SOLID SPLITTING DISMANTLING METHOD USING EXPANSION TUBE AND DISMANTLING REMOVAL METHOD OF REINFORCED CONCRETE SLAB OF BRIDGE
PROBLEM TO BE SOLVED: To provide a solid splitting dismantling method using an expansion tube and a dismantling removal method of a reinforced concrete slab of a bridge, the expansion tube that reduces generation of noise and risk of environmental pollution, can safely perform dismantlement in a short time and can reduce a dismantling cost.SOLUTION: A solid splitting dismantling method is provided in which an existing solid such as an existing concrete construction and a block field is split, and is finely divided and dismantled. The solid splitting dismantling method includes: a coring step of drilling multiple core holes at predetermined intervals along the break line for dividing and breaking the existing solid; an expansion tube inserting step of inserting the expansion tube expanded by a fluid press-fitted inside in each core hole of the multiple core holes; and an expansion tube expansion step of press-fitting fluid to the multiple expansion tubes inserted into the multiple core holes and inflating the tubes, and making the existing solid split along the break line.SELECTED DRAWING: Figure 11
【課題】騒音の発生や環境汚染のおそれが少なく、安全に短時間で解体することができて解体費用を低減することができる膨張管を用いた固体の割裂解体工法及び橋梁の鉄筋コンクリート床版の解体撤去工法を提供する。【解決手段】既設コンクリート構造物や岩塊などの既存固体を割裂させて細かく分け解体する固体の割裂解体工法であって、前記既存固体を分割破断する破断線に沿って所定間隔を空けて複数のコア孔を削孔するコア抜き工程と、内部に流体が圧入されることで膨張する膨張管を前記複数のコア孔の各コア孔に挿置する膨張管挿置工程と、前記複数のコア孔に挿置された複数の前記膨張管に流体を圧入して膨張させ、前記破断線に沿って前記既存固体を割裂させる膨張管膨張工程と、を備える。【選択図】図１１
