Pipe Umbrella System--Ground Engineering Fore Poling Technology.

JB Engineering Pipe Umbrella System is a pre-support measure used in weak ground conditions in conventional as well as mechanized Tunneling. Long fore poling using the pipe umbrella or canopy method is typically applied to increase safety and stability in the working area of standard advance operations, portals, and for re-excavating collapsed sections. Another application is ground improvement and waterproofing in combination with all tunnel construction methods.

JB Engineering Pipe umbrella pipes – installed into the ground prior to excavation – increase the stability in the working area by transferring loads in the longitudinal direction and decrease excavation induced deformations. JB Engineering has developed a superior pipe connection type, which allows the reduction of installation cycle times while increasing the load-bearing capacity. State-of-the art pipe umbrella support systems are installed self-drilling where the casing provides an immediate support of the borehole, compared to outdated pre-drilling systems where borehole drilling and pipe installation takes place in two different working steps.

Fully mechanized installation is becoming a mandatory safety standard in the global Tunneling business. JB Engineering is the leading system supplier in the development and application of safe and efficient pipe umbrella installation technology.

JB Engineering system comprises steel pipes installed from the tunnel face to form a roof to stabilize the tunnel headings. By distributing the load in longitudinal direction, it can decrease deformation during excavations.
