Construction method for installing steel box lifting basket arch bridge arch rib in movable lifting point mode
The invention discloses a construction method for installing a steel box lifting basket arch bridge arch rib in a movable lifting point mode, and belongs to the technical field of arch bridge arch rib installation. The construction method comprises the following steps that S1, the hoisting length of a hoisting rope at each hoisting assembly is calculated according to the inward inclination angle of the arch rib; s2, a lifting rope is connected to the lifting assembly, and then the arch rib is lifted in a mode of contracting the lifting rope; s3, the arch rib is hoisted to the outer side of the arch rib mounting area through a sports car; s4, adjusting the distance between the arch rib and the middle line of the bridge by moving the frame; s5, the mounting precision of the ends of the arch ribs is finely adjusted through the hoisting assemblies; and S6, the arch ribs and the assembled part of the bridge body are spliced and installed. According to the technical scheme, the problems that in the prior art, an arch rib lifting device is difficult to accurately and finely adjust the aerial posture of an arch rib, so that the installation difficulty of the arch rib is increased, and the installation efficiency is reduced are solved.
本发明公开了一种吊点活动式安装钢箱提篮拱桥拱肋的施工方法，属于拱桥拱肋安装技术领域。该施工方法包括如下步骤：S1、根据拱肋内倾角度计算出各个吊装组件处吊绳的吊装长度；S2、将吊绳连接于吊装组件上，然后通过收缩起重索的方式将拱肋提升；S3、通过跑车将拱肋吊装至拱肋安装区域的外侧；S4、通过移动框架调整拱肋与桥中线的间距；S5、通过吊装组件对拱肋端部的安装精度进行微调；S6、将拱肋和已组装部分的桥体进行拼接安装。本技术方案用以解决现有技术中对拱肋的起吊装置，难以对拱肋的空中姿态进行精准的微调，导致拱肋的安装难度加大，安装效率降低的问题。
