Abstract:

A liner plate structure, system and method is provided for lining of mine shaft bores, tunnels and the like. The liner plate structure includes a primary plate portion and at least one flange disposed at a side edge of the primary plate portion. A thermoplastic fusion element extends along an exterior surface of the flange. A liner structure within a shaft or tunnel includes at least first and second liner plate members assembled together, the liner plate members formed of metal plate material having respective metal surfaces in contact with each other along a plate joint. A thermoplastic fusion seal arrangement is located along the plate joint. A method of lining a mine shaft bore includes: providing a plurality of liner plate members, each liner plate member having a curved shape; assembling a first set of liner plate members into a first ring structure; assembling a second set of liner plate members into a second ring structure; mounting the second ring structure in abutting contact with the first ring structure; and forming at least one seal between the first ring structure and the second ring structure.

US Classification:

220565, 1562722

Abstract:

A tank assembly includes an elongated plastic tubular pipe structure and at least one end wall or internal bulkhead wall attached to the plastic tubular pipe structure. The end wall or internal bulkhead wall is a composite unit formed by a plastic sheet member sized to cover a cross-sectional area defined by the tubular pipe structure and a composite reinforcement strip bonded to the plastic sheet member. The composite reinforcement strip includes an elongated plastic base portion having a plurality of spaced apart ribs extending from a first side thereof and lengthwise therealong, each rib comprising an elongated metal reinforcement encased in plastic, the plastic base portion having a second side abutting against a surface of the plastic sheet member. Other structures can be reinforced using composite strips that are electrofusion welded to one or more walls of the structure.

US Classification:

220626, 295271

Abstract:

A tank assembly having an elongated plastic tubular pipe structure and at least one end wall attached to the plastic tubular pipe structure and sized to cover a cross-sectional area defined by the plastic tubular pipe structure. The end wall is a composite unit including a first plastic sheet member having an edge portion and a second plastic sheet member bonded with the edge portion of the first plastic sheet member. The first plastic sheet member is located inward of the second plastic sheet member, the second plastic sheet member having a body portion with an outwardly domed shape to define an internal space between the body portion and a body portion of the first plastic sheet member. A structural foam is disposed in the internal space to provide continuity between the first plastic sheet member and the second plastic sheet member.
