Abstract
The disclosure concerns a modular liquid collection system for use on the roadbed of a railroad, particularly at fueling stations. The modules are arranged end-to-end along the track, and are composed of precast components made of reinforced concrete or foamed plastic. In the most complete form, each module includes a central basin which rests on the ties between the rails, and a pair of side basins which rest on the ties at the outboard sides of the rails and which are formed with integral curbs. The basins have liquid-receiving surfaces which are pitched in both the transverse and longitudinal directions and have centrally located drain openings which overlie a transverse drain trough. The basins of the end modules of a series are equipped with removable end curbs.
Claims23
A liquid collection system for the roadbed of a railroad which includes a pair of parallel rails supported by longitudinally spaced ties, the system comprising
- a. a series of collection modules arranged end-to-end along the roadbed and each of which includes at least one rectangular precast basin which rests on a group of ties and extends alongside at least one of the rails,
- b. said basin having an upper, liquid-receiving surface defined by four planar faces which slope downward and direct liquid flow toward a centrally located drain opening,
- c. said basin also having internal locking means arranged to engage oppositely directed tie side faces to limit movement of the basin in the direction of the rails,
- d. each module also including a precast drain trough located between an adjacent pair of ties beneath said drain opening and extending transversely of the roadbed to a region beyond one end of the ties, and
- e. the drain trough having a discharge opening at said region.
A liquid collection module for use on a railroad roadbed which includes a pair of parallel rails supported by longitudinally spaced ties, the module comprising a rectangular, precast basin having a length which permits it to span a plurality of ties and a width which enables it to fit along-side the outboard side of a rail without overhanging the adjacent ends of the ties, the basin including
- a. a bottom having a flat, planar bearing surface arranged to rest on the upper faces of the ties, depending, integral locking means arranged to engage oppositely directed tie side faces to limit movement of the basin in the direction of the rails, and a longitudinally extending recess at its inboard side which is sized and shaped to provide clearance for the rail base and its attachments to the ties;
- b. a centrally located drain opening extending vertically through the basin;
- and
- c. a top having a liquid-receiving surface defined by four planar faces which slope downward and direct liquid flow toward said drain opening, and an integral curb which extends longitudinally along the outboard side of the basin and projects above the liquid-receiving surface.
A liquid collection module for use on a railroad roadbed which inludes a pair of parallel rails supported by longitudinally spaced ties, the module comprising a rectangular, precast basin having a length sufficient to span a plurality of ties and a width which enables it to be placed between the rails with its sides closely adjacent the rail webs, the basin including
- a. a bottom having a flat, planar bearing surface arranged to rest on the upper faces of the ties, depending, integral locking means arranged to engage oppositely directed tie side faces to limit movement of the basin in the direction of the rails, and a longitudinally extending recess at each side which is sized and shaped to provide clearance for the adjacent rail base and its attachments to the ties;
- b. a centrally located drain opening extending vertically through the basin;
- and
- c. a top having a liquid-receiving surface defined by four planar faces which slope downward and direct liquid flow toward the drain opening.
