摘要： PROBLEM TO BE SOLVED: To make it possible to recover an excavation device by mounting turnably a cutter head which is smaller than the inside diameter of a segment on a main body block and providing reducingly an over cutter capable of excavating the outside diameter of a cylindrical body which is larger than the outside diameter or the segment and a shield jack laid out near the inner periphery area of the cylindrical body in the inside diameter of the segment. SOLUTION: During excavation, an over cutter 31 is projected from the lateral side of a cutter head 30 and turned with a drive motor 32, thereby excavating the ground. A width expansion jack 41 is extended so that a shield jack 40 may be laid out near the inner peripheral surface of a cylindrical body 11, thereby moving forward the whole excavation device by using a segment 14 as a reaction force. When it is recovered, the over cutter 31 is pulled in, and the width expansion jack 41 is reduced so that the shield jack 40 may be housed in the segment 14 thereby removing a fixing material 22 between the cylindrical body 21 and a head segment 13 and pulling up the excavation device.

摘要： PURPOSE: To promote the automatic unmanned execution of temporary earth retaining work in a vertical shaft. CONSTITUTION: In a segment-form temporary earth guard plate 4, a bolt is automatically clamped to a support frame 11 of a feeder on the ground by a bolt clamping machine, whereby this plate 41 is fed to a connecting device 51. A connecting machine 53 is composed of a receiver device 66, a holding device 67, a transfer device 68, an axial clamping device 69, a circumferential clamping device, and an existing temporary earth guard plate expanding device. A connecting device 51 holds the supplied temporary earth guard plate 41, shifting to an objective position, and bolts are automatically clamped, assembling one ring. Further this connecting device 51 expands and contracts two vertical two-stage gripper devices 54 and 55 alternately, and expands a center shaft jack 56 and a connecting machine shifting jack 57 successively, going up and down in the axial direction.

摘要： PURPOSE: To allow the pipeline of an excavator to be extended easily. CONSTITUTION: A pipeline extended onto the ground from an excavator 1 is disposed movably along the wall surface of an excavated pit and fixed to a fitting plate 4 so as to be connected in the expandable or bendable state to the excavator 1. The fitting plate 4 is slidably engaged with a guide fixed to the wall surface of the excavated pit. A roller is disposed in a position opposed to the wall surface and suspended from the ground by a hanging rope 3, and the pipeline is extended on the ground according to the excavating depth of the excavator 1. The hanging rope 3 is extended to move the pipeline along the excavated pit so as to deliver the pipeline into the excavated pit.

摘要： PURPOSE:To save labor in works for excavation, earth-discharging and retaining and to improve safety by a method wherein outriggers and a steel tube are pressed against and fixed tight to the shaft wall and excavation is made with a bucket type excavator. CONSTITUTION:The entire body of equipment is hung down and installed in a shaft 17 that is excavated preliminarily to a specified depth from the ground surface 16. Outrigger jacks 2 and hydraulic jacks 5 are extended, and outriggers 1 and a steel tube 3 are pressed against and fixed tight to the shaft wall 18. Then, excavation is made with a bucket excavator 6 and at the same time, excavated earth is discharged by means of evacuation air pressure. Whenever the excavation reaches each of specified depths, the steel tube 3 is separated from the shaft wall 18 with the hydraulic jacks 5 contracted, and the entire equipment is lowered with a shaft guide 10 with the outrigger jacks 2 contracted. As the excavation proceeds, lining is made for retaining to the exposed parts of the excavated wall surface, and an earth-discharging pipe is extended successively with additions. By repeating the above-mentioned processes, a shaft in desired depth can be constructed.
