Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to reduce material consumption, increase the reliability and stability of the pier. The wharf contains shells of large diameter, consisting of curved reinforced concrete slabs 1 and slabs 2, curved inward and flat to the outside, interconnected by flexible joints 3. On the elongated lateral edges 4 of the slabs 2, the slabs 5 are supported. which are on the side of the coast are the plates 8. The size of the shell along the axis, perpendicular to the line of the cordon, is larger than the size of the shell along the axis located along the line of the cordon. Internal backfill is made of soil and stone. 1 hp ff, 2 ill.

The invention relates to hydraulic construction, in particular to the construction of mooring and fencing structures using large-diameter shells with vertical partitioning.

The goal of the invention is to reduce the material consumption of the berth, increasing its reliability and stability.

FIG. 1 and: the berth is visible, as seen from the plan; in fig. 2 shows section A-A in FIG. one.

The berth contains shells of large diameter consisting of curved reinforced concrete slabs 1 and curved inward flat outside slabs 2 interconnected by flexible joints 3. The elongated side faces 4 of the slabs 2 are supported by slabs 5.

Adjacent plates 6 shells have protrusions 7, on which the plates 8 are supported.

The size of the shell along the axis, the perpendicular line of the cordon, is larger than the size of the shell along the axis located along the line of the cordon.

The internal backfill of the 9 shells, and the backfill 10 are made of soil. The space bounded by the shells and plates 5 and 8, covered with stone 11.

The shell is installed in the structure and backfilling 9 is performed. The shell under the action of the axisymmetric load from backfill 9 changes its shape in the plan, the flexible joints 3 do not interfere with this, and shear phenomena occur in the backfill 9, which leads to a change in lateral pressure backfill 9 on the wall of the shell.

Plates 5 and 8 are installed and backfilling 10 is performed, under the action of which the shell changes its outline in plan. In backfill 9, shear phenomena occur, which leads to a decrease in lateral pressure of backfill 9 on the shell walls. The space bounded by the shells and plates 5 and B is covered with stone 11.

The area of the berth construction from the Elliptical in terms of Shells is larger than the berth construction from cylindrical shells of the same diameter by about 15%. Placed between the shells in the backfill, the flat plate causes the appearance of friction forces that keep the shell from overturning, all of which increases the stability of the pier.

Plate 8 prevents the backfill 10 from washing out in the event of an emergency unloading of plate 5, which increases the reliability of the pier.

Claims (2)

1. A mooring that includes reinforced concrete shells consisting of vertical curved plates in plan with filler in the inner cavity of shells and between shells, with the face plate facing the water area made flat out with elongated side faces on which the front side of the water area and rear flat plates rest on the inner side to enclose the fill between the shells, characterized in that, in order to reduce the material intensity, increase the reliability and stability of the pier, the shells are elliptical in plan, and the major axis of the ellipse. The perpendicular cordon is located, and the symmetrically located plates of two adjacent shells are provided with protrusions facing the coast, on which the rear flat plate rests, while the ground is used as a placeholder for the shell cavity, and stone zasyok1k. , 2. He added that the joints between the plates are made flexible.
