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 boring control method in a shield method capable of stabilizing the circumference of a shield tunnel with high degree of accuracy by surely deciding the necessity of its correction even if a wide area of the width in the excavated direction of the shield tunnel is excavated. SOLUTION: The total excavated amount equivalent to a plurality of ring parts excavated by a sludge type shield machine is obtained, and a bedrock around the sludge type shield machine is managed on the basis of the total excavated amount. As the total excavated amount, E1 is an excavated amount of one ring portion for a segment directly before the excavation is carried out, En is the total excavated amount of n ring portions (n is two or more integers), and when either one of the total excavated amounts E2 to En is in excess of predetermined threshold R2 to Rn set to each of the total excavated amounts E2 to En, the predetermined correction is carried out.

摘要： PURPOSE: To make it possible to use most effectively an inherent or remaining resisting ability of an existing structure itself as a double closing dike and construct in a short time or with a light weight machine, and further eliminate the need for a new site or space. CONSTITUTION: Internal filler soil 3 in a double closing dike 1 or an original ground area 4 in steel sheet piles 2 or sandwiched with the steel sheet piles 2 is ground-improved. Or new steel sheet piles 6 or steel pipe piles are placed outside an existing closing steel sheet pile or a steel pipe sheet pile of the double closing dike 1. The ground area between the existing closing steel sheet piles 2 or the like or the ground area between the existing closing steel sheet piles 2 and the new steel pipe sheet piles or both original ground areas 4 are ground-improved.
