Description

The invention relates to hydraulic structures and can be used in the design and construction of berths, embankments, retaining walls.

The purpose of the invention is to reduce material consumption, increase the reliability and stability of the structure.

Figure 1 shows the berthing facility, a vertical section; figure 2 - section aa in figure 1.

The mooring structure consists of anchor piles 1, immersed vertically and obliquely, the upper ends of which are connected by a foundation plate 2, which receives the load from vertical reinforced concrete columns. The upper ends of the columns are connected by additional anchors 4 to the base. To perceive the lateral pressure of the soil and the dynamic loads on the berth, horizontal reinforced concrete bolts 5 are mounted in the openings of columns 3, on which reinforced concrete slabs 6 are supported, enclosing the backfill soil array 7. In order to increase the strength of the backfill soil, it is layer-by-layer compacted to a relative density of 0.8 and reinforced with flexible hollow drains 8 (for example, fiberglass or polyethylene tape with metal woven wire mesh reinforcement). One end of the drain 8 is connected to the slab 6, and the other is anchored outside the caving prism. The combination of soil deformations and reinforcing drains is provided by installing disks 9 along them.

The backfill soil compacted to a relative density of 0.8 is protected by reverse

The 30 piercing moments are perceived by a system of supporting columns and girders, the foundations of which are surveyed with the base of their own. This eliminates the possibility of tearing and shearing, hectares along the base of the foundation, and vertical and horizontal loads and moments on the foundation are transferred to the base soil by the side surfaces and lower ends of the piles. As a result, the reliability and stability of the berthing structure increases during its operation.
