HYDRAULIC STRUCTURE Russian patent published in 2010 - IPC E02B3/12 E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to construction of coast-protecting, anti-erosion and barrier hydraulic structures, which include gabion masonry. Structure comprises masonry made of gabions, net baskets of which are filled with stone material. Surface of masonry in the area of its coupling with base and/or part of structure has broken shape with angular indents and/or bulges. Masonry comprises additional elements, which smoothen surface of masonry and/or fill cavities between gabions inside masonry. Additional elements are made of hard foam, which represents foamed cellular plastic with tightly sealed pores and having elasticity and compression strength at 10% linear deformation of at least 0.04 MPa. Each additional element is arranged in the indent and fills it and/or adjoins the bulge and blunts it. Masonry at the bottom and from sides is enclosed into geomembrane, and in case of permafrost, masonry at the bottom and at sides is enclosed into heat-insulation shell.

EFFECT: invention makes it possible to simplify works in erection of structure and to increase its reliability.
