Jacobson Road Creek Crossing
- Location Wisconsin
- TimelineApril 2020
Michels Utility Services, Inc. was asked to rock bore a crossing under Jacobson Creek to install 400 feet of 4-inch polyethylene gas pipe. However, the length and depth of bore would have made it very difficult to renew gas service to the five homeowners affected by the crossing. Instead, Michels suggested damming the creek and digging across it. A Michels Dewatering crew developed a proposal to use an aqua dam to dam the creek and use 2 6-inch pumps to bypass the creek from one side of the road to the other. Because the rock was 6 inches below the creek bottom, the pipeline crew used an excavator with a hydraulic breaker to start excavating a trench that was 4 feet wide by 7 feet deep at creek bottom. The total length of the trench was 60 feet with a maximum depth of 12 inches.
The pipe was built above ground and placed in the trench once the excavation was complete.
