PERFECCIONAMIENTOS EN LA CONSTRUCCION DE DISPOSITIVOS DE ALMACENAMIENTO SUBTERRANEO PARA GASES LICUADOS.

摘要

A large-scale in-ground storage facility for liquefied gas at cryogenic temperatures consists of an open cavity in the ground covered by an impervious roof sealed at its periphery to a ring-beam extending around the rim of the cavity, which is also sealed to the upper rim of the wall of the cavity. The ring-beam rests on a support structure which extends around the mouth of the cavity, and the ring-beam is mounted on the support structure by thermal expansion means which permit limited relative movement between the ring-beam and its support structure to accommodate thermal expansion and contraction.
