STUDY ON THE TENSION METHOD OF ANCHOR ROD AFTER GROUTING
As a common form of support,anchor cable support is often used in the construction of foundation pit and slope.In order to ensure the safety of construction,it is necessary to ensure that the pullout resistance of anchor cable conforms to the design regulations,in order to determine the magnitude of anchor cable load,it is necessary to carry out pull-out test of anchor rod.The implementation of pull-out load test of bolt is often affected by the length of bolt leakage.When the length of the anchor is enough,it can be stretched directly,but there is no suitable method for anchoring when the length of the anchor is not enough or the anchor has been sealed.In order to solve this problem,this paper puts forward the method of adopting new type round-table anchor to lock,using wedge-shaped device to clamp anchor when stretching,and using hollow jack to stretch,and probes into this difficult problem.
