Miller Park Sewer Separation Project
Special Designed Reinforced Concrete Jacking Pipe
American Concrete Products manufactured 2,300 feet of 60-inch diameter sewer for stormwater conveyance. The majority of the sewer (1,300 feet) was completed utilizing the micro-tunneling method of boring. Due to the site conditions, this custom designed reinforced concrete pipe was the only product considered for the tunneling operation.
The jacking pipe was designed according to ASTM C-76. It was decided to utilize a double O-Ring gasket spigot and a steel bell joint to take advantage of a larger jacking surface to allow jacking forces to increase while minimizing the number of intermediate jacking stations. Testing ports were placed between the gaskets to facilitate the testing of the joints prior to pushing and post-installation, as needed.
