摘要： PURPOSE:To directly perform shield excavation of a section set arbitrarily without depending upon outbreak made by a copy cutter by executing the excavation while setting tone section along with excavating forward. CONSTITUTION:The shield front is fitted with the first eccentrically driving drum 16 which is rotated in eccentricity from the shield center. The second eccentrically driving drum 26 to be rotated further in eccentricity from the rotational center of the first drum 16 is installed on its front. A cutter head 10 confronting the natural ground to be excavated is installed on the front of the second drum 26, and the two drums and this cutter head are arranged so as to be driven independently. The rotating position of the second drum is controlled in accordance with the rotating position of the first drum, and excavation of any desired section takes place.

摘要： PURPOSE:To effect a construction which is simple, accurate and of low cost by advancing downwards with a shield excavator, using existing shaft pipe bodies as guides, assembling segments consecutively at the rear end of the excavator and moving around the existing shaft pipe bodies. CONSTITUTION:A cutter head 10 is provided at the tip of a skin plate 9 which surrounds the circumference of shaft pipe bodies 4, and a clamping device 11 to the outer periphery of the pipe bodies 4 is connected to an end of a propelling jack 12. The other end of the propelling jack 12 is pin-connected to the rear part of the cutter head 10. Then, the periphery of the pipe bodies 4 is clamped by the clamping device 11, and the propelling jack 12 is extended and a shield excavator 8 is advanced. Then, the shield excavator 8 proceeds with excavation by the length of a stroke of the propelling jack 12, and the clamping device 11 is released, and the propelling jack 12 contracted. The clamping device 11 is pulled to wards the cutter head 10, and the pipe bodies 4 are again clamped and the excavator 8 proceeds with excavation. Thus, excavation is continued with the pipe bodies 4 being used as guides, and segments 20 that are lining materials are assembled in a consecutive order at the rear end and upward of the excavator 8.

摘要： PURPOSE:To enhance the efficiency of excavation work. CONSTITUTION:A shield jack 34 which drives a shield main body 12 is mounted to a jack support section 60 which is designed to move longitudinal with the shield main body 12 in a relative fashion. There is installed a reaction receiving device 66 which drives forward the jack support section 60 in the rear of the jack support section 60. The reaction receiving device 66 receives the reaction from a face section through the jack support section 60 during the shielding time of the shield main body 12 by the shield jack 34. At the same time, it forces the jack support section 60 to advances when the shielding drive of the shield main body 12 by the shield jack 34 has ended.
