SUCTION SUBSTRUCTURE
To provide a suction substructure that can be easily removed by pouring water even when a filler is thinned and injected at the time of installation.SOLUTION: A suction substructure 1 having a top slab 3 and a skirt 4, comprises: an installation drain pipe 5 communicating with a defined area A defined by the top slab 3, the skirt 4, and an underwater ground; a filling pipe 7 for filling the defined area A with a filler G in an installed state in which the skirt 4 is sunk to a predetermined depth of the underwater ground; and a removal water injection pipe 6 protruding downward from the lower surface of the top slab 3 so that a tip thereof penetrates the underwater ground in the installed state. A plurality of water injection holes are formed on the peripheral surface of the removal water injection pipe 6 that penetrates into the underwater ground in the installed state. The water injection hole is provided with a clogging prevention member having a function of preventing intrusion of earth and sand into the pipe while ensuring water permeability from inside the pipe to outside the pipe.SELECTED DRAWING: Figure 2
【課題】設置時に充填材を間詰め注入しても、注水によって簡単に撤去することができるサクション基礎構造体を提供する。【解決手段】頂版部３と、スカート部４とを備えたサクション基礎構造体１であって、頂版部３、スカート部４及び水底地盤によって画成された画成領域Ａに連通された設置用排水管５と、スカート部４を水底地盤の所定深度まで沈設した設置状態において、画成領域Ａに充填材Ｇを間詰め注入する充填管７と、頂版部３の下面から下方に向け、設置状態において先端が水底地盤に貫入される長さで突出した撤去用注水管６とを備え、設置状態において水底地盤に貫入される撤去用注水管６の周面には、複数の注水孔が形成され、注水孔には、管内から管外への通水性を確保した状態で、管内への土砂の侵入を防止する機能を有する目詰まり防止部材が設けられている。【選択図】図２
