Description

Streckenausbau in Ring- oder Bogenform Der Gegenstand der Erfindung ist ein Streckenausbau in Ring- oder Bogenform mit in Abstand voneinander stehenden Ausbaurahmen von im Querschnitt keilförmiger Grundform, deren Keilschneide gegen das Gebirge gerichtet ist. Ein derartiger Streckenausbau ist bekannt. Bei dem bekannten Ausbau sind die Keilflächen gerade ausgebildet. Nach der Erfindung nimmt dagegen der Keilwinkel vom äußeren Umfang zum inneren Umfang allmählich oder stufenweise ab. Dadurch soll bei erhöhter Wirksamkeit und größerer Schonung der Keilschneide das Einschneiden der Ausbaurahmen in das Gebirge erleichtert und die Pressung, die beim Eindringen in das Gebirge auf den Ausbaurahmen wirkt, verringert werden. Wie der Querschnitt des Ausbaurahmens ausgebildet sein kann, ist beispielsweise in der Zeichnung dargestellt.Track extension in ring or arch form The object of the invention is a track extension in ring or arch form with spaced-apart extension frames with a wedge-shaped basic shape in cross-section, the wedge edge of which is directed towards the rock. Such a route expansion is known. In the known expansion, the wedge surfaces are straight. According to the invention the wedge angle from the outer periphery to the inner periphery on the other hand take t gradually or stepwise from. As a result, with increased effectiveness and greater protection of the wedge cutting edge, the cutting of the support frame into the rock is made easier and the pressure that acts on the support frame when it penetrates the rock is reduced. How the cross-section of the extension frame can be designed is shown, for example, in the drawing.
