4 泥水加压盾构图7为刀盘中心支承式泥水加压盾构示意图.图8则为周边支承式.不仅泥水加压盾构,各种带刀盘的盾构均有多种不同的刀盘支承方式.中心支承的特点是切削轮的中心轴既是心轴又是传动轴,支承简单,驱动方式也简单,易于维修和保养.缺点是占据了盾构的中心部份,导致作业空间减小,安装排碴装置
4 Slurry Pressure Shield Figure 7 shows a schematic diagram of a center-supported mud and water pressurization shield for the cutterhead. Figure 8 shows the surrounding support type. Not only the mud pressure shield but also all kinds of shields with cutterheads are different. Cutter plate support method. Center support is characterized in that the central axis of the cutting wheel is both the mandrel and the drive shaft. The support is simple, the drive mode is also simple, and it is easy to repair and maintain. The disadvantage is that it occupies the central part of the shield, resulting in the operating space.
