    • PROBLEM TO BE SOLVED: To provide drill/stir bits of an underground pile formation and a ground improvement method making use thereof capable of facilitating the excavation irrespective of N-value of a soft ground to promote working performance by increasing a mixing function between excavated soil and cement milk to be injected after the excavation and forming an underground pile with high density.
      SOLUTION: The underground pile is so formed that at least two twisted blade type bits 14 are radially arranged to provide a plurality of stages of the bits to a leading conduit section 11' of a tubular rod 11 equipped with an introduction pipe of injection fluid and provided with torque in a successively connectable manner, an envelope described by each outer end of the blade type bits 14 is formed in a tapered shape toward the front end, the drill/stir bits 10 providing injection nozzles 17 and 20 of the fluid connected to the introduction pipe to the front end section and at least one stage of the blade type bits in the direction of a radius are used to drill and stir while injecting pressure fluid and that a stirring operation is executed while injecting a high-pressure air and the cement milk in the case of reverse operation.

    • PROBLEM TO BE SOLVED: To provide a bicycle parking system in which a bicycle can be parked in and taken out easily only by moving a little bicycles even when the bicycle parking system has a large bicycle parking area and tens of bicycles can be parked therein.SOLUTION: A bicycle parking system comprises a slider 24 provided in each support rack 16 and mounted to a slide rail 12 movably, a rail-side stopper 14 provided at a predetermined interval in the slide rail 12, and a slider-side stopper 26 provided in the slider 24 and abutted to the rail-side stopper 14 with the movement of the slider 24. In the state where support racks 16 positioned at both sides of a specific support rack 16 are moved away from the specific support rack 16, respectively, and the movement of the support racks 16 at both sides is regulated by abutting the slider-side stopper 26 to the rail-side stopper 14 or abutting the slider 24 to a slider 24 of any other support rack 16, a clearance sufficient for parking in/taking out a bicycle 80 is constituted between the support racks 16 at both sides.
    • 要解决的问题:提供一种自行车停放系统,其中即使当自行车停放系统具有大的自行车停放区域并且可以停放数十辆自行车时,自行车也可以通过移动小型自行车而容易地停放和取出。 解决方案:一种自行车停放系统,包括设置在每个支撑架16中的滑动件24,并且可移动地安装在滑轨12上,在滑轨12中以预定间隔设置的轨道侧止动件14和设置在滑轨侧止动件26 在滑块24中,随着滑块24的移动而与轨道侧止动件14抵接。在位于特定支撑架16的两侧的支撑架16分别从特定的支撑架16移开的状态下, 并且通过将滑块侧止动件26抵接到轨道侧止动件14或将滑块24邻接到任何其他支撑架16的滑块24来限制支撑架16在两侧的运动,足够的停车空间 在两侧的支撑架16之间构成自行车80。
