摘要： PURPOSE:To make the manufacture of a two-throw shield excavator easier as well as reduce the cost of manufacture by using a simple structure in which two machines are connected in parallel, one front cylinder is bent to the rear cylinder and advanced while being turned through the other cylinder. CONSTITUTION:Cutters 4 are attached to the frong sides of a shield excavator 2 having a front cylinder 2a and a rear cylinder 2b which are separated from each other, which is integrated with a shield excavator 3, in such a way as to enable both the machines 2 and 3 in a relatively turable manner by the connecting pin. The front cylinder 2a of the excavator 2 is bendably set by a bending mechanism to the rear cylinder 2b. when the front cylinder 2a is bent and advanced, the excavator 2 is advanced through the excavator 3 advancing straight forwards by difference in the excavating directions of the excavators 2 and 3. A two-throw shield tunnel having a spiral form is constructed around the tunnel by the excavator 3 by means of the first excavator 2. In this case, the tunnel can be obtained by using the conventional tapers and the conventional straight segments.

摘要： PURPOSE:To make it possible to cope with the alteration of the state of a tunnel section by making each of shield segment lining sections as a circular single section structure in which an inside hollow section is separated from the peripheral surfaces, and laying an elastic body between the lining sections. CONSTITUTION:After two circular single section segments 10 are extruded by laying a solidified elastic body 11 between them, grout 12 is filled into a gap between the peripheral bedrock and the segments. Two shield segment lining sections 13 are arranged in parallel through the elastic body 11, and horizontal twin shield tunnels separated from each other, whose inner peripheries are circles and whose outer peripheries are generally circles, or vertical twin shield tunnels are constructed. Specially, in the case a double-section shield excavator 1 is used, such shield tunnels that change from the horizontal twin tunnels to skew twin ones and to the vertical twin ones or to the reverse can be easily constructed. According to the constitution, the segments 10 can be easily manufactured and assembled, the cost can be reduced, and the work efficiency can be promoted.

摘要： PROBLEM TO BE SOLVED: To provide an inner unit for a small diameter curved line propulsive construction which is used in the small diameter curved propulsive construction by burying many propulsive pipes connected so as to be bent in a bore formed for constructing an underground curved line sewage pipe to form the bore while feeding or discharging sludge, is good in stability upon rolling and restoration characteristics and is effectively formed in a ultra-micro structure without a leakage and an action of unreasonable force. SOLUTION: The inner unit 1 housed in the propulsive pipe 2 inserted into the formed bore comprises a travel pipe 3 which a robot using a new optical fiber ultra-micro sensor enters and a support plate 4 for elastically supporting it on a protruding arcuate surface so as to roll, guide roller members 5, 5 and 6 provided at right and left parts and a vertically lower end of the support plate 4 to come into contact with lower parts in the inner surface of the propulsive pipe 2 and hold the inner unit at a lower center of gravity position, and a sludge feed pipe 7 or a sludge discharge pipe 8. A section is extremely made compact, that is, about 1/10 as large as a usual section. A construction cost is lower by about 40% than a usual cost so that an innovative large effect can be obtained.

摘要： PURPOSE:To improve workability by providing a plural number of rotary cutters having clearances in the peripheral direction at specified relative positions on a front end of a shield outer shell of a double row circular arc section and arranging expansible enlarged drilling heads coaxially on the clearance parts. CONSTITUTION:A plural number of rotary cutters 2 forming a clearance part 2a in the peripheral direction are provided on the same flat surface on a front end part of a shield outer shell l arranged vertically by way of overlapping parts of a plural number of cylinders. Thereafter, drilling heads 4 to expand and contract in the diametrical direction are arranged coaxially with the cutters 2 in the clearance 2a while the cutters 2 make a center 01 of the outer shell 1 as their rotational center and make their outer periphery contact with a joining line (a) connecting a contracted part 1a. Thereafter, in case of drilling, a circular part is drilled by the cutters 2 and extensively drilled by advancing and retreating the heads 4 by computer control. In case of branching, a branch tunnel having a rectilineal horizontal part on a circular lower part is drilled by drilling by way of dividing the cutters on the joining line (a). Consequently, it is possible to carry out drilling efficiently without wasteful drilling and to easily branch.

摘要： PROBLEM TO BE SOLVED: To develop a micro robot to be used in a small-diameter pipe for reducing construction costs, shortening terms of works, and substantially rectifying such defects that a curved introduction pipe made of steel and having a personal computer arithmetic function incorporated inside has contributed to very high construction costs and long terms of works in conventional constructions of underground, curved, and small-diameter sewer pipes. SOLUTION: A compact inner unit is used instead of a conventional curved introduction pipe. A conventionally cylindrical pipe for the travel of a robot is rectangularly formed to minimize rolling and improve measurement accuracy. A gyroscope newly using a triaxial optical fiber is mounted inside of a new type micro robot carriage, and the carriage is towed to travel through the pipe for the travel of a robot by a new towing device. Angles measured by the gyroscope or measurement elements of independently measured positions are transmitted to an external personal computer difference from before and computed and measured in the system of the micro robot carriage.

摘要： PROBLEM TO BE SOLVED: To develop and provide a rational and innovative small-bore pipe jacking method for a bore of 70 cm or less, which lowers a cost of and shortens a period of construction, by an automatic surveying system using a robot or the like, and by an automatic construction system. SOLUTION: An expensive curved induction pipe made of steel is eliminated, and a very small robot using an advanced optical fiber gyro is adopted. A small inner unit suitable for construction work on a curved part is developed. A conventional track having a circular cross section and often causing rolling errors of a measuring instrument is abandoned and a track for the robot is formed in a square cross section to enhance measurement accuracy. A slurry is supplied, and a slurry discharging pipe for discharging the slurry by an excavator is provided in the inner unit. A novel sewage pipe installation method for the small bore, long distance pipe including a curve by one process is disclosed. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent the interference between disks and improve the advance efficiency by making at least one cutter disk movable in the longitudinal direction against a front drum in a fold type shield machine provided with multiple cutter disks. SOLUTION: When a folding jack 5 is operated for the rolling or direction change of the whole shield machine 1, cutter disks 9A, 9B are moved in the longitudinal direction so that no interference occurs between a shield drum 3 and the cutter disks 9A, 9B. When the shield machine 1 is straightly advanced, the longitudinal interval CL1 between the cutter disks 9A, 9B is reduced to the utmost possible to improve the stability of the working face, the cutter disks 9A, 9B are overlapped into a cocoon shape or a potbelly shape, and the overbreak area is reduced to the utmost. The cutter disks 9A, 9B are inclined in opposite directions centering on a pivotal support pin 8, the shield machine 1 is turned in a spiral shape, and the direction can be changed vertically or horizontally. The advance efficiency can be improved.
