CLOTHING MEMBER WATERPROOF STRUCTURE OF THE REMOVABLE TENSION TYPE GROUND ANCHOR

摘要

PURPOSE: A waterproof structure of a tendon-removal-type ground anchor is provided to prevent the collapse or the contraction of a PE hose due to grout pressure and to reliably waterproof between the PE hose and a wedge block by the preventing of ring separation. CONSTITUTION: A waterproof structure of a tendon-removal-type ground anchor comprises an insert member(4), a ring member(6) and a waterproof cap(8). The insert member is inserted into the front inner surface of a PE hose(h) to prevent the PE hose from becoming contracted by grout pressure. The PE hose wraps tendon. The ring member is inserted into the front outer surface of the PE hose to prevent the insert member from becoming separated. The ring member makes tight contact with a watertight material, which is installed on a wedge block. The waterproof cap is installed on the back end of the PE hose and blocks the water from flowing into the PE hose.
