Expressway reconstruction and extension project construction process
The invention discloses an expressway reconstruction and extension project construction process, and relates to the technical field of road reconstruction, and the expressway reconstruction and extension project construction process comprises the following steps: step 1, road surface cleaning; step 2, road surface marking; 3, foundation pit excavation is conducted, specifically, foundation pits are excavated in the two sides of the original expressway correspondingly according to the road surface lineation positions; 4, pile foundation construction is conducted, specifically, a plurality of prefabricated pile foundations are driven into the bottom of the foundation pit, and the top ends of the pile foundations are 0.5-1 m higher than the bottom of the foundation pit; step 5, tamping; sixthly, a leveling layer is constructed, the top face of the leveling layer is lower than the pavement of the original expressway, and the top ends of the pile foundations are embedded in the leveling layer; and step 7, paving an asphalt pavement, and after the pavement of the asphalt pavement is finished, leveling with the pavement of the original expressway. The method has the advantages that after the expressway is reconstructed and expanded, the splicing position between the new road and the old road is not prone to high error position, longitudinal cracking, bulging and the like, and then the overall engineering quality after the expressway is reconstructed and expanded is guaranteed.
本申请公开了一种高速公路改扩建工程施工工艺，涉及道路改造的技术领域，其包括步骤1、路面清理；步骤2、路面划线；步骤3、基坑开挖，根据路面划线的位置，在原有高速公路的两侧分别开挖好基坑；步骤4、桩基施工，将若干预制好的桩基分别打入基坑的底部，且桩基的顶端高出基坑底部0.5‑1m；步骤5、夯实；步骤6、找平层施工，找平层的顶面低于原有的高速公路的路面，桩基的顶端嵌设于找平层内；步骤7、沥青路面铺设，沥青路面铺设完成后，与原有高速公路的路面齐平。本申请具有在对高速公路进行改扩建后，新老路之间的拼接部位不易出现高差错位、纵向开裂、鼓包等情况，进而保证高速公路改扩建后的整体工程质量的效果。
