Foam light soil bridgehead high fill roadbed and construction process thereof
The invention relates to the field of bridgehead fill roadbeds, and particularly discloses a foam light soil bridgehead high fill roadbed and a construction technology thereof.The foam light soil bridgehead high fill roadbed comprises an isolation layer and a foam light soil layer, and a protection wall is arranged in the foam light soil layer in a penetrating mode; the foam light soil layer is formed by pouring foam light soil, and the foam light soil comprises the following raw materials in parts by weight: 100 parts of Portland cement; 60 to 64 parts of water; 4 to 6.8 parts of foam; 21-35 parts of a modifier; the modifier is prepared from the following raw materials: a cationic polymer and improved soil, and the weight ratio of the cationic polymer to the improved soil is 1: (6-20). The construction process comprises the following steps: S1, excavating a roadbed and a side slope; s2, laying an isolating layer; s3, a stratum protection wall is poured; s4, foam light soil is poured; s5, maintenance is conducted; and S6, repeating the steps S3 to S5. The method has the effects of improving the pouring uniformity of the foam light soil and reducing the probability of differential settlement of the roadbed.
本申请涉及桥头填方路基领域，具体公开了一种泡沫轻质土桥头高填方路基及其施工工艺，泡沫轻质土桥头高填方路基包括隔离层和泡沫轻质土层，泡沫轻质土层内贯穿设置有防护墙；泡沫轻质土层由泡沫轻质土浇筑成型，泡沫轻质土包括以下重量份的原料：硅酸盐水泥100份；水60‑64份；泡沫4‑6.8份；改性剂21‑35份；改性剂的制备原料包括阳离子聚合物和改良土，阳离子聚合物和改良土重量比为1：（6‑20）。其施工工艺为：S1、开挖路床和边坡；S2、铺设隔离层；S3、浇筑地层防护墙；S4、浇筑泡沫轻质土；S5、养护；S6、重复S3‑S5。本申请具有提高泡沫轻质土浇筑均匀性，减小路基不均匀沉降的概率的效果。
