Construction method for foam concrete roadbed of expressway
The invention discloses a construction method for a foam concrete roadbed of an expressway. The construction method comprises the steps of construction lofting, step excavation, longitudinal and transverse blind ditch arrangement, formwork erecting, foam concrete preparation, pumping pouring, manual surface finishing and covering maintenance. Foam concrete is adopted for backfilling the roadbed, material preparation is simple, construction is conducted through piping pumping, the occupied space of construction is small, construction is convenient and fast, the construction period is short, the construction progress is accelerated, the construction period is shortened, labor input is reduced, the construction cost is reduced, and large economic benefits are generated; compared with a digging ash-doped backfill process, the foam concrete roadbed construction method does not need large equipment and lime, the digging ash-doped backfill construction period is 20 days, the foam concrete roadbed construction period is 10 days, and the efficiency is high. The gravel blind ditches can effectively drain seepage water in the roadbed out of the side slope, and it is guaranteed that the roadbed is stable and not affected by the internal seepage water.
本发明公开了一种高速公路泡沫混凝土路基施工方法，包括施工放样、台阶开挖、设置纵横向盲沟、支立模板、制备泡沫混凝土、泵送浇筑、人工收面、覆盖养生。本申请采用泡沫混凝土回填路基，材料制备简单，通过配管泵送施工，施工占用空间小，施工便捷、施工工期短，提升施工进度、节约工期，减少人工投入，降低施工成本，产生较大的经济效益；与翻挖掺灰回填工艺相比，泡沫混凝土路基施工工法不需要大型设备，不需要石灰，翻挖掺灰回填工期20d，采用泡沫混凝土路基工期10d，效率较高。碎石盲沟能有效地将路基内部渗水排除至边坡外，保证路基稳定不受内部渗水的影响。
