Embodiment 1

[0037] A sunken greenbelt oriented siphon drainage infiltration system, arranged in the sunken greenbelt, such as Figure 1 to Figure 4 As shown, it includes a siphon water pipe 1, and also includes a sinking perforated water pipe 2, one end of the sunken type perforated water pipe 2 is connected to the siphon water pipe 1, and the other end is connected to the siphon air pipe 3; the siphon air pipe 3 sinks The perforated diffuser pipe 2 is connected to the atmosphere, so that the air pressure in the sunken perforated diffuser pipe 2 is the atmospheric pressure value, so that the sunken perforated diffuser pipe 2 produces a siphon effect when reaching the design water level. The siphon ventilation pipe should be at least 30cm above the ground.

[0038] Plant relatively tall plants (dianthus, funnel) around the sunken green space 16, and plant low-slung and hard-working plants (five-leaf cotton, snakeberry) in the center of the sunken green space, especially near the siphon wat...

Embodiment 2

[0051] This embodiment provides an anti-pollution diffusion measure for sunken green spaces near urban black and odorous water bodies. On the basis of Embodiment 1, this embodiment provides more specifically: the application position of this device system, this device system can be applied around the black and odorous water body in the city, when the rainfall is too large and exceeds the carrying capacity of the black and odorous water body, There will be black and smelly water overflow phenomenon. The device system can carry the overflowing black and smelly water by laying around the black and smelly water body, and pass it through the plants in the sunken green space and introduce it into the ground for digestion and treatment.

Embodiment 3

[0053] This embodiment provides a rainwater-guided infiltration structure used in loess areas. By setting the system of the present invention on the side of the sunken green space away from the building foundation structure, when the water volume of the sunken green space reaches the set position, the accumulated water can be quickly introduced into the side of the building structure foundation through the generated siphon effect. The perforated water pipe 4 realizes the directional drainage of the sunken green land in the collapsible loess area, and protects the building foundation on the side of the sunken green land in the collapsible loess area.

Abstract

The invention provides a siphon drainage and infiltration system for sunken green areas, which includes a siphon water pipe and a sunken perforated water pipe. Connection; the sunken perforated water pipe includes a perforated pipe and a variable diameter pipe connected at both ends of the perforated pipe. A number of through holes are arranged on the perforated pipe along the circumference. The diameter of the pipe or the siphon air pipe is the same; the perforated pipe and the siphon water pipe or the siphon air pipe are horizontally and non-axially arranged, and the top of the perforated pipe is kept at the same level as the top of the siphon water pipe and the siphon air pipe; the bottom of the system of the present invention The sunken perforated water pipe is connected with the siphon water pipe. The sunken design structure of the perforated water pipe can store the stagnant water that cannot be infiltrated quickly due to the limited infiltration of the soil, so that the siphon effect is always maintained at a high performance state.

Description

technical field [0001] The invention belongs to the technical field of rainwater seepage, and in particular relates to a sunken green space-guided siphon drainage infiltration system. Background technique [0002] The green spaces in ordinary green areas in Northwest China are mostly higher than or flat on the road surface, there is no water accumulation during rainfall, and the amount of soil infiltration and rainwater is small; while the new green spaces based on the concept of "sponge city" mostly use concave green spaces, and surface runoff sinks during rainfall. In most areas, the rainwater infiltrates into the sunken green area to recharge the groundwater to realize the return and utilization of rainwater, so that the city can accommodate more rainfall. In addition, due to the long time of water accumulation in the sunken green land, the water quality is poor and the methane production is high. It is one of the hardest hit areas of black and odorous water in the city. ...
