PURPOSE: A pile displacement sensing device is provided to accurately construct a continuous pile by sensing and adjusting the perpendicularity of the pile while driving the pile. CONSTITUTION: A pile displacement sensing device comprises a hydraulic rotating support(30), upper and lower part sensing stands(40a,40b,50a,50b), upper and lower part supports(45a,45b,55a,55b), a hydraulic jig(60), front and rear perpendicularity sensors(42a,42b,52a,52b), and left and right perpendicularity sensors(43a,43b,53a,53b), and a control unit(90). The hydraulic rotating support supports and horizontally rotates a body part. The upper and lower part sensing stands support a pile by hydraulically catching the pile from the left and right sides and sense the right and left perpendicularity of the pile. The upper and lower part supports support the pile by catching the pile from the front and rear sides. The hydraulic jig compress the inner wing of a pair of rails for fixing a carriage stand(10). The front and rear perpendicularity sensors sense the front and rear perpendicularity of the pile. The left and right perpendicularity sensors sense the left and right perpendicularity of the pile. The control unit controls a communications unit(91) to transmit the front and rear, left and right perpendicularity to an administrator terminal. |
