CONSTITUTION: A device(10) for draining underground water comprises a collecting well, a first underground water drain unit(20), vertical water pipes(50), horizontal pipes(60), connection pipes(70), and second underground water drain units(80). The collecting well is installed in one side of the underground of a building. The first underground water drain unit collects underground water from the underground(5), and discharges the collecting well. The vertical water pipes are connected to the first underground water drain unit. The horizontal pipes are extended from the vertical water pipes. The connection pipes connect the horizontal pipes. The second underground water drain units are connected to the horizontal pipes. |
