Construction method for erecting segmental beam
The invention relates to a construction method for erecting a segmental beam, which comprises the following steps of: 1, mounting a support on the top of a pier for mounting a span beam section, and adjusting the pre-deviation according to the design; 2, transporting the No.14 beam section to the tail part of the bridge girder erection machine by a beam transporting vehicle; thirdly, feeding beams at the tail and rotating the beams on a bridge girder erection machine; fourthly, the No.14 beam section is moved in the pier direction, and a space for coating epoxy resin is reserved; 5, hoisting the 13 # beam section to the 1 # beam section in sequence; sixthly, epoxy resin is smeared and closely attached, and the prestressing tendons are tensioned; and 7, the suspender is loosened, the beam falls to the designed position, and construction of the next span frame is carried out. According to the method, the problem of erection of the segmental beam without the under-beam beam transporting condition is solved by transporting the beam on the beam, the rapid construction requirement of the segmental beam is met, the problem that a temporary ground shortcut is not arranged across rivers, ecological protection areas and important infrastructures is solved, the cost caused by a steel trestle shortcut needed by a ground route and ground hardening is reduced, and the construction efficiency is improved. And the influence on the environment is reduced to the greatest extent.
本发明涉及一种节段梁架设的施工方法，包括以下步骤：第一步，在安装跨梁段墩顶安装支座，并按设计调整预偏量；第二步，运梁车将14号梁段运送至架桥机尾部；第三步，尾部喂梁，并在架桥机上进行旋转；第四步，将14号梁段向墩方向移动，预留涂环氧树脂的空间；第五步，依次吊装13号梁段至1号梁段；第六步，涂抹环氧树脂并密贴，张拉预应力束；第七步，放松吊杆，落梁至设计位置，进入下一跨架施工。该方法通过梁上运梁解决不具备梁下运梁条件的节段梁架设问题，满足节段梁快速施工要求，解决跨江河、生态保护区及重要基础设施不具备设置地面临时便道问题，降低地面路线所需要的钢栈桥便道和地面硬化等带来的成本，最大程度减少对环境的影响。
