1, turnover formwork construction method is suitable for solid or thin-walled piers with equal or variable cross-section, with wide application range and good appearance quality. The disadvantage is that tower cranes are frequently used and need more support and auxiliary equipment.

2. Slipform construction method is an active continuous forming construction technology with high mechanization in cast-in-place concrete structure construction, which has the advantages of strong construction integrity and fast construction speed. However, due to the high requirement for continuity in slipform construction, the construction workers are tired and unpredictable.

3. The climbing formwork construction method is suitable for pier columns, cable tower columns, etc. , a wide range. Advantages are good physical and appearance quality, closed construction environment, smooth and safe construction, low labor intensity of workers, and disadvantages are large investment and slow construction progress. Therefore, the construction methods of these three high piers are different.
