Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and more specifically, to a geotechnical engineering slope seepage prevention and drainage structure. Background Technology

[0002] In the process of geotechnical engineering construction, slope protection is of paramount importance. After the construction of slopes made of rock and soil is completed, rainwater generated by rainy weather can easily cause water seepage on the slope surface, resulting in soil loss and, in severe cases, slope collapse. Therefore, it is necessary to construct anti-seepage structures on the surface of the slope.

[0003] Patent document CN221461244U discloses a slope seepage prevention structure, including: a slope body with a water storage trough; a greening structure for planting green plants to utilize water; and a drainage structure for facilitating slope drainage. The device utilizes rainwater by placing soil in multiple planting troughs and planting green plants. When there is excessive rainfall, rainwater flows out through multiple flow holes to prevent the green plants from being overwatered and dying. The discharged rainwater and the rainwater flowing through the flow troughs enter the water storage trough and are discharged separately through multiple drainage outlets. During the discharge process, the rainwater is filtered by a filter screen installed in a fixed frame. The device recovers rainwater through multiple green plants while preventing them from being overwatered and dying, and simultaneously filters the rainwater through the filter screen while discharging it.

[0004] However, the flow holes on the planting trough are located at the top of the trough. After the rain stops, the water remaining in the planting trough can submerge most of the planting soil. Prolonged soaking can easily cause some plants to rot. The urgent problem to be solved is how to reduce the amount of water remaining in the planting trough after heavy rain, and how to keep the rainwater outside the planting trough without affecting the seepage prevention and drainage, while also using the rainwater to moisten the planting soil in the planting trough and provide water for the plants. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a seepage prevention and drainage structure for geotechnical engineering slopes, which can reduce the water remaining in the planting box, lower the probability of root rot in plants, and allow rainwater to remain outside the planting box to provide moisture for the plants.

[0006] A geotechnical engineering slope seepage prevention and drainage structure includes a concrete grid laid on the slope, an installation box inserted within the concrete grid, and a planting box detachably connected to the installation box; multiple first water passages are evenly spaced on the bottom wall of the planting box, a first filter plate is fixedly connected to the first water passage, and the first water passage is located at least three-quarters of the length from the lowest point to the highest point of the slope of the bottom wall of the planting box; a drainage box is fixedly connected to the lower end face of the installation box, a second water passage is opened at the highest point of the slope of the bottom wall of the installation box, and a drainage outlet is opened on the drainage box, the drainage outlet connecting to a drainage pipe pre-embedded in the concrete grid; and cotton strips are inserted through at least one of the first water passages.

[0007] Furthermore, the opening size of the first water passage is smaller than the opening size of the second water passage.

[0008] Furthermore, the mounting box and the planting box are set at an angle.

[0009] Furthermore, the tilt angle of both the mounting box and the planting box is thirty degrees.

[0010] Furthermore, when the rainwater level inside the installation box reaches the second water passage, the water level inside the installation box is exactly located at the first water passage.

[0011] Furthermore, multiple limiting rings are fixed to the bottom wall and lower end face of the planting box, and the cotton strip is inserted into the limiting rings.

[0012] Furthermore, a counterweight is fixed to one end of the cotton strip inside the mounting box, and a limit rod is inserted into the free end of the cotton strip inside the planting box.

[0013] Furthermore, a second filter plate is fixedly connected inside the second water passage.

[0014] Furthermore, a rubber ring is fixed to the side of the drainage pipe near the drain outlet.

[0015] Furthermore, the inner diameter of the rubber ring is the same as the inner diameter of the drain outlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] ① In this utility model, the first water passage is set at least three-quarters of the length from the lowest point to the highest point of the sloping bottom wall of the planting box, which reduces the amount of rainwater retained in the planting box and allows most of the rainwater to be discharged from the planting box in time, reducing the probability of root rot of the plants. The rainwater discharged into the planting box reaches the second water passage and then flows into the drainage box through the second water passage. It then flows into the drainage pipe through the drain outlet on the drainage box and finally flows into the water ditch at the lowest point of the slope through the drainage pipe. The planting box can retain some rainwater, which is then retained outside the planting box. By setting cotton strips, water is provided to the plants.

[0018] ② In this utility model, when the water level in the installation box reaches the second water passage, the water level in the installation box is located at the first water passage in the planting box. Since the opening size of the second water passage is larger than the opening size of the first water passage, the combination of the two points can reduce the probability of rainwater in the installation box flowing back into the planting box from the first water passage, and further reduce the probability of root rot in the plant.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0029] like Figure 1-6 As shown, a geotechnical engineering slope seepage prevention and drainage structure includes a pre-cast concrete grid 1 laid on the slope. An installation box 2 is inserted within the grid of the concrete grid 1, and a planting box 3 is detachably connected inside the installation box 2. In this embodiment, the installation box 2 and the planting box 3 are detachably connected by bolts 17. Since the concrete grid 1 is set on the slope, both the installation box 2 and the planting box 3 are inclined; in this embodiment, the inclination angle is 30 degrees. Multiple first drainage holes 4 are evenly spaced on the bottom wall of the planting box 3, and a first filter plate 5 is fixedly connected inside the first drainage hole 4. By setting the first filter plate 5, the seepage of water in the planting box 3 is reduced. The amount of soil loss 6 is reduced. The first drainage hole 4 is set in only one row. The first drainage hole 4 is located at least three-quarters of the length of the slope of the bottom wall of the planting box 3 from the lowest point to the highest point. The lower end of the installation box 2 is fixedly connected to the drainage box 7. The highest point of the slope of the bottom wall of the installation box 2 is provided with the second drainage hole 8. The rainwater in the installation box 2 is discharged into the drainage box 7 through the second drainage hole 8. The drainage box 7 is provided with the drainage outlet 9, which is connected to the drainage pipe 10 embedded in the concrete grid 1. At least one first drainage hole 4 is inserted with cotton strips 11. The first drainage hole 4 with cotton strips 11 inserted does not have a first filter plate 5. By setting the first drainage hole 4 on the bottom wall of the planting box 3, rainwater entering the planting box 3 is drained into the installation box 2 through the first drainage hole 4 on the bottom wall. The first drainage hole 4 is set at least three-quarters of the length from the lowest point to the highest point of the slope of the bottom wall inside the planting box 3, which reduces the amount of rainwater remaining in the planting box 3 and allows most of the rainwater to be drained out of the planting box 3 in time, reducing the probability of root rot of the plants. The rainwater drained into the planting box 3 reaches the second drainage hole 8 and then flows into the drainage box 7 through the drainage outlet 9 on the drainage box 7 into the drainage pipe 10. Finally, it flows into the water channel at the lowest point of the slope through the drainage pipe 10 (the water channel is not shown in the figure. Setting up the water channel is a conventional technical means in the prior art and will not be described in detail here). The planting box 3 can retain some rainwater, which is retained outside the planting box 3. By setting up the cotton strip 11, water is provided to the plants.

[0030] like Figure 1-6As shown, the opening size of the first water passage 4 is smaller than the opening size of the second water passage 8. The first water passage 4 is located at least three-quarters of the length of the sloped bottom wall of the planting box 3 from the lowest point to the highest point. In this embodiment, the first water passage 4 is located at three-quarters of the length of the sloped bottom wall of the planting box 3 from the lowest point to the highest point. The tilt angles of both the installation box 2 and the planting box 3 are 30 degrees. When the rainwater level in the installation box 2 just reaches the second water passage 8, the water level in the installation box 2 is exactly located at the first water passage 4 of the planting box 3. Since the opening size of the second water passage 8 is larger than the opening size of the first water passage 4, the combination of these two points can reduce the probability of rainwater in the installation box 2 flowing back into the planting box 3 through the first water passage 4, further reducing the probability of root rot in the plants.

[0031] like Figure 1-6 As shown, multiple limiting rings 12 are fixedly connected to the bottom wall and lower end face of the planting box 3. Cotton strips 11 are inserted into the limiting rings 12. One end of the cotton strip 11 inside the installation box 2 is fixedly connected to a counterweight 13. The free end of the cotton strip 11 inside the planting box 3 is inserted into a limiting rod 14. Before installing the planting box 3 into the installation box 2, the end of the cotton strip 11 away from the counterweight 13 is first passed through the limiting ring 12 at the bottom of the planting box 3, then through the first water passage 4, and finally through the limiting ring 12 inside the planting box 3. The limiting rod 14 is then inserted into the end of the cotton strip 11. Finally, planting soil 6 is covered inside the planting box 3. By setting a limiting ring 12, the cotton strip 11 is unfolded, which improves the efficiency of the cotton strip 11 in guiding water and wetting the planting soil 6. By setting a counterweight 13, the counterweight 13 slides to the bottom under gravity. When there is less rainwater in the installation box 2, the cotton strip 11 can also come into contact with the water located below the inclined surface inside the installation box 2. The counterweight 13 can also make the cotton strip 11 extend, reducing the probability of the cotton strip 11 piling up when covering the planting soil 6.

[0032] like Figure 1-6 As shown, a second filter plate 15 is fixedly connected inside the second water passage 8. The installation of the second filter plate 15 reduces the amount of debris entering the drainage tank 7.

[0033] like Figure 1-6 As shown, a rubber ring 16 is fixedly connected to one end of the drainage pipe 10 near the drain outlet 9. The inner diameter of the rubber ring 16 is the same as the inner diameter of the drain outlet 9. The peripheral sidewall of the rubber ring 16 just covers the drain outlet 9. After the installation box 2 is inserted into the concrete grid 1, the rubber ring 16 is just compressed. Due to its ability to recover its deformation, the rubber ring 16 abuts against the drainage box 7, reducing the probability of water leakage at the connection between the drain outlet 9 and the drainage pipe 10.

[0034] like Figure 1-6As shown, before pouring the concrete grid 1, the drainage pipe 10 is pre-installed in the formwork of the concrete grid 1. When setting up the formwork, the insertion ports for the installation box 2, planting box 3 and drainage box 7 are reserved. The connection between the drainage pipe 10 and the drainage outlet 9 is pre-marked according to the design dimensions.

[0035] The working principle of the geotechnical engineering slope seepage prevention and drainage structure in this embodiment is as follows: After installation, by setting the first water passage 4 at least three-quarters of the length from the lowest point to the highest point of the slope of the bottom wall inside the planting box 3, the amount of rainwater retained in the planting box 3 is reduced, allowing most of the rainwater to be discharged from the planting box 3 in a timely manner, reducing the probability of root rot in the plants. The rainwater discharged into the planting box 3 reaches the second water passage 8, and then flows into the drainage box 7 through the drainage outlet 9 on the drainage box 7, and finally into the drainage pipe 10, and finally into the water channel at the lowest point of the slope through the drainage pipe 10. The water in the planting box 3 can... Some rainwater is retained outside the planting box 3. By setting up cotton strips 11, water is provided to the plants. When the water level in the installation box 2 just reaches the second drainage hole 8, the water level in the installation box 2 is just at the first drainage hole 4 of the planting box 3. Since the opening size of the second drainage hole 8 is larger than the opening size of the first drainage hole 4, the combination of these two points can reduce the probability of rainwater in the installation box 2 flowing back into the planting box 3 through the first drainage hole 4, further reducing the probability of root rot in the plants. The concrete grid 1 and the planting box 3 work together to reduce the erosion of the slope surface by rainwater generated in the rainy environment and reduce the probability of water seepage on the slope.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
