Description

outside the backfill. The tubular support boxes are provided with perforations. Perforations are also provided in the walls of the shells at the level of the tubular support boxes. Tubular, supporting boxes have a slope towards the reservoir. When the structure is erected, before installing the shells on the ground inside them, tubular channels 6 are made, the ends of which lead to the outer surface of the shells. During the filling of the inner cavities of the outer shells with filtering material, in the channels 6 they form windows. The tensioning of the anchoring rods 8 is carried out through the windows, the backfilling is performed in layers. 2 sec. and 1 z. p. f-ly, 5 ill.

The invention relates to hydraulic construction and can be used in the construction of moorings, embankments, retaining walls, etc.

The aim of the invention is to increase reliability and reduce the cost of mooring facilities. .

1 shows a mooring structure, a view in plan} in FIG. 2 - section A-A in figure 1} in FIG. 3 — section B — B in FIG. 1 in FIG. 4 — node I in FIG. FIG. 5 — node II in FIG. one .

The mooring structure contains extreme 1 and middle 2 (the number of the latter depends on the size of the mooring structure in plan) cylindrical shells, flanked by bank support boxes 3 on the bank side, supported by blocks 4. The tubular support boxes 3 are set obliquely, with their highest facing to the shore, the points coincide with the mark of the maximum water level in the reservoir, and the top mark of the ducts 3 at the place of their discharge into the reservoir coincides with the mark of the minimum water level in the latter. The tubular support ducts 3 are perforated along the entire length, i.e. have holes 5, designed for the flow of water into the reservoir. The cylindrical shells 1 and 2 are provided with tubular channels 6 intersecting them, placed at an angle to each other in plan. On the sides of the mooring structure there is a fence made of separate vertical tongue-and-groove elements 7, connected with anchor rods 8 placed inside the extreme tubular channels 6. Tubular channels 6

additionally connected to the walls of the cylindrical shells 1 and 2 with ribs 9, made of rolled steel. The cylindrical shells 1 and 2 are rigidly connected to the tubular supporting boxes 3 that hang around them, for example, using welded brackets (not shown), and in places of abutment

tubular support ducts 3 are provided with openings 10 serving to remove water that can enter the internal cavities of shells 1 and 2. On the coastal side, cylindrical shells 1 and 2 are surrounded by a backfill made of two parts: placed above tubular supporting ducts 3 folded from coarse stone material, the backfill 11 and the remaining space between the shells 1 and 2 and the walls of the excavation, composed of unsorted filter media (which can be

for example, slag of metallurgical processing is used) with backfill 12. The internal cavities of cylindrical shells 1 and 2 are filled with ballast (not shown), also consisting of unsorted filter media. Anchor ropes B are provided in the central part with lanyards 13, with the help of which they are tensioned, in order to carry out

The tubular channels 6, inside of which the anchor rods 8 are located, are provided with windows 14. On the bank side, the anchor rods 8 are fixed to the plates 15 placed in the backfill 12. The horizontal shells 1 and 2 on top are joined by the plate 16 using

anchor plates 18, fixed in the soil array 19 outside the backfill 12.

In the plate 16, windows 20 can be made to add, if necessary, ballast into the cylindrical shells 1 and 2 into the internal cavities. Recesses 21 can be made on the upper surface of the blocks 4 to fix the tubular support boxes 3 more accurately.

The construction method of the mooring facility is carried out as follows.

Inside the cylindrical shells 1 and 2 prepared for installation, tubular channels 6 are placed and fixed to the walls of cylindrical shells 1 and 2 by means of stiffeners 9 made of rolled steel. At the end of the earthworks and preparation of the foundation, the installation of blocks 4 is started, in which, if necessary, depressions 21 are made. On the mounted blocks 4 are placed tubular support ducts 3, in the walls of which perforations are made in advance. The tubular support ducts 3 are installed with an inclination towards the reservoir, while the elevation of the ducts should vary from the highest point facing the coast and the corresponding elevation of the maximum water level in the reservoir to the lowest points located at the outlets of the duct 3 in the reservoir and corresponding minimum water level in the latter. After installation, the tubular support ducts 3 proceed to the installation of cylindrical shells 1 and 2, which are mounted on the base with support on the tubular support ducts 3 and are connected to the latter. After that, at the junction points of the cylindrical shells 1 and 2 with tubular support ducts 3, the walls of the cylindrical shells 1 and 2 are perforated. The sides of the mooring structure are fenced off from separate vertical tongue and groove elements 7, to which anchor rods 8 with lanyards are attached 13 in the central part, after which the anchor rods 8 pass through the extreme tubular channels 6 placed inside the cylindrical shells 1 and 2. Then proceed to the end

The filling of the backfill, which is carried out in layers, in each layer is first poured a part composed of an unsorted filter media, and then a part composed of coarse-grained stone material. During the filling process, anchor plates 15 are placed into one of the layers of unsorted filter material, to which ends of anchor bars 8 are passed, passing through the extreme tubular channels 6. The inner cavities of the cylindrical Shells 1 and 2 are filled with ballast (not shown) using an unassorted the filtering material is the same as for backfilling 12. When the ungraded filtering material is reached in the outermost shells 1, level 1 ;, the placement of the tubular channels 6 in the central parts of the latter forms windows 14, through which The tensioning of the anchoring points is g 8 s.

25 using lanyards 13. After that

finish the ballast dumping into the internal cavities of shells 1 and 2 and proceed to the manufacture of a plate 16 joining cylindrical shells 1 and 2 on top. The plate 16 is anchored with the help of t 17 and anchor plates 18 fixed in the soil mass 19 outside the backfill 12. If necessary, in the plate 16 form a window 20, designed

 for ballasting into the internal cavities of cylindrical shells 1 and 2.
