Embodiment Construction
[0041] Such as figure 1 The one shown is suitable for conditions where the ground where the shield machine stops is relatively loose, the self-stabilization ability of the soil on the tunnel surface is poor, and there are structures directly above the cutter head. The shield machine cannot use the four methods commonly used in China at present ( For details, refer to the content recorded in the background technology part) when performing a tool change, the shield machine tool change construction method for tunnel construction is characterized in that the method includes the following steps:
[0042] Step 1. Replacement and filling of the soil bin: use the screw excavator 2 and the grouting system that works synchronously with the screw excavator 2 to replace and fill the soil bin. The screw excavator 2 is installed on the side wall of the soil bin 1 in the shield machine 6 The lower part, the grouting system is installed on the upper part of the side wall of the soil bin 1, an...
