<p>The present invention relates to a device for connecting a double drainpipe embedded in a slab, which is formed by including a hard outer pipe embedded in a floor slab by having both ends inserted into a drainpipe connecting part of a first floor drainage trap embedded in the floor slab of a first faucet use space installed closely to a standing drainpipe and connected through the standing drainpipe to be connectable and a second floor drainage trap embedded in the floor slab of a second faucet use space separated from the standing drainpipe; a soft wrinkled pipe inserted into the hard outer pipe to connect the first floor drainage trap to the second floor drainage trap; and a packing block combined with both ends of the soft wrinkled pipe by screws in the first and second floor drainage traps and sealing and fixing the soft wrinkled pipe by being inserted into the drainpipe connecting part of the first and second floor drainage traps while horizontally extending the soft wrinkled pipe in the hard outer pipe. Thus, the performance of draining domestic sewage is improved and a stagnating phenomenon causing bad smell is prevented.</p> |
