At 9:18 on March 22nd, in the festive firecrackers, the construction of the bridge project was officially opened, accompanied by the slow start of the pile machine on the east side of the canal, marking the first step in the construction of the bridge. The general manager of the company, Liu Guobin, vice president of the general manager, deputy chief engineer Li Jianzhong, director Chung Ping Wang of the engineering management center and the construction and supervision units of the construction and supervision units participated in the commencement ceremony.
The project of star harbour bridge is a nodal project of star port road. It is located in the Bell Tower District of Changzhou city. The Road West is running cattle, east to Sakura and crossing the new Beijing Hangzhou canal. It is the main traffic main road of the East and west of the bell tower to Changzhou City, and the important traffic function connecting the main city and the Changzhou city fast road system. It is Changzhou The key construction project of the urban construction system in 18-19.
The star harbour bridge crosses the Grande Canale, Beijing. The navigational grade of the river is grade III. its navigational clearance is 70 x 7m. The length of the bridge is 496m, the span distribution is: 2 x 30m+3 x 30m+ (50+120+50) m+4 x 30m, the main bridge is the beam arch combination system steel bridge, the lead bridge adopts the prestressed concrete section continuous box girder. The main bridge is a continuous steel box girder with variable width and equal section. The girder height is 3M, the width of the bridge deck is 39.3 to 45.8m, and the main span bridge is partially hollowed out. The main bridge is erected by pushing steel box girder, then the arch rib, connecting rod and tension hanger are installed. The construction of the bridge is cast in place of full hall support. W and V piers are adopted in the main bridge piers, and double column piers are used in the diversion bridge. The gravity type abutment is used in the abutment and the bored pile is used in the whole bridge foundation.
The total investment of the Hong Kong bridge project is 238 million yuan, and the planned construction period is 637 days. It is reported that the project is not only the bridge project with the highest cost of the mono - body except the viaduct in the history of Changzhou city construction, but also the bridge project with the greatest difficulty in construction. In the construction of the Hong Kong bridge, the advanced steel box beam pushing technology will be adopted. This is the first time in the history of bridge building in Changzhou city. The top push weight is also in the forefront of the same kind of push project, reaching 6169T. In view of the complicated stress condition of W pier, there are many technical difficulties to overcome during the construction process. At the same time, the high voltage transmission line parallel to the bridge position and the net distance of only 47.2 meters wide, as well as the dense ship flow of the Beijing Hangzhou canal, have raised the difficulty of the construction of the top and hoisting of the steel box girder, which is a huge challenge for the engineers of the construction.
On the commencement ceremony, the project department reported on the overall construction idea, and summarized the key points and difficulties in construction. The company leader also carried out the work mobilization for all the personnel in the project department, hoping that all of us should take the spirit of never slack, carry on the heavy burden, overcome the difficulties of the project and complete the construction task successfully. After the end of the mobilization, all of us have made great efforts to make every effort to overcome the difficulties, complete the construction tasks given by the company and make unremitting efforts to realize the Changzhou municipal dream of the "100 year old shop". |
