Study On Technical Parameters And Construction Technology Of Construction Waste Recycling Material Treatment Of Wet Soft Loess Foundation

With the speeding up of urbanization process,the production of construction waste, cause serious environmental pollution and waste of space resources. The reasonable use of construction waste,and corresponds to the highway engineering huge material demand, not only solved the pollution to the environment and sustainable development of resources, and alleviate the road with the lack of material.Referring to existing research results and engineering examples, initially worked out a set of laboratory research program, aimed at understanding the basic road construction of the waste recycled performance and on wet of loess foundation treatment of the disposal of the results.In this paper, based on the south highway construction project of Lanzhou city, through the basic physics experiment, studies the basic physical and mechanical properties of construction waste and draw the corresponding indicators. On different mixture ratio of construction waste specimens large compression experiment instrument and unconfined compressive strength test, obtains the construction waste recycled material of granular material and cementation material best ratio.Secondly, according to the similarity theory, design the corresponding indoor model test,the construction waste reworked material in the form of a medium materials and recycled concrete pile used in collapsible loess foundation, and the working condition of two kinds of type and under the condition of different pile spacing, the settlement of composite foundation deformation law.In addition, the use of numerical simulation software. The foundation of model,according to the corresponding engineering input soil parameters, load gravity load. Analysis of recycled material treated wet soft loess foundation consolidation settlement etc. the main process of change.
