APPARATUS FOR MEASURING THE LAST QUANTITY OF SINKING

摘要

The present invention relates to a final settlement measuring device for confirming the restriction of the allowable frictional force in the piloting of concrete piles (precast concrete) to reinforce the unstable designation. More specifically, the lower end has a wedge shape. Forming a rectangular frame, one side hinged at the top and bottom, the other side formed a hook to open and close.Separate support rods were installed between the upper and lower end rods of the front, and the support of the pencil holder with the ring protruding outward in the center of the support rod It is attached to the hinge of the support plate, and the coil spring is installed from the support plate to the pencil holder so that the pencil holder rotates and returns, marking the concrete pile to check the settlement amount. In rudder work to type C), concrete The square of the upper end (2) (2 ') and the lower bar (3) (3') welded to the fixed bar (1) (1 ') of the wedge-shaped around the pile (C) type Form the frame (H), but the opening portion (M) is provided with hinges (4) (4 ') on the upper and lower sides and hooks (5) on the other side to open and close, and between the upper and lower end rods (2) (3) on one side Install a separate support rod (6) on the back and the pencil holder (7) with a ring (7 ') protruding outward in the center of the support rod 6 is coupled to the hinge of the support plate (8) and the pencil holder ( 7) the final settlement amount measuring device, characterized in that the pencil holder (7) is rotated and returned by installing the coil spring (9)
