Powder solidified soil roadbed and construction method thereof
The invention discloses a powder solidified soil roadbed and a construction method thereof. The construction method comprises the following steps: mixing environment-friendly powder and cement according to a preset mass ratio to form dry powder; constructing a roadbed bottom layer of a soil body structure; spreading dry powder on the subgrade bottom layer to form a subgrade middle layer on the subgrade bottom layer; constructing a roadbed top layer of a soil body structure on the roadbed middle layer; fine leveling is conducted, specifically, the roadbed top layer is finely leveled through a land leveler to form the roadbed top layer with the flat surface; rolling, namely rolling the top layer of the roadbed downwards to form a dense powder solidified soil roadbed; and curing: the powder solidified soil roadbed is covered with geotechnical cloth for curing. The dry powder serves as the roadbed middle layer, the soil body characteristics of the roadbed bottom layer and the roadbed top layer are changed, the dry powder can be well combined with the roadbed bottom layer and the roadbed top layer, the water stop performance and the high pressure resistance of the formed powder solidified soil roadbed are improved, the construction efficiency can be improved, the maintenance period can be shortened, and the construction cost can be reduced; the energy-saving and environment-friendly effects are realized.
本发明公开一种粉剂固化土路基及其施工方法，包括：将环保型粉剂与水泥按预定质量比混合形成干粉剂；施工土体结构的路基底层；在路基底层上撒布干粉剂以在路基底层上形成路基中层；在路基中层上施工土体结构的路基顶层；精平：通过平地机对路基顶层进行精平形成表面平整的路基顶层；碾压：对路基顶层向下碾压以形成密实的粉剂固化土路基；养生：通过土工布覆盖粉剂固化土路基对其进行养生。本发明通过干粉剂作为路基中层，改变了路基底层和路基顶层的土体特性，能够使其与路基底层和路基顶层保持良好的结合，提高了形成的粉剂固化土路基的止水性能和抗高压性能，能够提高施工效率、缩短养护周期、降低工程造价，具有节能环保的效果。
