How to build a chimney with a height of 100 m?

? /kloc-When slip-form construction is adopted for chimney concrete over 0/00 meters, attention should be paid to controlling the center point and verticality to avoid deformation; In addition, the sliding mode speed and concrete quality should be controlled.

The advantage of wooden formwork is that it is flexible to make and assemble, and it is more suitable for concrete members with complex or irregular shapes and concrete projects constructed in winter. Disadvantages are large output and waste of wood resources.

The advantages of composite steel formwork are light and flexible, easy to assemble and disassemble, strong universality and high turnover rate. The disadvantage is that there are many joints and poor sealing, which leads to poor appearance quality of concrete after molding. Lifting-free formwork is suitable for high-rise buildings with shear wall system or simplified system, towering silos, water towers, shafts, TV towers, chimneys, frames and other structures.
