The invention provides a high-pressure water jet flow shield machine. The machine comprises a cutter disc, sliding spray bases, water cutter spray nozzles and a water supply tank; containing grooves are formed in the cutter disc; the sliding spray bases are slidingly arranged in the containing grooves and internally provided with placement cavities; the water cutter spray nozzles are installed inthe placement cavities and face the outer side of the cutter disc; the water supply tank is installed at the inner side of the cutter disc and connected to the water cutter spray nozzles through a pipeline. The high-pressure water jet flow shield machine solves the problem that when an existing shield machine is used for cutting underground buildings with original high intensity, a metal cutting tool is large in loss.
