Construction method for foundation adjacent to deep cutting precipice
The invention relates to a construction method of a foundation adjacent to a deep cliff, which comprises the following steps of: performing first local island construction at the position adjacent to the deep cliff in a dry season, and arranging a shortcut leading to the bottom of the deep cliff; a cofferdam is installed in the cofferdam construction area, so that the cofferdam, the deep cliff wall and the original riverbed surface jointly form a water blocking structure; second-time full-range island building construction is conducted between the inner side of the cofferdam and the deep cutting precipice, and a drilling pile working platform is formed; drilling pile construction is conducted on the drilling pile working platform; and carrying out bearing platform construction. The advantage of the near shore is fully utilized, the shortcut is introduced from the bottom of the deep cliff wall in the dry season, the shortcut enters the cofferdam through the shortcut in the later period, overwater construction is changed into pure land construction, and the construction cost is greatly saved; the advantages of work starting in the dry season are fully utilized, the cofferdam installation condition can be met only through local island building, and a working face can be rapidly formed after work starting and entering; the cofferdams and the deep cliff wall jointly form a water blocking structure, and the topographic features of the deep cliff wall are fully utilized.
本申请涉及一种邻近深切崖壁基础施工方法，其包括：枯水期时在临近深切崖壁处进行第一次局部筑岛施工，并设置通往深切崖壁底部的便道；在围堰施工区域处安装围堰，使围堰、深切崖壁和原始河床面共同形成阻水结构；在围堰内侧与深切崖壁之间进行第二次全范围筑岛施工，形成钻孔桩工作平台；在钻孔桩工作平台上进行钻孔桩施工；进行承台施工。本发明充分利用了近岸的优势，枯水期时自深切崖壁底部引入便道，后期通过便道进入围堰内，变水上施工为纯陆地施工，极大节约了施工成本；充分利用枯水期开工优势，仅需局部筑岛即可满足围堰安装条件，可在开工进场后快速形成作业面；围堰与深切崖壁共同构成阻水结构，充分利用了深切崖壁的地形特征。
