Light Weight Deflectomete

It is used for the deflection value of layer subgrade under dynamic load, so as to evaluate the bearing capacity and deformation of subgrade. It is applicable to the monitoring and inspection of foundation construction quality of railways, highways, airports, urban transportation, ports, wharves and industrial and civil buildings under dynamic loads, especially for the inspection of narrow sections of the site, such as the inspection of transition sections and shoulders of roads and bridges (culverts), existing line foundations, etc. The instrument simulates the impact effect on the subgrade when the train is running at high speed, and can better reflect the actual stress of the subgrade soil than the static load test. It can quickly measure the dynamic deformation modulus EVD value.
