Swivel bridge interfered pier jacking system and rapid construction method
The invention discloses a swivel bridge interfered pier jacking system and a rapid construction method, the swivel bridge interfered pier jacking system comprises a main beam and an interfered pier, an interfered pier foundation is arranged below the interfered pier, and a swivel section of the main beam is arranged at the top of the interfered pier; a capping beam is arranged on the top of the interfered pier, and a jacking system is arranged in the middle of the interfered pier. The construction method comprises the following steps: 1) constructing the foundation and the prefabricated part; 2) rotating and jacking; (3) a support is installed, and a post-pouring section is constructed; and (4) the jacking system is dismantled, and a bridge is formed. Compared with the prior art, the method has the advantages that due to the existence of the jacking process, before rotation, the bent cap of the interfered pier is located at the low position, and support erection, beam body prefabrication and rotation construction are basically not affected; influence on existing line operation is small, time for occupying railway skylights is short, safety and reliability are achieved, and application is wide; the construction period is short, and the turnover efficiency of materials and machines such as a jacking system is improved; the main beam is prevented from being in a cantilever state for a long time, and structure and construction safety is improved.
本发明公开了一种转体桥梁被干扰墩顶升系统及快速施工方法，包括主梁和被干扰墩，被干扰墩下方设有被干扰墩基础，主梁的转体段设置在被干扰墩顶部；被干扰墩顶部设有盖梁，被干扰墩中部设有顶升系统。施工方法包括：1)施工基础及预制部分；2)转体、顶升；3)支座安装、后浇段施工；4)拆除顶升系统、成桥。本发明与现有技术相比的优点在于：由于顶升过程的存在，在转体前，被干扰墩的盖梁处于低位，基本不影响支架搭设、梁体预制及转体施工；对既有线路运营影响小，占用铁路天窗时间少、安全可靠，应用广泛；施工工期短，增加顶升系统等材料和机械的周转效率；避免主梁长期处于悬臂状态，提高结构和施工的安全性。
