Construction method for forming steel pipe pile on deepwater and torrent inclined rock bed
The invention provides a construction method for forming a steel pipe pile on a deepwater torrent inclined rock bed, which comprises the following steps of: S10, designing a jacket, transporting the jacket in place by using a transport ship, and inserting and driving the steel pipe pile; s20, temporarily fixing the jacket and the steel pipe pile by using a steel bar; s30, brackets are welded to the steel pipe piles; s40, the jacket is supported by brackets, and anchor piles are constructed; s50, a lifting and lowering system is installed; s60, a steel bar is inserted into the hole flitch plate for reinforcement; s70, corbels are dismantled, and the steel pipe piles and the jacket are connected and fixed through stiffening plates; s80, a gap between the outer sleeve and the steel pipe pile is plugged through a water stopping capsule; s90, cement paste is injected between the outer sleeve and the steel pipe pile in a pressed mode; and S100, pile caps are mounted at the tops of the steel pipe piles. The problem that the steel pipe piles on the deepwater and torrent inclined rock bed are difficult to insert and drive is solved, and the construction difficulty of underwater welding of a connecting system between the steel pipe piles is avoided.
本发明提供了一种深水急流倾斜岩床上钢管桩成桩的施工方法，包括以下步骤：S10、设计导管架并使用运输船将导管架运输到位，插打钢管桩；S20、使用钢棒将导管架和钢管桩临时固定；S30、在钢管桩焊接牛腿；S40、导管架由牛腿支撑，施工锚桩；S50、安装提升下放系统；S60、将钢棒插装洞口贴板补强；S70、拆除牛腿，使用加劲板将钢管桩和导管架连接固定；S80、使用止水胶囊封堵外套管和钢管桩之间的缝隙；S90、在外套管和钢管桩之间压注水泥浆；S100、在钢管桩顶部安装桩帽。本发明克服了深水急流倾斜岩床上钢管桩难以插打的难题，避免了水下焊接钢管桩间连接系的施工难度。
