To drain the groundwater quickly.

In addition, the double drain pipe 40 uses the separate socket 50 directly connected to the drain board D to connect the drain board D into which the groundwater is introduced. (D) is communicatively connected and connected to the sump 30 to allow the groundwater to drain into the sump 30.

As such, when the drain board (D) and the double drain pipe (40) is installed, the discarded concrete (2) is poured thereon, and then the bottom concrete (3) is poured to form a drainage structure.

The pressure reducing pipe 20 is formed in an inclined U shape that rises and falls by a predetermined height, and is connected to an end of the water collecting well 30 of the double drain pipe 40 and positioned above the water collecting well 30. Here, when the groundwater inside the double drain pipe 40 rises and rises slowly, the upper extension pipe 22 of the decompression pipe 20 rises up by a certain height, and then descends through the downward extension pipe 24 to collect water. Discharged to (30). Therefore, the pressure reducing pipe 20 maintains and adjusts the up water pressure constant on the floor of the building to maintain an appropriate level of up water pressure so as not to be unconditionally overdrained, and the upper extension pipe of the pressure reducing pipe 20 ( Only underground water passing through 22) is discharged to the sump.

To prevent excessive discharge of large amounts of groundwater. In the case of such a pressure reducing tube 20, the siphon phenomenon may occur due to the ground water flowing through the internal cross-sectional area of the pressure reducing tube 20. When the siphon phenomenon is generated in this way, the groundwater at the high position of the upper extension tube 22 is generated. As it descends, low pressure and vacuum are formed internally, and the groundwater in the lower position is drawn up and discharged.

Accordingly, the pressure reducing tube 20 for preventing the siphon phenomenon is configured in such a manner that the upper end of the upper extension tube 22 is opened, so that the groundwater whose water level rises to the open portion overflows and the groundwater due to the siphon phenomenon.
