摘要： PURPOSE:To increase workability significantly by eliminating forms for applying concrete and reducing related work, by eliminating assembling and installation of concrete reinforcing bars and by reducing competitive work at working faces, and provide possibility of making the thickness of concrete covering layer smaller and possibility of free selection of type of concrete to be used. CONSTITUTION:A work covering metal body 1, is used in which the inner form surfaces of a metal form 2 made of steel material or the like are closed with metal plates 3 made of iron or the like. The work covering metal body is attached to a skin plate 22 of a shield excavator, and a concrete filling portion 24 is formed by closing the outer open surfaces of the work covering metal body with the skin plate. The concrete filling portion is filled with concrete, and the shield excavator is driven so as to open the concrete filling portion and supply concrete into natural ground with pressure.

摘要： PURPOSE:To improve efficiency of work execution by a method wherein steel panels of hollow double-walled structure formed of an inner and an outer steel plates and steel ribs are connected with one another, being kept afloat in muddy water with buoyancy given thereto, at their right and left and upper and lower ends, and are sunk with additional connections further made thereto. CONSTITUTION:A steel panel 1 is formed in a double wall structure having hollow space therein, and a box-shaped member 6 is formed therein of an inner steel plate 3, an outer steel plate 4 and a plurality of steel ribs 5 that are provided between the inner and the outer steel plates. The box-shaped member 6 is given buoyancy with lightweight filling agent filled therein or with a hollow part 10 formed therein. The steel panels 1 are then connected with one another by welding or the like applied to each of the ends on the right and the left and on the upper and the lower parts of the steel plate 4, while the panels are kept afloat in muddy water 13 in an excavated ditch. The panels 1 are then sunk with additional panels connected further to the right and the left and to the upper and the lower positions thereof, and a steel double wall body in desired shape is formed therewith as the sinking reaches a specified depth. After this, concrete is cast into a space between the outer periphery of the double wall body and the inner wall of the excavated ditch, or the muddy water in the space is solidified. Thereby a space necessary for execution of work can be made small.

摘要： PURPOSE:To shorten term of works by a method wherein an excavator for excavation of station sections including platform sections and excavators for excavation of track sections are connected and assembled into a compound excavator in a starting vertical shaft, and excavation is made first for the station section and for the track section afterward. CONSTITUTION:Excavation is made either for a station section or a track section with two track excavators 2, 2', each equipped with a pair of self-rotating, whole- sectional-area-covering cutters 3, 3', and tunnels in circular section are excavated therewith. A tunnel in dumbbell-shaped section is excavated with a station excavator 1 equipped with a plurality of small, fixed self-rotating cutters 4 and a plurality of cutters 5 that are movable for a short distance, so that the excavation can be made between the two tunnels without overlapping with the excavation made with the excavators 2, 2'. A station section A is excavated first with an excavator that is made by combining the excavators 1, 2, 2' into one unit. After this, the excavator 1 is stopped and fixed, then the excavators 2, 2' are started again independently of the excavator 1 for excavation of a track section B. Thereby term of works can be shortened with an integrally compounded excavator.
