Construction method for solidifying shallow community road subgrade
The embodiment of the invention discloses a construction method for solidifying a shallow community road subgrade in the technical field of road engineering. The construction method for solidifying ashallow community road subgrade comprises the following steps: S1, surveying and setting out, namely, setting out an opening line of roadbed excavation by adopting a measurement control instrument according to a coordinate method and a filling and excavation width calculation method; S2, leveling a roadbed, namely, using a bulldozer, an excavator, a dumper and other machines to level the soil to be higher than a designed roadbed elevation according to the roadbed elevation of the design drawing; S3, spraying a liquid curing agent, namely, mixing the prepared curing agent to the curing layer ground by adopting a professional spraying and stirring machine, and performing cutting into the lower layer by 5-10mm to achieve lower layer connection; and S4, discharging pressure and striking off again, namely, after uniform mixing in the step S3, conducting primary shaping and fine shaping through a land leveler to achieve the specified flatness and road arch gradient. The construction method for solidifying a shallow community road subgrade with liquid has the advantages of improving the construction progress, ensuring the construction quality, reducing the construction cost, saving materials and the like.
本发明实施例公开了道路工程技术领域中的一种固化浅层小区道路路基施工方法。本发明的固化浅层小区道路路基施工方法，包括如下步骤：S1、测量放线；采用测量控制仪器根据坐标法和填挖宽度计算法，放样出路基挖方的开口线；S2、路床整平；根据设计图纸路床标高，采用推土机、挖机、自卸车等机械将土地形平整至高于设计路床标高；S3、喷洒液态固化剂；采用专业喷洒搅拌机械将配制好的固化剂拌合至固化层地面，并切入下层5‑10mm，达到下层联结；S4、排压再次刮平；在S3中拌合均匀后，通过平地机进行初整形和细整形，达到规定平整度和路拱坡度。本发明采用液体固化浅层小区道路路基施工工法具有提高施工进度、保证施工质量、降低工程造价、节约材料等优点。
