Novel optical fiber intelligent steel bar planting device

Abstract

The invention provides a novel optical fiber intelligent steel bar planting device which comprises a cylindrical steel mesh reinforcement structure, an optical fiber sensor, an optical fiber demodulator and concrete. The novel optical fiber intelligent steel bar planting device is characterized in that the cylindrical steel mesh reinforcement structure has the effect of fixing the optical fiber sensor, the optical fiber sensor is used for monitoring the temperature and stress changes of a ballastless track plate and a base plate, the optical fiber demodulator is used for demodulating and analyzing data transmitted out of the optical fiber sensor, and the concrete is used for fixing the track plate and the base plate. When displacement happens between the track plate and the base plate, small displacement can happen at different positions of the intelligent steel bar planting device, at the moment, signals generated by the optical fiber sensor can change, and the temperature and stresschanges of the track plate and the base plate can be learned through the demodulator. By means of the novel optical fiber intelligent steel bar planting device, real-time monitoring can be realized, early warning is carried out in time, and accidents are reduced.

Description

technical field [0001] This patent relates to the technical field of high-speed railway ballastless track, specifically a new type of fiber optic intelligent bar planting device. Background technique [0002] At present, the bar planting technology of high-speed railway ballastless track is mainly steel anchoring construction. This method simply fixes the track slab and the foundation under the slab to prevent its relative sliding from affecting the stability of the train. In practice, it is found that when a high-speed train passes by, a certain force will be exerted on the track slab. This force will change the temperature of the track slab and the foundation under the slab, and make the force on the track slab and the foundation under the slab different. Rebar technology cannot monitor temperature changes and stress in real time. In order to ensure the stability of train operation and reduce the occurrence of safety accidents, a new type of intelligent rebar planting devi...

Problems solved by technology

In practice, it is found that when a high-speed train passes by, a certain force will be exerted on the track slab. This force will change the temperature of the track slab and the foundation under the slab, and make the force on the track slab and the foundation under the slab different. Reinforcement technology cannot monitor temperature changes and stress in real time. In order to ensure the stability of train operation and reduce the occurrence of safety accidents, a new type of intelligent rebar planting device is urgently needed to solve the above problems.
