The invention discloses an ultra-large-diameter shield tunnel freezing drilling liftable hanging basket type construction platform which comprises a freezing construction operation platform, an upper lifting operation platform, a hanging basket lifting platform and a box culvert internal lifting platform. The other end of the freezing construction operation platform is connected with a tunnel segment located on one side of a connection channel, and the upper lifting operation platform is installed on the top of the freezing construction operation platform. According to the box culvert drilling device, horizontal and vertical angles of drilling of the upper portion and the lower portion of a box culvert can be accurately adjusted through the lifting platform, and accurate drilling is achieved; a hanging basket lifting platform is adopted for a middle hole position of the platform, and the middle hole position of the platform is drilled at any angle by moving the lifting platform up and down; a drilling machine is arranged in the box culvert through a lifting platform in the box culvert at the lower hole position of the box culvert, small holes are formed in the corresponding box culvert, and accurate drilling is achieved.
本发明公开一种超大直径盾构隧道冻结钻孔可升降吊篮式施工平台,包括冻结施工作业平台、上部升降作业平台、吊篮升降平台和箱涵内部升降平台,所述冻结施工作业平台的一端连接在箱涵上,所述冻结施工作业平台的另一端和位于联络通道一侧的隧道管片相连,所述上部升降作业平台安装在所述冻结施工作业平台的顶部上。本发明,箱涵上部、下部钻孔通过升降平台可以精准调整钻孔水平和垂直角度,实现精准钻孔;平台中部孔位采用吊篮升降平台,通过升降平台进行上下移动,对平台中部孔位实现任意角度钻孔;箱涵下部孔位通过箱涵内部升降平台,将钻机布置在箱涵内部,在对应箱涵上开小孔,实现精准钻孔。
