Water jet cutting tunnel boring machine

The invention relates to the field of tunnel boring machines, and discloses a water jet cutting tunnel boring machine. A cutter head is provided with a first hob, a second hob disposed perpendicularlyto the first hob and third hobs disposed outside the first hob and the second hob, and a plurality of third hobs are arranged; and high-pressure water outlets are formed, at the center positions of every two adjacent third hobs, in the cutter head, and the high-pressure water outlets are connected with a high-pressure pump through high-pressure water pipes. The water jet cutting tunnel boring machine overcomes the shortcomings of slow tunneling speed, low efficiency, high cost, long construction period of the existing tunnel boring machines and the like. 本发明涉及到隧道掘进机领域。水射流切割隧道掘进机，刀盘上有第滚刀、与第滚刀垂直布置的第二滚刀、布置在第滚刀和第二滚刀外侧的第三滚刀，第三滚刀有多把，彼此相邻的第三滚刀中央的刀盘上布置有高压水出口，高压水出口连接通过高压水管连接高压泵。本发明克服现有隧道掘进机掘进速度慢、效率低、成本高、工期长等缺点。
