Synchronous installation method for prestressed steel bundles and prefabricated pier segments
The invention relates to a synchronous installation method for prestressed steel bundles and prefabricated bridge pier segments, and relates to the technical field of bridge engineering construction, and the synchronous installation method comprises the following steps: S1, when a bridge pier foundation of a bridge is poured, one end of a steel strand bundle is fixed in the bridge pier foundation; S2, the prefabricated pier section is hoisted to the position above the pier foundation, and a certain distance is reserved between the bottom face of the prefabricated pier section and the pier foundation; S3, a traction rope is made to penetrate from top to bottom from the prestressed duct, and connecting and fixing the other end of the steel strand bundle; S4, the prefabricated bridge pier section is moved, and the steel strand bundle penetrates into a prestressed duct of the prefabricated bridge pier section; and S5, after the steel strand bundle completely penetrates through the prestressed hole channel and is in a vertical state, the prefabricated pier section is slowly lowered till the bottom face of the prefabricated pier section is attached to the top face of the pier foundation; the flexible steel strand bundle is adopted as the prestressed steel bundle, the prefabricated bridge pier sections are installed while the steel strand bundle penetrating is completed, and the anchoring work of the steel strand bundle is simple, convenient and fast.
本申请涉及一种预应力钢束与预制桥墩节段同步安装方法，涉及桥梁工程施工技术领域，包含步骤：S1：在浇筑桥梁的桥墩基础时，将钢绞线束的一端固定在桥墩基础内；S2：将预制桥墩节段吊运至桥墩基础上方，且预制桥墩节段底面距离桥墩基础留有一段距离；S3：将牵引绳从预应力孔道从上至下穿入，并连接固定钢绞线束的另一端；S4：移动预制桥墩节段，钢绞线束穿入预制桥墩节段的预应力孔道；S5：待钢绞线束完全穿过预应力孔道，并呈竖直状态，缓慢下放预制桥墩节段至其底面贴合桥墩基础的顶面；本申请采用柔性的钢绞线束作为预应力钢束，在完成钢绞线束穿束的同时，进行预制桥墩节段的安装，且钢绞线束的锚固工作简单便捷。
