Description

The utility model relates to coastal protection structures and can be used to protect coastal structures and coastal slope type from the effects of waves and ice from the waters of rivers, lakes, seas and oceans.

Similar solutions are known, containing reinforced concrete slabs laid in chains along a slope, anchoring elements and articulated joints (see, for example, descriptions of inventions to patents RU 2189421 IPC 7 E02D 17/20, Е02В 3/12 publication date 09/20/2002, RU 2129634 IPC 6 Е02В 3/12 publication date 04/27/1999).

The disadvantages of similar solutions is the insufficiently high reliability of protection, especially when exposed to ice during periods of hummocking and ice drifts, both under the influence of water and wind.

The closest analogue is a shore protection structure containing reinforced concrete slabs laid in the form of chains along the bank slope, anchoring elements and articulated joints (see, for example, description of patent for invention RU 2129634 IPC 6 Е02В 3/12 publication date 04/27/1999).

The disadvantage is the insufficiently high reliability of protection, especially when exposed to ice during periods of hummocking and ice drifts, both under the influence of water and wind.

The technical result is expressed in increasing the reliability of protection.

The essence of the shore protection structure is characterized by a combination of features common with the closest analogue, containing reinforced concrete slabs laid in chains along the bank slope, anchoring elements and articulated joints, and features that differ from the nearest analogue, namely: anchoring elements made in the form of pipe-piles, each reinforced concrete the stove is equipped

a metal cage covering the reinforced concrete slab on the sides, with holes in the joints of the reinforced concrete slabs with hinged joints, the parts of the metal cage opposite on the opposite sides of the reinforced concrete slab are interconnected by metal rods through box-shaped brackets open from the outside of the concrete slab, between the reinforced concrete slabs to the sides there are gaskets made of frost-resistant rubber with holes in which swivel joints are installed, the ends of which are bolted to metal holders, holes are made in each reinforced concrete slab, in which the ends of pipe-piles with ring gaskets made of frost-resistant rubber and flanges on the thread are located on them, and the pipe-pipes themselves are placed in previously performed drilling in the slope wells, the bottom row of reinforced concrete slabs rests on a foundation installed at the trench wall closest to the bank slope, which is dug in the bottom of the reservoir and covered with large pebbles or pieces of rock After the installation of the foundation.

The essence of the shore protection structure is illustrated by drawings, where in Fig.1 - placement of the shore protection structure on the bank slope in section;

The coastal protection structure contains reinforced concrete slabs 1 laid in the form of chains along the slope of the shore 2, anchoring elements 3 and articulated joints 4 (Fig. 1). Anchoring elements 3 are made in the form of pipe-piles 3 (figure 4). Each reinforced concrete slab 1 is equipped with a metal cage 5, covering the reinforced concrete slab 1 on the sides, with holes in the joints of the reinforced concrete slabs 1 by swivel joints 4 (Fig.3). The parts of the metal cage 5 opposite on opposite sides of the reinforced concrete slab 1 are interconnected by metal rods 6 through box-shaped brackets 7 open from the outside of the reinforced concrete slab 1 (Fig. 6). An example of a possible arrangement of metal rods 6 and box brackets 7 in a reinforced concrete slab 1 is shown schematically in the drawing (Fig. 5). Between the reinforced concrete slabs 1 on the sides there are gaskets 8 made of frost-resistant rubber with holes in which swivel joints 4 are installed, the ends of which are connected to the metal rings 5 by bolted joints (FIGS. 2, 3). In each reinforced concrete slab 1, holes are made in which the ends of the pipe-piles 3 with the annular gaskets 9 made of frost-resistant rubber and the flanges 10 on the thread are located on them (Fig. 4). Piles-piles 3 are placed in previously completed drilling in the slope of the shore 2 wells. The lower row of reinforced concrete slabs 1 rests on a reinforced concrete foundation 11 installed at the wall of trench 12, which is nearest to the slope of shore 2, which is dug in the bottom 13 of the reservoir and is covered with large pebbles or pieces of rock 14 after the foundation 11 was installed (Fig. 1).

Design and calculation of elements of a shore protection structure is carried out in accordance with applicable building codes and rules, for example, SNiP 2.06.08.82 LOADS AND IMPACTS

ON HYDROTECHNICAL STRUCTURES (WAVE, ICE AND FROM SHIPS).

All elements of the shore protection structure are manufactured in an industrial environment. Reinforced concrete slab 1 can be made with prestressed reinforcement 15 (figure 3). Installation of shore protection structures begins with digging at the shore 2 at the bottom 13 of trench 12 (Fig. 1). In northern regions with low winter temperatures, when a river freezes from shore 2 to the bottom 12, digging of a trench 12 and the entire assembly of elements of the shore protection structure can be carried out in winter time before the ice drift begins on the river. After the foundation 11 has been installed at the nearest to the slope of the shore 2 walls of the trench 12, the trench 12 is covered with large pebbles or pieces of rock 14. The lower row of reinforced concrete slabs 1 installed on the slope of the shore 2 is supported on the upper edge of the foundation 11. At the same time, before each subsequent installation (starting from the second) reinforced concrete slab 1, the installation of gaskets 8 of frost-resistant rubber and into the holes of the gaskets 8 of the swivel joints 4 with bolted connections to the metal cage 5 of their ends. Reinforced concrete slab 1 can be connected to the foundation 11 in the same way by swivel joints 4 with the installation of gaskets 8. After installing the next in a horizontal row reinforced concrete slab 1, supported on the foundation 11, it is connected to the previous slab 1 by swivel joints 4. Then it is sequentially installed in the same way with based on the foundation 11, the entire lower row of reinforced concrete slabs 1. Then, on the slope of the shore 2, reinforced concrete slabs 1 of the second row with spacers 8 and with unity to the reinforced concrete slabs 1 of the lower row by swivel joints 4. The third and subsequent rows of reinforced concrete slabs 1 are installed similarly to the slope of the shore 2, which

is determined by the possible rise of ice during ice drift and, especially, during ice jams, as well as the level of water rise during high water (Fig.1, 2).

The shore protection structure is especially effective in difficult conditions off the coast of water bodies. During ice drift, in particular, during the formation of ice jams, ice floes intensively destroy unprotected coasts. The mudflow and mud flows have a similar effect on the river banks. The coastal protection structure will withstand the action of ice floes or mudflows on it due to the structural strength and reinforced fastening of each reinforced concrete slab 1 with pipe-piles 3 to the shore 2. Flood waters will also not damage the river bank due to erosion due to the tight connection of the reinforced concrete slabs 1 due to the presence of gaskets 8 made of frost-resistant rubber.
