Abstract

An underground container has, in the upper region, a plinth-like open frame which encloses a box-like container to accommodate electronic subassemblies. The open frame prevents the penetration of water and dirt during mounting and repair work. The plinth-like open frame accommodates a sealing cover and a load bearing cover, both of which help prevent the penetration of water and dirt after installation of the container.
