Lightweight filler roadbed construction method and structure of river-side soft soil roadbed widening section
The invention provides a construction method and structure for a light filler roadbed of a riverside soft soil roadbed widening road section, and belongs to the technical field of roadbed construction. According to the method, small square piles are arranged below a retaining structure breast board foundation on the side, close to a river, of an embankment, are prefabricated in a concentrated mode through a professional prefabricating yard, are transported to the site and are driven into a foundation one by one according to the designed position, a soft soil foundation is compacted, and a foundation compaction zone is formed to surround a roadbed area; then a light reinforced concrete breast board structure is arranged on the edge of a road shoulder of the spliced wide road section along the river side, a pile head of the small square pile is anchored into a breast board foundation structure and forms a whole with a breast board foundation, steps are excavated at the original roadbed slope line, and after a layer of slag is backfilled on the inner side of a light breast board, the small square pile head and the breast board foundation form a whole; the rest roadbed height is completely filled with light foam concrete to the roadbed, and a layer of reinforced concrete slab is arranged on the top face of the foam concrete to serve as an underlying supporting layer of the pavement structure. The problems that a traditional construction method is large in processing work amount, high in manufacturing cost, complex in procedure, slow in construction progress and the like are solved.
本发明提供一种沿河软土路基拼宽路段轻质填料路基施工方法及结构，属于路基施工技术领域。该方法是在路堤靠河一侧支挡结构挡土板基础下设置小方桩，小方桩由专业预制场集中预制，运至现场，逐根按设计位置打入地基中，对软土地基进行挤密，形成地基挤密带包围路基区域，再在沿河侧拼宽路段路肩边缘设置轻型钢筋混凝土挡土板结构，小方桩桩头锚入挡土板基础结构中，与挡土板基础形成整体，原路基边坡线处开挖台阶，轻型挡土板内侧在回填一层宕渣后，剩余路基高度全部采用轻质泡沫混凝土填充至路床，泡沫混凝土顶面再设置一层钢筋混凝土板，作为路面结构的下卧支撑层。以解决传统施工方法处理工程量大、造价高、工序复杂、施工进度慢等问题。
