    Abstract:

    Vibrating boring and high-pressure jet grouting is an integrated technologies of drilling and grouting and advanced high-pressure jetting anti-seepage wall construction technology for one-step wall forming. Anti-seepage concretion was formed by punching shearing, mixing, lifting, replacing, packed pressing and permeable solidity with high-pressure jet flow. Fine silt dam by hydraulic filling was used in hydro-junction dam engineering for the first time, and high-pressure jetting anti-seepage wall was also for the first time used for seepage control. Large flow vibrating boring and high-pressure jet grouting is an innovation in high-pressure jet grouting technology, which can not only ensure construction quality but also increase working efficiency.
