PURPOSE: A subsurface water drain apparatus using a drain belt is provided to increase the discharge capacity of subsurface water and to reduce maintenance expenses. CONSTITUTION: A subsurface water drain apparatus using a drain belt comprises a first drainpipe(110), a second drainpipe(120), a connection socket(130), and a drain belt(140). The first drainpipe and the second drainpipe are made of hollow pipes at a regular interval. The connection socket connects the first drainpipe and the second drainpipe to form a gap between the first drainpipe and the second drainpipe. The drain belt is inserted in the connection socket along with the first drainpipe and the second drainpipe. The drain belt is expanded to the gap part between the second drainpipe and the first drainpipe. |
