High-strain detection method for prestressed foundation pile
The invention belongs to the technical field of prestressed foundation pile detection, and discloses a high-strain detection method for a prestressed foundation pile. In order to solve the problems that an existing high-strain detection device is prone to toppling under eccentric hammer and a heavy hammer is prone to toppling, and a large potential safety hazard exists. The high-strain detection method makes full use of an existing prestressed foundation pile to fix a guide frame, and solves the problem that the guide frame cannot be stable in the field construction and a large potential safety hazard exists; and meanwhile, the guide frame is fixed to the prestressed foundation pile through a clamping device, and a vertical center line of the clamping device and a vertical center line ofthe heavy hammer are on the same straight line, so that the center position of the prestressed foundation pile can be hammered after the heavy hammer is free to fall, eccentric hammering is prevented,numerical values of sensors on the two sides of the prestressed foundation pile are quite close, the real bearing capacity and integrity of the prestressed foundation pile can be obtained conveniently, and the accuracy of the prestressed foundation pile detection is improved.
本发明属于预应力基桩检测技术领域，公开了一种预应力基桩高应变检测方法，为了解决现有高应变检测装置存在着偏心锤击以及重锤下落后容易倾倒而存在较大安全隐患的问题。本发明充分利用现有的预应力基桩将导向架进行固定，解决了在野外施工时导向架无法稳固而存在较大安全隐患的问题；同时导向架通过夹持装置固定在预应力基桩上，并且夹持装置的竖直中心线与重锤的竖直中心线在同一直线上，从而保证了重锤自由落下后能够锤击在预应力基桩的中心位置，防止出现偏心锤击，从而使得预应力基桩两侧传感器的数值非常接近，从而便于对数据进行分析得出预应力基桩真实的承载力和完整性，提高对预应力基桩检测的精度。
