The lifting process of the self-climbing hydraulic formwork for concreting the next 4-meter-high variable-section pier segment
FEATURES OF SELF-CLIMBING FORMWORK FOR VARIABLE-SECTION BRIDGE PIERS
Adaptability to Changing Geometry:
The self-climbing formwork precisely follows the variable
cross-section of the pier, ensuring high geometric accuracy and minimizing deviations from design specifications
High Safety Standards:
The lifting mechanisms are equipped with locking systems
that prevent uncontrolled movements and accidental falls
Cost Reduction for Temporary Structures and Equipment:
Eliminating the need for
extensive scaffolding and temporary supports significantly reduces material costs
Accelerated Construction Process:
Unlike traditional formwork systems, self-climbing formwork
does not require dismantling and reassembly, reducing the overall construction cycle time
Automated Movement
Company Achievements in Using Self-Climbing Formwork for Bridge Pier Construction (First-Time Application of This Technology by the Company):
- Ensuring safe and high-quality construction of bridge piers with a constant cross-section at great heights
- Significant cost reduction through in-house design and manufacturing of sliding hydraulic formwork
- Improving the technological level in the construction of bridge structures
- Strengthening expert competencies in the field of monolithic concreting of complex engineering structures
FEATURES OF THE CANTILEVER CONCRETING METHOD
My role in this project included the design, manufacturing, installation, and training of personnel for the operation of a special self-climbing formwork for a structure with a variable cross-section.
The initial dimensions of the structure at the base are 14 × 8 m, with an internal opening measuring 6.3 × 3 m. As the structure is erected, its external dimensions gradually decrease from 14 × 8 m to 8 × 4 m, while the dimensions of the internal opening remain constant throughout the entire height.
The manufacturing process of rails and special lifting mechanisms for hydraulic formwork
Pre-assembly of external shields at the factory. The shields are sliding, adjustable from 8 to 4 m and fixed by special mechanisms through safety nuts. Simple and reliable design ensures quick fixation of the design position
