Prefabricated pipe gallery assembling system
The invention provides a prefabricated pipe gallery assembling system which comprises a plurality of tensioning devices, a plurality of tensioning adjusting devices and a control device. Each tensioning device comprises a steel strand and a tensioning drive, wherein the steel strand penetrates through tensioning holes of two adjacent pipe gallery sections, the tensioning drive is used for tensioning the steel strand, and an optical fiber is arranged in the steel strand; the tension adjusting device comprises a collector used for collecting and demodulating tension data and an optical fiber sensor in communication connection with the collector, and the optical fiber sensor is used for detecting the wavelength change of the optical fiber and is arranged in the steel strand; the control device is in communication connection with the tensioning adjusting device and the tensioning drive. The optical fiber is arranged in the steel strand, and the optical fiber strain is monitored in real time through the optical fiber sensor and the collector, so that the tension stress of the steel strand can be regulated and controlled in real time, the tension force of each tension point is ensured to be greater than a preset value, the tension quality is ensured, the sealing performance of the pipe gallery section is improved, and the normal operation and maintenance of the pipe gallery can be ensured.
本发明提供一种预制管廊拼装系统，包括多个张拉装置、多个张拉调节装置和控制装置：张拉装置包括穿设在相邻两节管廊节段的张拉孔内的钢绞线和用于张拉所述钢绞线的张拉驱动，所述钢绞线内设置有光纤；张拉调节装置包括用于采集和解调张拉数据的采集器和与所述采集器通信连接的光纤传感器，所述光纤传感器用于检测所述光纤的波长变化，且所述光纤传感器设置在所述钢绞线内；控制装置与所述张拉调节装置和所述张拉驱动通信连接。通过在钢绞线内设置光纤，通过光纤传感器和采集器对光纤应变进行实时监测，可以实现对钢绞线的张拉应力实时调控，确保各个张拉点的张拉力均大于预设值，保证张拉质量，提高管廊节段的密封性，能够保障管廊的正常运维。
