METHOD FOR CONSTRUCTION OF HYDRAULIC STRUCTURES ON ROCKY SOILS Russian patent published in 2024 - IPC E02B1/00 E02B3/06 E02D29/09 

FIELD: hydraulic engineering.

SUBSTANCE: when constructing a hydraulic structure of gravity type with vertical walls, self-drilling anchors of small diameter are pre-installed on rocky ground. Further, installation of spatial box-like frame structures without a bottom is performed, with subsequent filling of side surfaces with wall panel elements to form a closed volume. This internal volume is filled with available ballast. Spatial box-like frame structures without a bottom—finished frames of elements of a hydraulic structure—are coaxially installed on self-drilling anchors. Structures are installed on unprepared bottom surface. Irregularities of the bottom surface along the strip of contact with structures are compensated by elastic tubes integrated into the lower parts of the structures and filled with cohesive filler. Elastic tubes perform functions of compensator of bottom irregularities and provide anti-filtration protection of the band of conjugation of structures with bottom surface. Side surfaces of structures are filled with wall panel elements assembled into cassettes with tongue-and-groove profiles. Wall elements provide soil tightness of side surfaces of structures and accelerate erection of the structure. Method for construction of a port hydraulic structure is presented in the diagrams shown in Fig. 6–11. Fig. 6 shows the installation operation for installation of the first structure into the design position. Fig. 7 shows a marine installation operation for installation of subsequent structures, with fixation of coupled elements by means of locks-connectors. Fig. 8 shows an assembly operation for filling vertical structural elements and elastic tubes integrated into lower support surfaces with cohesive filler. Fig. 9 shows an installation operation for filling side surfaces of structures with wall panel elements. Fig. 10 shows an installation operation for filling the internal volume of structures with available ballast (rock, clay sand, sand, etc.). Fig. 11 shows installed in design position structures with device of upper structure envisaged by hydraulic structure project.

EFFECT: high-tech, relatively simple and considerably less labor-intensive industrial method of creating hydraulic structures on rocky soil, with a general reduction in material consumption of structures; in addition, the need for long-term diving operations is minimized, which enables to reduce the time and cost of operations.
