DRAIN APPARATUS FOR SUCTION DRAIN METHOD

摘要

PURPOSE: An insertion body for drainage increasing the durability of a connector is provided to increase reliability about a vacuum consolidation construction method by smoothly operating a vacuum pressure. CONSTITUTION: An insertion body for drainage increasing the durability of a connector is provided to comprise a drain board and a connector(20). A drain board comprises a skeleton perpendicularly divided by multiple drainage passages, a non-woven fabric installed in the outer side of the skeleton, and an impermeable layer formed in the outer surface part of the upper part of the non-woven fabric. A connector in which the upper end of a drain board is inserted comprises a cap(21) and a screw pipe(22). A cap comprises an inner layer(21a) fused with a drain board by heat, an outer layer(21b) having a heat resistance, a reinforced fiber layer(21c) installed in the outside of the outer layer and comprised of fabric, and an ultraviolet cutoff layer(21d) installed in the outside of the reinforced fiber layer and blocking ultraviolet rays. A screw pipe is installed in the one end of a cap, and is screwed with the fastening nut of a connection pipe.
