Roadbed and inspection well differential settlement control construction method
The invention relates to a roadbed and inspection well differential settlement control construction method, and belongs to the technical field of road construction. The roadbed and inspection well differential settlement control construction method comprises the following steps of (1) roadbed filling: digging slopes into ladder shapes, and carrying out layered filling and dense grinding according to the varieties of soil; (2) pipe channel construction: setting one water collecting well, digging a pipe channel to designed elevation, stably placing pipelines, and performing a pipeline leakproofness closed water test for once after the construction of a section of pipeline is completed every time; (3) inspection well construction: tamping a foundation soil layer of the inspection well by adopting a pounder, and then carrying out foundation construction of a cushion layer and reinforced concrete; (4) backfilling: backfilling the pipeline channel by adopting medium-coarse sand, and compacting in layers; backfilling the periphery of the inspection well by adopting aggregate and dust or sand; (5) roadbed top surface construction: densely grinding by adopting a vibrating type road roller of which the weight is more than 12t until the surface has no obvious wheelmarks. According to the roadbed and inspection well differential settlement control construction method disclosed by the invention, the roadbed is compact, the roadbed is stably matched with the pipelines and the inspection well, and the inspection well is not easy to collapse.
