Reinforced concrete components for the rapid construction of small structures - culverts - surface ducts - underground passages for pedestrians or light vehicles

摘要

The invention relates to a set of pre-engineered reinforced concrete components for the rapid construction of small structures - Culverts - Surface Ducts - Underground Passages for pedestrians or light vehicles. Each structure consists of components fitting the road size of a maximum of 2.40 m - L-shaped elements - Base slab - Roof slab, which are keyed together, with an added elastomer seal. IMAGE
