Facilities for buried pipelines to design marks to cross the small rivers and streams

摘要

The construction for the burial of the pipeline to the project marks transitions through small rivers and streams.; The invention relates to pipeline transport, construction for the burial of the pipeline to the project marks transitions through small rivers and streams is intended to provide a temporary watercourse at work on the pipeline burial to design marks transitions through small rivers and streams.; The object of the utility model is to facilitate penetration of the pipeline process to design marks transitions through small rivers and streams.; Proposed construction design for the burial of the pipeline to the project marks transitions through small rivers and streams includes two dams, under construction before and after the transition of the pipeline, a temporary watercourse (tube or tray, or, in the case of the need for high capacity, multiple large-diameter pipes or trays).
