Construction method of overpass passage upper structure prefabricated section
The invention provides a construction method of a overpass passage upper structure prefabricated section, which is characterized in that a bridge floor is constructed in blocks, a prefabricated bridgefloor structure is partially adopted, a cast-in-place bridge floor structure is partially adopted, and the construction method comprises the following steps of: measuring, setting out and positioningthe mounting position of an overpass upright post; hoisting the overpass upright post to an installation position for paying off and positioning the overpass upright post, and constructing a bent cap; erecting a scaffold, and carrying out concrete pouring operation in the overpass upright post; hoisting a prefabricated bridge deck to a mounting position on the overpass upright post, and reservingand constructing an expansion joint of the prefabricated bridge deck; binding and supporting the prefabricated bridge deck and a retaining wall, and performing concrete pouring operation on the cast-in-place bridge deck and the retaining wall; maintaining concrete poured on the cast-in-place bridge deck and the retaining wall, constructing a waterproof layer on the top of the cast-in-place bridgedeck, and laying an asphalt pavement. According to the method, the construction principles of segmental and partitioned hoisting and integral unloading in different sections and different areas are adopted.
本发明提供了一种高架桥通道上部结构预制段的施工方法，桥面分块进行施工，部分采用预制桥面结构，部分采用现浇桥面结构，该施工方法包括：对高架桥立柱的安装位置进行测量放线定位；对高架桥立柱进行吊装并吊装至其放线定位的安装位置，并进行盖梁的施工；搭设脚手架，并对高架桥立柱内进行砼浇筑作业；将预制桥面进行吊装以吊装至所述高架桥立柱上的安装位置，并对预制桥面进行伸缩缝的预留和施工；将预制桥面和挡墙进行绑扎和支护，并对现浇桥面以及挡墙进行砼浇筑作业；对现浇桥面以及挡墙浇筑的混凝土进行养护，在现浇桥面的顶部进行防水层的施工并进行沥青路面的铺设。本发明采用分段分块吊装，分联分区整体卸载施工原则。
