极限工况条件下围堤充砂袋施工技术

针对温州鳌江口涌浪大、距离远的极限工况,在普通吹砂船无法施工的情况下,采取了自行改造吹砂驳船,陆地建造砂库配合泥浆泵、高压冲水及接力泵站等一系列措施,成功实现了将皮带砂1 500 m以上距离直接灌袋、吹砂库,克服了远距离充砂袋无法实施的困难,取得了重大突破,对我国沿海地区类似工况的充砂袋施工具有借鉴意义。

Construction techniques of artificial sand-filled bags under extreme working conditions

Under the situation that general sand-blowing vessel can not work in the extreme conditions of the heavy swell and long distance in Aojiangkou project,Wenzhou,we take the measures of remolding the sand-blowing barge,constructing onshore sand store coordinated with mud pump,high-pressure flush water and relay pump station etc.to fill the on-belt sand into bags and carry them to the sand store at the distance of 1 500 m,which overcomes the hardship of long-distance filling bags and achieves a great breakthrough.It may serve as reference for the filling-bag construction in the coastal areas with similar work conditions in China.
