Ф6840 mm土压平衡盾构机复合刀盘

Combined Cutter Head of Ф6840 mm Earth Pressure Balanced Shield

以Ф6840 mm土压平衡盾构机为例,介绍土压平衡盾构机刀盘的功能及组成,各种掘削刀具的结构和作用,指出刀盘设计的难点和重点。提出一种同时采用中心刀、滚刀、撕裂刀和刮刀的新的刀具布置形式,使刀盘的应用范围更广泛。

The paper takes Ф6840 mm earth pressure balanced shield for example to present the function and structure of the cutter head and point out the difficulties and key points on the design because it must hold various digging tools in different structures and functions.For this consideration,it puts forward a design of combined cutter head that can hold central,hob,tearing and scrapping cutters at same time on it for wider applications.
