[0002] Roadbed refers to a strip structure built as the foundation of the road surface according to the route location and certain technical requirements. It is the foundation of railways and highways. The roadbed is a linear structure built with soil or stone. The roadbed is built under good geological, hydrological and climatic conditions. In terms of materials, the roadbed can be divided into three types: soil roadbed, stone roadbed, and soil-stone roadbed.

[0003] During the inspection of the roadbed plane, the roadbed and the inspection road surface will be inspected. The traditional method is spraying, and the improved method is wedging the positioning nails.
