Description

TECHNICAL FIELD

[0001] The application relates to the technical field of optical fiber communication, in particular to a long-distance distributed optical fiber laying device. BACKGROUND

[0002] The principle of the distributed optical fiber sensing system is to simultaneously use an optical fiber as a sensing sensitive element and a signal transmission medium, and to detect the changes of temperature and strain at different positions along the optical fiber by using advanced Otdr technology and Ofdr technology. The sensing optical cable equipped with metal reinforcing members has better tensile strength and durability than bare fibers, and is suitable for safety monitoring of large infrastructure, large concrete structural members and the like. For example, a distributed optical fiber protection device is proposed in CN 216954556 U for monitoring the stress state of a pile foundation in pile foundation construction; a monitoring system based on distributed optical fiber is proposed in CN 210862556 U for bridge deflection monitoring. In CN 221686693 U, the construction difficulty of the distributed optical fiber in the monitoring of the pi-shaped composite beam bridge is considered, and a set of installation auxiliary tools is proposed, but manual installation is still required. Compared with the traditional manual measurement methods such as steel stress meter, leveling measurement and micrometer, the distributed optical fiber has the advantages of fast measurement speed, high sensitivity and long measurement distance, but it still relies on manual installation and laying. The main problem faced by this method in the laying of optical fibers in long-distance structural members is that the stress reinforcement of the concrete structure is surrounded by stirrups, resulting in insufficient laying space, especially in the stirrup encryption area, making it difficult to lay the optical fiber on the stress reinforcement from the outside. Secondly, in the actual construction process of long-distance structural members, in order to ensure the overall stress performance, the members are often connected by welding, buckling and sleeve, which requires the optical fiber to be reserved at the connection for operation, and the optical fiber cannot be completely attached to the stress reinforcement, affecting the measurement of strain and temperature. In addition, compared with the segmented laying form of prefabricated members, the advantage of the through optical fiber is that it can reduce surface sticking, grooving and fusion splicing, reduce optical loss, and also reflect the deformation characteristics of the deformation joint of the connected members, but it also has the problems of high cost and difficulty in manual laying.
