| <P>PROBLEM TO BE SOLVED: To provide a thrust transmitting material which is interposed between jacking pipes in executing a jacking method, and has a superior cushioning capability to effectively avoid damage to the jacking pipe even when a large, sharply concentrated, or complicated stress acts on the jacking pipe. <P>SOLUTION: The thrust transmitting material is obtained by foaming polystylene-resin expandable particles in a mold, and has a density of 0.17 to 0.67 g/cm<SP>3</SP>and an average cell diameter of 60 μm or less. This thrust transmitting material has a wide elasto-plasticity range on a stress-distortion curve, thus showing superior load absorptivity. Accordingly, even when subjected to the large, sharply concentrated, or complicated stress, the thrust transmitting material exerts a cushioning function to absorb the stress load, so as to prevent the damage to the jacking pipes. <P>COPYRIGHT: (C)2011,JPO&INPIT | ||||||

| PURPOSE: To improve working efficiency by a method wherein a cylindrical pipe is deformed into a flattened shape, which pipe is passed through a pipe embedded underground to the end thereof and the deformed cylindrical pipe is restored to a circular form so as to be connected to the forward end of the embedded pipe. CONSTITUTION: Hydraulic jacks 2a, 2b are set in a steel pipe 1 and forces are exerted onto the inner wall surface of the pipe 1 by means of the jacks 2a, 2b to flatten the pipe 1 within a limit of elastic deformation. And the flattened pipe 1 is put on a truck 3 having a low height, which is carried into an embedded pipe 5 having been laid underground from the rear end 5b thereof and passed through the pipe 5 to the forward end 5a thereof, following which the direction of the pipe 1 is changed so that it communicates with the pipe 5, while the jacks 2a, 2b are loosened, and the pipe 1 is connected to the forward end 5a of the pipe 5 by means of mechanical joint or the like. Thus no segments are required to constitute a short pipe so that working efficiency can be improved. | ||||||

CONSTITUTION:A tunnel excavating device body 1 is equipped with a skin plate 2, a plurality of propulsion jacks 3 and 3, and a discharge device 4. Then, outside ring heads 5 and 5, inside ring head 8 and preceding seal frames 11, 12, and 12 are projectingly installed onto the front side of the device body 1. An already laid pipe is continuously cut by the thrust forces of the propulsion jacks 3 and 3 and the cutting in two-stage on the inside and outsides of the already laid pipe by the inside and outside ring heads 5, 5, and 8, and the crashed pipe is removed. Further, the bank of the peripheral wall after the removal of the already laid pipe is sealed by the outside ring heads 5 and 5 and the skin plate 2, and protected, and the parallel laying of a new pipe is permitted. Further, the inside of the already laid pipe is previously sealed by the preceding sealing frames 11, 12, and 12, and work can be carried out smoothly and easily. | ||||||

| PURPOSE:To widen an application range by taking in a ready-set pipe body piece crushed and machined with an extra-hard reamer, from a slit, to convey the piece on the rear side with a conveyor, and by interlocking a newly set pipe set on the rear side, with the reamer, to insert the newly set pipe. CONSTITUTION:An extra-hard reamer 1 is formed in the shape of a file by fusion-welding an extra-hard steel on a conic surface rugged-section. After that, from a vertical pit 12 on one side, to the end section of a reay-set pipe 10, the reamer 1 of the same diameter is butted, and the reamer 1 is rotated. After that, the concrete wall surface of the pipe 10 is crushed, and a steel member set in concrete is machined with a file-formed extra-hard steel. The crushed and machined pieces or the like are taken in from a slit 2 set on a machined section, and are conveyed to the side of the vertical pit 12, and a newly set pipe 11 provided with a penetration ring 6 is interlocked with the reamer 1 and is inserted by a propelling device 7. Accordingly, the application range of the pipe can be widened. | ||||||

| PURPOSE:To easily replace pipes regardless of the kinds of existing pipes by a method in which a cylindrical pipe is inserted into an existing pipe buried under the ground while cutting off it axially from inside, a temporary pipe is inserted to push out the cylindrical pipe, and the temporary pipe is replaced by a new pipe. CONSTITUTION:By using a device in which disc cutters 3 are attached to the periphery of a cylindrical pipe 6 to be advanced by a propulsory device, an existing underground pipe 1 is axially cut off from inside. The cut pipe 1 is released from earth pressures and the pipe 6 is inserted into the pipe 1 to prevent the degradation of the pipe 1. A temporary pipe 15 of a diameter similar to the outside diameter of the pipe 6 is further inserted to push out the pipe 6 and the cut pipe 1 to the other end. The pipe 15 is then replaced by a new pipe 16. | ||||||

| PURPOSE:To safely and exactly transmit propulsive forces while protecting inner layer by a method in which an auxiliary plate is attached to the inner surface of the end of an outer layer of a pipe in which an anticorrosive inner layer is connected with a high-strength outer pipe by an intermediate pipe for propulsive excavation work. CONSTITUTION:Anticorrosive inner layers 2 are connected with high-strength outer layers 3 by intermediate layers 4 to make up pipes 1A and 1B capable of transmitting propulsive forces by the layers 3 for propulsive excavation work. Auxiliary plates 5, 8 and 9 are attached to the inner surface of the ends of the layers 1 for reinforcing the ends of the layers 3. A mid-push jack 12 is detachably set between the adjacent pipes 1A and 1B and the pipe 1A in front is advanced for stepwise proceeding of pipe laying work. | ||||||

CONSTITUTION:From a starting vertical shaft, propeller pipe bodies 18d, 18e with cutting edges fitted at the only tip sections are connected to each other in order and are pressure-applying-propelled, and a conduit line is formed under ground. Then, on the way of the conduit line, at specified intervals, ring-formed concreted layers are formed on the outer periphery. In this case, a joint 32 fitted on a section between the respective propeller pipe bodies 18d, 18e is composed of a ring-formed section 36 bridged between step sections 34, 34 on the outer peripheral surfaces of the adjacent propeller pipe bodies 18d, 18e, and a pair of flange sections 38, 38 arranged on the inner peripheral surfaces. Besides, along the peripheral direction of the ring-formed section 36, a plurality of sockets 42 having check valves 44 are arranged, and via the sockets, concreting agent is injected into outer peripheral ground. | ||||||
