High-pressure water jet plug-drilling drill for lateral drilling

The utility model discloses a high-pressure water jet plug-drilling drill for lateral drilling. The high-pressure water jet plug-drilling drill is used for finishing a lateral drilling operation by forming large-diameter spray holes in cement test pieces and ground layers by utilizing high-pressure water jet. The high-pressure water jet plug-drilling drill comprises a drill base body (1) and a drill central body (2) which are connected to each other. The high-pressure water jet plug-drilling drill is characterized in that a plurality of drill side wings (3) are uniformly arranged at the periphery of the drill central body (2); a chip groove (8) is formed between two adjacent drill side wings (3); gauge protection teeth (4) are arranged on the surfaces of the outer sides of the drill side wings (3); cutting teeth (5) are arranged on the bottom surfaces of the drill side wings (3); nozzles (6) communicated with an inner cavity of the drill base body (1) are further formed in the bottom surfaces of the drill side wings (3); and internal threads (7) are arranged in the cavity. The high-pressure water jet plug-drilling drill for the lateral drilling has the advantages that the structure is simple, the rock breaking efficiency is high, and the working life is long; and the drill can be completely matched with a lateral drilling plug-drilling drill technique, so that the use ratio of energy can be substantially improved, and the drilling speed is higher than the normal drilling speed.
