目前,全省小型水库均采用开敞式溢洪道,大部分为山丘区季节性雨源型水库,主要靠汛期蓄水。由于建库时质量差,加之运行几十年,普遍存在病险隐患,效益较差。把活动式充水橡胶闸应用在小型水库溢洪道中,克服了永久固定橡胶坝管理周期长、使用寿命低等弱点,有利于水库发挥效益。在汛期需要蓄水时,充水启用,待灌溉用水降至闸底板以下时,拆除存放, At present, all the small reservoirs in the province adopt open spillways, most of which are seasonal rain-source reservoirs in hillside areas, mainly storing water in flood season. Due to the poor quality of the construction of the library, combined with running for decades, there are common hidden dangers, less effective. The application of movable water filled rubber gate in small reservoir spillway overcomes the long management cycle of permanent fixed rubber dam and low service life, which is beneficial to the reservoir. When it is necessary to store water during the flood season, water filling is enabled and until the water for irrigation falls below the gate of the floodgate, the storage is removed,
