Waterproof construction is one of the key technologies in the automatic tunneling construction of suspended segmental shaft,and its construction quality will affect the safety of the construction process and the quality of the shaft.Based on this,combined with the actual construction case,this paper summarizes the waterproof construction technology in the construction process of suspended segmental shaft,and provides targeted waterproof measures for different construction links and parts,which has important guiding significance for the subsequent construction of shafts.
