PURPOSE: A displacement measurement device for a bidirectional pile loading test is provided to automatically measure the displacement of a pile using a weight having a magnetic member. CONSTITUTION: A displacement measurement device for a bidirectional pile loading test comprises a cylinder, white pipes(20), weights(50), and control boxes(60). The cylinder is pressed to widen the gap between upper and lower plates installed inside a pile. The white pipes are fixed to the upper and lower plates in the longitudinal direction of the pile. The weights are installed inside the white pipes and are vertically moved by electric wires(40). Magnetic members are installed on the bottom end of the weights. The control boxes have winches and displacement meters. The displacement meters measure the displacement of the electric wires. |
