ENTRANCE WELL (VERSIONS) Russian patent published in 2012 - IPC E03F5/06 

FIELD: construction.

SUBSTANCE: entrance well is arranged in the form of a tubular reservoir with a bottom (2) and an inlet hole in its upper part. On the side surface of the reservoir there is a horizontal cylindrical take-off nozzle (11) for connection to storm water sewage. At the open end of the tubular reservoir there is a circular horizontal support ledge with a circular vertical board. In the upper part of the reservoir there is a horizontal inlet nozzle (7) with a dead plug (8) having a U-shaped profile, coupled in the upper part with the circular horizontal support ledge. The inner surface of the ledge is designed for installation and fixation of the U-shaped ledge arranged at the end of a connected rain-collecting tray. The horizontal cylindrical take-off nozzle (11) is arranged with a dead plug (12) at the side of the tubular reservoir and is installed on the side surface of the reservoir along the height so that the height of its bottom does not exceed the height of the bottom of the U-shaped inlet nozzle. The longitudinal plane of symmetry of the U-shaped inlet nozzle and the diametral plane of the horizontal cylindrical take-off nozzle are installed in one diametral plane of the tubular reservoir.

EFFECT: invention provides for universality and increased variety of versions for inclusion of an entrance well into different systems of rain drainage system, increasing stiffness and strength of the structure.
