摘要： PURPOSE: To prevent the change of porosity by sticking an adhesive, provided with rubber-like elasticity after adhesion, to the surface of solid pieces such as crushed stones, and throwing these solid pieces into the hole of the ground so as to construct a solid piece porous body with numerous solid pieces adhering to one another. CONSTITUTION: The compressor 26 of an air hammer type boring machine 20 is driven to apply impact force to the ground by the tip of a ground mark 23 so as to compaction-excavate and to press a steel pipe into the ground down to the specified depth. The ground mark 23 is then pulled up and taken out of the steel pipe 30. An adhesive provided with rubber-like elasticity after adhesion is stuck to the surface of solid pieces such as crushed stones, and these solid pieces are thrown in, and the steel pipe 30 is pulled out so as to construct a porous body with numerous solid pieces adhering to one another in the ground.

摘要： PURPOSE:To construct a tunnel, in which a sectional diameter is changed, by excavating the large-diametral tunnel up to the predetermined position of diametral contraction by master and slave shielding machines, stopping excavation by the master shielding machine and starting the slave machine from the master machine while a fixed member is used as a reaction receiver. CONSTITUTION:A slave shielding machine 20 is housed in a master shielding machine 10 in a retractable manner, and an empty section 22, to and from which each cutter disk 11, 21 for each shielding machine 10, 20 is projected and retreated, is formed. The front ends of the rods of shielding jacks 23 for the slave shielding machine 20 are connected previously into the master shielding machine 10 in a press-touchable and detachable manner at that time, and both shielding machines 10, 20 are coupled. The slave shielding machine 20 is started from the inside of the master shielding machine 10 in the ground. Accordingly, the diameter of a tunnel during excavation is contracted smoothly from its midway, and excavation is continued, thus constructing the tunnel, in which the sectional diameter is changed.

摘要： PURPOSE:To enhance safety and reduce a construction period by bringing a branch shield machine into an inner segment ring and closing a second window hole from inside by turning and jacking up the shield machine in alignment with the first and second window holes. CONSTITUTION:An outer segment ring 10 and an inner segment ring 20 which is housed in such a fashion that it may turn about its axis, are build-up in double structure. In this case, a first window hole 11 and a second window hole 21 are installed to the inner segment 10 and the outer ring segment 20 respectively. The first window hole 11 is closed by turning the inner ring segment 10. A branch shield machine 30 is launched by opening the first window hole 11, thereby excavating a branch tunnel. When opening the first window hole 11, the inner segment ring 10 is turned with the second window hole 21 closed with a branch shield machine 30. This construction makes it possible to prevent the collapse of fallen around by allowing the machine 30 close to the fallen ground to receive the earth and earth pressure outside the first window hole 11 and keep the underground not exposed in the pit.

摘要： PURPOSE:To eliminate necessity of pile-driving for branching by connecting a main skin plate of a main line shield excavator to the folding type and proceeding with excavation at a predetermined point of branching by a branch line shield machine from a window hole of a secondary skin plate store in a middle drum. CONSTITUTION:A main line tunnel T(1) is excavated, by propelling force of a pray shield jack 51 which is stored in a rear drum 130, to a predetermined point of branching, by a main line shield excavator 1 in which a branch line shield excavator 2 is stored, with a front drum 110, a middle drum 120 and the rear drum 130 connected Then, the middle drum 120 and the rear drum 130 are disconnected at the predetermined point of branching, with a secondary skin plate 121 and the rear drum 130 left at the branching point, using the secondary skin plate 121 for receiving reaction force, excavation is continued with the front drum 110 and the middle drum 120, propelled by a secondary folding jack 52. And the front drum 110 and the middle drum 120 are driven l forwards and if the rear end of the middle drum 120 passes by the position of a window hole 123 of the secondary skin plate 121, a branch line tunnel T (2) is excavated from the window hole 123 by the branch line shield machine 2.

摘要： PROBLEM TO BE SOLVED: To provide a segment joint structure capable of easily connecting mutual segments, and capable of reducing a burden to the segments when tensile force acts between the segments after the connection. SOLUTION: A male joint member 2 and a female joint member 8 are embedded in mutual end parts of the connecting segments 1A and 1B. These male- female joint members 2 and 8 are formed so as to obtain a strong connecting state only by inserting the male joint member 2 into the female joint member 8 by using a lock ring 11 and a backup ring 12. A connecting shaft body 4 being a projecting member of the male joint member 2 is housed in a male joint body 3 so as to be movable in the shaft direction even after connecting the male-female joint members 2 and 8. A spring washer 6 is arranged for resisting the tensile force by being deformed when the tensile force acts between the male-female joint members 2 and 8.

摘要： PROBLEM TO BE SOLVED: To provide a sealed panel which facilitates lining of a sealed material, reduces leakage from a gap at a joint portion, can be produced at a low cost, and is free from breakage thereof due to hydraulic pressure of underground water, etc., and to provide a sealing structure using the sealed panel. SOLUTION: The sealed panel is laid on an internal wall of a structure in order to seal the same, and formed of an almost rectangular flat panel 1, a stepped panel 7, and sealing members 6, 14. The flat panel 1 includes support portions 2 protruding toward the structure. The stepped panel 7 consists of an external brim portion 12 adjoining to the structure, a flat portion 10, and a step portion 11 extending to both the external brim portion 12 and the flat portion 10, for housing a surface of the flat panel 1, facing to an inner side of the structure in a manner being almost flush with a surface of the flat portion 10, facing to the inner side of the structure. The sealing members 6, 14 are arranged on superposing portions 5, 13 of the flat panel 1 and the stepped panel 7, respectively. The sealing structure employs the sealing panel thus constructed.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method for controlling direction of a shield machine capable of preventing the nose down of the shield machine in the soft ground and capable of finely adjusting in the direction control. SOLUTION: This device 10 for controlling direction of a shield machine is provided with a filling means 40 for filling the chemicals to the soil in the periphery of a shield machine 100 and a filling nozzle 43 for filling the chemicals. The reaction force works to the shield machine in an opposite direction to the chemicals filling direction by pressurizing and filling the chemicals from the filling nozzle 43 during the excavating work of the shield machine. Attitude of the shield machine and direction of the excavation can be controlled by utilizing this reaction force.
