Description

Municipal afforestation view system of circulation water conservation

Technical Field

The invention relates to the field of municipal greening engineering, in particular to a municipal greening landscape system capable of circularly saving water.

Background

With the development of economy in China, vehicles on roads are continuously increased, and the demand on municipal roads is continuously increased. The construction of municipal roads not only relates to the road surface construction, but also considers the arrangement of various pipelines such as electric power, communication, drainage and the like, and places higher requirements on cities with higher environmental requirements and greening of two sides of the roads. The side of town road is provided with the kerbstone, and the kerbstone is the inboard towards one side of road, is the outside towards outside greenbelt one side, and traditional town road construction, inlet for stom water set up the inboard at road kerbstone, and the inlet for stom water top sets up the rainwater grate, and the rainwater grate is made for materials such as concrete, cast iron, and the downspout lower extreme is connected and is used for the downspout of drainage. In order to prevent surface gathered water, the rainwater on municipal road surface directly gets into the downspout through the inlet for stom water after collecting and discharges, and on the other hand, the greenbelt of road both sides needs to be irrigated, needs additional municipal water supply to satisfy the irrigation demand again, and the rainwater on road surface can't directly be utilized, not only causes the water waste, but also has increased the human cost that the afforestation was maintained. Some researchers have proposed the concept of sponge city to collect rainwater on road surface and irrigate the road surface.

The "sponge city" means a city which has good elasticity in adaptation to environmental changes, coping with natural disasters, and the like, like a sponge, absorbs, stores, permeates and purifies water in the rainy season, and "releases" and utilizes the stored water when necessary. When collecting the rainwater and utilizing, prior art need excavate a sump pit specially as the rainwater cistern, or utilize finished product catch bucket to collect the rainwater after and carry out the rainwater and utilize again, this not only increases the rainwater and collects the cost of purifying, still occupies a large amount of lands, causes the land wasting of resources, and the result of use is relatively poor.
