  • Hybrid arched overfilled structure
    Patent number: 7114305
    Abstract: A hybrid arched overfilled structure includes a combination of pre-cast side elements and at least one cast-in-place crown sector element. The side elements are pre-cast generally in a horizontal orientation and subsequently lifted into place. The crown sector element is cast in place between the side elements. In one form of the invention, each of the three sections makes up about one-third of the overall arch span.

  • Top arch overfilled system
    Patent number: 6922950
    Abstract: An earth overfilled arched structure includes a shallow arch spanning a clear space. The sides of the clear space are formed by curved or straight walls. Solidified zones of earth material (backfill or in situ) against the springs of the arch and/or behind the walls form foundation blocks which are in intimate contact via arch footings with the springs of the arch and/or with the upper part of the sidewalls in such a way that the arched structure delivers most or all of its support forces into the foundation blocks. These, due to their size and weight, transfer and spread the support forces to the subsoil so that displacements, especially in the horizontal directions, are minimal.
