Construction method for cutting underwater cast-in-place pile by using steel casing and assisting rope saw
The invention discloses a construction method for cutting an underwater cast-in-place pile through a steel casing and an auxiliary rope saw. The construction method specifically comprises the following steps of construction preparation, steel casing machining, steel casing in-place, mud pumping and water draining, cutting system installation, pile foundation cutting and broken pile body hoisting and discarding. The steel pile casing is driven into a soil layer to form an enclosure system, so that the cutting stress condition of a cutting system formed on I-shaped steel by a hydraulic diamond bead rope sawing machine during cutting operation is met, the safe operation of cutting the underwater cast-in-place pile is realized, and meanwhile, the pile foundation cutting elevation position required by design is met. The bottom of the steel casing adopts a conical section, a vibratory hammer sinks into the periphery of a cutting pile to form an enclosure system, the dredging and sludge discharging amount of the periphery of the cutting pile can be greatly reduced, meanwhile, a safe construction working face is provided, the steel casing and the enclosure system of the steel casing effectively form a working whole through a clamping plate and a limiting plate, an operator can remotely control, and the working efficiency is improved. The sealing working time is shortened, and efficient and safe operation is fully achieved.
本发明公开了钢护筒辅助绳锯切割水下灌注桩施工工法，具体包括如下步骤：施工准备→钢护筒加工→钢护筒就位→抽泥排水→切割系统安装→桩基切割→吊离破碎桩体废弃。本发明采取钢护筒打入土层形成围护系统达到满足液压金刚珠绳锯机在工字钢上形成的切割系统在切割作业时的切割受力条件，实现切割水下灌注桩安全作业，同时满足设计要求的桩基切割标高位置。钢护筒底部采取锥形截面，采用振动锤沉入切割桩周围形成围护系统，可大幅度减少切割桩周边的清淤排泥量，同时提供安全施工作业面，通过卡板和限位板，有效地与钢护筒围护系统形成一个工作整体，操作人员可远程进行操控，缩短密闭工作时间，充分实现高效、安全作业。
