Dam frost heaving prevention protection structure and construction method
The invention discloses a dam frost heaving prevention protection structure and a construction method. Protection plates are sequentially and fixedly connected to the upstream side in the length direction of a dam, a gap is formed between every two adjacent protection plates, a plurality of protection holes are formed in each protection plate at intervals, and the protection holes are formed in the length direction of the protection plates. The protection plates are cut into two halves in the width direction along the longitudinal section passing through the center line in the width direction of the protection plates, the protection holes are isosceles trapezoid, each protection plate is provided with two working faces, the side close to the dam is a first working face, the side relatively away from the dam is a second working face, the shorter bottom edge of the trapezoid is located on the first working face, and the longer bottom edge is located on the second working surface. According to the dam frost heaving prevention protection structure, damage of static ice pressure of ice to the dam can be effectively reduced, the protection holes with the narrow inner portions and the wide outer portions are adopted, the static ice pressure of the ice can be reduced, and maintenance and cleaning in the dry season are facilitated.
本发明公开了一种堤坝防冻胀防护结构及施工方法，防护板沿堤坝长度方向依次固连在迎水侧，相邻两个防护板之间具有间隙，每个防护板上间隔开设有若干个防护孔，防护孔沿防护板的长度方向设置；沿过防护板宽度方向中心线的纵截面将防护板沿宽度方向切成两半，防护孔为等腰梯形，防护板具有两个工作面，靠近堤坝的一侧为第一工作面，相对远离堤坝的一侧为第二工作面，梯形长度较小的底边位于第一工作面上，长度较大的底边位于第二工作面上。本发明所述防护结构可以有效的减少冰的静冰压力对堤坝的损坏，而且采用内窄外宽的防护孔形式，不仅可以减小冰的静冰压力大小，还方便在枯水期时的维护清理。
