摘要

PURPOSE: To hold a ground anchor in a proper position, to be suitable for a new material ground anchor having excellent corrosion resistance and improve corrosion resistance of a spacer to hold a tensile material in a drilled hole. ;CONSTITUTION: A spacer 18 is formed such that a disc part 19 having a plurality of circular holes 19a and notches 19b in which tensile material 3 are respectively inserted and a plurality of protrusion parts 20 protruded from the outer periphery of the disc part 19 are integrally formed by using synthetic resin, such as rigid plastic. Thus, since the disc part and the protrusion parts are integrally formed by using synthetic resin, the tensile materials can be held in a correct position for a long period. Further, the number of parts and the number of processing works can be reduced.;COPYRIGHT: (C)1993,JPO&Japio
