Frost-damage-prevention near-water protection wall and construction method
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.
一种防冻害临水护墙结构，包括护墙本体、弹性隔离层、钢筋混凝土盖板、钢筋混凝土支座，护墙本体后侧设有弹性隔离层，钢筋混凝土支座埋设冻土层内，弹性隔离层上地坪铺设聚苯乙烯保温板，聚苯乙烯保温板上做水泥砂浆，钢筋混凝土盖板搭在水泥砂浆上，钢筋混凝土盖板一端搭在钢筋混凝土支座，另一端塔在护墙本体的护墙石支座上。本发明方法通过安装隔离层，使得冻土产生的平冻胀应力直接作用于隔离层，通过使隔离层的弹性运动，动态地吸收冻土的平冻胀应力，消除冻胀平位移，并隔离了冻胀土对护墙结构的直接作用，避免了冻胀平位移引起护墙结构的倾斜、裂缝、坍塌等冻害破坏，延长使用寿命，节约资金，符合建设节约型社会的基本要求。
