By adopting the technical scheme, the anti-slip grains are arranged on the concrete base, when the five-way pipe is placed on the concrete base, the concrete base can sink, and the anti-slip grains can effectively prevent the five-way pipe from sliding on the concrete base, so that the stability value of the concrete base is higher.

To sum up, the utility model discloses a beneficial technological effect does:

1. the drainage treatment is carried out by arranging the main drainage ditch and arranging the permeable pipe in the main drainage ditch, so that the phenomenon that the geomembrane jacking support is damaged by air in soil before and after the reservoir stores water and during the water level change can be prevented, and meanwhile, the damage of the permeable pipe can be effectively prevented and the service life of the permeable pipe can be prolonged as the geotextile is arranged and comprises the permeable pipe;

2. the threaded connection end cover of the upper end opening of the five-way pipe can facilitate the drainage treatment of the external water pipe and is convenient to install or clean when detached.
