Abstract

The invention relates to hydraulic structures, namely to protective structures against the effects of mudflows. The aim of the invention is to increase the efficiency of the energy quenching of the flow. The energy absorber of the flow includes supply 1 and outlet 2 channels, side boards 3 of supply channel 1, obstacle 4 and channels 5. Mudflow moving along supply channel 1 is divided by obstacle 4 into two equal flows, which bend around channels 5 obstacle 4, directed toward it towards each other to extinguish their kinetic energy in the manner of opposing jets. Part of the flow moves along the frontal edge of the barrier 4, reducing its speed, and enters the channels 5. Reducing the flow velocity leads to its release from solid inclusions. The soothed and cleaned mudflow is removed to diversion channel 2. 1 C.p. f-ly, 2 ill.

The invention relates to hydraulic structures, namely to protective structures against the effects of mudflows.

The aim of the invention is to increase the efficiency of the energy quenching of the flow.

In the proposed device for quenching the kinetic energy of the mudflow, the effects of quenching by counter-jets, lifting, spreading and falling from a height are used. The decrease in the mudflow rate in FIG. 1 shows a current quencher of energy 5 leads to its release from solid state, plan view; in fig. 2 is a sectional view of the Breath of Inclusions, which makes it possible to obtain the sign of A-A in FIG. one.

The energy absorber of the flow includes the downstream I and outlet 2 channels, the side boards 3 of the inlet 1 channel and the obstacle 4 installed at its bottom with a frontal face mounted with a reverse bias towards the flow. Obstacle 4 with lateral sides 3 forms channels 5, which are directed beyond obstacle 4 towards each other.

The flow energizer works as follows.

The mudflow moving along supply channel 1 is divided by obstacle 4 into two equal flows, which channel 5 bends around obstacle 4 and directed towards 20 flow energy, the obstacle is made to each other to extinguish their kinetic in the form of a trapezoid with a frontal face energy Part of the mudflow rises, installed with a reverse bias towards the frontal face of obstacle 4, spread out along the stream and the water body interfacing with the bottom and flowing from it into the channels 5. Ustka, the diverting channel is made with a quiescent stream It goes to a diversion Russian-wide, smaller width of the supply line of the 225 channel.
