Description

Technical Field

[0001] The present invention relates to the technical field of slope biodiversity protection, and in particular to a slope repair structure for a pumped storage power station in arid areas and a use method thereof. Background Art

[0002] Pumped storage, currently the most mature, largest, and most economical energy storage technology, is a crucial tool for building a new power system, promoting green energy transformation, and achieving the strategic goals of "dual carbonization." Pumped storage power stations require upper and lower reservoirs, including specialized construction features such as "two tunnels and one road" (i.e., a water transfer tunnel, a ventilation tunnel, and a connecting road). These systems also create significant disturbance areas, such as large tunnel entrance slopes and the upper and lower slopes of the connecting road.

[0003] The patent announcement number is CN115748757B, an invention patent published on March 7, 2023, which discloses an ecological restoration structure for high and steep rock slopes, including a slope body, a plurality of plant planting holes distributed on the slope surface of the slope body, an arc-shaped groove equal to the number of plant planting holes opened on the slope surface of the slope body, the arc-shaped grooves are arranged one-to-one on the side of the plant planting holes facing the top of the slope body, an arc-shaped water storage cavity is provided in the arc-shaped groove, and a plurality of infiltration tubes are provided at the bottom of the arc-shaped water storage cavity, each of the infiltration tubes extends in the direction close to the plant planting hole. The above patent can improve the storage capacity of rainwater, so as to provide water to plants to facilitate plant growth; but it can only use rainwater as a water source, and the water supply is unstable.

[0004] The patent announcement number is CN112663628B, an invention patent published on April 16, 2021, which discloses an anchor rod-ecological rod combination structural system for ecological restoration of steep rock slopes. This structural system uses special anchor nails to anchor the ecological rod to a flexible non-degradable rubber plate that adapts to the slope surface. On the premise that the anchor rod anchoring has ensured the stability of the slope, the ecological rod combination structure is tied to the steep rock slope surface by connecting the anchor rod and the flexible non-degradable rubber plate with a steel cable, finally forming a stable mechanical structure system, which solves the safety, stability and ecological restoration problems of steep rock slopes, and provides mechanical support for further slope management. However, its anchor rod can only provide the function of reinforcing other devices, and its function is relatively single. Summary of the Invention

[0018] Lay the slope repair structure layer by layer;

[0019] Maintenance slope repair structure and composite connecting pipe.

[0020] Furthermore, the layer-by-layer laying of the slope repair structure includes the following steps:

[0021] Lay the second non-woven fabric on the surface of the third soil layer, and reinforce the second non-woven fabric with embedded steel bars and layering strips;

[0022] The geocell is fixed on the surface of the second non-woven fabric by means of anchor rods or other devices;

[0023] Laying eco-bags inside the geocell;

[0024] Laying a second soil layer outside the geocell;

[0025] Laying a first non-woven fabric on the outside of the second soil layer and fixing the first non-woven fabric with a device such as a rubber strip;

[0026] pouring a concrete grid on the surface of the first non-woven fabric;

[0027] After the concrete grid is cured, the first soil layer is laid inside the concrete grid.

[0028] The present invention has the following beneficial technical effects:

[0029] 1. The present invention uses a composite connecting pipe to connect and fix the slope repair structure with the pressure steel pipe. While reinforcing the entire slope repair structure, the water in the pressure steel pipe can be drawn out to irrigate the plants planted during the slope repair.

[0030] 2. In the present invention, the protective pipe is an outer pipe, the outer periphery of the protective pipe is fixed to each object passing through, and the connecting pipe is an inner pipe. The protective pipe and the connecting pipe are connected by a forced sliding component. When the pressure in the connecting pipe is too high or the electric control door is closed, the connecting pipe can slide outward to prevent excessive pressure from damaging the composite connecting pipe.

[0031] 3. The low-peak electricity consumption is generally at night, and the high-peak electricity consumption is generally during the day. The pumped-storage power station pumps water upward during the low-peak electricity consumption and discharges water downward during the peak electricity consumption. The present invention connects the pressure steel pipe and the connecting pipe through a downward arc joint to prevent water from entering the composite connecting pipe when the pressure steel pipe discharges water during the day, resulting in watering at high temperatures and causing plant death; at the same time, when the pressure steel pipe pumps water upward at night, the arc joint can automatically introduce water for irrigation by the irrigation device.

[0032] 4. The present invention has a humidity sensor fixed on the outside of the protective pipe. The humidity sensor is connected to the electric control door by electrical signals. When the humidity sensor detects that the humidity is high, the electric control door can be controlled to close to prevent the watering device from watering too much and causing the death of plants.

[0033] 5. The telescopic parts fixed between the connecting pipe and the electric control door of the present invention can be extended outward. When the telescopic parts are extended outward, the gaps between the telescopic parts can discharge water to relieve excessive water pressure and prevent damage to the inside of the composite connecting pipe; the spring can retract the telescopic parts or reset the connecting pipe after the pressure returns to normal.

[0034] 6. The irrigation device of the present invention is provided with fan blades. When the water in the connecting pipe is sprayed outward through the nozzle, it will hit the fan blades, driving the fan blades to rotate, thereby dispersing the water and improving the irrigation effect. During the day, there is no water in the pressure steel pipe. Due to the Bernoulli principle, the bottom of the connecting pipe is under negative pressure, so that the connecting pipe can suck air from the outside into the pipe. When the air is sucked in, the fan blades can be automatically driven to rotate, making the fan blades make a sound, which can drive away animals such as moles to dig the slope.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings.

[0047] See also Figures 1-8 The slope repair structure of a pumped-storage power station in arid areas of this embodiment includes a slope repair structure 1 and a composite connecting pipe 2. The slope repair structure 1 includes, from the outside to the inside, a concrete grid 11, a first soil layer 12, a first non-woven fabric 13, a second soil layer 14, a geocell 15, and a second non-woven fabric 17. An eco-bag 16 is provided in the geocell 15. One end of the composite connecting pipe 2 is connected to the pressure steel pipe 3, and the other end of the composite connecting pipe 2 passes through the slope repair structure 1 and extends to the outside of the slope repair structure 1.

[0048] The present invention uses a composite connecting pipe 2 to connect and fix the slope repair structure 1 and the pressure steel pipe 3. While reinforcing the entire slope repair structure 1, water in the pressure steel pipe 3 can be drawn out to irrigate plants planted during slope repair.

[0049] Furthermore, the composite connecting pipe 2 includes a protective pipe 21 and a connecting pipe 22, and the protective pipe 21 is slidingly connected to the connecting pipe 22; the outer periphery of the protective pipe 21 is fixed to the slope repair structure 1 and the third soil layer 4; the bottom of the connecting pipe 22 is connected to the pressure steel pipe 3, and a pouring device 24 is fixed on the top of the connecting pipe 22.

[0050] The protection pipe 21 is an outer pipe, and the outer periphery of the protection pipe 21 is fixed to each object passing through. The connecting pipe 22 is an inner pipe, which serves to connect the irrigation device 24 and the pressure steel pipe 3 to supply water to the irrigation device 24.

[0051] Furthermore, a plurality of forced sliding components are provided between the protective pipe 21 and the connecting pipe 22. The forced sliding components include a sliding groove 211 and a sliding member 221. The sliding groove 211 is fixed to the inner wall of the protective pipe 21, and the sliding member 221 is fixed to the outer wall of the connecting pipe 22. The sliding groove 211 and the sliding member 221 are in contact with each other.

[0052] The protection pipe 21 and the connecting pipe 22 are connected by a forced sliding assembly. When the pressure in the connecting pipe 22 is too high, the connecting pipe 22 can slide outward to prevent the composite connecting pipe 2 from being damaged by the excessive pressure.

[0053] Furthermore, a plurality of rubber balls 23 of different specifications are filled between adjacent forced sliding components.

[0054] The rubber balls 23 can fill the gaps between adjacent forced sliding components to prevent the protective pipe 21 and the communicating pipe 22 from rotating randomly, thereby preventing the forced sliding components from being damaged.

[0055] Furthermore, the bottom of the communicating pipe 22 is connected to the pressure steel pipe 3 via an arc-shaped joint 27 , and the opening of the arc-shaped joint 27 faces downward and is parallel to the pipe wall of the pressure steel pipe 3 .

[0056] In daily life, low electricity consumption is generally at night, and high electricity consumption is generally during the day. The pumped storage power station pumps water upward during low electricity consumption and releases water downward during peak electricity consumption. The present invention connects the pressure steel pipe 3 and the connecting pipe 22 through a downward arc joint 27 to prevent water from entering the composite connecting pipe 2 when the pressure steel pipe 3 releases water during the day, resulting in watering at high temperatures and causing plant death; at the same time, when the pressure steel pipe 3 pumps water upward at night, the arc joint 27 can automatically introduce water for watering by the irrigation device 24.

[0057] Furthermore, an electric control door 25 is fixed between the communication pipe 22 and the irrigation device 24 ; a humidity sensor 29 is fixed to the outer wall of the protection pipe 21 ; and the electric control door 25 and the humidity sensor 29 are connected to each other via electrical signals.

[0058] A humidity sensor 29 is used to detect the ambient humidity around the watering device 24. When the humidity reaches or exceeds a set value, the humidity sensor 29 controls the electric control door 25 to close to prevent the plant from dying due to excessive watering.

[0059] Furthermore, telescopic members 26 are fixed at even intervals between the communicating pipe 22 and the electric control door 25 , and a spring 28 is provided on the outside of the telescopic member 26 . One end of the spring 28 is fixed to the electric control door 25 , and the other end of the spring 28 is fixed to the protective pipe 21 .

[0060] The telescopic part 26 fixed between the connecting pipe 22 and the electric control door 25 can extend outward. When the telescopic part 26 extends outward, the gap between the telescopic parts 26 can discharge water to relieve excessive water pressure and prevent damage to the inside of the composite connecting pipe 2; the spring 28 can retract the telescopic part 26 or reset the connecting pipe 22 after the pressure returns to normal.

[0061] Furthermore, the watering device 24 includes an outer shell 241, a nozzle 243 and a fan blade 245. A cavity is opened inside the bottom surface of the outer shell 241, and the bottom of the outer shell 241 is connected to the connecting pipe 22 through a through hole 242; multiple nozzles 243 are fixed to the bottom surface of the outer shell 241 in a spiral state and evenly spaced, with the top of the nozzle 243 facing the fan blade 245, and the interior of the nozzle 243 is connected to the cavity inside the bottom surface of the outer shell 241; the center of the fan blade 245 is rotatably connected to the top of the support column 244, and the bottom of the support column 244 is fixed to the bottom surface of the inner cavity of the outer shell 241.

[0062] Fan blades 245 are provided in the irrigation device 24. When the water in the connecting pipe 22 is sprayed outward through the nozzle 243, it will hit the fan blades 245, driving the fan blades 245 to rotate, thereby dispersing the water and improving the irrigation effect; during the day, there is no water in the pressure steel pipe 3. Due to the Bernoulli principle, there is a negative pressure at the bottom of the connecting pipe 22, so that the connecting pipe 22 can suck air from the outside into the pipe. When the air is sucked in, the fan blades 245 can be automatically driven to rotate, making the fan blades 245 make a sound, which can drive away animals such as moles to dig the slope.

[0063] As the nozzles 243 are arranged from the center to the sides, the angle between the nozzles 243 and the bottom surface of the housing 241 gradually decreases, so that the nozzles 243 can more appropriately rotate the fan blades 245, and the water spray drives the fan blades 245 to rotate.

[0064] The method for using the slope repair structure for a pumped-storage power station in an arid area according to this embodiment includes the following steps:

[0065] Surface treatment of the slopes of pumped storage power stations;

[0066] Drive the composite connecting pipe 2 into place to connect the composite connecting pipe 2 with the pressure steel pipe 3;

[0067] Lay the slope repair structure layer by layer 1;

[0068] Lay a second non-woven fabric 17 on the surface of the third soil layer 4 and reinforce the second non-woven fabric 17 with embedded steel bars and battens;

[0069] The geocell 15 is fixed on the surface of the second non-woven fabric 17 by means of anchor rods or other devices;

[0070] Laying eco-bags 16 in the geocell 15;

[0071] Laying a second soil layer 14 outside the geocell 15;

[0072] Lay the first non-woven fabric 13 outside the second soil layer 14 and fix the first non-woven fabric 13 with a device such as a rubber strip;

[0073] Casting a concrete grid 11 on the surface of the first non-woven fabric 13;

[0074] After the concrete grid 11 is cured, the first soil layer 12 is laid inside the concrete grid 11;

[0075] Maintain slope repair structure 1 and composite connecting pipe 2.

[0076] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
