    • A method and an apparatus for advancing cylindrical bodies. More than two underground cylindrical bodies are laid in longitudinal alignment with thrusting jacks disposed between them. A connecting member is arranged to pierce through them. A fastener is attached to one end of the connecting member while an advancing jack arrangement which has a removable-and-attachable fastener is attached to the other end of the connecting member. A suitable anchor body is disposed in front of the alignment of cylindrical bodies. Between the anchor body and each of the cylindrical bodies, there is provided a fixing member which pierces through them. Removable-and-attachable fasteners are disposed between the fixing member and the cylindrical bodies to interlink them for moving them forward underground one after another.
    • 一种用于推进圆柱体的方法和装置。 两个以上的地下圆柱体被放置成与它们之间布置的推压千斤顶纵向对齐。 连接构件被布置成刺穿它们。 紧固件附接到连接构件的一端,而具有可移除和可附接的紧固件的前进千斤顶装置附接到连接构件的另一端。 将适当的锚固体设置在圆柱体的对准之前。 在锚体和每个圆柱体之间,设有穿过它们的固定构件。 可拆卸和可附接的紧固件设置在固定构件和圆柱体之间,以将它们互连以将它们一个接一个地向前移动。
