[0002] A pumped storage power station is a facility that plays a key role in the operation of the power system. It uses the electric energy during the low load period of the power load to pump water to the upper reservoir for storage, and then releases water to the lower reservoir for power generation during the peak period of the power load. Such a power station can not only convert the surplus electric energy during the low grid load into high-value electric energy during the peak period of the grid, but also play multiple roles such as frequency modulation, phase modulation, stabilizing the frequency and voltage in the power system, which is of great significance for improving the stability and efficiency of the power system; currently, reinforcement plates are used to reinforce the dam slopes of pumped storage power stations to prevent the dam slopes from being prone to landslides. Many reinforcement plates are directly installed by inserting soil nails into the soil when installed. However, after using for a certain period of time, the inserted soil nails are prone to slide out and become unstable. Content of the Utility Model

Anti-slip grooves are formed on the alignment heads, and alignment grooves matching the shapes of the alignment heads are respectively formed on the other two ends of the slope protection plate; an earth insertion rod is inserted into the slope protection plate. A pointed head is provided at the front end of the earth insertion rod. Threads are formed at the rear end of the earth insertion rod and it is connected to the slope protection plate through a fixing nut. The earth insertion rod is of a hollow tube structure, and a number of movable holes are evenly formed on the earth insertion rod. The movable holes are distributed in groups, and each group of movable holes is evenly distributed around the circumference of the earth insertion rod. A number of elastic reinforcement structures and insertion rods for fixing are provided inside the earth insertion rod.
[0005] Preferably, the elastic reinforcement structure includes several thorn nails, each thorn nail is slidably installed in the movable hole, the tails of the several thorn nails are all arc-shaped surfaces, and the arc-shaped surfaces are arranged towards the slope protection plate, and an elastic ring band is movably penetrated through the tails of the several thorn nails.

[0007] Preferably, a sealing plug is movably provided at the tail of the earth insertion rod.
[0008] Preferably, a backing plate is provided between the fixing nut and the slope protection plate.
[0009] After adopting the above structure, the beneficial effects of the utility model are:
[0010] 1. The device is provided with an elastic reinforcement structure. By inserting the insertion rod, the spiked nails in the soil-inserting rod are pushed out, so as to penetrate into the soil.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Refer to Figures 1-4As shown in the figure, it includes a slope protection plate 1. Alignment heads 2 are respectively connected to the opposite ends of the slope protection plate 1. Anti-slip grooves 3 are formed in the alignment heads 2. Alignment grooves 4 that match the shape of the alignment heads 2 are respectively formed in the other two ends of the slope protection plate 1; an earth-inserting rod 5 is inserted into the slope protection plate 1. A pointed head 6 is provided at the front end of the earth-inserting rod 5. Threads are formed at the rear end of the earth-inserting rod 5 and it is connected to the slope protection plate 1 through a fixing nut 8. The earth-inserting rod 5 is of a hollow tube structure. A number of movable holes 7 are evenly formed in the earth-inserting rod 5. The movable holes 7 are distributed in groups, and each group of movable holes 7 is evenly distributed along the circumference of the earth-inserting rod 5. A number of elastic reinforcement structures and an inserting rod 11 for fixation are provided inside the earth-inserting rod 5.
[0022] The alignment heads 2 and the alignment grooves 4 are provided so that when multiple slope protection plates 1 are arranged, they can be limited and connected to each other, thereby enhancing the integrity of slope reinforcement, reducing local compression, and preventing local sliding deformation.
[0023] See Figures 1-5 As shown in the figure, the elastic reinforcement structure includes a number of spiked nails 12. Each spiked nail 12 is slidably installed in the movable hole 7. The tails of the number of spiked nails 12 are all arc-shaped surfaces 13, and the arc-shaped surfaces 13 face the slope protection plate 1. An elastic ring band 14 is movably penetrated through the tails of the number of spiked nails 12;
[0024] The outer diameter of the inserting rod 11 matches the inner diameter of the earth-inserting rod 5, and the front end of the inserting rod 11 is a pointed tip.
[0025] As an optimized solution of the present utility model, spiked nails 12 that can slide in the movable holes 7 are provided, and the elastic ring band 14 is used to pull the spiked nails 12 inward, so that the spiked nails 12 can be kept inside the earth-inserting rod 5 when not installed. When the inserting rod 11 is inserted, the pointed tip of the inserting rod 11 pushes forward, and the spiked nails 12 are pushed outwards through the arc-shaped surfaces 13 and penetrate into the soil, thereby performing secondary reinforcement on the earth-inserting rod 5, and at the same time the elastic ring band 14 is stretched.

[0028] As an optimized solution of the present utility model, the sealing plug 10 is provided to seal the inside of the earth-inserting rod 5 and reduce the entry of external moisture. The setting of the backing plate 9 can reduce the local pressure at the fixing nut 8 on the slope protection plate 1 and prevent stress concentration from damaging the slope protection plate 1.
[0029] The usage process of the present utility model:
[0030] First, level and process the slope surface. Then, set the appropriate size of the slope protection plate 1 and the insertion positions of the soil insertion rods 5 according to requirements. Next, nail the soil insertion rods 5 into the dam slope in sequence. Drive the insertion rods 11 into the soil insertion rods 5, and the insertion rods 11 push out the thorn nails 12 in the soil insertion rods 5 in sequence, causing them to penetrate into the soil, thereby fixing the soil insertion rods 5 for the second time and enhancing stability. After that, install the sealing plugs 10 on each soil insertion rod 5;
[0031] After the installation of the soil insertion rods 5 is completed, the slope protection plate 1 can be installed. When installing the first slope protection plate 1, after tightening the fixing nuts 8, rotate the second slope protection plate 1 by 90° and then install it, so that the alignment head 2 is inserted into the alignment groove 4 of the first slope protection plate 1. Then, install the slope protection plates 1 of the entire dam slope in this way and fix them to complete the installation.
