Anchor Pull Testing

Anchor Pull Testing

At Applied Technical Services, we frequently perform anchor pull tests to be used as a quality control. When anchoring an item, the rock bolt should be mounted in the same means and method and in the same surface it is envision or projected to use in a construction. To test the anchors or to perform an anchor pull test, the bolt is pulled with a hydraulic manifold and the displacement of the head of the bolt is measured concurrently. Hydraulic pressure is applied to the bolt until the material or the anchor bolt fails.

What is Anchor Pull Testing?

Our experts at ATS are the best when in it comes to Anchor Pull Testing. The main purpose or objective for the use of this test is to measure the performance of the anchor, and not the rock bolt or material performance. While testing, the anchor bolt must be long enough to ascertain that the failure transpires or happens in the anchor system and not by the testing equipment used applying force on the rock material on mass. Ideally, the anchor bolt should fail by shearing at the bond of the rock or material and the anchor. Our team can travel to many sites that others can’t, and it is Applied Technical Services committed to provide the best service to our clients as well as unblemished and precise assessment results in agreement with standard specifications.

Anchor pull tests ought to be performed in all types of rocks in which the construction anchor bolts will be installed to. When rock is bedded, schistose or anisotropic, the tests ought to be conducted in several orientations in relation to the anisotropy (acquiring different values when measured in different directions), including those at which the construction bolt may be installed..
