Introduction
The Form traveler is the main equipment in the cantilever construction method, According to the structural form can be divided into trussed type(as diamond, triangle), Cable-stayed type, cable-stayed type and mixed type.We are generally used the formtraveler cantilever construction plan when the bridge crossing the mountain valley, river channel and vehicle or ships impassable.
Our company has eight patents in the formtraveler design, production and construction and our formtraveler which have 3 times technological innovation since was produced by our Company:
BY-I Group bolts structure of Formtraveler
BY-II Pin-jointed structure of Formtraveler
BY-III Pin-jointed with hydraulic driving systems of Formtraveler
Specifications
traveler form
1 Material: Q235 or Q345
2 Firm and stable, little deformation
3 Cast-in-place
Traveler Form
There are 4 types of form traveler: truss type (including horizontal chord with no counterweight, rhombus, triangular, bowstring, etc.), cable-stayed (including triangular and pre-stressed), profiled steel and hybrid according to form of structure.
The rhombic form traveler designed and manufactured by Sanbo consists of main trusses, hanging system, anchoring system, travelling system and bottom formwork. Constructors placing 2-4 meters each time, and after the bridge is hardened and reaches adequate strength, hydraulic equipment will push the form travelers forwardly, then a new section of bridge is casted.
Construction process of cast -in-place cantilever method
Form travelers installation-Prestressing bottom panel & outer panel adjusting-fixing bottom panel-vertical prestressed reinforcement & piping installation- inner form & bulkhead panel installation-top rebars colligation/ lashing-top prestressed piping installation-concrete casting- curing - Steel strand inserting - stressing work - concrete grout pressing - Formwork traveler moving- forwarding to next segment.
