Construction method for transverse splicing transformation of bridge tower of cable-stayed bridge suitable for concrete bridge tower
The invention discloses a cable-stayed bridge tower transverse splicing reconstruction construction method suitable for a concrete bridge tower, which comprises the following steps of: newly building a first cable-stayed bridge with at least one first bridge tower on one side of an old bridge, and pre-burying a plurality of first prestressed pipelines in the first bridge tower; dismantling the old bridge; at least one second bridge tower is constructed and reconstructed at the bridge site of the old bridge, the second bridge tower is connected with the first bridge tower, and a plurality of second prestressed pipelines connected with the first prestressed pipelines in a one-to-one correspondence mode are pre-buried in the second bridge tower; prestressed steel bars penetrate into the first prestressed pipeline and the second prestressed pipeline, then the two ends of the prestressed steel bars are tensioned, grouting is conducted in the first prestressed pipeline and the second prestressed pipeline after tensioning, and concrete is used for anchor sealing. According to the method, the transverse width of the whole bridge is reduced, the concrete volume of the bridge tower is reduced, and the appearance is lighter, thinner and more attractive.
本发明公开了一种适用于混凝土桥塔的斜拉桥桥塔横向拼接改造的建造方法，包括以下步骤：在旧桥的一侧新建一座具有至少一个第一桥塔的第一斜拉桥，并在第一桥塔中预埋有若干第一预应力管道；拆除旧桥；在旧桥的桥址处施工重建出至少一个第二桥塔，且第二桥塔与第一桥塔相连接，在第二桥塔中预埋有若干与第一预应力管道一一对应连接的第二预应力管道；将预应力钢筋穿入第一预应力管道和第二预应力管道中，而后对预应力钢筋的两端进行张拉，张拉后在第一预应力管道和第二预应力管道中压浆，并用混凝土封锚。本发明方法既减小了桥梁整体的横向宽度，又减小了桥塔的混凝土方量，外形上也更加轻薄、美观。
