Anti-blocking perforated pipe for constructed wetland

The utility model belongs to the technical field of constructed wetland water distribution, and particularly relates to an anti-blocking perforated pipe for a constructed wetland, which comprises a water distribution pipeline communicated with a bell and spigot; the water distribution pipeline comprises a DN100 main pipe communicated with the interior of one side of the bell and spigot, the bell and spigot is connected with two DN50 perforated pipes communicated with the interior of the bell and spigot, and the two DN50 perforated pipes are symmetrically arranged; in rainy seasons, the sand content in inflow water can enter the water distribution pipeline along with the water inlet pipeline, as time goes on, growth of microorganisms and sediment are caused, when the water distribution pipeline is blocked, a worker closes a ground pump station and stops feeding water into the water distribution pipeline, then a bell and spigot connected with the water distribution pipeline is manually disassembled, and the wat
