This approach minimizes start-up time and can be faster and … Soil Nails. Rental, sale & buyback of sheet piles and H-beams. The technique involves the insertion of relatively slender reinforcing elements into the slope – often general purpose reinforcing bars (rebar) although proprietary solid or hollow-system bars are … GeoStabilization utilizes the most advanced technology available for landslide repair. This wall type is also appropriate for cut applications and can be constructed either as temporary or permanent. This report is a summary of the activities of Demonstration Project 103. We offer an array of finishes for permanent walls including sculpting and staining to closely resemble almost any natural or manufactured surface. Oversized holes of 4” to 10” in diameter are drilled and the centralized soil nail component is placed. Each soil nail consists of a reinforcing bar that is generally made of steel (with full corrosion protection for permanent works) although self-drilling hollow-bar soil nails can be installed where soil conditions allow. TxDOT’s first soil nail wall was built in 1988 for a Texas Turn Around. Soil nail walls are perhaps most often used in relation to the stabilizing slopes and landslides. accepted by the Bureau of Structures prior to start of the construction. The job was essentially to install soil nails and a temporary shotcrete facing to allow Flatiron to finish it off with a cast-in-place concrete wall. The use of sub horizontal ground anchors with sheet pile or soldier beam shoring permits taller walls and deeper excavations than are possible with cantilever type construction–up to 35 feet or so depending on soil properties versus 15 feet for cantilever construction.
