PREFABRICATED REINFORCED CONCRETE WELL Russian patent published in 2024 - IPC E02D29/12 E03F5/02 

FIELD: water supply and sewerage.

SUBSTANCE: invention relates to devices for collection and removal of rain and melt water from ground road and airfield pavements. Prefabricated reinforced concrete well comprises a housing representing a reinforced concrete structure in the form of a hollow body with a uniformly protruding bottom along its entire diameter, and a cover. Housing is made in the form of a hollow square parallelepiped, consisting of two monolithic all-cast sections, the upper one with the ratio of sides equal in width to height A=B:K equal to 1:1, and a lower section consisting of a part duplicating the upper part of the well with the same ratio of sides to their height. Lower section, in its turn, is equipped with a base in the form of an all-cast bottom with thickness N and protruding from the side walls of the well on L. Above the bottom there is a tray that serves to ensure water drainage from the well, in the form of two round cutouts from below in oppositely located side walls of the lower section of the well. At that, the walls of the upper and lower sections are reinforced in two layers with a spatial frame made of A500C 8 mm reinforcement with pitch of 80 mm, and the bottom, in its turn, is reinforced in two layers with a spatial frame, in which the lower layer consists of A500C 8 mm reinforcement with pitch of 100 mm, and the upper layer is made of A500C 10 mm reinforcement with pitch of 100 mm. Besides, parts F-1 are installed between frames, made of A240C 6 mm reinforcement with pitch of 680 mm, which allows to prevent approach of frames during concrete pouring. Housing cover is made in the form of a flat monolithic all-cast plate with the ratio of dimensions of sides to height A=B:E, equal to 5:5:1, at the same time the plate in the centre is equipped with a through hole serving for installation of a cast-iron hatch.

EFFECT: invention provides operational reliability of the structure.
