Weilai high speed railway has made new progress! Key points of Laixi section
Qingdao daily / Qingdao view / Qingdao daily online news on November 18, at the construction site in Laixi, the first dragging of the 1-96m single track simply supported steel truss girder of the Qingrong down link of Weilai high speed railway across the Qingrong railway super major bridge was completed successfully A 6031 a 6031 Weilai Qingrong down connecting line spans the 1-96 meter single track simply supported steel truss beam of Qingrong railway super major bridge, which spans the existing Qingrong intercity railway. It does not have the conditions for in place assembly, so it is necessary to adopt dragging construction technology. Due to the limitation of the site, it does not have the condition of assembling 48 m guide beam and 96 m steel truss beam at one time, so the first dragging operation of steel truss beam is carried out by dragging construction at different times, and the guide beam is pushed out of the 58 pier cantilever about 18 m long, so as to leave space for the subsequent assembling operation and dragging construction of steel truss beam
the construction time is tight, the task is heavy, the safety risk is large, and the preparation work in the early stage of construction is very heavy. For this reason, Qingdao company of China Railway 10th Bureau has formulated a detailed and feasible construction plan, which is closely organized and carefully deployed. Seven construction teams have been set up, including drag technology, monitoring and measurement, safety and environmental protection, construction protection, materials and equipment, logistics support and emergency response. The command system has been refined. By defining the division of labor, the number of monitoring and measurement instruments has been increased, and the deployment of field personnel has been strengthened to ensure that The success of one stage dragging provides valuable technical parameters and construction experience for the second dragging of the subsequent 60m steel truss beam
