Technical Field
[0001] The utility model relates to the technical fields of sponge city and soil and water conservation, and particularly relates to an adjustable ecological grassed swale seepage system. Background Technique
[0002] At present, the ecological grassed swale is a common sponge city measure. As Figure 2 shown in the structural schematic diagram of a road, ecological grassed swales 14 are distributed on both sides of the carriageway 15. A permeable pipe 8 is buried at the bottom of the ecological grassed swale 14, and one end of the permeable pipe 8 is directly communicated with an inspection well 13. When it rains, part of the rainwater permeating through the soil enters the permeable pipe 8 and is directly and quickly discharged to the inspection well 13 by the permeable pipe 8.
[0003] From the above structure of the existing ecological grassed swale 14, it can be seen that it does not have the rainwater storage capacity. The rainwater will be directly discharged to the inspection well 13 by the permeable pipe 8, and it cannot store rainwater usually to provide moisture for the soil, and it cannot play a buffering and regulating role when encountering heavy rain. Content of the Utility Model
[0004] The purpose of the utility model is to provide an adjustable ecological grassed swale seepage system, which can timely adjust the water storage volume of the ecological grassed swale according to the local climate characteristics, store rainwater for a long time in the dry season, continuously provide moisture for the soil, and play a buffering and regulating role when the rainfall is large.
[0005] The purpose of the utility model is realized by the following technical solutions:
[0006] An adjustable ecological grassed swale seepage system, characterized in that: it includes a permeable pipe buried at the bottom of the ecological grassed swale and anti-seepage membranes arranged on the two side surfaces and the bottom surface of the ecological grassed swale. A plurality of water permeable holes are provided on the permeable pipe. One end of the permeable pipe is connected with an observation pipe, and the upper end of the observation pipe extends above the ecological grassed swale. The other end of the permeable pipe extends out to an inspection well or an overflow well, and a vertically upward overflow pipe is arranged at the end of the permeable pipe extending out to the inspection well or the overflow well.
[0007] Further, a gravel water storage layer, a planting soil layer and a gravel drainage layer are sequentially arranged from top to bottom in the ecological grassed swale, and the permeable pipe is horizontally arranged at the bottom of the gravel drainage layer.
[0008] Further, an anti-filtration geotextile is provided between the planting soil layer and the gravel drainage layer.
[0009] Further, the overflow pipe is a telescopic pipe that can be adjusted up and down.
[0010] Further, it further includes a tee joint. The first port of the tee joint is connected to the end of the water permeable pipe extending into the inspection well or the overflow well. The second port of the tee joint faces vertically upward, and the overflow pipe is connected to the second port of the tee joint. The third port of the tee joint is sealed by a cover.
[0011] Further, the observation pipe is inclined.
[0012] Further, an end cover is provided at the upper end of the observation pipe.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] With the utility model, rainwater can be stored in the ecological grass planting ditch through the anti-seepage membrane to provide moisture for the soil and plants. At the same time, the overflow pipe connected to the water permeable pipe is used to adjust the water storage capacity. When the water storage capacity exceeds the upper end of the water permeable pipe, the water in the ecological grass planting ditch can be discharged from the overflow pipe to the inspection well or the overflow well, realizing the regulation of rainwater in the ecological grass planting ditch. When the rainfall is large, through the regulation ability of the ecological grass planting ditch, buffering and regulation can be formed to avoid a large amount of rainwater pouring into the inspection well or the overflow well at once, causing waterlogging.

[0024] Embodiment:
[0025] As Figure 1 Shown is an adjustable storage ecological grass-planting ditch seepage system according to this embodiment, which includes a permeable pipe 8 buried at the bottom of the ecological grass-planting ditch and anti-seepage membranes 4 provided on both side surfaces and the bottom surface of the ecological grass-planting ditch.
[0026] The anti-seepage membrane 4 can prevent the water in the ecological grass-planting ditch from seeping to both sides and the ground, so that the water can be stored in the ecological grass-planting ditch, thereby providing water for the soil and plants.
[0027] The ecological grass-planting ditch is successively provided with a gravel water storage layer 1, a planting soil layer 2 and a gravel drainage layer 3 from top to bottom. The permeable pipe 8 is horizontally arranged at the bottom of the gravel drainage layer 3. The thickness of the gravel water storage layer 1 in this embodiment is 20 cm, the thickness of the gravel drainage layer 3 is 30 cm, and the specification of the permeable pipe 8 is DN160.
[0028] There is an anti-filter geotextile 5 between the planting soil layer 2 and the gravel drainage layer 3. The anti-filter geotextile 5 can allow water to pass through while blocking the soil and sand of the planting soil layer 2 on it, so that the water can penetrate to the gravel drainage layer 3 and prevent the soil and sand of the planting soil layer 2 from entering the gravel drainage layer 3.
[0029] Among them, a number of water permeable holes 9 are provided on the water permeable pipe 8, and water can enter the water permeable pipe 8 through the water permeable holes 9. One end of the water permeable pipe 8 is connected to an observation pipe 6, the observation pipe 6 is inclined, the upper end of the observation pipe 6 extends above the ecological grass planting ditch, and an end cover 7 is provided at the upper end of the observation pipe 6. The upper port of the observation pipe 6 can be used as an observation port or a cleaning port. During use, the internal water level and other conditions can be observed through the upper port of the observation pipe 6, and the inside can also be cleaned through the observation pipe 6, which is convenient for maintenance.
[0030] The other end of the water permeable pipe 8 extends out to the inspection well 13 or the overflow well. This embodiment also provides a tee joint 10. The first port of the tee joint 10 is connected to the end of the water permeable pipe 8 extending out to the inspection well 13 or the overflow well. The second port of the tee joint 10 is vertically upward, and an overflow pipe 11 is connected to the second port of the tee joint 10. The third port of the tee joint 10 is sealed by a cover. During maintenance, the cover can be unscrewed to dredge and clean the water permeable pipe 8, making the maintenance more convenient.
[0031] The overflow pipe 11 is vertically upward. The overflow pipe 11 can prevent the water in the water permeable pipe 8 from directly draining into the inspection well 13 or the overflow well. Only when the water storage capacity of the ecological grass planting ditch exceeds the upper end of the overflow pipe 11, the water in the ecological grass planting ditch can drain from the overflow pipe 11 into the inspection well 13 or the overflow well, so that the ecological grass planting ditch can store water and can adjust the water storage capacity.
[0032] The overflow pipe 11 of this embodiment adopts a telescopic pipe that can be adjusted up and down. By adjusting the height telescopically, the water storage capacity in the ecological grass planting ditch can be adjusted, so as to better adapt to different situations. The overflow pipe 11 adopts a conventional telescopic structure. For example, as shown in the figure, the overflow pipe 11 is divided into multiple sections of sleeves, and the multiple sections of sleeves are sleeved together in sequence. The sleeves are limited by buckles between the sleeves, or can also be locked and limited by bolts.
[0033] During the use of this embodiment, rainwater can penetrate through the gravel water storage layer 1 and the planting soil layer 2 and seep into the gravel drainage layer 3. When there is little rain, the rainwater will be stored in the ecological grass planting ditch. When there is more rain and it rises above the upper end of the overflow pipe 11, the excess part will drain from the overflow pipe 11 into the inspection well 13 or the overflow well. The bottom of the inspection well 13 or the overflow well is connected to a DN300 horizontal water pipe 12, and the horizontal drainage pipe 12 is connected to the municipal rain inspection well for draining rainwater.
[0034] The above embodiments of the present utility model do not limit the protection scope of the present utility model. The implementation manners of the present utility model are not limited thereto. All such modifications, substitutions or alterations in various other forms made to the above structure of the present utility model according to the above content of the present utility model, in accordance with the common general technical knowledge and customary means in the art, without departing from the above basic technical idea of the present utility model, shall fall within the protection scope of the present utility model.
