| 简介 |
The present invention relates to a device and a method for re-tensioning a steel strand, and more specifically, to a permanent ground anchor which is fixed to the ground by using a high strength tension member and stabilized on an excavation wall or a surface of a slope by applying a weight to the tension member. The method for re-tensioning a steel strand easily re-tensions the steel strand while checking a tension force in real time without using a conventional hydraulic means.(1) Initial tension state(2) Assemble a measurement device(3) Assemble a re-tensioning rotary body(4) Check rotation and tensile force of the re-tensioning rotary body(5) Insert a steel plate(6) Complete processing steel plate insertion and release re-tensioning mechanism(7) Fill grease after installing a protective cap(AA) Raise a fixing part and a steel strandCOPYRIGHT KIPO 2016 |
