DETAILED DESCRIPTION
[0034] In order to facilitate the person skilled in the art to understand, the utility model is further explained below in combination with the drawings.
[0035] Please refer to Figure 1 , Figure 2 , one embodiment of the reservoir slope protection reinforcing device provided by the utility model, including protective net 1 and buffer pile 2, buffer pile 2 fixes protective net 1 on the slope of reservoir. Among them, the protective net includes several warps 11 and several wefts 12, and the warp 11 and the weft 12 are cross set, and the two can be woven into one, or can be split type, and are fixed on the slope by buffer pile 2 respectively.
[0036] As Figure 3 shown in the drawings, the buffer pile 2 comprises a buffer sleeve 21 and a pile shaft 22. As Figure 4 shown in the drawings, the buffer sleeve 21 comprises a connecting plate 211, the middle part of the connecting plate 211 is provided with a through hole, the connecting plate 211 is provided with a plurality of flaps 212, the plurality of flaps 212 surrounds the outside of the through hole, and a wire slot 213 is formed between adjacent two flaps 212 for the warp 11 or weft 12 to pass through. The flaps 212 are preferably located at the outer edge of the connecting plate 211, and the connecting plate 211 can be of any shape, such as a rectangular plate, a polygonal plate, etc.; the connecting plate 211 is preferably circular, and the flaps 212 are arc-shaped. The number of flaps 212 is preferably 2-4, thereby forming 2-4 wire slots 213.
[0037] The pile shaft 22 is inserted into the soil at one end in use, and the other end exposed to the soil is the buffer end, and the buffer sleeve 21 is sleeved on the buffer end of the pile shaft 22. The pile shaft 22 comprises an insertion part 222 and a buffer part 221, which are connected as one body. The buffer part 221 corresponds to the buffer end of the pile shaft 22, and the insertion part 222 corresponds to the insertion end of the pile shaft; the outer contour size of the buffer part 221 is larger than the inner diameter of the through hole, and the outer contour size of the insertion part 222 is smaller than the inner diameter of the through hole, the buffer part 221 is located in the buffer sleeve 21, and the insertion part 222 extends out of the buffer sleeve 21 through the through hole.
[0038] In use, the insertion part 222 is inserted into the soil to be fixed, and the buffer sleeve 21 is pressed on the slope by the buffer part 221; the warp 11 or weft 12 can enter the buffer sleeve 21 from one wire slot 213 and extend out of another wire slot 213; as Figure 6 shown in the drawings, the warp 11 or weft 12 can enter and exit the buffer sleeve 21 from two adjacent wire slots 213, or as Figure 7 shown in the drawings, the warp 11 or weft 12 can enter and exit the buffer sleeve 21 from two wire slots 213 arranged at intervals. The warp 11 or weft 12 can also enter and exit the buffer sleeve 21 from the same wire slot 213. The part of the warp 11 or weft 12 located in the buffer sleeve 21 is clamped between the connecting plate 211 and the buffer part 221, and is wound around the outside of the pile shaft 22, and the wrap angle is as large as possible, and the connection of the buffer pile 2 is more reliable. The warp 11 or weft 12 can be tensioned by using two or more buffer piles 2, thereby achieving the fixation of the protective net 1.
[0039] The buffering pile 2 is preferably made of a corrosion-resistant material with a certain elastic deformation amount. When the water flow impacts on the outer wall of the baffle 212, the baffle 212 is elastically deformed to buffer the impact of the water flow. It can be understood that the number of pile shafts 22 is appropriately increased, which can improve the protection stability and buffering effect; when the warp 11 and the weft 12 are pre-woven into one body, a relatively large number of buffering piles 2 can be arranged in the lower area of the slope protection, for example, near the normal water level of the reservoir. The arrayed and staggered buffering piles 2 can effectively buffer the impact of the water flow; and for the position of the upper part of the slope protection which is generally not reached by the water level, the number of pile shafts 22 can be correspondingly reduced, so as to balance the use cost and the protection effect.
[0040] In order to facilitate the later maintenance of the device, the pile shaft 22 is designed in a split type, and the insertion part 222 and the buffering part 221 are connected by threads. The outer wall of the insertion part 222 can also be provided with a rotating piece 225, which facilitates the construction of the insertion part 222 and can prevent loosening.
[0041] Further, the insertion part 222 and the buffering part 221 are preferably cylindrical, the outer diameter of the insertion part 222 is smaller than that of the buffering part 221, and both are coaxially arranged. A wire platform 223 is arranged between the buffering part 221 and the insertion part 222, the outer diameter of the wire platform 223 is greater than that of the insertion part 222 and smaller than that of the buffering part 221. The wire platform 223 separates the connecting plate 21 and the buffering part 221 by a certain distance to accommodate the warp 11 and / or the weft 12; the axial dimension of the wire platform 223 is 4-8 mm, which can meet the fixing requirements of most protection nets 1 on the market.
[0042] The outer wall of the buffering part 221 is provided with a plurality of recesses 224, and the plurality of recesses 224 are arranged at intervals in the circumferential direction of the buffering part 221. The baffle 212 is provided with a plurality of radially inwardly protruding protrusions 214, the positions of the protrusions 214 and the recesses 224 correspond one by one, the protrusions 214 extend into the recesses 224, and the protrusions 214 and the recesses 224 are gap-fitted. The arrangement of the protrusions 214 and the recesses 224 not only facilitates the replacement of the warp 11 and the weft 12 during the later maintenance, but also enables the warp 11 and the weft 12 to enter between the connecting plate 21 and the buffering part 221 through the gap between the protrusions 214 and the recesses 224 and complete the limiting without disassembling the buffering pile 2; and further, the arrangement can avoid the sliding of the warp 11 or the weft 12 from the pile shaft 22.
[0043] Further, the gap between the protrusions 214 and the recesses 224 forms a shunt water channel 23, the protrusions 214 are provided with water passing holes 215, the water passing holes 215 penetrate the inner and outer side surfaces of the protrusions 214; the fitting surfaces of the recesses 224 and the protrusions 214 are spherical surfaces, the water flow enters the buffering sleeve 21 after being preliminarily buffered by the baffle 212, and is discharged to the four sides of the water passing holes 215 through the shunt water channel 23, so as to further buffer the impact of the water flow.
[0044] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
