Multifunctional heat preservation formwork for high-water-head concrete dam in high-cold region
The invention belongs to the technical field of heat preservation of concrete dams in high-cold regions, and particularly relates to a multifunctional heat preservation formwork for a high-water-head concrete dam in a high-cold region, which comprises a polyurethane heat preservation layer, a concrete structure layer and a formwork main body of an ice-pulling-resistant coating which are sequentially arranged from inside to outside, pre-buried stainless steel parts are arranged at the edge seams of the inner side and the outer side of the formwork body, bolt holes and anchor pulling steel bars are arranged on the concrete structure layer, an anti-seepage structure is arranged at the edge seams of the formwork body, and the anti-seepage structure comprises at least two water stop strips arranged along the edge seams of the formwork body. A grouting pipe and a concave-convex water blocking structure are arranged between every two adjacent water stopping strips, each concave-convex water blocking structure comprises a protrusion and a groove which are located in two corresponding side seams of the formwork body respectively, and the protrusions and the grooves are matched. Effective annual construction time is prolonged, and construction procedures are simplified.
本发明属于高寒区混凝土坝保温技术领域，具体涉及一种用于高寒区高水头混凝土坝的多功能保温模板，包括由内而外依次设置的聚氨酯保温层、混凝土结构层以及抗冰拔涂层的模板主体，在所述模板主体内侧和外侧边缝处均设有预埋不锈钢件，且在混凝土结构层设有螺栓孔、拉锚钢筋，所述模板主体边缝处设有防渗结构，所述防渗结构包括沿所述模板主体边缝上设置的至少2道止水条，相邻两道止水条之间设置有灌浆管、凹凸阻水结构，所述凹凸阻水结构包括分别位于模板主体相对应的两边缝的凸起和凹槽，所述凸起和凹槽相配合，本发明抗冰拔、防渗、免拆除，拼缝封堵密封性好，安装省时省力，减少施工中的多重交叉干扰，延长年度有效施工时间，简化施工工序。
