Light Weight Deflectometer
Light Weight Deflectometer is used to detect the deflection value of the sub-grade under dynamic load, so as to evaluate the bearing capacity and deformation of the sub-grade.
It is suitable for the monitoring and testing of the foundation construction quality of railways, highways, airports, urban traffic, ports, docks, and industrial and civil buildings under dynamic loads.
It is especially suitable for testing narrow sections of the site, such as road and bridge transition sections, existing line sub-grades, etc.
The instrument simulates the impact effect of the train on the roadbed when the train is running at high speed.
Compared with the static load test, it can better reflect the actual stress of the roadbed.
It can quickly measure the value of the dynamic deformation modulus.
Test
Test and display three settlement values, automatically calculate the average settlement value Si and dynamic deformation modulus value.
Storage
Store the three subsidence values, average subsidence value and value of each test sequence.
