摘要： PROBLEM TO BE SOLVED: To easily and firmly join existing and new tunnels together. SOLUTION: A cutting and reinforcing ring 6 is provided inside the skin plate 2 of a shield machine 1 in such a way as to be free to move back and forth in the excavating direction, and a ring driving jack 10 for pushing out the cutting and reinforcing ring 6 is provided on the ring 6. As a new tunnel T2 is excavated using the shield machine 1, the cutting and reinforcing ring 6 is pushed out by the ring driving jack 10 at a position a predetermined distance away from an existing tunnel T1, after which the cutting and reinforcing ring 6 is pushed out while being rotated by transmitting the driving force of a cutter 11. The segments of the existing tunnel T1 are cut using a cutting bit 7 to form openings so as to join the existing T1 and new T2 tunnels together.

摘要： PROBLEM TO BE SOLVED: To prevent a water cut-off means from coming into contact with the cut surface of an existing segment in the rotating condition to be damaged and make a designated limited installation range suffice in the case of advancing a ring to cut and intrude into an existing segment to be joined to the segment, thereby joining a new tunnel and an existin tunnel to each other and installing a water cut-off means comprising a water cut-off bag or the like in the outer periphery of the ring. SOLUTION: A ring joined to an existing segment comprises a cutting ring 4 which is positioned inside a skin plate 2 and turned to cut and intrude into a segment 13 of an existing tunnel and a water cut-off ring 3 which is positioned outside the cut ring 4, not rotated and provided with a water cut-off container 10 as a water cut-off means on the outer periphery thereof, which is adapted to cut off water in a gap between the intruded cut ring 4 and the cut-opened existing segment 13. While being rotated, the cut ring 4 is advanced to cut and intrude into the segment 13 of the existing tunnel and joined thereto, the water cut-off ring 3 is advanced in synchronization with the cut ring 4 without rotation to make the water cut-off container 10 closely adhere to the cut opening surface of the segment 13.

摘要： PROBLEM TO BE SOLVED: To provide a shield tunnel joining method by which even in the case where a new shield tunnel is joined to the side surface of an existing shield tunnel, the soil improvement can be reduced or eliminated without being restricted by the working site, and the reinforcing materials in the vicinity of the opening part of the existing segment can be reduced, and in the case of the slide hood system even the gravel ground or the like difficult in sliding can be smoothly excavated, so that it can be securely and inexpensively joined in a prescribed position. SOLUTION: A shield excavator 2 for constructing a new tunnel is approached to a joining place, and a pipe for pipe roofing is excavatedly inserted from the shield excavator 2 so as to reach the inside of an existing tunnel 8a. These pipes are arranged at given intervals in the outer circumferential part of the hollow section inside the new tunnel so as to form a pipe roof.

摘要： PROBLEM TO BE SOLVED: To easily and surely execute joint between an existing tunnel and a new tunnel. SOLUTION: Ring driving jacks 11 for pushing out a cut/reinforced ring 6 are provided to the cutting-reinforcing ring 6 provided to the inside of a skin plate 2 of a shield excavator 1 in a retractable manner and, at the same time, interlocking grooves extended in constant length in the direction of excavation are formed in the inside circumferences of them. Expansion cutters 17 are fitted into the interlocking grooves to transfer rotational driving force of a cutter 14 to the cutting-reinforcing ring 6. The existing tunnel T1 is connected to a new tunnel T2 by pushing out the cutting-reinforcing ring 6 with the ring driving jacks 11 by providing extrusion rings 12 and extrusion rods 13 between the cutting-reinforcing ring 6 and ring driving jacks 11, 11,... while rotating the cutting-reinforcing ring 6 by transferring driving force of the cutter 14.

摘要： PROBLEM TO BE SOLVED: To secure safety and to reduce construction period by laying two almost triangular special segments one on the other with their base sides facing their outer peripheries, and cutting and removing the principal part of the base through the cutting of unreinforced concrete using a shield machine. SOLUTION: Unreinforced concrete 4b is placed on the surface of one side of a base 4a of steel or reinforced concrete to construct a special segment 4 almost in the form or a triangle. Two special segments 4 are used as a pair and, when a first shield tunnel 1 is being constructed, the base 4a is placed upright and connected to upper and lower portions. In that case, time circular surface of the unreinforced concrete 4b of one segment is incorporated flush with the outer peripheral surface of the other segment 4. Next, as a second shield tunnel 2 is constructed, excavation is performed, and the excavating blade of a shield machine 3 is stopped immediately before making contact with the base 4a. Only a predetermined area of the base 4a is cut and removed from the inside of the first shield tunnel 1 to open a joint, then secondary lining is performed on the joint, and the tunnels 1, 2 are joined together at their crossing parts.

摘要： PROBLEM TO BE SOLVED: To increase the excavation distance by improving the durability of a cutter bit as a whole. SOLUTION: The excavator includes a cutter disk 2A, in which a large number of cutter bits 8 are raclially arranged in rows, at the forward end of a cylindrical shield body, and while the cutter disk 2A is being rotated about the center axis thereof, the shield body is pushed forward to excavate the ground. In this case, a small disk 5 having a center of rotation parallel to the center axis of the disk 2A is disposed at approximately the middle point of the radius of the disk 2A and the cutter bits 8 are arranged in rows on the disk 5 in the diametrical direction thereof.

摘要： PURPOSE:To adjust the humidity of stored coal, etc. and keep the quality of said coal, etc. constant by installing a roof which is movable along a longitudinal direction between a pair of structures which form the side walls of a storage area, and moving said roof in accordance with weather. CONSTITUTION:Coal C is unloaded from a transport ship 30 and, after being carried into the storing area A of a stock yard 1 by means of unloaders 32 and conveyors 33, 34 stored in pipes by means of stacker reclaimers 35 and a reclaimer 36. When it is raining or in a season when the direct rays of the sun are hard, a roof 9 is moved in the longitudinal direction of fences 3 by means of a driving device to adjust the humidity of the coal C in a defined storage area B which is to be transferred into a group of silos 38 next. On the other hand, when the coal C is overly dried, water is sprinkled on the coal C by means of sprinklers 37 to adjust its humidity adequately. In sensors of good weather, the roof 9 covering the defined storage area B is removed to hasten the drying of the coal C by the aid of open air.
