The invention relates to hydraulic engineering construction, in particular to the construction of plant protection structures used to protect objects from avalanches, landslides and landslides.

The purpose of the invention is to increase the operational reliability of the design.

FIG. 1 depicts a selector, general view; in fig. 2 - the same plan view; in Fig „3 - section A-A in Figo 2; in fig. 4 - protective elastic elements in the form of blocks from worn auto-fixing; in fig. 5 - possible options for the network of cables.

The through seleuver consists of a reinforced concrete beam triad 1, support washer 2, pillar 3 connected to inclined cables 4 forming a net 5, and protective blocks made of elastic elements 6 laid on the bottom of the bed 7 under the selector

and interconnected with

kami 3 using flexible connections 8.

Installation seleulovitel leads to Rusam. First, bearing washers 2 and triad 1 are set up according to the markings of the expansion axis, and their alternation depends on the calculated cross-section of the structure. Then the post 3 of the first row On the side of the upstream, it is wrapped with a cable 4, the ends of which, branching upwards along an inclined line, are pulled through the rack 3 of the second and subsequent rows of a selenium trap, and the connection of the cable with each subsequent row becomes rus The free ends of the cable are attached to the top point or the last row of pillars on the downstream side.

The formation of the network 5 in the body of the selectivator can be accomplished even after the completion of the mounting of the supporting elements by one of the methods shown in FIG. five,

After the installation of the support elements of the rack 3 is completed, the concrete is monolithic. At the bottom of the channel under the structure, protective blocks of resilient elements 6 are placed and they are tied together with each other and with stanchions with flexible connections 8.

The principle of work through seleulovitel. is that when the mudflow interacts with the structure, part of the load is perceived by the cables 4 and is transmitted to the pillars 3,

located in the depths of seleulovitel. Thus, the flow pressure is evenly redistributed along the supporting structures. Striking the cable 4, large inclusions freely fall on the protective block of elastic elements made of tire covers. Additional damping of the mudflow energy occurs due to the operation of cables that form a network penetrating the body of the mudflow, as the cable, elastically deforming and changing its position from each impact of inclusions, is elastic, reduces the speed and changes the direction of movement of large inclusions of the mudflow.

The network, having large cells, protects racks and triad beams from the direct direct transverse impact of large inclusions, thereby increasing resistance against abrasion by pumps, reducing the rate of fall of the components and reducing the impact load on the bottom of the bed. The diameter, slope and density of the network in the height of the rus of the seleklovitel depends on the power and nature of the mudslide.

The protective block consists of 7-10 of the HopieHHbix autocap joints, interconnected by flexible connections, forming a cylinder, and is laid at the bottom of the channel freely in the zones of expected erosion, i.e. in those areas where water and rockfalls are formed

The security units are interconnected and with the rack using flexible connections. When blocking, cylindrical channels are oriented in the direction of mudflow in order to fill channels with flood sediments to obtain a soil-rubber-reinforced protective layer.
