Summary:pipe jacking machine
The basic principle of pipe jacking construction:
Side jacking excavation formation, pipe burying method of the long pipeline.
According to the pipe diameter size of the jacking points: large, medium caliber, small aperture and miniature jacking pipe four. 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. Division of jacking distance there is no clearly defined, the past is about 100m pipe. At present, the pipe jacking has It is often seen. km above, can be 500m above the pipe jacking is called the long distance pipe jacking.
According to the type of pipe jacking machine: hand dug type manual pipe jacking, extrusion pipe, water jet pipe and pipe jacking machine (slurry, mud, soil type, rock type).
1.Slurry balanced pipe jacking machine
Slurry balance pipe jacking machine refers to the use of mechanical cutting soil, to balance the water pressure and earth pressure, slurry pipe jacking machine adopts hydraulic conveyance spoil by pressure, pipe jacking machine is a kind of advanced modern production.
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.
