Cyclic auxiliary excavating device for open caisson excavation
The invention relates to the technical field of open caisson excavation, and discloses an open caisson excavation itinerant auxiliary excavation device which comprises a mounting unit and an excavation unit, the mounting unit comprises a supporting part, a matching sleeve and a driving assembly, the supporting part is fixedly connected with the matching sleeve, and the driving assembly is arranged at the top of the supporting part; the driving assembly is coaxially matched with the supporting part; the excavating unit comprises a main shaft, a protective shell and an excavating part, the main shaft penetrates through the interior of the protective shell, the main shaft is coaxially matched with the protective shell, and the excavating part is coaxially matched with the main shaft. According to the open caisson excavation device, the original tamped soil in the open caisson sinking process is excavated, meanwhile, the two symmetrical sides of an open caisson are evenly stressed through rotary excavation, the sinking stability of the open caisson is guaranteed, and meanwhile the sinking efficiency of the open caisson is guaranteed.
本发明涉及沉井挖掘技术领域，公开了一种沉井挖掘巡回辅助挖土装置，包括安装单元和挖掘单元，所述安装单元包括支撑部、配合套和驱动组件，所述支撑部与配合套固定连接，所述驱动组件设置于支撑部顶部，所述驱动组件与支撑部同轴心配合；所述挖掘单元包括主轴、保护壳和挖掘部，所述主轴贯穿保护壳内部设置，所述主轴与保护壳同轴心配合，所述挖掘部与主轴同轴心配合，本发明的有益效果是：通过挖掘单元在沉井底部进行旋转挖掘运动，将原本沉井下沉过程中被夯实的土质进行挖掘操作，同时旋转挖掘使沉井对称的两边受力均匀，保证了沉井下沉的稳定性，同时保证了沉井下沉的效率。
