摘要： PROBLEM TO BE SOLVED: To provide an excavation method and the like capable of preventing deformation and depression of a cover plate and furthermore preventing intrusion of sediment and the like into an excavator when the roof excavator is preceded.SOLUTION: An excavation mechanism 1 has a main excavator 3 and a rectangular roof excavator 2 arranged on a top face of the main excavator 3. The rectangular roof excavator 2 has a roof machine box 25 which can be advanced by a roof propulsion jack 22 and a roof propulsion box 23 which accommodates a rear part 25b of the roof machine box 25. At a rear end of a front part 25a of the roof machine box 25, a cover plate 21 is attached so as to cover a top face and a side face of the roof propulsion box 23. An openable/closable hole part 232 is provided in a front end 23b of the roof propulsion box 23, and a filler 200 is injected through the hole part 232 into a space 20 which is formed inside the cover plate 21 and outside the rear part 25b of the roof machine box 25 when the roof machine box 25 is advanced.

摘要： PROBLEM TO BE SOLVED: To provide a thrust control method of an excavation mechanism with which excavation can be performed while stabilizing an attitude of the excavation mechanism.SOLUTION: In an excavation mechanism 1, two main body excavators 3 are arrayed in a horizontal direction, and each excavator 3 includes a cutter 31 that reciprocates and swivels in the horizontal direction. During excavation by the excavation mechanism 1, a thrust Pof a left jack group 41a is determined by increasing/decreasing thrust correction values L, Lcorresponding to a swiveling direction of each cutter 31 from a base thrust Xof the left jack group 41a and a thrust Pof a right jack group 41b is determined by increasing/decreasing thrust correction values R, Rcorresponding to the swiveling direction of each cutter 31 from a base thrust Xof the right jack group 41b, thereby canceling a reaction moment M applied to the excavation mechanism 1 with swiveling of the cutter 31.
