Description

Technical Field

[0001] The present invention relates to the technical field of river slope protection, and particularly to a slope protection device for river regulation and nursing and a construction method thereof. Background Art

[0002] Currently, when regulating and nursing river slopes, the generally adopted relatively efficient three-dimensional net slope protection method is mainly as follows: First, cover the three-dimensional net on the slope surface and fix the three-dimensional net on the slope with U-shaped nails. Then, spray the mud with grass seeds on the three-dimensional net. The three-dimensional net slope protection utilizes the combination of active plants and geosynthetics. Through the mutual entanglement and interweaving of vegetation, net pads, and soil, a firm composite mechanical interlocking system is formed, thereby effectively preventing the slippage of the surface soil layer and improving the stability of the slope.

[0003] Currently, when adopting the three-dimensional net slope protection, generally, construction workers cover the three-dimensional net on the slope surface, and then the workers drive multiple U-shaped nails into the soil one by one to fix the three-dimensional net. When installing the three-dimensional net, the workers need to run back and forth on the slope, which poses a safety hazard of falling. In addition, there are protruding stones and soil blocks on the slope surface. In order to prevent these stones and soil blocks from lifting the three-dimensional net, the workers need to manually clean them when covering the three-dimensional net, resulting in a cumbersome and inconvenient laying process and increasing the labor intensity of the workers.

[0004] On the other hand, a reservoir slope protection device disclosed in the Chinese invention patent application publication specification CN117385816B can effectively intercept solid impurities such as falling stones and mud from entering the reservoir and improve the service life of the reservoir. However, the above scheme is difficult to improve the laying quality of the three-dimensional net. Currently, when laying the three-dimensional net, generally, the rolled three-dimensional net is first covered on the slope surface as a whole, and then fixed with U-shaped nails. However, when the three-dimensional net is first covered on the slope surface as a whole, the three-dimensional net will tilt and slide along the slope due to its own gravity, resulting in a poor covering position of the three-dimensional net. In addition, due to the existence of some arc-shaped pits on the slope surface during excavation, when directly laying the three-dimensional net, the three-dimensional net tilts and slides along the slope under the action of gravity, causing the three-dimensional net to be overly flattened, resulting in gaps between the three-dimensional net and the arc-shaped pits. These gaps are not conducive to the germination and rooting of seeds after spraying, thus affecting the protection work of the river slope. Therefore, we propose a slope protection device for river regulation and nursing and a construction method thereof to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and propose a slope protection device for river regulation and nursing. This device can lay a three-dimensional net in a way that fits the slope surface, effectively avoiding gaps between the slope surface and the three-dimensional net. While laying the three-dimensional net, U-shaped nails are fixed to effectively prevent the three-dimensional net from tilting and sliding due to gravity, resulting in poor coverage of the slope surface. In addition, this device can use a striking method to make the stones and soil blocks remaining on the slope surface move away from the laying area.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A slope protection device for river regulation and nursing, including a main frame. Pressing mechanisms are arranged on both sides of the main frame. The pressing mechanism includes a support block, a fixing plate, and a rotating cylinder. A traveling wheel is fixed on the outer surface of the rotating cylinder. A clearance clearing mechanism is arranged outside the rotating cylinder. The clearance clearing mechanism includes a sliding plate and a pressure-receiving column. A ring plate is fixed on the outer surface of the rotating cylinder. A plurality of convex blocks arranged in a circumferential array are fixed on the inner wall of the ring plate. The convex blocks are adapted to the pressure-receiving column. The pressure-receiving column is fixed to the sliding plate. A clearance clearing plate is fixed to the bottom end of the sliding plate.

[0007] A conveying mechanism is arranged outside the support block. The conveying mechanism includes a first notched plate, a notched ring, and a second notched plate. The first notched plate, the notched ring, and the second notched plate are all fixed to the support block. A rotating ring is rotatably connected to the inner wall of the notched ring. The rotating ring is fixed to the rotating cylinder. Sliding groove groups are formed on the mutually approaching surfaces of the first notched plate and the second notched plate. The sliding groove group includes an inner arc groove, a retraction groove, and two outer arc grooves. Both of the two outer arc grooves are communicated with the retraction groove, and both of the two outer arc grooves are communicated with the inner arc groove. The conveying mechanism further includes two groups of sliding columns. The number of each group of sliding columns is eighteen and they are arranged in a circumferential array. Each sliding column is slidably connected to the rotating ring. A pin is fixed on the outer surface of each sliding column. Each pin is slidably connected to the rotating ring. The two groups of sliding columns are respectively slidably connected to the two sliding groove groups.

[0008] A retention groove for the passage of U-shaped nails is formed on the inner wall of the rotating ring. A limiting ring for limiting the U-shaped nails is fixed to the side of the first notched plate close to the notched ring. A knocking mechanism is arranged on the side of the first notched plate away from the notched ring. The knocking mechanism includes an impact column, and the impact column is slidably and internally connected to the limiting ring.

[0009] Further, a driving carrier is arranged outside the main frame, a hydraulic telescopic frame is installed on the outer surface of the driving carrier, the telescopic end of the hydraulic telescopic frame is fixed to the main frame, a winding machine is arranged between the two pressing mechanisms, the two fixing plates are installed with the winding machine, a driven roller is arranged below the winding machine, the two supporting blocks are installed with the driven roller, an arc-shaped baffle and a cover plate are arranged between the two conveying mechanisms, the two first notch plates are both fixed to the arc-shaped baffle, the two second notch plates are both fixed to the cover plate, and a linear cutting machine is installed on the outer surface of the cover plate.

[0010] By adopting the above technical solution, after the three-dimensional net is laid, the linear cutting machine is controlled to move linearly to cut the three-dimensional net. While the cutting operation is completed, the three-dimensional net above the arc-shaped baffle is still limited by a plurality of nail pins. The main frame is controlled to move obliquely upward and reset by the hydraulic telescopic frame, and the next laying work can be carried out, making the process of laying the three-dimensional net convenient and fast.

[0011] A rod one is fixed on the outer surface of the above-mentioned supporting block, the rod one is slidably connected with the fixing plate, a spring one is sleeved outside the rod one, and both ends of the spring one are fixed to the fixing plate and the supporting block respectively. A ring rail is rotatably connected to the outer surface of the rotating cylinder, and a rod two is fixed above the ring rail, and the rod two is slidably connected with the fixing plate.

[0012] By adopting the above technical solution, the supporting block is subjected to the spring pressure of the spring one, so that both the notch ring and the arc-shaped baffle are kept close to the slope surface. When the device travels to the arc-shaped pit, the notch ring and the arc-shaped baffle can press the three-dimensional net against the slope surface.

[0013] Further, the obstacle clearing mechanism further includes a fixed seat fixed on the ring rail, a pawl is hinged on the outer surface of the fixed seat, a spring three is fixed between the pawl and the fixed seat, a ratchet ring is fixed on the outer surface of the ring plate, the ratchet ring is engaged with the pawl, a slide rail is fixed on the outer surface of the ring rail, a sliding plate is slidably connected with the slide rail, and a spring two is fixed between the sliding plate and the slide rail.

[0014] By adopting the above technical solution, when the multiple bumps in the ring plate strike the pressure column multiple times, the sliding plate will be reset under the spring pressure of the spring two, so that the sliding plate drives the obstacle clearing plate to reciprocate, and the obstacle clearing plate can strike the soil blocks and stone blocks on the slope surface multiple times.

[0015] Further, the conveying mechanism further includes two fixing frames and two stoppers. The two fixing frames are respectively fixed to the first notch plate and the second notch plate. A set of fixing columns are fixed to the inner walls of the two fixing frames, with two fixing columns in each set. The two sets of fixing columns are respectively slidably connected to the two stoppers, and the two stoppers are both slidably connected to the notch ring. A set of eight springs are fixed to the outer surfaces of the two stoppers, with two springs in each set. The two sets of eight springs are respectively fixed to the two fixing frames.

[0016] By adopting the above technical solution, when the two stoppers are attached to each other under the elastic force of the eight springs, the two stoppers will block the notch of the notch ring to prevent the U-shaped nails in the retention groove from falling off.

[0017] Further, a feeding mechanism is arranged outside the support block. The feeding mechanism includes a storage box fixed to the support block. A push plate is arranged inside the storage box, and the storage box is slidably connected to the push plate. A rod three is fixed to the outer surface of the support block, and the rod three is slidably connected to the push plate. A spring four is sleeved on the outer surface of the rod three, and the two ends of the spring four are respectively fixed to the support block and the push plate. An electric push rod A is fixed to the outer surface of the storage box, and a push plate is fixed to the telescopic end of the electric push rod A. A through pipe is fixedly communicated with the outer surface of the storage box, and the through pipe is fixedly communicated with the notch ring.

[0018] By adopting the above technical solution, a plurality of U-shaped nails are filled in the storage box. The push plate presses the U-shaped nails under the elastic force of the spring four. When the retention groove moves to the position of the through pipe, the electric push rod A is controlled to drive the push plate to press the U-shaped nails, and the U-shaped nails are pushed into the retention groove through the through pipe.

[0019] Further, the knocking mechanism includes a motor fixed to the first notch plate. The output end of the motor is fixed with a reciprocating threaded rod. The bottom end of the reciprocating threaded rod is rotatably connected to a support frame, and the support frame is fixed to the outer surface of the first notch plate. A housing one is threadedly connected to the outer surface of the reciprocating threaded rod. A wedge block one is slidably connected to the inner wall of the housing one. A spring five is fixed between the wedge block one and the inner wall of the housing one. A wedge block two is fixed to the upper surface of the wedge block one. A rod four is fixed to the outer surface of the first notch plate, and the rod four is slidably connected to the housing one. A top column is arranged above the wedge block two, and the top column is fixed to the first notch plate.

[0020] A rod five is fixed to the outer surface of the notch plate one. An activity plate is slidably connected to the outer surface of the rod five. The activity plate is fixed to the impact column. A plate is fixed to the top end of the rod five. A spring seven is sleeved on the outer surface of the rod five. Two ends of the spring seven are respectively fixed to the plate and the activity plate. A counterweight is fixed to one side of the activity plate. A pressure receiving plate is fixed to the other side of the activity plate. A limiting block is fixed to the upper surface of the pressure receiving plate. An electric push rod B is fixed to the outer surface of the notch plate one. A telescopic end of the electric push rod B is fixed to a housing two. A wedge block three is slidably connected to the inner wall of the housing two. A spring six is fixed between the wedge block three and the inner wall of the housing two.

[0021] By adopting the above technical solution, when the retention groove drives the U-shaped nail to move to the notch of the notch ring, control the motor to drive the reciprocating threaded rod to rotate. The rotation of the reciprocating threaded rod drives the housing one to move up and down reciprocally. When the housing one rises, it will jack up the pressure receiving plate. After the pressure receiving plate continues to rise, the wedge block two will be extruded by the jacking column, so that the wedge block two drives the wedge block one to retract into the housing one. At this time, the pressure receiving plate will move downward under the gravity of the counterweight and the spring pressure of the spring seven, so that the activity plate drives the impact column to impact the U-shaped nail. And when the housing one moves downward, the wedge block one will cross over the pressure receiving plate, so that the wedge block one can jack up the pressure receiving plate again, thus circulating repeatedly, and making the impact column strike the U-shaped nail multiple times to insert it into the slope surface.

[0022] The construction method of the slope protection device for river regulation and nursing is as follows:

[0023] Step 1: Control the driving carrier to move the device to the slope protection area. Control the hydraulic telescopic frame to move the main frame, so that the traveling wheels roll on the slope surface. The rolling of the traveling wheels drives the rotating cylinder to rotate. The rotating cylinder will drive the multiple sliding columns on the rotating ring to rotate. When the sliding columns slide into the outer arc grooves, the sliding columns will push out the nail pins so that the nail pins are inserted into the three-dimensional net. The three-dimensional net is conveyed along the surface of the notch ring. The supporting block moves downward under the spring pressure of the spring one, so that the supporting block presses down the notch ring, and the three-dimensional net on the surface of the notch ring fits the slope surface for laying, and the laying work is completed.

[0024] Step 2: When the rolling of the traveling wheels drives the rotating cylinder to rotate, the rotating cylinder drives the ring plate to rotate. The multiple convex blocks in the ring plate will strike the pressure receiving column multiple times, so that the pressure receiving column drives the obstacle clearing plate to strike the stones and soil blocks remaining on the slope surface through the sliding plate, so that the stones and soil blocks are far away from the laying area, and the obstacle clearing work is completed.

[0025] Step 3: When the rotating ring rotates to drive the retention groove to move to the through pipe, the U-shaped nails are installed in the retention groove through the feeding mechanism. When the retention groove continues to rotate and move to the notch of the notch ring, the motor is started to drive the reciprocating threaded rod to rotate, causing the first housing to move up and down reciprocally. The rod four in the first housing lifts the pressure plate multiple times. After the pressure plate is lifted, due to gravity and the spring pressure of spring seven, the pressure plate drives the impact column on the movable plate to strike the U-shaped nails in the retention groove, causing the U-shaped nails to pass through the three-dimensional net and insert into the slope surface, completing the fixing work.

[0026] Compared with the prior art, the slope protection device for river regulation and nursing and its construction method have the following beneficial effects:

[0027] 1. In the present invention, by setting a pressing mechanism, a conveying mechanism and a knocking mechanism, when the walking wheels roll on the slope surface to drive the rotating ring to rotate, the pin in the rotating ring pops out and inserts into the upper three-dimensional net, causing the three-dimensional net to be conveyed along the surface of the notch ring to the slope surface. At the same time, the support block cooperates to press the notch ring, so that the three-dimensional net on the surface of the notch ring fits the slope surface for laying, effectively avoiding gaps between the slope surface and the three-dimensional net. While laying the three-dimensional net, the impact column knocks the U-shaped nails, and the three-dimensional net is fixed on the slope surface through the U-shaped nails, effectively preventing the three-dimensional net from tilting due to gravity and resulting in poor coverage position on the slope surface.

[0028] 2. In the present invention, through the pressing mechanism and the obstacle clearing mechanism, when the walking wheels roll on the slope surface, it will drive the rotating cylinder to rotate. The multiple convex blocks in the rotating cylinder driving the ring plate to rotate will strike the pressure receiving column multiple times, causing the pressure receiving column to drive the obstacle clearing plate to strike the stones and soil blocks remaining on the slope surface through the sliding plate, making the stones and soil blocks move away from the laying area, effectively preventing the problem that the three-dimensional net is difficult to fit the slope surface because the stones and soil blocks lift the three-dimensional net. In addition, after laying and fixing the three-dimensional net, the three-dimensional net is cut by the linear cutting machine, and then the main frame is reset through the driving carrier for the next laying. Therefore, the device can continuously carry out the laying, fixing and cutting operations of the three-dimensional net, making the river slope protection operation convenient and fast and reducing the labor intensity of the staff.

[0029] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

The support block 401 is subjected to the spring pressure of the spring 404, so that the gap ring 702 and the arc baffle 13 are kept close to the slope surface. When the device reaches the arc pit, the gap ring 702 and the arc baffle 13 can press the three-dimensional net to fit the slope surface.

[0059] Please refer to Figure 8 and Figure 9 The obstacle clearing mechanism 5 also includes a fixed seat 508 fixed on the ring rail 406, a pawl 509 is hinged on the outer surface of the fixed seat 508, a spring three 510 is fixed between the pawl 509 and the fixed seat 508, a ratchet ring 503 is fixed on the outer surface of the ring plate 501, the ratchet ring 503 is meshed with the pawl 509, a slide rail 504 is fixed on the outer surface of the ring rail 406, a sliding plate 505 is slidably connected to the slide rail 504, and a spring two 507 is fixed between the sliding plate 505 and the slide rail 504.

[0061] When the rolling of the slope drives the rotating ring 705 to rotate, multiple sliding columns 707 in the rotating ring 705 slide into the outer arc groove 601, and the outer arc groove 601 will push the sliding column 707 to push out the nail pin 706, and the nail pin 706 will be pushed out and inserted into the three-dimensional net above. Multiple nail pins 706 will move the three-dimensional net, so that the three-dimensional net is transmitted to the slope along the surface of the notch ring 702.

[0062] Please refer to Figure 11 , Figure 13 and Figure 15 When the sliding column 707 in the inner arc groove 602 slides into the outer arc groove 601, the sliding column 707 will drive the nail pin 706 to extend from the rotating ring 705, so that the nail pin 706 pierces the three-dimensional net; when the sliding column 707 in the outer arc groove 601 slides into the retraction groove 603, the nail pin 706 retracts into the rotating ring 705, which is convenient for the linear cutting machine 15 to cut the three-dimensional net, and the sliding column 707 in the retraction groove 603 slides into the outer arc groove 601, and the nail pin 706 extends out and pierces the three-dimensional net; when the sliding column 707 in the outer arc groove 601 slides into the inner arc groove 602, the nail pin 706 retracts into the rotating ring 705 to prevent the nail pin 706 from rotating and scratching the laid three-dimensional net.

[0063] Please refer to Figure 13 and Figure 14, the conveying mechanism 7 further includes two fixed frames 709 and two stoppers 712. The two fixed frames 709 are respectively fixed to the first notch plate 701 and the second notch plate 703. A set of fixing columns 710 are fixed to the inner walls of the two fixed frames 709. The number of fixing columns 710 in each set is two. The two sets of fixing columns 710 are respectively slidably connected to the two stoppers 712. The two stoppers 712 are both slidably connected to the notch ring 702. A set of eight springs 711 are fixed to the outer surfaces of the two stoppers 712. The number of eight springs 711 in each set is two. The two sets of eight springs 711 are respectively fixed to the two fixed frames 709. When the two stoppers 712 are in contact with each other under the elastic force of the eight springs 711, the two stoppers 712 will block the notch of the notch ring 702 to prevent the U-shaped nails in the retention groove 708 from falling. When the U-shaped nails are struck, the U-shaped nails can push open the two stoppers 712.

[0064] Please refer particularly to Figure 10 and Figure 16 , a feeding mechanism 8 is arranged outside the support block 401. The feeding mechanism 8 includes a storage box 801 fixed to the support block 401. A push plate 803 is arranged inside the storage box 801. The storage box 801 is slidably connected to the push plate 803. A third rod 804 is fixed to the outer surface of the support block 401. The third rod 804 is slidably connected to the push plate 803. A fourth spring 805 is sleeved on the outer surface of the third rod 804. The two ends of the fourth spring 805 are respectively fixed to the support block 401 and the push plate 803. An electric push rod A806 is fixed to the outer surface of the storage box 801. A push plate 807 is fixed to the telescopic end of the electric push rod A806. A through pipe 802 is fixedly connected to the outer surface of the storage box 801. The through pipe 802 is fixedly connected to the notch ring 702.

[0065] Fill a plurality of U-shaped nails in the storage box 801. The push plate 803 presses the U-shaped nails under the elastic force of the fourth spring 805. When the retention groove 708 moves to the position of the through pipe 802, control the electric push rod A806 to drive the push plate 807 to press the U-shaped nails, and push the U-shaped nails into the retention groove 708 through the through pipe 802.

[0066] A retention groove 708 for the passage of U-shaped nails is formed in the inner wall of the rotating ring 705. A limiting ring 704 for limiting the U-shaped nails is fixed to the side of the first notch plate 701 close to the notch ring 702. A knocking mechanism 9 is arranged on the side of the first notch plate 701 away from the notch ring 702. The knocking mechanism 9 includes an impact column 909. The impact column 909 is slidably connected to the inside of the limiting ring 704.

[0067] Please refer particularly to Figure 6 and Figure 7, the knocking mechanism 9 includes a motor 901 fixed on the first notch plate 701. A reciprocating threaded rod 902 is fixed to the output end of the motor 901. The bottom end of the reciprocating threaded rod 902 is rotatably connected to a support frame, and the support frame is fixed on the outer surface of the first notch plate 701. A housing 903 is threadedly connected to the outer surface of the reciprocating threaded rod 902. A first wedge block 905 is slidably connected to the inner wall of the housing 903. A fifth spring 907 is fixed between the first wedge block 905 and the inner wall of the housing 903. A second wedge block 906 is fixed to the upper surface of the first wedge block 905. A fourth rod 904 is fixed to the outer surface of the first notch plate 701. The fourth rod 904 is slidably connected to the housing 903. Above the second wedge block 906, there is a top column 914, and the top column 914 is fixed to the first notch plate 701.

[0068] When the retention groove 708 drives the U-shaped nail to move to the notch of the notch ring 702, control the motor 901 to drive the reciprocating threaded rod 902 to rotate. The rotation of the reciprocating threaded rod 902 drives the housing 903 to move up and down reciprocally. When the housing 903 rises, it will lift the pressing plate 911. After the pressing plate 911 continues to rise, the second wedge block 906 will be squeezed by the top column 914, causing the second wedge block 906 to drive the first wedge block 905 to retract into the housing 903. At this time, the pressing plate 911 will move downward under the gravity of the weight 913 and the spring pressure of the seventh spring 919, causing the movable plate 908 to drive the impact column 909 to strike the U-shaped nail. And when the housing 903 moves downward, the first wedge block 905 will pass over the pressing plate 911, enabling the first wedge block 905 to lift the pressing plate 911 again, thus repeating the cycle and causing the impact column 909 to strike the U-shaped nail multiple times to insert it into the slope surface.

[0069] A fifth rod 910 is fixed to the outer surface of the first notch plate 701. A movable plate 908 is slidably connected to the outer surface of the fifth rod 910. The movable plate 908 is fixed to the impact column 909. The top end of the fifth rod 910 is fixed to a plate 920. A seventh spring 919 is sleeved on the outer surface of the fifth rod 910. The two ends of the seventh spring 919 are respectively fixed to the plate 920 and the movable plate 908. A weight 913 is fixed to one side of the movable plate 908. A pressing plate 911 is fixed to the other side of the movable plate 908. A limiting block 912 is fixed to the upper surface of the pressing plate 911. An electric push rod B915 is fixed to the outer surface of the first notch plate 701. The telescopic end of the electric push rod B915 is fixed to a housing 916. A third wedge block 917 is slidably connected to the inner wall of the housing 916. A sixth spring 918 is fixed between the third wedge block 917 and the inner wall of the housing 916.

[0070] After the impact post 909 strikes the U-shaped nail into the slope multiple times, control the electric push rod B915 to drive the spring six 918 to move, so that the wedge block three 917 moves to the position corresponding to the limit block 912. When the pressure receiving plate 911 drives the limit block 912 to rise, the wedge block three 917 will be inserted into the limit block 912 to limit the pressure receiving plate 911, so that the impact post 909 is located in the limit ring 704, preventing the impact post 909 from interfering with the rotating rotating ring 705.

[0071] The construction method of the slope protection device for river regulation and nursing is as follows:

[0072] Step 1: Control the driving carrier 2 to move the device to the slope protection area, control the hydraulic telescopic frame 3 to move the main frame 1, so that the traveling wheels 408 roll on the slope surface. The rolling of the traveling wheels 408 drives the rotating cylinder 407 to rotate. The rotating cylinder 407 will drive the multiple sliding columns 707 on the rotating ring 705 to rotate. When the sliding column 707 slides into the outer arc groove 601, the sliding column 707 will eject the nail pin 706 so that the nail pin 706 is inserted into the three-dimensional net. The three-dimensional net is conveyed along the surface of the notch ring 702. At the same time, the support block 401 moves downward under the spring pressure of the spring one 404, so that the support block 401 presses down the notch ring 702 and the arc-shaped baffle 13, so that the three-dimensional net on the surfaces of the notch ring 702 and the arc-shaped baffle 13 fits the slope surface for laying, completing the laying work and avoiding gaps between the three-dimensional net and the slope surface.

[0073] Step 2: When the traveling wheels 408 roll to drive the rotating cylinder 407 to rotate, the rotating cylinder 407 drives the ring plate 501 to rotate. The multiple convex blocks 502 in the ring plate 501 will strike the pressure receiving column 506 multiple times. After the pressure receiving column 506 is not squeezed by the convex blocks 502, the sliding plate 505 will be reset under the spring pressure of the spring two 507, so that the sliding plate 505 drives the obstacle clearing plate 10 to reciprocate, so that the obstacle clearing plate 10 can strike the soil blocks and stone blocks on the slope surface multiple times, completing the obstacle clearing work, effectively avoiding the three-dimensional net being lifted by the soil blocks and stone blocks and not fitting the slope surface.

[0074] Step 3: When the rotating ring 705 rotates to drive the retention groove 708 to move to the through pipe 802, the U-shaped nails are installed in the retention groove 708 through the feeding mechanism 8. When the retention groove 708 continues to rotate and move to the notch of the notch ring 702, stop the hydraulic telescopic frame 3 so that the main frame 1 no longer moves, and start the motor 901 to drive the reciprocating threaded rod 902 to rotate, so that the housing one 903 moves up and down reciprocally. The rod four 904 in the housing one 903 lifts the pressure receiving plate 911 multiple times. After the pressure receiving plate 911 is lifted, due to gravity and the spring pressure of the seventh spring 919, the pressure receiving plate 911 drives the impact column 909 on the movable plate 908 to strike the U-shaped nails in the retention groove 708, so that the U-shaped nails pass through the three-dimensional net and are inserted into the slope, completing the fixing work, enabling the three-dimensional net laying work and the fixing work to be carried out simultaneously, and effectively preventing the problem that the three-dimensional net tilts due to gravity and the coverage position on the slope is not good.
