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. T he chamber has a multiplicity of stress relief notches (also known as flex ports) forme d 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.
