摘要： PURPOSE:To speed execution by combining position and direction of a shield excavator virtually at operations to make a correcting planned line based on the kind and number of segment rings on hand when position and direction of the shield excavator are in excess of allowable value and are slipped from the planned line. CONSTITUTION:When position and direction of a shield excavator 1 are in excess of allowable value due to radical change of the ground or control fault, etc., and are slipped from a planned line K, position and direction thereof are combined at operations until the following formular is satisfied based on the kind and number of segment rings on hand to make a correcting planned line H. The segment rings have such kinds as a standard ring formed of a normal cylindrical body and as a taper ring cut off the end of the cylindrical body slantly. ¦Declination¦

摘要： PURPOSE:To make it possible to excavate a tunnel with high efficiency without causing any fall in a bedrock relatively lacking in self-independence. CONSTITUTION:A deck 7 penetrated into a bedrock 61 in the approximately horizontal position, pipes 16 developing mortar piles by providing mortar for a cave when the pipes are inserted into the ceiling section of the bedrock and are pulled out thereof, a device 31 placing concrete to the lower half of the side of a tunnel and a lining device 26 placing concrete to the upper half of the tunnel are provided to a traveling frame 1 in which excavators 41 and 43 are carried. The deck 7 is penetrated into the bedrock in the approximately horizontal position to stabilize the bedrock and, at the same time, the bedrock is divided into upper and lower parts to excavate the divided bedrocks respectively.

摘要： PURPOSE:To turn a shield excavator without applying excessive load and displacement to the ground by using a control system automatically judging the quality of the turning radius in consideration of the soil property. CONSTITUTION:When a shield excavator is turned for an excavation, the turning radius R and the turning center C are inputted to a control device 14 via an input device 16. When the turning radius R set by an operator is judged satisfactory by the control device, a shield jack 9 is driven and controlled by a shield sequencer 18 for an excavation along a circular arc specified by this turning radius R. When it is displayed on a display 17 that the set turning radius R is inadequate, the operator cancels the previous turning radius and sets a new turning radius. When it is judged satisfactory, the shield jack 9 is driven and controlled for an excavation along the circular arc specified by the new turning radius.

摘要： PURPOSE:To enable the excavation along a planned line in part of a circular arc by obtaining a placing direction of the next ring with respect to the existing ring as a control angle every each ring, and learning relation between the control angle and a dynamic point position of total thrust. CONSTITUTION:A controller 20 having an automatic directional control system and a shield sequencer 21 are provided in the inside of an excavator body 1, and a personal computer 22 having an operation control system is installed on the ground. After that, position and direction data detected by earth pressure detected by an earth pressure cell 23, position and direction data detected by an instrument incorporating a gyro and a level, rolling data detected by a gyro 25, stroke data of a shield jack 9 detected by a stroke gauge 26 and supply oil pressure data detected by a pressure gauge 27 are inputted to the controller 20. Then, a CPU transmits signals corresponding to a dynamic point position to the shield sequencer 21, and opening and shutting control of a valve 30 is made. The controller 20 obtains relation between the control angle and the dynamic point position as approximate value based on statistical data of the dynamic point position of total thrust against the control angle between rings, and the dynamic point position of the next ring is assumed to control a shield jack so as to act total thrust of the jack on the dynamic point position.

摘要： PURPOSE:To improve water stopping performance by changing the strokes of plural intrusion ring extruding jacks for extruding intrusion rings jack by jack so as to adjust the intrusion angle and length of the intrusion ring into an intrusion chamber, thus performing water stop control. CONSTITUTION:Intrusion rings 13 are enclosed between the outer cylinder 11 and inner cylinder 12 of a first shield machine 1, and there are also provided with intrusion ring extruding jacks 17, 17. An intrusion chambers 23 are formed between the outer cylinder 21 and inner cylinder 22 of a second shield machine 2, and pressure receiving rubber 34 is provided in each chamber 23. Drilling is performed from both ends of a tunnel by the shield machines 1, 2. The shield machine 1 is placed to face the preceding shield machine 2. A cutter device 10 is then enclosed, and the jacks 17 are driven to bring the rings 13 into contact with the rubber pieces 34. At this time, the stroke of each jack 17 is changed taking account of a deflection angle at the 1 time of jointing, thus adjusting the intrusion angle and length of the ring 13 into the chamber 23. Water stopping performance can be thereby improved.
