Microtunnelling- und Schneckenbohrprojekte erfordern in der Regel Sch\u00e4chte (oder Gruben) an beiden Enden. Die Startgrube ist fast immer erforderlich und in den meisten F\u00e4llen muss auch eine Zielgrube vorbereitet werden. Diese St\u00fctzkonstruktionen m\u00fcssen vor Beginn der Tunnelbauarbeiten errichtet werden. Nach Fertigstellung der Kreuzung kann der Mikrotunnel oder der Bohrkopf im Empfangsschacht (oder in der Grube) geborgen werden.<\/p>\n

Je nach den hydrogeologischen Gegebenheiten des Standorts, der M\u00f6glichkeit, den Wasserzufluss zu kontrollieren, und den Umgebungsbedingungen wird eine von zwei Schachtkonfigurationen (oder Gruben) entworfen.<\/p>\n

Wenn das Tunnelling oder die Bohrarbeiten unterhalb des Grundwasserspiegels mit schwer zu bew\u00e4ltigenden Wasserzufl\u00fcssen stattfinden, empfiehlt sich der Bau wasserdichter Sch\u00e4chte.<\/p>\n

Es gibt drei Haupttypen von St\u00fctzkonstruktionen f\u00fcr wasserdichte Sch\u00e4chte, die alle Arbeiten in einer trockenen Umgebung unterhalb des Grundwasserspiegels erm\u00f6glichen und somit das Abpumpen von Wasser \u00fcberfl\u00fcssig machen:<\/p>\n

Nicht wasserdichte Sch\u00e4chte (oder Gruben) sind in der Regel weniger komplex. Ihre Hauptaufgabe besteht in der St\u00fctzung des umgebenden Bodens.<\/p>\n

Die oben genannten Bauweisen f\u00fcr Sch\u00e4chte (oder Gruben) k\u00f6nnen zwar auch verwendet werden. Allerdings f\u00fchren die damit verbundenen Kosten oft zu einem Einsatz von alternativen Techniken.

Im traditionellen Tunnelbau, bei denen die Ausgrabung von Arbeitenden an der Tunnelbrust durchgef\u00fchrt wird, die den Boden \u201emanuell\u201c ausheben und abtransportieren. Die g\u00e4ngigsten Methoden der Bodenabst\u00fctzung sind:<\/p>\n

Diese Art von Tunnel kann nur gebaut werden, wenn kein oder nur sehr wenig Wasser zu bew\u00e4ltigen ist, d.h. wenn die Aushubarbeiten oberhalb des Grundwasserspiegels oder in sehr undurchl\u00e4ssigen B\u00f6den wie Lehm oder festem Fels stattfinden.<\/p>\n

W\u00e4hrend der Tunnel gebaut wird, werden Metallb\u00f6gen installiert. Holzbalken (Bastaings) werden f\u00fcr die Abst\u00fctzung zwischen den B\u00f6gen verwendet.<\/p>\n

Diese Tunnel ben\u00f6tigen keine gro\u00dfe Baustelle, da weder an der Oberfl\u00e4che noch im Tunnel Maschinen zum Einsatz kommen. Es muss lediglich eine Bel\u00fcftungsanlage f\u00fcr die Arbeiten im Tunnel installiert werden.<\/p>\n

In der Regel handelt es sich um kurze L\u00e4ngen. Diese Technik kommt h\u00e4ufig in st\u00e4dtischen Gebieten zu Einsatz, wo die Dichte der bestehenden unterirdischen Netze den Einsatz mechanisierter Techniken verhindert. Dar\u00fcber hinaus ist es m\u00f6glich, den Tunnelverlauf entsprechend den an der Tunnelbrust entdeckten Netzen zu ver\u00e4ndern.<\/p>\n

Hierbei handelt es sich um eine halbmechanisierte Variante traditioneller Bohrtechniken. Der manuelle Aushub an der Tunnelbrust erfolgt wie bei holzausgesteiften Tunneln, jedoch wird die St\u00fctzung durch Stahl- oder Betonrohre gew\u00e4hrleistet, die mithilfe eines im Eingangsschacht installierten Schubsystems vorw\u00e4rtsgeschoben werden, w\u00e4hrend der Tunnel vorgeschoben wird.<\/p>\n

Daher ist die L\u00e4nge dieser Tunnel begrenzt, da der gesamte Tunnel auf einmal vorangetrieben werden muss, ohne dass eine Schmierung durch Mikrotunnelbohrmaschinen erfolgt.<\/p>\n
