Pier reinforcing structure and monitoring method thereof
The invention relates to a pier reinforcing structure and a monitoring method thereof, in particular to the technical field of bridge engineering. The device comprises a bridge pier, a steel bar planting hole, an L-shaped steel bar, a pipeline, piezoelectric intelligent elements, a connecting line, a signal generator, a steel formwork, a PZT strain gauge and a signal acquisition system, the signal generator is used for applying an electric excitation signal to one or more piezoelectric intelligent elements, driving piezoelectric ceramics in the piezoelectric intelligent elements are driven to generate vibration, vibration waves are diffused outwards, and the piezoelectric intelligent elements are driven to generate vibration. The PZT strain gauges at the measuring points receive vibration signals and convert the vibration signals into electric signals, the electric signals are collected by the signal collecting system, and time domain analysis, frequency domain analysis and time-frequency domain analysis are carried out on the collected signals so as to monitor the bonding condition of the externally-wrapped reinforced concrete and the old pier and evaluate the reinforcing effect. The technical problems that the combination condition between new concrete and old concrete is actively monitored, and the pier reinforcing effect is effectively evaluated are solved.
本发明涉及一种桥墩加固结构及其监测方法，特别涉及桥梁工程技术领域。该发明包括桥墩、植筋孔、L型钢筋、管道、压电智能元件、连接线、信号发生器、钢模板、PZT应变片、信号采集系统，用信号发生器对单个或者多个压电智能元件施加电激励信号，压电智能元件内的驱动压电陶瓷受到驱动会产生振动，振动波向外扩散，由测点处的PZT应变片进行振动信号的接收，并转换为电信号，电信号被信号采集系统收集，对所采集信号分别进行时域、频域、时频域分析，用以监测外包钢筋混凝土与旧桥墩的粘结情况，评估加固效果，解决了对新旧混凝土间的结合情况进行主动监测、对桥墩加固效果进行有效评估这一技术难题。
