摘要： PROBLEM TO BE SOLVED: To provide a cutter-bit mounting structure and a cutter-bit maintenance method which can cope with the abrasion of the cutter bit without damaging a cutter head and equipment near the cutter head when the bit is worn out, and enable the replacement of the bit without making a worker get out to the face side of the cutter head when the abrasion of the bit has progressed. SOLUTION: When a bit body 10 is worn out by a predetermined amount, a rod 9 is protruded to a face side from a guide hole 8 by elongating a jack 11 depending on the amount of abrasion, so that the radius of cutting by the bit body 10 can be returned to a state before the abrasion. When the abrasion of the bit body 10 has further progressed, the jack 11 is contracted and separated from the rod 9 on the anti-face side of the cutter head 2, so that the rod 9 can be extracted from the guide hole 8, and the bit body 10 is replaced singly or integrally with the rod 9.

摘要翻译：要解决的问题：提供一种刀头安装结构和刀头维护方法，其可以在刀头磨损时克服刀头的磨损而不损坏刀头和设备附近的设备并且当钻头的磨损发展时，能够使钻头更换而不使工作人员离开刀头的正面。解决方案：当钻头体10磨损预定量时，杆9通过根据磨损量伸长千斤顶11而从导向孔8向正面侧突出，使得切割半径通过钻头体10可以在磨损之前返回到状态。当钻头体10的磨损进一步发展时，千斤顶11在刀头2的防侧面上与杆9收缩并分离，使得杆9能够从导向孔8中取出，钻头体10单独地或与杆9一体地替换。版权所有：（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a floor slab for a shield tunnel, which has superior structure and can be efficiently constructed.SOLUTION: A floor slab 200 comprises: a box culvert 200A which is installed at a central part in a width direction of a bottom part of the tunnel; and a pair of right and left concrete blocks 200B which are installed at both end parts in the width direction of the bottom part of the tunnel so as to sandwich the box culvert 200A. The concrete block 200B is divided into two portions of a lower member 203 and an upper member 204, and a face S2 at which the block 200B is divided is parallel. The concrete block 200B has a vertical face that faces a side wall part of the tunnel while having a void therebetween, and filling concrete 205 is cast in the void.

摘要： PROBLEM TO BE SOLVED: To provide a method and a system which can accurately measure earth removal volume nearby a cutting edge in shield excavation. SOLUTION: When earth removal loaded on a peak-end open conveyor 12 from the cutting edge and discharged in the shield excavation, facing-down shape measuring instrument 20 is provided above the path 11 of the conveyor 12, and measures the three-dimensional coordinates of the peak edge and loaded earth reception surface of the unloaded conveyor 12 and the three-dimensional coordinates of the peak edge and loaded earth surface of the conveyor 12 having been loaded with the waste earth. The volume of the loaded earth removable is computed, conveyor by conveyor, from the relative three-dimensional coordinates of the loaded earth reception surface and the relative three-dimensional coordinates of the loaded earth surface to the pack edge. Preferably, the weight of the conveyor 12 is measured before and after loading, and the weight of the loaded earth removal of each conveyor 12 is computed from the difference between the weight of the conveyor 12 before the loading and the weight after the loading. More preferably, the specific weight of the loaded earth removal of each conveyor 12 is computed from the volume and weight of the loaded earth removal.
