摘要： PURPOSE: To reduce the circumferential accumulated error in the assembling of segments to an extent that it does not bring a practical problem. CONSTITUTION: The mark of an assembling segment S1 and the standard marks of an existing ring are taken as images and the images are processed by an image processor to obtain the deviation between them. An operating quantity of an extending/contracting motion mechanism 11 of an erector body 10 to make the deviation zoro is obtained by an adjuster 21 of the deviation of marks in the erector control device 20. By taking the operating quantity into consideration, the extending or contracting motion mechanism 11 is operated in the cooperation with other motion mechanisms to make the mark of the assembling segment S1 coincide with the standard mark and complete the assembling.

摘要： PROBLEM TO BE SOLVED: To provide a branch-type propelling boring machine which can branch and start branched shield machines from a propelling boring machine, simplifies the structure of a branch portion thereof, and contributes to reduction in production cost, to thereby enable excavation of wide tunnel under a road or a river under which excavation of shafts is difficult. SOLUTION: The branch-type propelling boring machine is comprised of the propelling boring machine 1 and the plurality of branched shield machines which can be branched and started from the propelling boring machine 1 in directions orthogonal to a boring direction. The branched shield machines are simultaneously branched and started from a starting opening 6, and therefore the tunnel having a large cross section and a wide width can be efficiently drilled. When the boring is carried out by the propelling boring machine, the starting opening 6 is watertightly blocked with a gate 7, whereas the gate 7 is slid rearward at the time of branching and starting of the shield machines. Thus, the structure for branching and starting the shield machines is simplified, and therefore production costs of the machine is reduced. COPYRIGHT: (C)2003,JPO
