Construction method of prefabricated bridge bearing platform splicing surface pier column embedded bars
The invention discloses a construction method of prefabricated bridge bearing platform splicing surface pier column pre-embedded bars, and relates to the technical field of municipal bridge construction, the construction method comprises the following steps: 1, construction preparation; step 2, supporting the foundation pit; thirdly, a bearing platform foundation pit is excavated, and a foundation pit cushion layer is constructed; fourthly, bearing platform steel bars are welded, and embedded bars are installed; fifthly, a positioning jig frame is supported; sixthly, prefabricated pier column embedded bars are welded to the splicing face of the bearing platform; seventhly, bearing platform formwork installation and concrete pouring are conducted; eighthly, the positioning jig frame and the bearing platform formwork are removed; ninthly, a bearing platform foundation pit is backfilled, and pier column embedded bars are protected; and tenthly, pier columns are installed. By means of the positioning jig frame, accurate positioning and mounting of the bridge lower structure prefabricated pier column embedded bars are achieved, the position accuracy and the spacing qualification rate of the embedded bars are improved, the construction progress is accelerated, the cost input is reduced, machining is convenient and fast, and practicability is high.
本发明公开了一种装配式桥梁承台拼接面墩柱预埋筋的施工方法，涉及市政桥梁施工技术领域，包括如下步骤：步骤一、施工准备；步骤二、基坑支护；步骤三、承台基坑开挖及基坑垫层施工；步骤四、承台钢筋焊接及预埋筋安装；步骤五、定位胎架支设；步骤六、承台拼接面焊接预制墩柱预埋筋；步骤七、承台模板安装及混凝土浇筑；步骤八、定位胎架及承台模板拆除；步骤九、承台基坑回填及墩柱预埋筋保护；步骤十、安装墩柱。本发明通过定位胎架实现了桥梁下部结构预制墩柱预埋筋的精确定位安装，提高了预埋筋位置的精准度及间距合格率，加快了施工进度，降低了成本投入，加工便捷、实用性强。
