Home >> Rock Anchors

Anchors counteract lateral forces and overturning for dams and critical structures; they are also most commonly used to provide excavation support. Anchors consist of holes that are drilled vertical (for uplift support) or at angles for lateral support and filled with a cement grout. After curing takes place they are post tensioned.

Applications include:

  • Earth Retention Systems
  • Post Tensioning Dams
  • Seismic Stabilization

Anchors provide a cost effective bracing system for all soil conditions. Additional advantages include:

  • Final strength of the stabilized soil can be predetermined.
  • Attainable large loads.
  • Installation in limited access areas and complex drilling conditions.

Rock anchors are also frequently utilized for lateral support of slurry diaphragm. Since the rock anchors provide intermediate points of support at one or more levels, they reduce bending moments and consequently reduce the need for thicker walls, reinforcement, and depth-of-toe requirements. Anchors eliminate the need for internal steel bracing and strutting within the excavation and leave it free of obstructions which reduce excavation costs and speeds up construction. This aspect can be particularly valuable in congested urban locations with limited surrounding space for equipment and materials. Anchors are used in soils or in rock and may be either permanent or temporary.

Sinodrills' self drilling anchors can be installed as rock anchors, which performs drilling, anchoring and grouting in a single operation, no need to remove and insert casing tube, fastly save time and money.
