摘要
结合温福铁路浙江段飞云江特大桥水中4、5号墩基础施工中的钻孔平台形成及钻孔桩施工生产实践,介绍了采用水下包封混凝土施工钻孔平台的方法解决水中墩倾斜裸岩河床区钢护筒无法插打,在潮汐作用下无法形成牢固的钻孔平台的施工难题,为潮汐地区复杂地质情况下大中型桥梁基础施工积累经验。
The paper gives the summary to the construction technology of the drilling platform and the bored pile for the foundation construction of 4# and 5# underwater piers of the Feiyun Jiang River Super Large Bridge of Zhejiang Section of the Wenzhou--Fuzhou Railway. And it also accumulated the experience for the foundation construction of the large and middle bridges under the complex geological condition in the tidal area.
