Pre-stressed modular retaining wall system and method

Abstract

The present invention relates to a system and method for constructing a pre-stressed modular construction for supporting or retaining an applied load. In particular, the present invention relates to a system and method for pre-stressed modular retaining walls. The system comprises a plurality of header stacks constructed from a variety of header units. The header stacks are coupled by structural members. Active reinforcement elements are used to induce a pre-stressing force into the header stacks to support or retain the applied load. A method for constructing the modular construction is provided.

1 . A system for constructing a pre-stressed modular construction for retaining or supporting an applied load, comprising: 
 a header stack, wherein said header stack is comprised of a plurality of header units wherein said header units are stacked one on top of another to thereby provide contact between adjacent header units in said header stack; and    an active reinforcement element configured to cooperate with said header stack so that post-tensioning said active reinforcement element imparts a corresponding pre-stressing force into said header stack.
