DISMANTLING METHOD OF EXISTING UNDERGROUND FRAMEWORK
PROBLEM TO BE SOLVED: To provide a dismantling method of an existing underground framework capable of shortening the construction period of dismantling work of existing underground frameworks.SOLUTION: A dismantling method of an existing underground framework comprises a step S1 of building a pair of first retaining walls 40X opposed to each other and a pair of second retaining walls 40Y that are provided substantially perpendicular to the first retaining wall 40X and opposed to each other in an existing underground framework 20, a step S2 of dismantling the existing underground framework 20 to the depth of a first stage cutting beam 41, a step S3 of bridging a cutting beam 41Y between the second retaining walls 40Y, a step S4 of dismantling the existing underground framework 20 to a predetermined depth, leaving a remaining framework 50A, wherein a portion of the existing underground framework 20 that is in contact with the first retaining wall 40X inside the first retaining wall 40X is defined as the remaining framework 50A, and a step S5 of bridging a cutting beam 41X between the first retaining walls 40X.SELECTED DRAWING: Figure 2
【課題】既存地下躯体の解体工事の工期を短縮できる既存地下躯体の解体方法を提供すること。【解決手段】既存地下躯体の解体方法は、既存地下躯体２０の内部に、互いに対向する一対の第１の山留め壁４０Ｘと、第１の山留め壁４０Ｘに略直交して設けられて互いに対向する一対の第２の山留め壁４０Ｙと、を構築するステップＳ１と、既存地下躯体２０を１段目の切梁４１の深さまで解体するステップＳ２と、第２の山留め壁４０Ｙ同士の間に切梁４１Ｙを架設するステップＳ３と、既存地下躯体２０のうち第１の山留め壁４０Ｘの内側でかつ第１の山留め壁４０Ｘに当接する部分を残置躯体５０Ａとし、残置躯体５０Ａを残して所定深さまで解体するステップＳ４と、第１の山留め壁４０Ｘ同士の間に切梁４１Ｘを架設するステップＳ５と、を備える。【選択図】図２
