Description

The invention relates to mooring facilities and can be used when building. Ports of ports, marinas and other water transport facilities.

The purpose of the invention is to reduce the metal intensity of the shell.

The drawing shows a reinforced concrete shell, a horizontal section (shown one quarter of the shell, limited by the axes of symmetry, the remaining three quarters of the shell are similar).

The shell consists of reinforced concrete slabs 1 and 2, installed alternately along its perimeter. Plates 1 and 2 are made with ribs located on their edges and inclined towards each other. Plates 1 and 2 are installed with ribs in opposite directions and interconnected through the side surfaces of the ribs.

The angles of inclination of the edges of the plates 1 and 2 are chosen from the following equality:

 + g

gdesh is the angle of inclination of the ribs nlit 1;

 - the angle of the edges of the plates 2;

The y-angle between the planes of plates 1 and 2.

At the specified equality, the adjoining surfaces of the ribs are strictly parallel, which ensures a tight interconnection of plates 1 and 2.

At the joints of slabs 1 and 2, on the inner side of the shell, lugs 3, made of Dornite, hydrorina, used transport tapes or other 1 resistant materials, are installed.

The shell is assembled with a plate (template 4, which is a rigid metal frame, fixing the position of the plates 1.

The template 4 is installed on the ground based on the i.iariHH shell. Plates 1 are brought into the intended:; and.; Places for them, fixed by template 4, and lowered to the ground on the ground. The plates 2 with their ribs are filled between the edges of the plates I and also lowered to the ground on the ground.

In order to facilitate the installation of the shell between the plates 1 and 1 of plate 4, as well as between the edges of plates 1 and 2, small gaps are provided.

Plates are attached to the plates 1 or 2 prior to their installation into the shell. They are fastened with one edge using glue or embedded parts provided in the plates. The loose edges of the splashes 3 freely adjoin the adjacent slabs m.

After installing all nlit 1 and 2 template 4 is removed from the shell, and its inner space is covered with sandy soil. Splash bars, 3 prevent removal

soil from the shell.

Under the action of kkaktivnogo pressure of the soil backfill plates 1 and 2 are somewhat moved to the periphery, and the inner side surfaces of the ribs tightly pressed

to each other, preventing further movement of the plates.

Thus, a reliable connection is created for all the cladding plates.

During the construction of the mooring structure, in the form of a shell pier, they are installed with gaps between them, and as a solid wall, close to each other. In the latter case, the gaps between the shells overlap with crushed-stone filters or other known means, and the wall space is covered with soil.

During the construction of the berthing facilities of both types of shell, the monolithic or composite monolithic superstructure is combined over the top, the height and construction of which are determined by local hydrological and operating conditions.

In order to prevent soil erosion, the base of the shells is poured from the mooring side of a layer of large gravel or gravel.
