The Drawing above shows a section through a sheet pile wall with a grouted soil anchor in place.
The capacity of the anchors can vary from 60 kips to over 100 kips depending on the soil conditions and jobsite requirements. The free length is a bond free zone that is used to adjust the location of the anchor zone. The length of the bond zone is adjusted for the soil conditions and required anchor capacity.
DSI threadbars and hardware are used for the anchors. They are available with double corrosion protection for permanent installations.
The drawing above shows a section through a soil nail wall. Soil nail walls are used for excavation support and slope stabilization. The soil nail walls are used where overhead clearance is limited or when other site restrictions make construction of “ground up” conventional walls impossible or impractical.
H.B. Fleming has the computer assisted design capability to fit nail walls to most any jobsite or application.
Shown Below is the machine we use to install our grouted soil anchors and soil nails. The machine is an excavator with a 45’ long hollow stem auger mounted on it.
In the background is a sheetpile wall that is supported by a level of post tensioned anchors at the upper level. At the ground level, you can see several anchors that have been installed but not yet tensioned.
This picture shows how these deep excavations (up to 40’) can be made using our anchors.
Below is a picture of a major highway that is braced temporarily using sheetpile and grouted soil anchors. It is important to notice that the excavation is entirely clear of supports and bracing that are typically used to brace sheetpile walls. This single variable can eliminate construction joints on foundations, which can reduce cost and save time.
