The invention provides a high-pressure water pipe. According to the high-pressure water pipe, two threaded bored line protrusions are arranged on the inner wall of a pipe body, the two bored line protrusions are arranged oppositely, the thread pitch of each bored line protrusion is larger than the inner diameter of the pipe body by five times, and the height of each bored line protrusion ranges from one twentieth of the inner diameter of the pipe body to one fifteenth of the inner diameter of the pipe body. According to the high-pressure water pipe, water can be ejected in a rotary mode, stability is higher, water scattering is unlikely to happen, and thus water can be kept in a centralized mode instead of a scattered mode in a longer distance after being ejected out from the orifice of the pipe; the water pressure in unit area is prevented from being increased excessively, and thus certain risks existing when the water pipe is in use are avoided to a large extent; due to the fact that a fixing block is arranged, it can be guaranteed that the high-pressure water pipe can be used for a long time under the fixed condition, and a user is free of the worry that the stability of the pipe body is affected by centrifugal force generated when water rotates.
