摘要： PROBLEM TO BE SOLVED: To provide an apparatus for spreading the width of an existing tunnel, which enables safe width-spreading work in a short construction period while keeping the tunnel in service conditions. SOLUTION: The apparatus is formed of a protector 2 which has its inner space penetrated in a tunnel axial direction, and a movable work frame 3 which is shorter in length in the tunnel axial direction than the protector and arranged astride the protector. The work frame is movable in the tunnel axial direction independently from the protector. Alternatively, the protector may be movable in the tunnel axial direction independently from the work frame.

摘要： PROBLEM TO BE SOLVED: To provide a structure of and a construction method for an underground cavity that can ensure sufficient and reliable reinforcement or water sealing even if a spiral tunnel has a wide interval. SOLUTION: A cavity is constructed in the ground. A spiral tunnel is constructed about the underground cavity in an encircling relation thereto. A connecting hole is constructed from one position of the spiral tunnel to another. A reinforcement or sealant is placed into the ground from the connecting hole. The cavity is alternatively constructed after the reinforcement or sealant is placed from the connecting hole. Both are alternatively constructed simultaneously.

摘要： PROBLEM TO BE SOLVED: To provide a three-dimensional investigation method for bearing force power of the soil by which the structure in a certain range of underground can be precisely and three-dimensionally analyzed. SOLUTION: A spiral tunnel 1 is constructed so that a certain range of section in the underground is surrounded. And an amplifier 2 is installed in the point where the excavation has been completed. The amplitudes generating at the cutting face of the spiral tunnel under excavation are received by the receiver 2. And the ground characteristic in the area surrounded by the spiral tunnel 1 is analyzed. In this case, this can be performed by constructing the spiral tunnel 1 at the periphery of the cavity 4.

摘要： PROBLEM TO BE SOLVED: To provide a casting method for a stream tunnel that effectively utilizes a carrying device of a stream tunnel pipe, thereby improving work efficiency and achieving facility cost reduction.SOLUTION: At an assembly site A away from a casting place B where a stream tunnel 10 in which a pipe 7 is embedded in concrete 10a is casted, a plurality of partition walls 8 are assembled together at an outer peripheral part of a falsework material 5 supported in advance by a mount 4 on a truck 3 to form a follow-on pipe 7. The truck 3 is moved from the assembly site A to the casting plate B together with the mount 4 and falsework material 5 along a rail 2. An end part 7a of the follow-on pipe 7 is connected to an end part 7b of the pipe 7 of a preceding stream tunnel 10 that is already installed in a casting place B. The concrete is fed to a casting chamber provided between the follow-on pipe 7 and a formwork arranged around the follow-on pipe 7 to cast the follow-on stream tunnel in which the follow-on pipe 7 is embedded in the concrete. The truck 3 is returned to the assembly place A from the casting site B together with the mount 4 and falsework material 5 along the rail 2. The falsework material 5 is separated from the pipe of the follow-on stream tunnel, and then the follow-on stream tunnel is connected to the preceding stream tunnel 10. By the present invention, work efficiency is improved and facility cost is reduced.
