低水头栏河闸坝钢丝网水泥闸门(一般用钢丝网水泥面板,钢筋混凝土或预应力钢筋混凝土梁和弧形门支腿)的门重比钢门大二至三倍,但用钢量只约为钢门的40%,造价相当于钢门的40～55%.解决门重所给启闭带来困难的办法,除尽量选用弧形门减轻启门力外,主要是改进启闭设备,用省力滑轮的装置,一台机启多门.吴川县在兴建河闸工程中,为了节省资金和钢材,除六十年代初,兴建了一些钢质门外,其后十多年,对于较大型的栏河闸都
The gate weight of a low headlamp dam, a steel mesh cement gate (usually steel mesh concrete panels, reinforced concrete or prestressed reinforced concrete beams and arcuate door legs), is three to four times larger than a steel gate, but with steel only About 40% of the steel door, the cost is equivalent to 40 ~ 55% of the steel door.How to solve the problem of door opening and closing to bring difficulties, in addition to try to use the arc door to reduce Kai door, the main improvement is the opening and closing equipment , With labor-saving pulley device, a machine to open more doors.Wuchuan County in the construction of Hezha project, in order to save money and steel, in addition to the early sixties, the construction of a number of steel doors, then more than 10 years, for Larger bar river gates
