Steel bridge deck pavement interlayer bonding state monitoring system and void detection method
The invention relates to the technical field of orthotropic steel bridge deck pavement, and particularly relates to a steel bridge deck pavement interlayer bonding state monitoring system and a void detection method. The steel bridge deck pavement interlayer bonding state monitoring system comprises an interlayer sensor arranged in a waterproof bonding layer and fixed to the upper end of a steel bridge deck, and a demodulator, wherein an optical fiber is arranged in the interlayer sensor; the optical fiber is provided with a three-section grating in the interlayer sensor; and the demodulator is fixedly arranged on the edge side of a steel road, the demodulator and the interlayer sensor transmit signals through optical fibers, and the demodulator monitors the wavelength shift of the grating and calculates the size of an interlayer void. According to the invention, the optical fiber is arranged in the interlayer sensor, the optical fiber is provided with the three-section type grating, a vehicle load effect enables the interface deformation of the steel bridge deck and the pavement structure to be different, the wavelength deviation of the grating in the interlayer sensor is caused, monitoring is carried out through the wavelength deviation, and the interlayer void size is calculated; and therefore, the long-term tracking observation of the bonding state between the paving of the steel bridge deck 2 is realized, and the effective management and maintenance are achieved.
本发明涉及正交异性钢桥面板铺装技术领域，尤其涉及一种钢桥面铺装层间粘结状态监测系统及脱空检测方法，包括：层间传感器，设置在防水粘结层中，且固定于钢桥面板上端，层间传感器中设置有光纤，光纤在层间传感器中设置有三段式光栅；解调器，固定设置在钢路缘侧，解调器与层间传感器通过光纤传输信号，解调器对光栅波长偏移进行监测，并计算层间脱空大小。本发明中，层间传感器中设置有光纤，光纤设置有三段式光栅，车辆荷载作用使得钢桥面板与铺装结构界面变形出现差异，引起层间传感器中光栅波长的偏移，通过波长偏移进行监测，计算层间脱空大小，从而实现对钢桥面板2铺装间粘结状态的长期跟踪观测，达到有效管理养护。
