摘要： PROBLEM TO BE SOLVED: To provide a shield pipe jacking system and a shield pipe jacking method, by which labor saving and a reduction in cost can be attained in the case of the conduction of long-distance pipe jacking. SOLUTION: In the shield pipe jacking system in which long-distance pipe jacking longer than a fixed distance is conducted, an adjusting tank 4 as a part of a facility for forwarding forwarding slurry and a primary treatment facility 40 as a part of a facility for discharge treating discharging slurry are installed to a midway shaft 300 mounted in a path from a starting shaft 100 to a pipe-jacking spot, the forwarding slurry is forwarded towards the pipe- jacking spot through a slurry forwarding pipe 50 from the adjusting tank 4, and discharging slurry forwarded through a slurry discharging pipe 52 from the pipe-jacking spot is treated by the primary treatment facility 40.

摘要： PROBLEM TO BE SOLVED: To provide an excavator capable of favorably excavating natural ground including a bed rock stratum and a cohesive soil stratum and discharging excavated soil in a favorable condition without retension of soil in an excavated soil chamber. SOLUTION: An excavated soil chamber 7 is constituted of a peripheral wall 1a composed of a cutter head 4, a partition wall 5, and a part of a shield machine body at the front end of the shield machine body 1. A cone rotor 9 and an agitator blade driven by electrical motors are arranged at the lower part of the excavated soil chamber 7. A funnel-shaped crushing wall is formed at the periphery of the cone rotor 9 to form an agitation chamber. A discharge opening is formed in the vicinity of the basal end of the cone rotor 9 and connected to a mud discharge pipe 12. A plurality of protrusions 21 are formed on the peripheral wall 1a of the excavated soil chamber 7 and a crushing blade 22 positioned opposite to the protruded pieces 4c and spaced apart by a specified distance from the protruded pieces 4c is formed on the arm 4c of the cutter head 4. The crushing blade 22 is rotted in accordance with the rotation of the cutter head 4. When gravels are caught by the protruded piece 4c, shocks are given to the gravels to crush them.

摘要： PROBLEM TO BE SOLVED: To provide an excavation control system for cutting and excavating the natural ground in a specific size. SOLUTION: There is provided a shield machine which has a cutter head 22 on which leading bits 10 to 77, leading bits 80, and tailing bits 90 are arranged in order to cut and excavate the natural ground in a specific size. The leading bits 70 to 77 and the leading bits 80 carry out preliminary excavation at almost regular intervals, wherein the leading bits 70 to 77 are frontward and rearward movable, whereas the leading bits 80 are fixed to the cutter head 22. The tailing bits 90 cut and excavate natural ground convex portions between the preliminary excavated portions over several times by dividing the excavated portions into several blocks. The shield machine controls the rotational speed of the head cutter 22, based on a set depth of cutting and excavation and the speed of a jack.
