Construction method of self-compacting concrete rock-fill dam
The invention relates to a construction method of a self-compacting concrete rock-fill dam. The construction method of the self-compacting concrete rock-fill dam comprises the following steps of S1, forming a dam face, S2, conveying hewn block stone to the dam and warehousing; S3, pumping self-compacting concrete to the dam; and S4, conducting pouring and warehousing of the self-compacting concrete. By means of optimization on multiple dimensions such as a rock filling manner, stone particle size control, concrete water-binder ratio control and a grouting method, self-compacting filling of concrete can be completed without the need for adding a grouting pipe in the whole construction process; and in the whole process, conveyance, rock filling and grouting all can be completed through mechanical equipment without insertion and arrangement of the grouting pipe and accurate pouring to the grouting pipe, concrete in a rock-fill body is high in flow rate and rapid in diffusion, and therefore the construction efficiency of the rock-fill dam is greatly improved.
本发明涉及一种自密实混凝土堆石坝施工方法，包括如下步骤：S1坝面成型；S2毛块石上坝入仓；S3自密实混凝土泵送上坝：步骤S4自密实混凝土的浇筑入仓。本发明通过对堆石方式、石材粒径控制、混凝土水胶比控制、灌浆方法等多个维度进行优化，使得整个施工整个过程中无需添加灌浆管即可完成混凝土的自密实填充，过程中无论是运输、堆石还是浇灌，都可以通过机械设备完成，且少了灌浆管的插布和对灌浆管的精准浇筑，堆石体内混凝土的流动率高、扩散快，大幅度提高堆石坝施工效率。
