ABSTRACT:
A modular rail car unloading pit which supports railroad tracks and facilitates the removal and transfer of aggregate, particulate, or other material from rail cars. The modular unloading pit is comprised of a set of precast concrete panels enabling the unloading pit to be environmentally friendly, reusable, and reducing installation time and cost. The set of panels includes one or more floor panels, four equally spaced vertical lateral walls oriented perpendicular to the railroad tracks, and a vertical longitudinal wall oriented parallel to the railroad tracks. Each lateral wall includes rail support plates at the top and anchors protruding from the bottom. The anchors are inserted into corresponding anchor receiving orifices in the floor for connecting the lateral walls to the floor. The lower end of the lateral walls are capped by metal channel members which are welded to metal plates on the top surface of the floor. The longitudinal wall is notched enabling it to interface with an end of each lateral wall. A conveyor system is mounted between each pair of lateral walls for transporting the material discharged from bottom unloading rail cars to an above-ground area away from the railroad tracks.
