Helical piles have been gaining notoriety as an ideal foundation solution for many types of trails, boardwalks, and walkways. The town of Ashland, Virginia sought a pedestrian and bicycle trail constructed to connect Carter Park to the existing Ashland trolley line trail. The trail is an easy half-mile walk along a very straight and level path. To connect Carter Park to the Ashland Trolley Line Park trail a boardwalk was needed over the steep embankment along Walder road. The Ashland Trolley Line Park Trail is a Greenway trail which is protected and managed for conservation and recreational purposes.
As with a foundation on a home, the foundation of a swimming pool can experience sinking due to unstable or poorly compacted soil. Ensuring a pool is constructed on a deep, lasting foundation will protect the owner investment and save them from costly future repairs. Whether you're a contractor building a backyard pool or an indoor aquatic center, starting on a firm foundation is key for the long-term success of any project, and there are a wide range of variables in the design process.
Helical piles are an established solution for foundation underpinning, but their applications are as far-reaching as the creativity of an engineer. Helical piles are typically associated with gravity load - force pushing down on the pile. In the project below, helical piles are utilized to support lateral loads, including wind and seismic loads.
In response to a demand for predictable high capacity foundation solutions, a fully grouted screw displacement pile was developed by CHANCE® engineers. Comprised of a centralized steel shaft and a patented displacement assemblies, the pile, known as the Drivecast™ screw displacement pile, is designed to create a cylindrical annulus around the central shaft that is continuously filled with grout from a gravity-fed reservoir at the surface.
Traditional foundation methods can be tricky to implement when access is limited, overhead clearance is especially low, or soil conditions call for strict weight limitations. For instance, on swampy ground or low-quality soil, the machines needed to install conventional foundations cannot always operate safely or maneuver effectively.
