摘要： PROBLEM TO BE SOLVED: To reduce the device in size and shorten the thawing days by heating and temperature controlling a heat medium liquid in each thawing pipe connected in a straight line in forcibly thawing frozen soil formed by a frozing method. SOLUTION: Thawing pipes 1 are buried in the frozen soil 14. A circulation inner pipe 2 for a heat medium liquid 20 is laid in each thawing pipe 1, and a U-shaped electric heater 3 is installed within the inner pipe 2 to be connected to an electric source 19 via a temperature controller 18. The heat medium liquid 20 circulates through each thawing pipe 1 connected in a straight line by a circulation pump 6 via a circulation pipe 11. At the outlet of the heat medium liquid 20 of each thawing pipe 1, a temperature sensor 17 is set for controlling temperature every thawing pipe 1. Thus, the circulation pump 6 needs not to be installed every outside large-sized hot water tank or individual thawing pipe 1 so that the device can be miniaturized, and the frozen soil is directly heated by an electric heater so that high temperature thawing can be done with a result that the thawing days can be shortened.

摘要： PURPOSE:To assemble segments at the designed positions. CONSTITUTION:A distance sensor 111 is fitted to an erector 109. The distance (r) to an existing segment 107 is measured by the distance sensor 111 while rotating the erector 109. In this time, the rotary angle theta of erector is measured also. The position of bolt holes 121 is calculated by use of the distance (r) and the rotary angle theta and the deviation from the designed position of the bolt hole is calculated. A new segment 113 is bolted with the existing segment 107 so as to cancel the deviation.

摘要： PURPOSE:To make it possible to obtain accurate position measuring data even if a shield machine body sideslips by mounting gyrocompasses on a succeeding truck connected to the shield machine body moving on a rail. CONSTITUTION:Gyrocompasses 10 and 10 are mounted on a succeeding truck 3 connected to a shield machine body 1 through a coupling rod 2 moving on a rail. After that, an angle made with the coupling rod 2 and shield machine bod 1 is detected by an angle detector 11 provided to a pivot with the coupling rod 2 and shield machine body 1. An angle made with the coupling rod 2 and the succeeding truck 3 is detected by an angle detector 12 provided to a pivot with the couplind rod 2 and succeeding truck 3. A position of the shield machine body 1 is calculated on the basis of an azimuthal angle of the gyrocompasses 10, position data and detection data of both angle detectors 11 and 12. At that time, the succeeding truck 3 moves on the rail, so that the gyrocompasses 10 are not influenced by sideslip of the shield machine body 1, and accurate position measuriang data can be obtained.

摘要： PURPOSE:To shorten a term of construction work and reduce construction cost. CONSTITUTION:When a first arrival shield machine (A) reaches a joint point, a side over cutter is brought over and then a cutter disk 6 and an inner ring are brought back. When a later arrival shield machine A1 arrives at the joint point, a side over cutter 7a is brought over. Then, a cutter disk 10 is fitted into the first arrival shield machine A. The later arrival shield machine A1 is pushed forward until a skin plate 2a comes in contact with a skin plate 2 of the first arrival shield machine A. Both tube shields 4 and 4a protected with the inner ring installed in the inner periphery at the tip of the skin plates are expanded so that a space between the skin plates 2 and 2a and a cutter disk tire 11 of the later arrival shield machine A1 may be sealed.

摘要： PURPOSE:To prevent the deformation, bucking, and the like of reinforcements from generated due to applied pressure after concrete is placed on a reinforcement cage, by binding the two reinforcement cage divided-bodies of U-type cross-sectional-areas formed with fusion- welded distributing bars and main bars folded in the shapes of U, to be confronted with each other, and by composing a reinforcement cage. CONSTITUTION:On the external sides of four main bars 2 arranged in parallel with each other, distributing bars 3 folded in the shapes of U are fusion-fitted, and divided bodies 4a, 4b are composed. After that, the one-side divided-body 4a is provided with the four distributing bars 3, and the width is set to be about 2/3 of the width of a reinforcement cage to be composed. After that, the other divided-body 4b is provided with eight distributing bars 3 in total, and the width of the four distributing bars 3 on the central section and at both the end sections is set to be about 2/3 of the width of the reinforcement cage, and the width of the other four distributing bars 3 is made roughly equal to the width of the reinforcement cage. When the two divided bodies of the U-shaped cross-sectional areas are bound to each other and great pressure is worked at the time of applying pressure to concrete, then with the force, bound sections 5 are deformed, and a section between the divided bodies 4a, 4b slids, and the force is absorbed, and deformation or buckling is prevented from being generated on the divided bodies 4a, 4b and the reinforcements.

摘要： PURPOSE:To measure the mutual relative positions of the cutter disc of the other shielding machine and a plurality of receiving sensors in a noncontact manner by detecting a signal transmitted from the front end of a boring pipe extended from one shielding machine or a shaft by the receiving sensors mounted to the cutter disc. CONSTITUTION:The position of the front end of a boring pipe 20 penetrated toward the other shielding machine B from one shielding machine A is measured by a boring-pit position detector set up to the shielding machine A. A transmission sensor 23 is fitted at the front end section of the boring pipe 20, and an angle detector 24 is installed to the shaft 2a of the rotary joint 2 of the shielding machine B while a plurality of receiving sensors 25 are mounted to the front of a cutter disc 3. Both detector and sensors 25 are connected to a controller 26 with a display 27 set up on the outside. The relative displacement of the transmission sensor 23 and the front of the cutter disc 3 is detected by utilizing these detector and sensors 25 in conformity with the propulsion of the shielding machine B.
