Description
Technical Field
[0001] This invention relates to an energy dissipation and drainage slope protection structure, and more particularly to an energy dissipation and drainage slope protection structure for the treatment of steep slopes, belonging to the field of slope engineering structure design and construction technology. Background Technology
[0002] Terminology Explanation Drainage ditch: A ditch that intercepts water flowing down a slope to the lower slope or building and directs the water to a suitable location.
[0003] The necessity of energy dissipation in drainage ditches is that for steep slopes, it is common for the water diversion height difference of drainage ditches to reach 100m to 200m. Energy dissipation of the steep water flow under this height difference can effectively increase the service life of the drainage ditch structure and also better control the water flow in the drainage ditch.
[0004] The shortcomings of existing conventional energy dissipation technologies are as follows: 1. Energy dissipation in a stilling basin, such as... Figure 4 The diagram shows a common structure for stilling basins, typically with one level spaced 20-30m apart, usually located in gentle slopes. However, for steep slopes, it is generally difficult to find suitable locations for stilling basins. 2. Stepped energy dissipation, such as Figure 5 The diagram shows a common stepped energy dissipation structure, which is generally evenly arranged along the axis of the drainage ditch. Due to its weak energy dissipation capacity, it is usually arranged in a long length and has poor economic efficiency. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide an energy dissipation drainage slope protection structure with good energy dissipation effect and suitable for arrangement in slope drainage ditches for the treatment of high and steep slopes.
[0006] The technical solution adopted to solve the above-mentioned technical problems is: an energy dissipation and drainage slope protection structure for high and steep slope treatment, including a high and steep slope body, on which a drainage ditch extending along the slope direction is set. The energy dissipation and drainage slope protection structure also includes at least one set of self-energy dissipation drainage and conveying mechanisms. Each set of self-energy dissipation drainage and conveying mechanisms includes a group of inclined guide plates and a hook-type guide energy dissipation structure. Each set of self-energy dissipation drainage and conveying mechanisms is arranged sequentially in the drainage ditch along the inclined length direction. The high-speed water flow passing through the self-energy dissipation drainage and conveying mechanisms is decelerated and dissipated by the collision between the inclined guide plates and the hook-type guide energy dissipation structure. During the slope drainage process, the downstream water flow with a flow velocity exceeding the specified water conveyance velocity is dissipated in stages by the self-energy dissipation drainage and conveying mechanisms at the corresponding positions and the flow velocity is reduced to the specified water conveyance velocity.
[0007] Furthermore, at least two drainage ditches shall be installed along the length of the steep slope, with the distance between two adjacent drainage ditches not exceeding 150m.
[0008] The preferred method of the above scheme is that the distance between two adjacent sets of self-energy-dissipating drainage and conveying mechanisms in the same drainage ditch does not exceed 30m.
[0009] Furthermore, the inclined guide plate assembly includes multiple inclined guide plates, which are arranged alternately in the middle of the drainage ditch along its width. The reverse hook energy dissipation structure includes multiple sets of semi-V-shaped reverse hooks, which are arranged in the drainage ditch on both sides through the side walls and the corresponding inclined guide plates. The water flowing down the drainage ditch flows downward at an angle through the inclined guide plates. A portion of the downward flowing water is guided back by the corresponding semi-V-shaped reverse hooks and dissipates energy, slows down, and flows downward during the collision with the downward flowing water guided by the inclined guide plates.
[0010] The preferred embodiment of the above scheme is that each group of inclined guide vanes includes six to eight inclined guide vanes, and each inclined guide vane is arranged sequentially in the middle of the drainage ditch along its width, with the first vane inclined at 40-50° and the next adjacent vane inclined at the same angle in the opposite direction. The distance between the top of the next inclined guide vane and the middle of the adjacent previous inclined guide vane is consistent with the distance between the top of the corresponding reverse hook energy dissipation structure inserted into the inclined guide vane group and the upper middle part of the previous inclined guide vane. During the process of the water flowing down the drainage ditch being guided down through the two guide surfaces above and below each inclined guide vane and the upper surface of the corresponding inclined guide vane, the water impacts and dissipates energy with the return water guided by the reverse hook energy dissipation structure, decelerates, and flows down.
[0011] Furthermore, the reverse hook-type guiding energy dissipation structure includes multiple sets of semi-V-shaped reverse hooks, with a number comparable to that of the inclined guide plates. Each set of semi-V-shaped reverse hooks has a smoothly transitioned bottom guide surface at its bottom. The top of the hook edge of each set of semi-V-shaped reverse hooks that is not connected to the sidewall has a smoothly transitioned top guide surface. With the cooperation of the sidewall, each semi-V-shaped reverse hook arranged in the drainage ditches on both sides inserts its hook edge between two inclined guide plates at the corresponding position. The distance between the top of each hook edge and the upper wall of the corresponding inclined guide plate is consistent with the distance between the wall and end face of the corresponding two inclined guide plates. A portion of the inclined downward flow is guided back by the bottom guide surface and then collides with the water flowing down along the lower side of the corresponding inclined guide plate to dissipate energy, slow down, and then flow down.
[0012] The preferred embodiment of the above scheme is that a bottom flow sill is also provided in the drainage ditch at the end of each set of self-energy dissipating drainage and conveying mechanisms.
[0013] Furthermore, the bottom flow sill is arranged in a stepped shape in the drainage ditch between two adjacent sets of self-energy-dissipating drainage and conveying mechanisms.
[0014] The beneficial effects of this invention are as follows: The technical solution provided in this application is based on the existing high and steep slope body, and combined with the structural feature of setting up drainage ditches extending along the slope direction on the high and steep slope body, the energy dissipation drainage slope protection structure of this application is constituted by adding at least one set of self-energy dissipation drainage and conveying mechanisms. Each set of self-energy dissipation drainage and conveying mechanisms includes a group of inclined guide plates and a hook-type guide energy dissipation structure. Then, each set of self-energy dissipation drainage and conveying mechanisms is arranged sequentially in the drainage ditch along the inclined length direction of the drainage ditch. The high-speed water flow passing through the self-energy dissipation drainage and conveying mechanisms is decelerated and dissipated during the collision process of the inclined guide plates and the hook-type guide energy dissipation structure. Finally, during the slope drainage process, the downstream water flow with a flow velocity exceeding the specified water conveyance speed is dissipated in stages by the self-energy dissipation drainage and conveying mechanisms at the corresponding positions and the flow velocity is reduced to the specified water conveyance speed, thereby improving the energy dissipation effect and making it suitable for arrangement in the slope drainage ditch.

[0017] like Figure 1 , Figure 2 as well as Figure 3The diagram illustrates an energy-dissipating drainage slope protection structure for high and steep slope treatment, provided by the present invention, which has good energy dissipation effect and is suitable for arrangement within slope drainage ditches. The energy-dissipating drainage slope protection structure includes a high and steep slope body, on which a drainage ditch 1 extending along the slope direction is provided. The structure also includes at least one set of self-energy-dissipating drainage conveying mechanisms 2. Each set of self-energy-dissipating drainage conveying mechanisms includes an inclined guide plate group and a hook-type guiding energy dissipation structure. The self-energy-dissipating drainage conveying mechanisms 2 are sequentially arranged in the drainage ditch 1 along the inclined length direction of the drainage ditch. High-speed water flowing through the self-energy-dissipating drainage conveying mechanisms 2 is decelerated and energy dissipated through collisions with the inclined guide plate group and the hook-type guiding energy dissipation structure. During slope drainage, downstream water with a flow velocity exceeding the specified water delivery velocity is segmented and its velocity reduced to the specified water delivery velocity by the self-energy-dissipating drainage conveying mechanisms 2 at corresponding positions. The technical solution provided in this application is based on the existing high and steep slope body, and combined with the structural characteristics of the drainage ditch extending along the slope direction on the high and steep slope body. The energy dissipation drainage slope protection structure of this application is formed by adding at least one set of self-energy dissipation drainage and conveying mechanisms. Each set of self-energy dissipation drainage and conveying mechanisms includes a group of inclined guide plates and a hook-type guide energy dissipation structure. Then, the sets of self-energy dissipation drainage and conveying mechanisms are arranged sequentially in the drainage ditch along the inclined length direction. The high-speed water flow passing through the self-energy dissipation drainage and conveying mechanisms is decelerated and dissipated by the collision between the inclined guide plates and the hook-type guide energy dissipation structure. Finally, during the slope drainage process, the downstream water flow with a flow velocity exceeding the specified water conveyance speed is dissipated in stages by the self-energy dissipation drainage and conveying mechanisms at the corresponding positions, and the flow velocity is reduced to the specified water conveyance speed, thereby improving the energy dissipation effect and making it suitable for arrangement in the slope drainage ditch. Considering the actual conditions of steep slopes, this application provides at least two drainage ditches 1 along the length of the steep slope, with the distance between two adjacent drainage ditches 1 not exceeding 150m. The distance between two adjacent sets of self-energy dissipating drainage and conveying mechanisms 2 within the same drainage ditch 1 does not exceed 30m.
[0018] Accordingly, in order to facilitate construction and maximize the energy dissipation effect while reducing the scouring damage to the slope caused by high-speed water flow, the inclined guide plate group of this application includes multiple inclined guide plates 3. Each inclined guide plate 3 is arranged alternately in the middle of the drainage ditch 1 along the width direction. The reverse hook energy dissipation structure includes multiple sets of semi-V-shaped reverse hooks 4. Each set of semi-V-shaped reverse hooks 4 is arranged in the drainage ditch 1 on both sides through the side walls 5 on both sides of the drainage ditch 1 and the inclined guide plates 3 at the corresponding positions. The water flowing down the drainage ditch 1 flows downward at an angle through the inclined guide plates 3. A part of the inclined downward water flow is guided back by the semi-V-shaped reverse hooks 4 at the corresponding positions and dissipates energy, decelerates and flows down during the collision with the inclined downward water flow guided by the inclined guide plates 3.
[0019] More specifically, each set of inclined guide plates includes six to eight inclined guide plates 3. The inclined guide plates 3 are arranged sequentially in the middle of the width of the drainage ditch 1, with the first plate inclined at 40-50° and the next one inclined at the same angle in the opposite direction. The distance between the top of the next inclined guide plate 3 and the middle of the adjacent previous inclined guide plate 3 is consistent with the distance between the top of the corresponding half-V-shaped reverse flow hook 4 inserted into the inclined guide plate set and the upper middle part of the previous inclined guide plate 3. During the process of the water flowing down the drainage ditch 1 being guided down through the two guide surfaces above and below each inclined guide plate 3 and the upper end surface of the corresponding inclined guide plate 3, the water impacts and dissipates energy with the return water guided by the reverse flow hook energy dissipation structure, decelerates and flows down. Each set of reverse hook energy dissipation structure includes multiple sets of semi-V-shaped reverse hooks 4, the number of which is equivalent to the number of inclined guide plates 3. Each set of semi-V-shaped reverse hooks 4 has a smoothly transitioned hook bottom guide surface 6 at its bottom. The top of the hook edge of each set of semi-V-shaped reverse hooks 4 that is not connected to the side wall 5 has a smoothly transitioned hook top guide surface 7. With the cooperation of the side wall 5, each semi-V-shaped reverse hook 4 arranged in the drainage ditches on both sides is inserted between two inclined guide plates 3 at the corresponding position through its hook edge. The distance between the top of each hook edge and the upper wall of the corresponding inclined guide plate 3 is consistent with the distance between the wall and end face of the corresponding two inclined guide plates 3. A part of the inclined downward flow is guided back through the hook bottom guide surface 6 and then collides with the water flowing down along the lower side of the corresponding inclined guide plate 3 to dissipate energy, slow down and flow down.
[0020] Furthermore, a bottom flow buffer 8 is also provided in the drainage ditch at the end of each set of self-energy dissipation drainage and conveying mechanisms. In this case, the bottom flow buffer 8 is arranged in a stepped shape in the drainage ditch between two adjacent sets of self-energy dissipation drainage and conveying mechanisms.
[0021] In summary, the technical solution provided in this application also has the following advantages: 1) It can be placed anywhere in the drainage ditch, without being restricted by steep slopes; 2) High energy dissipation efficiency, only requires interval arrangement, and is economical.
[0022] The technical solution of this application will be further described below through specific embodiments: The technical problem to be solved by the present invention is to provide an efficient energy dissipation structure for drainage ditches.
[0023] The technical solution adopted by this invention to solve the technical problem is as follows: In drainage ditches on steep slopes, energy dissipation zones are set up according to equal or unequal elevation differences, and each energy dissipation zone consists of two structural parts. Wherein: 1) The sidewall backflow hook structure is mainly used to push the water flowing on the structure upwards to the middle of the drainage ditch and to dissipate energy by impact with the water coming from the upper part of the outlet. 2) The middle flow guiding structure mainly functions to divide the upstream water into two streams: one flows downward naturally, and the other flows towards the side wall cantilever structure and then hooks back to form an impact water flow that collidees with the downward naturally flowing water flow to dissipate energy.
