TBM cutter head for shaped charge blasting auxiliary tunneling

The TBM cutterhead comprises a cutterhead body and an energy-gathered blasting device, a through hole is formed in the cutterhead body, and the energy-gathered blasting device is fixed in the through hole; wherein the shaped charge blasting device blasts to enable the tunnel face rock mass to generate a cutting groove, and the integrity of the tunnel face rock mass is destroyed. According to the energy-gathered blasting device, blasting can be conducted while tunneling is conducted, when the energy-gathered blasting device works, grooving can be conducted on a tunnel face rock mass, the integrity of the tunnel face rock mass is broken, rock mass stress on the tunnel face is released, tunneling of a TBM main body cutterhead is facilitated, and the TBM tunneling speed can be effectively increased during hard rock tunneling. 本发明公开了一种聚能爆破辅助掘进的TBM刀盘，包括刀盘盘体以及聚能爆破装置，其中，在刀盘盘体上开设通孔，聚能爆破装置固定在通孔中；其中，聚能爆破装置爆破能使掌子面岩体产生切槽，破坏掌子面岩体的整体性。本发明可边掘进便爆破，聚能爆破装置工作时可对掌子面岩体切槽，破环掌子面岩体的完整性，释放掌子面上的岩体应力，以便于TBM主体刀盘的掘进，在硬岩掘进时，可有效增加TBM掘进速率。
