GTJ-Ev2-W Plate bearing test set is used to measure the settlement value of Subgrade under static load, so as to evaluate the bearing capacity and deformation of subgrade. It is suitable for monitoring and monitoring the construction quality of railway, highway, airport, urban traffic, port, wharf and industrial and civil buildings subjected to static load.
After the first loading and unloading of the ground by the circular bearing plate and loading device, the second loading is carried out. The values of deformation modulus Ev2 and Ev2/Ev1 are calculated by the measured stress_under the bearing plate and the corresponding central settlement value S of the bearing plate.
- The first data processing method of mobile APP in China has realized wireless data acquisition and transmission, and
provided a cloud transmission port dockable engineering detection and management system to provide reliable data sources
for real-time data acquisition, on line data analysis and large data management.
- lmported sensors and parts of components are used to achieve high test accuracy.
- lmported cylinders and manual pumps are adopted, with outstanding performance of pressure control and voltage
- The displacement acquisition device adopts heavy profile and three-point support design, which has strong seismic and
windproof capability and ensures accurate data.
- Automatically calculate Ev1, Ev2 and Ev2/Ev1 values and display curves;
- Wireless Bluetooth micro printer can print directly on the spot to ensure the accuracy and objectivity of the test results.
This GTJ-Ev2 static modulus of deformation tester is to measure the subsidence value of subgrade in static load to get the bearing
capacity and deformation of subgrade. This static modulus of deformation tester is suitable for the quality control of subgrade in the areas such as railway, road, airport, urban road, seaport, wharf, industrial and civil architecture.
Working principle of modulus of deformation tester:
- loading via circle loading plate and clamping device and then release.
- re-load after the first release.
- calculate deformation modulus value Ev2 and value of the ratio of Ev2/Ev1 by the measured value lower stress σ and its relative subsidence value s in the center of loading plate.
