黄河下游移动式不抢险潜坝试验工程结构设计

Structure design on pilot project of movable and unemergency submerged dam in Yellow River downstream

根据黄河下游移动式不抢险潜坝应用研究项目任务,选择在郑州惠金河务局南裹头工程下首滩岸修建试验潜坝,设计中首次采用预应力混凝土管桩、预制混凝土连接销轴、连系帽梁有机组合的拼装式结构,实现了不抢险潜坝的简便拼装、拆卸和移动。实践证明该潜坝作为黄河下游河道整治的一种新坝型结构具有广阔应用前景。

In line with study project tasks of pilot project of movable and unemergeney submerged dam in Yellow River downstream, the bank in the lower reaches of the Nanguotou Scheme of Zhengzhou Huijin River Authority is selected to build submerged dam. In the design of the dam, prestressed high strength concrete pipe piles, pin-connected boom and tie bent cap are firstly introduced, so as to realize simple installation and remove. It is demonstrated that the submerged dam has a wide application as a new type of dam structure for river training in the downstream of the Yellow River.
