Product Description
GTJ-Evd Dynamic Deformation Modulus Tester (Handheld Drop Weight Deflectometer)
Usage overview
The GTJ-Evd type dynamic deformation modulus tester (hand-held drop weight deflection instrument) is used to determine the deflection capacity of the subgrade under the dynamic load, thereby evaluating the bearing capacity and deformation of the subgrade. It is applicable to the monitoring and inspection of foundation construction quality of railways, highways, airports, urban traffic, ports, terminals and industrial and civil buildings subjected to dynamic loads. It is especially suitable for the detection of narrow sections of the site, such as the transition of roads and bridges (culverts) and the detection of shoulders. , both line base and so on. It can quickly measure the dynamic deformation modulus Evd value.
Applicable standard
"Earth Test Method for Railway Engineering" (TB10102-2010) "Evd Plate Load Test".
Features
※ Imported sensors and some components are used for high test accuracy.
※ LCD display in English and Chinese, there are corresponding Chinese and English prompts under different interfaces; with backlight, it has better visibility in various environments.
※ The operation is simple, the test speed is fast, and the detection takes only 35 seconds.
※ The Evd value is automatically calculated and the curve is displayed, which is accurate and intuitive.
※ Handheld main unit with Bluetooth micro-printer, direct printing on site to ensure accurate and objective test results.
※ USB transmission interface, easy to connect with the computer.
※ This instrument simulates the impact of the train on the subgrade when driving at high speed. Compared with the static load test, it can reflect the actual stress of the subgrade soil.
※ Non-nuclear radiation and exhaust gas pollution, safe and environmentally friendly.
