Construction waste resource filling method for road widening
The invention discloses a construction waste recycling filling method for road widening. The construction waste recycling filling method comprises the steps that a construction waste recycled aggregate concrete retaining wall is built on the outer side of an old roadbed slope; digging steps on the old roadbed slope to form a step surface; a filling area is formed between the construction waste recycled aggregate concrete retaining wall and the step surface; building waste regenerated filler is filled in the filling area in a layered mode, a layer of transverse rib material is laid after each layer is compacted, one end of each layer of transverse rib material is fixed to the step face, the other end of each layer of transverse rib material is stretched to the position of the building waste regenerated aggregate concrete retaining wall and then reversely wraps the building waste regenerated filler, and reversely-wrapped reinforced soil is formed; the process is repeated until filling is carried out below the pavement structure layer, and new roadbed filling is completed; and reinforcing anchor rods are connected between the construction waste recycled aggregate concrete retaining wall and each layer of reverse-wrapping reinforced soil. Compared with a traditional gravity type supporting and retaining structure, the supporting and retaining structure has the advantages of being good in anti-seismic performance, small in occupied area, wide in application range, high in construction efficiency, remarkable in economic benefit and the like.
本发明公开了一种道路拓宽用建筑垃圾资源化填筑方法，包括：在旧路基边坡外侧砌筑建筑垃圾再生集料混凝土挡墙；对旧路基边坡挖台阶，形成台阶面；建筑垃圾再生集料混凝土挡墙与台阶面之间形成填筑区域；在填筑区域内分层填筑建筑垃圾再生填料，并在每层压实后铺设一层横向筋材，每层横向筋材的一端固定在台阶面上，另一端拉伸至建筑垃圾再生集料混凝土挡墙处后对建筑垃圾再生填料进行反包，构成反包式加筋土；重复上述工艺，直至填筑至路面结构层以下，完成新路基填筑；在建筑垃圾再生集料混凝土挡墙与每层反包加筋土之间连接加固锚杆。本发明相较于传统重力式支挡结构，具有抗震性能好、占地少、适用范围广、施工效率高、经济效益显著等优点。
