The Olympic Sports Road, Taibaihu New District, Jining City can open to traffic across the ancient canal bridge at the end of August

Olympic Sports Road Cross the Ancient Canal Bridge construction site

The October Road Cross -ancient Canal Bridge is a Minsheng Insurance Project in Taibai Lake New District, Jining City. It was listed by the Jining City Government as "2021 -2022 break -through key guarantee projects". It was opened to traffic by the end of December 2022. At present, the main structure of the Olympic Road Steel Box Steel Box Beams has been welded. It is at the construction stage of auxiliary facilities such as bridges and safety isolation railing, telescopic joints, and sidewalk paving. It is expected to be opened to traffic smoothly at the end of August this year.

The Olympic Road across the ancient canal bridge adopts ultra -high performance concrete. For the first time in Jining, it is awarded the Safety and Civilized Standardization site of the Shandong Provincial Municipal Infrastructure Engineering Building in 2021, and the municipal safety and civilized standardization site in Jining City in 2021. It is understood that the east and west of the project will start 8 main and secondary roads in the north and south directions of the Tai Baihu New Area to improve the road network of Tai Baihu Experimental Middle School and Experimental Primary School in Shandong Normal University. Essence

The Olympic Road is across the ancient canal bridge project, from the west station to the south road of the station, the road to the west, the planned road level is the urban sub -road, the planned implementation is 31m, and the new and reconstruction implementation length is 400m. Among them, the road section is 282m long and the bridge section is 118m long. After the bridge runs through, it connects the east to west to the city sports center, the middle school affiliated to the Jining College, the municipal financial center, the mountain division affiliated, the torch road middle school, and the Beihu fire brigade. The people along the route avoid the two traffic main roads of the ancient Canch Bridge by bypassing Beijing -Hangzhou Road and Jining Avenue, which will greatly accelerate the formation of a 15 -minute high -quality living circle for the formation of the surrounding plots.

The Olympic Road cross -ancient canal bridge uses the special construction plan of "steel bridge+ultra -high -performance concrete UHPC pavement with the same life span as the structure of the structure", which is the first time in Jining. Generally, the concrete strength is 50MPa (Magaza), while the UHPC strength can reach 140MPa (Magaza), and the anti -folding strength can reach 25MPa (Mago) or more. This concrete of the same structure as the bridge has higher strength, higher durability, and longer service life. In the construction, some technologies recommended by countries such as high -efficiency welding, water transparent concrete, and cable structure applications are also adopted in the construction. Among them, permeable concrete can not only reduce road area water, but also relieve flood prevention pressure during the flood season, which is a key part of the "sponge city".

It is worth noting that the construction difficulty and workload of steel structure processing are a great challenge. Its welds reached more than 8,000 meters, and more than 80%are level Ⅰ welds. The welding volume is large, the quality requirements are high, and the ultra -thick plate is 35mm, especially the steel box arch is a different type of octagonal gradient structure. The structure is extremely complicated, the weld is diverse, the operation space is small, and the welding difficulty is high. During the construction of the project construction class, China Railway Twenty -Five and Qilu Construction Association and Ningda Steel structure have been organized many times to demonstrate, adopting a number of technologies such as rhino software advance simulation, welding robots, positive and anti -tires, pre -assembly and other technologies, and finally obtained obtained Good effects, and summarize experience from them, formed a scientific and technological achievement.

The war of war and the heat of the heat, another challenge during construction is the rush period. Since the start of the project in August 2021, it has encountered continuous rainstorms and cold winter in summer and autumn. Faced with the bottleneck of effective construction period and fund financing of only 235 days, in order to achieve the smooth passage of the children who enable the children of the Shanshi and Torch Road Middle School in the autumn, the participating units faced the difficulties in front of the challenge. The construction period of the node is saved, the war is saved, the war is severe and the heat, and the heat is persistent in ordinaryness. It is expected to be completed and opened to traffic 4 months in advance.
