DETAILED DESCRIPTION

[0027] The technical solutions of the present application will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0028] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 6 The prefabricated slope protection structure for high-standard farmland construction provided by the embodiments of the present application includes a hexagonal prism 1, the outer wall of the hexagonal prism 1 is provided with a plurality of T-shaped sliding grooves 4, the outer wall of the T-shaped sliding groove 4 is symmetrically provided with a clamping groove, the T-shaped sliding groove 4 of the hexagonal prism 1 is slidably connected with a fixed plate one 13, the inside of the fixed plate one 13 is symmetrically provided with a sliding groove two, the sliding groove two of the fixed plate one 13 is provided with a spring three, one end of the spring three is provided with a clamping block one 12, the side wall of the fixed plate one 13 is provided with a hinged seat one 18, the hinged seat one 18 includes a pair of hinged blocks one, one end of the hinged block one is rotatably connected with a hinged block two through a rotating shaft two, one end of the hinged block two is provided with an adjusting mechanism, one end of the adjusting mechanism is provided with a hinged seat two 20, the hinged seat two 20 includes a hinged block three, the hinged block three is rotatably connected with a hinged block four through a rotating shaft three, one end of the hinged block four is provided with a fixed plate two 21, the inside of the fixed plate two 21 is connected with a spring two 25 through symmetrically arranged sliding grooves three, one end of the spring two 25 is provided with a clamping block two 22.

[0029] Specifically, the hexagonal prism 1 is used as a slope protection foundation bearing unit, and the T-shaped sliding groove 4 on the outer wall of the hexagonal prism 1 is a key structure for connecting the first fixed plate 13 and the second fixed plate 21. When assembling, the operator inserts the first fixed plate 13 and the second fixed plate 21 along the track direction of the T-shaped sliding groove 4. During this process, the clamping block 12 and the clamping block 22 are compressed by the spring 3 and the spring 2 respectively due to the extrusion of the inner wall of the T-shaped sliding groove 4, and are retracted into the sliding groove space inside the first fixed plate 13 and the second fixed plate 21.

[0030] When the fixed plate slides to the preset clamping groove position of the outer wall of the T-shaped sliding groove 4, the elastic potential energy of the spring 3 and the spring 2 is released, pushing the clamping block 12 and the clamping block 22 to pop out and accurately clamp into the clamping groove structure, thereby realizing the rigid clamping and fixing between the fixed plate and the hexagonal prism 1 at the mechanical structure level, and providing a basic connection force for subsequent slope structure splicing.

[0031] The hinge seat 18 and the hinge seat 20 are connected through the adjusting mechanism, and the hinge block 1 and the hinge block 2, and the hinge block 3 and the hinge block 4 can rotate around the rotating shaft 2 and the rotating shaft 3 respectively, so that the adjusting mechanism can adapt to different angles of the slope and changes in the distance between adjacent hexagonal prisms 1, change the overall length of the adjusting mechanism, and then adjust the relative position and connection tightness of adjacent hexagonal prisms 1, so that the slope protection structure adapts to the slope terrain and forms a stable splicing.

[0032] Through the sliding clamping design of the T-shaped sliding groove 4 on the outer wall of the hexagonal prism 1 and the first fixed plate 13 and the second fixed plate 21, the spring 3 and the clamping block 12, and the spring 2 and the clamping block 22 are matched to realize rapid mechanical connection, and the rotating and length adjusting functions of the hinge seat and the adjusting mechanism can adapt to the precise splicing of different slope farmland slopes, improve the structure adaptability and connection stability, and solve the poor adaptability problem of traditional prefabricated slope protection in complex farmland slope terrain.

[0033] Please refer to the accompanying drawings Figure 3 - the accompanying drawings Figure 6 The adjusting mechanism includes an adjusting sleeve 19, one end of the inside of the adjusting sleeve 19 is threadedly connected with a threaded rod 23, the other end of the inside of the adjusting sleeve 19 is threadedly connected with a threaded rod 24, one end of the threaded rod 23 is fixedly arranged at one end of the hinge block 2, and one end of the threaded rod 24 is fixedly arranged at one end of the hinge block 3.

[0034] Specifically, the inner walls of the adjusting sleeve 19 are respectively machined with opposite internal threads, and the outer walls of the threaded rod 23 and the threaded rod 24 are respectively machined with external threads matched with the internal threads of the adjusting sleeve 19. One end of the threaded rod 23 is fixedly arranged at the end of the hinge block 2, and one end of the threaded rod 24 is also fixedly arranged at the end of the hinge block 3, so that the adjusting mechanism forms a linkage structure.

[0035] When the operator rotates the adjusting sleeve 19 clockwise, due to the transmission characteristics of the left-handed thread and the right-handed thread, the threaded rod one 23 will move axially to the left end of the adjusting sleeve 19, and the threaded rod two 24 will move axially to the right end of the adjusting sleeve 19, resulting in the lengthening of the overall length of the adjusting mechanism; conversely, when the adjusting sleeve 19 is rotated counterclockwise, the threaded rod one 23 and the threaded rod two 24 will move towards the inside of the adjusting sleeve 19, causing the overall length of the adjusting mechanism to shorten. This bidirectional threaded transmission design can ensure that the threaded rod one 23 and the threaded rod two 24 produce reverse displacement synchronously during the rotation of the adjusting sleeve 19, avoiding the problem of unbalanced axial force that may occur with single-thread transmission.

[0036] The length change of the adjusting mechanism is transmitted to the hinged block two and the hinged block three through the threaded rod one 23 and the threaded rod two 24, and then drives the relative position change of the hinged seat one 18 and the hinged seat two 20. Since the hinged block one is rotationally connected to the hinged block two through the second rotating shaft, and the hinged block three is rotationally connected to the hinged block four through the third rotating shaft, the adjusting mechanism can allow the hinged seat one 18 and the hinged seat two 20 to rotate within a certain angle range while changing the length, thereby realizing the dual adjustment of the adjacent hexagonal prism 1 in horizontal spacing and vertical angle.

[0037] Through the reverse threaded cooperation of the adjusting sleeve 19 and the threaded rod, the length adjustment and angle adaptation can be achieved, so that the adjacent hexagonal prism 1 can be tightly spliced under different slope gradients, improving the overall stability and terrain adaptability of the slope protection structure. The mechanism has high transmission efficiency and large adjustment range, and the components are made of corrosion-resistant materials and surface treatment, enhancing the long-term reliability. The problems of splicing difficulty, stress concentration and structure cracking caused by spacing and angle deviation in irregular slope terrain of traditional prefabricated slope protection are solved, and the construction period is shortened.

[0038] Please refer to the attached Figure 1 -attached Figure 4 The outer wall of the clamping block two 22 and the clamping block one 12 is slidingly connected inside the sliding groove two of the fixed plate one 13 and the sliding groove three of the fixed plate two 21, and the outer wall of the clamping block two 22 and the clamping block one 12 is clamped with the clamping groove of the T-shaped sliding groove 4.

[0039] Specifically, the sliding connection mechanism of the card block one 12 and the card block two 22 is based on spring energy storage and mechanical clamping principle. The outer wall of the card block one 12 and the outer wall of the card block two 22 are matched with the inner wall of the sliding groove two of the fixed plate one 13 and the inner wall of the sliding groove three of the fixed plate two 21 respectively, forming a linear sliding pair. The spring three and the spring two 25 are respectively arranged in the sliding groove two and the sliding groove three, and one end of each spring is in contact with one side of the card block one 12 and the card block two 22. When the fixed plate one 13 and the fixed plate two 21 slide into the T-shaped sliding groove 4 of the hexagonal prism 1, the inner wall of the T-shaped sliding groove 4 exerts a radial extrusion force on the inclined surface of the card block one 12 and the card block two 22, forcing the card block to overcome the spring force and shrink inward along the sliding groove two and the sliding groove three. The spring is compressed and stores elastic potential energy. When the card block slides to the clamping groove position of the outer wall of the T-shaped sliding groove 4, the spring potential energy is released, pushing the card block one 12 and the card block two 22 into the corresponding clamping grooves respectively, forming a mechanical self-locking structure.

[0040] The cross section of the card block one 12 and the card block two 22 is usually designed as a triangle, and the shape of the clamping groove matches the card block, ensuring that the clamping can withstand the pulling force perpendicular to the direction of the T-shaped sliding groove 4.

[0041] Through the cooperation of the card block one 12, the card block two 22, the fixed plate sliding groove and the spring, automatic clamping connection with the T-shaped sliding groove 4 of the hexagonal prism 1 is realized, the component splicing can be quickly completed, the spring pre-tightening force ensures the tight connection, adapts to the slight undulation of the slope, improves the overall rigidity of the slope protection structure and the construction efficiency. The problem of low construction efficiency and poor precision caused by traditional bolt fastening or welding in precast slope splicing is solved.

[0042] Please refer to the attached Figure 1 -attached Figure 4 The middle part of the hexagonal prism 1 is provided with a cavity 7, the bottom end of the outer wall of the hexagonal prism 1 is provided with a flow guide groove 5, one side of the flow guide groove 5 of the hexagonal prism 1 is provided with a water-retaining cotton 6, and one side of the water-retaining cotton 6 is provided with a plurality of drainage holes 8.

[0043] Specifically, the cavity 7, the flow guide groove 5, the water-retaining cotton 6 and the drainage hole 8 of the hexagonal prism 1 constitute an ecological-drainage collaborative system. The cavity 7 penetrates through the middle part of the hexagonal prism 1, and is filled with a mixture of expanded shale and soil stabilizer inside. The material has a porous structure and has mechanical strength and water permeability. When it rains, the water flow on the slope surface is directed to the flow guide groove 5 along the outer wall of the hexagonal prism 1. The water-retaining cotton 6 is laid inside the flow guide groove 5, and uses the capillary action of the fiber pores to adsorb the water in the water flow. When the water flow exceeds the saturated adsorption capacity of the water-retaining cotton 6, the excess water is discharged from the slope through the drainage holes 8.

[0044] The filling material of the cavity 7 forms a moisture transmission channel with the water-retaining cotton 6: the water adsorbed by the water-retaining cotton 6 can slowly penetrate into the filling material of the cavity 7 through capillary action to provide a continuous water source for the root system of the vegetation. At the same time, the porous structure of the filling material allows air to circulate, preventing the root system from being oxygen-deficient. The position of the drainage hole 8 is 50-100mm higher than the bottom surface of the hexagonal prism 1, preventing the hole channel from being blocked by soil. A one-way water-permeable filter screen is arranged inside the hole channel to block the entry of silt while ensuring smooth water flow.

[0045] By filling the mixture of expanded shale and soil stabilizer in the middle cavity 7 of the hexagonal prism 1, combined with the outer wall flow guide groove 5, water-retaining cotton 6 and drainage hole 8, the rainwater utilization rate can be improved. The water-retaining cotton 6 adsorbs and stores water equivalent to 10 times its own weight and releases it slowly. The drainage hole 8 does not accumulate water under a rainfall intensity of 50mm / h, and the lightweight material reduces the weight of the hexagonal prism 1. The problem of traditional slope protection function fragmentation, poor drainage and difficulty in vegetation growth is solved.

[0046] Please refer to the attached Figure 1 -attached Figure 4 , attached Figure 7 -attached Figure 8 , the top end of the hexagonal prism 1 is symmetrically provided with a pressing rod 3, the top end of the pressing rod 3 is provided with a pressing plate 2, the outer wall of the pressing rod 3 is provided with a fixed column 11 penetrating through the hexagonal prism 1, the top end of the fixed column 11 is arranged at the bottom end of the hexagonal prism 1, the bottom end of the fixed column 11 is provided with a tapered head 9, the inside of the fixed column 11 is provided with a cavity two, the outer wall of the fixed column 11 is symmetrically provided with a containing cavity, the containing cavity of the fixed column 11 is rotatably connected with a rotating shaft one 14, the outer wall of the rotating shaft one 14 is provided with an anti-dropping rod 10, one end of the anti-dropping rod 10 is provided with a pressing block 15, the bottom end of the pressing rod 3 is provided with a top block 16, the outer wall of the top block 16 is slidably connected in the inside of the fixed column 11, the bottom end of the top block 16 is provided with a spring one 17, and the bottom end of the spring one 17 is arranged on the upper surface of the tapered head 9.

[0047] Specifically, the pressing plate 2 at the top end of the hexagonal prism 1 and the pressing rod 3 form a force applying assembly, and the fixed column 11 is penetrated and the anti-dropping rod 10 is contracted and expanded for anchoring through mechanical transmission. When the operator presses the pressing plate 2 downward, the pressing rod 3 slides axially along the penetrating hole of the hexagonal prism 1, the bottom end thereof contacts the top block 16 in the inside of the fixed column 11 and applies pressure. The top block 16 is connected with the spring one 17, and after being pressed, the spring one 17 is compressed, so that the spring accumulates elastic potential energy, and at the same time, the fixed column 11 is pushed downward to move, so that the tapered head 9 cuts into the soil.

[0048] The anti-extraction rod 10 of the outer wall of the fixed column 11 is rotationally connected to the accommodating cavity through the rotating shaft I 14, and the extrusion block 15 at the end of the anti-extraction rod 10 is located on the path of the pressing rod 3. When the fixed column 11 penetrates downward, the extrusion block 15 is pressed by the pressing rod 3, so that the anti-extraction rod 10 rotates and shrinks into the accommodating cavity around the rotating shaft I 14. At this time, the anti-extraction rod 10 is flush with the outer wall of the fixed column 11, and the penetration resistance is reduced. When the tapered head 9 and the fixed column 11 penetrate into the soil to the designed depth, the operator releases the pressing plate 2, the spring I 17 releases the elastic potential energy, pushes the top block 16 to move upward, and drives the fixed column 11 to reset upward. At this time, the extrusion block 15 is released from the constraint of the soil, the anti-extraction rod 10 expands outward around the rotating shaft I 14 under the spring reset force and the reaction force of the soil, and the extrusion block 15 is embedded in the surrounding soil to form a mechanical interlocking to prevent the fixed column 11 from being pulled out.

[0049] Through the mechanical transmission of the pressing plate 2 and the pressing rod 3, the fixed column 11 penetrates into the soil, the anti-extraction rod 10 expands and embeds into the soil when the spring resets, and the spring buffer reduces the penetration resistance during pressing. Artificial operation is not necessary, and mechanical assistance is not necessary. After the anti-extraction rod 10 expands, the contact area with the soil increases, the connection stiffness of the hexagonal column 1 and the soil is improved, and the slope settlement deformation is effectively inhibited. The problems of low efficiency and poor adaptability to settlement in the traditional slope protection anchoring construction are solved.

[0051] Specifically, the farmland slope terrain and geology are precisely surveyed and cleaned by professional equipment, and the performance parameters of each component of the prefabricated member are checked to meet the standards; then the positioning and setting-out are performed by using measuring instruments, the fixed column 11 is inserted into the soil body by pressing the pressing plate 2, and the anchoring stability is enhanced by the spring and the anti-dropping rod 10; then the fixed plate is slid into the six-prism 1T-shaped sliding groove 4 and is preliminarily connected by the spring and the clamping groove, the spacing and angle are adjusted by rotating the adjusting sleeve 19; then the specific lightweight aggregate is filled into the six-prism 1 cavity 7 and is vibrated, the water-retaining cotton 6 is laid and the drainage hole 8 is checked for smoothness; then the seed and nutrient liquid mixed slurry is prepared and is uniformly sprayed, and the maintenance management is performed in stages; finally, the slope protection structure, vegetation and drainage are inspected every month according to the standard, and the problems found are treated according to the corresponding method.
