Self-compacting rock-fill concrete construction process
The invention discloses a self-compacting rock-fill concrete construction process. The process comprises the following steps that 1, a foundation bin surface is treated, wherein firstly, loose rock blocks, sundries, soil and the like are removed, thorough flushing is carried out, no accumulated water exists, then roughing is carried out through a high-pressure water gun, and finally roughening iscarried out through an electric pneumatic pick; 2, a formwork is installed, wherein before formwork engineering construction, the geometric dimension is firstly designed according to the engineering structure, the strength, rigidity and stability should be ensured by formwork supporting, and the formwork is formed by combining a steel formwork and bamboo plywood; and 3, rock filling is carried out, wherein rock-fill materials are stacked when the strength of the concrete reaches 2.5 MPa or above. According to the process, the construction defects caused by the situation that construction operators are lack of subjective experience in the traditional vibrating compaction construction process can be remarkably reduced and even avoided; the technical problem that vibrating compaction construction of a complex structure is difficult can be solved; and rock-fill gaps are filled by means of self weight, so that concrete with a high stone content is formed.
本发明公开了一种自密实堆石混凝土施工工艺，包括以下步骤：步骤1：基础仓面处理；首先清除松动块石，杂物、泥土等，冲洗干净且无积水，然后通过高压水枪进行冲毛，最后电风镐凿毛；步骤2：安装模板；模板工程施工前先根据工程结构设计几何尺寸，模板支护应确保强度、刚度、稳定性，模板采用钢模板和竹胶板相结合；步骤3：堆石；在混凝土强度达到2.5MPa以上时，进行堆石料堆码；本发明可显著减少甚至避免传统振捣密实施工过程中因施工操作人员主观经验欠缺而导致的施工缺陷；可解决复杂结构振捣密实施工困难等技术难题；依靠自重，填注堆石空隙，形成的一种高含石量的混凝土。
