渗透灌浆即藉助于灌浆压力 ,浆液克服各种阻力渗入孔隙或裂隙 ,就地凝固而达到加固或减少渗漏的灌浆方法。理论上假定在灌浆过程中地层结构不受干扰和破坏。也即浆液渗入土孔隙 ,排除土中的自由水与空气 ,而不破坏其原有结构。本文介绍了一渗透灌浆在既有建筑物地基加固中的应用实例。 Penetration grouting refers to the method of grouting that reinforces or reduces leakage by means of grouting pressure, which overcomes various resistances to infiltrate into pores or cracks and solidifies in situ. It is theoretically assumed that the formation structure is not disturbed and destroyed during the grouting process. That is, the slurry penetrates into the pores of the soil and removes free water and air from the soil without destroying its original structure. This article describes an example of penetration grouting in the foundation reinforcement of existing buildings.
