Key Features

  • The MP Bolt consists of a bar thread, specially designed expansion shell and drive nut.
  • The MP Bolt Expansion Shell has been designed to reduce the grout resistance upon bolt installation.
  • The MP Bolt provides immediate rock reinforcement through mechanical anchorage while the grout cures.
  • The MP Bolt bar is hot rolled with deformations that form a course left hand thread (10mm pitch) over its entire length.
  • Single pass bolt installation.
  • The thread bar form provides good load transfer properties.
  • Corrosion protection provided by full column grout.
  • Provides immediate support.
  • Drive nut ensures reliable setting of the Expansion Shell and provides a bolt tail for subsequent meshing.
  • Additional corrosion protection may be provided by hot dip galvanizing.

Mechanical Pre-Gouted MP Thread Bar Bolt - Notes

Notes

  • Only DSI rock bolt components should be used to enable the optimum performance of the bolt system to be obtained.

Mechanical Pre-Gouted MP Thread Bar Bolt - Installation Guide Lines

Installation Guide Lines

  • 35mm hole diameter are preferred.
  • The drilled hole length must be longer than the bolt by approximately 50mm.
  • Appropriate components are fitted to the bolt. The Expansion Shell is screwed onto the bolt until the bolt thread just protrudes through the Expansion Shell plug.
  • The hole is pregrouted by retracting the hose from the toe to the collar.
  • The bolt is inserted through the grout.
  • After placing the bolt in the hole to its full length, the bolt is rotated to set the expansion shell and apply tension.
