The invention provides an open caisson construction auxiliary device and a construction method. The open caisson construction auxiliary device comprises a center shaft, a truss, a center drill bit fixed to the lower portion of the center shaft and auxiliary drill bits fixed to the truss and distributed around the center drill bit. The truss is further provided with an axial position early warning device, and the axial position early warning device is used for conducting real-time monitoring and early warning on the axis of the open caisson. The truss is arranged on the inner side of the open caisson, and the center drill bit and the auxiliary drill bits are used for excavating the inner side of the open caisson and sinking the open caisson section by section until the open caisson reaches a preset elevation. By means of the device, deflection or inclination of the open caisson can be reduced or avoided, the structure is simple, the automation degree is high, and turnover and repeated use can be achieved.
本发明提供一种沉井施工辅助装置及施工方法，其中的装置包括中心轴、桁架、固定在中心轴下方的中心钻头，以及固定在桁架上并分布在中心钻头四周的辅助钻头；其中，在桁架上还设置有轴位预警装置，轴位预警装置用于对沉井的轴线进行实时监控及预警；桁架设置在所示沉井的内侧，中心钻头和辅助钻头用于对沉井的内侧进行开挖，并使沉井逐节下沉，直至到达预设标高位。利用上述发明能够减少或避免沉井歪斜或倾斜，结构简单，自动化程度高，且可周转重复使用。
