High fill roadbed construction method
The invention provides a high-fill roadbed construction method, and belongs to the technical field of roadbed construction technologies. The high-fill roadbed construction method comprises the steps that a soil body of a pre-fill road section is pretreated; the pretreated soil body is filled with phyllite to a first preset height, and then common ramming treatment is conducted; when the settlement of the soil body after the general ramming treatment meets an allowable value, filling and leveling a rammed pit and leveling an embankment; a geogrid is arranged on the embankment; and repeatedly filling phyllite on the geogrid to a designed height, and building a embankment slope surface and a side slope protection body. According to the high-fill roadbed construction method, local materials are used, phyllite of the highway, the abandoned tunnel and the mountain extension line is used as a filling material, the engineering investment of metamorphic rock transfer in related technologies can be reduced, and land occupation and adverse effects on the environment are reduced. And the time required for natural settlement of the soil body is shortened through common ramming operation, the working efficiency can be improved, and the time consumption of a filling project is shortened.
本发明提供了一种高填方路基施工方法，属于路基施工工艺技术领域，所述方法包括：对预填方路段土体进行预处理；在所述预处理后的土体上填筑千枚岩至第一预设高度后进行普夯处理；在所述普夯处理后所述土体沉降满足容许值时，填平夯坑并整平路堤；在所述路堤上设置土工格栅；在所述土工格栅上重复填筑千枚岩至设计高度，并，修筑路堤坡面及边坡防护体。本发明提供的高填方路基施工方法，就地取材将以高速公路、隧道弃方以及山体延线的千枚岩为填筑材料，可以减少相关技术中的转运变质岩的工程投资，减少土地占用和对环境的不良影响。并通过就普夯操作缩短土体自然沉降所需时间，可以提高工作效率，缩短填方工程耗时。
