Construction method for widening roadbed
The invention relates to the technical field of civil engineering, in particular to a roadbed widening construction method which is technically characterized by comprising the following steps: S1, dismantling and cleaning; S2, excavating the old road: after the old road is removed, excavating the old road part in a stepped manner, and paving geogrids, wherein the step-type excavation step comprises the steps that S21, the slope toe part of the old road is excavated, that is, the height of the lowermost layer of step is 1 m, the width of the lowermost layer of step is 2 m, and original ground treatment is conducted after leveling, S22, after original ground treatment is finished, a first layer of 60cm gun slag is filled, impacted and rolled, after soil is filled to the top of a first step,a slope in the middle of the old road is excavated, the size and width of the middle step are larger than or equal to 1m, and the height of the excavated step is the filling thickness; S23, during roadbed top layer construction, excavation is conducted on the side, close to an old road soil shoulder, of the roadbed top layer, and during the period, soil layer filling is impacted and rolled once every 1.5 m thick; and S3, soil filling roadbed construction is conducted, specifically, a cross section full-width and longitudinal and horizontal layered filling compaction method is adopted.
本申请涉及土木工程技术领域，具体涉及一种路基拼宽的施工方法，其技术要点在于包括以下步骤：S1、拆除清理；S2、老路开挖：清除完成后，进行老路部分的台阶式开挖，并铺设土工格栅；所述台阶式开挖步骤包括：S21、开挖老路坡脚部位，即最下面一层台阶高度为1m，宽度2m，整平后进行原地面处理；S22、原地面处理结束并进行第一层60cm炮渣填筑冲击碾压，填土至第一个台阶顶后，开挖老路中部边坡，中部台阶尺寸宽度≥1m，开挖台阶高度为填筑厚度；S23、路基顶层施工时靠近老路土路肩一侧开挖，期间土层填筑每1.5m厚冲击碾压一遍；S3、填土路基施工：采用横断面全宽、纵向水平分层填筑压实法。
