Frost-damage-prevention near-water protection wall and construction method

Abstract

The invention relates to a frost-damage-prevention near-water protection wall structure comprises a protection wall body, an elastic isolation layer, a reinforced concrete cover plate and a reinforcedconcrete support. The elastic isolation layer is arranged on the rear side of the protection wall body, the reinforced concrete support is buried in a frozen soil layer, a polystyrene insulation board is laid on the elastic isolation layer in a terrace mode, cement mortar is arranged on the polystyrene insulation board, the reinforced concrete cover plate is lapped on the cement mortar, one end of the reinforced concrete cover plate is lapped on the reinforced concrete support, and the other end of the reinforced concrete cover plate is arranged on a protection wall stone support of the protection wall body. According to the method, the isolation layer is installed, so that the flat frost heaving stress generated by the frozen soil directly acts on the isolation layer, the flat frost heaving stress of the frozen soil is dynamically absorbed through elastic movement of the isolation layer, the flat frost heaving displacement is eliminated, the direct effect of the frost heaving soil onthe retaining wall structure is isolated, frost damage such as inclination, cracks and collapse of the retaining wall structure due to frost heaving flat displacement is avoided, the service life isprolonged, capital is saved, and the basic requirement for building a conservation-minded society is met.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a water-facing protective wall structure and a construction method for preventing freezing damage in winter. Background technique [0002] At present, the water-facing retaining wall structures of lakes and reservoirs in seasonally frozen areas in China are driven by the flat frost heave stress generated by the frost heave of the permafrost behind the wall, resulting in frost heave flat displacement and frost damage. The performance is that the excessive horizontal displacement of frost heaving causes the structure of the water-facing retaining wall to incline, crack or even collapse due to frost damage. This type of freezing damage occurs frequently in the permafrost regions in China, and the damage of freezing damage affects the normal use function of the retaining wall structure during the design period. The usual remedy for freezing damage is dem...

Problems solved by technology

[0003] Aiming at the problems of serious economic loss and environmental pollution in conventional disposal methods in the prior art, the present invention provides an antifreeze retaining wall structure. By installing an elastic isolation layer on the back of the retaining wall, the flat frost heaving stress can be effectively relieved and the retaining wall structure near the water can be protected. safety
