Intermittent layer horizontal water leakage prevention structure of roller compacted concrete dam in severe cold area
The invention discloses an intermittent layer horizontal water leakage prevention structure of a roller compacted concrete dam in a severe cold area. The intermittent layer horizontal water leakage prevention structure involves a lower layer pre-poured concrete layer, an upper layer post-poured concrete layer poured on the upper part of a lower layer pre-poured concrete layer, possible horizontalcracks existing between the lower layer pre-poured concrete layer and the upper layer post-poured concrete layer, a preformed groove formed before the lower layer post-poured concrete layer pours theupper layer pre-poured concrete layer, geotechnical cloth is arranged at the position, close to the downstream side, inside the preformed groove, and the preformed groove is backfilled with clay. According to the structure, by backfilling the clay in the preformed groove, dam body water leakage is effectively prevented when the horizontal cracks exist, construction is convenient, investment is small, and the effect is good.
本发明公开了一种严寒地区碾压混凝土坝间歇层防水平漏水结构，包括下层先浇混凝土层，在下层先浇混凝土层上部浇筑的上层后浇混凝土层，在下层先浇混凝土层与上层后浇混凝土层之间存在的可能水平开裂缝，在下层先浇混凝土层浇筑上层后浇混凝土层之前设置的预留槽，预留槽内部在靠近下游侧设置土工布，在预留槽内部回填粘土。本结构通过预留槽内回填的粘土，有效防止水平开裂缝存在时坝体渗漏水的产生，且施工方便，投资小，效果好。
