摘要： PROBLEM TO BE SOLVED: To stop in a minimum time the oscillation of a hanging load such as a bucket hanging from a traversing trolley, during acceleration or deceleration. SOLUTION: The operating block of the traversing trolley 8 is divided into an accelerated traversing block, a constant-speed traversing block and a decelerated traversing block. In the accelerated traversing block, the travel speed of the traversing trolley 8 is controlled continuously at a constant acceleration along a secondary function curve of the travel speed to the distance traveled, and the traversing trolley shifts to constant-speed traversing when the oscillation of the bucket 18 caused at startup finishes one cycle of pendulum motion. In the constant-speed traversing block, the traversing trolley 8 is traversed at constant speed so that there is no relative speed difference between the traversing trolley 8 and the bucket 18. In the decelerated traversing block, the travel speed of the traversing trolley 8 is continuously controlled at a constant deceleration along a secondary function curve of the travel speed to the distance traveled, this control being stopped when the oscillation of the bucket 18 caused during the shift to the decelerated traversing finishes one cycle of pendulum motion.

摘要： PROBLEM TO BE SOLVED: To provide a method for executing a core material for earth retaining capable of easily conducting the pull-out works of the core material at a low cost without having an effect such as noises, vibrations or the like on peripheral environment even in earth retaining having large depth. SOLUTION: The surfaces of the core materials 1 for earth retaining are covered previously with bentonite sheets 2, and the bentonite sheets are supplied with water by a water spray or the like and the core materials 1 are built in the case of the execution of works of earth retaining. Since frictional force between the core material built into a ground and a pit wall is relaxed by a mud-like bentonite by previously supplying water and swelling bentonite, the core material can be pulled out easily by multi-pully pull-out using a crane or the like in the case of core-material removal after the execution of works of earth retaining.
