Title: The Innovative Contributions of Adolf Foik
Introduction
Adolf Foik is a notable inventor based in Munich, Germany, recognized for his significant contributions to tunnel construction technology. With a total of six patents to his name, Foik has developed innovative methods and apparatuses that enhance the efficiency and safety of underground tunneling.
Latest Patents
Foik's latest patents include an "Apparatus for and a method of constructing a tunnel." This invention employs a drive shield composed of elongate drifting cutters arranged in a circular configuration around a support frame. Hydraulic rams are utilized to advance the cutters and shift the frame upward once all cutters have been advanced. The design features rear end portions of the cutters that engage with a follow-up ring behind the drive shield. Additionally, a platform supported by the frame within the shield carries a working appliance for detaching and removing debris material. It also includes a rotatable concrete spraying device that seals and secures the tunnel wall exposed when the follow-up ring is shifted up to the shield.
Another significant patent is the "Useful improvements in apparatus for, and in methods of, constructing a tunnel." This invention describes a tunnel driving apparatus and method that utilizes a drive shield made up of a series of cutter planks arranged side-by-side around the tunnel axis. The shield is advanced in relation to the frame by displacing the individual planks, while hydraulic rams draw the frame upward. A rear shield, connected to the frame through additional rams, supports the rear section of the tunnel wall. Lining elements of circular or arcuate form are installed inside the rear shield prior to its shifting up, allowing for fluid concrete to be sprayed over the exposed tunnel wall to consolidate the lining elements into the support lining.
