The application of full space supports in construction of cast-in-place box beam;

The application of the prestressed steel movable support in the construction of the cast-in-place box beam and its checking computations;

The new construction method of using pre-stressed trusses as formwork for the construction of cast-in-place box girders of tall-pier and big-span bridges is presented in the paper, in which case the truss will be strengthened with arm-ties and connecting bars, and pre-stressed, which will markedly improve its strength and rigidity.

Bearing carrier for cast-in-place box girder of Zhongzhou bridge,adopt steel tube beret beam column structure.

For mobile mould frameworks through a bridge,the cast-in-place box girder construction process is line production,and operational cycle time of every girder is about 15 days.

Taking an example of speeding up the prestressed cast-in-place construction engineering,the article adopts the methods of installing steel wires in the bridge of process of the prestressed cast-in-place box girder to ensure the efficiency of construction,and summarizes the technique and experience of installing steel wires in the box girder,providing the reference for the similar engineering.
