If conventional template and concrete pouring method is used for tall cylindrical buildings, then the structure can be built to great height, but air holes easily generate due to large height difference causing concrete to shake
Solution Approach 1:
The construction process is segmented into multiple pouring stages, with the template divided into sections that can be poured sequentially from bottom to top. The lifting platform enables the pouring system to work in sections rather than requiring complete pouring from maximum height simultaneously, reducing the effective height difference at any given time.
Solution Approach 2:
The lifting platform provides dynamic adjustment capability, allowing the pouring system to move vertically along the guiding rail frames. This enables continuous adaptation to different pouring heights and maintains optimal pouring conditions throughout the construction process, preventing concrete shaking caused by excessive height differences.
2Manufacturing precision
If multiple vibrations are performed in later stage to eliminate air holes, then concrete quality can be improved, but it requires multiple workers and vibration devices which is time-consuming and labor-intensive
Solution Approach 1:
Vibration is performed preliminarily during the concrete pouring process itself rather than in later stages. The tamping device vibrates concrete in real-time as it is being poured, eliminating air holes before the concrete sets. This preliminary action prevents the need for multiple subsequent vibration operations.
Solution Approach 2:
The pouring and vibration operations are merged into a single integrated process. The tamping device is combined with the pouring system on the lifting platform, allowing simultaneous pouring and vibration in one coordinated operation rather than separate sequential operations requiring multiple workers and devices.
3Manufacturing precision
If manual vibration work is performed by multiple workers at multiple places, then air holes can be eliminated, but the process is labor-intensive with low construction efficiency
Solution Approach 1:
The system performs vibration automatically through the integrated tamping device without requiring manual intervention by multiple workers. The mechanical vibration system serves the concrete itself directly at the pouring location, eliminating the need for human workers to manually operate vibration devices at multiple positions.
Solution Approach 2:
Manual vibration work by workers is replaced with an automated mechanical vibration system. The tamping device provides consistent, controlled vibration through mechanical means rather than manual operation, reducing labor requirements and construction time while maintaining concrete quality.
