The invention relates to a water falling energy dispersing and plastic filtering inspection well and belongs to the technical field of municipal administration drainage pipeline engineering. The waterfalling energy dispersing and plastic filtering inspection well comprises a closing-up well body, a well body, a water inlet, diversion holes, a strengthening rib, diversion filtering holes, a filtering collecting tank, a draining opening, a straight-wall well body and a base strengthening rib. The closing-up well body is connected with the well body, the water inlet is connected with the well body, the diversion holes are located in the inner wall of the well body, the inner wall of the straight-wall well body and the outer wall of the filtering collecting tank, the diversion holes are arc kidney-shaped long holes coinciding with the inner wall of the well body, the inner wall of the straight-wall well body and the outer wall of the filtering collecting tank, the strengthening rib is arranged in the well body, the filtering collecting tank is arranged in the well body, the diversion filtering holes are formed in the bottom of the filtering collecting tank, the straight-wall well bodyis connected with the well body, the draining opening is formed in the straight-wall well body, and the base strengthening rib is arranged at the bottom of the straight-wall well body. By means of the water falling energy dispersing and plastic filtering inspection well, a double-wall thin layer is adopted for water flow energy dispersing, the energy dispersing efficiency is improved, and impurity collecting and removing are facilitated through filtering collecting.
