摘要
长江中下游堤防存在着一定的隐患,以致洪水期易发生管涌等险情、垂直防渗墙新技术在除险加固工程中的应用,将使其防洪能力大为提高。在长江重要堤防隐蔽工程中应用的成墙技术主要有:薄壁抓斗成槽造墙、射水法成槽造墙、锯槽成墙、振动切槽造墙、振动沉槽防渗板墙、高喷灌浆造墙、多头小直径深层搅拌桩成墙、钢板桩防渗墙等。
There are some hided dangers in the downstream and middle reach of the Yangtze River so that the embankment there is subject to dangers of piping in flooding period. The application of the Vertical anti-seepage wall technology in danger elimination and consolidation project will greatly improve the flood control capacity. Main technologies to construct cutoff walls include thin-wall grabbing, water jetting, jetting in sessions, vibrating, high-pressure jet grouting, multiple-head and small diameter deep agitating pile and steel sheet pile and so on.
