基于U形肥槽的预拌流态固化再生混合料回填技术应用研究

RESEARCH ON THE APPLICATION OF BACKFILLING TECHNOLOGY OF READY-MIXED FLUID SOLIDIFICATION RECYCLED MIXTURE BASED ON U-SHAPED FERTILIZER TANK

近年来,各类工程项目的类型愈发复杂,对肥槽回填的要求也越来越高,针对不同形状、不同要求的肥槽,以往采用的素土、灰土、砂石等常规材料已经无法满足使用功能。以丰台医院提质改建项目为例,针对项目U形肥槽使用流态固化土材料代替常规回填土进行研究探索,并针对预拌流态固化再生混合料回填施工工艺进行阐述,以供类似工程参考。

In recent years, the types of various engineering projects have become more and more complex,and the requirements for backfilling of fertilizer troughs have become higher and higher. For fertilizer troughs of different shapes and requirements, we used plain soil, lime soil, sand and gravel in the past. Conventional materials have been unable to meet the function of use. This paper takes the quality improvement and reconstruction project of Fengtai Hospital as an example, researches and explores the use of fluidized solidified soil material instead of conventional backfill soil for the U-shaped fertilizer tank of the project, and expounds the construction process of ready-mixed fluidized solidified recycled mixture backfill for similar projects. to reference.
