Main feature
Holding a falling weight deflection instrument is used to measure deflection value of the subgrade under dynamic load, to assess the subgrade bearing capacity and deformation. Applies to the dynamic load of railway, highway, airport, urban transportation, ports, docks, and industrial and civil building foundation construction quality control testing, especially suitable for narrow area detection, such as road and bridge (han) transition section and shoulder detection, existing roadbed, etc..
