Underground pipe irrigation system and construction method thereof for sponge city

Abstract

The invention discloses an underground pipe irrigation system and a construction method thereof for a sponge city. The system comprises infiltration pipes, a regulating box, a flow-spitting box and pressurized tanks. The infiltration pipes are evenly distributed on diversion pipes which are connected to the regulating box through a collecting pipe; the diversion pipes and the collecting pipe are connected through a triple valve; the regulating box is connected with the flow-spitting box through a water transmission pipe; the water transmission pipe is provided with a water suction pump; the flow-spitting box is connected to the pressurized tanks through the diversion pipes; the pressurized tanks are connected with underground pipes. The method comprises following steps: underground pipe layout, flow-spitting box construction, regulating box construction, infiltration pipe construction and the operation of the irrigation system. The method of the invention has simple steps, rainwater is effectively collected so as to be used for underground irrigating; therefore, water accumulation is effectively reduced; waste of water resource is reduced; rainwater reclamation is facilitated; the construction method can meet the needs of irrigation in cities having different terrains.

Description

technical field [0001] The invention relates to an underground underground pipe irrigation system for a sponge city and a construction method thereof. Background technique [0002] Subsurface irrigation refers to the introduction of irrigation water to a certain depth below the field surface, through soil capillary action, to moisten the soil in the root zone for the needs of crop growth. [0003] Underground irrigation in the prior art generally directly uses groundwater or directly introduces water in the river to farmland for irrigation. These two irrigation methods are easily affected by water source pollution, which is not conducive to farmland irrigation, and the water after irrigation is directly discharged into the river. , causing secondary pollution to the river. Contents of the invention [0004] The purpose of the present invention is to provide a technical scheme of a sponge city underground pipe irrigation system and its construction method in view of the de...
