Construction method of underwater pile foundation steel sheet pile cofferdam
The invention discloses an underwater pile foundation steel sheet pile cofferdam construction method. The method comprises the following steps that S1, construction preparation is conducted, specifically, steel sheet piles, guide frames and limiting mechanisms are prepared; s2, installation of the guide frame, specifically, before the guide frame is installed, a forward intersection method is adopted for positioning, and after positioning, the guide frame is installed; s3, a limiting mechanism is installed, specifically, the limiting mechanism is adjustably installed on the guide frame, and preparation is made for follow-up limiting of the steel plate column; s4, steel plate piles are installed, specifically, the steel plate piles are sequentially installed at the guide frame, and the connecting positions of the adjacent steel plate piles are smeared with lubricating and sealing substances; s5, the steel plate piles are limited, specifically, all the steel plate columns are limited through a limiting mechanism; s6, the steel sheet piles are supported, specifically, the inner walls of the steel sheet piles are supported through inner supporting frames; s7, the guide frame and the limiting mechanism are dismounted; and S8, water pumping and leaking stoppage. Through the guide frame and the limiting mechanism, the mounting precision of the steel sheet pile is guaranteed, and deflection of the steel sheet pile is avoided.
本发明公开了一种水中桩基钢板桩围堰施工方法，包括以下步骤：S1：施工准备：准备钢板桩、导向框以及限位机构；S2：导向框的安装：导向框安装前，采用前方交会法进行定位，定位后再安装导向框；S3：限位机构的安装：将限位机构可调节的安装在导向框上，为后续钢板柱的限位做准备；S4：钢板桩的安装：将钢板桩依次安装在导向框处，将相邻钢板柱的连接处涂抹润滑密封物质；S5：钢板桩的限位：通过限位机构对各个钢板柱进行限位；S6：钢板桩的支撑：通过内支撑架对钢板桩的内壁进行支撑；S7：导向框和限位机构的拆除；S8：抽水堵漏。本发明，通过导向框和限位机构，保证了钢板桩安装的精度、避免其歪斜。
