Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering, in particular to structures of marine shore protection structures made in the form of a bun. The purpose of the invention is to increase the work efficiency by increasing the intensity of wave quenching and deposition of the forming material. The block contains an array with a trapezoidal outline in the plan, vertical end faces 2 and 3 with vertical groove 5 and a protrusion 6 and inclined side edges 4. On each side face 4 in its middle part there is a longitudinal recess outlined along a duct curve in cross section with the formation of a helical surface 7 with a rise in the direction of the face 2. In the middle part of the array, transverse through-holes 8 are made. The Buna, made of blocks, has a lateral surface of a saw-like shape, which provides damping nergii wave stream. Further, the tray is twisted by surfaces 7, divided by holes 8 into parts, parts of the flow are collided, and energy is lost. 7 il. (/) C VI VI about Ј

Description

FIG. C

FIELD OF THE INVENTION The invention relates to hydraulic engineering, in particular to structures of marine shore protection structures made in Reed Boon.

The purpose of the invention is to increase the efficiency of work by increasing the intensity of wave quenching and deposition of the plazoobrazuyuschey material.

1 shows a section of the groan, top view; figure 2 is a view of And figure 1; on fig.Z - view B in figure 2; figure 4 - block, in a perspective view; FIG. 5 is a section B - B in FIG. 1; figure 6 - section G - G in figure 1; figure 7 - section D - D in figure 1.

The block contains an array 1 with a trapezoidal outline in the plan, vertical, face faces 2 and 3 and inclined side edges 4. On the larger edge 2, a vertical groove 5 is made, and the smaller edge 3 is made with a vertical protrusion 6. On each the lateral face A in its middle part is made with a longitudinal recess outlined along the Korobovy curve in cross section with the formation of a helical surface 7 with a rise in the direction of the larger end face 2, and in the middle part of array 1 there are transverse through holes 8. When mating blocks y (1) has a side surface groynes sawtooth shape in plan view.

Claims (1)

When a wave flow is applied to the bun, the sawtooth-shaped form of the buna walls dissipates a part of the flow energy, surfaces 7 ensure the flow winding, impact of flow parts, in the holes 8 the flows are further divided into parts, which also collide. provides the precipitation of the plating material. Claims of the block The block contains an array with a trapezoidal outline in plan, vertical end faces and inclined side faces, with a vertical groove made on the larger end edge, and the smaller one is made with a vertical protrusion, characterized in that an increase in the intensity of wave quenching and deposition of the forming material, on each side face in its middle part a longitudinal groove is made, outlined along a duct curve in cross section with mations helical surface with a rise in the direction of greater end face faces, wherein a middle portion of the array through holes formed transverse. 2 Type B Ръ.З 6 Fig 5 Schi g L
