Artificial subsurface wetland with anti-clogging function

The invention belongs to an artificial subsurface wetland with an anti-clogging function, and belongs to the field of clogging prevention in wetlands. The artificial subsurface wetland with the anti-clogging function is characterized in that a water distribution pool, an underground box and a water collecting pool are connected in sequence; the water distribution pool and the underground box are connected by a water inlet tube provided with a water pump; the underground box sequentially comprises a soil layer, a matrix filter layer and a sandstone layer from top to bottom; a water distributiontube is arranged in the soil layer, the water distribution tube is provided with water outlet holes, the water distribution tube is connected with the water inlet tube, a water collecting tube is arranged in the sandstone layer, the water collecting tube is provided with water collecting holes, and a height difference exists between two ends of the water collecting tubes to make water in the water collecting tube natural
