Efficient Penetrators For Earth Reinforcement
Soil screw retention walls, in conjunction with shotcrete facing, offer a superior method for reinforcing the earth and constructing gravity walls. This innovative approach provides a cost-effective and time-efficient alternative to traditional soil retention systems.
By utilizing soil screw retention walls, you can eliminate the performance uncertainties and costs associated with grouted soil nails, especially in low shear strength soils. The load-bearing capacity of each soil screw is directly correlated to the applied torque, providing a clear understanding of its strength. This not only enhances performance but also helps to reduce costs.
Soil screws are typically installed at shallower depths compared to helical tieback anchors while retaining similar soil masses. The helical wall screw anchors feature bearing plates distributed along their entire length, while the true-spiral helices facilitate easy installation with minimal soil disturbance. Crucially, soil screw anchors do not require tensioning after installation; they serve as passive elements. Once installed, a soil screw retention wall securely holds the soil as a single mass with sufficient internal stability. Monitoring the torque during installation accurately indicates the expected holding capacity, ensuring predictable and reliable results.
The installation process for soil screws is swift and efficient, thanks to the use of common equipment such as mini-excavators and skid-steer loaders. This allows for quick rotation and placement of the soil screws. The size and grid spacing of the wall screw anchors are tailored to local soil conditions and specific load requirements, further optimizing their performance.
