Karez type irrigation and drainage corridor built in arid irrigation area
The invention relates to the technical field of irrigation and drainage galleries, in particular to a karez type irrigation and drainage gallery built in an arid irrigation district, which comprises a field irrigation system, at least two underground water collection galleries and a self-flowing water delivery pipe, the irrigation district is internally provided with at least two underground water collection galleries, and each underground water collection gallery comprises a tube well, a communicating tube and a plurality of radiation wells arranged at intervals. The device is reasonable and compact in structure and convenient to use, the underground water collecting gallery is automatically guided out of the ground through the automatic-flow water conveying main pipe according to the terrain gradient of an irrigation area, on one hand, a large amount of power consumption is saved, on the other hand, automatic-flow water diversion is limited by the water level, water is taken at the fixed water level, and the exploitation amount of underground water can be automatically controlled; and the underground water can not be overexploited.
本发明涉及灌溉与排水廊道技术领域，是一种建筑在干旱区灌区的坎儿井式灌溉与排水廊道，其包括田间灌溉系统、地下集水廊道、自流输水管，灌区内设至少两条地下集水廊道，地下集水廊道包括管井、连通管和若干间隔设置的辐射井。本发明结构合理而紧凑，使用方便，根据灌区地形坡度，通过自流输水干管将地下集水廊道自流引出地面，一方面节省了大量的电力消耗，另一方面，自流引水，其水量受水位的限制，是定水位取水，它可以自动控制地下水的开采量，不会也没有能力超采地下水。
