STRUCTURE OF ANNULAR ROD AND BUNDLED TUBE-SHAPED SOIL NAILS FOR INCREASING THE REUTILIZATION OF THE WASTE MATERIALS BY USING PET(POLYETHYLENE TEREPHTHALATE) AS A STIFFENER FOR THE ANNULAR ROD-SHAPED SOIL NAIL AND BOTH ENDS OF A BUNDLED TUBE

摘要

PURPOSE: A structure of annular rod and bundled tube-shaped soil nails is provided to reuse PET plastic bottles as a stiffener for an annular rod-shaped PET soil nail and both ends of a bundle string and to prevent excessive displacement by attaching a settling cone to the front end of a soil nailing. CONSTITUTION: In a structure of an annular rod-shaped soil nail and a bundled tube-shaped soil nail(30), both ends of the annular rod-shaped soil nail made from PET have threads and one side of the member is combined in a screw groove of a settling cone(20). A bundled tube(32) is thermally welded to each other by drawing in plural nail strings formed by binding nail strands. Both ends of the bundled tube are settled and thermally welded with a sleeve unit(33) that is a PET lump. The sleeve unit has threads and one side of the sleeve unit is combined to the screw groove of the settling cone.
