摘　　要：在大伙房输水隧洞工程施工中成功拓展的"全孔一次高压注(HSC)浆技术",从工艺上吸纳了"常规分段注(水泥)浆技术"和非常规的"纯压式全孔一次高压注浆技术"的优点,采用了HSC特种注浆材料,是一种新的超前预注浆技术,施工效率高,可控性、可灌性优异,注浆效果显著,具有明显的经济性。The “full hole high-pressure grouting（HSC）” successfully developed during the construction of Dahuofang Water Di- version Project is a new pre-grouting technology, which adopts a new special grouting material-HSC and absorbs the merits from both the conventional “stage grouting（cement） ” and the unconventional “full hole pure-pressure grouting”. The technology has the advantages of higher construction efficiency, good controllability and groutability, prominent grouting effect and better economics as well.
