High-strength prestressed pipe pile pulling resistance detection device and detection method thereof
The invention discloses a high-strength prestressed pipe pile pulling resistance detection device and a detection method thereof. The device comprises at least two buttresses which are poured on a top excavation surface of a pipe pile and are respectively arranged on two opposite sides of the pipe pile; the jacking jack is vertically arranged on the buttress; the jacking jacks on the buttresses on the two opposite sides of the pipe pile are supported at the two ends of the bearing beam respectively, a plurality of penetrating holes are formed in the middle of the bearing beam, the prestressed steel bars of the pipe pile extend to the position above the upper end face of the pipe pile, and the vertical main ribs of the filling core in the pipe pile extend to the position above the upper end opening of the pipe pile. The prestressed steel bars and the vertical main reinforcements are movably arranged in the penetrating holes in a penetrating mode and extend to the positions above the supporting beams, anchorage devices are installed at the upper ends of the prestressed steel bars and the upper ends of the vertical main reinforcements, and the supporting beams are supported on the anchorage devices. The problem that the pile core filling core is easy to pull out during uplift detection of the high-strength prestressed pipe pile in offshore engineering, and the uplift bearing capacity requirement during detection cannot be met is solved.
本发明公开了一种高强预应力管桩抗拔检测装置及其检测方法，包括：浇筑于管桩的顶部开挖面的至少两支墩，至少两支墩分别设置于管桩的相对两侧；顶升千斤顶，竖设于支墩上；支承梁，管桩的相对两侧的支墩上的顶升千斤顶分别支撑于支承梁的两端，支承梁的中部开设有多个穿孔，管桩的多根预应力钢棒伸至管桩的上端面的上方，管桩内的填芯的多根竖向主筋伸至管桩的上端口的上方，预应力钢棒和竖向主筋可活动地穿设于穿孔并伸至支承梁的上方，预应力钢棒和竖向主筋的上端安装有锚具，支承梁支撑于锚具。本发明解决了在近海工程中高强预应力管桩抗拔检测时容易出现桩芯填芯拔出，无法满足检测时的抗拔承载力要求的问题。
