Case Study
Aerial Sewer System
SITUATION
On March 1, 2023, Cantsink was called in to assist with the
construction of an elevated sewer system in Winder, GA,
located at 333 Cosby Road. There was an issue with the
sewer system as it had to cross wetlands. The sewer system
needed to be elevated to ensure proper functioning for the
new residential subdivision. It needed a reliable foundation
solution to support the sewer system aerially.
Scope of Work
Cantsink's task was to install twenty helical piles to support the
elevated sewer system. Galvanized three-and-a-half-inch shaft
piles with ten-inch and twelve-inch helices were installed. These
were battered away from each other at 17.5 degrees off vertical
to provide compression, tension, and lateral load resistance.
Extensions (3.0-40X10) were added to reach the necessary depth
and achieve the required load capacity. The piles were installed
to depths ranging from 17.5 feet to 28 feet, with the deepest piles
achieving a 3500-pound capacity. Cantsink installed top plates,
support beams, Clevis hangers, and welding pipe casings to
complete the aerial support system for the sewer line.
Anchor System
The installation process was powered by an Eskridge 5016-21F54
drive head, providing up to 5,260 ft-lb of torque for efficient pile
penetration.
Result
The installation of the helical piles was completed without issues, and all piles exceeded the required load capacity of 2000 pounds. The piles were installed to specification, allowing the sewer line to function properly. Cantsink's efficient and effective solution ensures the sewer system will remain stable and secure for the long term.
