Rock Bolt Pull Out Test Apparatus VSLIC-C250

short info

The objective of the test method is to measure the working and ultimate capacities of rock bolt anchors.

The system comprises of a central hole jack, hand pump with load gauge, directional control valve (only for central hole jacks above the capacity of 500kN), flexible pipes, truss high tensile test rod with coupling.

In general the pull out force is indicated on load gauge, however a load cell can be used for the measuring of pull out load. Arrangement is provided for fixing dial gauge for estimating deflection against the load.

Standard

BIS – 11309, ASTM D4435, ISRM.

Specification

The Pullout Test apparatus supplied by Vertex is a leading manufacturer is used for the purpose of measuring the strength of an installed rockbolt under the field conditions.

The strength of the rockbolt is measured with the aid of a pull test, within which the head displacement of the bolt is measured as a function of applied bolt for giving a curve to load displacement. The test is normally done for the purpose of assessing the performance of the Rockbolt anchor that results from the quality of material to manufacture Rockbolt.

The equipment comes equipped with a hydraulic pump which is operated manually and is connected to the hydraulic jack. The hydraulic jack features test rod of higher strength in respect to the Rockbolt test. Similarly, the anchor goes through the testing procedure through measuring of the load till the time entire displacement is recorded or the bolt yield gets fractured. The displacement readings are taken in increasing number which is about upto. 5 kN load or 5 mm, or whichever happens earlier.
