Overwintering heat preservation method for dam concrete in high-cold and high-altitude area
The invention belongs to the field of dam concrete construction, and particularly relates to an overwintering heat preservation method for dam concrete in a high-cold and high-altitude area. The top surface of the dam is constructed, specifically, a plastic cloth layer is arranged at the bottom, rubber and plastic sponge is arranged on the plastic cloth layer, a composite heat preservation structure is arranged on the rubber and plastic sponge, and canvas is selected as the composite heat preservation structure; steel pipes are adopted at the top of the composite heat preservation structure and continuously pressed and covered according to 3m * 3m grids, meanwhile, wind-shield walls are arranged on the upstream, the downstream and the side faces through sand bags, and the upstream face of the dam is constructed, specifically, a polystyrene board is fixed to the surface of the upstream face of the dam, plastic cloth is fixed to the upper portion of the polystyrene board, and the canvas is fixed to the plastic cloth; and the downstream face of the dam is constructed; By studying the performance and characteristics of various heat preservation materials, a theoretical basis is provided for formulating concrete wintering period protection measures, and on the premise that the engineering quality is guaranteed, the heat preservation measures are simplified, and the material cost is reduced.
本发明属于大坝混凝土施工领域，具体涉及一种高寒高海拔地区大坝混凝土越冬保温方法。大坝顶面施工：底部设置塑料布层，塑料布层上部设置橡塑海绵，橡塑海绵上部设置复合保温结构，该复合保温结构选用帆布；复合保温结构顶部采用钢管并按照3m×3m的网格连续压盖，同时上、下游和侧面用砂袋设置挡风墙，大坝上游面施工：大坝上游面表面固定聚苯板，聚苯板上部固定塑料布，塑料布固定帆布；大坝下游面施工；本发明通过研究各类保温材料的性能与特点，为混凝土越冬期保护措施的制定提供理论依据，在保证工程质量的前提下，简化保温措施并降低材料成本。
