ABSTRACT:
An anchoring means for an earth works tunneling device includes a unit having two planar back-stop members secured together in spaced relation from one another. Between the back-stop members is provided a means for mounting the tunneling device so that a force exerted on the device is transmitted to the stop members. Thus, as the device drives or pulls a pipe or pipe stem through the earth, the counterreactive force is transmitted to one of the stop members which pushes against the adjacent earth bank so as to anchor the tunneling device.
