泥水加压平衡盾构是20世纪70年代开发应用的密闭式盾构掘进机,它具有自动化程度高、开挖面稳定、掘进速度快等优点,成为当今国际上一种先进的盾构,并在日本、英国、德国等国家得到广泛的工程应用,比较典型的是日本东京湾道路工程9.2km双线隧道,就采用了8台φ14.14m泥水加压盾构。1 国内外泥水加压平衡盾构的泥水处理技术现状1.1 国外 Slurry pressure balancing shield is a closed shield boring machine developed and applied in the 1970s. It has the advantages of high degree of automation, stable excavation surface and fast excavation speed and has become an advanced shield in the world today. In Japan, the United Kingdom, Germany and other countries have a wide range of engineering applications, more typical of the Tokyo Bay Road, Japan 9.2km dual-lane tunnel, the use of 8 sets of φ14.14m mud pressure shield. 1 mud pressure balance shield at home and abroad mud water treatment technology status 1.1 foreign
