The overhaul notch 11 is formed in the side, facing the upper layer structure 3, of the large-diameter anti-seepage pipe 1 in the length direction, so that most of the area, facing the side of the upper layer structure 3, of the large-diameter anti-seepage pipe 1 is an open space, not only is the installation and construction of the drain pipe 4 facilitated, but also maintenance, overhaul and observation of the drain pipe 4 are facilitated.

The drainage route refers to a path from a starting point of a drainage pipeline to each destination, namely, a running position of the pipeline, and is a main basis for pipeline routing construction.

In order to facilitate the sleeve arrangement of the drain pipe 4 in the large-diameter anti-seepage pipe 1 to form a whole and facilitate the sufficient accumulation of water leaked from the drain pipe 4 in the large-diameter anti-seepage pipe 1, the water is effectively prevented from leaking in important rooms; the pipe diameter of the large-diameter anti-seepage pipe 1 is preferably twice that of the drain pipe 4; of course, the ratio of the pipe diameter of the large-diameter leakage preventing pipe 1 to the pipe diameter of the drain pipe 4 is only one of the preferred, and the specific ratio of the pipe diameters is not limited, and in other embodiments, the pipe diameter of the large-diameter leakage preventing pipe 1 may be two-point five-times or three-time the pipe diameter of the drain pipe 4.

In order to facilitate the large-diameter anti-leakage pipe 1 to fully enclose the drain pipe 4, effectively avoid water drops leaked by the drain pipe 4 from leaking in important rooms, and facilitate maintenance, overhaul and observation of the drain pipe 4, a part of one third of arc length of the large-diameter anti-leakage pipe 1, which faces one side of the upper structure 3, is cut along the length direction of the large-diameter anti-leakage pipe 1 to form an overhaul notch 11; the dimensions of the service notch 11 are only one preferred, and are not limited to the specific dimensions, and in other embodiments, the large-diameter leakage preventing pipe 1 is cut away from the side of the upper layer structure 3 along the length direction of the large-diameter leakage preventing pipe 1 to form the service notch 11.
