工程废弃泥浆快速无害化处理研究

Study on Rapid and Harmless Treatment of Engineering Waste Slurry

工程废弃泥浆处理方法的选择需综合考虑项目需求、施工现场条件、工期、成本等,尤其是现场泥浆特性。随着城市的建筑密度逐渐增加,现场施工场地越来越小,化学处理方法具有的效率高、时间短、不占用施工场地等优点。以盾构施工和桩基施工产生的废弃泥浆为例,进行快速、无害化、固化处理试验研究,介绍了工程应用案例。

The selection of disposal methods of engineering waste mud should take into account the project requirements,construction site conditions,construction period,cost and so on,especially the characteristics of field mud.With the gradual increase of urban building density,the site construction site is becoming smaller and smaller.The advantages of chemical treatment methods are more obvious,such as high efficiency,short time and no occupancy of construction site.Taking the waste slurry produced by shield tunneling and pile foundation construction as an example,the experimental study on fast,harmless and solidified treatment is carried out,and engineering practice is introduced.
