In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0031] like Figure 1-3 As shown, the embodiment of the utility model is a butterfly-shaped drainage ditch for a sponge city greenway, comprising a ditch body 1 and a water storage part 2. A permeable cover plate 5 is provided on the top of the ditch body 1. The permeable cover plate 5 can prevent foreign objects from entering the drainage ditch and blocking the drainage ditch. The water storage part 2 is arranged on the upper outer part of the ditch body 1. When the water in the ditch body 1 reaches the overflow position, the water can overflow to the water storage part 2 and penetrate into the soil through the water storage part 2 to avoid the overflow of water and cause water accumulation inside the city. The water storage part 2 of the ditch body 1 is integrally arranged with the ditch body 1. The water storage part 2 is two separate water storage cavities, which are symmetrically arranged on both sides of the ditch body 1 along the flow direction of the water body to play an overflow role. The water storage part 2 includes a vertical part 4 and a horizontal part 3 connected in an integral manner. The top of the vertical part 4 is integrally connected with the ditch body 1, and the side of the horizontal part 3 away from the vertical part 4 is connected to the ditch body 1. The connection between the vertical part 4 and the horizontal part 3 is arc-shaped. The groove body 1 is usually set to have a lateral width of 60-70 cm, a longitudinal length along the water flow of 40-50 cm, a height of 50-60 cm, and a wall thickness of 6-8 cm. The water storage part 2 is usually set to have a horizontal part 3 of 5-6 cm and a vertical part 4 of 8-10 cm.

[0032] Specifically, the water-permeable cover plate 5 is evenly distributed with water-permeable holes 6. The shape of the water-permeable holes 6 is not limited, and can be circular, square or rectangular. The inner wall of the water-permeable hole 6 can be a straight wall or an inclined wall.

[0033] Specifically, a water pipe 7 is provided at the lower part of one side of the water storage part 2 close to the groove main body 1, which is used to overflow the water in the groove main body 1 to the water storage part 2. There is no limit on the number of water pipes 7, and usually a plurality of water pipes are provided, which are arranged at equal intervals along the flow direction of the water body. One end of the water pipe 7 extends into the water storage part 2, and a certain distance is left from the bottom of the water storage part 2, i.e., the horizontal part 3. The size of the distance is not limited to avoid backflow of water. The other end of the water pipe 7 extends into the interior of the groove main body 1 and is set downward, and the end is tangent to the side wall of the groove main body 1. There is no limit on the cross-sectional shape of the water pipe 7, which can be circular, quadrilateral, or arc-shaped at the top and horizontal at the bottom.

[0034] A water outlet channel 8 is provided on the upper part of one side of the water storage part 2 close to the groove body 1. When there is too much water in the water storage part 2, the pressure of the water body when penetrating into the soil body is too large, which will scour the soil body and cause soil and water loss. Therefore, when the water level of the water storage part 2 reaches the position of the water outlet channel 8, the water body will flow from the water storage part 2 to the groove body 1, so that the water level of the water storage part 2 will not exceed the height of the water outlet channel 8, and the pressure of the water body when penetrating into the soil body will not be too large. The number of water outlet channels 8 is not set, and usually multiple water outlet channels are set, which are arranged at equal intervals along the flow direction of the water body. The cross-sectional shape of the water outlet channel 8 is not limited, and can be circular, quadrilateral or other shapes.

[0035] A water seepage channel 9 is provided on one side of the water storage part 2 away from the groove body 1, which is used to infiltrate the water in the water storage part 2 into the external soil. The number of water seepage channels 9 is not limited, and a plurality of water seepage channels 9 are usually provided, evenly distributed in the vertical part 4 of the water storage part 2. The cross-sectional shape of the water seepage channel 9 is not limited, and can be circular, quadrilateral or other shapes.

[0036] In order to prevent foreign matter from entering the water pipe 7, the water outlet channel 8 and the water seepage channel 9 and causing blockage, a filter body (not shown in the figure) can be filled in the water pipe 7, the water outlet channel 8 and the water seepage channel 9 to filter the foreign matter. The specific shape of the filter body is not limited, and it can be a polyester or polyether type slice body, which is bonded to the inside of the water pipe 7, the water outlet channel 8 and the water seepage channel 9.

[0037] In order to facilitate fixing, wing plates 10 are symmetrically arranged on both sides of the top of the groove body, and mounting holes 11 are arranged on the outer sides of the wing plates 10, and bolts are used to fix the groove body to the road surface. The number of mounting holes 11 is not limited, and a plurality of mounting holes 11 are usually provided, which are arranged at equal intervals along the flow direction of the water body. The thickness of the wing plates 10 is usually set to 6-8 cm.

[0038] The drainage ditch made of ordinary cement is gray in color, and a large number of paving can easily cause hardening of the land. Plant-type recycled concrete is a new type of environmentally friendly building material that combines concrete with plant growth, which can not only meet the structural requirements of the building, but also improve the ecological environment. Benefiting from its special concrete structure, it can not only withstand external loads, but also has a certain restraining effect on the soil to prevent soil erosion. In some embodiments, the drainage ditch is made of plant-type recycled concrete. The interior of the groove body 1 is provided with symmetrical main force reinforcement 13 along the longitudinal direction, that is, the flow direction of the water body, and secondary force reinforcement is provided along the transverse direction, which is not shown in the figure. The secondary force reinforcement extends to the wing plate 10 and is fixedly connected to the main force reinforcement 13, forming a mesh. Plant planting holes 12 are provided on the inner side of the wing plate 10, and the number is not limited. Usually, multiple holes are provided, which are evenly arranged at equal intervals along the flow direction of the water body. Plants planted in the plant planting holes 12 can be irrigated with water seeping from the water storage part 2, which realizes resource reuse and saves water resources. In order to facilitate the planting of plants and ensure that the water seeping from the water storage part 2 can enter the soil where the plants are planted, the width of the horizontal part 3 of the water storage part 2 is smaller than the width of the wing plate 10 .

[0039] like Figure 4-5 As shown, the drain channel is formed by connecting a plurality of butterfly drains. For the convenience of connection, a first groove 14 is provided on one side of the connecting end surface of the wing plate 10, and a first protrusion 15 is provided at a relative position of the other side of the connecting end surface, and the first groove 14 and the first protrusion 15 are adapted. The first groove 14 and the first protrusion 15 of two adjacent butterfly drains can be mutually engaged. A second groove 16 is provided on one side of the connecting end surface of the groove body 1, and a second protrusion 17 is provided at a relative position of the other side of the connecting end surface, and the second groove 16 and the second protrusion 17 are adapted. The second groove 16 and the second protrusion 17 of two adjacent butterfly drains can be mutually engaged. The shapes of the first groove 14 and the first protrusion 15 and the second groove 16 and the second protrusion 17 are not limited. The groove can be set as a mortise and tenon type open groove or a U-shaped open groove. When the adjacent grooves and protrusions are connected, an aging-resistant elastic colloid can be injected to facilitate the movement between the two adjacent drains, avoid the generation of abnormal cracks, and extend the life of the drain. The elastic colloid is a prior art and will not be described here.
