Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of river water conservancy projects, and more specifically, to a river water conservancy slope protection. Background Art
[0002] In existing river water conservancy projects, cement blankets are widely used due to their ease of construction and good adaptability to various terrains. With their unique materials and structures, cement blankets can fit the different forms of river banks and provide effective slope protection for rivers. However, the current application of cement blankets still faces some technical difficulties and practical challenges.
[0003] First, the existing technology is relatively simple in the way of fixing the cement blanket. This simple fixing method may not be able to remain stable in the face of extreme climate or strong water flow impact, resulting in displacement or damage of the cement blanket, affecting the effect and safety of slope protection. In addition, the simple fixing method is also easily weakened by long-term water and soil erosion, which in turn affects the service life of the cement blanket and the slope protection effect.
[0004] Secondly, the fixing process of cement blanket usually requires the use of various tools, among which handwheels are commonly used as auxiliary tools. However, most handwheels are connected to the fixing device with a fixed structure, which is easy to cause artificial damage or theft of the handwheel. This not only increases the maintenance cost, but also may affect the progress and quality of construction due to the lack of tools.
[0005] Furthermore, when the water content of the riverbank soil is too high, the fixing effect of the cement blanket will be affected. When the soil is moist or has too much water, it is difficult for the fixing device to be firmly inserted into the soil, thus affecting the stability of the entire slope protection structure. In extreme cases, it may even cause the cement blanket to slip or collapse as a whole, posing a serious threat to the safety of the riverbank. Although some existing technologies use drainage pipes to remove moisture from the soil, these drainage structures are often simple in structure and cannot effectively filter the silt in the soil. This simple drainage facility may become blocked when faced with a large amount of silt, thereby losing the drainage effect, further exacerbating the instability of the slope protection structure.

[0032] See also Figure 1-6A river channel water conservancy slope protection comprises a cement blanket 1, on which a fixing device is arranged, the fixing device comprising a fixing sleeve 2, a connecting rod 3, a diffusion rod 4, a limiting groove 5, a screw sleeve 6, a rotating sleeve 7, a screw 8 and a rotating rod 9, the fixing sleeve 2 is mounted on the cement blanket 1, the rotating rod 9 is movably mounted on the inner side of the fixing sleeve 2, the screw 8 is fixedly connected to one end of the rotating rod 9, the screw sleeve 6 is movably mounted on the outer side of the screw 8 through a thread, the limiting groove 5 is opened on the side wall of the fixing sleeve 2, the rotating sleeve 7 is movably sleeved on the side wall of the rotating rod 9, one end of the diffusion rod 4 is movably connected to the rotating sleeve 7, one end of the connecting rod 3 is movably connected to the screw sleeve 6, and the other end of the connecting rod 3 is connected to the diffusion The rod 4 is movably connected, and the diffusion rod 4 is in the limiting groove 5. A handwheel 10 is provided at the top of the rotating rod 9, and a clamping device is connected to one end of the handwheel 10. The clamping device includes a connecting rod 11, a limiting sleeve 12, a clamping groove 13, a yielding groove 14, a plug-in groove 15 and a ball 16. The connecting rod 11 is fixedly connected to one side of the handwheel 10, the plug-in groove 15 is opened at the top of the rotating rod 9, and one end of the connecting rod 11 extends into the plug-in groove 15. The limiting sleeve 12 is movably sleeved on the outside of the connecting rod 11, and the ball 16 is movably installed in the limiting sleeve 12. The clamping groove 13 is opened on the side wall of the plug-in groove 15, and the yielding groove 14 is opened on the side wall of the connecting rod 11.
[0033] A fixing rod 17 is disposed at the top of the fixing sleeve 2 , and a ground nail 18 is disposed on the fixing rod 17 .
[0034] A second spring 19 is disposed inside the limiting sleeve 12 , and one end of the second spring 19 is connected to the connecting rod 11 .
[0035] A rubber sleeve 20 is disposed on the outer side of the hand wheel 10 .
[0036] In this embodiment, when using the device, the cement blanket 1 is first laid on the river channel slope, and then the fixing sleeve 2 is passed through the cement blanket 1 and hammered into the soil until the lower end surface of the fixing rod 17 and the soil stably fix the cement blanket 1, and at the same time, the ground nail 18 set at one end of the fixing rod 17 will also enter the ground, thereby nailing the cement blanket 1 to the ramp, and then the hand wheel 10 is taken out, and the connecting rod 11 is pulled outward, so that the ball 16 enters the give way groove 14 opened on the side wall of the connecting rod 11, and at the same time, the connecting rod 11 will compress the second spring 19 arranged inside the limiting sleeve 12, and then insert the limiting sleeve 12 and the connecting rod 11 into the insertion groove 15 opened at the top of the rotating rod 9. When the ball 16 enters the insertion groove 15, it will no longer apply a tensile force to the connecting rod 11, and directly press it inward. When the position of the ball 16 corresponds to the position of the card slot 13, the second spring 19 will automatically reset, so that the connecting rod 11 moves in the limiting sleeve 12, and the ball 16 will roll out of the giving way groove 14, and then the ball 16 will roll out of the giving way groove 14. The ball 16 will be squeezed and thus engage into the slot 13, thereby firmly engaging the hand wheel 10 at one end of the rotating rod 9, and then the hand wheel 10 is rotated in the corresponding direction. The rubber sleeve 20 wrapped around the outside of the hand wheel 10 can improve the operator's feel and increase the friction. Then the rotating rod 9 will rotate. Due to the limiting effect of the limiting groove 5, the rotating sleeve 7 and the screw sleeve 6 will not rotate with the rotating rod 9. Then the rotating rod 9 will drive the screw 8 to rotate together. Since the screw sleeve 6 and the screw 8 are movably connected through threads, The screw sleeve 6 is limited in the lateral direction, so the screw sleeve 6 will move up and down accordingly on the outside of the screw rod 8. Since the two ends of the connecting rod 3 are movably connected to the diffusion rod 4 and the screw sleeve 6 respectively, the screw sleeve 6 will drive the diffusion rod 4 to slowly diffuse outward through the connecting rod 3 while moving, so that the fixation of the cement blanket 1 is more stable and less likely to fall off. When the hand wheel 10 can no longer be rotated, the hand wheel 10 is directly pulled outward, and the limiting sleeve 12 and the connecting rod 11 are detached from the inside of the plug-in slot 15 by referring to the above process.
[0037] See also Figure 1-3 As a river water conservancy slope protection implementation method for the drainage device: the drainage device includes a drainage pipe 21 and a filter cartridge 22, the drainage pipe 21 is arranged on the outside of the fixed sleeve 2, and the filter cartridge 22 is detachably installed on the inside of the drainage pipe 21.
[0038] A sealing plate 23 is provided inside the drain pipe 21 .
[0039] A first spring 24 is disposed inside the drain pipe 21 , and one end of the first spring 24 is connected to the sealing plate 23 .
[0040] A sealing cover 25 is provided at one side of the drain pipe 21 , and the sealing cover 25 is detachably mounted on one end of the drain pipe 21 through threads.
[0041] More specifically, before the cement blanket 1 is fixed to the ramp, the drain pipe 21 can be pre-buried in the corresponding position in the soil, and then the cement blanket 1 is fixed to the ramp, and then the filter cartridge 22 is inserted into the drain pipe 21, and then one end of the filter cartridge 22 will push against the sealing plate 23 set on the inner side of the drain pipe 21, so that the sealing plate 23 is opened, and the sealing plate 23 will compress the first spring 24 set on one side, and then the sealing cover 25 is screwed to one side of the drain pipe 21 to prevent the filter cartridge 22 from being pushed out of the inner side of the drain pipe 21. When there is too much moisture in the soil, the moisture can be discharged through the drain pipe 21, which is effective. To prevent the ramp from collapsing or being loosely fixed, the filter cartridge 22 can effectively filter the silt and prevent it from entering the inside of the drain pipe 21 and clogging it. When the equipment is used for a long time and the filter cartridge 22 needs to be replaced, the cover 25 is unscrewed and the filter cartridge 22 is taken out from the inside of the drain pipe 21. During this process, the first spring 24 will reset and push the sealing plate 23 to move. When the filter cartridge 22 is pulled out of the drain pipe 21, the sealing plate 23 has closed the drain pipe 21 to prevent silt from entering the inside of the drain pipe 21. Then the new filter cartridge 22 is installed into the drain pipe 21 according to the above process.
[0042] In summary, when the overall equipment is in use or running: first, the cement blanket 1 is laid on the river channel slope, and then the fixing sleeve 2 is passed through the cement blanket 1, and the fixing sleeve 2 is hammered into the soil until the lower end surface of the fixing rod 17 and the soil stably fix the cement blanket 1, and at the same time, the ground nail 18 set at one end of the fixing rod 17 will also enter the ground, thereby nailing the cement blanket 1 to the ramp, and then take out the hand wheel 10, pull the connecting rod 11 outward, so that the ball 16 enters the give way groove 14 opened on the side wall of the connecting rod 11, and at the same time connects The rod 11 will compress the second spring 19 provided inside the limiting sleeve 12, and then insert the limiting sleeve 12 and the connecting rod 11 into the insertion groove 15 opened at the top of the rotating rod 9. When the ball 16 enters the insertion groove 15, it will no longer exert a tensile force on the connecting rod 11, and directly press inward. When the position of the ball 16 corresponds to the position of the card slot 13, the second spring 19 will automatically reset, so that the connecting rod 11 moves in the limiting sleeve 12, and the ball 16 will roll out of the yielding groove 14, and then The ball 16 will be squeezed and thus engage into the slot 13, thereby firmly engaging the hand wheel 10 at one end of the rotating rod 9, and then the hand wheel 10 is rotated in the corresponding direction. The rubber sleeve 20 wrapped around the outside of the hand wheel 10 can improve the operator's feel and increase the friction. Then the rotating rod 9 will rotate. Due to the limiting effect of the limiting groove 5, the rotating sleeve 7 and the screw sleeve 6 will not rotate with the rotating rod 9. Then the rotating rod 9 will drive the screw 8 to rotate together. Since the screw sleeve 6 and the screw 8 are movably connected through threads, The screw sleeve 6 is limited in the lateral direction, so the screw sleeve 6 will move up and down accordingly on the outside of the screw rod 8. Since the two ends of the connecting rod 3 are movably connected to the diffusion rod 4 and the screw sleeve 6 respectively, the screw sleeve 6 will drive the diffusion rod 4 to slowly diffuse outward through the connecting rod 3 while moving, so that the fixation of the cement blanket 1 is more stable and less likely to fall off. When the hand wheel 10 can no longer be rotated, the hand wheel 10 is directly pulled outward, and the limiting sleeve 12 and the connecting rod 11 are detached from the inside of the plug-in slot 15 by referring to the above process.
[0043] Before fixing the cement blanket 1 to the ramp, the drainage pipe 21 can be pre-buried in the corresponding position in the soil, and then the cement blanket 1 can be fixed to the ramp, and then the filter cartridge 22 can be inserted into the drainage pipe 21, and then one end of the filter cartridge 22 will push against the sealing plate 23 set on the inner side of the drainage pipe 21, so that the sealing plate 23 is opened, and the sealing plate 23 will compress the first spring 24 set on one side, and then the sealing cover 25 is screwed to one side of the drainage pipe 21 to prevent the filter cartridge 22 from being pushed out of the inner side of the drainage pipe 21. When there is too much moisture in the soil, the moisture can be discharged through the drainage pipe 21, effectively preventing If the ramp collapses or is not firmly fixed, the filter cartridge 22 can effectively filter the silt and prevent it from entering the inside of the drain pipe 21 and clogging it. When the equipment is used for a long time and the filter cartridge 22 needs to be replaced, the cover 25 is unscrewed and the filter cartridge 22 is taken out from the inside of the drain pipe 21. During this process, the first spring 24 will reset and push the sealing plate 23 to move. When the filter cartridge 22 is pulled out of the drain pipe 21, the sealing plate 23 has closed the drain pipe 21 to prevent silt from entering the inside of the drain pipe 21. Then the new filter cartridge 22 is installed into the drain pipe 21 according to the above process.
