[0002] Karst areas are mainly concentrated in the southwestern region of China. Soil spraying and slope protection construction are common methods for vegetation ecological restoration. However, for large dip angle and high steep slope rock masses, due to the large slope of the rock surface, the water storage capacity of the sprayed soil is low and the drought resistance is poor, resulting in difficulty for the planted plants to survive. Although in related technologies, irrigation equipment can be used to maintain soil moisture, the water storage capacity of the soil on high steep slopes is poor, and frequent irrigation is required, leading to high later maintenance costs. In particular, the soil layer of the sprayed soil will be affected by irrigation, and the soil layer is prone to erosion, making it difficult to maintain the plant growth environment.

[0014] Install the first water supply device at the top of the rock mass; install the second water supply device at the bottom of the rock mass;

[0015] Suspend a plurality of planting baskets on the suspended water supply assembly; the suspended water supply assembly includes an integral jacket and a steel wire rope and a water supply pipe inserted into the integral jacket; the water supply pipe is communicated with a branch pipe, and the end of the branch pipe extends into the planting basket;

[0016] Extend the upper end of the suspended water supply assembly to the top of the rock mass and communicate it with the first water supply device; extend the lower end of the suspended water supply assembly to the bottom of the rock mass and communicate it with the second water supply device;

[0017] Anchore the suspended water supply assembly extending to the top of the rock mass by using anchor fittings;

[0018] The construction workers wear safety belts, hang the buckle of the safety rope connected to the safety belt on the suspended water supply assembly, and descend along the suspended water supply assembly to the target position; open a horizontal V-shaped groove 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 hoop suspension members hinged on both sides of the V-shaped basket; adjust the inclination angle of the V-shaped basket so that only the bottom of the V-shaped basket contacts the rock mass, and the rest of the parts are kept at a distance from the rock mass;

[0020] Fill the V-shaped basket with a sponge layer, a nutrient soil layer and a granular layer in sequence from bottom to top; the height of the sponge layer is greater than or equal to the depth of the V-shaped groove; set planting holes passing through the granular layer in the nutrient soil layer, and plant the seedlings in the planting holes;

[0021] After installing all the planting baskets on the suspended water supply assembly, the construction personnel descend along the suspended water supply assembly to the bottom of the rock mass and release the buckle of the safety rope;

[0022] Use the first water supply device and the second water supply device to supply water to the planting basket regularly.

[0023] The beneficial effects of the present invention are as follows: The planting basket is paved on the large-inclination rock surface by means of the suspended water supply component, and the planting seedlings are planted in the planting basket. The suspended water supply component is used for regular water supply to improve the survival rate of the planting seedlings. Compared with the traditional slope protection brick construction method, the planting basket will not tip over. Compared with the traditional soil spraying method, the filling material is not easy to lose. The planting basket of the present invention adopts a V-shaped basket, which is internally filled with a sponge layer, a nutrient soil layer and a granular layer in sequence from bottom to top. The granular layer can prevent the nutrient soil layer from floating and flowing away. The water storage capacity of the sponge layer can extend the humidity cycle of the nutrient soil layer and reduce the number of watering times. The V-shaped basket adopts a double-layer V-shaped net structure composed of an outer V-shaped net and an inner V-shaped net. The gravel layer filled in the V-shaped space plays a role in soil fixation and prevents the nutrient soil layer and the granular layer from overflowing and flowing away. The double-layer V-shaped net structure and the gravel layer also provide conditions for the plant roots to climb and improve the wind resistance of the plants. The bottom of the V-shaped basket is inserted into the V-shaped groove horizontally opened on the rock surface, and only the bottom contacts the rock surface. Thus, the rainwater flowing down along the rock surface will not wash the nutrient soil layer and the granular layer, and it can ensure that the sponge layer fully absorbs the rainwater, having a good soil fixation and water conservation effect. At the same time, the nutrient soil layer has good air permeability, which is beneficial to the growth of the roots. The internal of the suspended water supply component is provided with a steel wire rope, which can be used as a construction traction rope. Construction workers can descend along the steel wire rope anchored on the rock mass and carry out operations such as V-shaped groove construction, planting basket installation, and planting seedling planting, which is simple and efficient, and is also conducive to the later maintenance of the planting basket and the replanting of the planting seedlings. Moreover, the steel wire rope is inserted into the integrated clamp sleeve, and the steel wire rope is not easy to rust and corrode. The present invention opens a V-shaped groove at the target position on the rock surface. Compared with the traditional method of constructing steps on the rock surface, the engineering quantity is small, the construction is convenient, and the construction cost is low. The V-shaped basket is suspended on the suspended water supply component by the hoop suspension parts hinged on both sides thereof, and the inclination angle of the V-shaped basket can be adjusted through the ball head hinge parts to adapt to the rock surface slope. The hoop parts can be quickly installed and disassembled on the integrated clamp sleeve through the tie parts. The V-shaped basket can slide along the integrated clamp sleeve to the target position through the hoop parts, and the installation is labor-saving and efficient. The tie rope is wound around the metal splice head for at least one circle, which can fasten the tie rope, prevent the tie ring from disengaging from the L-shaped limit pin, ensure the stable installation of the V-shaped basket, and at the same time can also limit the sliding of the V-shaped basket. The metal splice head can also play a role in step-by-step positioning, preventing the V-shaped basket from sliding too far away from the target position and affecting the installation efficiency.

Detailed implementation manners

[0033] The following further describes the present application in detail with reference to the accompanying drawings and specific embodiments:

[0034] As Figures 1 - 8 shown, the large dip angle and high steep slope rock mass ecological restoration system in the southwestern karst area of this embodiment includes: a first water supply device 1, a second water supply device 2, an anchor 3, a suspended water supply assembly 4, a planting basket 5, a filler, and planted seedlings 6. The planted seedlings 6 can be honeysuckle seedlings.

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

[0036] The upper end of the suspended water supply assembly 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 assembly 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 assembly 4 that extends to the top of the rock mass 7. The anchor 3 uses a commonly used existing bolt. The bottom of the bolt is inserted into the rock mass 7, and a cylinder is provided at the top of the bolt. A spiral groove is provided on the side wall of the cylinder. The suspended water supply assembly 4 is wound around the spiral groove for at least one turn and is fixed on the cylinder by using a bolt. The bolt presses the steel wire rope 10 of the suspended water supply assembly 4.

[0037] Both the first water supply device 1 and the second water supply device 2 include a water tank and a water pump. Among them, 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 pipe network for supplying water into the water 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, and its top surface is lower than the ground for collecting rainwater, especially the rainwater flowing down from the slope of the rock mass 7. The water pump of the first water supply device 1 is used to pump the water in the water tank at the top of the rock mass 7 into the water supply pipes 11 of each suspended water supply assembly 4. The water in the water supply pipes 11 irrigates the filler in the planting basket 5, and the excess water flows along the water supply pipes 11 into the water tank of the second water supply device 2. The water pump of the second water supply device 2 is used to pump the water in the water tank at the bottom of the rock mass 7 into the water supply pipes 11 of each suspended water supply assembly 4, and the excess water flows back into 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 arranged in the planting basket 5 for monitoring the humidity of the filler. The water level sensor is arranged in the water tanks of the first water supply device 1 and the second water supply device 2. When the humidity is lower than the preset threshold value, the controller starts the water pump in the water tank with a higher water level based on the water level information of the water level sensor. Of course, since the volume of the water tank is fixed, the water level information can be used to calculate the volume of water in the water tank, and the number of planting baskets 5 is known. Therefore, the volume of water required to irrigate all the planting baskets 5 is also known. When it is determined based on the water level information that the water in the water tank is not enough to irrigate all the planting baskets 5, the valve connecting to the municipal pipe network can be opened to supply water into the water tank of the first water supply device 1.

[0038] A plurality of planting baskets 5 are suspended on the suspended water supply assembly 4, and the suspended water supply assembly 4 with the planting baskets 5 suspended is paved 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. It is preferably to plant 5 - 10 planting seedlings 6 per square meter. After the number and density of the planting baskets 5 are determined, the target positions of each planting seedling 6 are determined on the rock surface 8, and based on this, the distribution positions of the suspended water supply assembly 4 and the opening positions of the V-shaped grooves 13 are determined.

[0039] The suspension water supply assembly 4 includes an integral jacket 9, a steel wire rope 10 and a water supply pipe 11 inserted into the integral jacket 9; the water supply pipe 11 is communicated with a branch pipe 32, and the end of the branch pipe 32 extends into the planting basket 5; the integral 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 hoop suspension members 12 hinged to both sides of the V-shaped basket; the V-shaped basket is suspended between two suspension water supply assemblies 4 through the hoop suspension members 12 on both sides thereof; a V-shaped groove 13 is horizontally formed 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 net structure and side plates 14 provided on both sides of the double-layer V-shaped net structure; the double-layer V-shaped net structure includes a V-shaped space formed by maintaining a distance between an outer-layer V-shaped net 15 and an inner-layer V-shaped net 16. The mesh diameters of the outer-layer V-shaped net 15 and the inner-layer V-shaped net 16 are different, and the mesh diameter of the outer-layer V-shaped net 15 is larger than that of the inner-layer V-shaped net 16.

[0042] The filler includes a sponge layer 17, a nutrient soil layer 18, a granular layer 19 and a gravel layer 20; the gravel layer 20 is filled in the V-shaped space; the sponge layer 17, the nutrient soil layer 18 and the granular layer 19 are sequentially filled in the inner space of the inner-layer V-shaped net 16 from bottom to top; the height of the sponge layer 17 is greater than or equal to the depth of the V-shaped groove 13; planting holes passing through the granular layer 19 are provided in the nutrient soil layer 18, and the planting 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 ratio of 5:3:2. The nutrient soil layer 18 can directly adopt the existing conventional nutrient soil. According to the types of the planting seedlings 6, the nutrient soil layer 18 can be adjusted accordingly. The particle size of the gravel layer 20 is between 10-20 mm. The sponge layer 17 is in a triangular prism shape and is horizontally arranged at the bottom of the inner-layer V-shaped net 16.

[0043] As Figure 4 、 Figure 5 shown, the hoop suspension member 12 includes a ball head hinge member 21, an L-shaped boom 22 and a hoop member connected in sequence; the hoop member is connected to the integral jacket 9 by hoop connection; the ball head hinge member 21 is connected to the side plate 14. Under the action of the spherical hinge member, the L-shaped boom 22 can rotate relative to the side plate 14, so as to adjust the relative angle between the hoop member and the side plate 14, thereby realizing the adjustment of the inclination angle of the V-shaped basket.

[0044] The hoop member includes a first hoop piece 23, a second hoop piece 24 and two sets of tie members; the first hoop piece 23 and the second hoop piece 24 are clamped around the upper and lower ends of the integral jacket 9, the first hoop piece 23 is located at the lower end of the integral jacket 9, and the second hoop piece 24 is located at the upper end of the integral jacket 9; the first hoop piece 23 is connected to the L-shaped boom 22; the two sets of tie members respectively tie the two ends of the first hoop piece 23 and the second hoop piece 24, and the two sets of tie members, the first hoop piece 23 and the second hoop piece 24 are closed to form a closed-loop structure surrounding the integral jacket 9.

[0045] Each set of tie members includes an L-shaped limit pin 25 and a tie rope 26. The L-shaped limit pin 25 is arranged at one end of the second hoop piece 24 facing away from the integral jacket 9. One end of the tie rope 26 is connected to the first hoop piece 23, and the other end is connected with a tie ring 27. The tie ring 27 is used for being sleeved on the L-shaped limit pin 25.

[0046] As Figure 7 、 Figure 8 shown, a plurality of metal taps 28 are arranged at intervals along the length direction of the water supply pipe 11. The metal taps 28 are connected with plugs 33 or branch pipes 32; the tie rope 26 winds around the metal tap 28 for at least one turn. The integral jacket 9 includes a fixed sleeve 29 and C-shaped pipes 30 arranged on both sides of the fixed sleeve 29; an opening 31 is arranged on the C-shaped pipe 30; the steel wire rope 10 is inserted into the fixed sleeve 29 and fixedly connected with the fixed sleeve 29; the water supply pipe 11 is inserted into the C-shaped pipe 30, and the metal tap 28 passes out from the opening 31.

[0047] The metal tap 28 is provided with a threaded section, and the plug 33 or the branch pipe 32 is threadedly connected with the metal tap 28. Before installing the planting basket 5, a plug 33 is threadedly connected to each metal tap 28. After the planting basket 5 is placed on the V-shaped groove 13 at the target position, the plug 33 on the metal tap 28 near the planting basket 5 is unscrewed, the branch pipe 32 is connected to the metal tap 28, and the other end of the branch pipe 32 is inserted into the V-shaped space in the planting basket 5 and extends through the inner V-shaped net 16 into the nutrient soil layer 18. The metal taps 28 in the areas where the planting baskets 5 are not installed are still closed by the plugs 33.

[0048] In some embodiments, each set of tie members includes 2 L-shaped limit pins 25 and 2 tie rings 27 connected to the same tie rope 26. The 2 tie rings 27 are sleeved on the 2 L-shaped limit pins 25 in a one-to-one correspondence. Since 2 tie rings 27 are arranged on the same tie rope 26 and are respectively sleeved on 2 L-shaped limit pins 25, the risk that the two tie rings 27 fall off the L-shaped limit pins 25 simultaneously is relatively low.

[0049] When two hoop members on both sides of the V-shaped basket are respectively hooped outside an integral jacket 9, the V-shaped basket is in a suspended state and can slide along the length direction of the integral jacket 9. When encountering the metal tap 28, the sliding is blocked. At this time, it is necessary to manually move the tie ring 27 over the metal tap 28 to continue sliding, so as to avoid the V-shaped basket sliding too far from the target position due to too long a sliding path, or the sliding speed increasing and causing damage due to collision.

[0050] Based on the same inventive concept, the present invention also provides a method for ecological restoration of large dip angle and high steep slope rock masses 7 in southwestern karst areas, which is implemented based on the above ecological restoration system.

The construction worker descends along the suspended water supply assembly 4 to the bottom of the rock mass 7 and releases the buckle of the safety rope. Among them, there can be multiple construction workers, and multiple construction workers carry out the work synchronously, with one construction worker configured on each suspended water supply assembly 4.

[0059] Step 9: Regularly supply water to the planting baskets 5 by using the first water supply device 1 and the second water supply device 2 according to the humidity of the filler.
