The Cantilever Form Traveller consists of a large steel framework that is supported by a set of temporary supports or towers. It is typically positioned at one end of the bridge or viaduct and gradually extends outwards as the construction progresses.
1. Initial Positioning: The Cantilever Form Traveller is initially positioned at the starting point of the bridge or viaduct, often on one of the piers or abutments.
2. Segment Placement: The first segment of the bridge or deck section is placed on the Cantilever Form Traveller. This segment is typically precast or cast in situ.
3. Balanced Construction: The Cantilever Form Traveller uses its temporary supports or towers to balance the weight of the segment being placed. This ensures that the structure remains stable during construction.
4. Incremental Extension: Once the first segment is in place, the Cantilever Form Traveller gradually extends outward by pushing or pulling itself along the completed segments. This allows for the placement of subsequent segments.
5. Repetition: The process of segment placement, balanced construction, and incremental extension is repeated until the entire bridge or viaduct is constructed.
The Cantilever Form Traveller offers several advantages in bridge construction, such as increased efficiency, reduced labor requirements, and improved safety. It allows for the construction of long-span bridges and viaducts without the need for temporary supports in the water or deep foundations.
It's important to note that different variations of Cantilever Form Traveller exist, and their specific mechanisms may vary. However, the general principle remains the same – supporting balanced construction and incremental extension during bridge or viaduct construction.
What are the advantages of using a Cantilever Form Traveller?
A cantilever form traveller is a type of constructed travel form equipment used in the construction of bridge decks and other large concrete structures. It is a self-contained system that can be used to construct large sections of concrete in a controlled and efficient manner. There are several advantages to using a cantilever form traveller.
First, bridge traveller allows for the construction of large sections of concrete in a single pour. This means that there are fewer joints in the finished structure, which can improve its overall strength and durability.
Second, a cantilever form traveller is a highly efficient construction method. It allows for the rapid construction of large sections of concrete, which can save time and money compared to traditional construction methods.
Third, form traveller system bridge construction is a safe construction method. The equipment is designed to be self-supporting, which means that workers do not need to be exposed to the hazards of working at heights or on unstable scaffolding.
Overall, a cantilever form traveller is a highly effective construction method that can be used to build large form traveller bridge construction quickly, safely, and efficiently.
