摘要： PROBLEM TO BE SOLVED: To improve demolition efficiency. SOLUTION: An in-tunnel track 10 is constructed of a plurality of crossties 12 and a plurality of rails 14. In demolition and removal of the track 10, the track 10 is divided into track blocks 18 each having a plurality of crossties 12 connected by the rail 14. When the track 10 is divided into track blocks 18a-18n, the track block 18a located on the farthest position side from a tunnel entrance is removed first. In this removal, the track block 18a located on the farthest position side from the tunnel entrance is moved upward and then shifted toward the tunnel entrance side to be placed on a rail of another tack block 18b adjacent to the track block 18a, and the placed track block 18a is towed and moved along the rail 14. In this way, the divided track blocks 18a-18n are individually conveyed out sequentially to the outside of the tunnel.

摘要： PROBLEM TO BE SOLVED: To allow slime accumulated on a bottom of a pile hole to be efficiently discharged to the ground.SOLUTION: A slime processing device 1 includes a pump 2 sucking slime 35 accumulated on a bottom 27 within a pile hole 25 together with muddy water 36. The pump 2 is provided with a hood 15 so as to surround the pump 2. The hood 15 has an outer surface formed in a shape corresponding to the inner surface of the bottom 27 of the pile hole 25. Since the slime 35 in a portion corresponding to the inner side of the hood 15 is sucked and discharged, the slime 35 is not spread over a wide area within the pile hole 25 and the slime 35 accumulated on the bottom 27 of the pile hole 25 can be efficiently sucked and discharged to the ground.
摘要翻译：要解决的问题：使积聚在桩孔底部的泥渣有效地排放到地面上。解决方案：泥浆处理装置1包括泵2，其与泥浆水36一起吸收积聚在桩孔25内的底部27上的粘液35.泵2设置有围绕泵2的罩15。罩15具有形成为与桩孔25的底部27的内表面相对应的形状的外表面。由于与罩15的内侧相对应的部分中的粘液35被吸入和排出，所以粘液35 不会在堆孔25内的广泛区域上扩散，并且能够有效地将堆积在桩孔25的底部27上的泥土35吸引并排出到地面。版权所有（C）2013，JPO＆INPIT
