在隧道防水工程施工中,存在隧道内渗漏水的现象,这主要是由于多年来,在低温条件下隧道产生冻害的原因,隧道防水注浆施工工程是有效加固隧道围岩、治理渗漏水的有效措施,但是,由于冻胀力、施工温度、材料的耐低温性能等各种因素,隧道工程的防水注浆施工技术有更高的要求,考虑到低温条件下隧道工程注浆机理,则需要采用与常温下施工差异较大的防水注浆施工技术,来达到理想的效果。
In the tunnel waterproofing construction, there is the phenomenon of seepage in the tunnel, which is mainly due to the reason that the tunnel is frozen under low temperature for many years. The tunnel waterproof grouting construction project is effective to reinforce the tunnel surrounding rock and treat the seepage water However, due to various factors such as frost heaving force, construction temperature and low temperature resistance of materials, waterproof grouting construction technology of tunnel project has higher requirements. Considering the grouting mechanism of tunnel engineering under low temperature condition, Need to adopt the waterproof grouting construction technology with large difference in construction at room temperature, to achieve the desired effect.
