Description

Technical Field

[0001] The utility model belongs to the fields of slope protection and slope drainage, and specifically relates to a high slope protection structure. Background Technique

[0002] A slope refers to a slope with a certain gradient made on both sides of a roadbed to ensure the stability of the roadbed; when the rainfall is large, the soil on the surface layer of the mountain body is filled with water, resulting in an increase in the weight of the surface layer soil and a significant reduction in its mechanical properties, and then landslides are likely to occur. In the construction of high slope protection for railways or highways, the quality of the slope drainage system affects the durability of slope protection. Once a landslide occurs, it will trigger serious safety accidents. Currently, the drainage system for high slopes generally adopts drain pipes with holes around the perimeter to be installed in the slope to directly discharge the accumulated water in the slope, so as to reduce the water pressure in the soil in the slope, reduce the pressure on the protection body, and ensure the stability of the slope protection.

[0003] Currently, the drainage system for high slopes generally adopts drain pipes with holes around the perimeter to be installed in the slope to directly discharge the accumulated water in the slope, so as to reduce the water pressure in the soil in the slope, reduce the pressure on the protection body, and ensure the stability of the slope protection. However, the conventional slope protection and drainage methods usually can only discharge a small amount of accumulated water on the surface, with slow drainage and infiltration efficiency and a small range. According to relevant technical requirements, when the slope height is greater than 6m, skeleton protection + grass planting protection should be adopted; when the height of the granite weathered soil slope is greater than 4m, skeleton protection + grass planting protection should be adopted. Conventional slope protection and drainage facilities often only consider drainage and do not consider how to maintain the soil so that it can ensure slope safety and maintain the necessary soil humidity for plant growth. In the dry season, manual watering is often required, increasing the maintenance cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high slope protection structure to solve the problems raised in the above-mentioned prior art.

[0005] Provide a high slope protection structure, including:

[0006] A slope body, on which a protection skeleton and several grass planting grooves surrounded by the protection skeleton are laid, and a lower water diversion ditch is formed on the outer side of the bottom of the slope body;

[0007] A catchment well, which vertically penetrates the inside of the slope body;

[0008] Several regulating pipes, one ends of several of the regulating pipes are communicated with the catchment well, and the other ends penetrate the slope body and extend into the inside of the slope body, and the regulating pipes extend upward in the direction away from the catchment well;

[0009] The regulating pipe divides the inner cavity into a collection chamber and a water replenishment chamber through a partition plate. A plurality of flower holes are formed in the pipe wall of the regulating pipe located in the collection chamber, and a drainage material is filled in the water replenishment chamber.

[0010] Furthermore, the periphery of the regulating pipe is coated with a permeable layer. The permeable layer is used for solid-liquid separation. Water inside the slope can penetrate through the permeable layer into the collection chamber of the regulating pipe, while impurities such as soil will be blocked by the permeable layer to prevent them from entering the collection chamber and causing blockage.

[0011] Furthermore, the well wall of the catch pit is formed into a cylindrical structure by pouring concrete. The cylindrical structure formed by the concrete provides an impermeable independent water collection space, enhancing the structural strength of the catch pit itself. At the same time, the catch pit itself is equivalent to a pile body, having a certain fixing effect on the slope, and the frictional force with the slope soil can prevent the slope from landsliding.

[0012] Furthermore, an angle of α degrees is formed between the regulating pipe and the horizontal plane, and the α angle is 5° - 15°. In this inclined state, the collected water in the collection chamber inside the regulating pipe can flow into the catch pit by itself under the action of gravity, and the water in the catch pit can also flow into the grass planting groove under the capillary action of the drainage material, realizing the self-flow of accumulated water.

[0013] Furthermore, a water collection cavity is formed between the end of the regulating pipe and the bottom of the catch pit. The drainage material in the water replenishing chamber extends downward from the end of the regulating pipe into the water collection cavity. A drain pipe is communicated with the water collection cavity, and the drain pipe penetrates through the slope and extends to the lower diversion ditch. When the accumulated water volume in the catch pit is too large, the accumulated water will exceed the elevation of the distal end of the regulating pipe and actively flow into the slope interior through the regulating pipe, causing excessive water accumulation in the slope that cannot be discharged. Therefore, it is necessary to control the water level elevation in the catch pit through the drain pipe so that the water level is always lower than the lowest elevation position of the regulating pipe.

[0014] Furthermore, the part of the drain pipe located in the water collection cavity is formed with a bending part extending towards the bottom of the water collection cavity, and a filter screen is arranged at the port of the bending part. In the later stage of the rainwater discharge process, the siphon effect can be used to drain the water storage level to the position of the pipe orifice of the bending part, forming a certain backwashing effect on the filter screen through the change of the water level, which can effectively prevent the drain pipe from being blocked; at the same time, since the pipe orifice of the bending part faces downward, heavier particulate matters are not easy to accumulate at the pipe orifice, which also has a certain anti-blocking effect.

[0015] Furthermore, an upper diversion ditch is formed outside the top of the slope, and the top of the catch pit is communicated with the upper diversion ditch through a slow-flow pipe. When the rainfall is not large and the water storage in the catch pit is not much, a small amount of rainwater in the upper diversion ditch can also enter the catch pit through the slow-flow pipe for replenishment.

[0016] Furthermore, a maze-shaped channel is formed in the slow-flow pipeline by a number of baffle plates. When the rainfall is excessive, the water volume in the upper diversion ditch increases sharply. The baffle plates in the slow-flow pipeline play a certain blocking role on the water flow, which can relieve the pressure of the upper diversion ditch to a certain extent and prevent the water flow from entering the well too quickly from the slow-flow pipeline.

[0017] Furthermore, the upper diversion ditch and the lower diversion ditch are connected by a number of rapid-flow troughs. When the rainfall is large, resulting in a large flow rate in the upper diversion ditch, in order to prevent the rainwater in the upper diversion ditch from overflowing into the grass planting trough, the rainwater can be quickly directed to the lower diversion ditch for drainage through the rapid-flow troughs, and at the same time, the water inlet pressure of the slow-flow pipeline can be relieved.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. By extending a number of regulating pipes to various parts of the slope body, the entire section of the regulating pipe can participate in water collection and infiltration, which can increase the water collection and infiltration range of the slope body, effectively collect the accumulated water deep in the slope body, with higher water collection and infiltration efficiency and better slope stabilization effect.

[0020] 2. The water in the water collection well can penetrate into each grass planting trough through the capillary action generated by the drainage objects in the water replenishment chamber, so that the regulating pipe can not only actively collect the accumulated water in the slope but also replenish water to the green plants in the dry season, reducing the maintenance difficulty of the slope green plants.

[0021] 3. By supplying water from the inside of the slope body through the regulating pipe, it can better induce the plant roots to grow deeper into the slope, promoting the slope protection effect of the plants. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] However, there will be cases where unnecessary detailed descriptions are omitted. For example, there are cases where detailed descriptions of well-known matters are omitted and repeated descriptions of actually identical structures are omitted. This is to avoid the following description becoming unnecessarily lengthy and to facilitate the understanding of those skilled in the art. In addition, the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0032] Please refer to Figures 1-4As shown in the figure, the high-slope protection structure in the embodiment of the present utility model includes a slope body 1, a catch well 2, and a number of regulating pipes 3. A protection framework 11 and a number of grass planting grooves 12 surrounded by the protection framework 11 are laid on the slope body 1, and a lower drainage ditch 13 is formed on the outer side of the bottom of the slope body 1. The catch well 2 penetrates vertically into the slope body 1. One ends of a number of regulating pipes 3 are communicated with the catch well 2, and the other ends penetrate through the slope body 1 and extend into the slope body 1. The regulating pipes 3 extend upward in the direction away from the catch well 2. The inner cavity of the regulating pipe 3 is divided into a collection chamber 32 and a water replenishment chamber 33 by a partition plate 31. A number of flower holes 34 are formed on the pipe wall of the regulating pipe 3 located in the collection chamber 32, and a drainage material 36 is filled in the water replenishment chamber 33.

[0033] The high-slope protection structure adopts the design of arranging a catch well 2 at the top of the slope body 1, and a number of regulating pipes 3 radiating outward and upward from the lower part of the catch well 2 for water collection and infiltration and green plant water replenishment. A number of flower holes 34 are formed on the side wall of the collection chamber 32 of the regulating pipe 3. The water around the regulating pipe 3 can enter the hollow collection chamber 32 from the flower holes 34 and flow to the catch well 2 for water collection under its own gravity in the inclined posture of the regulating pipe 3. A drainage material 36 is filled in the water replenishment chamber 33 of the regulating pipe 3. The drainage material 36 is a fiber fabric, such as polyester fiber, nylon, polypropylene fiber, polyethylene fiber, aramid fiber, etc., which can produce capillary and infiltration effects on water and then drain water from a low position to a high position, and at the same time has a certain anti-corrosion performance. When the humidity in the slope body 1 is too low in the dry season, the water can be sent into the slope body 1 through the capillary action of the drainage material 36 and penetrate into each grass planting groove 12 for plant growth.

[0034] Furthermore, a permeable layer 35 is coated on the periphery of the regulating pipe 3. The permeable layer 35 can specifically be a geotextile, which can allow water to pass through and block external solid substances such as soil from entering the regulating pipe 3 and causing blockage. When it rains, the rainwater enters the slope body 1. The collection chamber 32 of the regulating pipe 3 quickly collects the rainwater in the slope. The geotextile outside the regulating pipe 3 can effectively prevent particulate matters and insects from entering the regulating pipe 3. The well wall of the catch well 2 is formed into a cylindrical structure by concrete pouring, which not only plays the role of water collection and water fixation, but also the catch well 2 itself is equivalent to a pile body and has a certain fixing effect on the slope of the slope body 1.

[0035] The adjusting pipe 3 radiates upward at an angle of 5° to 15° relative to the catch well 2, and the frictional force with the soil mass of the slope body 1 can also prevent landslides. Coupled with the protection of the protection skeleton 11 and the cooperation of plant roots, it can play a good role in slope fixation. And because the water supply of the adjusting pipe 3 to the grass planting groove 12 during the dry period comes from inside the slope body 1, it can effectively induce the plant roots to grow into the slope, promoting the slope fixation effect of the slope surface plants. The slope of the adjusting pipe 3 should not be less than 5°, and too small an inclination angle is not conducive to the water in the collection chamber 32 overcoming its own gravity and flowing into the catch well 2. And the slope of the adjusting pipe 3 should not be greater than 15°, and too large an inclination angle is not conducive to the generation of the capillary action of the drainage object 36, making it difficult to drain water to the grass planting groove 12 at a high position.

[0036] A water collection cavity 21 is formed between the end of the adjusting pipe 3 at the lowest position and the bottom of the catch well 2. The drainage object 36 in the water replenishing chamber 33 extends downward from the end of the adjusting pipe 3 into the water collection cavity 21. A drain pipe 4 is communicated with the water collection cavity 21, and the drain pipe 4 penetrates through the slope body 1 and extends to the lower diversion ditch 13. When the accumulated water volume in the catch well 2 is too much, the accumulated water will exceed the distal elevation of the adjusting pipe 3 and actively flow into the slope body 1 through the adjusting pipe 3, resulting in excessive accumulated water in the slope body 1 that cannot be discharged. Therefore, it is necessary to control the water level elevation in the catch well 2 through the drain pipe 4 so that the water level is always lower than the lowest elevation position of the adjusting pipe 3.

[0037] The part of the drain pipe 4 located in the water collection cavity 21 is formed with a bending part 41 extending towards the bottom of the water collection cavity 21, and a filter screen is arranged at the port of the bending part 41. The filter screen can block large particles from entering the drain pipe 4 to prevent the drain pipe 4 from being blocked. Rainwater flows into the catch well 2 through the collection chamber 32 for storage. When the water volume in the catch well 2 is too much, the rainwater in the well can be discharged to the lower diversion ditch 13 through the drain pipe 4. Since the bending part 41 of the drain pipe 4 inside the well bends downward, the siphon effect can be used to drain the water storage level in the catch well 2 to the pipe orifice position of the bending part 41 in the later stage of the rainwater discharge process. And when the siphon ends, the filter screen is subjected to a certain backwashing effect due to the water level change of the returned water, which can effectively prevent the drain pipe 4 from being silted up. At the same time, since the orifice of the bending part 41 faces downward, heavier particles are not easy to accumulate at the orifice, which also has a certain anti-blocking effect.

[0038] An upper diversion ditch 14 is formed on the outer side of the top of the slope body 1, and the top of the catch well 2 is communicated with the upper diversion ditch 14 through a slow flow pipe 15. When the rainfall is not large and the water storage in the catch well 2 is not much, a small amount of rainwater in the upper diversion ditch 14 can also enter the catch well 2 through the slow flow pipe 15 for replenishment, so that there is always surplus water in the catch well 2 to replenish the water replenishing chamber 33.

[0039] Please refer to Figure 2 、 Figure 4 and Figure 5As shown in the figure, a maze-shaped channel is formed in the slow-flow pipeline 15 by a number of baffle plates 16. The baffle plates 16 are divided into a number of long baffle plates and short baffle plates. When the rainfall is not heavy and the water stored in the well is not much, a small amount of rainwater in the upper diversion ditch 14 can also enter the sump 2 through the slow-flow pipeline 15 for replenishment. When the rainfall is excessive, the amount of water in the upper diversion ditch 14 increases sharply. The long baffle plates and short baffle plates in the slow-flow pipeline 15 act together to disturb the water flow to form a reverse pressure, which can relieve the drainage pressure of the upper diversion ditch 14 to a certain extent and block the water flow from entering the sump 2 too quickly through the slow-flow pipeline 15.

[0040] The upper diversion ditch 14 and the lower diversion ditch 13 are connected by a number of rapid flow channels 17. When the rainfall is large, resulting in a large flow rate in the upper diversion ditch 14, in order to prevent the rainwater in the upper diversion ditch 14 from overflowing into the grass planting groove 12, the rainwater can be quickly guided to the lower diversion ditch 13 through the rapid flow channels 17 for drainage, and at the same time, the water inlet pressure of the slow-flow pipeline 15 can be relieved.

[0041] It should be noted that this application is not limited to the above embodiments. The above embodiments are only examples, and embodiments with the same composition and the same function and effect as the technical idea within the scope of the technical solution of this application are included in the technical scope of this application. In addition, within the scope of not departing from the main idea of this application, various deformations that can be thought of by those skilled in the art are applied to the embodiments, and other ways constructed by combining some constituent elements in the embodiments are also included in the scope of this application.
