GUIDED BORING, MICROTUNNELING, PIPE JACKING, SLIPLINING, & TUNNELING SOLUTIONS. Established in 1973, Akkerman develops, manufactures and supports advanced guided boring, microtunneling, pipe jacking, sliplining and tunneling underground construction solutions that accurately install 4-inch through 14-foot pipe diameters for a broad range of ground conditions and project challenges.
In computer networks, a tunneling protocol is a communications protocol that allows for the movement of data from one network to another. It involves allowing private network communications to be sent across a public network, such as the Internet, through a process called encapsulation.

Using Exceed X Server with SSH X11 Tunneling : This document explains how to set up the Hummingbird Exceed X Server and Secure CRT on your Windows personal computer and how to use them to display X-Windows output -- securely -- from icarus, or tigger, or from any other Unix machine that supports SSH X11 tunneling.
Meet our giant tunnelling machines. Digging the new tunnels was a 24-hour a day job, 7 days a week. Crossrail used eight tunnel boring machines (TBMs) to construct the new rail tunnels under London.
Linking cities with subterranean tunnels? Mining minerals thousands of feet below the Earth? No problem—engineers have spent more than two centuries designing and building monstrous machines for ...
GENERAL KNOWLEDGE ABOUT TBM TUNNELS . A typical rail tunnel section with its components . Schematic construction sequence for TBM . A shield machine at factory ready to transport out to the site
Understanding Microtunneling. Microtunneling is state of the art remote-controlled pipe jacking by computer, which is why we call it “Digital Age Tunneling”.
Instituted in 2015, the ITA Tunneling Awards recognize the most ground-breaking international innovation and outstanding projects in tunneling and underground space utilization.
A tunnelling shield is a protective structure used during the excavation of large, man-made tunnels.When excavating through ground that is soft, liquid, or otherwise unstable, there is a risk to workers and the project itself from falling materials and/or a cave-in.
KAMY series of Roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse or longitudinal cutter heads, these flexible machines can be used to excavate subway tunnels, road tunnels, railway tunnels and water tunnels without using explosives.
