The Job
This Wisconsin thermal grouting project by CJGeo is located in Sheboygan. As part of a grid-scale battery storage installation, contractors had to bore transmission lines under multiple railroad tracks. For ampacity management, the trenchless crossing required thermal grout in the bore annulus.
Placing the CJTherm TM-5 thermal grout.
The Challenge
This jack and bore crossing is approximately 250 feet, and 36 inches in diameter. The locally-available aggregate in the ready mix market was not suitable for achieving the specified thermal resistivity requirement.
The Solution
Site access.
CJGeo performed the thermal grouting using CJTherm TM-5 thermal grout mix. Since locally available material wasn't available, we utilized material manufactured offsite and shipped in. This approach removed all risk and cost of developing a project-specific mix for a low volume placement.
Pressure and temperature were monitored continuously and fed to the cloud. Peak heat of hydration was less than 95°F.
