摘要： PURPOSE: To inhibit outflow of concrete from the end side by providing an end plate slidably in the circumferential direction adjacent to an annular pressure retaining ring holding compression of concrete. CONSTITUTION: An inner form 5 is positioned in the rear of a shield machine 4, and the advance of the shield machine 4 is performed by taking reaction force in the inner form 5. On the other hand, outflow of concrete from the end side is inhibited by a press ring formed by an annular box 3 and an annular end plate 8. The annular end plate 8 has an inner diameter substantially equal to the outer diameter of the inner frame 5. The placed concrete is pressurized by a press jack 6 through the press ring, and after the removal of the press ring, pressurization is continued by a pressure retaining ring 1.

摘要： PURPOSE:To aim at shortening the constructing period by drilling ahead a shield machine, with the front cover ring located in the receding state and the tip formed cover ring matching the side surface of an existing tunnel expecting docking in the protruding state so as to shield the entire peripheral surface for connection. CONSTITUTION:A tunnel is constructed toward an existing tunnel 2 having a shield machine 1 positioned at the head and is dug ahead having a cover ring 12 enclosed in a shield machine 1 and an over cutter 16 in the state of protrusion. When the cutter part 14 of the shield machine 1 approaches the existing tunnel 2, the over cutter 16 is enclosed in the cutter part 14. In addition, when the cover ring 12 is penetrated into the ground in the state of protruding toward the peripheral surface of the existing tunnel 2, the entire front surface 13 is adhered to the outer peripheral surface of the existing tunnel 2 so as to shield the entire surface. As a result, a connecting tunnel 4 is connected to the side of the tunnel 2, and this can be operated even at the bottom of the sea.

摘要： PURPOSE:To perform smooth formation of a curve having a small radius, by a method wherein an annular end plate is brought into contact with the inside of a tail plate and freely movable in a circumferential direction in an annular box. CONSTITUTION:An inner form 5 is annularly positioned at the rear of the inside of a shield excavator 4. The shield excavator 4 is advanced by exerting a reaction force on the inner form 5. Outflow of concrete 7 from the end side is blocked by means of a press ring formed with an annular box 3 and an annular end plate 8. The annular end plate 8 is brought into contact with a tail plate 41 and is freely movable in the annular box 3 to perform normally complete blocking of the end side.

摘要： PURPOSE:To enable the generation of a reaction force required for reliable propelling of a shield excavator, by a method wherein the tip of the expandable rod of a jack for propulsion brought into circumferentially slidable contact with the surface. CONSTITUTION:An inner form 5 is annularly positioned at the rear of the inside of a shield excavator 4. The shield excavator 4 is advanced by generating a reaction force at an inner form 5. The tip of the expandable rod of a jack 42 for propulsion is brought into circumferentially slidable contact with the surface on the facing side of a thrust transmission form 51. Outflow of placed concrete 7 from the end side is blocked through the force of a spring formed with an annular box 3 and an annular end plate 8. The placed concrete 7 is pressurized through a press ring by means of a press jack 6, and even after removal of the press ring, the concrete 7 is continued to be pressurized by means of a pressure hold ring 1.

CONSTITUTION:An excavator 2 is constituted of lining sections 8 and enlargement sections 10. Four enlargement sections 10 are formed. The excavator excavates underground, and an internal bedrock 20 and an external bedrock 22 are formed. With the excavation, segments 24 are assembled in the enlargement sections 10, and working shafts 30 in which workers can work are formed. By using the working shafts 30, lining bodies are formed in the lining bodies 8 by lining members (such as concrete), and built-up work of the working shaft of the following continuous enlargement section is executed. In addition, the working shaft 30 is used for the cleaning of the lining section, sludge withdrawal, power water supply, earth withdrawal of the internal bedrock, provision of various equipments and pipe lines, etc.
