Self-compacting rock-fill concrete construction method
The invention discloses a self-compacting rock-fill concrete construction method, and relates to the technical field of mass concrete. The construction method of the self-compacting rock-fill concrete comprises the following steps: treating a foundation surface; feeding the rough block stones into a basic surface in the bin to form a rock-fill body with gaps; and self-compacting concrete is fed into the bin and poured on the rock-fill body. Construction is completed only through the two working procedures of rockfill warehousing and self-compacting concrete pouring, and the construction technology is simple; a large amount of rubble is used, and the use proportion of the rubble can reach 55%-60%, so that the use amount of the concrete is greatly reduced, the hydration heat in the concrete solidification process is reduced, temperature control measures can be simplified or even canceled according to the actual temperature condition on site, the vibrating procedure is omitted in the pouring process, the production efficiency is further improved, and the production cost is reduced. And the construction period is shortened, and the investment of labor cost is reduced.
本申请公开了一种自密实堆石混凝土施工方法，涉及大体积混凝土技术领域。该自密实堆石混凝土施工方法，包括：基础面处理；将毛块石送入仓内的基础面上形成有空隙的堆石体；将自密实混凝土送入仓内浇筑在堆石体上。本申请仅采用堆石入仓和自密实混凝土浇筑两道工序完成施工，施工工艺简单；本申请还大量使用了毛块石，其使用比例可高达55％～60％，这样不仅大大减少了混凝土的用量，降低了混凝土凝固过程中的水化热，根据现场实际温度情况可简化甚至取消温控措施，而且浇筑过程中免去了振捣工序，进一步提高了生产效率，缩短了施工工期，还减少了人工成本的投入。
