Description

technical field [0001] The invention relates to a pipe jacking main engine, in particular to a rectangular pipe jacking main engine used in pipe jacking engineering. Background technique [0002] At present, the square pipe jacking used in pipe jacking construction is made of multiple circular cutterheads to form an approximate rectangle. There are many places in the rectangular section that the circular cutterheads cannot excavate, and it is very difficult to jack the pipe. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides a rectangular pipe jacking main machine. [0004] The present invention is achieved through the following technical solutions: [0005] A rectangular pipe jacking main engine, the support body is set in the middle of the pipe jacking, the support body is connected with a curved beam ② downward, the lower end of the curved beam ② is fixed with a shaft plate ①, and the left part of the shaft plate ①...
