Over time concrete lined canals crack and deteriorate. Pipelines and culverts crack, corrode, leak, and function poorly. A problem solution for unlined canals is to install a reinforced plastic lining which is cheaper, more watertight, and more durable than concrete. For deteriorating concrete canals a reinforced plastic lining can be applied to the existing surface. A reinforced plastic liner can be installed in deteriorating pipelines or culverts. water control structures can be rehabilitated. These measures can be accomplished with a process and machine which mixes and assembles raw materials (plastic components and reinforcing fabric) at the job site, and applies this composite to the surface of a canal, ditch, pipeline, or structure. As the plastic cures it adheres to the underlying surface and creates a reinforced lining. The plastic used can be formulated to fit the requirements of the particular situation. The lining is durable, water tight, and does not have to be earth covered. The lining can be laid in continuous overlapping strips across large canals, or along the length of small canals. Deteriorating pipelines can be lined using an inflatable bladder surrounded by the plastic composite. This paper explains the process and gives examples of its use.born digitalproceedings (reports)engCopyright and other restrictions may apply.
