摘要： PROBLEM TO BE SOLVED: To control a direction and posture at a low cost without needing a machine space in a simple structure by forming a taper hood on the edge of a shield frame, and changing the excavation cross section shape of the variable cutter of an excavation cross section shape provided on the front face of the frame to control an excavation direction and posture. SOLUTION: A shield frame 10 being a shield body is formed in the form of a cylinder with a bottom making a rectangular front part 1 the bottom, and divided into the front drum 20 of a bottom side and the rear drum of an opening side. Excavation cross section shape variable cutters 4, 5 are matched to the size of the front part 1 on the front part 1 of the front drum to be rotatably provided in one row. In addition, a taper hood 11 obliquely inclining both the right and left parts of the front part 1 to produce rotation moment by mounting on the excavation residue part formed by the excavation cross section shape variable cutters 4, 5 on the front part 1 of the shield frame 10. The excavation cross section shape of the excavation cross section shape variable cutters 4, 5 is changed to control the boring direction and posture.

摘要： PROBLEM TO BE SOLVED: To provide a shield machine capable of carrying out work for sharp curves and continuous borings. SOLUTION: A shield machine includes a machine main body 10, a cutter 12, a chamber 14, an earth and sand conveying pump 18 and an earth and sand conveying pipe 20. The rear end side of the chamber 14 is separately formed by a partition wall, an earth and sand excavated by the cutter 12 set to the front side is taken into the inside of the chamber to fill and it is opposed to earth pressure on the side of a cutting face to stabilize the cutting face. The pump 18 is a pressure adjusting uniaxial eccentric screw pump, and it is so provided that it is directly connected to the inside of the chamber 14. The earth and sand conveying pipe 20 is constituted of a cylindrical body of synthetic resin or the like having flexibility, one end side thereof is connected to a discharge port of the pump 18, at the same time, the rear end side is extented backward of a following truck 28, and the rear end is opened at a position thereof.

摘要： PROBLEM TO BE SOLVED: To enhance efficiency of excavation corresponding to the ground condition in a wide range by setting the basic frequency of an electric motor high in the case of excavation of a hard rock layer and setting it low in the case of the excavation of a weak layer, while inverter-controlling the motor. SOLUTION: For instance, a cutter head provided on a front side is rotated and driven by four high torque four-pole electric motors 4 attached to the supporter 2 of a cutter head drive part 1. High torque is obtained in a low rotation area by switching a basic frequency and lowering of the efficiency of output torque is prevented even in a high rotation area. As the result, the ground of the wide range of a weak layer to a hard rock layer is efficiently excavated by a rotating speed and torque corresponding to each ground quality condition. In addition, a low frequency lower than a commercial frequency is made the basic frequency, so that even when the electric motor of the small number of the poles is driven, the equivalent high torque as the electric motor of the large number of the poles can be obtained. Thereby ground correspondence of a tunnel excavator used for the excavation of a hard rock part can be improved.
