港珠澳大桥每座预制桥墩的承台内预留6个带甩筋的后浇孔，桥墩安装完成后要对预留钢筋进行接驳，并且施加预紧力。在承台预制时，通过内芯模对甩筋进行精确定位，保证对接钢筋具有较高的同心度，使后浇孔内的钢筋实现顺利对接，满足结构受力要求。
港珠澳大橋每座預製橋墩的承檯內預留6箇帶甩觔的後澆孔，橋墩安裝完成後要對預留鋼觔進行接駁，併且施加預緊力。在承檯預製時，通過內芯模對甩觔進行精確定位，保證對接鋼觔具有較高的同心度，使後澆孔內的鋼觔實現順利對接，滿足結構受力要求。

There are six pouring holes with extended rebar set aside within each cap of prefabricated bridge pier of the Hongkong-Zhuhai-Macao Bridge. We need to put the rebar butt after the installation of the bridge pier, then apply pre-tighten-ing force. Extended rebar is positioned accurately by internal formwork to ensure that docking rebar has good concentricity when the cap is prefabricated, and rebar in the pouring hole is docked smoothly, to make structure meet the requirements of stress.
