Announcing a new sister site to GeoPrac, GeotechSearch.com – a geotechnical search engine! This search engine is powered by Google’s Custom Search with it’s own clean interface. Search queries only return results from sites that are hand picked by myself and other members of GeoPrac.net. So you don’t have to sift through results that aren’t relevant to geotechnical engineering, geological engineering and related disciplines.
The source of sites included in the GeotechSearch search engine come from the GeoLinks section of this site. Any GeoPrac.net member can contribute links (subject to approval) and they will then be included in the search engine results within a few days. So if you’re not a member, why not join GeoPrac.net? And then contribute a link to the GeoLinks section. I’m incredibly excited to really start tapping into the capabilities of GeoPrac as a true online COMMUNITY of "geo" practitioners for the benefit of all in our profession…the possibilities are endless!
Challenging WV Transmission Station Pipeline Job on 58-Degree Slope Uses TerraThane by U.S. Company, NCFI Polyurethanes
MOUNT AIRY, NC—A recent pipeline job at Dominion Resource’s extraction/fractionation plant in Pine Grove, WV presented some pretty hairy challenges. First the pipeline was to be laid on a 58-degree hillside. Trucks, excavators, and other equipment had to be wenched up the slope and held in place by cables attached to heavy equipment. Secondly, it was the rainy season, so erosion of the freshly turned earth was a major concern. [Editor] Click through for the rest of the press release. [/Editor]
Grain Bin Settlement Problems Common to Concrete Foundations Solved with NCFI’s Geotechnical Polyurethane Foam Technology
MOUNT AIRY, NC—Soil consolidation and settlement happens. It’s a fact of farm life. Secondary consolidation slowly forces water out of the spaces between soil particles. As this happens, soil particles move close together and settling occurs. Floors drop and become uneven. Newer grain silos and bins are using concrete floors instead of metal, and as secondary consolidation occurs beneath them, depressed or “settled” areas, form within the bin. Grain accumulates in the depressed areas, but cannot be retrieved by the bin sweeper. In fact, the sweeper, a kind of auger that transports grain up from the floor, can become damaged from prolonged exposure to the uneven floor.
This is exactly what Kirk Roberts of CJGeo, a Williamsburg, Virginia-based commercial foundation repair and geotechnical contractor, found when he got the job to repair the foundation of a massive 106-foot diameter grain bin at a poultry processing facility on the Eastern Shore of Maryland. “Once they removed the hundreds of thousands of bushels of grain, we found the floor had dropped some three inches in one section of the bin leaving a large pocket of grain out of reach of the bin sweeper.”
