[0046] When in use, one end of the drain pipe is rotatably connected to an already installed drain pipe to be docked, or installed at the installation location, such as hanging on an anchor rod when installed on the top of a mine, etc. The positioning and installation equipment is placed at the other end of the drain pipe, and should be placed directly below the installation location of the drain pipe. The drain pipe is installed on the semicircular frame 51 and fixed by the pipe lock chain 52, and the rotation handle 43 is rotated to lift the drain pipe, so that the drain pipe rotates around the fixed point at the other end until it reaches a suitable docking position.
