Pipelines & Conveyors

Overland conveyors and trestle towers often require solutions to accommodate significant uplift loads and overturning moments. Foundations for conveyors align themselves perfectly to screwpiles because there are generally large quantities required. The speed in which screwpiles can be installed in this situation promotes their cost-effectiveness.  

A variety of connection methods to modules and trestles are available. Options include direct weld connections through to small concrete pile caps.

Conventional methods of anchoring pipeline structures to the ground are not only costly and slow ,but carry inherent problems for the future, applying enormous pressure on ongoing maintenance budgets. These problems include moisture entrapment between the concrete overhead cap anchor and the pipeline causing:

  • The pipeline to corrode in a relatively short period.
  • The steel reinforcing locking bars within the overhead corrode exploding the concrete due to extreme environmental temperature fluctuations

Other problems such as corrosive and flood prone environments in salt flats and flood plains, present further problems for conventional methods of anchoring. Steel frames are prone to corrosion at the intersection with concrete, requiring entire foundation and structure replacement. Flowing volumes of water undermine conventional foundations causing subsequent pipeline damage.

Screwpiling offers a one-machine and procedural operation of anchor foundation installation. Pre-drilling can be carried out with the same machine should hard soil conditions be encountered. The use of screwpiling resulted in a general cost saving of 250% compared to conventional anchor methods. Construction productivity was increased by a massive 1200%. Future related corrosion maintenance budgets virtually eliminated over the next 75 years.
