ANCHOR CONSTRUCTION METHOD OR ROCK BOLT CONSTRUCTION METHOD USING CARBON FIBER PLATE IN TENDON

摘要

PROBLEM TO BE SOLVED: To provide a method for freely changing the length of an anchor according to a ground condition, easily machining a tendon on a site, and facilitating the transporting/carrying-in of the anchor.;SOLUTION: In an anchor construction method or a rock bolt construction method by using carbon fiber plates in the tendon, the tendon is made to have corrosion resistance by a carbon fiber material of high tensile strength, and made by using one or a plurality of plates made of carbon fibers. The tendon is cut and joined in the middle portion, and adjusted to be length suitable for use by connecting the tendons of required length when used. The tendon of the plate made of the carbon fiber material of high tensile strength in an anchor body portion or an anchor head portion is cut off at the middle portion, and adjusted to be length suitable for use by connecting the tendons of the required length when used. Therefore, transporting/carrying-in and assembling are facilitated.;COPYRIGHT: (C)2012,JPO&INPIT
