Bridge lifting device, bridge transformation system and bridge transformation construction method
The invention relates to the technical field of bridge reinforcement, and concretely relates to a bridge lifting device, a bridge transformation system and a bridge transformation construction method.The method comprises the following steps that S1, a to-be-lifted bridge section is lifted through a lifting unit arranged at the lifting ends of two bridge lifting mechanisms and temporarily supported; S2, the two bridge lifting mechanisms are moved to the two sides of the next to-be-lifted bridge section till lifting and temporary supporting of all the bridge sections are completed; S3, two setsof semi-frame bodies are placed on the ground on the two sides of the lifted bridge section, and the lifting device is arranged above the two sets of semi-frame bodies; S4, the lifting device lifts the two sets of semi-frame bodies to the preset height and then moves to the installation position of a construction hanging bracket, and the two sets of semi-frame bodies are arranged on a pier in a sleeving mode after being spliced; and S5, connection between the lifting device and the semi-frame bodies is removed, and step S3 and step S4 are repeated to install the next construction hanging bracket. The problems that in the prior art, a hydraulic jack is adopted for pier heightening, the jacking stroke is limited, a specially-designed steel cushion block needs to be adopted, and the construction efficiency is low can be solved.
本发明涉及桥梁加固技术领域，具体涉及一种桥梁提升装置、改造系统及改造施工方法。该方法包括以下步骤S1：利用设置在两台提梁机构提升端的起吊单元提升待提升的桥梁节段并临时支撑；S2：移动两台提梁机构至下一待提升桥梁节段两侧，直至完成所有桥梁节段的提升和临时支撑；S3：将两组半架体放置在已提升的桥梁节段两侧的地面上，提升装置至两组半架体上方；S4：提升装置吊起两组半架体至设定高度后，移动至施工吊架的安装位置，使两组半架体拼接后套设在桥墩上；S5：解除提升装置与半架体的连接，重复步骤S3‑S4安装下一施工吊架。能够解决现有技术中桥墩接高采用液压千斤顶，顶升行程有限，需采用专门设计的钢垫块，且施工效率低的问题。
