Multistrand Anchors

System Description

DSI's Multistrand Rock and Soil Anchor System is based on the proven prestressing technology of the DYWIDAG Post-Tensioning System and decades of experiences in anchor technology. The system is extremely versatile and can be adapted to meet almost any project requirement.

Large Forces

Although there is no theoretical limit to the capacity of a multistrand anchor, practical considerations such as drill hole size and the availability of material handling equipment limit the size of an anchor to 61-0.6" (15.2 mm) dia. strands. Larger anchors can be manufactured ,but the practicality and economics of their use should be thoroughly evaluated before they are incorporated into a design. Very large anchors should be avoided in order to assure a satisfactory force redistribution in case of an anchor failure.

Long Length

No theoretical length limit exists; however, practical drilling and material handling considerations must be considered. For shop fabrication, the practical limit is dictated by total anchor weight.

Small Bending Radius
Strand anchors can easily be coiled to fit on a flat bed truck and are well suited for installation where work space is limited.


Corrosion Protection Options

A wide variety of corrosion protection options are available to choose from, depending on the expected length of service and the aggressiveness of the environment.

 

  • Single Corrosion Protection SCP (Type A)
  • Double Corrosion Protection DCP (Type B)
  • Double Corrosion Protection DCP (Type C)
  • Double Corrosion Protection DCP (Type D)
  • Double Corrosion Protection DCP (Type E)
