盾构机中心刀不同安装固定方式使用效果分析

ANALYSIS ON THE EFFECT OF DIFFERENT INSTALLATION AND FIXING METHODS OF CENTER KNIFE OF SHIELD MACHINE

随着地下空间的开发,采用盾构技术掘进隧道的方法已经建立并正在不断完善。复合盾构机的选型设计是盾构施工成败的关键,而刀盘选型设计又是盾构机选型设计最为关键的部件。不同的地层、不同的中心刀安装方式在盾构掘进中决定着盾构施工成败的关键。

With the development of underground space,the method of tunneling with shield tunneling technology has been established and is constantly improving.The type selection design of composite shield machine is the key to the success or failure of shield construction,and the type selection design of cutter head is the most critical part of the type selection design of shield machine.Different strata and different installation ways of the center knife determine the success or failure of shield construction.
