浅谈大直径泥水平衡盾构施工泥水处理系统应用及固废循环利用

Discussion on application of slurry treatment system and solid waste recycling of large diameter slurry shield construction

结合杭州某隧道工程,介绍了大直径泥水平衡盾构施工泥浆处理系统的设备选型、运行效果评估等,重点分析了隧址地层的岩土工程特性、分离渣土的产生数量预测、泥水处理系统设备性能和实际使用效果,提出了基于岩土工程分析进行渣土生成数量预测,进而选择泥水处理系统设备的思路,并对今后泥水处理系统应用的经济效益及相应的固废循环利用的实施前景作了展望。

Based on a tunnel engineering in Hangzhou,this paper introduces the equipment selection,operation effect evaluation of the slurry separation system for tunnelling by large diameter slurry shield machines.The geotechnical properties of the tunnel site stratum,prediction of the quantity of separated waste soil,equipment performance of the slurry treatment system and its actual application effects were analysed in detail.The importance of predicting the quantity of separated waste soil based on geotechnical engineering analysis for the selection of the slurry treatment system equipment is proposed.And the economic benefits of the slurry treatment system and the prospects of relevant solid waste recycling are looked forward.
