Construction process of urban main road
The invention discloses a construction process of an urban main road. The construction process comprises the steps of construction preparation, roadbed excavation, roadbed filling, embankment slope protection and pavement construction. The construction preparation process comprises the steps of determining an on-site working boundary line, survey and setting out and cleaning a site; the roadbed excavation process comprises the steps of excavating a base, trimming a slope of a subgrade bed and compacting the subgrade bed; the roadbed filling process comprises the steps of survey and setting out, base treatment, filling, soil filling and rolling compaction, filling and excavating joint part construction and fill section drainage; the embankment slope protection process is carried out, and grass planting protection is adopted when the height H of the embankment slope is less than or equal to 3m; when the height H of the embankment slope is greater than 3m, a mortar rubble framework is adopted for protection; a solid revetment is adopted in the fill pond section; the pavement construction process comprises the steps of laying a graded broken stone hardcore, constructing a cement stabilized broken stone base layer and constructing an asphalt concrete surface layer. According to the construction process, the overall stability of the road surface can be improved, and differential settlement is avoided.
本发明公开了一种城市主干道路的施工工艺，包括以下流程：施工准备、路基开挖、路基填筑、路堤边坡防护和路面施工；施工准备流程包括以下步骤：确定现场工作界线、测量放样和清理场地；路基开挖流程包括以下步骤：基底开挖、基床边坡修整和路床压实；路基填筑流程包括以下步骤：测量放样、基底处理、填筑、填土碾压、填挖结合部施工和填方段排水；进行路堤边坡防护流程，路堤边坡高度H≤3m时，采用植草防护；路堤边坡高度H＞3m时，采用浆砌片石骨架防护；填方水塘段采用实体护坡；路面施工流程包括以下步骤：级配碎石垫层铺设、水泥稳定碎石基层施工及沥青混凝土面层施工。本发明的施工工艺能提高路面的整体稳定性，避免产生不均匀沉降。
