Abstract

The invention relates to hydraulic structures and is intended to quench energy and detain mudflows. The purpose of the invention is to increase the efficiency of depletion of the mudflow energy and reliability in operation by increasing the fragmentation of the mudflow. The anti-salt device includes a springboard-type through construction, made of beams I connected to the diverging beam, the outermost of which are located at the bottom of the channel 3, and located between them are installed with a reverse incline increasing to the longitudinal axis of the pass-through structure. At the bottom of the channel 3 with equal intervals posted support beams 4, collected in the same beam. Each beam 1 is connected to proximal support beams by 4 pairs of inclined beams 5 "arranged in a checkerboard order along the length of the through structure, while the angles between the beams of 5 B pairs increase from the axis of the through structure to the banks 6 of the bed 3. When the mudflow interacts with against a settlement device, its structure is stratified across the channel 3 and the mudflow rises along beams I. If contacted with beams 1.4 and 5 located in different planes, the mudflow loses speed and extinguishes its energy. 4 il.

The invention relates to hydraulic structures and is intended to quench energy and detain mudflows.

The purpose of the invention is to increase the efficiency of the quenching of the mudflow and the reliability of operation by increasing the crushing of the mudflow. : Figure 1 shows the anti-mudflow device, general view, axonometrics J ijra of figure 2 - the same, plan | in fig. 3 shows section A-A in FIG. figure 4 - section BB in figure 2,

. i The anti-mudflow device is designed as an end-to-end tramp L | Ein type, including beams 1, United in a beam, diverging direction -) mud flow, the outermost of which are placed on the left 2 of the selenosny bed 3s and located between NTS and a reverse bias increasing towards the Lrodol axis through the design. A through structure installed in a selenos bed of 3 m is fixed on a support structure made of an ideally connected air flow - n | beam in the direction of the mud flow, and placed on the bottom 2 of the selenos bed 3 with equal interm support beams 4 are located in the spaces between the beams I and the transverse beams connected with them, such as jioHHbtt-iH beams 5. Each beam 1 is connected to two proximal support beams 4 pairs of inclined beams 5, Pairs of beams 5 are located in vertical planes across the through construction j equal to The ribs are distributed along the length of the through construction and are installed in a checkerboard pattern. The upper ends of the: aclon beams 5 are attached to the beams. 15 s lower cono - to the supporting beams 4. In addition to the TorOj, the angles between the n-aclonny beams 5 in pairs increase from the axial through structures to the banks of the 6 selenos bed 3. Support beams 4 are anchored into the bottom soil 2 of the selenos bed 3,. Beams 1, 4 and 5 can be made of obsolete railway rails.

When a mudslide interacts with the infusion of an anti-mudflow device, its structure is stratified across the channel 3 width and the mudflow rises along beams 1 through the trag-shlinny type. Contact

with beams 1, 4 and 5 located in different planes, the mudflow loses speed and extinguishes its energy. With the passage of the mudflow, the mass of the villages partly fills the device, increasing its stability, a part of the mudflow drops into the lower pool of the channel 3, and the other part slides along the sides of the device to the banks 6 of the channel 3. The arrangement of the beams 5 in pairs at angles increasing 6 banks of the channel 3, provides a smooth change in the structure of the mudflow, which in turn has a gentle effect of the mudflow on the natural surface of the channel 3.
