PROBLEM TO BE SOLVED: To provide an underground-joining shield machine which is relatively simple in structure, low in manufacturing cost, good in working efficiency, and has a skin plate for ensuring water cutoff. SOLUTION: The underground-joining shield machine consists of a receiving shield machine (1) and a penetrating shield machine (30) which carry out tunnel excavation in two directions to be joined to each other. The penetrating shield machine (30) has a cutter section and the skin plate (40) arranged on a front section thereof. The receiving shield machine (1) has a joining device (14) arranged in a front inner section of a trunk (2) thereof, for accommodating therein the skin plate (40), and a tube seal (26) arranged inside the joining device. Further the receiving shield machine has an inner trunk (4) and a hardener injection pipe arranged inside the trunk (2). The inner trunk functions to bear the cutter section at its front section and is reciprocatively movable. When the shield machine is at a joint location, the skin plate (40) is joined to the joining device (14) and the tube seal (26) is pressurized to cut off water, followed by injecting the hardener (43) via the injection pipe.
