Problems solved by technology

[0002] Among the existing farmland drainage technologies, most of them use open channel irrigation and open channel drainage technology. This technology not only needs to occupy a large amount of cultivated land, but also is inconvenient for agricultural machinery to work in the field.
Some farmlands already have low-pressure pipeline irrigation and underground pipe precipitation technology, but the pipe network of low-pressure pipeline water delivery irrigation cannot undertake the task of

Embodiment Construction

[0027] Farmland irrigation and drainage system, including pumping station 9, drainage pipe 12, main pipe 11, several branch pipes 6 buried below the ground, and several groups of buried pipes buried below the ground, the main pipes respectively pass through the pumping station, drainage pipe and water source Linked to each other, the drainpipe place is provided with gate valve well 10. The branch pipes are buried below the ground on the outside of the farmland ridge, and the hidden pipes are buried below the ground on the farmland surface. Each group of hidden pipes is composed of several porous pipes 7 (porous pipes are double-walled corrugated pipes with a number of pores, buried 80cm to 100cm below the surface of the farmland, and the critical depth of groundwater is 70cm below the ground. -80cm, the branch pipe and the hidden pipe are at the same depth), there are several holes on the pipe wall of each porous pipe, the ends of each group of porous pipes are connected to th...

Abstract

A farmland irrigation and drainage co-management system belongs to the technical field of hydraulic engineering. A multi-hole stain-reducing concealed conduit made of a double-wall corrugated pipe iscombined with a low-pressure pipeline system for irrigation, so that irrigation, drainage and lowering share a pipeline system, silt flushing and hole cleaning are realized by utilizing water pressurein a pipeline during irrigation, and sludge blockage is reduced. According to the invention, the problems of farmland irrigation, field surface drainage after rainstorm, soil water stain reduction after rainstorm, easy blockage of an underground porous double-wall corrugated pipe, sediment deposition during drainage in an irrigation pipeline, land occupation of farmland side irrigation channels and drainage channels, and pipeline clogging are effectively solved.

Description

technical field [0001] The invention relates to a farmland drainage and irrigation system, in particular to a farmland irrigation and drainage co-management system, which belongs to the technical field of water conservancy engineering. Background technique [0002] Among the existing farmland drainage technologies, most of them adopt open channel irrigation and open channel drainage technology. This technology not only needs to occupy a large amount of cultivated land, but also is inconvenient for agricultural machinery to work in the field. Some farmlands already have low-pressure pipeline irrigation and underground pipe precipitation technology, but the pipe network of low-pressure pipeline water delivery irrigation cannot undertake the task of drainage, and the surface water drainage task cannot be undertaken by the underground pipeline for precipitation reduction, and the outlet of the precipitation pipe must first be drained. After being discharged into the open ditch, ...
