ABSTRACT:
A connection structure of plate type vertical drains and a circular horizontal drainpipe and a method of constructing a horizontal drain layer in soft ground using the same. The plate type vertical drains are coupled to the circular horizontal drainpipe using cylindrical fitters, so that excess pore water can be easily drained from underground even if the horizontal drain layer is constructed by pouring soil instead of sand, thereby reducing construction costs and a construction period.
