This invention discloses a track slab fine-tuning device and method for CRTSⅢ type slab track. The device includes an upper frame, a lower frame, an attitude adjustment mechanism, a travel and steering device, a fine-tuning mechanism, and four sets of turning mechanism components. The attitude adjustment mechanism drives the lower frame to swing. The fine-tuning mechanism includes a forward and backward moving mechanism, an L-shaped mounting plate, a vertical moving mechanism, a vertical fastening mechanism, a turning plate, a swinging mechanism, a lateral moving mechanism, and a lateral fastening mechanism. The method includes the following steps: 1. Hoisting and moving the fine-tuning device; 2. Adjusting the attitude of the lower frame; 3. Adjusting the track slab by the fine-tuning mechanism acting on the fine-tuning claws; 4. Adjusting the pressure bar. This invention achieves the lifting and lateral movement adjustment of the track slab through the operation of the fine-tuning claws by the fine-tuning mechanism, enabling rapid adjustment of the track slab's elevation and centerline. Furthermore, the swinging nature of the fine-tuning mechanism allows for centering adjustments under different ultra-high working conditions.

This invention discloses a CRTSⅡ type slab track full life cycle performance evolution and remaining life prediction system, belonging to the field of intelligent operation and maintenance technology for rail transit infrastructure. The system consists of a five-layer architecture: a multi-source perception layer, an edge computing layer, a performance evolution model layer, a hybrid life prediction engine, and an intelligent decision-making layer. It pioneers a four-field coupled performance evolution model of temperature, humidity, dynamic load, and foundation settlement, and constructs a hybrid life prediction engine of LSTM-grey prediction-Weibull distribution to achieve quantitative description of the full life cycle performance degradation of the track slab, CA mortar layer, base plate, and interlayer interfaces, as well as accurate prediction of remaining life. The system can automatically output maintenance level, maintenance timing, and special plans, completing the upgrade from post-maintenance to predictive maintenance. The invention has a relative error of ≤8.3% in remaining life prediction, ≤5.6% in performance evolution prediction, and ≤1.2s in early warning response. It is suitable for all scenarios including roadbeds, bridges, tunnels, high-altitude and high-temperature and high-humidity environments. It can improve operation and maintenance efficiency by more than 60% and reduce the total life cycle maintenance cost by 35%. It is applicable to intelligent operation and maintenance and safety assurance of CRTSⅡ type slab track for high-speed railways.
