Tunnel boring machine (TBM) cutterhead and shield jamming processing method

The invention discloses a tunnel boring machine (TBM) cutterhead and shield jamming processing method. The method comprises the following steps that (1) a longitudinal small pilot tunnel is excavated; (2) a plurality of annular small pilot tunnels are excavated along the longitudinal small pilot tunnel; (3) supporting and reinforcing are conducted through a steel structure; and (4) a TBM slowly tunnels and passes through a fault zone. The method has the advantages of being fast and convenient to implement, small in number of construction steps, safe and reliable. The method is adopted to conduct release operation on a cutterhead and a shield of the TBM, operation is safe, and the jammed cutterhead and a jammed shield machine of the TBM can be released in an extremely short time, so that cost is reduced, and time is shortened. 本发明公开了种TBM刀盘和护盾卡机处理方法，所述方法包括如下步骤：（1）、开挖纵向小导洞；（2）、沿纵向小导洞开挖若干环形小导洞；（3）、通过钢结构进行支护和加固；（4）、TBM缓慢掘进通过断层带。本发明具有快速方便、施工步骤少、安全可靠的优点，采用该方法对TBM的刀盘和护盾进行脱困处理，不但操作安全，而且还能够在极短的时间内将被卡的TBM刀盘和护盾机进行脱困，节约了成
