Title: Innovations by Volker Hentschel in Tunnel Lining Technology
Introduction
Volker Hentschel is a notable inventor based in Dorsten, Germany, recognized for his contributions to tunnel lining technology. With a total of 11 patents to his name, Hentschel has developed innovative solutions that enhance the efficiency and effectiveness of concrete placement in tunnel construction.
Latest Patents
Hentschel's latest patents include a "Form for Concrete-Placement Tunnel Lining" and a "Process and Apparatus for Lining a Tunnel with Concrete." The form for concrete tunnel lining is designed to be used behind a tunnel excavator with a traveling shield. It consists of an inner tunnel-lining sheathing divided into multiple segments that can move independently, allowing for flexibility during the construction process. The form front, positioned between the traveling shield and the inner sheathing, is designed to move forward as concrete is pressed into the annular space, ensuring a smooth and efficient lining process.
The process for lining a tunnel involves forcing concrete between the surrounding geological structure and the inner tunnel-lining form. This is achieved through a form front that moves sealingly against both the outer surface of the inner form and the inner surface of the shield. The design includes a hydraulic spring device that balances friction forces, ensuring optimal performance during the concrete feed interruptions.
