The main body of two rod-arch Bridges in Cuizhai South area of Jinan starting area has been completed
Recently, two rod-arch Bridges in the first phase of the municipal project in Cuizhai South Area of Jinan starting Area have completed the main construction after overall careful planning and careful deployment, laying a foundation for the full opening of municipal roads in this area.
According to the introduction, the first phase of the municipal project in the south area of Cuizhai contains 9 roads, with a total length of 12.457 kilometers, including Cuiqing Road, Cuiqing Branch Road, Trunk Road 1, Jieying Road, North Boundary Road, Hengshi Road, City Exhibition Hall Ring Road, West Ring Road, and Water Plant South Road. As an important part of the city road network, the two arc bridge bridge located in waterworks south road and XieYing road across the qing ning groove position, waterworks south road arch bridge span 51.5 m, the upper structure for Nielsen system arc bridge, rise-span ratio of 1:5, 53 m XieYing road arch bridge spans, the upper structure for Jane branches, hanging, rise-span ratio of 1:5.
According to the introduction, the first phase of the municipal project in the south area of Cuizhai contains 9 roads, with a total length of 12.457 kilometers, including Cuiqing Road, Cuiqing Branch Road, Trunk Road 1, Jieying Road, North Boundary Road, Hengshi Road, City Exhibition Hall Ring Road, West Ring Road, and Water Plant South Road. We are strict in the process of bridge transport at each link of transportation, safety technical clarificaiton, equipment daily check and so on related work, in the process of construction, strictly according to the expert evaluation of construction plan execution, and entrust the third party testing unit for follow-up testing, percent of pass is up to 100%, to ensure that the whole arch bridge construction meet the safety and quality standards. As an important part of the city road network, the two arc bridge bridge located in waterworks south road and XieYing road across the qing ning groove position, waterworks south road arch bridge span 51.5 m, the upper structure for Nielsen system arc bridge, rise-span ratio of 1:5, 53 m XieYing road arch bridge spans, the upper structure for Jane branches, hanging, rise-span ratio of 1:5.
Both arch Bridges are constructed by direct hoisting with brackets. "The main steel beam of Shuichang South Road is divided into two overhangs and middle main beams, which are divided into 30 sections, the arch rib is divided into three sections, the wind brace is divided into three sections, and the steel arch on each side of Jieying Road is divided into five sections." In the project construction site, the workers take the section as the unit, first longitudinal ring, first structure after plate seam, first welding welding with large amount of fusion, after welding welding with small amount of fusion, methodically lift welding work. During the hoisting and welding process, the elevation of steel box girder, arch rib, arch rib axis, foundation settlement and arch seat movement were observed in real time to ensure the safety, stability and quality of the whole process.
The reporter from Jinan Starting Area Financial Media Center learned on the scene that STC ultra-high performance concrete is used in the pavement of Shuichang South Road arch bridge deck. In the process of paving, the project adopts the STC intelligent vibrating leveling machine to ensure the full density of STC through high-frequency vibration and realize the precise control of the paving thickness. Hold the STC with high temperature steam curing of concrete, steamed keep a long time, high maintenance requirements, in order to ensure the maintenance of steam supply large area, each point temperature of curing condition, the scene with the method of points warehouse, warehouse set up to monitor the temperature automatic control system of steam and ensure the warehouse temperature equilibrium, guarantees the construction efficiency and construction quality. "In the construction process, we attach great importance to safety and environmental protection work, according to the '6S site management', in accordance with the principles of efficiency, persistence and beauty, always keep the site clean and safe, for Jinan starting area to maintain blue sky, white clouds, clear water and green mountains to contribute to the normal.
