[0003] However, when the existing reinforcement device is built on the mudstone soil layer, if it rains heavily, a large amount of water will seep into the mudstone soil layer due to the erosion of rainwater along the slope and the retention of rainwater in the reinforced structure. The mudstone itself has a low strength, so when water seeps in, it will make the mudstone more easily softened, resulting in landslide instability. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and method for reinforcing a bedding sandstone slope, which solves the problem that when the existing reinforcement device is built on a mudstone soil layer, the mudstone is more likely to soften and loosen due to water seepage, resulting in landslide and instability.

DETAILED DESCRIPTION

[0027] The following combination Figures 1 to 8 The present invention is described in detail.

[0028] A device for reinforcing a bedding sandstone and mudstone slope comprises a slope 1, a reinforcement layer 2 is provided on the surface of the slope 1, a collection opening 201 is provided on the top surface of the reinforcement layer 2, a water flow trough 202 is provided at the middle bottom of the reinforcement layer 2, a water flow cavity 203 is provided inside the reinforcement layer 2, a lifting groove 2031 is provided on one side of the middle of the water flow cavity 203, a deflection assembly is connected to the middle of the water flow cavity 203, the deflection assembly moves and swings along the lifting groove 2031, a water collection pipe 205 is provided on one side of the reinforcement layer 2, and a piston rod 2051 is connected to the inside of the water collection pipe 205. One end of the piston rod 2051 is provided with a piston that cooperates with the water collecting pipe 205. The end of the piston rod 2051 away from the piston is connected to the deflection assembly. The collection opening 201 is an opening that extends obliquely from the surface of the reinforcement layer 2 to the water flow chamber 203. The water flow trough 202 also includes a barrier net 2021 and a diverter block 2022. Both ends of the water flow trough 202 are connected to the water flow chamber 203. The barrier net 2021 is arranged at the opening of the water flow trough 202, and the diverter block 2022 is arranged at the middle bottom of the water flow trough 202. The diverter block 2022 is a triangular shaped protrusion.

[0029] First, the reinforcement layer 2 is built on the surface of the slope 1 to reinforce the slope 1. Then, on rainy days, when water flows along the surface of the slope 1 and drips on the reinforcement layer 2, it will be collected through the collection opening 201 and the water flow trough 202, allowing the rainwater to flow into the water flow cavity 203 and then accumulate on the water accumulation plate 204, so as to prevent the water from scouring the surface of the slope 1 and causing a large amount of infiltration into the soil layer, thereby avoiding some sand and mudstone soil layers with low soil strength, which are easily softened by water and cause landslides and instability.

[0030] Furthermore, the lifting groove 2031 includes a deflection groove 2032, a telescopic rod 2033 and a slide groove 2034. The deflection groove 2032 is a groove arranged on one side of the bottom of the lifting groove 2031, the telescopic rod 2033 is arranged at the top of the lifting groove 2031, and the slide groove 2034 is arranged on both sides of the middle part of the lifting groove 2031. The telescopic rod 2033 is two rod bodies with different diameters that are embedded together, and the two rod bodies of the telescopic rod 2033 are connected by a spring. The deflection assembly includes a water accumulation plate 204 and a connecting rod 2041. The water accumulation plate 204 is a plate that is matched and connected in the water flow chamber 203, and the connecting rod 2041 is arranged on the top of the water accumulation plate 204.

[0031] At the same time, when a certain amount of water accumulates on the water accumulation plate 204, the increase in the amount of water causes the weight to force the water accumulation plate 204 to move downward along the lifting groove 2031. After moving downward to a certain distance, it will move to the position of the deflection groove 2032, allowing the water accumulation plate 204 to rotate along the slide groove 2034 through the circular axis on the protrusion on one side, so that the other side of the water accumulation plate 204 will be separated from the inner wall of the water flow cavity 203, allowing the accumulated water to flow out, and the arc setting on the other side of the water accumulation plate 204 can prevent interference during the deflection process.

[0032] Furthermore, a convex block is provided on one side of the water accumulation plate 204 to cooperate with the lifting groove 2031, and circular shaft protrusions are provided on both sides of the convex block on one side of the water accumulation plate 204 to cooperate with the slide groove 2034, and the top of the convex block on one side of the water accumulation plate 204 is connected to the bottom of the telescopic rod 2033 through a traction rope, and the two ends of the connecting rod 2041 are respectively hinged on the water accumulation plate 204 and one end of the piston rod 2051. The water collection pipe 205 also includes a water collection hole 2052, a flow opening 2053, and a limiting slide groove. 2054 and a limiting slider 206, the water collection hole 2052 is a hole with a grid set on the side wall of the water collection pipe 205, the flow opening 2053 is set on one side of the water collection pipe 205, the limiting groove 2054 is set on one side of the piston rod 2051, the limiting slider 206 is set on the side of the water flow chamber 203 connecting the hole of the water collection pipe 205, and the limiting slider 206 cooperates with the limiting groove 2054, and the flow opening 2053 is an opening on the bottom side of the water collection pipe 205.

[0033] By moving the water accumulation plate 204 downward, the piston rod 2051 can be dragged out of the water collection pipe 205 through the connecting rod 2041. When the piston rod 2051 is displaced, it will drive the piston at one end to be pulled out of the water collection pipe 205. When it is pulled out, a suction force similar to that of a syringe will be generated to attract and collect the water flow infiltrating into the soil layer through the water collection holes. The water collection holes arranged in the grid can also effectively block sand, gravel, soil, etc.

[0034] At the same time, after the piston rod 2051 is sucked and displaced to a certain distance, the piston will move to the flow opening 2053, and the sucked water will flow out directly through the flow opening 2053 and be discharged together with the deflection of the water accumulation plate 204. At the same time, the water collecting pipe 205 is tilted upward, so that the piston rod 2051 can be pulled out better and the water can be discharged along the slope.

[0035] Finally, when the water accumulation plate 204 is reset, it will drive the piston rod 2051 to reset together, so that the water collection hole 2052 produces a blowing effect, which will affect the movement of the mud and sand attached to the grid of the water collection hole 2052 and will not be blocked in the water collection hole 2052 all the time, so that the water collection pipe 205 can be repeatedly sucked.

[0036] The following is a specific process for implementing the present invention. First, the reinforcement layer 2 is built on the surface of the slope 1 to reinforce the slope 1. Then, on rainy days, when water flows along the surface of the slope 1 and drips on the reinforcement layer 2, it will be collected through the collection opening 201 and the water flow trough 202, allowing the rainwater to flow into the water flow cavity 203, and then accumulate on the water accumulation plate 204 to prevent the water from scouring the surface of the slope 1, causing a large amount of infiltration into the soil layer, and avoiding the occurrence of landslide instability due to the low soil strength of some sand and mudstone layers, which are easily softened by water. At the same time, when a certain amount of water accumulates on the water accumulation plate 204, the weight will force the water accumulation plate 204 to move due to the increase in water volume. 4 will move downward along the lifting groove 2031, and after moving downward to a certain distance, it will move to the position of the deflection groove 2032, allowing the water accumulation plate 204 to rotate along the slide groove 2034 through the circular axis on the protrusion on one side, so that the other side of the water accumulation plate 204 will be separated from the inner wall of the water flow cavity 203, allowing the accumulated water to flow out, and the arc setting on the other side of the water accumulation plate 204 can prevent interference during the deflection process. By moving the water accumulation plate 204 downward, the piston rod 2051 can be dragged out of the water collecting pipe 205 through the connecting rod 2041. When the piston rod 2051 is displaced, it will drive the piston at one end to be drawn out of the water collecting pipe 205, and When the water is drawn out, a suction force similar to that of a syringe will be generated to attract and collect the water infiltrating into the soil layer through the water collection holes, and the water collection holes arranged in the grid can also effectively block sand, gravel, mud, etc. At the same time, after the piston rod 2051 is sucked and displaced to a certain distance, the piston will move to the flow opening 2053, and the sucked water will flow out directly through the flow opening 2053 and be discharged together with the deflection of the water accumulation plate 204. After the drainage is completed, the water accumulation plate 204 will be reset through the telescopic rod 2033, and the water accumulation plate 204 is connected to the telescopic rod 2033 by a traction rope, so that the deflection of the water accumulation plate 204 will not drive the telescopic rod 2033 to deflect together The water accumulation plate 204 will be deflected and reset again through the pressure exerted by the deflected inclination angle and the edge corners, and this process will be easier the more water is discharged, so as to slow down the speed of reset deflection and give the water more time to be discharged. Finally, when the water accumulation plate 204 is reset, it will drive the piston rod 2051 to reset together, so that the water collection hole 2052 will produce a blowing effect, which will affect the movement of mud and sand attached to the grid of the water collection hole 2052 and will not be blocked in the water collection hole 2052 all the time, so that the water collection pipe 205 can be repeatedly sucked.
