Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a slope protection and reinforcement device for water conservancy projects. Background Art

[0002] Slope protection in water conservancy projects is widely used in rivers, dams, reservoirs, drainage channels and urban drainage systems; due to various natural conditions such as heavy rain, drought, earthquake or the influence of water infiltration and flow, the service life of slope protection will be greatly reduced, so a variety of slope reinforcement methods are used, such as concrete reinforcement, anchor rod and anchor cable reinforcement, and vegetation reinforcement; among them, the method of using concrete as the basis and then laying a vegetation layer for reinforcement is widely used, especially in cities, which can not only strengthen the slope protection, but also is beneficial to environmental protection and increase urban greening.

[0003] In addition, many slope protection reinforcement devices are designed at the same time. The existing vegetation layer slope protection design generally only installs a layer of protection net on the surface of the vegetation layer. Although it can play a certain role in preventing soil from falling, when there is frequent intermittent erosion or the water level of the river channel rises and falls frequently, it will still cause a large amount of soil loss due to the inability to drain. For example, the Chinese utility model patent with document number CN215052627U, named as a water conservancy project ecological protection device, lays a vegetation layer on the surface of the slope protection base, and installs a layer of protection net on the surface of the vegetation layer. When using a similar scheme, a large amount of soil and water that the vegetation cannot absorb in time will accumulate in the vegetation layer when it rains or the water rises. The vegetation layer will be soaked for a long time to make it too soft and easy to lose. The soil mixed with rainwater will further pollute the river. Especially in intermittent rainy seasons, soil loss is more serious, and the slope protection structure is seriously damaged. Summary of the invention

[0028] The top of the venturi tube 17 is lower than the surface of the vegetation layer 4; a suspension ball 19 is connected to the middle of the elastic metal mesh 28; the suspension ball 19 can be made of corrosion-resistant plastic, corrosion-resistant foam plastic, foam metal, etc., and the density is generally selected to be close to that of a water seal, so that it is easy to suspend but not easy to move with the water. If the buoyancy is too large, it is easy to move with the water and thus pull the elastic metal mesh 28 vigorously; the suspension ball 19 corresponds to the venturi tube 17 and is located above it.

[0029] A connecting rod 20 is connected to the bottom of the suspension ball 19, and a sealing plug 21 capable of blocking the middle of the venturi tube 17 is connected to the bottom of the connecting rod 20. The cross section of the sealing plug 21 is circular, and the circular diameter is equal to or slightly larger than the middle diameter of the venturi tube 17; a guide rod 22 inserted into the venturi tube 17 is connected to the bottom of the sealing plug 21; when the suspension ball 19 is washed by water and floats up and separates from the venturi tube 17, and the sealing plug 21 separates from the middle of the venturi tube 17, and the venturi tube 17 completely loses its blockage, the guide rod 22 is at least partially still located in the venturi tube 17, and the length of the guide rod 22 is designed accordingly; this scheme is generally not applied to complete The suspending ball 19 is mainly used to pull up the sealing plug 21, and the guide rod 22 prevents the sealing plug 21 from completely separating from the Venturi tube 17 and causing the sealing plug 21 to fall into the wrong position after the water recedes.

[0030] A protection box 23 is fixedly connected to the outside of the venturi tube 17, and the protection box 23 is fully enclosed. A micro motor 24 and a wireless signal receiving module 25 are installed inside the protection box 23. The wireless signal receiving module 25 is electrically connected to the micro motor 24. The wireless signal receiving module 25 receives external signals such as radio signals and converts them into signals that the micro motor 24 can understand, thereby driving the micro motor 24; the output end of the micro motor 24 is connected to the output shaft, and the output shaft passes through the protection box 23 and the venturi tube 17 and then is connected to the first magnet 26. The suspension ball 19 is vertically installed corresponding to the first magnet 26 The second magnet 27; the first magnet 26 and the second magnet 27 are both permanent magnets; when the venturi tube 17 is draining water, the first magnet 26 and the second magnet 27 repel each other, and when the drainage is completed and needs to be dropped, the first magnet 26 and the second magnet 27 attract each other; the conversion from the repulsion of the two magnets to the mutual attraction is achieved by the micro motor 24 driving the first magnet 26 to rotate the magnetic poles; the output shaft passes through the protection box 23 and the venturi tube 17, and a bearing is sleeved on the outside, and a bearing seat is arranged outside the bearing, and the bearing seat is fixedly connected to the venturi tube 17 and the protection box 23, and the bearing and the bearing seat are sealed by an O-ring.

[0031] The vegetation layer 4 is rectangular, and the four corners of the elastic metal mesh 28 are fixed to the four corners of the vegetation layer 4; the edge of the vegetation layer 4 is inserted into a concrete hollow column 7 cast as one with the slope protection foundation 1; a positioning pile 8 is arranged inside the concrete hollow column 7, and a middle hole that runs through the upper and lower parts is arranged in the middle of the positioning pile 8, and a movable column 10 is arranged in the middle hole; a limiting groove 14 is arranged inside and outside the positioning pile 8 around the middle hole, and the limiting groove 14 is connected to the middle hole; a limiting block 15 extending into the limiting groove 14 is arranged on the side of the movable column 10 corresponding to the limiting groove 14, and a spring 16 is arranged between the top of the limiting block 15 and the top of the limiting groove 14; when the movable column 10 rises, the limiting block 15 compresses the spring 16 upward; the top of the movable column 10 is fixedly connected to the fixed rod 13, and the fixed rod 13 is connected to the elastic metal mesh 28; the elastic metal mesh 28 includes at least a main rope 2801, which connects two adjacent fixed rods 13 and is also used to connect the fixed rod 13 with the suspended ball 19.

[0032] An elastic sleeve 9 is attached to the inner wall of the middle hole, and the elastic sleeve 9 is squeezed and arranged between the movable column 10 and the inner wall of the middle hole.

[0033] An installation groove connected to the middle hole and the limit groove 14 is opened upward at the bottom of the positioning pile 8, a sealing plug 11 is inserted into the installation groove, and a sealing ring 12 is squeezed between the sealing plug 11 and the inner wall of the installation groove; the installation groove is opened to facilitate the opening of the middle hole and the limit groove 14, and to facilitate the installation of the spring 16 and the limit block 15; the sealing ring 12 is made of rubber, polyurethane or metal, etc., and has certain pressure resistance, wear resistance and chemical corrosion resistance to prevent cement from entering.

[0034] A receiving groove 5 is provided at the slope protection foundation 1 below the vegetation layer 4, and water filter plates 6 are arranged at intervals along the length direction of the receiving groove 5; the aperture of the water filter plate 6 can only filter water, and most particles after the mixture of soil and water are large and cannot pass through; the receiving groove 5 is used to receive muddy water, bumps, gravel, etc. falling from the slide, and even if it is submerged in water, it can complete the precipitation of part of the gravel and soil; after the water recedes, the muddy water and gravel in the receiving groove 5 solidify and can be taken out for use elsewhere, which can further reduce soil loss.

[0035] The middle part (i.e., the throat) of the venturi tube 17 can be connected to multiple branch tubes, one end of which is connected to the throat entrance end of the venturi tube 17, and the other end passes through the vegetation layer 4 and extends to its surface. The ends of the multiple branch tubes are distributed as evenly as possible on the surface of the vegetation layer 4.

[0036] The construction process of the slope protection and reinforcement device for water conservancy projects is as follows: first, the slope protection foundation 1 is cast, and the receiving groove 5 is cast at the same time. After the casting of the receiving groove 5 is completed, the water filter plates 6 are inserted in sequence along its length at a certain interval; then the size of each vegetation layer 4 is divided; after the division is completed, the position of the concrete hollow column 7 and the drainage pipe 18 is determined; before this, the positioning piles 8 and ancillary facilities are prefabricated in the factory; the prefabricated positioning pile 8 first opens an installation groove at the bottom, then opens a middle hole in the middle of the installation groove, and opens a limit groove 14 around the middle hole at the top of the installation groove; then the spring 16 is installed, and after the installation is completed, the prefabricated movable column 10 and its upper limit block 15 are inserted from the bottom of the positioning pile 8; insert After that, insert the sealing plug 11 into the installation groove with the sealing ring 12 to seal the bottom of the positioning pile 8; then place the positioning pile 8 and the auxiliary structure in the middle of the determined position of the concrete hollow column 7, install the casting template of the concrete hollow column 7 outside it, cast the positioning pile 8 and the concrete hollow column 7 as one, so as to fix the positioning pile 8; reduce the corrosion of the soil and the muddy water in the soil; install the casting template of the drainage pipe 18 at the determined position of the drainage pipe 18, and leave a hole for the Venturi tube 17 to be inserted, and insert the Venturi tube 17 together during casting and then cast it fixed; after casting, lay the vegetation layer 4, lay the concrete slab for casting and blocking, and raise one end of the second slide 3; then install the elastic metal mesh 28.

[0037] When working, the micro motor 24 is controlled by the wireless signal receiving module 25, and the micro motor 24 drives the output shaft, and the output shaft drives the first magnet 26 and the second magnet 27 to repel each other, thereby lifting the Venturi tube 17. In most cases, when there is too much rain or the water rises and overflows the suspension ball 19, the suspension ball 19 will float up, and at the same time, it will take the sealing plug 21 away from the middle of the Venturi tube 17. Under the action of the repulsive force, the sealing plug 21 cannot fall down, and the water in and around the vegetation layer 4 is quickly sucked into the Venturi tube 17, and then discharged into the drainage pipe 18, and then enters the slide and flows into the receiving groove 5; the Venturi tube 17 serves as the first line of defense to reduce soil loss, and the gravel and muddy water falling into the receiving groove 5 will also cause part of the soil to settle, which serves as the second line of defense, thereby achieving the purpose of slope protection and reinforcement; due to the elastic force The elastic metal mesh 28 has a certain elasticity. When the suspension ball 19 floats, it will pull up the elastic metal mesh 28 from the middle, and then pull up the fixed rod 13, and the fixed rod 13 will pull up the movable column 10. The elastic sleeve 9 has elasticity, so it allows the movable column 10 to have a certain degree of inclination, and it will also play a certain blocking and buffering role on the up and down movement of the movable column 10; the movable column 10 drives the limit block 15, and the limit block 15 compresses the spring 16. The upward movement of the movable column 10 is blocked by the spring 16. The buffering effect of the spring 16 combined with the elasticity of the elastic metal mesh 28 itself allows the elastic metal mesh 28 to go with the flow to a certain extent, greatly reducing the force of the elastic metal mesh 28 being pulled when facing flooding or heavy rain due to the rapid flow rate of the river, preventing excessive deformation, and improving the service life of the elastic metal mesh 28.

Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
