摘要： 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.

摘要： 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.

摘要： A rotary actuator includes a cup-shaped piston which is movable back and forth and rotatable on its axis. A driving shaft has on its circumferential face a threaded area engaging with a threaded internal face of the cup-shaped piston. The driving shaft can be rotated on its axis during rectilinear motion of the cup-shaped piston. A rotary member has an area engaging with an outer portion of the cup-shaped piston. A casing accommodates the cup-shaped piston, the driving shaft, and the rotary member. The casing has a slit which can be tightened for securing the rotary member to the casing. A regulating member limits the length of strokes of the cup-shaped piston.

摘要： 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.

摘要： A shield-type tunneling machine comprises a shield body having a front portion converging gradually rearward, a crankshaft journalled rotatably by a diaphragm provided in the shield body, a drive mechanism connected to an end of the crankshaft and a conical or frustoconical rotary head supported rotatably by the other end and disposed in the front portion of the shield body to be turned eccentrically, a gear mechanism for forcibly rotate the rotary head and a means for discharging debris from a front area of the diaphragm to a rear area. The tunneling machine, when thrusted in the ground by a jack, receives earth and sand into the front portion of the shield body and compresses them between the rotary head and the shield body to send them to the rear. The machine can be used for a pipe jacking as well as the tunneling in the soft ground.

摘要： 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.
