Domestic garbage incinerated ash and mixed soil composite reinforced subgrade and construction method thereof

Abstract

The invention discloses a domestic garbage incinerated ash and mixed soil composite reinforced subgrade. The domestic garbage incinerated ash and mixed soil composite reinforced subgrade comprises a foundation layer, a subgrade layer paved on the top surface of the foundation layer and a road surface layer paved on the top surface of the subgrade layer, wherein the subgrade layer comprises a subgrade base body and a plurality of layers of reinforced structure layers; the subgrade base body is prepared from compacted filler and the filler is mainly prepared by mixing domestic garbage incinerated ash and clay; the reinforced structure layers are paved in the subgrade base body at intervals from bottom to top; the reinforced structure layer on the topmost layer is located on the bottom surface of the road surface layer; each reinforced structure layer is mainly composed of a geogrid and a geocell fixed at the top of the geogrid. According to the domestic garbage incinerated ash and mixedsoil composite reinforced subgrade disclosed by the invention, the urban domestic garbage incinerated ash is used as a filler component to be applied to subgrade construction, so that the environmentpollution is reduced, the land occupation problem caused by accumulation of garbage ash is alleviated and a novel way is provided for harmless and reclamation treatment on the ash; the domestic garbage incinerated ash and mixed soil composite reinforced subgrade disclosed by the invention has excellent strength and rigidity.

Description

technical field [0001] The invention relates to a reinforced roadbed structure in geotechnical engineering, in particular to a composite reinforced roadbed with domestic waste incineration ash and slag mixed soil and a construction method thereof. Background technique [0002] With the rapid development of my country's economic construction and the improvement of people's living standards, more and more domestic garbage is produced in cities. To dispose of these garbage, incineration is a more effective method for reducing the amount of garbage. However, a large amount of incineration ash remaining after incineration also needs to be disposed of. At present, most of our country adopts landfill disposal, which is not conducive to the resource utilization of waste. The ash in incineration ash has high utilization value, and its physical, chemical and engineering properties are similar to natural aggregates. It is a waste to landfill it, which is not conducive to the resource u...
