Construction method and device for recycling deepwater pile foundation steel casing
The invention discloses a deep water pile foundation steel casing recycling construction method and device. A first steel casing and a second steel casing are prepared, the inner diameter of the first steel casing is 30-40 cm larger than the outer diameter of the designed pile, the inner diameter of the second steel casing is equal to the outer diameter of the designed pile, and the height of the second steel casing is at least 1 m higher than the top of the designed pile; a through hole is formed in a panel of the steel platform, and a guide frame is arranged at the through hole and the position 3 m below the through hole; the first steel casing is fixedly connected with the steel platform; a second steel casing is lowered, a plurality of hanging rods are arranged in the circumferential direction of the top of the second steel casing, and the second steel casing is prevented from inclining in the lowering process; after the second steel casing is lowered in place, the ends, away from the second steel casing, of the multiple suspenders are fixedly connected to the side, away from the riverbed rock layer face, of the first steel casing; and when pile foundation concrete pouring is completed and the concrete age meets the standard requirement, the first steel casing is pulled out and circulated to the next working face.
本申请公开了一种深水桩基钢护筒循环使用施工方法及装置。制备第一钢护筒和第二钢护筒，第一钢护筒的内径比设计桩的外径大30‑40cm，第二钢护筒的内径等于设计桩的外径，第二钢护筒的高度比设计桩顶高出至少1m；在钢平台的面板上开设通孔，并在通孔及通孔以下3m处设置导向架；将第一钢护筒和钢平台固定连接；下放第二钢护筒，并在第二钢护筒的顶部的周向设置多个吊杆，避免第二钢护筒在下放过程中发生倾斜；当第二钢护筒下放到位后，将多个吊杆远离第二钢护筒的一端固定连接于第一钢护筒远离河床岩层面的一侧；当桩基混凝土灌注完成且混凝土龄期满足规范要求时，拔出第一钢护筒并循环至下一个工作面。
