A method and a device for mounting a hybrid-type underground filtered water collecting horizontal pipe are provided to prevent the horizontal pipe from being blocked and to obtain drinking water source with the pre-treated quality of water by a water quality improving filtering medium. A method for mounting a hybrid-type underground filtered water collecting horizontal pipe(3) installed horizontally to a vertical pipe(2) of a sump pit to secure drinking water source is composed of steps for mounting an entrance sleeve(31) to the vertical pipe to prevent the water or soil from being inserted; installing a horizontally driven drill shoe(32) to the entrance sleeve; connecting a deposited slit pipe and an input water pipe to the drill shoe and propelling a horizontally driven casing connected with the drill shoe by a propulsion device; finishing installing a horizontal well by continuously mounting the horizontally driven casings; removing the deposited slit pipe from the horizontal well and preparing to install a strainer(33) using the input water pipe as a filtering medium filling pipe; settling the strainer to the horizontal well and then mounting the strainer in the horizontal well; continuously installing the strainers by installing a water sealing ring(34) between the strainers; preparing to fill the filtering medium filling pipe with a filtering medium(35) for improving the quality of water; filling a space between the horizontally driven casing and the strainer through the filtering medium filling pipe; drawing and removing the horizontally driving casing and the filtering medium filling pipe of a part completely filled with the filtering medium mixed with the water between horizontally driven casing and the strainer; finishing filling an outer periphery of the strainer with the filtering medium; fixing a cut portion of the drawn casing and drawing and removing the casing and the filtering medium filling pipe; and mounting the water collecting pipe for securing drinking water source by installing a valve(6) to the end of the strainer. |
