摘要： PURPOSE:To separate a crane and reinforcement which has been set upright by crane operation, with the use of an on-ground work. CONSTITUTION:Each of three sheathing pipes 22 is formed therein with a main reinforcement insertion space 22s through which main reinforcement 37a that is steel reinforcement is inserted so as to be movable in its axial direction. A main reinforcement suspender 21 for suspending a clamp 27 adapted to grip the main reinforcement 37a, composed of a coupling member 23, a towing wire 25 and a bundling jig 26 which serve as suspending and engaging means, is attached to a hook block 41 of a crane vehicle 40. In a condition such that the main reinforcement 37a is inserted in the main reinforcement insertion space 22s, and is gripped by the clamp 27, the crane is operated to set the main reinforcement 37a upright. In this condition, when the clamp 27 is released to lift up the hook block 41, the sheathing pipe 22 comes off from the main reinforcement.

摘要： PURPOSE:To increase safety and work efficiency in the erection of reinforcements. CONSTITUTION:Five main reinforcements 6 are lifted and suspended by a crane one at a time in such forms that these main reinforcements 6 are arranged correspondingly over the connection position P1 of the existing main reinforcements 6 and also that the vertical distances H1 to H5 between the lower end 6b of these reinforcements 6 and the connection position P1 corresponding to the lower end 6b are different from each other. Also the five suspended main reinforcements 6 are lowered while they are guided facing toward their respective connection position P1 until they reach their respective connection positions P1 one by one in order. Then the main reinforcements reached 6 are connected one by one in order to the existing corresponding main reinforcements 6.

摘要： PURPOSE:To enhance the safety of excavation and lining work and further improve the efficiency of construction work at the same time. CONSTITUTION:A ground support frame 19 to which an outer peripheral gable stopper material 25 and a gable face plate 28 are installed to the end on the side of a pit mouth, is developed in front of a cutting face and the frame 19 is raised by way of an expansion support leg 22, thereby timbering a pit wall with an outer shell 20 and suppressing an unstable natural ground. When a tunnel lining form 5A is laid out in a temporary timbering device 5 on the pit mouth side so that a gable presser board 16 and the gable face plate 28 may be connected as opposed, a lining space is shielded and formed in such a fashion that the outer peripheral stopper material 25 and the gable face plate 28 may serve as a gable stopper. It is, therefore, possible to place lining concrete immediately.

摘要： PURPOSE:To execute excavation work safely in a caisson type foundation vertical hole by using caisson type foundation construction machine equipped with a hanger frame on a self-running frame capable of freely running on the ground and to make it possible to execute the excavation work efficiently in a plurality of caisson type foundation vertical holes so as to complete the work at a time. CONSTITUTION:In a caisson type foundation excavation construction method executed by using a caisson type foundation construction machine equipped with a hanger frame on a self-running frame 2 capable of freely running on the ground, a composite construction device 7 is suspended into a composite vertical hole bringing earth moving work to completion from the center and vicinity of the self-running frame by a winch 5 provided on the self-running frame of the caisson type foundation construction machine. After that, an excavator provided to a composite construction device is used to execute trimming work of a projection of an excavation surface in the vertical hole. Then, a wall shoring device provided to the composite construction device is used to execute shoring work of an excavated wall surface, and a drill provided to the composite construction device is selected to bore for a blasting hole, etc.

摘要： PURPOSE:To enable a small bore propelling device to cope with a rock bed or the like by providing rotatably a cutting face plate formed in a part with an opening on a tubular member provided removably on the front end of a propelling pipe and providing a hitting bit movable back and forth in the opening section. CONSTITUTION:A face plate 2 of a small b ore propelling unit is provided with four slits 6 around which a plurality of cutter bits 7 are provided to cut earth layers to transport muck through the slits 6 to a chamber 5 and expell it to the outside. Next, an opening 8 is formed between adjacent slits 6 of the face plate 2 and a hitting bit 9 is disposed movably back and forth between the advance and retreat positions. Next, the hitting bit 9 is connected to a vibrating machine 10 fixed to a support member 3 and operated by the vibration of the vibrating machine 10 to crash a rock bed or the like by hitting. The hitting bit is rotated together with the rotating face plate 2 to excavate the front face of a facing so that both normal earth and rock bed can be most effectively excavated.
