Description

The invention relates to hydraulic construction, in particular to the construction of columnar and cluster supports, through racks, embankments and piers, erected on a steel foundation.

Known gravitational structure containing a block array, mounted on osymnom base 1.

The disadvantage of it is the laboriousness of its installation, which requires heavy-duty cranes.

There is a known method of erecting a balck structure consisting in delivering the assembled afloat to the installation site and feeding through it material under its base 2.

The disadvantage is that soil is used as a base material, which reduces reliability.

It is also known mooring structure on a rocky foundation, containing a slab of the upper structure, racks passed through the lower slab located on the base and the rear wall 3.

However, the construction requires the implementation of underwater planning works, which reduces labor productivity and, ultimately, reduces the technical and economic indicators of the berth, which increases the cost of construction.

A known method of erecting a mooring structure, which consists in delivering the structure assembled afloat by using pontoons to its installation site, is fed through the construction of the material first to the base and then to design 1.

The disadvantage of this method is that heavy-duty cranes are required for the erection of a structure, which increases the cost of erection.

The aim of the invention is to reduce the cost of erection.

The goal is achieved by the fact that in a berthing structure on a rocky foundation containing a slab of the upper structure, the racks passed through the lower slab located on the base and the rear wall, the racks are made in the form of pipes with anchor outlets at their ends, the base is in the form of a concrete massif, and the rear wall is in the form of a box, open at the top and mounted on a concrete massif, with the posts filled with concrete connected to the concrete massif.

In addition, the berthing structure is made in the form of a rack with struts.

According to the method of erecting a mooring structure, consisting in delivering the structure, assembled afloat using pontoons to its installation site, feeding the material structure first to the base and then into the structure, concrete is used as the material supplied to the base and the structure through pipes with anchor outlets, and as pontoons they use boxes with pipes in the bottom, through which, after installing them, concrete is fed under them.

FIG. 1 shows a section of the structure; in fig. 2 - separately standing rack; in fig. 3 - stand, incision; in fig. 4 - the same, option; in fig. 5 shows the node I in FIG. one.

The mooring structure consists of the slab 1 of the upper structure, columns 2, bottom plate 3, rear wall 4, concrete massifs 5 and 6, backfill soil 7, flooring 8, anchoring outlets 9 welded to the pipe are given on the parts. FIG. 2 given separately standing support, which consists of racks 2 supports, the bottom plate 3, the concrete mass 5. In FIG. 3, an option is provided for a stand alone support, which consists of a single stand 2, a support, a bottom plate 3, a concrete massif 5 or a support consists of a rack 2 support and a concrete massif 5.

The construction is as follows.

The slab 3 and the rear wall 4 rest on concrete massifs 5 and 6 mounted on a rocky foundation, the concrete of the massif being one piece with the concrete filling the stands.

The design works as follows.

From overturning the overpass, consisting of plates of the upper structure, racks 2 and plate 3, holds the weight of wall 4, as well as anchoring in concrete of array 5 through concrete filling racks 2 (if necessary, established by calculation, the concrete in the racks can be reinforced) , moreover, this concrete plays the role of tongs, perceiving shear forces (if necessary, the number of tongs can be increased).

The construction does not require a large consumption of concrete and the implementation of underwater planning works is reliable and economical.

The method of erection of the structure is carried out as follows.

An overpass, pre-assembled, is connected to the ducts forming the rear wall 4, which, afloat, are located on both sides of the viaduct. As such, the system is delivered to the installation site. Then, through the supports 2 and the pipes specially inserted into the bottom of the box of the rear wall 4, ready-mixed concrete is supplied, which goes under the plate 3 and the bottom of the box of the rear wall 4. The concrete is supplied until it fills the space under the plates 3 and 1 and partially or fully upright 2. To prevent the concrete from entering under plate 3 and 1 from spreading, it can be installed on the side

formwork After the concrete has gained strength (on the third, fourth day after concreting), the ducts located on the side of the cordon are removed.

In the construction of piers, conventional pontoons are used instead of the rear wall boxes 4.

When erecting a free-standing support, the bottom plate 3 can be concreted simultaneously with the concrete of the array 5, for which a wedge-shaped formwork extending to the bottom is suspended from the rack 2.

This method allows to simplify the construction of the overpass on a rocky foundation.
