ISO2531 Standard Jacked Pipe Ductile Iron Wear Resistant For Steam
This kind of pipe is able to bear huge jacking pressure. As well
owns enough intensity to endure
internal and external pressure. It also possesses perect
characteristic of anti-corrosion and durability. In addition, the
inherent flexibility enables it to adapt ground displacement.
Pipe jacking is a trenchless method of new pipe installation
Factory made pipe sections are jacked or pushed behind the tunnel
boring machine or other tunnel excavation methods. Jacking force is
transmitted from thrust wall installed in the drive shaft. Pipe
jacking is used for the following cases.
1.Heavy traffic roads and crossing s of railways, rivers, and
2.Sensitive environment & neighborhood
The followings need to be considered when jacking is adopted.
1 High water table and difficult soil condition may require special
2 Jacked pipe may subside in soft ground.
3 H andling unexpected subsurface obstacles may face difficulties
4 Experience d operators and well organized construction work are
5 Location of shafts is important . Drive shaft may affect
Earth Pressure Balance
In closed earth pressure balance shield jacking, separation wall is
placed behind the cutter head of boring machine. Excavated soil
with or without plasticizer is filled between separation wall and
excavation face to stabilize the face. By controlling the amount of
excavated soil removed from the tunnel face, excavation and jacking
1. Good quality and low price.
