Stuetzfluessigkeitsdruckregelung fuer eine Schildvortriebsmaschine |
摘要 |
<p>The digging tool of the tunnel excavator is mounted on a shield support and operates in a forward digging chamber. The digging chamber is sealed from a tunnel formed by the excavator by a separating wall of the excavator across a transverse cross section of the excavator. The digging chamber is filled with a fluid which supports the forward digging chamber wall. The problems resulting from the incompressibility of the supporting fluid can be handled simply when the digging chamber, with at least a portion of its separating wall, is supported so as to be movable longitudinally back and forth by an adjustable spring device. Advantageously, the spring device comprises a plurality of hydraulic cylinder devices whose cylinders are connected to a hydraulic accumulator under gas pressure.</p> |
