摘要： PROBLEM TO BE SOLVED: To grasp the properties of the natural ground in front of a shield machine.SOLUTION: First and second through-holes 14, 15 are formed in a cutter face plate 4 and a shield partition wall 5 of a shield machine 1, respectively. A sediment sampling device 20 includes a mouth device 30, a horizontal boring device 50 for making a boring pipe 40 rotate and advance, an air swivel 60, and a sediment recovery system 70. The boring pipe 40 is a double-pipe and has a first flow path (a space between an outer pipe and an inner pipe) and a second flow path (a space in the inner pipe). The boring pipe 40 is inserted through the mouth device 30 and the first and second through-holes 14, 15 and the tip part of the boring pipe 40 is made to protrude from the cutter face plate 4 into the natural ground in front of it, while the rotation of the cutter face plate 4 is stopped. In this state, a liquid is supplied into the first flow path and the liquid is discharged from the tip part of the boring pipe 40. Thereby, excavated sediment in the vicinity of the tip part of the boring pipe 40 is allowed to flow to the second flow path and is recovered by a sediment recovery system 70.
摘要翻译：要解决的问题：掌握屏蔽机前面的自然地面的性质。解决方案：第一和第二通孔14,15形成在屏蔽机1的切割面板4和屏蔽分隔壁5中，分别。沉淀物取样装置20包括口装置30，用于使镗管40旋转并前进的水平镗孔装置50，空气回转件60和沉淀物回收系统70.镗管40是双管，并且具有第一流路（外管和内管之间的空间）和第二流路（内管的空间）。钻孔40通过口装置30插入，第一和第二通孔14,15和镗管40的顶端部分从刀面板4突出到其前面的自然地面中，同时切割面板4的旋转停止。在这种状态下，向第一流路供给液体，从镗孔40的前端排出液体。由此，允许在镗孔40的顶端部附近的挖掘的沉积物流向第二流路并由沉淀物回收系统70回收。

摘要： PROBLEM TO BE SOLVED: To improve construction efficiency by concretely recognizing characteristics of the natural ground in front of a shield machine and reflecting them to construction conditions of a tunnel construction.SOLUTION: When setting boring conditions of a shield machine, boring by the shield machine is stopped in step S1. Sampling of sediment of the natural ground in front of the shield machine is performed by using a sediment sampling device in step S2. Properties (particle size distribution characteristics or water permeable characteristics) of the sampled sediment and a division thereof are determined in step S3. Setting of the boring conditions of the shield machine is performed on the basis of the properties and the division of the sediment determined in step S4 in step S4. Concretely, kind, property, and injection ratio of a mud-added material injected into a cutter chamber when boring by the shield machine, an earth pressure in the cutter chamber when boring by the shield machine, and a boring advancing speed of the shield machine are set as the boring conditions.
摘要翻译：要解决的问题：通过具体识别盾构机前面的自然地面的特性，并将其反映到隧道施工的施工条件，提高施工效率。解决方案：设置屏蔽机的镗孔条件时，屏蔽机镗孔在步骤S1中停止。通过在步骤S2中使用沉淀物取样装置对屏蔽机前面的天然地面的沉积物进行采样。在步骤S3中确定取样沉淀物的性质（粒度分布特性或透水特性）及其分离。基于在步骤S4中的步骤S4中确定的沉积物的性质和划分来执行屏蔽机器的钻孔条件的设定。具体来说，通过屏蔽机进行镗孔时注入到切割机室中的泥浆添加物质的种类，性质和喷射比例，盾构机镗孔时切割室内的土压力以及屏蔽机的镗孔进给速度被设定为无聊的条件。

摘要： PURPOSE:To provide sufficient strength, durability, and water sealing property and further make it possible to meet a requirement that a shield excavation construction work can be performed at a high speed. CONSTITUTION:According to a method and device for jointing shield segments, a tip cone 22 is inserted into a joint male part 16 provided at the end of an anchor bar 14 of a shield segment 12 to be joined. The cone 22 is inserted into a joint female part 24 which is mounted to a shield segment 10 having been installed and has an opening 26 having large diameter larger than the outer diameter of the part 16 through the opening 26 until the cone 22 contacts an insertion stopper plate 30. The male part 16 is inserted further into the female part 24 so that fixing vanes 20 at the end cone 22 of the male part 16 are expanded radially outwardly RO along the cone 22, whereby the joint male part and the joint female part are connected together by means of a differential adjusting plate 28.
