Abstract

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering and is intended mainly for attachment of slopes sea wave-protection barriers structures. Protective coating of wave trap 1 of sea hydraulic structure includes blocks laid in two layers-upper layer 4 and bottom layer 5. Unit has to be filled with concrete flexible shell with through holes provided with nozzles for feeding into the concrete mixture. Units are arranged on the slope 1 so that openings in units of one layer are partially aligned with holes in units of another layer.

EFFECT: protective coating is created of wave traps of marine hydraulic structures, which provides avoiding the need in storage areas for manufacture and storage of concrete blocks, as well as allows to avoid the use of floating facilities.

Description

The invention relates to hydraulic engineering and is intended primarily for securing the slopes of marine wave protection structures.

A protective coating of slopes of hydraulic structures is known, containing reinforced concrete slabs with protrusions arranged in parallel rows with an inclination to the slope forming up to 60 °; the protrusions are made with a curved outer surface, while the vertices of the protrusions of the curved surface are shifted towards the downstream, and the distance between the ridges of the protrusions is determined from the relation

where t is the height of the protrusions, SU 1059052, publ. 12/07/1983.

This coating requires formwork of complex configuration directly on the slope both above the water horizon and below, which significantly increases the cost of the structure.

Known wave-extinguishing coating on the slopes of marine hydraulic structures, including shaped blocks laid in two layers, “Instructions for the design of sloping and end-to-end fencing structures and special underwater stands VSP 33-03-07 MO RF, M., 2008, p. 5, p. 5.1.8, http://files.stroyinf.ru/Data2/1/4293829/4293829061.htm (a copy of the link is attached).

This technical solution is made as a prototype of the present invention.

Its disadvantages are as follows. For the manufacture of a large number of shaped blocks (tens of thousands) special polygons are required, a very large area. For transporting the blocks to the storage location, where concrete is set up with the necessary strength, loading and unloading operations and related equipment are required. After that, the blocks should be delivered by water to the place of their installation on the slope. This requires special boats, berthing facilities, floating cranes, etc. As a result, storage, transportation and related construction costs account for about 40% of the cost of protective wave-extinguishing coating.

The present invention is the creation of a protective coating design for the slopes of offshore hydraulic structures, which eliminates the need for landfills and storage areas for the manufacture and storage of concrete blocks, and also eliminates the use of floating equipment.

According to the invention, in the protective wave-extinguishing coating of the slopes of offshore hydraulic structures, including concrete blocks laid in two layers, the block contains a flexible shell filled with concrete with through holes, equipped with fittings for supplying concrete mixture inside it, the blocks being placed on the slope so that the holes in the blocks one layer partially aligned with the holes in the blocks of another layer.

The applicant has not identified any technical solutions identical to the claimed one, which allows us to conclude that the invention meets the condition of patentability “Novelty”.

The invention is illustrated by drawings, which depict:

in FIG. 1 is a cross-sectional view of an offshore hydraulic structure;

in FIG. 2 - concrete block, top view;

in FIG. 3 is a section AA in FIG. 2;

in FIG. 4 is a section BB in FIG. 2;

in FIG. 5 - node B in FIG. 2;

in FIG. 6 - block of the upper layer, combined with the block of the lower layer, top view;

in FIG. 7 is a section GG in FIG. 6.

Protective wave-extinguishing coating of slope 1 of an offshore hydraulic structure, in a specific example of wave-breaking pier 2, includes blocks 3 laid in two layers - upper layer 4 and lower layer 5; block 3 contains a flexible shell 6 filled with concrete, made in particular of rubberized textile material. The shell 6 is made with through holes 7, in a specific example of a square shape. The holes 7 of one of the layers are partially aligned with the holes 7 of the other layer (Fig. 6). The flexible shell 6 is equipped with fittings 8 for supplying concrete mixture into it. Flexible shells 6 are transported along the crest 9 of the wave-breaking pier 2 by truck and put on the slope 1 using divers and a coastal crane moving along the crest 9. Then, the concrete pump and concrete truck are moved along the crest 9 from the shore, after which flexible shells 6 are filled with concrete mixes 8 The concrete blocks of the lower layer 5 are formed. Then flexible shells 6 are laid on them to form the upper layer 4 so that the holes in the shells of the lower layer 5 are partially aligned with the holes in b Okahim top layer 4 (FIG. 6). After this, the flexible shells forming the top layer 4 are likewise filled with concrete mix. When waves interact with concrete blocks laid in two layers with the displacement of the holes in the blocks of one layer relative to the holes in the blocks of the other layer, wave energy is quenched. The degree of extinction depends on a number of factors, of which one of the main ones is the voidness of the protective coating. The claimed wave extinguishing coating has a voidness of 40-50%.

The implementation of the distinguishing features of the invention provides a technical result, consisting in eliminating the need for landfills and storage areas for the manufacture and storage of concrete blocks, since their formation is carried out directly on the slope of the marine hydraulic structures. The use of floating equipment for the delivery and installation of blocks is not required.

The applicant has not identified sources of information that would contain information about the influence of the distinguishing features of the invention on the achieved technical result.

These circumstances allow us to conclude that the claimed technical solution meets the condition of patentability "Inventive step".

This technical solution is implemented using well-known, widespread materials and equipment, which determines its compliance with the patentability condition "Industrial Applicability".
