平寨水库大坝趾板段帷幕灌浆施工及灌浆效果分析

Curtain Grouting Construction and Grouting Effect Analysis of Pingzhai Reservoir Dam Toe Slab Section

大坝建设发展迅速,在大坝设计施工中,混凝土面板裂缝、接缝止水等问题较为常见,通过应用趾板段帷幕灌浆施工技术,能够有效提升平寨水库大坝施工质量。文章首先对大坝趾板段帷幕灌浆施工技术进行了介绍,然后以平寨水库大坝趾板段为研究对象,对帷幕灌浆施工要点以及灌浆效果进行详细探究。

The dam construction was developed quickly and it was common to cause fissure on concrete deck and juncture to stop water during the dam design construction. The application of curtain grouting construction technology on toe slab section can improve effectively the construction quality of Pingzhan reservoir dam. Firstly,this paper introduced the curtain grouting construction technology applied on the toe slab section,then,taking the toe slab section of the Pingzhai reservoir dam as the research object,to explore in details the construction key points of curtain grouting construction and grouting effects.
