摘 要:延安黄河引水工程地处黄河中游,冬季冰情复杂,取水口宜受结冰和雍冰淤堵,影响取水安全,考虑冬季取水口引水要求,拟在取水口设置防冰冻装置,确保取水口不受冰冻影响,根据取水口金属结构布置、河道冰情、泥沙、气温等因素选择合理的防冰冻装置是取水口防冰冻成败的关键。The Yan'an Yellow River Water Diversion Project is located in the middle reaches of the Yellow River.The ice conditions in winter are complex,and the water intake should be blocked by icing and icy ice,which affects the safety of water intake.Considering the water intake requirements in winter,it is proposed to install an anti-icing device at the intake to ensure that the intake is not affected by freezing.According to the metal structure arrangement of water intake,river ice situation,sediment,air temperature and other factors,the selection of reasonable anti-freezing device is the key to the success of anti-freezing of water intake.
