Anti-seepage and anti-freezing protection system for bank and side slopes of reservoir in cold region and construction method thereof

Abstract

The invention belongs to the field of side slope and bank slope protection engineering, and discloses an anti-seepage and anti-freezing protection system for bank and side slopes of a reservoir in a cold region. The anti-seepage and anti-freezing protection system comprises a foundation embedded in the side slope. A gravel cushion layer, a composite anti-drainage plate and a Renault protection padare sequentially laid from inside to outside on the slope surface of the side slope from the foundation to a set height of the side slope, wherein the set height of the side slope is higher than a surge water level. The anti-seepage and anti-freezing protection system further comprises one-way drainage pipes, wherein the one-way drainage pipes comprise a bottom one-way drainage pipe and a top one-way drainage pipe. The water inlet section of the bottom one-way drainage pipe penetrates through the foundation and extends into the side slope. The water inlet section of the top one-way drainage pipe penetrates through the Renault protection pad, the composite anti-drainage plate and the gravel cushion layer sequentially and extends into the side slope. The invention further discloses a construction method of the anti-seepage and anti-freezing protection system for the bank and side slopes of the reservoir in the cold region. The anti-seepage and anti-freezing protection system is simple in structure, reliable in function, convenient to construct, long in service life, and capable of effectively preventing erosion damage and seepage damage to the bank and side slopes of the reservoir,greatly weakening freezing and thawing damage to the side slope, and ensuring long-term stability of the bank and side slopes of the reservoir.

Description

technical field [0001] The invention belongs to the field of side slope and bank slope protection engineering, and in particular relates to a seepage and antifreeze protection system for reservoir bank slopes in cold regions, and also relates to a seepage and antifreeze protection system and construction method for reservoir bank slopes in cold regions . Background technique [0002] In reservoir bank slope and river bank slope engineering, problems such as wave erosion damage, seepage slope damage caused by reservoir water infiltration and water level rise and fall, and freeze-thaw damage on the slope surface have always been key problems in bank slope protection. [0003] At present, the bank slope of the reservoir is mainly protected by mortar rubble slope protection and Renault pads. Although these protective measures can resist wave erosion, they cannot prevent external moisture from entering the slope. When the water level outside the slope rises, the external water e...

Problems solved by technology

On the other hand, in the reservoir bank slopes in cold regions, after the water outside the slope enters the slope, the surface of the slope will freeze and expand at a certain depth in winter, causing the frost heave damage of the masonry rubble slope protection. When the spring melts, the surface of the slope will melt The masonry masonry that has been softened and damaged by frost heave fails to protect, and often causes thermal thawing and slumping; while the Renault pad is a flexible protection, although it will not cause frost heave damage, but because it is supported by the surface of the slope body, the edge When the surface of the slope softens, it is often slippery along with the slope, which cannot prevent the freeze-thaw damage of the slope
