[0034] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The following combination Figures 1 to 3 The drainage ditch provided by the utility model is suitable for drainage and greening work at the foot of the slope 10 of production and construction projects, and is used for soil and water conservation and landscaping.

[0036] like Figures 1 to 3 As shown, the drainage ditch provided by the embodiment of the present invention includes a first ditch body, a first cover plate, a second ditch body and a partition penetration plate 2.

[0037] Specifically, the first ditch body is arranged at the foot of the slope 10, and the first ditch body has a drainage space 1 for drainage.

[0038] The first cover plate is fixedly arranged above the first ditch body, and the second ditch body is arranged above the first cover plate. A water inlet channel is formed on one side of the second ditch body close to the slope 10 to allow drainage from the slope 10 to enter the second ditch body.

[0039] A partitioning permeable plate 2 is installed within the second trench, dividing the space within the second trench into a planting space 3 and a water storage space 4. The planting space 3 is filled with soil for growing plants. The planting space 3 is located above the drainage space 1, overlapping the drainage space 1 to conserve land.

[0040] The portion of the first cover plate corresponding to the planting space 3 is the first cover plate portion 6, and the portion of the first cover plate corresponding to the water storage space 4 is the second cover plate portion 7. The first cover plate portion 6 and the second cover plate portion 7 can be set separately or as an integrated structure, and there is no specific limitation.

[0041] The first cover portion 6 is provided with a first drainage hole 8, which is connected to the drainage space 1. When there is too much water in the planting space 3, after the water in the planting space 3 fully soaks the soil in the planting space 3, the excess water will be discharged to the drainage space 1 through the first drainage hole 8, thereby being discharged.

[0042] The partition infiltration plate 2 is provided with seepage holes, which connect the planting space 3 and the water storage space 4. When the planting space 3 lacks water, the water in the water storage space 4 can seep into the planting space 3, supplying water to the planting space 3 and ensuring plant growth.

[0043] In this way, a water storage space 4 and a planting space 3 are set above the drainage space 1, and the drainage of the slope 10 first enters the planting space 3 and the water storage space 4 through the water inlet channel. The drainage of the slope 10 enters the planting space 3, and the water therein provides moisture for the plants. After the water in the planting space 3 fully infiltrates the soil in the planting space 3, the excess water will be discharged to the drainage space 1 through the first drainage hole 8. The sediment in the drainage of the slope 10 is deposited in the planting space 3, which prevents the sediment in the drainage of the slope 10 from entering the drainage space 1, and prevents the drainage space 1 from being blocked. When the planting space 3 is short of water, the water in the water storage space 4 will automatically penetrate into the planting space 3 under the action of osmotic pressure, and supply water to the planting space 3, realizing the utilization of the drainage of the slope 10, thereby solving the problems of soil erosion and easy blockage in the drainage ditch in the related art.

[0044] There are multiple seepage holes, which are spaced and evenly distributed on the partition permeation plate 2 .

[0045] A plurality of first drainage holes 8 are provided, and the plurality of first drainage holes 8 are distributed at intervals and evenly on the first cover portion 6 .

[0046] In the embodiment of the present invention, the second trench body includes a third side wall 9 and a pair of end walls 11 , and the third side wall 9 and the pair of end walls 11 are both fixedly disposed above the first cover plate.

[0047] A gap exists between the third sidewall 9 and the slope surface of the side slope 10. Along the extension direction of the first trench, two of a pair of end walls 11 are disposed at either end of the third sidewall 9. A partitioning permeable plate 2 is disposed between the pair of end walls 11. The space between the pair of end walls 11, the third sidewall 9, and the slope surface of the side slope 10 is divided by the partitioning permeable plate 2. The space on one side of the partitioning permeable plate 2 serves as a planting space 3, while the space on the other side of the partitioning permeable plate 2 serves as a water storage space 4.

[0048] In this embodiment, at least two partitioning permeable plates 2 are provided, spaced apart along the extension direction of the first trench. Along the extension direction of the first trench, a water storage space 4 is provided on either side of the planting space 3. Both water storage spaces 4 on either side of the planting space 3 can supply water to the planting space 3.

[0049] Reference Figure 1 Two partition infiltration plates 2 are provided in the second ditch body, the space between the two partition infiltration plates 2 is the planting space 3, and the space between the end wall 11 and the partition infiltration plate 2 is the water storage space 4.

[0050] Specifically, the third side wall 9, the first cover plate, the partitioning infiltration plate 2, and the side slope 10 enclose the planting space 3. The slope surface of the side slope 10 serves as the side wall of the planting space 3. There is no barrier between the planting space 3 and the slope surface of the side slope 10. The planting space 3 is completely connected to the space above the slope surface of the side slope 10, and can serve as part of the water inlet channel. Drainage from the side slope 10 can directly enter the planting space 3.

[0051] In this embodiment of the present invention, the second trench body further includes a fourth side wall 12, which is fixedly mounted above the first cover plate and located on the side of the third side wall 9 adjacent to the side slope 10. The fourth side wall 12, the end wall 11, the third side wall 9, the partitioning infiltration plate 2, and the first cover plate together form the water storage space 4. The third side wall 9 isolates the water storage space 4 from the side slope 10, thereby preventing water in the water storage space 4 from penetrating into the side slope 10.

[0052] The water inlet channel includes a first water inlet hole 14, which is provided at the upper end of the fourth side wall 12. Drainage from the slope 10 can enter the water storage space 4 through the first water inlet hole 14.

[0053] A plurality of first water inlet holes 14 are provided, and the plurality of first water inlet holes 14 are spaced and evenly distributed on the upper end of the fourth side wall 12 .

[0054] The fourth sidewall 12 is angled relative to the slope 10, forming a sand-retaining space 13 between the fourth sidewall 12 and the slope 10. Drainage from the slope 10 first passes through the sand-retaining space 13, where sediment in the water settles and remains. Water then enters the water storage space 4 through the first water inlet 14, thereby reducing sediment in the water storage space 4.

[0055] It should be noted that plants can also be planted in the sand-trapping space 13. The planting space 3 and the sand-trapping space 13 need to be filled with soil, and artificial plants such as trees, shrubs, and vines can be planted in the soil. The soil level in the planting space 3 should be lower than the height of the upper end surface of the third side wall 9, and the soil level in the sand-trapping space 13 should be lower than the height of the upper end surface of the fourth side wall 12.

[0056] In the embodiment of the present invention, a second drain hole 15 is provided at the portion of the third side wall 9 corresponding to the water storage space 4. The second drain hole 15 is located at the upper end of the third side wall 9. When there is too much water in the water storage space 4, it will be discharged through the second drain hole 15.

[0057] In a further embodiment, the first trench body includes a first side wall 16 and a second side wall 17, wherein the second side wall 17 is located on the side of the first side wall 16 close to the slope 10. The surface of the third side wall 9 is located between the surfaces of the first side wall 16 and the second side wall 17, that is, the first cover plate is not completely covered by the second trench body.

[0058] The height of the upper end of the first side wall 16 is greater than the height of the first cover plate. A through groove structure is formed between the first side wall 16, the third side wall 9 and the first cover plate. After the water in the water storage space 4 is discharged through the second drainage hole 15, it will enter the through groove structure. The first side wall 16 can prevent the water discharged from the water storage space 4 from flowing to the outside of the drainage ditch.

[0059] A second water inlet hole 18 is provided on the first cover plate, located between the first side wall 16 and the third side wall 9. The second water inlet hole 18 passes through the first cover plate to communicate with the drainage space 1. Water discharged from the water storage space 4 can enter the drainage space 1 and be discharged along with the water in the drainage space 1.

[0060] A plurality of second water inlet holes 18 are provided, and along the extension direction of the first groove body, the plurality of second water inlet holes 18 are distributed on the first cover plate at intervals.

[0061] When there is too much water in the planting space 3 and there is no time for the water to penetrate into the first drainage hole 8, the water in the planting space 3 can also pass over the third side wall 9, be discharged from the upper end of the third side wall 9, and be discharged into the drainage space 1 through the above-mentioned groove structure and the second water inlet hole 18.

[0062] In the embodiment of the present invention, the drainage ditch further includes a filter element 19, which is disposed in the planting space 3 and is located at the bottom of the planting space 3. Water in the planting space 3 passes through the filter element 19 and is then discharged through the first drainage hole 8. The filter element 19 can filter the drainage of the planting space 3 to prevent soil, sediment, etc. in the planting space 3 from entering the drainage space 1.

[0063] In this embodiment, the separation permeation plate 2 may be, but is not limited to, a microporous plate.

[0064] In the embodiment of the present invention, the drainage ditch further includes a second cover plate 5, which is fixedly arranged above the second ditch body and is used to cover the water storage space 4. Covering the water storage space 4 with the second cover plate 5 can reduce the evaporation loss of water in the water storage space 4.

[0065] In summary, the drainage ditch provided by the present embodiment combines drainage, sand retention, water storage, and space conservation, effectively reducing soil erosion and preventing clogging of drainage space 1. Furthermore, its water storage function reduces the need for artificial watering of plants in areas with low natural rainfall. Furthermore, the planting space 3 can be used for planting, increasing greenery and being more suitable for projects with limited landscaping and limited available green space.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
