FIELD OF THE INVENTION The invention relates to mooring facilities, in particular to through mooring facilities.

Various pier designs in the form of a pile overpass are known, for example, pier overpasses on reinforced concrete, wood and metal piles. They consist of vertical or inclined piles and spans with bumpers and mooring devices. The stability of such structures under the action of horizontal forces is achieved by jamming piles in the ground.

However, under conditions of soft soils (silt, silty sands and limestone, dusty sands, etc.), the pinch effect is sharply reduced. Under the influence of horizontal forces, the pier loses stability. There is an emergency. Therefore, SNiP does not provide for the construction of such structures on silty and similar soils.

Naval marinas are close in design to these structures. They have the same drawback.

The closest to the invention in technical essence are light berths intended for loading and unloading operations and the mooring of ships. They consist of pile supports, spans, mooring and jacking devices.

Their disadvantage is the impossibility of operating the pier under conditions of soft soils due to the loss of its stability under the action of horizontal forces.

The purpose of the invention is to increase reliability by providing stability on soft soils under the action of horizontal forces. Thus, the invention allows the construction and operation of piers in the form of pile trestles in any geotechnical conditions.

This goal is achieved by the fact that in the pier in the form of a pile overpass containing pile supports, installed in several rows, spans, mooring and demolition devices, between the pile supports within the dimensions of the pile floor on the inner side of the extreme rows of pile supports are installed dead in this case, the pile supports are equipped with crossbars and stitches, the ends of the crossbars are fixed in the transverse, and the heads of pile supports in the longitudinal direction are pulled to the dead sterns.

In FIG. 1 shows a pier in the form of a pile overpass; in FIG. 2 - pile supports, plan; in FIG. 3 is a section AA in FIG. 1.

The pier consists of pile supports 1 with a span 2, including crossbars 3, mooring 4 and fender 5 devices; dead korea 6 with eyelets 7, transverse 8 and longitudinal 9 otth jaws with lanyards 10, yokes 11 and clamps 12 with annular eyelets 13, connecting brackets 14,

Reinforced concrete (type I, YaP, etc.)

or metal (e.g. segmented, helical) dead cores are installed by a floating or truck crane on the inside of the extreme row of piles. After steady-state sedimentation, core 6 is transverse to the ground.

the stitches 8 are fastened with a connecting bracket 14 at one end with a ring 7 cor 6, and the other end with a truss 13 connected to a metal clamp 12 at the ends of the crossbar 3. At the same time, longitudinal stitches are fastened with a connecting bracket 14 at one end with a ring 7 cor 6 , and at the other end - with a yoke 13 yoke 11, Under the action of longitudinal and transverse horizontal forces on the construction, a part of the arising forces

it is received by tags 8 and 9 and transferred to dead cores 6. For safety reasons, it is not recommended to set up dead cores outside the pile field for safety reasons.

Depending on the magnitude of the horizontal force and the physico-mechanical parameters of the soil, it is possible to calculate the required number and mass of dead Kores, the dimensions of the ribs, yokes, clamps

and connecting brackets, ensuring the stability and reliability of the operation of the pier. During operation of the structure, the tension of the hoses is regulated by lanyards 10.

Thus, the proposed construction of the pier for the first time allows the construction to be used under conditions of soft (silty) soil.

Economic effect of application

The new design depends on the passenger and cargo turnover of ships at each pier.
