The non navigable bridge of the Hongkong-Zhuhai-Macao Bridge east island is a cast-in-situ prestressed concrete box girder, a total of two joints. The second joint was first constructed, adopted twice layered casting construction technology. The technology had been summarized and optimized after the second joint construction finished. Then the first joint adopted the full-section once concreting construction technology, which has optimized the construction technologies of formwork and concrete, and has made big progress in the finished product quality and schedule cost.
