In which , it gives inquiring of the construction of deep - water foundations and the usage of floating crane . the construction program of bridge pier foundation will be fixed according to the water depth . if the water depth is less than 4m , pier foundation will adopt the method of building island by earth filling ; if the water depth is more than 4m and there is over burden at river bed , at the same time , it has sufficient bearing capacity to load steel pipe pile , the steel pipe pile platform will be adopted 其中，对深水基础的施工及浮吊的使用进行了探讨，根据水深确定桥墩基础的施工方法，对水深不超过四米的桥墩基础，采用填土筑岛的方法：对水深大于四米，河床有覆盖层，且能保证钢管桩具有足够的承载力的桥墩，采用钢管桩平台；对主河道上河床没有覆盖层，钢管桩无法插打的桥墩，采用浮式平台。

If there is no over burden at the river bed , the steel pipe pile cannot be inserted , the floating platform will be adopted , during overwater construction , the author ( using zhong - 60 floating box , etc . ) assembled 40t floating crane by his own design , in this way , the floating crane completed the work of overwater transporting and lifting , such as the transporting of s teel pipe pile , inserting , the erecting of overwater construction platform , overwater moving of drill grid crane , lifting of lifting box of cushion cap , pulling out of steel pipe pile 在水上作业中，作者利用中- 60浮箱等设备自行设计、拼制了40t浮吊，完成了水上运输、水上起重等作业，如钢管桩的运输、插打、水上施工平台的搭设、钻机吊车的水上转移、承台吊箱的起吊、钢管桩的拔除等作业。
