ABSTRACT:
A lightweight tubular housing open at both ends is specially constructed so as to be buried in the earth to almost its full height and yet withstand thrust forces of fill material. For this purpose the housing has outwardly curved side walls, it is tapered to a larger dimension toward the bottom, and its walls have an increasing outward curvature toward the bottom. The front wall of the housing is of less height than the rear wall to provide front access to the equipment. An inverted cup-shaped cover closes the upper open end of the housing and has a hinged connection that allows it to be opened or to be readily disconnected. To allow the housing to be buried throughout most of its height if necessary as well as to provide a large area at the lower portion of the housing for storing excess length of cable and for adjusting the cable laterally for convenient hook-up to the equipment, the front access opening preferably extends only a minimum distance down from the top relative to the over-all height of the enclosure.
