The causes of defect generation mainly include the following aspects: 1) The ballastless track is extruded, impacted and the like in the high-speed heavy-load running process of the train, so that various defects such as incompact, cracks or hollows can occur in the ballastless track, and a damaged layer or a honeycomb hemp layer is formed outside the ballastless track; 2) The ballastless track has defects due to possible problems of construction process and construction experience in the earlier stage of manufacture; 3) Defects are also caused by natural disasters such as erosion of rain and snow, environmental temperature change and the like. The existence of the defects seriously affects the bearing capacity and durability of the ballastless track, the ballastless track structure can be disabled, the stability and smoothness of the ballastless track and the off-line structure of the high-speed railway can not be ensured, and the stability and smoothness are just important preconditions for ensuring the rapid and safe operation of the high-speed railway. Therefore, the detection and the timely overhaul of the rail defects are very important to ensure the stable running of the train and the life and property safety of people.
The ballastless track box girder defect detection is an important detection part for ballastless track defect detection.
