Settlement-preventing alternate-filling airport runway and construction method thereof
The invention discloses an anti-settlement alternate-filling airport runway and a construction method thereof, and relates to the technical field of airport construction. The anti-settlement alternate-filling airport runway comprises a roadbed and a surface layer, the surface layer is positioned on the roadbed; the roadbed structure comprises a solidified soil layer, a sand cushion layer, a gravel subbase layer and a composite reinforcing layer which are sequentially arranged on a pile-containing soil foundation from bottom to top, the composite reinforcing layer comprises a cement stabilizing layer and a novel geosynthetic material layer with a reinforcement function; the novel geosynthetic material layer comprises a geogrid; the geogrid material comprises a polypropylene composite material, and the polypropylene composite material comprises polypropylene and oily hydrophobic white carbon black. The anti-settlement alternate-filling airport runway provided by the invention has excellent long-term durable stability and safety, and the problem of uneven settlement of a foundation is effectively solved; and the construction method is simple and has high popularization value.
本发明公开了一种防沉降换填交替机场跑道及其施工方法，涉及机场建设技术领域。该防沉降换填交替机场跑道，包括路基和面层；所述面层位于路基之上；上述路基结构包括，在包含桩土基之上由下之上依次为固化土层、砂垫层、碎石底基层、复合加固层；上述复合加固层包括水泥稳定层和具有加筋作用的新型土工合成材料层；上述新型土工合成材料层包括土工格栅；上述土工格栅材料包括聚丙烯复合材料，上述聚丙烯复合材料包括聚丙烯和油性疏水白炭黑。本发明提供的防沉降换填交替机场跑道具有优异的长期耐久稳定性和安全性，有效解决地基不均匀沉降的问题；且施工方法简单，具有较高的推广价值。
