Large diameter of phi 2m above the pipe jacking, people can walk upright in them. Medium caliber jacking pipe diameter is 1.2 ~ 1.8m, in which people walk stoop, most pipe jacking in diameter pipe jacking. Small caliber pipe diameter of 500 ~ 1000mm, in which people can only crawl, sometimes even crawling are difficult. Miniature jacking pipe diameter is below 400mm, the minimum is only 75mm.
According to a top length (between jacking working pit and receiving pit distance): ordinary distance pipe jacking and long distance pipe jacking.

Slurry balance pipe jacking machine according to the balanced object is divided into two kinds, one is water only balance the action of groundwater, soil pressure is balanced by mechanical means; another is also has the balance of groundwater pressure and soil pressure.
2.earth pressure balance pipe jacking
machine
Earth pressure balance pipe jacking machine consists of EPB shield
machine transplanted, the balance principle and shield the same. Compared with
the slurry pipe jacking construction, the biggest feature is discharged from the
soil or mud generally do not need to be treated two times, has the cutting
excavation of soil, the soil pressure balance, the disturbance of soil, ground
and building small small settlement etc..
According to the filling of clay
soil chamber type earth pressure balance pipe jacking machine, soil type, slurry
type and mixed type three; according to the cutter head form panel, with knife
disc and no panel cutter disc; according to whether the mudding function, common
type and mudding type; from the mechanical transmission a square cutter disc
type, a center transmission type, transmission center and peripheral
transmission type; according to the cutter much, a single disc and cutter
disc.
