Jinyidong project of China railway no.2 engineering group no.3 company realized the first frame of prefabricated box girder

This newspaper yiwu (correspondent jinshan ZhaiFei sails) on December 30, 10 o 'clock in the morning, and in iron 2 bureaus three companies Jin Yi east regional rail transit engineering construction standard GH13 # 13 - GH14 # pier between, 29.94 m long, 1.8 m high and weighs 430 tons of precast beam, lasted 66 minutes were firmly on the pier, precast concrete box girders of the first cross project successfully completed all of the erection work.

In order to ensure the successful erection of the first truss box girder, the project department made strict scientific preparations for the first truss from the field and technical aspects. The prefabricated beam field applies the standardized management concept, adopts the factory management mode, utilizes the intelligent mechanical equipment, guarantees the prefabricated simply supported beam 100% high quality; According to the structural characteristics of box girder, organize technical team meeting for many times, using BIM technology to the prefabricated field planning, template design, choice of machinery, steel processing and binding, concrete pouring, tension and grouting, concrete curing, girder and beam transport, construction and so on various aspects to carry on the strict scientific and standardized, and formulates the bid for this special construction scheme, construction scheme and safety ensure that technology is absolutely feasible; At the same time, the project organized the first frame deployment meeting for many times, invited experts from the group company to review the frame production and transportation plan, and made detailed deployment of each process to ensure 100% safety of the erection.

The successful erection of the first prefabricated simply supported box girder marks the beginning of the construction phase of the bridge superstructure for the civil engineering project of jinyidong city.
