Abstract

The invention discloses a rounded triangular pipe-jacking tunneling machine. A first driving box, a second driving box and a third driving box drive three stirring rods to drive three stirring heads to rotate respectively in an operation process, wherein the three stirring heads are arranged at the lower ends of the stirring rods which are arranged at the lower ends of the three driving boxes respectively. Three rotating shafts rotate to drive cutters to rotate through connection arms respectively. Three stirring heads rotate to cut a soil mass behind into three holes in triangular lap joint, the cutters on the three rotating shafts rotate to cut soil on three sides of the similar triangular hole structure and mix the cut soil with water to form slurry, and the slurry is discharged outside a jacking pipe by a slurry pump. The pipe-jacking tunneling machine propels to form the rounded triangular hole structure, and then pipelines of a rounded triangular section form a long-distance rounded triangular jacking pipeline step by step.

Description

technical field [0001] The invention relates to a pipe jacking machine, in particular to a rounded triangle pipe jacking machine used in pipe jacking engineering. Background technique [0002] At present, the rounded triangle pipe jacking machines used in pipe jacking projects all use one or more mixing heads to rotate and cut the soil to form an approximately triangular section, and the rounded triangle pipe jacking pipe has a large resistance during the pressing process. Contents of the invention [0003] The present invention makes up for the above disadvantages and provides a full-section excavation rounded triangular pipe jacking machine. [0004] The present invention is achieved through the following technical solutions: [0005] A round-cornered triangular pipe jacking machine, the partition board divides the pipe jacking machine into the mud tank at the back and the working cabin at the front, the periphery of the partition is fixed on the triangular shell, and t...
