Walls anchoring

An anchor is a tension support, which limits movement from subsequent excavation by providing a pre-loaded condition to the supported ground. Tensile load is transmitted by a steel tendon made of individual strands or bars. The tendon is bonded to competent rock or soil by cement grout.

• Applications for Anchors
  • retaining walls
  • temporary excavation support (replace struts or rakers for improved working space)
  • landslide control
  • rock cuts
  • dam stabilization
  
  
  
• Advances of Anchors
  • Using comprehensive corrosion protection systems, rock and soil anchors achieve reliability, longevity, and economy.
  • In both temporary and permanent retaining applications, ground anchor systems have proven to be a viable economic alternativeto conventional retaining walls --especially in instances where excavation is undesirable.
  • Stressing tests every anchor to greater than design load
  • High capacities in rocks and soils
  • Can be permanent if installed with appropriate corrosion protection
  • Can be installed at any inclination through all types of overburden and rock
  • Compatible with the construction of all types of wall systems including sheet piles, soldier piles and laggings, drilled shafts, soil mixed walls and diaphragm walls.
  
  
  
• Anchor Installation
  1.Drill hole
  2.Set tendon
  3.Grout via Tremie Tube ( may be before tendon)
  4.After grout cures; stress, test, and lock-off anchor
