Construction method for widening and transforming road foundation
The invention relates to a construction method for widening and transforming a road foundation, which comprises the following steps of: performing external expansion roadbed construction along the side edge of a widened roadbed section with the length side edge of a dry roadbed section larger than the length side edge of a wet and soft belt, designing a construction drawing, and comprehensively judging by considering the land occupation cost of external expansion demolition; and after roadbed widening construction is completed, bridge widening construction is conducted, and the ratio of lime volume to gravel volume to soil volume is 2: 2: 6 to serve as a backfill compaction material layer between the dry soil layer and the lower bottom face of the widened subbase layer. Original roadbed and bridge widening does not need open circuit construction, the land area occupied by external expansion can be reduced, the construction cost is reduced, and the construction efficiency and widening quality are improved.
本发明涉及一种加宽改造道路基础的施工方法，包括如下步骤，沿干燥路基段长度侧边大于湿软带长度侧边的加宽路基地段侧边进行外扩路基施工,设计施工图，且考虑外扩拆迁占地成本综合判断，先对路基加宽施工，路基加宽施工完成后再进行桥梁加宽施工，用石灰体积：碎石体积：土体积为2：2：6作为干土层至加宽底基层下底面之间的回填压实料层等。本发明对原有路基和桥梁加宽无需断路施工，能减少外扩占用土地面积、降低施工成本、提高施工效率和加宽质量。
