摘要： PROBLEM TO BE SOLVED: To keep a working face stable during the stop of propulsion of a shield without using pressurized slurry and without closing a slit opening/closing device mounted to a cutter. SOLUTION: In this slurry shield method, a shield 10 is driven forward while feeding slurry to a front chamber 14 of a partition wall 12 in the shield 10. In the case of excavating a working face 20, at the time of stopping propulsion of the shield 10, a thickener is fed into the slurry in the chamber 14 and agitated to heighten the viscosity of the slurry in the chamber 14, thus keeping the working face 20 stable.

摘要： PROBLEM TO BE SOLVED: To attain accurate control by calculating the weight of removed earth within a specified range of each ring from a flow rate and density, comparing the weight of removed earth with measured weight and selecting a control type in response to a result. SOLUTION: When a new ring rn is constructed, excavation is conducted up to the spot Pn " of one tenth of a stroke from a starting spot Pn , the measured values of a flowmeter 24 and a densitometer 25 are input to a computer 28 and the total weight of removed earth W1 is computed. The computer 28 reads the total weight of removed earth measured W0 of a load cell 26, and compares weight W0 and W1 . When the error is kept within 5%, the error is regarded at a value within tolerance, and the control of the quantity of soil based on the measured values of the flowmeter 24 and the densitometer 25 is selected. When the error exceeds 5%, the control of the quantity of soil by the removed measured value of the flowmeter 24 and the computed value of the density of earth obtained from the measured value of the load cell 26 is selected. Excavation is conducted from a spot Pn ' to the arrival target spot Pn " by the control of the quantity of soil selected. Accordingly, the quantity of soil can be controlled accurately at a real time.

摘要： PROBLEM TO BE SOLVED: To excavate tunnels having small diameters at places made to eccentric to the axial centers of tunnels having large diameters while maximally reducing the stepped sections of the outside diameters of the tunnels when the shield tunnels having different diameters are executed continuously. SOLUTION: In the master-slave shield machine 10, the slave shield machine 21 is arranged at a place made to eccentric to a lower section to the master shield machine 11. Since eccentric multispindle type master cutters 14 are installed to the master shield machine 11, the master cutters 14 excavate a ground while being rocked centering around an axial center O1 as their postures are kept as they are held without being inclined left and right. Accordingly, the master cutter 14 excavates a space section between the master cutter 14 and a slave cutter 24 without leaving, and a shield tunnel having a large diameter corresponding to the master-slave shield machine 10 can be excavated. When the slave shield machine 21 is detached from the master shield machine 11 and excavation is conducted only by the slave shield machine 21, a tunnel having a small diameter can be excavated by the slave cutter 24.

摘要： PROBLEM TO BE SOLVED: To improve workability of reinforcing bar arrangement on a secondary lining of a shield tunnel and to secure safety. SOLUTION: A primarily lined segment 11 is connected to a shield tunnel by a segment bolt 14, a base end part of a reinforcing bar support fitting 20 formed in a U shape in plan view is installed on a screw part 14a of this segment bolt 14, and a cutout part provided on a head end of the reinforcing bar support fitting 20 is projected on a surface of the segment 11. A distributing bar 30 is arranged roughly at constant height from the surface of the segment 11 in the axial direction of the shield tunnel by engaging the distributing bar 30 with this cutout part and sequentially extending a new distributing bar to an end part of the distributing bar 30 by brinding it with a binding wire 31. Additionally, when a main reinforcing bar 32 is arranged in the circumferential direction of the shield tunnel orthogonal to the distributing bar 30, reinforcing bar arrangement on a secondary lining is finished on the surface of the segment 11.
