Description

Anti-frost-heaving protection channel for cold region Technical Field The utility model relates to the technical field of cold region channel protection devices, in particular to an anti-frost-heaving protection channel for a cold region. Background The frost heaving damage and leakage of the channel are common problems in hydraulic engineering in northern cold areas of China, frost heaving can be generated on channel revetments in cold areas under the negative temperature effect, and frost thawing can be generated daily when the channel revetments are severe. Simultaneously bear the actions of frost heaving, ice load, water flow scouring and the like, and is easy to damage; The existing channel mainly adopts materials such as cement soil, concrete, asphalt concrete and membrane materials as an anti-freezing and anti-seepage layer of the channel, and after the anti-freezing and anti-seepage layer is subjected to repeated freeze thawing cycle action, frost heaving damage of the channel is obvious, channel maintenance cost is obviously increased in the subsequent maintenance process, and the running benefit of the channel is influenced, so that the cold area channel needs to be provided with a structure capable of effectively preventing frost heaving. Aiming at the problem of exposure in the use process of the current frost heaving prevention channel for the cold region, the improvement and optimization of the frost heaving prevention structure of the channel are necessary. Disclosure of utility model In order to solve the technical problems, the utility model provides an anti-frost-heaving protection channel for a cold region, which has the characteristics of frost heaving resistance, seepage resistance and water flow scouring resistance. The technical scheme is that the frost heaving prevention channel for the cold region comprises second geotextile uniformly attached to the surface of the channel, a layer of first geotextile is uniformly laid on the upper surface of the second geotextile, a first geotextile is uniformly laid on the upper surface of the first geotextile, a protection frame is uniformly attached to the upper surface of the first geotextile, a polyurethane protection layer is arranged on the upper surface of the protection frame, a frost heaving resistance layer is embedded in the protection frame, a plurality of hinge rotating shafts are uniformly embedded on a framework on the side face of the protection frame, and a plurality of protection frames are fixedly connected through locking nails in a locking mode during splicing.
