Cold casting anchorage device inhaul cable containing fiber bragg grating strain and installation method
The invention belongs to the technical field of bridge inhaul cable manufacturing and monitoring, and particularly relates to a chilled cast anchorage device inhaul cable containing fiber bragg grating strain and an installation method.The chilled cast anchorage device inhaul cable comprises an anchor head structure, one end of the anchor head structure is fixedly connected with an extension structure, and the end, away from the anchor head structure, of the extension structure is fixedly connected with a cable body; the inner side of the anchor head structure is fixedly connected with a plurality of steel strands, and the steel strands sequentially penetrate through the anchor head structure and the extension structure and are fixedly connected with one end of the cable body; and a spot welding high-temperature grating sensor is fixedly connected to the part of the side surface, located on the extension structure, of one steel strand. By means of the structures, the cold casting anchorage device inhaul cable containing the fiber bragg grating strain and the installation method can solve the creep deformation phenomenon in the sensor installation process, avoid sensor damage, improve the inhaul cable force detection precision and feed back the cable force condition in real time.
本发明属桥梁拉索制造及监控监测技术领域,尤其涉及一种含有光纤光栅应变的冷铸锚具拉索及安装方法,包括:锚头结构,所述锚头结构一端固定连接有延长结构,所述延长结构远离所述锚头结构的一端固定连接有索体,所述锚头结构内侧固定连接有若干个钢绞线,所述钢绞线依次穿过所述锚头结构、延长结构并与所述索体一端固定连接;其中一个所述钢绞线位于所述延长结构的部分侧面上固定连接有点焊高温光栅传感器。利用这些结构,实现了一种能够解决安装传感器时的蠕变现象,避免传感器损坏,提高拉索索力检测的精度,并且能够实时反馈索力情况的一种含有光纤光栅应变的冷铸锚具拉索及安装方法。
