Abstract

The invention provides a doped construction waste integrated reinforced rib damping roadbed. The doped construction waste integrated reinforced rib damping roadbed comprises a cushion layer laid on the roadbed, a plurality of reinforced rib structural layers and roadbed fillers, wherein the reinforced rib structural layers are laid at intervals from bottom to top, and each reinforced rib structural layer comprises a plurality of waste plastic bottles, a two-way geogrid and reinforced rib structural fillers. The waste plastic bottles are bound to the two-way geogrid, the waste plastic bottles and gaps are filled with the reinforced rib structure fillers, the reinforced structural fillers is compacted in layers, and the reinforced structural fillers is a mixture of used tire chips and sand mixture which are blended according to the optimum mix proportion. The cushion layer and the roadbed fillers are both a mixture of construction waste and sand mixture. The bearing capacity and seismicperformance of the roadbed are improved, at the same time, inherent resources, namely, the construction waste, the waste plastic bottles and used tires are recycled and reused, the ecological environment is improved, the greenhouse effect is reduced, the cost is lower, and the doped construction waste integrated reinforced rib damping roadbed has a wide application prospect.

Description

technical field [0001] The invention relates to a shock-absorbing reinforced roadbed, in particular to a composite reinforced shock-absorbing roadbed doped with construction waste and a construction method. Background technique [0002] There are two major seismic belts in the world: the circum-Pacific seismic belt and the Mediterranean-Himalayan seismic belt. my country is exactly located between the circum-Pacific seismic belt and the Eurasian seismic belt, and is squeezed by the Pacific plate, the Indian plate and the Philippine Sea plate, and the seismic fault zone is very developed. From the perspective of geomechanics, China can be roughly divided into 20 seismic zones, which are characterized by high earthquake frequency, high intensity, and wide distribution of source lines. There are many shock-absorbing devices, although they have good shock-absorbing effects, they are often difficult to popularize in remote and earthquake-prone areas because of their high price, ...
