| description | The utility model provides a pre-embedded fiber melting and collecting device, and relates to the technical field of pre-embedded installation of fiber grating sensors. In order to solve the problems that an optical fiber connector needs to bear high-frequency vibration impact during cement feeding in the pre-embedding process, extrusion force in the cement pouring process, seepage damage of cement mortar and secondary expansion in the cement curing process, the adopted technical scheme is that the optical fiber connector comprises a base and an optical fiber, an upper cover is arranged at the transparent end of the base, a plurality of fiber coiling rods are arranged in the base, a plurality of through holes communicated with the inside are further formed in the side wall of the base, and the optical fibers penetrate through the through holes to be connected with the fiber coiling rods. The device is suitable for assisting in completing pre-embedded long-term measurement of variations such as strain, displac |
