Abstract: A shield tunneling machine comprises a shield body having a soil chamber, an inside chamber and a partition wall. The soil chamber has a conical peripheral surface converging gradually rearward. A crankshaft having an eccentric portion is rotatably supported by the partition wall at the center of the partition wall corresponding to the axis of the shield body. A cutter disc with roller bits is secured to a front end of the crankshaft, and a conical rotor is rotatably mounted on the eccentric portion of the crankshaft behind the cutter disc. Since the cutter disc is rotated at an increased rotary velocity by five to ten times as many as that of a cutter disc in a conventional shield tunneling machine, crushing of gravel can be efficiently carried out by the cutter disc with roller bits in cooperation with the conical rotor mounted on the crankshaft.

Abstract: First and second frame assemblies (18, 20) are respectively provided with a pair of plate-like earth retainers (24, 36) and are alternately advanced by propulsion jacks (22). While the first and second frame assemblies are alternately advanced, the ground (14) is excavated to form a channel (16). A reaction force acting on the first frame assembly (18) when the second frame assembly (20) is advanced and a reaction force acting on the second frame assembly (20) when the first frame assembly (18) is advanced are respectively transmitted to the ground defining the channel by the action of first and second position maintaining force transmitting members and jacks (32, 52). When the first and second frame assemblies (18, 20) are advanced by required distances, a new pipe (12) is placed in the channel and connected to a pipe (12) already installed.

Abstract: A direction correcting device for a shield tunnelling machine having a shield body provided with a head portion and a tail portion following the head portion corrects the direction of the head portion relative to the tail portion. The device includes three jacks, each jack having two connecting portions relatively displaced in the axial direction of the tail portion, and a connecting body for interconnecting the head portion and the tail portion to permit the head portion and the tail portion to swing and to prevent the head portion and the tail portion from relatively displacing in the axial direction of the tail portion. Each of the jacks is connected at one connecting portion to the head portion and connected at the other connecting portion to the tail portion. The jacks and the connecting body are disposed around the axis of the tail portion at angular intervals.

Abstract: A method for excavating a tunnel wherein the muck from the tunnel face is admitted into the shield; the muck is pressed by a pressure of a predetermined level higher than an active earth pressure in the face and lower than a passive earth pressure as the shield body is moved forward, thereby establishing the balance between the earth pressure in the face ground and the muck pressure; and a liquid of a level balancing the underground water pressure is used to resist the underground water, thereby preventing movement of the underground water, whereby the face is maintained stable; and when the muck pressure is raised over the predetermined level, the muck is discharged out of the shield. A shield tunneling machine embodying the above described method comprises a cutter head (24,124) allowing the passing of the muck therethrough, a diaphragm (14,114) provided in the shield body (10,110), a muck inlet (16,116) provided in the diaphragm, a cover member (50,148,149) adapted to open and close the muck inlet and coupled to an operating means (52,160) presetting the muck pressure at the aforesaid predetermined level, and a muck chamber provided behind the diaphragm and usually charged with a liquid.

Abstract: A drawing device 4 is mounted in a drawing shaft 3, and pipe replacement device A connected with new pipes is arranged on the side of starting shaft 2, wherein the drawing device 4 and the pipe replacement device A is connected through pull-rods 5 inserted into existing pipes with each other. The pipe replacement device A is comprised of a cutting part 11 including cutter bodies 14 (shanks 14a to 14i) arranged in the axial direction and at angular intervals in the circumferential direction, an expanding part 12 having expanding rollers 18a to 18f, and a connecting part 13. Each cutter body 14 has a plurality of cutting edges, wherein distances between the respective cutting edges and the center of the circle become larger in order from the forward side toward the backward side. While the pipe replacement device A is traveled in the inside of cast iron pipes, the inner wall of cast iron pipes is cut by the cutter bodies 14 to form grooves. Splitting of existing pipes into arc-shaped pieces 1a is made starting from the grooves. Arc-shaped pieces 1a are pressed into the ground, by which a tunnel 7 surrounded by arc-shaped pieces 1a and portions of consolidated earth is formed, while new pipes 6 are introduced into the tunnel 7, and besides the new pipes 6 are protected by protective armors formed of arc-shaped pieces 1a.

Abstract: A pipe propelling device comprises two sets of jack assemblies spaced from each other and arranged in the direction of propelling the pipe in a vertical shaft having a reacting shaft wall so that small diameter pipes such as water supply and drainage pipes, gas pipes and cable lying pipes can be propelled from the interior to the exterior of the vertical shaft by the extension of two sets of the jack assemblies. To reduce the dimension of the vertical shaft to propel the pipe, eliminate the interposition of a strut in propelling the pipe and secure an operative space in the vertical shaft, the jack assemblies comprise a plurality of first stage jacks connected to the reacting shaft wall and at least one second stage jack, a cylinder of the second stage jack being connected to cylinders of the first stage jacks.
