Deep soft soil high filling roadbed widening structure and construction method thereof
The invention discloses a deep soft soil high filling roadbed widening structure and a construction method thereof.The deep soft soil high filling roadbed widening structure comprises an original roadbed, a slope is cut along the slope line of the original roadbed, a plurality of steps are dug, and a foam concrete bottom plate is arranged on the first step face close to a soft soil layer; the outer edge of the foam concrete bottom plate is connected with a concrete side wall plate vertically arranged on the first step surface, foam light soil is poured in an area defined by the concrete side wall plate and the steps to form an expanded roadbed, and a pavement structure layer is laid on the surface of the original roadbed; the steps are excavated on the side slope line of the original roadbed, so that the stability of connection between the original roadbed and the expanded roadbed is improved, the phenomenon of transverse cracking of the widened expanded roadbed is avoided, differential settlement of the new roadbed and the old roadbed can be effectively reduced, and the roadbed is high in overall strength, high in construction flexibility and wide in application range.
本申请公开了一种深厚软土高填路基加宽结构及其施工方法，包括原始路基，沿所述原始路基边坡线削坡并挖设数级台阶，在靠近软土层的第一级台阶面上设置泡沫混凝土底板，所述泡沫混凝土底板的外缘连接垂设于所述第一台阶面上的混凝土侧墙板，在所述混凝土侧墙板与数级所述台阶所围成的区域浇筑泡沫轻质土形成拓展路基，在所述原始路基表面铺设路面结构层；本申请通过在原始路基边坡线开挖台阶提高原始路基和拓展路基之间连接的稳固性，避免加宽的拓展路基出现横向开裂现象，可有效减少新旧路基不均匀沉降，路基整体强度高，施工灵活度高、适用范围广。
