BOTTOM OF THE SEWAGE PUMPING STATION Russian patent published in 2022 - IPC E03F5/22 

FIELD: sewerage.

SUBSTANCE: invention relates to the field of sewerage systems. The bottom (10) of the sewage pumping station contains a flat bottom part (11), a metal frame (13) at its base, as well as side walls (12). The connection of the bottom (10) with the sewage pumping station is ensured by fixing the side walls (12) to the body of such a station, as well as concreting the space formed between the bottom (10) and the body of the sewage pumping station. The bottom is made by manual molding of reinforcing fillers with a polymer binder containing layers of a mixture of binder and fibrous filler, where the layer of reinforcing fillers is impregnated with a binder based on unsaturated polyester and vinyl ester resins.

EFFECT: possibility to regulate the size of the bottom part of the sewage pumping station in such a way as to ensure the installation of the necessary number of submersible pumps and other equipment in accordance with the design assignment, while at the same time minimizing the area of the bottom itself, without changing the specified parameters of the housing, and also eliminate the risk of bending the bottom part of the station under the influence of groundwater force.
