一．Product Background Technology
Track plate refers to a new type of underrail component with plate structure, which is used to support and fix the rail, and distributes the load transmitted by the train through the rail to the underplate base. Track plate away from the seam and subgrade filling, train load, construction control, and is closely related to the factors such as the operating environment and long-term exposure to the natural environment, is impacted by the train load, temperature cycle and water enroach on, mortar layer between the track plate and easy generation from the seam, and huge load for a long time can lead to track plate and the base board and gradual degradation, lead to the driving stability is affected, Therefore, it is very important to comprehensively detect and assess the damage of rail system and carry out effective maintenance work.
1.Test project

Test objects: CRTS ⅰ type plate, CRTS ⅱ type plate, CRTS ⅲ type plate, turnout plate, base plate, wide and narrow joints and other diseases;

Test contents: track plate, base plate damage and internal defects, track plate seam detection and other items.

2.Product features

The range and degree of rail plate disease and defect are determined by impact echo method and travel time imaging principle. It provides technical support for reinforcement maintenance and maintenance of track plate.
