摘要： PROBLEM TO BE SOLVED: To form recess protrusion parts a joint easily at low cost and positively connect both concrete structures to be connected. SOLUTION: Joint structure 1 consists of both concrete structures 2 of the same structure with insert holes 3 formed at the connected faces 2a, and a joint fitting 4 with both end parts having insert parts 4a that can be inserted in the insert holes 3 of both connect structures 2. One insert part 4a of the joint fitting 4 is inserted in the insert hole 3 to fit the joint fitting 4 to one concrete structure 2, and the other insert part 4a of the joint fitting 4 is inserted in the insert hole 3 of the other concrete structure 2 to connect both concrete structures 2 through one (one kind of) joint fitting 4. At the time of inserting the insert part 4a into the insert hole 3, the joint fitting 4 is pressed to the insert hole 3 and locked to a locking part 3a by the action of a slit 4c and a pawl part 4d provided at the joint fitting 4. An inserted state can thereby be maintained positively.

摘要： PURPOSE: To connect segments easily and in a short time without using a bolt by installing a male metal fitting on one side and a female metal fitting on the other side in a recessed part of a joint surface in parallel to a tunnel axis for tunnel lining cement and fitting with a wedge. CONSTITUTION: A recessed part 3 is installed to a joint surface in parallel to a tunnel axis of a tunnel lining segment while a female metal fitting 1 having a slanted fitting part, whose head is gradually slanted toward a cutting face, is installed to a recessed part 3 of one joint surface. A male metal fitting 2, which wedges in the female metal fitting 1, is installed to the recessed part 3 on the other side. A total space of the recessed part of the joint required to fit both male and female metal fittings 1 and 2 is found from an equation where D>=(Bm -tm )sinθ+tf +tm , wherein Bm and tm stands for the outside length and thickness of the fitting part of the male metal fitting 2 while tf for the thickness of the female metal fitting 1, and θ stands for a slanted angle of the fitting part. The slanted surface of the male metal fitting 2 of a segment A' is fitted in and wedged with a slanted fitting part of the female metal fitting 2 of a segment A so that they may be connected. A succeeding segment joint is fitted in a preassembled ring segment and aligned and fixed with a through bolt.

摘要： PURPOSE: To excavate the unexcavatable portions between cutter headers by fitting multiple cutter headers to the front end section of a main body so that they are kept perpendicular to the advancing direction and the rotary shafts are kept in parallel with the advancing direction, and fitting a drum cutter head so that its rotary shaft is kept perpendicular to the advancing direction and in parallel with the rotary shafts of the cutter heads. CONSTITUTION: A pair of the first drive motors are driven to rotate a pair of cutter heads 2, the second drive motor is driven to rotate a drum cutter head 3, and a main body 1 is advanced. The first tunnel having a double enveloping cross section is precedingly excavated by the drum cutter head 3. Both side sections of the first tunnel is excavated by a pair of cutter heads 2 to form a pair of the second tunnels each having a circular cross section. The first tunnel and a pair of the second tunnels are connected to form a tunnel having an elliptic cross section as a whole. When the drum cutter head 3 is rotatively driven, the excavating force is increased. The excavation work efficiency of the whole excavator can be improved.

摘要： PURPOSE:To surely prevent deformation including the greater radius of curvature of upper and lower tunnel walls by bolting a web at the end of reinforcement and a connecting plate installed at a segment together via splicing plates. CONSTITUTION:Circular segments NS1-NS4 are jointed together in sequence to form a tunnel structure 1 so that reinforcements 8, 8 under tension are connected to the given segments NS1-NS4 horizontally to the upper or lower part inside the structure 1. In such a connection, the reinforcing material 8 is made up with a long shape steel such as a H-steel and a channel steel. The segments NS1-NS4 connected to both ends of the reinforcement 8 are provided with connecting plates 10... protruded inside the structure 1 in horizontal and having vertical connecting planes. Webs 8a, 8a at the end of the reinforcement 8 and the connecting plate 10 are bolted together via splicing plates 12....

摘要： PURPOSE:To provide the capability of coping with internal pressure by forming a shear resistance section such as ribs staggered along the peripheral direction of lining, on the ring joint surface between segments, and filling the gap of the jointed surface with a filler for jointing the segments to each other. CONSTITUTION:In space inside the skin plate 20 of a shield machine, synthetic segments 1A are held with an erector and supported on a mobile timbering device 21. Concrete 22 is placed in the concrete filling space 6 of a steel hull from a concrete filling port. Then, the coupling sections 12 and 13 of the segments 1A joined together via a seal member 25, and filling space 26 formed out of the filling recesses of both segments 1A is filled with a filler 27. While a shield machine is being propelled with a propulsion jack 23, a back-filling material 24 is fed through a back-filling port 16. According to this construction, segment rings, particularly when subjected to internal pressure, can effectively cooperate with each other for resisting axial tension and cross sectional shear.
