Fabricated concrete pier with steel pipe-in-pipe prestressed steel cable connection and construction method of fabricated concrete pier
The invention belongs to the technical field of bridge engineering, and particularly relates to a steel pipe-in-pipe prestressed steel cable connected fabricated concrete pier and a construction method thereof. The prefabricated segment units are arranged on the cast-in-place bearing platform unit, the cast-in-place segment units are arranged between the adjacent prefabricated segment units, and the in-pipe concrete steel beam units are arranged on the whole of all the prefabricated segment units, so that it is guaranteed that the structural integrity of the fabricated concrete pier is higher, the connection strength is higher, and the construction period is shortened. And the supporting stability is better. In addition, the invention further provides a construction method of the fabricated concrete pier, which sequentially comprises the following steps of: casting and forming the prefabricated segment units in a factory, mounting the in-pipe concrete steel beam units, casting to obtain the cast-in-place bearing platform units, casting to obtain the cast-in-place segment units, tensioning, anchoring and casting the in-pipe concrete steel beam units. And the orderly and efficient construction effect of the fabricated concrete pier is ensured.
本发明属于桥梁工程技术领域，尤其涉及一种钢管‑管内预应力钢束连接的装配式混凝土桥墩及其施工方法。本发明通过在现浇承台单元上设置若干个预制节段单元，并在相邻预制节段单元之间设置现浇节段单元、在所有预制节段单元的整体上设置管内混凝土钢束单元的方式，保证该装配式混凝土桥墩的结构整体性更高，连接强度更大，支撑稳定性更好。此外，本发明还提供一种上述装配式混凝土桥墩的施工方法，其依次包括以下步骤：工厂内浇筑成型预制节段单元、安装管内混凝土钢束单元、浇筑得到现浇承台单元、浇筑得到现浇节段单元，以及张拉、锚固、浇筑管内混凝土钢束单元，保证该装配式混凝土桥墩的有序、高效施工效果。
