Diaphragm/ sea retaining wall system

Abstract

Diaphragm Sea/Retaining Wall System consists of retaining wall that spans horizontally between Deep Beam Diaphragms anchored into bedrock through rock socketed caissons. Deep beam Diaphragm is built of two round column sections that serve as vertical chords of the Diaphragm or as flanges of the Deep beam, and of the concrete web section continuously connected to both round columns. Fixity of the Deep Beam Diaphragm at the bedrock level is provided by embedment of two round column flanges of the Diaphragm into the predrilled rock sockets or caissons. Stiffness of the Deep Beam Diaphragm support and retaining wall reinforcement arrangement allows better force distribution between system elements and makes the system of present invention a most economical solution for difficult geotechnical conditions where large forces of static and dynamic nature has to be efficiently resisted by a retaining wall system. The present invention system is also the most reliable force resisting system for dynamic sign changing loads. The system can effectively resist seismic and static loads as well as large forces of wave action, and can be used for Ocean shore protection. Unique steel pipe concrete cast forms of the present invention and sequence of construction allow quick and efficient installation of the system in the most difficult conditions where top of bedrock elevation can significantly vary along the retaining wall length.
