Gravity-flowing type rainwater collection and irrigation system of green belt under viaduct

Abstract

The invention discloses a gravity-flowing type rainwater collection and irrigation system of a green belt under a viaduct. The gravity-flowing type rainwater collection and irrigation system comprises a surface runoff collection device and a viaduct drainage collection device; the surface runoff collection device comprises transverse water collection grooves; the surfaces of the transverse water collection grooves are connected with a longitudinal communication groove in an inserting manner; water outlets are formed in the bottom of the longitudinal communication groove; the viaduct drainage collection device comprises a funnel; the bottom end of the funnel is fixedly connected with a water inlet pipe; and the longitudinal communication groove is fixedly connected with the top ends of first underground fluid conveying pipes through the water outlets. According to the gravity-flowing type rainwater collection and irrigation system, with arrangement of the surface runoff collection device and the viaduct drainage collection device, rainwater resources are effectively collected; with arrangement of the first underground fluid conveying pipes, a second underground fluid conveying pipe and an underground collecting pipe, a water source can be conveyed underwater, so that direct sunlight can be prevented, the underground temperature is lower than the land surface temperature, water evaporation is reduced, and water resources are effectively utilized; and with arrangement of an irrigation flume and a water drawing pipe, vegetations are effectively irrigated.

Description

technical field [0001] The invention relates to the technical field of irrigation systems, in particular to an artesian rainwater collection and irrigation system for green belts under viaducts. Background technique [0002] With the rapid growth of the national economy, the speed of urbanization in China is accelerating. In order to solve the urban traffic pressure, the main roads of many cities are already covered with viaducts. Due to the obstruction of the viaduct bridge deck, the green belt under the bridge deck is difficult. It directly receives rainwater irrigation; for green belts that cannot receive irrigation, the commonly used method is artificial irrigation; and this method not only wastes manpower and material resources, but also wastes rainwater resources. At the same time, rainwater is directly discharged into the sewer during heavy rains. Sewage systems put enormous pressure on them.
