Description

Noah axis spurs to the upper and lower tails.

Gobies 1 can be made of separate blocks 6 of variable height, mounted on piles 3.

The longitudinal axis of the spur is located at an angle of 90-110 ° C to the direction of the dynamic axis of flow 7.

Significant curb weight and streamlining-. The shape of the concrete blocks, mounted on single masts, driven to a depth below the line of possible erosion, reduces erosion around the bulls, their stability and uniform lowering into erosion.

The shape of concrete blocks with rounded edges on the side of the upper and lower pools improves streamlining, ensures their durability and integrity during cruise fractions moving along the bottom of the river, and the trapezoidal channels formed between them, extending from the longitudinal axis of the spur towards the upper and The downstream pool does not prevent large floating objects from passing through the openings of the spur and their deposition in the interspire space.

With the passage of channel-forming costs and flood waters, a part of the stream passes through the spur channels and tends to discourage the main stream, which goes around the head of the spur, away from the protected shore or the earth roadway. The trapezoidal shape of the channels, extending from the longitudinal axis of the spur towards the upstream, increases the flow through the through part of the spur, thereby increasing the effect of the hydraulic barrier on the main part of the flow, which in turn increases

and the omission of all floating objects.

The expansion of the channels in the direction from the longitudinal axis of the spur to the upper and lower tails contributes to an increase in the flow through the through part of the spur and to a decrease in erosion around the bulls. The economic profitability of the invention, due to the reduction in the total cost of building the plugs and the cost of a unit of length of shore protection, compared with the known type of construction, rises 1.5-2 times depending on

local conditions.
