Steel pipe sheet pile, joint structure of steel pipe sheet pile, and wall structure as well as the pull-out method of steel pipe sheet pile

摘要

As for the steel pipe sheet pile of this invention, on the outside of the lagging itself and the aforementioned lagging itself which consist of the metal tubing, paralleling to the longitudinal direction of the aforementioned lagging, itself on opposite side to the 1st coupling and the aforementioned external aforementioned 1st coupling of the aforementioned lagging itself which are provided, paralleling to the longitudinal direction of the aforementioned lagging, itself the 2nd coupling which is provided and, to have, the aforementioned 1st and 2nd coupling to be laid out respectively alienating from the aforementioned 1st section on rear side of the 1st section and the aforementioned lagging itself which are laid out on front side of the coupling itself and the aforementioned lagging itself, aforementioned 1stWith the section to possess with the 2nd section which supports the aforementioned coupling itself, the aforementioned 1st and 2nd section respectively to be locked by the aforementioned lagging, itself in the aforementioned 1st coupling, paralleling to the longitudinal direction of the aforementioned lagging and itself be able to provide the 1st space where one end of the extending being present and the same longitudinal direction is blocked, in the aforementioned 2nd coupling, paralleling to the longitudinal direction of the aforementioned lagging and itself be able to provide the 2nd space where one end of the extending being present and the same longitudinal direction is blocked, the aforementioned 1st and 2nd section of the aforementioned 1st coupling block the aforementioned 1st space,And in the aforementioned 1st and 2nd section of the aforementioned 2nd coupling block the aforementioned 2nd space, from the aforementioned 1st and 2nd space directing to outside direction, the 1st injection hole in order to inject the compressed water is provided.
