台州市引水工程—椒江管线水上勘察施工方案

The Over-water Geological Working Scheme of Taizhou Water Diversion Project on Jiaojiang River

台州市引水工程椒江段管线位于椒江大桥上游1 500m,管线全长1 300m,呈"之"字形布置,沿管线两侧共布置38个钻孔。首先调查了水上勘察作业区航线位置及船舶通行情况,提出了钻探船与警戒船的布置方案;其次根据潮汐规律提出了施工作业时间;最后提出了施工建议。

The pipeline of Taizhou Water diversion project is 1 300 meters long and located 1 500 meters in the upper Jiaojiang Bridge. 38 drilling holes are zigzagged along the pipelines. In order to perform the over-water construction,the route along with the vessel traffic issues are firstly investigated,the layout scheme of drilling operation ship and guard-ship is then made. Secondly,the construction time of drilling operation ship is planned according to the tidal law. Lastly,the construction suggestion is proposed.
