SCHILDVORTRIEBSMASCHINE

摘要

The shield driving machine has a dividing wall sealing off the space for the cutting disc in a pressure-tight manner. A conveying means can be attached to the dividing wall in a pressure-tight manner via a connection piece. The attachment point contains a non-return valve which can be opened by pushing in the conveying means and automatically closes when the conveying means is pulled back. Level-measuring devices for detecting the fluid level are arranged inside the housing of the conveying means, compressed air being injected via a line into the housing of the conveying means if a maximum fluid level is exceeded.
