固化粉煤灰在道路排水管道及管廊工程中的应用

The Application of Solidified Fly Ash in Road Drainage Pipeline and Pipe Gallery Engineering

道路排水管道及管廊工程的沟槽宽度小,采用普通材料难以回填密实。鉴于此,文章总结了固化粉煤灰的应用优势,分析了其无侧限抗压强度随龄期的变化规律。同时,以某排水管道和管廊回填工程为研究对象,分析了固化粉煤灰回填的施工质量控制要点,从压实度和抗压强度两方面对固化粉煤灰应用效果进行评价,研究成果可为狭窄坑槽的回填提供参考。

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.
