【 摘 要 】

After years of development and exploration of bridge construction technology, new construction methods have emerged. Relevant researchers continue to deepen the research and exploration of mobile formwork. The application of this method to bridge construction has only been developed in recent years. Because of this bridge construction method has many advantages, it is selected in modern bridge construction. The scope of application is more and more extensive. The construction method of the movable formwork construction method is procedural, which can greatly reduce the construction period, it has a relatively small impact on normal traffic, does not require a large amount of basic treatment work before the construction and can make the construction period to a large extent. shorten. These advantages make the construction method of mobile formwork developed and applied relatively quickly, especially in the construction of medium and small span bridges, the advantages of its application are more obvious. In the construction of large-scale bridges, large-scale movable formworks are needed. There are still many problems that need to be solved in the construction of large-scale movable formworks for construction bridges, such as crack control, faulty stage control, and construction safety guarantee. In the study of this paper, the application technology of mobile formwork in bridge construction was discussed from aspects of construction design, construction control, etc., through the moving formwork structure. In terms of force analysis, load, etc., the key technologies for control of construction box girders are studied. From the aspects of abutment structure processing, pre-compression of movable formwork and intermediate-outside formwork adjustment, the key construction technology of "one-mold double beam" movable formwork was studied. The passage provides practical reference for relevant technical personnel of bridge construction and provide method cases for researchers in the field of mobile formwork construction control technology.
