汉川泵站承担汈汊湖区1936km~2的排涝和孝感地区南部四县180万亩农田的灌溉任务。泵站总容量为20,800kW。本文根据汉川泵站的运行实践和径流观测,研究分析了平原湖区暴雨的汇流规律,提出了泵站合理的调度准则:(1)合理控制起始排水位;(2)掌握雨情预报,坚持水位预降;(3)科学处理调蓄与抽排的关系;(4)河湖调蓄同时进行;(5)先排河渠、后吐湖泊;(6)坚持泵站经济运行;(7)掌握水情、力争自排。合理调度的直接经济效益是可减少漬涝面积10.8～32.6万亩,免损粮食3240～9780万kg。
Hanchuan pumping station to undertake Sui Lake area 1936km ~ 2 drainage and Xiaogan area four counties 1800000 acres of farmland irrigation task. The total pumping capacity is 20,800kW. According to the operation practice and runoff observation of Hanchuan Pumping Station, this paper studies the convergence rule of heavy rain in Pinghu Lake area, and puts forward the reasonable scheduling rules of pumping station: (1) Reasonably controlling the initial drainage level; (2) Grasping the forecast of rainstorm, insisting Water level pre-drop; (3) scientific handling of the relationship between regulation and pumping and pumping; (4) simultaneous regulation of rivers and lakes; (5) drainage of the river and vomit lakes; (6) adherence to the economic operation of pumping stations; Grasp the water, and strive to self-arrange. The direct economic benefits that can be reasonably dispatched can reduce the flooding area by 10.8 ~ 32.6 mu and the loss-free food by 3240 ~ 97.8 million kg.
