Multi-point continuous incremental launching construction method for steel box girder
The invention provides a multi-point continuous incremental launching construction method for a steel box girder. The multi-point continuous incremental launching construction method comprises the steps that S1, temporary piers are erected; s2, an assembling platform is erected; s3, pushing equipment and a vertical jack are installed; s4, assembling the steel box girder; s5, pushing the steel box girder; s6, repeating the step S5; and S7, falling a beam. By adopting separated pushing of the pushing equipment and the vertical jack, the stress is definite, the structure is simple, the beam falling height is reduced, and the overall stability in the construction process is ensured; the difficulties that the bridge site is a river channel, a Chuan valley, a complex terrain and the like are overcome, and particularly in an area with high requirements on environmental protection and water system protection, the superiority can be better shown by adopting'different-position splicing and integral pushing 'construction; the construction temporary occupied area can be effectively reduced, the local environment is protected, construction organization is facilitated, the construction period is shortened, and the construction cost can be greatly reduced.
本发明提供一种钢箱梁多点连续顶推施工方法，该方法包括：S1、搭设临时墩；S2、搭设拼装平台；S3、安装顶推设备和竖向千斤顶；S4、拼装钢箱梁；S5、顶推钢箱梁；S6、重复步骤S5；S7、落粱。通过采用顶推设备和竖向千斤顶的分离式顶推，受力明确，结构简单，降低了落梁高度，保证施工过程中，整体的稳定性；克服了桥位处为河道、川谷，地形复杂等困难，特别是在对环境保护、水系保护要求高的区域，采用“异位拼装，整体顶推”施工更能显示出其优越性；可有效减少施工临时占地，保护当地环境，并有利于施工组织，缩短工期，能够较大幅度的降低施工成本。
