The present invention relates to a temporary piping device for the flushing of a hydraulic pipeline, which can ensure stable flushing by selectively flushing a main pipe and multiple branch pipes even if the branch pipes with a small diameter are installed in the main pipe with a relatively large diameter, can perform complete flushing by removing a flushing fluid circulation obstacle part existing from a branch pipe divergence point installed at the final end of the main pipe to the end of the main pipe, and can obtain high-quality flushing in a short time by optimizing a flushing fluid flow in the main pipe. To achieve the above purpose, the piping device for the flushing of a hydraulic pipeline includes: a main pipe unit including a pressure supply pipe, a restoration pipe, and a drain pipe; and multiple branch pipes connected with the main pipe. The temporary piping device comprises: flange units which are installed the ends of the pressure supply pipe, the restoration pipe, and the drain pipe; and a temporary pipe unit which is installed in the flange unit in order to connect the pressure supply pipe, the restoration pipe, and the drain pipe, and opens or closes the flow of a flushing fluid through a vale so that the flow of the flushing fluid existing from the divergence point where the branch pipes are installed to the flange unit can be facilitated. |
