Construction technology of shallow excavation pavement structure
The invention relates to a construction technology of a shallow excavation pavement structure, and belongs to the technical field of road structures, and the construction technology comprises the following steps: S1, selecting a site, excavating a foundation pit, cleaning earthwork in the foundation pit, and tamping a soil base at the bottom of a roadbed; s2, paving a cushion layer on the soil matrix, and rolling and leveling; s3, pouring a cement concrete layer on the cushion layer, and solidifying and forming the cement concrete layer; s4, paving the cement stabilized macadam base layer on the cement concrete layer, and rolling and leveling the cement stabilized macadam base layer; s5, paving a slurry seal layer on the cement stabilized macadam base layer and condensing the slurry seal layer; s6, paving an asphalt lower surface layer on the slurry seal and compacting the asphalt lower surface layer; and S7, paving an upper asphalt surface layer on the lower asphalt surface layer, and rolling and leveling the upper asphalt surface layer by using a road rolling device. The method has the advantages that the excavation depth of the foundation pit is reduced, the influence on existing underground pipelines is reduced, the excavation difficulty is lowered, and the construction efficiency is improved.
本申请涉及一种浅开挖路面结构的施工工艺，属于道路结构的技术领域，其包括以下步骤：S1、选择场地，并开挖基坑，清理基坑内土方并夯实路基底部土基；S2、将垫层摊铺在土基上并碾压整平；S3、在垫层上灌入水泥砼层并使其凝固成型；S4、将水泥稳定碎石基层摊铺在水泥砼层上并碾压整平；S5、在水泥稳定碎石基层上摊铺稀浆封层并使其凝结；S6、在稀浆封层上摊铺沥青下面层并压实；S7、在沥青下面层上摊铺沥青上面层并利用压路装置将其碾压整平。本申请具有减小基坑开挖深度、减小对现有地下管线的影响、降低开挖难度、提高施工效率的效果。
