AN APPARATUS FOR TESTING THE UPLIFT CAPACITY OF FOUNDATIONS OF TRANSMISSION LINE TOWERS

摘要

An apparatus for testing the uplift capacity range foundation of a transmission line lower comprising a loading frame mounted on rigid supports firmly embedded in the ground; pulling means provided with a calibrated load cell for measuring the pull applied, said pulling means being mounted on the frame for exerting a pull on an embedded anchor stub located under the frame, the said means being provided with a trunnion block to permit the (rule to act along the axis of the stub, at least one determination gauge provided for the pulling means for determining the displacement of the stub: a road welded to the stub and fixed to the said means, whereby the pull exerted by the said means and transmitted to the rod tends to hit the stub from the ground, while the pull exerted and the displacement of the stub are simultaneously determined by the load cell and the deformation gauge.
