影响高等级公路质量的因素中路基沉降所占比例较高,对路基进行注浆加固,与其他工艺相比,明显具有成本低、施工简便、见效快、对交通影响少等优点,路基注浆施工还可以作为一种有效的预防性维修措施,对路面路基早期出现的預见性病害进行及时的处理,大大延长路面的使用寿命。本文介绍了路基注浆加固的施工方法以及质量检验标准。 Affect the quality of high-grade highway factors in the settlement of a higher proportion of roadbed for grouting reinforcement, compared with other processes, obviously low cost, construction is simple, quick, traffic less advantages, roadbed grouting The construction can also be used as an effective preventive maintenance measure to deal with the predicted diseases appearing at the early stage of the roadbed timely and greatly extend the service life of the road surface. This article introduces the construction method of subgrade grouting reinforcement and the quality inspection standard.
