Description

Technical Field

[0001] The present application relates to the field of ecological slope protection, and in particular to an ecological slope protection for a river embankment. Background Art

[0002] Ecological slope protection is a slope protection technology that integrates the basic knowledge of engineering mechanics, soil science, ecology and botany to support slopes or slopes, forming a comprehensive slope protection system composed of plants or engineering and plants. After the excavation slope is formed, by planting plants and utilizing the interaction between plants and rocks and soil (root anchoring effect) to protect and reinforce the surface of the slope, it can not only meet the requirements for the stability of the slope surface, but also restore the damaged natural ecological environment. It is an effective means of slope protection and consolidation.

[0003] In the related technology, a Chinese patent with announcement number CN204982784U discloses an ecological slope protection structure for a river embankment, including a back slope protection, a first slope protection, and a second slope protection. A embankment road is provided on the top of the slope, and a fitness trail is provided between the first slope protection and the second slope protection. The fitness trail is located above the normal water level. A mortar-laid stone foot trough is provided at the bottom of the second slope protection, and a riprap foot protection is provided on the side of the mortar-laid stone foot trough close to the river channel, and aquatic plants are planted in the river channel.

[0004] When encountering heavy rain, the soil and plants on the slope protection are soaked by rainwater and cannot be drained, making the soil loose and the plants damaged, so there is room for improvement. Utility Model Content

[0005] In order to improve the problem that excess water on the slope protection cannot be discharged, resulting in loose soil and damage to plants, the present application provides an ecological slope protection for a river embankment.

[0006] The present application provides a river embankment ecological slope protection adopting the following technical solution:

[0007] A river embankment ecological slope protection comprises a slope located on the side of the river channel, wherein one end of the slope away from the river channel is inclined upward, a plurality of planting troughs are arranged on the slope, a drainage pipe is arranged in the slope, the drainage pipe is arranged along the inclination direction of the slope, the planting troughs are connected with a connecting pipe, the drainage pipe is passed through the connecting pipe, a plurality of seepage holes are opened on the connecting pipe, the seepage holes are provided with a filter net, the connecting holes are connected with the drainage pipe, and the bottom end of the drainage pipe is connected with the river channel.

[0008] By adopting the above technical scheme, when encountering heavy rain weather, the rainwater falling on the slope is deposited in the planting trough and enters the connecting pipe, and the filter net in the seepage hole prevents the soil from passing through the pores of the filter net, thereby blocking the soil in the connecting pipe, which not only prevents soil loss, but also prevents the soil from entering the drain pipe and causing blockage of the drain pipe. However, the water in the soil will pass through the gaps in the filter net and enter the drain pipe. Since the drain pipe is set at an angle, the water entering the drain pipe will flow along the drain pipe from the bottom of the drain pipe to the river channel until the water deposited in the planting trough is discharged, reducing the probability of rainwater soaking in the soil in the planting trough for a long time, causing the soil to loosen, thereby making it less likely that the plants will be damaged.

[0009] Optionally, a filter plate is provided at the bottom end of the drain pipe.

[0010] By adopting the above technical solution, when excessive water in the planting trough enters the drain pipe through the seepage holes on the connecting pipe and then flows along the drain pipe to the bottom end of the drain pipe, the filter plate plays a filtering role, and impurities in the drain pipe cannot pass through the pores on the filter plate, and the pores of the filter plate do not hinder the passage of water, making it difficult for impurities in the drain pipe to be discharged into the river through the bottom opening of the drain pipe, thereby making the water resources in the river less likely to be polluted.

[0011] Optionally, a mounting sleeve is sleeved on the filter plate, the inner wall of the mounting sleeve is fitted and fixed to the circumferential side wall of the filter plate, and the mounting sleeve is sleeved on the drain pipe and threadedly connected to the drain pipe.

[0012] By adopting the above technical solution, when too many impurities are accumulated at the bottom of the drain pipe, the installation sleeve is rotated so that the installation sleeve drives the filter plate to be removed from the drain pipe, thereby facilitating cleaning of the filter plate and the inside of the drain pipe.

[0013] Optionally, a water-absorbing sponge is provided in the planting trough.

[0014] By adopting the above technical solution, the water-absorbing sponge absorbs part of the water for storage, so that when there is no rain or irrigation for a long time, the soil is not easy to dry up, thereby improving the water retention of the soil.

[0015] Optionally, the top end of the drain pipe passes through the top of the slope.

[0016] By adopting the above technical solution, when irrigation is needed, water is directly introduced into the top of the drainage pipe, so that the water flows along the drainage pipe toward the river. When the water enters the connecting pipe, part of the water will pass through the pores of the filter screen in the seepage hole into the connecting pipe and be absorbed by the soil in the connecting pipe, so as to irrigate the roots and stems of the plants without irrigating a large area of ​​the entire slope, and the operation is convenient. On rainy days, rainwater falling on the top of the slope can also enter the drainage pipe for discharge, thereby improving drainage efficiency.

[0017] Optionally, a sealing plate for sealing the top opening of the drain pipe is provided at the top of the slope, and a plurality of filter holes are penetrated through the sealing plate.

[0018] By adopting the above technical solution, the sealing plate covers the top opening of the drain pipe, making it difficult for impurities to enter the drain pipe through the filter hole, protecting the drain pipe, and thus making it difficult for the drain pipe to be blocked. At the same time, the sealing plate plays a supporting role, making it difficult for pedestrians to step into the drain pipe when walking on the top of the slope.

[0019] Optionally, one side of the sealing plate is hinged to the top wall of the slope.

[0020] By adopting the above technical solution, when impurities enter the drain pipe through the filter holes on the sealing plate, one side of the sealing plate is rotated away from the drain pipe, so that the top of the drain pipe is opened, so that the top of the drain pipe can be cleaned regularly to prevent impurities from clogging the drain pipe.

[0021] Optionally, a receiving groove is provided on the top wall of the slope, the top wall of the drain pipe is connected to the receiving groove, the sealing plate is located inside the receiving groove, and one side of the sealing plate is hinged to the inner wall of the receiving groove.

[0022] By adopting the above technical solution, when the sealing plate covers the top opening of the drain pipe, the sealing plate is completely accommodated in the accommodating groove, so that there is no protrusion on the top of the slope, which makes it difficult for pedestrians to trip when walking on the slope, thereby increasing the safety of the slope.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. When encountering heavy rain weather, rainwater falling on the slope is deposited in the planting trough and enters the connecting pipe. The filter net in the seepage hole prevents the soil from passing through the pores of the filter net, thereby blocking the soil in the connecting pipe, which not only prevents soil loss, but also prevents the soil from entering the drainage pipe and causing blockage of the drainage pipe. However, the water in the soil will pass through the gaps in the filter net and enter the drainage pipe. Because the drainage pipe is set at an angle, the water entering the drainage pipe will flow along the drainage pipe from the bottom of the drainage pipe to the river channel until the water deposited in the planting trough is discharged, reducing the probability of rainwater soaking in the soil in the planting trough for a long time, resulting in loose soil, so that the plants are not easily damaged;

[0025] 2. When the excess water in the planting trough enters the drain pipe through the seepage holes on the connecting pipe and then flows to the bottom of the drain pipe, the filter plate plays a filtering role. The impurities in the drain pipe cannot pass through the pores on the filter plate, and the pores of the filter plate do not hinder the passage of water, making it difficult for the impurities in the drain pipe to be discharged into the river through the bottom opening of the drain pipe, thereby making the water resources in the river less likely to be polluted.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses a river dam ecological slope protection. Figure 1 and Figure 2 The river embankment ecological slope protection includes a slope 10, which is located on one side of the river, and the end of the slope 10 away from the river is inclined upward, wherein the top wall of the slope 10 is walkable. A plurality of planting troughs 11 for planting plants are provided on the inclined surface of the slope 10, and the plurality of planting troughs 11 are arranged in an array, and a water-absorbing sponge 60 is placed in each planting trough 11, and the water-absorbing sponge 60 can absorb water, and can absorb part of the water for storage on rainy days, so that the soil is not easy to dry up when it is not raining or not irrigated, thereby improving the water retention of the soil.

[0034] Reference Figure 2 and Figure 3Each planting hole is connected to a connecting pipe 20, which is inserted into the slope 10. A plurality of seepage holes 21 are opened on the side wall of the connecting pipe 20. A filter screen 22 is provided in the seepage hole 21, and the circumferential side wall of the filter screen 22 is fixed to the inner wall of the seepage hole 21. A drainage pipe 30 is inserted into the slope 10, and the drainage pipe 30 is arranged along the inclination direction of the slope 10. The top end of the drainage pipe 30 passes through the top of the slope 10, and the bottom end passes through the slope 10 and is connected to the river. The connecting pipe 20 passes through the drainage pipe 30 along the width direction of the drainage pipe 30, and the seepage holes 21 are located in the drainage pipe 30.

[0035] When encountering heavy rain, rainwater falling on the inclined surface of the slope 10 tends to accumulate in the planting trough 11 and enter the connecting pipe 20, while the filter net 22 in the seepage hole 21 prevents the soil from passing through the pores of the filter net 22, thereby blocking the soil in the connecting pipe 20, which not only prevents soil loss, but also prevents the soil from entering the drain pipe 30 and causing blockage of the drain pipe 30. However, the water in the soil will pass through the gaps in the filter net 22 and enter the drain pipe 30. Since the drain pipe 30 is arranged at an angle, the water entering the drain pipe 30 is discharged from the bottom of the drain pipe 30 to the river channel along the drain pipe 30 until the water deposited in the planting trough 11 is discharged, thereby reducing the probability of rainwater soaking in the soil in the planting trough 11 for a long time, resulting in loose soil, thereby making it less likely that the plants will be damaged.

[0036] The rainwater falling on the top wall of the slope 10 will enter the drain pipe 30 through the top opening of the drain pipe 30, and then flow into the river channel from the bottom of the drain pipe 30 along the drain pipe 30, thereby improving the drainage efficiency of the slope 10 on rainy days.

[0037] Reference Figure 2 and Figure 4 In order to prevent impurities in the drain pipe 30 from being discharged into the river through the bottom opening of the drain pipe 30, a mounting sleeve 41 is provided on the upper sleeve of the drain pipe 30. The mounting sleeve 41 is located at the bottom end of the drain pipe 30 and is threadedly connected to the outer wall of the drain pipe 30. A filter plate 40 is inserted into the mounting sleeve 41, and the circumferential side wall of the filter plate 40 is integrally formed with the inner wall of the drain pipe 30.

[0038] When the excessive water in the planting trough 11 enters the drain pipe 30 through the seepage holes 21 on the connecting pipe 20 and then flows along the drain pipe 30 to the bottom of the drain pipe 30, the filter plate 40 plays a filtering role, and the impurities in the drain pipe 30 cannot pass through the pores on the filter plate 40, and the pores of the filter plate 40 do not hinder the passage of water, so that the impurities in the drain pipe 30 are not easy to be discharged into the river through the bottom opening of the drain pipe 30, so that the water resources in the river are not easy to be polluted. When too many impurities are accumulated at the bottom of the drain pipe 30, the installation sleeve 41 is rotated so that the installation sleeve 41 drives the filter plate 40 to be removed from the drain pipe 30, so as to facilitate the cleaning of the filter plate 40 and the inside of the drain pipe 30.

[0039] Reference Figure 2 and Figure 5 In order to prevent impurities from entering the drain pipe 30 through the top opening of the drain pipe 30 and causing the drain pipe 30 to be blocked, a receiving groove 12 is first opened on the top wall of the slope 10, and the top end of the drain pipe 30 is connected to the receiving groove 12, and then a sealing plate 50 is placed in the receiving groove 12. The sealing plate 50 can completely cover the top opening of the drain pipe 30. One side of the sealing plate 50 is hinged to the inner wall of the receiving groove 12 through a rotating shaft. A plurality of filter holes 51 are opened through the sealing plate 50, and the filter holes 51 are connected to the drain pipe 30.

[0040] When the sealing plate 50 covers the top opening of the drain pipe 30, the sealing plate 50 is completely contained in the containing groove 12, so that there is no protrusion on the top of the slope 10, so that pedestrians are not easily tripped when walking on the slope 10, which increases the safety of the slope 10. When it is necessary to pass water into the drain pipe 30 to irrigate plants, water can be directly poured into the containing groove 12. The containing groove 12 can act as a funnel to facilitate water to enter the drain pipe 30 through the filtering hole 51, that is, there is no need to align the top opening of the drain pipe 30 with the human eye to pour water into the drain pipe 30, which is more convenient to operate and can also reduce the possibility of spilling water around the drain pipe 30 due to misalignment with the drain pipe 30, thereby reducing the waste of water resources.

[0041] The filter holes 51 on the sealing plate 50 limit the passage of impurities and play a role of limiting protection, but water can directly enter the drain pipe 30 through the filter holes 51. If impurities with smaller diameters still enter the water inlet pipe through the filter holes 51, one side of the sealing plate 50 is moved away from the drain pipe 30, that is, the sealing plate 50 rotates around the connection between the sealing plate 50 and the inner wall of the receiving groove 12, so that the top of the drain pipe 30 is opened, which is convenient for regular cleaning of the top of the drain pipe 30 to prevent impurities from clogging the drain pipe 30.

[0042] The implementation principle of an ecological slope protection for a river embankment in an embodiment of the present application is as follows: when encountering heavy rain, rainwater falling on the slope 10 is deposited in the planting trough 11 and enters the connecting pipe 20, and the filter net 22 in the seepage hole 21 prevents the soil from passing through the pores of the filter net 22, thereby blocking the soil in the connecting pipe 20, which prevents soil loss and prevents the soil from entering the drain pipe 30 and causing blockage of the drain pipe 30. However, the water in the soil will pass through the gaps in the filter net 22 and enter the drain pipe 30. Since the drain pipe 30 is arranged at an angle, the water entering the drain pipe 30 is discharged from the bottom of the drain pipe 30 along the drain pipe 30 to the river channel until the water deposited in the planting trough 11 is discharged, thereby reducing the probability of rainwater soaking in the soil in the planting trough 11 for a long time, resulting in loose soil, thereby making it difficult for plants to be damaged.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
