Arch Culvert Steel Formwork

Working Principle of Tunnel Lining Trolley

The role of the gantry system is to support the entire Formwork System and prevent the formwork from deforming and shrinking inwardly under pressure when lining the lining. The mast mainly consists of upper and lower longitudinal beams, columns, mast beams, longitudinal joints, reinforced diagonal braces, formwork beams, formwork columns, screw rods, cylinders, transversal mechanisms, walking mechanisms and other components. Among them, the gantry beam is an important load-bearing component of the Formwork Trolley, which requires high material strength and rigidity. Generally, the section is made of tailor-welded H-shaped steel, industrial steel, etc. For variable-section tunnels, the formwork must be moved to the outside, and the portal beam must be lengthened. When designing, you can add a widening block on one side, and move the lateral movement mechanism to the side of the widening block; or design it into two left and right blocks, add a widening block in the middle part, and the lateral movement mechanism will move with the two blocks. mobile.

product feature:

* It is widely be used in all kinds of tunnel concrete construction
* The product is easy to use and flexible to disassemble.
* More times turnover, low cost amortization.
* The appearance of concrete is well quality.
* Save labor cost and reduce project cost.

Advantage:

● light weight; 
● simple, strong and stable structure; 
● moved, mounted and stripped easily; 
● strong reusability; 
● small deformation under force; 
● adequate space under traveler and providing a big space for bars and formwork construction operation.
