STONE-FILL HYDRAULIC STRUCTURE AND METHOD OF ITS ERECTION Russian patent published in 2011 - IPC E02B3/06 

FIELD: construction.

SUBSTANCE: structure is equipped with several retaining metal frames with stone fill both inside and outside around them, installed along the longitudinal axis of the structure at the identical distance from each other. The stone-fill prism along the whole length of the structure is made as double-layer and multi-fragmentary, with intraframe fragments concreted in the upper part. On top on the lower layer of stone fill and inside each retaining metal frame there is a flexible gasket, onto protruding parts of which at the outer side of the retaining metal frame there is a device installed to limit the area of upper stone-fill layer concreting. Upper ends of vertical metal rods are rigidly connected to reinforcement of a horizontal reinforced concrete plate. The method to erect a stone-fill hydraulic structure is characterised.

EFFECT: structure strength improvement.
