With the rapid development of the national economy , China 's highway construction has made great achievements . Has completed the planning of the national highway network , and how to achieve these highway network formed at the same time , new roads , with the title of the original highway , is an important topic in the current highway construction . The bridge construction is a key link for the bridge construction , bridge construction technology level direct influence on the development of the bridge construction , the construction method is an important part of the construction process , and runs through the bridge construction . Therefore , the bridge construction methods has been an important bridge engineering research . Pushing construction method has the necessary equipment , occupy the venue and small , narrow venue at the bridge site , construction poor transport conditions , has a broad application prospects . Has both economic and fast , convenient and simple construction , quality assurance features . In this paper, the Beijing-Zhuhai Expressway and Xing Wei Express easy Voeux Road located topography, geology and other natural conditions and engineering characteristics of the wear overloaded expressway box bridge under construction by incremental launching method for the study of object pushing construction of bridges control technology to carry out a systematic study to guarantee the opening of the Beijing-Zhuhai Expressway , affordable , convenient , and conservation of an area of ??the purpose . To securely and successfully completed the construction tasks to ensure the quality of construction , and achieved good social and economic benefits .
