刀盘是盾构的主要工作部件,不同地质地层应采用不同的刀盘结构形式及刀具布置,刀盘及刀具的好坏关系到盾构施工的成败,影响盾构掘进的速度和效益,本文结合本标段盾构刀盘形式及刀具布置,浅谈对盾构刀盘的认识。
The cutterhead is the main working component of the shield. Different geological formation should adopt different structure of the cutterhead and the layout of the cutter. The quality of the cutterhead and the cutter is related to the success or failure of the shield construction and the speed and benefit of shield tunneling. Combined with the form of shield cutterhead and the layout of cutter, this paper briefly discusses the understanding of shield cutterhead.
