Abstract

Waist-round pipe jacking equipment is provided; stir teeth 1 and stir teeth 2 on a movable arm 1, stir teeth 1 and stir teeth 2 on a movable arm 3, stir teeth 1 and stir teeth 2 on a movable arm 2 and stir teeth 1 and stir teeth 2 on a movable arm 4 cut a soil body outside 5 drill bits and inside the four movable arms, and stir the soil body into slurry in relative and mutual motions; the slurry is discharged outside the pipe jacking through a slurry pump; the pipe jacking equipment forms a waist-round section in propulsion, and then a pipeline with a waist-round section follows the equipment one segment after another, thus forming a waist-round pipe jacking pipe; full section cutting is realized, so the pipe jacking has less resistance.

Description

technical field [0001] The invention relates to pipe jacking equipment, in particular to waist dome pipe jacking equipment used in pipe jacking engineering. Background technique [0002] At present, the waist dome pipe equipment used in the pipe jacking project is to cut the soil by one or more drilling heads to form an approximate waist circle section. Waist dome tubing is sometimes damaged during pressing in. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides a waist dome tube device. [0004] The present invention is achieved through the following technical solutions: [0005] A kind of waist dome pipe equipment, the outer ring of the master box is fixed to the waist shell through the partition plate, the right end of the master box is equipped with a motor, and the right end of the motor is fixed with a push rod; the left end of the master box is arranged side by side. Rod One, Drilling Rod Two, Drilling Rod Thr...
