摘要： PROBLEM TO BE SOLVED: To bore window provided with an effective bore diameter equal to an allowable bore diameter by applying revolving motion to a pair of vertical cutters while reciprocating them, which are rotated by means of motor drive, upward and downward followingly along a curved face of an outer circumference of a main pipe. SOLUTION: When a feed drum 10 is rotated, a motor block 4 built in the inside of the feed drum 10 is rotated together. In this rotation, cam rollers 24, 24a on a body upper 23 side are engaged in a cam groove 13 in the feed drum 10 and the body upper 23 is fixed, so that vertical motion following the cam groove 13 is applied to the feed drum 10. This vertical motion matches with the curved face of an outer circumference of a main pipe. At the same time, a cutting key 8 on the motor block 4 side is engaged in a cutting key groove on the feed drum 10 side, so that the motor block 4 is rotated integrally with the feed drum 10. As a result, cutters 3, 3a bore the main pipe circularly while performing rotation and revolution, and a window with an effective bore diameter equal to an allowable bore diameter is formed.

摘要： PURPOSE:To provide a scraper for a large-diameter resin tube not removed even when the end face of the tube is not perpendicular or the tip side of the tube is tapered in the outer diameter direction by forming the outer diameter of a capstan roller located at the tip side of the resin tube larger than the outer diameter of a capstan roller located inside it. CONSTITUTION:The opening tip of a resin tube A is clamped by capstan rollers 3, 3a and a roller 10, the capstan rollers 3, 3a are driven by a motor, and the surface B is peeled by a blade while a main body 1 is revolved. A drive screw 18 is rotated by a handle 29, and a blade holder 22 is moved along a capstan 2 by the action of a feed screw 19. The surface is spirally peeled by the actions of the movement and revolution, the outer diameter of the roller 3 on the end face side of the tube A is set larger than the outer diameter of the inside roller 3a, a scraper is revolved along the outer periphery of the resin tube A by the drive of the motor, and directivity is invariably applied to the scraper into contact with the end face of the tube.

摘要： PURPOSE:To provide a scraper to simply and quickly peel off the surface of a large bore diameter resin pipe. CONSTITUTION:The thick wall of the bevel of a resin pipe A is held between a capstan roller 3 and a roller 10, and the surface B is peeled off with a blade as the capstan roller 3 is driven by a motor to revolve a main body 1, and moreover a driving screw 18 is rotated by a handle to bring a feed screw 19 into action for moving a blade holder along a capstan 2, and the surface is therefore spirally peeled off by the above moving and revolving actions. Since the scraper is revolved along the outer periphery of the resin pipe A by motor- driving, a peeling work is easy and effective in the case of a large bore diameter pipe, and its surface is finely and spirally peeled off.

摘要： PROBLEM TO BE SOLVED: To provide a simple and accurate stress evaluation method of a piping structure for a so-called station piping which branches from a main pipe laid underground and has a plurality of inflection points on the ground.
SOLUTION: Assuming that a vertical directional displacement δ at an end of a branch pipe 9c is sum of a displacement δ1 caused by in-vertical-plane moment acting on the branch pipe 9c, a displacement δ2 caused by torsional deformation of a branch pipe 9b, and a displacement δ3 caused by bending moment of a branch pipe 9a toward the branch pipe 9b, a stress evaluation method of a piping structure evaluates a maximum stress σ arising in a piping structure using a following expression (10): the expression (10) is as follows: σ={3EGd
o (2a+2b+c)δ}/{cG(12a
2 +12ab+4bc+10ca+c
2 )+3bc
2 E}, where a, b, c are length of the branch pipes 9a, 9b, 9c respectively, E is a vertical elastic coefficient, G is a horizontal elastic coefficient, d
o is an outer diameter of the branch pipe, δ is a vertical directional displacement relative to the main pipe at a support part.

摘要： PROBLEM TO BE SOLVED: To provide a stress evaluating method and a stress evaluating device for evaluating a curved pipe for simply and precisely calculating the stress generated in the curved pipe constituting a pipe line.
SOLUTION: Regarding the curved pipe A to be evaluated, if a measuring limit is exceeded, the stress evaluation is performed as follows: a distribution of the stress in a curved pipe B being adjacent to the pipe A is measured by a magnetic anisotropy sensor, flatness value of the curved pipe B is obtained from the relational formula of the stress-moment relation and the moment-flatness value, and an initial diameter of the pipe B is obtained from a measure of the diameter of the pipe B. The flatness vale of the pipe A is obtained from the measurement of the diameter of the pipe A considering that the initial value of diameter of the pipe B is equivalent to that of the pipe A, and the distribution of the stress in the curved pipe A is calculated using the relational formula of moment-flatness value and the relational formula of stress-moment. Wherein, the relational formula of moment-flatness value is derived e.g. by developing the theoretical formula of Rodabaugh & George etc., regarding displacement in a sectional direction of the curved pipe.

摘要： PURPOSE:To enable a reclaiming pipe to branch having sufficient strength by induction-welding a seat part of a branch joint to the reclaiming pipe, and also clamping an external surface of a cast iron pipe with a clamp member. CONSTITUTION:A synthetic resin-made reclaiming pipe 14 is inserted in a folding condition into a cast iron pipe 12, after insertion, expanded by such as blowing hot air and closely attached to an internal wall in the cast iron pipe 12. A synthetic resin-made branch joint 16 is formed by providing an almost disk- shaped seat part 22 and by burying in its internal surface a magnetic alloy heater 28. This branch joint 16 is positioned in an external surface of the reclaiming pipe 14 and pressed thereto by using a pressing device 30, and the reclaiming pipe 14 is deformed so as to be along the seat part 22, so as to closely attach the seat part 22 to the reclaiming pipe 14. In this condition, a high frequency current is given to the magnetic alloy heater 28, to heat a connecting surface, between the seat part 22 and the reclaiming pipe 14, welded, and then an external surface of the cast iron pipe is clamped by a clamp member 20 so as to reinforce a connecting part.
