Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural irrigation technical field especially relates to a farmland irrigation's water release well structure. BACKGROUND

[0002] Because of the insufficient water source condition, irrigation is carried out from the multi-stage water turning in the channel in some places. In the past, when the farmers pumped water for irrigation, they first constructed a water storage pool at a high place, and then newly built a channel from the water storage pool to farmland. Common channels include cast-in-place concrete channels, prefabricated U-shaped channels, brick channels and the like. Prefabricated U-shaped channels and brick channels are mostly used for small channels in rural areas. Because the channels often leak and are blocked, the water utilization coefficient is not high. Therefore, the open channel is adjusted to PE pipeline for irrigation, and the PE pipeline is directly connected from the outlet of the pump station to farmland. Because the water pump pumps water, the pressure at the water outlet is large, which easily causes the water flow to impact the field surface and form pits. Therefore, in order to facilitate irrigation and prevent the water flow from impacting the field surface, the utility model provides a farmland irrigation water release well structure.
