The Trac Trenching manhole cutter allows us to quickly dig manholes for construction sites. The manhole cutters allows us to quickly and efficiently cut a manhole for any contractor or general construction site.
The following is a step-by-step process of how our efficient manhole cutting works for a complete road reconstruct, which corresponds with the numbered photos to the left.
- GPS Location of structure.
- Cut the Structure.
- Remove the Slug.
- Vac all loose material.
- Remove Plate.
- Install MDOT approved collar with Thermo-plastic molding that is resistant to hydrogen sulfide gas, which prevents utility erosion over time.
- Trim collar to heights and slope.
- Install casing.
- Pourconcrete to bottom of flange or 2" below top. Asphalt the remainder.
Also Available on Mill & Fill Jobs - We are able to mill around structures out to a diameter of 54" to the depth required. (Photos 10 & 11)
