冲填砂浆结石筑坝技术优势分析

冲填砂浆结石筑坝技术是对浆砌石筑坝技术的创新改进,它采用压力水泥浆冲砂,依靠砂浆的冲击力和重力作用填充已摊铺好的堆石体空隙实现筑坝。改进后的工艺使浆砌石施工过程的机械化程度得到提高,能够多级配综合利用粗骨料,节省人力资源和材料资源。介绍了冲填砂浆结石筑坝技术的工艺流程与使用的设备,并与浆砌石坝、堆石混凝土坝的施工技术进行对比,分析阐述冲填砂浆结石筑坝技术具有机械化程度高、工艺流程简单、施工速度快、自身防渗性能好、工程造价低、无需考虑温控等优势。

Analysis on Superiority of Stone Dam Construction Technique of Filling Slurry

Filli}ag slurry concretion damming technology is the innovation and improvement of stone masonry damming technology, which actually is filling cement paste into the inter-space of the rock-fill paved before by its impact force and gravity. The improved technology could im- prove the level of mechanization of mortar masonry and use multistage aggregate comprehensively, saving human and material resources. This paper introduced the technological process and apparatus utilized, made comparison with stone masonry damming technology and concrete damming technology and elaborated the advantages of stone dam construction technique of filling slurry, including high level of mechanization, simple technological process, fast speed of construction, good performance of anti-seepage, low project cost and none consideration of temperature control and so on.
