Construction method for widening, dismantling and reconstructing suspended beam T-shaped navigation bridge
The invention provides a construction method for widening, dismantling and rebuilding a suspended beam T-shaped structure navigation bridge, the method comprises the following steps: S1, a widening bridge is newly built, and steel trestle platforms are erected on two sides of an original high-speed navigation bridge to construct the widening bridge; s2, traffic conversion is carried out, a half-range old bridge is dismantled, original high-speed half-range traffic flow is guided and changed to spliced wide bridges on the two sides, and the half-range old bridge is dismantled through a dismantling and building integrated bridge erecting machine; s3, a half-range new bridge is built, the new bridge is built at the position of the original bridge by using the dismounting and building integrated bridge erecting machine; s4, traffic is converted, the other half of the old bridge is dismantled, the traffic flow is guided to the widened bridge and the newly-built half of the bridge, and the other half of the old bridge is dismantled; and S5, building of the whole bridge is completed, the other half of the new bridge is newly built, and widening, dismantling and rebuilding construction of the whole bridge is completed. Lower navigation is guaranteed, passing of high-speed vehicles is guaranteed, passing vehicles are not affected in the construction process, construction safety is improved, dismantling and building construction is completed through one dismantling and building integrated bridge girder erection machine, mechanical use is reduced, and economical efficiency is improved.
本发明提供一种挂梁T构通航桥拼宽拆除重建的施工方法，其步骤包括：S1：新建拼宽桥，在原高速通航桥两侧搭设钢栈桥平台施工拼宽桥；S2：交通转换并拆除半幅老桥，将原高速半幅的车流导改至两侧拼宽桥上，采用拆建一体式架桥机拆除半幅老桥；S3：半幅新桥修建，在原桥位置利用拆建一体式架桥机进行新桥的修建；S4：交通转换并拆除另半幅老桥，将车流导改至拼宽桥及新建半幅桥上，拆除另半幅老桥；S5：完成整幅桥修建，新建另半幅新桥，完成整幅桥的拼宽拆除重建施工。本发明既保证了下方通航又保证了高速车辆通行，施工过程中对通行车辆不造成影响，提高了施工安全性，用一台拆建一体式架桥机完成拆除新建的施工，减少了机械使用，提高了经济性。
