Steel pipe pile structure additionally arranged on basement raft and construction method of steel pipe pile structure
The invention relates to the technical field of constructional engineering, in particular to a steel pipe pile structure additionally arranged on a basement raft and a construction method thereof.The steel pipe pile structure additionally arranged on the basement raft comprises a steel pipe pile body, and a pile pressing hole for containing the steel pipe pile body is formed in the raft. An inverted-U-shaped rib and a short steel bar are welded to the end of the steel pipe pile body, a cushion layer is arranged below the raft, an annular water stop device is arranged on the side wall of the pile pressing hole, and the gap between the steel pipe pile body and the pile pressing hole is filled with micro-expansion concrete. The pile pressing hole is of a big-end-up inverted-splayed structure or a structure with an upper cylinder and a lower circular truncated cone. According to the steel pipe pile structure, the original structure does not need to be shored and unloaded, large-range chiseling-off operation does not need to be conducted on a basement raft, large equipment is not needed, the workload is greatly reduced, and the working efficiency is improved; the construction method of the steel pipe pile structure is flexible and changeable, is not limited by the field environment, and is high in adaptability.
本发明涉及建筑工程技术领域，尤其是一种在地下室筏板上补设的钢管桩结构及其施工方法，在地下室筏板上补设的钢管桩结构包括钢管桩本体，所述的筏板上设有放置钢管桩本体的压桩孔，所述的钢管桩本体端部焊接有倒U形筋和短钢筋，所述的筏板下设有垫层，所述的压桩孔侧壁上设有环形止水装置，所述的钢管桩本体与压桩孔空隙间填充满微膨胀混凝土，所述的压桩孔采用上大下小的“倒八”形结构或者上圆柱下圆台的结构。本发明的钢管桩结构，不需要对原结构进行顶撑、卸荷，不需要对地下室筏板进行大范围凿除作业，无需大型设备，大大降低了工作量，提高了工作效率；本发明钢管桩结构的施工方法，灵活多变，不受现场环境的限制，适应性强。
