The Application of Solidified Fly Ash in Road Drainage Pipeline and Pipe Gallery Engineering
The groove width of road drainage pipeline and pipe gallery engineering is small,and it is difficult to backfill and compact with ordinary materials.In view of this,this paper summarizes the application advantages of solidified fly ash,and analyzes the variation law of its unconfined compressive strength with age.At the same time,taking a drainage pipeline and pipe gallery backfilling project as the research object,the construction quality control points of solidified fly ash backfilling are analyzed,and the application effect of solidified fly ash is evaluated from two aspects of compaction degree and compressive strength.The research results can provide reference for the backfilling of narrow pits and grooves.
