A vacuum consolidation drainage method using a drainpipe is provided to discharge a large quantity of underground water and to prevent the deformation of a drain board against earth pressure by installing a drainpipe which inhales and drains off underground water compulsively using vacuum pressure. The invention relates to a vacuum consolidation drainage method using a drainpipe for discharging the underground water, gathered in a drain board(310) after inhaling and filtering through a filter layer(320) of non-woven fabrics using a vacuum pump(400) connected to a drain connector(500), to the outside of the ground through a drainpipe(30) installed in the drain board using vacuum pressure, wherein support ribs are formed on the outer circumferential surface of the drainpipe at regular intervals to prevent the deformation of the drain board by earth pressure, through holes are formed on the outer circumferential surface of the drainpipe to increase the discharge quantity of underground water and to shorten the time required for discharging underground water respectively, and a packing is installed to the inside of the bottom of the drain board to make the inside of the drain board vacuous. |
