Limited space pier group hollow high pier asynchronous hydraulic creeping formwork construction method
The invention discloses a limited space pier group hollow high pier asynchronous hydraulic creeping formwork construction method which comprises the steps that a left front pier column, a left rear pier column, a right front pier column and a right rear pier column are built through a hydraulic creeping formwork system, and the left front pier column, the left rear pier column, the right front pier column and the right rear pier column form double-limb thin-wall hollow piers through inter-pier tie beams respectively; each pier column is divided into 24 sections and a pier top stop block for construction; firstly, a tower crane is installed in front of the middle of a left front pier column and a right front pier column, then the left front pier column is constructed, after the first section and the second section of the left front pier column are constructed, the right front pier column starts to be constructed, and after the first section and the second section of the right front piercolumn are constructed, a right rear pier column starts to be constructed; after the first section and the second section of the right rear pier column are constructed, the left rear pier column starts to be constructed; and after construction of the four pier columns is completed and the creeping formwork system is dismounted, construction of tie beams between the piers is conducted. The jackinginterference of the hydraulic climbing formwork system in different construction procedures can be avoided in a limited space.
本发明公开了一种有限空间桥墩群空心高墩异步液压爬模施工方法，采用液压爬模系统筑造左幅前、后墩柱和右幅前、右幅后墩柱，左幅前、后墩柱及右幅前、后墩柱各自通过一根墩间系梁构成双肢薄壁空心墩；每座墩柱均分成24个节段和一个墩顶挡块进行施工；先在左幅前墩柱和右幅前墩柱的中间前方安装塔吊，接着施工左幅前墩柱，在施工完成左幅前墩柱的第1和第2节段后，开始施工右幅前墩柱，在施工完成右幅前墩柱的第1和第2节段后，开始施工右幅后墩柱，在施工完成右幅后墩柱的第1和第2节段后，开始施工左幅后墩柱；在四座墩柱施工完成并拆除爬模系统后，进行墩间系梁施工。本发明能在有限的空间内，避免不同施工工序液压爬模系统顶升的干扰。
