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...

Abstract

The invention provides a collection, storage, and drain integrated rainfall flood holding up culvert which includes a holding up buried culvert and ecological forest. The holding up buried culvert is buried underground. The ecological forest is composed an above ground part and an underground part. The holding up buried culvert is connected to the underground part of the ecological forest. The holding up buried culvert is provided with a plurality of drain holes thereon. The invention also provides a rainwater recycling method. According to the invention, the holding up buried culvert saves land occupation and has small influence on ambient environment. The holding up buried culvert is in a penetration encircling arrangement, so that with respect to point arrangement, the holding up buried culvert has explicit advantages at addressing the problems of large area rainwater recycling by mitigating water resource shortage, alleviating flood prevention burden of downstream cities, and reducing non point source pollution, and the holding up buried culvert has scenic value.

Description

technical field [0001] The invention belongs to the technical field of urban rainwater management, and in particular relates to a rainwater interception culvert integrated with collection, storage and drainage and a rainwater resource utilization method. Background technique [0002] my country is a country seriously short of water resources, and the per capita water resources are less than 2200m 3 , and the distribution of water resources is uneven, with more in the south and less in the north. In recent years, urban water shortage has not only seriously affected economic development and people's production and life, but also caused a series of ecological problems due to the excessive development and utilization of water resources. While water resources are in short supply, severe water pollution has not yet been effectively controlled. In particular, the control of rainwater runoff pollution is difficult and has a high impact on the surface water environment, which has be...
