RETAINING-REGULATING STRUCTURE ON SOIL-FILLED FLOOD BED AND METHOD OF ITS ERECTION Russian patent published in 2012 - IPC E02B7/02 

FIELD: construction.

SUBSTANCE: structure comprises a water-retaining shell with water outlet lower and upper windows, fixed to the upper part to coastal anchor supports by a guy cable system. The shell is made of composite materials with shape memory and is fixed in the lower part on the flood bed. The flood bed is made of soil-filled shells connected to each other by means of flexible joints with memory to preserve design position of the structure and changing their parameters at the same time. Channel anchors are made of soil-filled or other multi-shell elements that ensure stability of the water-retaining shell and the flood-bed. Shells that prevent floatation and vibration of the structure arranged along its perimetre at different height and length are fixed to the guy cable system. On a soil-filled downstream apron there is a baffle plate installed of filled or membrane type. The structure is erected in a manner that includes laying shells into the prepared channel, which are connected by flexible joints, along the channel perimetre, laying a channel anchor of multishell elements, to which elements of the soil-filled downstream apron are fixed with the baffle plate from soil-filled or membrane shells, with filling of shells with pulp, fixation of a water-retaining cloth by flexible joints to the channel anchor, strengthening the upper part of the water-retaining cloth with the guy cable system to coastal anchor supports. Shells that prevent floatation and vibration are fixed to the guy cable system. Shell filling with pulp is carried out by means of its connection at one end to a pipeline sleeve that supplies a water-soil mixture, and at the other end - with a nozzle connected to a pipeline that discharges clarified water. The pulp is compacted due to its supply into a shell and discharge of water from it at the other side of the shell or via its filtering parts. Filling is carried out until the rated pressure is achieved in the shell.

EFFECT: improved structure reliability.
