SU1528839A1 - Counter-mudflow structure - Google Patents

Abstract

The invention relates to hydraulic engineering, in particular to dams, which delay and regulate mud flows. The purpose of the invention is to extend the service life, reduce labor costs by reducing the size of the structure and improving the reliability of the structure by making it possible to control the sediment deposition process in the upstream structure and skip part of the mudflow to the downstream. A dam 1 is installed on the mudflow path, installed at a certain angle in the direction of the mudflow movement in order to reduce the magnitude of the impact force and increase the dam's stability. A through passage is made in the dam, combined with channel 2 to its full height. With catastrophic and heavy mudflows, the main part of the sediment is deposited on the upstream of the structure, and through the mudflow channel 2 only a certain amount of the liquid phase and sediment is discharged to the downstream, which are subsequently transported along the lower part of the channel. 2 Il.

mudslides. At low and domestic expenses of mudflows, the construction makes it possible to dump the main part of the mudslide through channel 2 to the downstream, since such costs of the mudflow do not cause any harm and are freely transported along the lower section of the channel.

The invention provides the possibility of regulating the process of deposition of mudflow before construction, by passing a certain part of the mudflow through the canal, thanks to the combination of a blind dam with a throughput channel. As a result, the filling rate of the headwater is sufficiently weakened, which, at a given service life of suction catchers, makes it possible to significantly reduce the height of the structure.
