Abstract
Systems and related methods involving isolation tubs are provided. In this regard, a representative system includes: an isolation tub formed of fiberglass reinforced plastic resin, the tub defining a reservoir; concrete positioned within the reservoir; and rails extending across the tub and being supported by the concrete, the rails being spaced from each other to form a special trackwork (STW) assembly.
Claims16
A system for forming a special trackwork assembly for a rail vehicle supported by first and second laterally spaced rails, the system comprising:
- a preformed center section having a perimeter edge;
- a preformed first side section having a perimeter edge;
- a preformed second side section having a perimeter edge;
- a preformed end section having a perimeter edge;
- first and second rail channels spaced from each other, wherein the rail channels are each configured as an elongate length of C-channel to receive the first and second laterally spaced rails, respectively, and wherein an interior surface of each of the rail channels comprises a lining of electrically insulative material;
- and
- a cap strip defining a top surface and having a channel facing away from the top surface;
- the center section, the first side section and the second side section being arranged such that the center section is positioned between the first side section and the second side section and bonded therebetween;
- the center section, the first side section, the second side section and the end section being bonded together to form a portion of an integrated tub defining a reservoir;
- corresponding portions of the respective perimeters of the center section, the first side section, the second side section and the end section defining an upper edge;
- the first and second rail channels extending across the upper edge from the reservoir to an exterior of the integrated tub such that the first and second rails are positioned adjacent the upper edge to engage wheels of the track vehicle;
- the cap strip extending along and being bonded to the upper edge such that the upper edge is received within the channel of the cap strip.
A system comprising:
- an isolation tub formed of fiberglass reinforced plastic resin, the tub defining a reservoir;
- concrete positioned within the reservoir;
- rails extending across the tub along an upper edge thereof and being supported by the concrete, the rails being spaced from each other to form a special trackwork (STW) assembly with the first and second rails being positioned to engage wheels of a track vehicle operating on the STW;
- and
- rail channels each configured as an elongate length of C-channel and positioned to receive the rails, wherein an interior surface of each of the rail channels comprises a lining of electrically insulative material.
A method for forming special trackwork assemblies comprising:
- arranging preformed fiberglass reinforced plastic resin sections at a location for a special trackwork assembly for a track vehicle;
- sealing joints between the sections to form an integrated tub;
- installing rail channels laterally spaced from each other, each of which is sized and shaped to receive a rail, at locations along an upper edge of the integrated tub such that the rails are positioned adjacent the upper edge to engage laterally spaced wheels of the track vehicle;
- and
- positioning elastomeric infill material within interior surfaces of the rail channels.
