Open caisson mode and bottom shaft rotary excavating device
The invention discloses an open caisson method and a bottom shaft rotary excavating device.The open caisson method comprises the steps that a rotary blade foot is placed at the lower end of an open caisson body, an impact sleeve in the open caisson body is placed on the lower side of a striking head, a driving assembly is placed on the upper side of a second gear ring, and a first rotary gear and a second rotary gear are meshed with the second gear ring; a rotating shaft gear at the end of a vertical rotating shaft on the lower side of the transverse rod is meshed with an excavating gear on the side edge of the supporting plate, the excavating gear drives a first gear ring to rotate, so that a rotating blade foot rotates, and meanwhile a driving assembly drives a striking head to hammer an impact sleeve to obtain downward shaking force. The device has the beneficial effects that a downward continuous striking force is provided in the rotary excavation process of the open caisson blade foot, and the striking force does circular motion all the time, so that uniform distribution of the force is realized, and the open caisson can settle quickly and is firmer.
本发明公开了一种沉井方法及底轴旋转挖掘装置，包括在沉井体下端放置旋转刃脚，将沉井体内部的冲击套放置在击打头下侧，将驱动组件放置在第二齿圈上侧，使第一旋转齿轮和第二旋转齿轮与第二齿圈啮合，横杠下侧的竖直转轴端部的转轴齿轮与支撑板侧边的挖掘齿轮啮合，挖掘齿轮带动第一齿圈旋转，使得旋转刃脚旋转，同时驱动组件带动击打头锤击冲击套获得向下的震动力，本发明的有益效果是：在沉井刃脚旋转开挖的过程中提供一个向下的连续不间断的击打力，且击打力始终做圆周运动，实现了力的均匀分布，能够使得沉井快速沉降且更加牢固。
