Earth retention is simply a method to shore, or stabilize soil/rock that has been removed to form an excavation, cut, or slope. Temporary or permanent structural retaining walls use soldier piles with wood lagging, sheet piles, or structural diaphragm walls to resist lateral earth pressures from retained soil. CHANCE® helical tieback anchors are pre-manufactured steel anchor elements consisting of a central steel shaft and one or more helical shaped bearing plates. CHANCE helical tieback anchors provide additional lateral support for many retaining wall designs. A helical tieback anchor is installed by rotating, or screwing it into the ground. Each helical bearing plate is formed into a screw thread with a uniform defined pitch. The helical tieback anchor is installed into the ground until the helical plates are located in load bearing soil. The tieback anchor is then attached to the wall face.
Soil nail walls are another type of earth retention system. They can provide temporary or permanent stabilization of cuts and slopes. CHANCE® SOIL SCREWS® are pre-manufactured steel anchor elements consisting of a central steel shaft and several helical shaped bearing plates spaced continuously along the shaft. CHANCE SOIL SCREWS® are installed by rotating, or screwing into the ground until the required nail length is achieved. Each helical bearing plate is formed into a screw thread with a uniform defined pitch. The SOIL SCREW is then attached to the wall face.
The CHANCE® SOIL SCREW® Retention Wall System reinforces the earth to construct gravity walls.
In this “soil nail” application, a CHANCE screw anchor acts in a bearing mode compared to grouted anchor, which relies on friction. This gives the SOIL SCREW Retention Wall System economic advantages. Bearing plates are spaced along the entire length of SOIL SCREW anchors. They are ready for immediate loading as soon as installed.
Backhoes and skid-steer loaders can quickly rotate SOIL SCREW anchors into place. Anchor size and grid spacing are designed to local soil conditions and load requirements. A reinforced-shotcrete veneer often is applied to the wall face.
