Concrete dam overwintering interlayer anti-cracking construction method in severe cold area
The invention discloses a concrete dam overwintering interlayer anti-cracking construction method in a severe cold area. The method comprises the steps that lower layer first-cast concrete is poured, upper layer post-cast concrete is poured on the upper portion of the lower layer first-cast concrete after one winter interval, horizontal copper water stop and high-strength geocells are arranged on an overwintering interval layer between the lower layer first-cast concrete and the upper layer post-cast concrete poured on the upper portion, the overwintering interval layer is subjected to rough flushing treatment, then the upper layer post-cast concrete continues to be poured in the next construction period, and the whole construction process is completed. According to the construction method, the copper water stop and the high-strength geocells are arranged on the overwintering interval layer, horizontal cracking and vertical cracks of the upper layer post-cast concrete are effectively prevented, construction is convenient, investment is small, and the effect is good.
本发明公开了一种严寒地区混凝土坝越冬层间防裂施工方法，包括下层先浇混凝土，经过一个冬季间歇的下层先浇混凝土上部浇筑的上层后浇混凝土，在下层先浇混凝土与上部浇筑的上层后浇混凝土之间的越冬间歇层上布设水平铜止水及高强土工格室，并对越冬间歇层进行冲毛处理，然后在下一个施工期继续浇筑上层后浇混凝土，整个施工过程完成。本施工方法通过在越冬间歇层布设铜止水及高强土工格室，有效防止水平开裂及上层后浇混凝土竖向裂缝的产生，施工方便，投资小，效果好。
