Abstract:Based on the unbounded characteristic of PTFE plate, a kind of non-adhesive sliding mode construction technology was proposed. Through the comparative test of slip lift under different concrete strength conditions, the technological performance of the proposed construction technology was explored. The results show that: the proposed construction technology reduces the bonding force between the face slab and the concrete, eliminates the formwork mucous membrane phenomenon caused by the inaccurate control of the concrete strength during the traditional slipform construction, solves the influence of soft demolding sliding on the disturbance of pier concrete in the traditional slipform construction, and can guarantee the quality of pier well.
