Abstract

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.

Description

technical field [0001] The invention relates to the technical field of road widening, in particular to a construction waste resource filling method for road widening. Background technique [0002] With the development of social economy and the increase of traffic flow, some original roads in our country can no longer meet the development and needs of modern transportation, and the widening and reconstruction of roads has become a hot issue in the field of transportation. [0003] In the widening and reconstruction of existing highways, how to achieve a good combination of new and old subgrades and reduce or even eliminate differential settlement while occupying as little land resources as possible is a key issue in road widening treatment. Due to the limitations of design methods, construction machinery performance and construction technology, traditional methods often set gravity retaining structures on the outside of the road. This method has high requirements on the bear...
