The invention discloses an underwater piling and bearing platform cofferdam construction method and a bearing platform enclosure structure. The method comprises the steps that firstly, the positions of precast piles are positioned; steel pipe piles are driven into preset positions, and a steel platform is erected on the upper portions of the steel pipe piles; the precast piles are driven by means of the steel platform; and after the precast piles are driven, the steel platform is dismantled, a guide frame is arranged at the outer sides of the precast piles, and an cofferdam is manufactured through components of the steel platform. According to the construction method, coherent construction is conducted on the precast piles and the bearing platform, the construction coherence is guaranteed, the construction time of a pile foundation and the bearing platform is shortened, and the construction efficiency can be greatly improved. Through secondary utilization of steel pipe piles and profile steel used by the precast piles, the cofferdam structure is arranged, so that the waste of temporary facilities is reduced, and the utilization efficiency of materials is improved.
本发明公开了一种水中打桩及承台围堰施工方法、承台围护结构，首先，对预制桩的位置进行定位；在预先设定的位置打入钢管桩，在钢管桩的上部搭设钢平台；借助该钢平台打入预制桩；预制桩打完后拆除钢平台，并在预制桩的外侧设置导向架，利用钢平台的部件制作围堰。本发明对预制桩及承台进行了连贯施工，保证了施工的连贯性，缩短了桩基及承台的施工时间，可大大提高施工效率。通过对预制桩使用的钢管桩及型钢的二次利用，设置围堰结构，减少了临时设施的浪费，提高了材料的利用效率。
