引言在拦河坝上采用升卧式平面闸门,是我地区首次应用的一种新门型,经过在岑溪县波圹水电工程大坝上运行两年的检验,闸门启闭灵活,效果良好。这种门型在启门时首先直升一段,然后边上升边向下游转动,至闸门全开时成为水平状态,平卧于闸墩顶部。它与直升式平面闸门相比。既能降低启闭台的高度、便于施工、投资省,又能提高水工建筑物的抗震能力;与弧形闸门比较,亦具有闸墩短,结构简单,建筑物工程量小等优点。故在坝前校核洪水位较高的闸坝工程上采用这种门型,在技术上是可行的,经济上也是合理的。现予简介供参考。
Introduction In the barrage using horizontal plane gate, is the first time in our region a new type of portal, after Cenxi County Bo Yang hydropower dam running two years of inspection, gate opening and closing flexible, good effect. This type of door in the door when the first helicopter helicopter, and then while the lower edge of the rising edge of the rotation to the gate fully open to a horizontal state, lying in the top of the pier. It is compared with the helicopter flat gate. The utility model not only can reduce the height of the opening and closing platform, is convenient for construction and investment, and can also improve the seismic capacity of hydraulic structures. Compared with the arc gate, the utility model also has the advantages of short pier, simple structure and small construction volume. Therefore, it is technically feasible and economically reasonable to adopt such a gate type in the project of gate dam with a high flood water level in front of the dam. Now for reference for reference.
