Experimental Device for Drawing Supporting Force of Underground Anchor

摘要

An experimental device for testing the pullout resistance of an earth anchor is provided to obtain more accurate test result by changing the position of pullout force applied to the anchor. An experimental device(100) for pullout resistance of an earth anchor includes a housing(10), a driving unit(20), an angle adjusting unit(40), and a load cell(60). The housing has an opened upper part, and has an anchor(2) inside. The driving unit is installed at the upper part of the housing, and pulls a rope(4) connected to the anchor. The angle adjusting unit is installed in the housing to face the driving unit, and changes the angle between the other end of the rope connected to the anchor and the ground. The rope connecting the driving unit and the anchor passes through the angle adjusting unit. The load cell measures the load of the rope when the rope is pulled by the driving unit.
