Construction of a bridge over the Aksu Chai River,Mugandli village, Azerbaijan (permanent cross-section supports)
SELF-LIFTING HYDRAULIC FORMWORK, FOR THE CONSTRUCTION OF A SUPPORT SECTION WITH A PERMANENT THE SECTION IS 3 METERS HIGH
FEATURES OF SELF-CLIMBING FORMWORK FOR CONSTRUCTING CONSTANT CROSS-SECTION PIERS:
- Adaptation to the structure's geometry: The self-climbing formwork precisely follows the pier's cross-section along its entire height, ensuring high accuracy in shaping and minimizing deviations from the design dimensions
- High Safety Standards: The lifting mechanisms are equipped with locking systems that prevent uncontrolled movements and accidental falls
- Automated movement: The formwork is lifted using hydraulic jacks without the need for cranes or additional lifting equipment, optimizing construction logistics
- Capability for construction work at great heights (over 100–150 m)
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

MY ROLE AT THIS SITE
My role in this project involved the design, manufacturing, installation,
and training of personnel in the operation of a specialized self-climbing
formwork system for concreting bridge piers with a constant crosssection throughout their height. The pier dimensions are 8.2 × 3.5 m
Bridge piers No. 7 and No. 8 before the installation of the self-climbing hydraulic formwork
Up to a height of 27–30 m, climbing formwork was used, while the remaining sections (up to 58–60 m) will be concreted with the self climbing hydraulic formwork
Installation of a transition element on a 100-ton horizontal jack
The jacks secure the formwork to the bridge pier and are equipped with a safety nut for reliability
Pre-assembly of the first and second tiers at
the factory includes full installation of all
elements and placement of 100-ton horizontal
hydraulic jacks into designated slots
Pre-assembly of the third tier, consisting of two
C-shaped halves and connecting elements,
including 100-ton horizontal hydraulic jacks
