Overpass main beam suspension splicing construction method
The invention provides a viaduct-spanning girder suspension splicing construction method which comprises the following steps: constructing temporary bearing bodies on two sides of an existing viaduct, hoisting a second girder and a first girder in sequence to enable the second girder to be mounted on the temporary bearing body on one side, mounting one end of the first girder on a second suspension splicing section of the second girder through a prefabricated suspension splicing mounting frame, and mounting the other end of the first girder on a second suspension splicing section of the second girder through a prefabricated suspension splicing mounting frame; the other end of the first main beam is installed on the temporary bearing body on the other side, a certain distance is reserved between the first main beam and the side face of an existing viaduct during hoisting, so that interference between hoisting equipment and the existing viaduct is avoided, the sum of the length of the second suspension splicing section and the length of the first main beam is larger than the width of the existing viaduct, and the problem that the main beam is insufficient in length is solved. Due to the fact that the end, extending to the existing viaduct deck, of the first main beam can be fixed to the second suspension splicing section through the suspension splicing installation frame, and through the design of the cross beam reinforcing construction platform and the side face widening section construction platform, it is avoided that a temporary support is arranged on the viaduct deck, and the influence on traffic is avoided.
本发明提出一种跨高架桥主梁悬拼施工方法，在现有高架桥的两侧建造临时承重体，先后吊装第二主梁、第一主梁，使第二主梁安装于一侧的临时承重体上，第一主梁一端通过预制的悬拼安装架安装于第二主梁的第二悬拼段，第一主梁另一端安装于另一侧的临时承重体上，吊装时与现有高架桥的侧面留有一定距离，从而避免了吊装设备与现有高架桥的干涉，第二悬拼段的长度与第一主梁的长度相加大于现有高架桥的宽度，从而解决了主梁长度不足的问题，由于第一主梁伸出至现有高架桥桥面的一端可以通过悬拼安装架固定于第二悬拼段，且通过横梁加固施工平台、侧面拓宽段施工平台的设计，从而避免了在高架桥桥面上设置临时支撑，避免了对交通的影响。
