STORM OR WASTE WATER CHAMBER FEATURING STRAIN RELIEF NOTCHESFOR IMPROVED FLEXIBILITY AND CONTOURING THE CHAMBER

摘要

A chamber is provided that is flexible and able to be contoured along the entire length of the chamber when deployed on rock and earth formations with variable gradings. The chamber has a multiplicity of stress relief notches (also known as flex ports) formed on both sides at the base of the chamber substantially along the entire length of the chamber. A separate stress relief notch is formed between respective pair of protruding ribs along substantially the entire length of the chamber so the chamber can flex in an accordion-like or caterpillar-like manner. The chamber may be molded to include the strain relief notches.
