Embodiment 1
[0034] This embodiment provides an integrated rainwater interception culvert for collection, storage and drainage, including an interception culvert 7 and an ecological forest 3, the interception implicit culvert 7 is arranged under the ground, and the ecological forest 3 consists of an aboveground part and an ecological forest 3. The underground part is composed of the underground part of the intercepting culvert 7, which is connected with the underground part of the ecological forest 3, and a plurality of drainage holes 6 are arranged on the intercepting implicit culvert 7.
[0035] The intercepted culvert collects and stores rainwater, and the ecological forest 3 absorbs, stores and stagnates rainwater and seeps out, reducing runoff, reducing the city's flood control load and non-point source pollution. After the rainwater is collected, the collected rainwater needs to be released and reused, and the collected rainwater is discharged through the drainage hole 6 or the pipeli...
Embodiment 2
[0037] On the basis of embodiment 1, this embodiment provides a kind of figure 1 In the illustrated stormwater interception culvert integrated with collection, storage and drainage, the interception culvert 7 includes a lower water storage area 12 and an upper overflow area 13 .
[0038] The intercepting culvert 7 is an L-shaped intercepting culvert, the vertical section of the L-shaped intercepting culvert is the overflow area 13, the horizontal section is the water storage area 12, and the ecological forest 3 is above the horizontal section;
[0039] The top of the overflow area 13 is provided with a grid 5, and the overflow plate 4 is arranged at intervals in the water storage area 12, and the overflow plate 4 is parallel to the horizontal section of the L-shaped intercepting culvert, and the drainage hole 6 It is arranged at the bottom of the overflow plate 4, and each overflow plate 4 has a drainage hole 6 at the bottom.
[0040] The rainwater intercepting culvert of the...
Embodiment 3
[0044] On the basis of Embodiment 2, this embodiment provides a rainwater interception culvert integrating collection, storage and drainage, and the volume of the water storage area 12 is larger than that of the overflow area 13 . Make the water storage capacity greater than the overflow water volume, reduce runoff and recycle more rainwater.
[0045] Wherein, the L-shaped intercepting culvert is surrounded by concrete lining 11, the bottom is a precast concrete slab, the overflow plate 4 is a precast concrete slab, the bottom is connected with the precast concrete slab at the bottom of the L-shaped intercepting culvert, and the top is semicircular. The length of the overflow plate 4 is the same as the length of the horizontal section of the L-shaped intercepting culvert, and the height is the same as that of the water storage area 12 .
[0046] The L-shaped intercepting culvert shall be determined in combination with the project scale and regional land use conditions. The thi...
