摘要
在重力式码头的施工中,由于操作失误或不可控因素的影响,可能导致预制好的沉箱下沉或滑移,在最低潮位时沉箱顶仍在水面以下,无法正常从沉箱内抽水浮起沉箱,从而影响工程的顺利进展,给工程造成巨大的损失。采用预制钢盖板对沉箱进行封仓,然后抽水,利用沉箱自身所受浮力将沉箱浮出水面的方法成功地解决了这个难题。本文对此次打捞施工进行详细的介绍,并总结处理类似情况的方法、经验和注意事项。
During the construction of gravity wharf,caisson may sink or slip into the water due to the miss operation or other uncontrollable factors,which will affect the smooth implementation of engineering and bring a huge loss.In practice,by patching the caisson with the prefabricated steel cover plate and pumping,the caisson floated off the water surface under the buoyance and the problem was solved.This paper gives a detailed description of the refloating construction,and summarizes the methods,experience and matters of attention when dealing with similar problems.
