Description

technical field [0001] The invention relates to a tunnel boring machine, in particular to a waist-shaped tunnel boring machine of a tunnel construction machine. Background technique [0002] At present, the tunnel excavator is completed by driving one or several circular cutterheads to rotate and cut. When several circular cutterheads rotate and cut, only an approximate waist-shaped section can be formed, and full-section excavation cannot be carried out. Contents of the invention [0003] The invention makes up for the above shortcomings of the tunnel boring machine and provides a waist-shaped tunnel boring machine. [0004] The present invention is achieved through the following technical solutions: [0005] A waist-shaped tunnel boring machine, with a first main cutterhead and a second main cutterhead arranged side by side, the first main cutterhead is driven to rotate by a first motor through a first power box and a first main shaft, and the second main cutterhead is ...
