ABSTRACT:
A method is disclosed for the construction of structures for tunnels, culverts, and pressure pipes of any size and shape, straight or curved, constant or variable cross section. The method requires very little formwork, with all work done on site. The method discloses the casting of a lower half of the structure as a continuous element, and the method of utilizing this half as a form in which modular lengths of the upper half of the structure are cast, lifted, inverted, and lowered to form the complete structure. Various methods are disclosed for joining the modules comprising the upper half of the structure to provide various degrees of structural continuity and fluid tightness.
