The diameter of the top cover 8 is larger than the exhaust pipe 10, so that it can be supported on the upper end of the exhaust pipe 10, and then under normal conditions, the hinged plate is covered on the exhaust pipe 10 by gravity. When the exhaust is upward, the hinged plate is pushed to rotate upward.

[0027] In an optional embodiment, the adhesive layer can be a WTN self-adhesive polymer shaped geotextile, and a root-blocking adhesive strip is provided under the drainage ditch 11. The root-blocking adhesive strip can be an asphalt strip.

A plurality of spray pipes are evenly distributed in the overlying soil layer 9. The spray pipes extend longitudinally. The upper ends of the spray pipes extend out of the overlying soil layer 9 and are connected with spray heads, so as to irrigate the greenery above the overlying soil layer 9. The lower ends of the spray pipes are correspondingly connected to the water outlet end of a water pump through a water supply pipe. The water inlet end of the water pump extends into the water storage module. The water storage module drains and collects the rainwater, thereby realizing the recycling of rainwater.

[0035] The observation well is located outside the underground building and extends longitudinally below the guiding pipe, so that the bottom of the observation well is lower than the guiding pipe, and the rainwater flowing down at the observation well can be precipitated, thereby reducing the impurities entering the water storage module. The observation well is communicated with the guiding pipe. Specifically, the observation well is located at the side of the guiding pipe. An interface is provided at the part of the observation well lower than the guiding pipe, and the interface is communicated with the guiding pipe through a U-shaped pipe.
