The present invention relates to groundwater drainage, and more particularly, to groundwater drainage for relieving both pressures acting by groundwater on civil engineering or building structures that are relatively lower than the groundwater level.

In general, when the final floor of the building structure is installed below the groundwater level, the positive pressure (buoyancy) is generated by the difference between the space excluded by the building, that is, the groundwater head difference between the floor of the building structure and the basement outer wall of the building structure. This positive pressure acts as a reaction against the weight of the building, which may damage the building structure, so it is necessary to adjust the groundwater level.

In particular, when constructing a large-scale building such as an apartment, underground parking is mandatory by law, and the underground parking lot of an apartment is located in a lower area due to the increasing trend of occupants and the desire to secure a green space. The effect of positive pressure on buildings is growing. Therefore, in order to prevent the positive pressure according to the variable groundwater level affects the building structure, the Permanent Anchor method and the Dewatering method are used.

The communication pipe 32, the second vertical pipe 31, the second extension pipe 33, and the drainage guide part 34 are drained to the water collecting well 100 or discharged to the rain pipe through the drain pipe 40. Thus, groundwater can be prevented from rising above the design stability.

When the groundwater level rises rapidly due to flooding or when the communication pipe is blocked and the groundwater cannot be smoothly drained, the groundwater is maintained below the design stability level by generating overflow water through the upper part of the first and second vertical pipes. Therefore, it is preferable to set the height of a 1st, 2nd perpendicular pipe so that it may not exceed design stability level. When the groundwater flows through the upper part of the first and second vertical pipes and flows to the floor of the building, the groundwater level can be stabilized within a short time by opening the valve 22a and draining the groundwater through the drain pipe.
