REMOVAL METHOD OF BURIAL STRUCTURE
PROBLEM TO BE SOLVED: To provide a removal method of a burial structure capable of easily and safely removing an existing structure by reducing labor and by shortening a construction period.SOLUTION: A removal method includes a carrying-in process of carrying in a cutting device 1 having a cutting edge member 5 in a hollow existing structure 3 buried underground and composed of reinforced concrete, a cutting process of cutting the existing structure 3 by the cutting edge member 5 by advancing the cutting edge member 5 of the cutting device 1 carried in the existing structure 3 in the carrying-in process, a moving process of moving the cutting device 1 to the next uncut position from a position of cutting the existing structure 3 in the cutting process by retreating the cutting edge member 5, a crushing process of crushing the existing structure 3 by repeating cutting operation in the cutting process and moving operation in the moving process, and a carrying-out process of carrying out a crushing object of the existing structure 3 crushed by the crushing process onto the ground.SELECTED DRAWING: Figure 1
【課題】 工期を短縮し、労力を削減して、容易かつ安全に既設構造物を撤去することができる埋設構造物の撤去方法を提供する。【解決手段】 地中に埋設され、鉄筋コンクリートから成る中空の既設構造物３内に、切刃部材５を備える切断装置１を搬入する搬入工程と、搬入工程で既設構造物３内に搬入された切断装置１の切刃部材５を前進させて、切刃部材５によって既設構造物３を切断する切断工程と、切断装置１を、切刃部材５を後退させて、前記切断工程で既設構造物３を切断した位置から次の未切断位置へ移動させる移動工程と、切断工程における切断動作と前記移動工程における移動動作とを繰り返して、既設構造物３を破砕する破砕工程と、破砕工程で破砕された既設構造物３の破砕物を、地上へ搬出する搬出工程とを含む。【選択図】 図１
