Rapid construction method for steel pipe pile cofferdam
The invention provides a rapid construction method for a steel pipe pile cofferdam. The rapid construction method comprises the following steps that steel pipe piles, surrounding purlins, inner supports and force transmission pieces are manufactured in a backfield; the assembling brackets are used when the cofferdam is assembled; the enclosing purlins and the inner supports are assembled into an integral frame type on the assembling brackets, the sides, away from the sliding grooves, of the force transmission pieces are hung on the assembled enclosing purlins, and a lowering system is arranged; the assembled brackets are dismantled, and the overall frame type enclosing purlin inner support is synchronously lowered to the designed position through the lowering system; the steel pipe piles are inserted and driven in place along the sliding grooves and closed, and grouting is conducted through grouting pipes reserved on the steel pipe piles, so that the periphery of the cofferdam is dense and free of water leakage; and sealing the bottom in the cofferdam underwater, and pumping water to construct the bearing platform after the designed strength is reached. The steel pipe piles are closely attached to the force transmission pieces, the cofferdam is good in integrity, high in precision and reliable in stress, no guiding for inserting and driving needs to be additionally arranged, and the construction period, quality, safety and economical efficiency are remarkable.
本发明提供一种钢管桩围堰快速施工方法，包括以下步骤：后场制作钢管桩、围檩、内支撑及传力件；安装拼装围堰时用的拼装牛腿；在拼装牛腿上将所述围檩和内支撑拼装成整体框架式，将所述传力件远离所述滑槽的一侧挂在拼装后的围檩上，设置下放系统；拆除所述拼装牛腿，通过所述下放系统将整体框架式的围檩内支撑同步下放至设计位置；沿所述滑槽将钢管桩插打到位并合龙，通过所述钢管桩预留的压浆管注浆使围堰四周密实不漏水；围堰内水下封底，达到设计强度后抽水施工承台。本发明钢管桩与传力件密贴，围堰整体性好、精确度高、受力可靠，且无需另外设置插打的导向，工期、质量、安全及经济性显著。
