For larger diameter shafts through unstable soils, the use of interlocking hard / soft CFA (continuous flight auger) piles is a highly cost effective method of shaft sinking. Alpine’s RockWheel rock & concrete grinders are often an important tool in these…
Alpine’s partnership with researchers at the Pennsylvania State University continues into 2014 as we continue to improve our soil mixer designs.
Using numerical modeling and particle tracing, the research team at PSU has simulated the complex interaction between fluid-solid…
Caisson walls are composed of vertically drilled, intersecting reinforced concrete piles constructed for ground support during excavation and construction activities, especially in urban areas where work is being done close to existing structures.
The resulting vertical face is a series of…
Alpine’s partnership with researchers at the Pennsylvania State University continues into 2014 as we continue to improve our soil mixer designs. Using numerical modeling and particle tracing we’re simulating the complex interaction between fluid-solid mixtures and mixing tools in order…
