Construction method of rock-fill concrete adopting concrete with shear thinning characteristic
The invention relates to a rock-fill concrete construction method adopting concrete with the shear thinning characteristic. The rock-fill concrete construction method comprises the steps that a formwork is built on a to-be-poured bin face to form a bin position; the bin face comprises a functional area, and the bin position is filled with rockfill materials to form a rockfill area with the preset height. Self-compacting concrete with the shear thinning characteristic is poured into the functional area in a mode of multiple times of pumping layering till the pouring height of the self-compacting concrete with the shear thinning characteristic in the functional area is the same as the preset height of the rock filling area; and common self-compacting concrete is poured into the rock filling area, so that the common self-compacting concrete is in direct contact with the self-compacting concrete with the shear thinning characteristic. By adopting the self-compacting concrete with the shear thinning characteristic, the construction procedure can be simplified, and the construction quality can be improved.
本申请涉及一种采用剪切稀化特性混凝土的堆石混凝土的施工方法，包括：在待浇筑的仓面上搭建模板以形成仓位；所述仓面包括功能区，将堆石料填筑在所述仓位中以形成具有预设高度的堆石区；采用泵送分层多次的方式将具有剪切稀化特性的自密实混凝土浇筑在所述功能区，直至所述功能区内的具有剪切稀化特性的自密实混凝土浇筑高度与所述堆石区的所述预设高度相同；以及将普通自密实混凝土浇筑在所述堆石区，使得所述普通自密实混凝土与所述剪切稀化特性的自密实混凝土直接接触。本申请采用具有剪切稀化特性的自密实混凝土能够简化施工程序，提高施工质量。
