The load cell (jacks) is a specialized pressure cell that is attached to the reinforcement cage, and placed at the bottom or in the lower part of the drilled shaft. It has a hydraulic line extending from the cell to the top. After placement of the reinforcement cage, the hole is filled with concrete.Read More...
The rebar strain meters are used for the purpose of measuring concrete strains due to imposed load. With sufficient rebar strain meters, axial load distribution along the drilled shaft can be determined. The skin friction of different soil layers and end bearing capacity can be determined, too.Read More...
The load cell is designed to weld with the rebar cage, and then lowered into the hole. When the concrete is poured, the load cell is embedded in the drilled shaft.
During bi-directional static load test, the displacement of the upper and lower plate of the load cell should be recorded. The Displacement transfer apparatus(DTA) are designed to transfer these data to the top of the drilled shaft for measuring.Read More...
Data collection and load control system (DCLC) is designed to collect data and apply load automatically during the load test.
DCLC records the load applied at the load cell, the displacement of upper and lower plate of the load cell, the displacement of the pile top, and the strains of rebar strain meters. Based on the data collected, related curves such as Q-S, S-lgt, S-lgQ et al are real-time displayed.Read More...
