dip angles in southwestern karst areas. Background Technology

[0002] Karst regions are mainly concentrated in southwestern my country. Hydroseeding and slope protection are common methods for vegetation restoration. However, for steep, high-slope rock masses, the large slope results in low water retention capacity and poor drought resistance of the hydroseeded soil, making it difficult for plants to survive. Although irrigation equipment can be used to maintain soil moisture, the poor water retention capacity of the soil on steep slopes necessitates frequent irrigation, leading to high maintenance costs. In particular, the hydroseeded soil layer is easily affected by irrigation, making it prone to erosion and hindering the maintenance of a suitable environment for plant growth. Slope protection construction is extensive and costly, and slope protection bricks are unsuitable for steep rock surfaces due to the risk of landslides. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides an ecological restoration system and method for steep, high-angle rock masses in karst areas of Southwest China, solving the problems of poor soil stabilization and moisture retention and high construction costs in existing ecological restoration methods for steep, high-angle rock masses.

[0004] In a first aspect, the present invention proposes an ecological restoration system for steep, high-slope rock masses in karst areas of Southwest China, comprising: a first water supply device, a second water supply device, anchors, a suspended water supply assembly, planting baskets, fillers, and seedlings; the first water supply device is located at the top of the rock mass; the second water supply device is located at the bottom of the rock mass; multiple planting baskets are suspended from the suspended water supply assembly, and the suspended water supply assembly with the planting baskets is laid on the rock surface of the rock mass; the upper end of the suspended water supply assembly extends to the top of the rock mass and is connected to the first water supply device, and the lower end of the suspended water supply assembly extends to the bottom of the rock mass and is connected to the second water supply device; the anchors anchor the suspended water supply assembly extending to the top of the rock mass; the suspended water supply assembly includes an integrated jacket and a steel wire rope and a water supply pipe inserted within the integrated jacket; the water supply pipe is connected to a branch pipe, the end of which extends into the planting basket. The planting basket includes a V-shaped basket and clamps hinged to both sides of the V-shaped basket. The V-shaped basket is suspended between two suspended water supply components via the clamps on both sides. A V-shaped groove is horizontally formed on the rock surface, and the bottom of the V-shaped basket is inserted into the V-shaped groove. The V-shaped basket includes a double-layer V-shaped mesh structure and side plates on both sides of the double-layer V-shaped mesh structure. The double-layer V-shaped mesh structure includes an outer V-shaped mesh and an inner V-shaped mesh, with a V-shaped space formed between the outer and inner V-shaped meshes. The filler includes a sponge layer, a nutrient soil layer, a granular layer, and a gravel layer. The gravel layer fills the V-shaped space. The sponge layer, nutrient soil layer, and granular layer fill the internal space of the inner V-shaped mesh from bottom to top. The height of the sponge layer is greater than or equal to the depth of the V-shaped groove. Planting holes are provided in the nutrient soil layer, passing through the granular layer, and the seedlings are planted in the planting holes.

[0005] Furthermore, the clamp suspension component includes a ball-head hinge, an L-shaped boom, and a clamp component connected in sequence; the clamp component is connected to the integral clamp clamp; and the ball-head hinge is connected to the side plate.

[0006] Furthermore, the clamping component includes a first clamping plate, a second clamping plate, and two sets of connecting members; the first clamping plate and the second clamping plate clamp the upper and lower ends of the integrated clamp; the first clamping plate is connected to the L-shaped boom; the two sets of connecting members respectively connect the two ends of the first clamping plate and the second clamping plate.

[0007] Furthermore, each set of the tie-in components includes an L-shaped limiting pin and a tie rope. The L-shaped limiting pin is disposed at one end of the second hoop that is opposite to the integral sleeve. One end of the tie rope is connected to the first hoop, and the other end is connected to a tie ring. The tie ring is used to be fitted onto the L-shaped limiting pin.

[0008] Furthermore, the water supply pipe is provided with multiple metal taps at intervals along its length, and the metal taps are connected to plugs or branch pipes; the tie rope is wrapped around the metal taps at least once.

[0009] Furthermore, the integrated jacket includes a fixed sleeve and C-shaped tubes disposed on one or both sides of the fixed sleeve; the C-shaped tubes are provided with openings; the wire rope is inserted into the fixed sleeve and is fixedly connected to the fixed sleeve; the water supply pipe is inserted into the C-shaped tubes, and the metal tap extends out from the openings.

[0010] Furthermore, the metal tap is provided with a threaded section, and the plug or the branch pipe is threadedly connected to the metal tap.

[0011] Furthermore, each set of the tie members includes multiple L-shaped limiting pins and multiple tie rings connected to the same tie rope, with the multiple tie rings being fitted one-to-one onto the multiple L-shaped limiting pins.

[0012] Furthermore, the branch pipe extends into the V-shaped space, passes through the inner V-shaped mesh, and extends into the nutrient soil layer.

[0013] Secondly, this invention also proposes an ecological restoration method for steep, high-slope rock masses in karst areas of southwestern China, comprising the following steps:

[0014] The first water supply device is installed at the top of the rock mass; the second water supply device is installed at the bottom of the rock mass.

[0015] Multiple planting baskets are suspended on a suspended water supply assembly; the suspended water supply assembly includes an integrated jacket and a steel wire rope and a water supply pipe inserted in the integrated jacket; the water supply pipe is connected to a branch pipe, the end of which extends into the planting basket;

[0016] The upper end of the suspended water supply assembly extends to the top of the rock mass and is connected to the first water supply device; the lower end of the suspended water supply assembly extends to the bottom of the rock mass and is connected to the second water supply device.

[0017] The suspended water supply assembly extending to the top of the rock mass is anchored using anchors;

[0018] Construction workers wear safety belts, attach the safety rope hooks connected to the safety belts to the suspended water supply assembly, and descend along the suspended water supply assembly to the target position; a transverse V-shaped groove is opened on the rock surface at the target position;

[0019] Slide the planting basket along the suspended water supply assembly so that the bottom of the planting basket is inserted into the V-shaped groove; the planting basket includes a V-shaped basket and clamp suspension members hinged to both sides of the V-shaped basket; adjust the tilt angle of the V-shaped basket so that only the bottom of the V-shaped basket contacts the rock mass, while the rest of the basket remains at a distance from the rock mass;

[0020] From bottom to top, a sponge layer, a nutrient soil layer, and a granular layer are filled into the V-shaped basket; the height of the sponge layer is greater than or equal to the depth of the V-shaped groove; planting holes that pass through the granular layer are set in the nutrient soil layer, and seedlings are planted in the planting holes;

[0021] After the installation of all the planting baskets on the suspended water supply assembly is completed, the construction workers descend to the bottom of the rock mass along the suspended water supply assembly and release the safety rope hook;

[0022] Water is periodically supplied to the planting basket using the first water supply device and the second water supply device.

[0023] The beneficial effects of this invention are as follows: Planting baskets are suspended and laid on steeply sloping rock surfaces using a suspended water supply system. Seedlings are planted inside the baskets, and the suspended water supply system provides regular watering, improving the survival rate of the seedlings. Compared to traditional slope protection brick construction methods, the planting baskets will not tip over, and compared to traditional topsoil spraying methods, the filler material is less prone to loss. The planting baskets of this invention are V-shaped, and their interiors are filled from bottom to top with a sponge layer, a nutrient soil layer, and a granular layer. The granular layer prevents the nutrient soil layer from floating and being lost, and the water-retaining capacity of the sponge layer prolongs the moisture cycle of the nutrient soil layer, reducing the frequency of irrigation. The V-shaped basket employs a double-layer V-shaped mesh structure, consisting of an outer and inner V-shaped mesh. The gravel layer filling the V-shaped space acts as a soil stabilizer, preventing the overflow and loss of the nutrient soil and granular layers. The double-layer V-shaped mesh structure and gravel layer also provide conditions for plant roots to climb, enhancing the plant's wind resistance. The bottom of the V-shaped basket is inserted into a horizontally carved V-shaped groove on the rock surface, with only the bottom in contact with the rock. This prevents rainwater flowing down the rock surface from washing away the nutrient soil and granular layers, while ensuring the sponge layer fully absorbs rainwater, resulting in excellent soil stabilization and water retention. Simultaneously, the good aeration of the nutrient soil layer promotes root growth. The suspended water supply component contains internal steel wire ropes that can be used as traction ropes. Construction workers can use these ropes, anchored to the rock, to descend and perform operations such as V-shaped groove construction, basket installation, and seedling planting. This is simple, efficient, and facilitates later maintenance of the baskets and replanting. Furthermore, the steel wire ropes are interwoven within an integrated sleeve, preventing them from rusting and corroding. This invention involves creating a V-shaped groove at the target location on the rock surface. Compared to the traditional method of constructing steps on the rock surface, this method requires less work, is more convenient, and has lower construction costs. The V-shaped basket is suspended from the suspended water supply assembly via clamps hinged on both sides. The tilt angle of the V-shaped basket can be adjusted using ball-head hinges to adapt to the slope of the rock surface. The clamps can be quickly installed and removed from the integrated clamp using tie-down connectors. The V-shaped basket can slide along the integrated clamp to the target position via the clamps, making installation labor-saving and efficient. The tie rope is wrapped around the metal tap at least once to secure the tie rope, preventing the tie ring from detaching from the L-shaped limit pin, ensuring the stability of the V-shaped basket installation, and also limiting the sliding of the V-shaped basket. The metal tap also serves as a step-by-step positioning mechanism, preventing the V-shaped basket from sliding too far from the target position and affecting installation efficiency.

Detailed Implementation

[0033] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] like Figures 1-8 As shown in the figure, the ecological restoration system for steep slope rock masses in the karst region of Southwest China in this embodiment includes: a first water supply device 1, a second water supply device 2, anchors 3, a suspended water supply assembly 4, a planting basket 5, filler material, and seedlings 6. The seedlings 6 can be honeysuckle seedlings.

[0035] The first water supply device 1 is located at the top of the rock mass 7; the second water supply device 2 is located at the bottom of the rock mass 7.

[0036] The upper end of the suspended water supply component 4 extends to the top of the rock mass 7 and is connected to the first water supply device 1. The lower end of the suspended water supply component 4 extends to the bottom of the rock mass 7 and is connected to the second water supply device 2. The anchor 3 anchors the suspended water supply component 4 extending to the top of the rock mass 7. The anchor 3 uses a commonly used anchor rod. The bottom of the anchor rod is inserted into the rock mass 7, and the top of the anchor rod is provided with a cylinder. The side wall of the cylinder is provided with a spiral groove. The suspended water supply component 4 is wound around the spiral groove at least once and is tightened and fixed to the cylinder with bolts. The bolts tighten the steel wire rope 10 of the suspended water supply component 4.

[0037] Both the first water supply device 1 and the second water supply device 2 include a water tank and a water pump. The water tank of the first water supply device 1, located at the top of the rock mass 7, can also be connected to the municipal water supply network to supply water to the tank at the top of the rock mass 7. The water tank of the second water supply device 2 is embedded in the bottom of the rock mass 7, with its top surface lower than the ground level, to collect rainwater, especially rainwater flowing down the slope of the rock mass 7. The water pump of the first water supply device 1 pumps water from the water tank at the top of the rock mass 7 to the water supply pipes 11 of each suspended water supply component 4. The water in the water supply pipes 11 irrigates the filler material in the planting basket 5, and excess water flows along the water supply pipes 11 to the water tank of the second water supply device 2. The water pump of the second water supply device 2 pumps water from the water tank at the bottom of the rock mass 7 to the water supply pipes 11 of each suspended water supply component 4, and excess water flows back to the water tank of the first water supply device 1. The ecological restoration system also includes a controller, a humidity sensor, and a water level sensor. The humidity sensor is installed inside the planting basket 5 to monitor the humidity of the filler material. Water level sensors are installed in the water tanks of the first water supply device 1 and the second water supply device 2. When the humidity is lower than a preset threshold, the controller starts the water pump in the tank with the higher water level based on the water level information from the water level sensor. Of course, since the volume of the water tank is fixed, the volume of water in the tank can be calculated from the water level information. Since the number of planting baskets 5 is known, the volume of water required to irrigate all planting baskets 5 is also known. When it is determined from the water level information that the water in the tank is insufficient to irrigate all planting baskets 5, the valve connecting to the municipal water supply network can be opened to supply water to the water tank of the first water supply device 1.

[0038] Multiple planting baskets 5 are suspended from the suspended water supply component 4, and the suspended water supply component 4 with the planting baskets 5 is laid on the rock surface 8 of the rock mass 7. The number and density of the planting baskets 5 are determined according to the area of ​​the rock surface 8 that needs ecological restoration. Preferably, 5-10 seedlings 6 are planted per square meter. After the number and density of the planting baskets 5 are determined, the target position of each seedling 6 is determined on the rock surface 8, and the distribution position of the suspended water supply component 4 and the location of the V-shaped groove 13 are determined accordingly.

[0039] The suspended water supply assembly 4 includes an integrated jacket 9 and a steel wire rope 10 and a water supply pipe 11 inserted inside the integrated jacket 9; the water supply pipe 11 is connected to a branch pipe 32, and the end of the branch pipe 32 extends into the planting basket 5; the integrated jacket 9 serves to protect the steel wire rope 10 and the water supply pipe 11.

[0040] The planting basket 5 includes a V-shaped basket and clamp suspension components 12 hinged to both sides of the V-shaped basket; the V-shaped basket is suspended between two suspended water supply components 4 by the clamp suspension components 12 on both sides; a V-shaped groove 13 is opened horizontally on the rock surface 8, and the bottom of the V-shaped basket is inserted into the V-shaped groove 13.

[0041] The V-shaped basket includes a double-layer V-shaped mesh structure and side plates 14 disposed on both sides of the double-layer V-shaped mesh structure. The double-layer V-shaped mesh structure includes an outer V-shaped mesh 15 and an inner V-shaped mesh 16 maintaining a distance to form a V-shaped space. The mesh diameters of the outer V-shaped mesh 15 and the inner V-shaped mesh 16 are different, with the mesh diameter of the outer V-shaped mesh 15 being larger than that of the inner V-shaped mesh 16.

[0042] The filling material includes a sponge layer 17, a nutrient soil layer 18, a granular layer 19, and a gravel layer 20; the gravel layer 20 fills the V-shaped space; the sponge layer 17, nutrient soil layer 18, and granular layer 19 are filled sequentially from bottom to top within the inner V-shaped mesh 16; the height of the sponge layer 17 is greater than or equal to the depth of the V-shaped groove 13; planting holes are provided in the nutrient soil layer 18, passing through the granular layer 19, and seedlings 6 are planted in the planting holes. The granular layer 19 is a mixture of fine coconut coir, coarse coconut husk, and perlite in a 5:3:2 ratio. The nutrient soil layer 18 can directly use existing conventional nutrient soil. The nutrient soil layer 18 can be adjusted according to the type of seedling 6. The particle size of the gravel layer 20 is between 10-20 mm. The sponge layer 17 is triangular prism-shaped and horizontally set at the bottom of the inner V-shaped mesh 16.

[0043] like Figure 4 , Figure 5 As shown, the clamp suspension component 12 includes a ball-head hinge 21, an L-shaped boom 22, and a clamp component connected in sequence; the clamp component is connected to the integrated clamp sleeve 9; the ball-head hinge 21 is connected to the side plate 14. Under the action of the ball-head hinge, the L-shaped boom 22 can rotate relative to the side plate 14, thereby adjusting the relative angle between the clamp component and the side plate 14, thus realizing the adjustment of the tilt angle of the V-shaped basket.

[0044] The clamping component includes a first clamping plate 23, a second clamping plate 24, and two sets of tie rods; the first clamping plate 23 and the second clamping plate 24 clamp the upper and lower ends of the integrated clamping sleeve 9, with the first clamping plate 23 located at the lower end of the integrated clamping sleeve 9 and the second clamping plate 24 located at the upper end of the integrated clamping sleeve 9; the first clamping plate 23 is connected to the L-shaped boom 22; the two sets of tie rods respectively tie the ends of the first clamping plate 23 and the second clamping plate 24, and the two sets of tie rods, the first clamping plate 23, and the second clamping plate 24 are closed to form a closed ring structure surrounding the integrated clamping sleeve 9.

[0045] Each set of tie members includes an L-shaped limiting pin 25 and a tie rope 26. The L-shaped limiting pin 25 is located at one end of the second hoop 24 facing away from the integrated sleeve 9. One end of the tie rope 26 is connected to the first hoop 23, and the other end is connected to a tie ring 27. The tie ring 27 is used to be fitted onto the L-shaped limiting pin 25.

[0046] like Figure 7 , Figure 8 As shown, multiple metal taps 28 are spaced apart along the length of the water supply pipe 11. Each metal tap 28 is connected to a plug 33 or a branch pipe 32. A tie rope 26 is wrapped around the metal tap 28 at least once. The integrated jacket 9 includes a fixed sleeve 29 and C-shaped pipes 30 disposed on both sides of the fixed sleeve 29. An opening 31 is provided on the C-shaped pipe 30. A steel wire rope 10 is inserted into the fixed sleeve 29 and is fixedly connected to the fixed sleeve 29. The water supply pipe 11 is inserted into the C-shaped pipe 30, and the metal taps 28 protrude from the opening 31.

[0047] The metal connector 28 is provided with a threaded section, and the plug 33 or branch pipe 32 is threadedly connected to the metal connector 28. Before installing the planting basket 5, each metal connector 28 is threadedly connected to a plug 33. After the planting basket 5 is placed on the V-groove 13 at the target location, the plug 33 on the metal connector 28 near the planting basket 5 is unscrewed, the branch pipe 32 is connected to the metal connector 28, and the other end of the branch pipe 32 is inserted into the V-shaped space inside the planting basket 5, passing through the inner V-shaped mesh 16 and extending into the nutrient soil layer 18. The metal connectors 28 in the remaining areas where the planting basket 5 is not installed are still sealed by the plug 33.

[0048] In some embodiments, each set of tie members includes two L-shaped limiting pins 25 and two tie loops 27 connected to the same tie rope 26, with the two tie loops 27 fitted one-to-one onto the two L-shaped limiting pins 25. Since two tie loops 27 are provided on the same tie rope 26 and fitted onto the two L-shaped limiting pins 25 respectively, the risk of both tie loops 27 falling off the L-shaped limiting pins 25 at the same time is low.

[0049] When the two clamps on both sides of the V-shaped basket are respectively clamped to the outside of the integrated sleeve 9, the V-shaped basket is in a suspended state and can slide along the length of the integrated sleeve 9. When it encounters the metal tap 28, the sliding is blocked. At this time, the tie ring 27 needs to be manually moved over the metal tap 28 before it can continue to slide. This is to avoid the V-shaped basket sliding too far away from the target position, or the sliding speed increasing and causing a collision that will cause damage.

[0050] Based on the same inventive concept, this invention also proposes an ecological restoration method for steep, high-slope rock masses in karst areas of Southwest China. Based on the aforementioned ecological restoration system, the method includes the following steps:

[0051] Step 1: Install the first water supply device 1 on the top of the rock mass 7; install the second water supply device 2 on the bottom of the rock mass 7.

[0052] Step 2: Based on the area of ​​rock surface 8 that needs ecological restoration, determine the distribution location of the suspended water supply components 4 and the location of the V-shaped groove 13, arrange the suspended water supply components 4, and suspend the required number of planting baskets 5 on the suspended water supply components 4.

[0053] Step 3: Extend the upper end of the suspended water supply component 4 to the top of the rock mass 7 and connect it to the first water supply device 1; extend the lower end of the suspended water supply component 4 to the bottom of the rock mass 7 and connect it to the second water supply device 2.

[0054] Step 4: Anchor the suspended water supply assembly 4, which extends to the top of the rock mass 7, using anchor 3.

[0055] Step 5: The construction workers put on safety belts, attach the safety rope hook connected to the safety belt to the suspended water supply component 4, and descend from the top of the rock mass 7 along the suspended water supply component 4 to the nearest target position.

[0056] Step 6: Create a transverse V-shaped groove 13 on the rock surface 8 at the target location; slide the planting basket 5 on the suspended water supply assembly 4 along the suspended water supply assembly 4, so that the bottom of the uppermost planting basket 5 on the suspended water supply assembly 4 is inserted into the V-shaped groove 13 at the target location; adjust the tilt angle of the V-shaped basket so that only the bottom of the V-shaped basket contacts the rock mass 7, while the rest of the basket remains at a distance from the rock mass 7; fill the V-shaped basket with a sponge layer 17, a nutrient soil layer 18, and a granular layer 19 from bottom to top; the height of the sponge layer 17... The depth of the V-groove 13 is greater than or equal to the depth of the nutrient soil layer 18; planting holes are set inside the nutrient soil layer 18, passing through the granular layer 19, and the seedlings 6 are planted in the planting holes; the gravel layer 20 is filled into the V-shaped space between the outer V-shaped mesh 15 and the inner V-shaped mesh 16; the plug 33 on the metal connector 28 near the planting basket 5 is unscrewed; the branch pipe 32 is connected to the metal connector 28; and the other end of the branch pipe 32 is inserted into the V-shaped space inside the planting basket 5, passing through the inner V-shaped mesh 16 and extending into the nutrient soil layer 18. This completes the installation of the planting basket 5 and the planting of the seedlings 6 at a target location.

[0057] Step 7: The construction workers continue to descend to the next nearest target location and return to Step 6.

[0058] Step 8: Repeat steps 6 and 7 above until the planting basket 5 at the target location on the path of the suspended water supply component 4 is installed and the seedlings 6 are planted. The construction workers then descend along the suspended water supply component 4 to the bottom of the rock mass 7 and release the safety rope hooks. Multiple construction workers can work simultaneously, with one worker assigned to each suspended water supply component 4.

[0059] Step 9: Based on the humidity of the filling material, use the first water supply device 1 and the second water supply device 2 to periodically supply water to the planting basket 5.

[0060] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
