Winter outdoor apron construction method
The invention discloses a winter outdoor apron construction method, and relates to the field of apron slope building construction. The method comprises the steps that hot-rolled ribbed steel bars are added after an apron foundation is tamped to form a bracket structure, the side face of a ground beam is chiseled, the bonding effect of concrete and the ground beam is improved, a bracket formwork is supported and poured, the bracket formwork is detached after 75% of strength is reached, the bracket lifting amount is small, and the supporting effect of the concrete formwork is improved; and backfilling, formwork supporting, pouring and heat preservation treatment are carried out on an apron area, the formwork is detached after the apron area is completely cured, and expansion joint construction is carried out. According to the method, the foundation cannot settle after a frozen soil layer is opened in summer during winter outdoor apron construction, the construction quality is guaranteed, and secondary repair construction is avoided.
本发明公开了一种冬季室外散水施工方法，涉及散水坡建筑施工领域。本发明通过在散水基础夯实后加入热轧带肋钢筋形成牛腿结构，对地梁侧面进行剔凿处理，增加混凝土与地梁的粘接效果，支护牛腿模板并进行浇筑，到达75%强度后拆除牛腿模板，牛腿提量小，提高了混凝土模板的支撑效果；对散水区域进行回填、支护模板、浇筑和保温处理，散水区域完全固化后拆除模板，进行伸缩缝施工。本发明提供的方法保证了冬季室外散水施工夏季冻土层开化后基础不会发生沉降，保障了施工质量，避免二次返修施工。
