EXPANSION SEAM-WATER OUTLET Russian patent published in 2020 - IPC E02B3/16 

FIELD: building; hydraulic engineering.

SUBSTANCE: invention relates to hydrotechnical construction, namely to expansion joints, mainly protective lining of channels and water bodies, as well as when creating volumes of underground water reservoirs, for storage of wastes of various production, when seam can be located, including vertically. Strain sieve-outlet includes an anti-filtration element formed from film material, concreting plates immersed into concrete, and a cassette for forming deformation creases. According to the invention, for joining the plates there used is an element consisting of halves of the pipe, which are installed with the possibility of forming an internal space, and in the place of their joint – through slots, at that, half of the pipe on the lowering side of the relief, in the space between the plates, is perforated throughout the height, and the cassette is made in the form of an elastic material container installed on the central longitudinal axis of the docked plates, Note here that every plate has two unconnected webs of equal height through slits with their free ends inserted into element inner space through slots and diverging apart to frame inner surface of element every quarter of circumference length.

EFFECT: improving operating reliability of the expansion seam and water discharge and simplifying the technology of its creation, as well as realizing the possibility to control the water flow through the expansion seam.
