Abstract
A composite underground shaft lining assembly particularly suitable for use as a leak proof water conduit is formed with a plurality of annular concrete sections joined together by interposed layers of flexible joint material forming a composite concrete cylinder, with a composite steel cylinder formed of annular steel sections being arranged about the outer cylindrical surface of the composite concrete cylinder. The annular steel sections of the composite steel cylinder are joined together by spring rings located adjacent the flexible joints formed between the annular concrete sections.
Claims11
A composite underground shaft lining assembly particularly for use as a leakproof water conduit comprising:
- a plurality of individual annular concrete sections arranged in a generally aligned relationship to form a composite concrete cylinder, said composite concrete cylinder having an inner cylindrical surface and an outer cylindrical surface;
- joint means interposed between said annular sections joining said sections together, said joint means being composed of an intermediate layer of flexible material imparting a degree of flexibility between said individual concrete sections;
- a composite steel cylinder arranged about said outer cylindrical surface of said composite concrete cylinder;
- said composite steel cylinder comprising a plurality of individual annular steel sections and spring rings connected between adjacent steel sections in a water-tight manner joining said sections together to form said composite steel cylinder;
- said spring rings being located adjacent each of said joint means at said outer cylindrical surface of said composite concrete cylinder.
