Main tower hoisting method of special-shaped space tower curve cable-stayed bridge
The invention relates to the technical field of bridges, and provides a main tower hoisting method of a special-shaped space tower curve cable-stayed bridge, which comprises the following steps: hoisting two base tower sections; a first guide backup plate is installed on the side wall of the top end of each base tower section, and the first guide backup plates protrude out of the top faces of the base tower sections; a first telescopic cross arm is installed at the top ends of the two base tower sections, and the distance between the top ends of the two base tower sections is adjusted through the first telescopic cross arm; a herringbone tower section is hoisted to the positions above the two base tower sections, and the two bottom ends of the herringbone tower section slide to the top ends of the corresponding base tower sections along the corresponding first guide backup plates correspondingly; and the first telescopic cross arms are adjusted, so that the two bottom ends of the herringbone tower section are accurately in butt joint with the top ends of the corresponding base tower sections. Therefore, the installation efficiency and speed of the main tower of the special-shaped space tower curve cable-stayed bridge are improved.
本发明涉及桥梁技术领域，并提供一种异型空间塔曲线斜拉桥的主塔吊装方法，包括：吊装两个基座塔节；在每个所述基座塔节的顶端侧壁安装第一导向靠板，并使所述第一导向靠板突出于所述基座塔节的顶面；在两个所述基座塔节的顶端安装第一伸缩横撑，通过所述第一伸缩横撑调节两个所述基座塔节的顶端之间距离；将人字形塔节吊装到两个所述基座塔节上方，并使所述人字形塔节的两个底端分别沿着对应的所述第一导向靠板滑向对应的所述基座塔节顶端；调节所述第一伸缩横撑，使所述人字形塔节的两个底端与对应的所述基座塔节顶端准确对接。这样提高了异型空间塔曲线斜拉桥主塔的安装效率和速度。
