According to the construction practice of entire jacking of Chengdu Hongpailou interchange approach bridge, feasibility study on alternating jacking construction scheme is performed, the key technical points of jacking construction process are introduced such as entire jacking technology, bracket system, limiting location system and the formal lifting technology. The entire jacking construction of bridge strengthening is fulfilled smoothly. Engineering practice shows that alternating lifting construction can eliminate the emergence security risks due to the jack lifting failures, ensure the entire lifting process safe and reliable.
