Roadbed widening method
The invention discloses a roadbed widening method, relates to the field of highway construction, and solves the problems of differential settlement of new and old roadbeds, poor durability and great influence of construction waste on the environment in the prior art. The method comprises the steps that the sheet piles are driven to the embedding depth, an original roadbed is excavated, and the reinforcing anchor rods are driven; l-shaped panels are placed, and internal geocells are laid; placing the L-shaped panel on the uppermost layer; tensioning operation is conducted on the pre-stressed anchor rod, and after tensioning is completed, the fixed end of the pre-stressed anchor rod is locked; and a surface geocell is laid, and construction of the widened roadbed structure is completed. The method can be used for widening construction of roads.
本发明公开了一种路基的加宽方法，涉及公路施工的领域，解决了现有技术中新老路基的差异沉降、耐久性差、建筑垃圾对环境影响较大的问题。该方法包括板桩打入至嵌入深度，开挖原路基，打入加强锚杆；摆放L型面板，铺设内部土工格室；摆放最上层的L型面板；对预应力锚杆进行张拉作业，待张拉完成后，对预应力锚杆的固定端进行锁定；铺设表层土工格室，完成加宽路基结构的施工。本发明可用于道路的加宽施工。
