To improve the
efficiency and safety of vertical shaft construction, a vertical shaft sinking
mahine (VSM) is adopted. A case study is conducted on the caissontype
parking facility construction project (Phase 1) in Jianye district, Nanjing,
China, and the design concept of prefabricated shaft concrete segment structure
for shaft is systematically introduced, including structure detail and size,
segment joint, mechanical analysis, and waterproof design. Then, the segment
structure is optimized and the design concept of the universal segment is first
proposed in the VSM project. The whole ring is devided into six equal segments
to improve the efficiency and quality of construction significantly. The field
application results show that the circular shat segment has a good stress state
with good waterproofing capacity.
