The invention provides an assembly type drop well prefabricated part. According to the design, the construction period of a drop well and a drainage pipe network can be shortened; transportation and hoisting are facilitated; the problems of structural stability and seepage prevention of all components are solved; the water drop component well wall comprises a water drop component well wall body, a plurality of blocking bodies are arranged in the water drop component well wall body, ventilation pipes are arranged in the middles of the blocking bodies, a water drop well lower component is arranged at a bottom opening of the water drop component well wall body, and a water drop well upper component is arranged at a top opening of the water drop component well wall body. A drop well lid, a drop component well wall, a drop well lower component and the drop well upper component are arranged at the position of the drop well upper component, and the portions between the drop well wall, the drop well lower component and the drop well upper component are filled with anti-seepage materials, and the blocking body is used for connecting the drop component well wall and the ventilation pipe and used for slowing down kinetic energy and potential energy of water flow. And the anti-seepage material is added to the joint of different components and used for preventing rainwater or sewage in the drop well from seeping out.
