PORTABLE PIPE BRIDGE

摘要

A portable pipe bridge has an adjustable-length, horizontal truss for supporting one or more temporary pipelines above a roadway. The truss is supported on each end by a vertical column having foldable footings and a elevator section which lifts the truss to a desired height. One or more temporary pipes are placed across the truss and coupled to pipelines on either side of the roadway. For transportation, the truss includes a fold-away trailer hitch yoke and two foldable wheel gear which may be deployed to convert the truss into a trailer. Each vertical column folds flat and fits onto the truss/trailer for relocation to a new site.
