Double-wall steel hanging box cofferdam construction method capable of providing drilling platform
The invention relates to the technical field of deepwater foundation construction, and discloses a double-wall steel hanging box cofferdam construction method capable of providing a drilling platform. The construction method of the double-wall steel hanging box cofferdam capable of providing the drilling platform comprises the following steps that S1, a double-wall steel hanging box and a cofferdam are assembled to form a rectangular platform; s2, a kerosene permeation experiment is conducted on the interior of the cofferdam, and it is guaranteed that all inspection items of S3, making a water line mark on an outer side wall plate of the cofferdam, and hoisting the cofferdam into water; and S4, after the cofferdam enters the water, the cofferdam is integrally conveyed to the position of a pier in a floating mode for preliminary positioning, after preliminary positioning is completed, directional steel protection cylinders are inserted and hit through a floating crane, the double-wall steel hanging box and the cofferdam are spliced through installed T-shaped embedding pieces, triangular embedding frames and sealing pieces, a rectangular platform is formed, and the cofferdam is placed in the rectangular platform. And a positioning ship is matched to carry out mobile positioning in an integral floating transportation mode, so that the difficulty of operation in the sea is reduced, and the construction quality is improved.
本发明涉及深水基础施工技术领域，且公开了一种能够提供钻孔平台的双壁钢吊箱围堰施工方法。该一种能够提供钻孔平台的双壁钢吊箱围堰施工方法，包括以下步骤：S1.拼装双壁钢吊箱和围堰，形成长方形平台；S2.对围堰内部进行煤油渗透实验，保证围堰各项检验合格；S3.在围堰的外侧壁板上做水位线标记，将围堰吊装下水；S4.在围堰下水后采用整体浮运至桥墩位置处进行初步定位，初步定位完成后利用浮吊插打定向钢护筒，通过安装的T型嵌合件、三角嵌合架和密封件，对双壁钢吊箱和围堰进行拼装，形成一个长方形平台，再配合定位船采用整体浮运的方式进行移动定位，减少了海中作业的难度，提高了施工的质量。
