Self-compacting cement soil widening roadbed and construction method
The invention provides a self-compacting cement soil widening roadbed and a construction method. The self-compacting cement soil widening roadbed comprises an old roadbed, a new roadbed, a throttlingbuilding block wall body and a roadbed surface layer, wherein the edge of one side to be widened of a cross section of the old roadbed is step-shaped; the throttling building block wall body is laid on the side, to be widened, of the old roadbed; the new roadbed is self-compacting cement soil filled between the one side to be widened of the old roadbed and the throttling building block wall body;the roadbed surface layer is paved on the top end surfaces of the old roadbed and the new roadbed; and top three-way geogrids are arranged between the top end surfaces of the old roadbed and the new roadbed and the roadbed surface layer. The connection between the edge of the old roadbed and the new roadbed is firmer, and differential settlement of the old roadbed and the new roadbed is prevented;and excavation spoil and engineering spoil are reasonably utilized, and resource high efficiency and environmental friendliness are achieved.
本发明提出一种自密实水泥土拼宽路基及施工方法，包括旧路基、新路基、节流砌块墙体和路基面层；所述旧路基横断面的待加宽一侧的边缘为台阶状；所述节流砌块墙体铺设在所述旧路基的待加宽一侧；所述新路基为填筑在旧路基待加宽一侧与节流砌块墙体之间的自密实水泥土；所述路基面层铺设于旧路基及新路基的顶部端面；所述旧路基及新路基的顶部端面与路基面层之间设置有顶部三向土工格栅。本发明的旧路基的边缘与新路基的连接更加牢固，防止旧路基与新路基不均匀沉降；合理利用开挖弃土、工程弃土，具有资源高效性、环境友好性。
