DEVICE SYSTEM AND METHOD FOR DYNAMIC TESTING OF GROUND SUPPORT BOLTS ANCHOR BOLTS OR ROCK BOLTS |
摘要 |
A connector, an associated dynamic testing system and method for testing rock bolts or rock anchors in situ. The connector is attached to a rock bolt/anchor and supports a hanging load via a shaft. The connector has a body of two halves retaining upper first and lower second connectors having respective curved surfaces. Each of the two halves has a curved inner surface allowing limited relative rotational movement of the first and second connectors relative to the two halves when a load is applied. A load cell and accelerometer register the load applied to the rock bolt/anchor through the connector and any resulting movement of the rock bolt/anchor. |
