弓形闸门属于受拉(压)构件,不论是钢筋混凝土或钢质的,都具有自重轻、省材料和造价低的优点,并很适宜配合螺杆启闭机使用。 自1965年10月我局指导海丰县水电局在公平干渠上设计试验第一扇净宽3.5米、门高2米、面板厚度4厘米的钢筋混凝土弓形门获得成功,以及普宁县水电局在练江水闸试验第一扇净宽4米、门高3.5米的弓形钢闸门,经过几个月的不断改进,也于同年10月试验成功。十年来我区已在海丰、陆丰、普宁、潮阳、饶平五县普遍使用,初步统计有中小型水库安上钢筋混
Bow-shaped gate belongs to the tension (pressure) components, whether reinforced or steel, have the light weight, the advantages of low cost and material, and is very suitable for use with screw hoist. Since October 1965, our bureau instructed Haifeng County Hydropower Bureau to design and test the first reinforced concrete arch gate with a net width of 3.5 meters, a gate height of 2 meters and a panel thickness of 4 centimeters at the fair trunk channel and the success of Puning County Hydropower Bureau The first gate of the river sluice test has a net width of 4 meters and a bow gate of 3.5 meters in height. After several months of continuous improvement, it was also successfully tested in October of the same year. Over the past 10 years, our district has been widely used in Haifeng, Lufeng, Puning, Chaoyang and Raoping five counties, preliminary statistics of small and medium-sized reservoirs on the reinforced
