Construction device and construction method for river-crossing special-shaped steel bridge
The invention discloses a construction device and a construction method for a river-crossing special-shaped steel bridge. The construction device comprises a plurality of sections of temporary cofferdam areas arranged at the bottom of the steel bridge, wherein supporting frame bodies are installed in the temporary cofferdam areas according to the design positions, and each supporting frame body comprises a steel stand column, a steel cross beam supported on the steel stand column and a steel inclined support connected between the bottom of the steel stand column and the end of the steel crossbeam; the supporting frame body and the pier are connected into a whole; gantry crane rails are arranged on the two sides of the supporting frame body, and hoisting equipment and a gantry crane are movably arranged on the supporting frame bodies of different sections according to the installation progress. By means of the supporting frame body, wading operation is reduced, cofferdam and river bottom foundation treatment is reduced, the influence of the river water flood season is avoided, and the construction period is shortened. The gantry crane is used for installing steel beams, arch rings,hanging rods and other components, the walking characteristic of the gantry crane is utilized, the horizontal transportation and perpendicularity problems of steel beam sections and other componentsare solved, the configuration of other professional transportation vehicles is avoided, and the transportation efficiency is improved.
一种跨河异形钢桥梁的施工装置及施工方法，施工装置包括设置在钢桥梁底部的多段临时围堰区，在临时围堰区内根据设计位置安装支撑架体，支撑架体包括钢立柱、支撑在钢立柱上的钢横梁，以及连接在钢立柱底部与钢横梁端部之间的钢斜向支撑；支撑架体和桥墩连接形成整体；支撑架体的两侧设置龙门吊轨道，吊装设备以及龙门吊根据安装进度移动设置在不同段的支撑架体上。本发明通过支撑架体减少了涉水作业，减少了围堰及河底基础处理，避免河水汛期的影响，缩短施工工期。使用龙门吊安装钢梁及拱圈、吊杆等构件，利用龙门吊的可行走特性，解决了钢梁分段和其他构件的水平运输及垂直度问题，避免了配备其他专业运输车辆，提高了运输效率。
