Artificial filling island airport runway structure and construction method thereof
The invention discloses an artificial filling island airport runway structure and a construction method thereof. The pavement structure is sequentially provided with a wearing layer, a geocell solidification layer, a geocell coral sand mattress layer and a long and short pile composite foundation layer from top to bottom. The geocell solidification layer is formed by filling a geocell with solidifiable cement coral sand; the geocell coral sand mattress layer is formed by filling and blow-filling coral sand in a geocell; coral sand dredger fill is used as a material, ordinary Portland cement and water are used as a curing agent, and the materials are mechanically stirred to form a flow-state curable mixture with certain fluidity. Compared with a traditional artificial island reef runway construction technology, the airport runway constructed through the method has the advantages of being small in post-construction settlement and differential settlement, low in construction cost, short in construction period, free of cracking of the runway surface, long in service life, high in blast damage resistance and the like.
本发明公开了一种人工填筑岛礁机场跑道结构及其施工方法，该道面结构由上而下依次设置为磨耗层、土工格室固化层、土工格室珊瑚砂褥垫层和长短桩复合地基层；所述土工格室固化层为在土木格室内填充可固化水泥珊瑚砂构成；所述土工格室珊瑚砂褥垫层为土工格室内填充吹填珊瑚砂构成；可固化水泥珊瑚砂是以珊瑚砂吹填土为材料、固化剂普通硅酸盐水泥和水，经过机械搅拌形成具有一定流动性的流态可固化拌合物。与人工岛礁传统跑道建设技术相比较，利用本发明建造的机场跑道具有工后沉降及差异沉降小、施工造价低、工期短、道面不开裂、服役寿命长、抗爆毁能力强等优点。
