Method for quickly dismantling upper structure of cable-stayed bridge
The invention relates to the technical field of bridge dismantling construction, and particularly relates to a method for quickly dismantling an upper structure of a cable-stayed bridge. The method comprises the following steps of (A) dividing a beam section; (B) determining a size and a buried depth of a steel pipe pile (1); (C) drilling a hole in a proper position of a beam body; (D) sinking thesteel pipe pile to a specified depth; (E) releasing a stay cable and removing the beam section; and (F) hoisting the beam section to a specified position. In the invention, a construction sequence ofdismantling the upper structure of the cable-stayed bridge is optimized; and through temporary supporting of the steel pipe pile (1), a situation that the beam body is likely to laterally overturn inthe dismantling process of the upper structure of the cable-stayed bridge is avoided, the stability of the beam body in the dismantling process is guaranteed, the safety of the construction process is ensured, a construction period is shortened, construction efficiency is improved, construction cost is reduced, and the method can be popularized in actual engineering.
本发明涉及桥梁拆除施工技术领域，具体涉及一种快速拆除斜拉桥上部结构的方法，包括以下步骤：(A)划分梁段；(B)确定钢管桩(1)尺寸及入土深度；(C)梁体适当位置钻孔；(D)钢管桩下沉至指定深度；(E)释放斜拉索并拆除梁段；(F)吊运梁段至指定处。本发明中，优化了斜拉桥上部结构拆除的施工顺序，通过钢管桩(1)临时支撑，避免了斜拉桥上部结构拆除过程中可能出现梁体侧向倾覆的情况，保证了拆除过程中梁体的稳定性，确保了施工过程的安全，缩短了施工工期，提高了施工效率，降低了施工成本，可以在实际工程中推广。
