In recent years, as the rapid development of infrastructure construction in domestic railway and highway transportation in accordance with the full frame scaffolding construction design of the bridge is also more and more, greatly promote the application of full frame scaffolding process, full frame scaffolding construction technology to improve continuously.

Modern also full frame scaffolding construction technology development in the direction of large tonnage, long-span, regular full frame scaffolding steel bar itself bearing capacity is limited, so to explore how to implement in large tonnage box girder, special working condition of high pier and large cross-section cast-in-situ box girder under the condition of cast-in-place box girder construction is one of the bridge builders often consider problem.

Full frame scaffolding is set in a league or multi span bridge bracket, system changes little, or no, the south approach of the 3^rd bridge according to by hole cast-in-place design, full frame scaffolding construction needs to happen system transformation, but the hole cast-in-place construction method has the advantage that need less number of stents, turns, and use of high efficiency can lead to rob for propping and templates as construction speed is fast.

In China's southern region, water network developed, the proportion of highway Bridges, if uses the conventional full frame scaffolding construction, the need for a large area of soft soil foundation treatment.

Mobile formwork by hole cast-in-place construction joints are usually set in a quarter of span - 1/6 place, is close to the continuous beam near zero moment, construction status and into the bridge state model close to.

Full frame scaffolding is suitable for the height less than 20 m or so of the upper structure, and other construction methods used under the condition of economic construction of bridge superstructure, with turns, turnaround time is short, less use of auxiliary equipment, reducing the waste of human material especially suitable for multi span beam construction.
