The invention discloses a concrete pile crack monitoring device and a monitoring method thereof, and relates to the technical field of concrete pile foundation crack monitoring, the device comprises a signal generation module, a signal collection module and a piezoelectric ceramic piece, the signal generation module comprises a signal generation device and an amplification device, the signal generation device is electrically connected with the amplification device, and the signal collection module is electrically connected with the piezoelectric ceramic piece. The piezoelectric ceramic piece is fixed to the reinforcement cage, the positive electrode of the piezoelectric ceramic piece is connected to one end of the positive wire, the end, away from the piezoelectric ceramic piece, of the positive wire can be electrically connected with the amplifying device and the signal collecting module, and the negative electrode of the piezoelectric ceramic piece is connected to one end of the negative wire. The end, away from the piezoelectric ceramic piece, of the negative wire can be electrically connected with the amplifying device and the signal collecting module. The monitoring method comprises the steps of piezoelectric ceramic piece preparation, concrete pile pouring, initial measurement calibration and active monitoring. Whether the crack exists or not, the position of the crack distance sensor and the crack development width change can be accurately reflected only by arranging one piezoelectric ceramic piece.
本发明公开了一种混凝土桩裂缝监测装置及其监测方法，涉及混凝土桩基裂缝监测技术领域，其中装置包括信号发生模块、信号收集模块和压电陶瓷片，信号发生模块包括信号发生装置和放大装置，信号发生装置和放大装置电连接，压电陶瓷片固定于钢筋笼上，压电陶瓷片的正极连接于正极导线一端，正极导线远离压电陶瓷片一端能够分别与放大装置和信号收集模块电连接，压电陶瓷片的负极连接于负极导线的一端，负极导线远离压电陶瓷片的一端能够分别与放大装置和信号收集模块电连接。监测方法包括制备压电陶瓷片、浇筑混凝土桩、初测标定和主动监测。本发明仅需设置一个压电陶瓷片就能够准确地反映裂缝是否存在、裂缝距离传感器的位置以及裂缝开展宽度变化。
