Abstract
An underground service protection system made from two main sections, a first frame having a bottom panel with hinged side and end panels and a second frame having side and end panels. The end panels retain inserted slides having half apertures. The half apertures surround a pipe or other structure being protected while the first frame and second frame form a protective cage. A standpipe and a back-fill gauge extend upward from the protection system. The hinged ends and sides enable the first frame to be installed with reduced material removable. The first frame and the second frame are aligned and held together using stakes on the first frame and pockets on the second frame. Tie wraps are used to hold the sides and the stakes and pockets together.
