Rock Bolting

ROCK BOLT INSTALLATION

RIX have many years experience stabilising boulders and or wedges of fracturing rock by installing rockbolts.

 

 Lower keystone rocks which are supporting upper slabs have been rockbolted to stabilise this cliff faces.   A strategy of rockbolting is suited to locations with short working hours like between the traffic peak hour times in road corridors.

 
Rockbolts are typically rigid bars inserted into predrilled holes through a geologically defective area. The bolts are typically secured into stable ground beneath the fault using a cement or chemical grout and or a mechanical fastener.

Rock bolts of high tensile steel and or glass reinforced plastic can be ideal solutions for the stabilisation of cliff faces and steep rocky slopes.

A rock bolt can be passive or active.
 
Passive Rockbolts - have no pre-stress load applied, and will only take a load if movement occurs.

Active Rockbolts - are pre-stressed prior to the curing of the grout and or via a mechanical fastener.
 
 
 
 
RIX’s previous projects normally entail restricted access. Successfully completed projects range from:
  • remote locations requiring helicopter access,
  • mines,
  • rail cuttings to
  • inner city residential developments.
