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.
Platform Mill For Producing Helically Wound Pipe And Related Method
A pipe production system includes a plurality of platform segments that are coupled together at a construction site to form a work platform. A helical pipe production system is mounted on the work platform. The work platform includes an integrated drive system that enables the platform to be moved around the terrain of the construction site so that pipe can be produced in-line with an intended or desire pipe laying path.

International Classification:
B65D 90/08 B65D 88/76 B29C 65/22
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.

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.

Abstract:
A pipe joint includes a first pipe and a second pipe. The first pope has a first annular flange at one end, the first annular flange including a first end face. The second pipe has a second annular flange at one end, the second annular flange including a second end face. The first annular flange is mated to the second annular flange, with the first end face and the second end face facing each other and pressing at least one seal member therebetween. A plurality of axial retaining members are disposed around a perimeter of the mated first and second annular flanges to hold the pipe joint together.
Metal Foundation System For Culverts, Buried Bridges And Other Structures
A bridge system is provided that utilizes foundation structures that are formed of the combination of a metal-frame structure and cast-in-place concrete.
Reinforcement System And Method For Corrugated Plate Structures
A corrugated plate structure includes a plurality of corrugated plates connected together to form a corrugated structure having a corrugation direction and a cross-corrugation direction. A reinforcement system includes: a first bracket and a second bracket, where the first bracket extends substantially parallel to the cross-corrugation direction and mounted to side-by-side first and second corrugation crests so as to pass over a corrugation valley that joins the first and second corrugation crest, and where the second bracket is spaced in the corrugation direction from the first bracket, and the second bracket extends substantially parallel to the cross-corrugation direction and mounted to the first and second corrugation crests so as to pass over the corrugation valley. An elongated reinforcing member extends substantially parallel to the corrugation direction and mounted to both the first bracket and the second bracket.
