在长期的公路养护过程中,涵洞跳车是养护一大难题,此病害尤其在3级以下公路中最为突出。我们通过对跳车涵洞进行分析研究,采取切实可行的措施,较好地解决了这一难题。病害原因工程施工方面:没有按施工技术规范中的要求认真操作,在施工中填筑了不符合要求的土质,造成路基填土密实度不均匀和低于标准,路基抗压强度不够,在行车作用下产生沉降。涵洞洞顶和洞两侧一定范围内的路面强度低于原
In the long-term road maintenance process, culvert jumping is a major problem in the maintenance of the disease, especially in the following three road the most prominent. By analyzing and studying the culverts and taking practical measures, we solved this problem well. Disease causes Engineering construction: not in accordance with the requirements of the construction technology specifications serious operation, fill in the construction of substandard soil, resulting in uneven density of subgrade fill and below the standard, subgrade compressive strength is not enough, driving Under the action of sedimentation. Culverts and tunnels on both sides of the road within a certain range of intensity lower than the original
