摘要
阐述新加坡深水排污隧道DTSS2-T11项目,使用5台德国海瑞克φ4.3 m泥水盾构以及4套700 m^3/h的泥浆处理设备(HSP-700)建造了长12 km隧道。在设备使用过程中,通过改造设备提高了泥水处理设备(STP)在不同地层的处理效率。根据STP的现有问题,从STP工作状态、絮凝剂(PAC)和离心剂(Centrifuge)结合使用等方面进行了阐述。按照STP改造前、后为衡量准则,分析得出:采用各种改造方法,有助于STP的高效率运行,从而能在多变化地层的掘进过程中,起到参考和指导施工的作用。
It describes the DTSS2-T11 project of Singapore's deep water sewage tunnel,using 5 sets of German Herrenknecht slurry shield withφ4.3 mand 4 sets of mud treatment equipment(HSP-700)with 700 m3/h to construct a 12 km long tunnel.During the use of the equipment,the equipment is modified to improve the treatment efficiency of the STP in different formations.According to the existing problems of STP,the working status of STP and the combined use of PAC¢rifuge are explained.Based on the measurement criteria before&after STP transformation,the analysis concludes that the adoption of various transformation methods will help the high-efficiency operation of STP,so that it can serve as a reference&guide construction in the process of tunneling in changeable strata.
