TUBING DEVICE AND STAGE FORMING METHOD FOR TUBING DEVICE
To provide a tubing device provided with a working stage, allowing removal of stage plates corresponding to a plurality of manufacturing diameters to be easily performed, and transportation and storage in a limited space, and a stage forming method for the tubing device.SOLUTION: A tubing device 11 is provided with an opening 19 having an inner diameter corresponding to an inner diameter of a casing insertion hole 17 in a working deck 20, wherein the opening has respective inner diameters corresponding to a plurality of outer diameters of casing tubes and is detachably provided with a working stage 39 holding a plurality of annular stages 36, 37, 38 with different inner and outer diameters, respectively, as a set in a sequentially stacked nest state from a larger one to a smaller one in inner and outer diameters. Further, lifting parts 36j, 37j, 38 for lifting, are provided on upper surfaces of annular stages, respectively.SELECTED DRAWING: Figure 3
【課題】複数の施工径に対応した足場板の着脱を容易に行え、かつ、省スペースで輸送、保管することができる作業用足場を備えたチュービング装置及びチュービング装置の足場形成方法を提供する。【解決手段】チュービング装置１１は、作業デッキ２０にケーシング挿通孔１７の内径に対応した内径を有する開口部１９を備え、該開口部に、ケーシングチューブの複数の外径にそれぞれ対応した内径を有し、かつ、互いに内外径の異なる複数の円環状足場３６，３７，３８を一組として、これを内外径の大きいものから順次入れ子状に重合保持する着脱可能な作業用足場３９を設けている。また、各円環状足場の上面には、吊り上げ用の吊り部３６ｊ，３７ｊ，３８ｊがそれぞれ設けられている。【選択図】図３
