swivel beam between yijiang road station and wenhua road station of wuhu track traffic line 2 phase i project,located in jinghu district, wuhu city, anhui province,is one of the key maneuverability projects across the board,the rotating beam is 140 meters long and 9.6 meters,weighs 5800 tons,the beam is more than 30 meters above the ground,70 meters on each side of the pier,such as the giant "bamboo dragonfly".
according to our understanding,as the first straddle monorail swivel beam in china,the project management team's work equipment for the connecting structure of the rotating beam track beam transporter, the lower turntable slideway position adjustment device, the rotating beam pier top rolling element positioning device, the straddle-type monorail rescue channel transporter, the steel track beam device molds, etc.进行科学研究,获得了多项国家专利效果。在5毫米内在正式回合之前建造者还进行了3度试车,全面检查旋转参数和梁结构的稳定性,为这种平稳的旋转奠定了坚实的基础。
根据曾凡冲的说法 中铁上海工程局第一公司副总经理为了确保旋转的准确性,该项目邀请专家对旋转接头和旋转施工组织的关键部分的设备控制进行反复研究。在严格控制混凝土浇筑过程中产生的振动和混凝土固化过程中产生的缩短变形对球形接头承载精度的影响后,最后, 球形铰链装置的平面误差控制在0。
"the swivel beam straddles 3 railway business lines and 9 tracks,the surrounding construction environment is complex,the north side is close to and above the house,cross the main road on the south side,the east and west are close to the existing line,the skill requirements and safe production brought great challenges."tang qi, chief engineer of wuhu monorail project department of china railway shanghai bureau no. 1 company said,"to ensure the safety of the rotating beam construction to the maximum limit,let's take parallel with the railway first,after hanging basket operation,completed the construction of 17 consecutive beams in the air,and set up a rolling system between the beam and the top of the pier,perform bridge rotation."
the wuhu track traffic line 2 constructed by donghua metro company of shanghai bureau group and china railway shanghai engineering bureau crosses ningwu railway, ning'an intercity railway, and hehang high-speed railway rotating girder rolling 83° clockwise in nearly 90 minutes.finish accurate docking,it marks the successful completion of the rotation of the first straddle monorail swivel beam in china.
