37 days ahead of time, the main line of the Danshan Bridge section of Qingyin Highway through

Qingdao Daily/Guanhai News On August 14th, Qingyin Expressway (Danthan Bridge, Xiazhuang Lizhi to Liuting Interchange) Zhongxiu Project Dan Shan Bridge Section Main Project was successfully completed, and the overall construction period was compared to the original period. 37 days in advance.

The G20 Qingyin Expressway is an ecological avenue, landscape avenue, and welcome avenue of Qingdao. Among them, the Danthan Bridge is an important node with a total length of 1,331 meters. Since the completion of the traffic, with the growth of the service life and the increase in traffic, the bridge surface paving has appeared to be different degrees of diseases such as vertical and horizontal cracks, block -shaped cracks, etc. The conventional minor repair and maintenance difficulty to ensure driving comfort and safety. On July 19, the pavement of the Danshan Bridge Bridge of Qingyin Highway for the first comprehensive and systematic improvement and restoration. The point "all opens up, give play to the spirit of" 5+2 "and" white and black ", and use the model of the military regiment and multi -working surface to grab progress.

During the construction process, the Qingdao Transportation Development Group was based on urban renewal and urban construction three years. It fully brought into full use of the implementation and integration of grass -roots party organizations and engineering construction. This time, the construction project has invested 960 construction personnel, 630 construction machinery and vehicles, and a paving asphalt mixture of more than 4,400 tons, repairing 45 pavement diseases with a total length of 2.6 kilometers.

Technological innovation is bright, "7 days" shorten to "6 hours"

In order to further improve the quality of urban functions, build a high-quality people's livelihood project, people's heart engineering, and development engineering, Qingdao Transportation Development Group adopts the most advanced and mature SBS modified asphalt seal, SMA-, the most advanced and mature SBS modified asphalt sealing, SMA- 13 Asphalt Mal -hoof hybrid technology and high -strength fast -coagulative C50 concrete telescopic seam repair technology, breaking the pass bottleneck that needs to be solidified for more than 7 days before traditional concrete, achieves the effect of "3 hours of solidification and 6 -hour use" effect. " The construction period has been strongly reduced.

In order to help create a model of civilized civilization, Qingdao Traffic Development Group adheres to the new concept of creating a "green highway" and in order to assault the small team's centralized construction operation model, and through scientific organizations to realize the implementation of multiple projects and multi -work in the same section under large traffic to achieve the simultaneous cross -implementation of the work and multi -work. The effects of short control time, small traffic impact, high construction efficiency, excellent engineering quality, low safety risk, and good social response. In addition, in the entire construction process, it is equipped with mechanical and equipment such as dry car washing, sprinkler, and fog guns to achieve the "two mistakes" of ecological environmental protection and engineering construction.

"One by one" strong linkage, creating a road of security and peaceful peace

The construction characteristics of the "side by side, while construction" determine the particularity and complexity of the Danthan Bridge. In order to minimize the impact of public travel, Qingdao Traffic Development Group adheres to the work project, the project is monocular, and the list is responsible. By establishing a special work class, running together to establish a set of coordination mechanisms for multi -party coordination, high -speed traffic police, local traffic police, public travel services, news supervision, road production management, obstacle rescue, and toll stations along the route, adhere to systematic collaboration Thinking, truly practicing the concept of "a high -speed road, one thing, one heart, and a family", fully guarantee the maximum and unblocked high speed during the project construction period. Throughout the construction period, a large area of ​​severe congestion has not occurred, and has won the maximum understanding of the general public.

After the completion of the Danshan Bridge of Qingyin Expressway, the Xiazhuang Interchange-Liuting Interchange Line Section, Xiazhuang Interchange Ring and Liu Ting Interchange Ramp will gradually be closed after the completion of the completion of the Danthan Bridge of the Qingyin Expressway. Will be carried out simultaneously. The short -term construction is to be more unblocked. The majority of Si Cheng can understand road conditions in real time through the public account of Qingdao Traffic Broadcasting, Qingdao High -speed Travel Service Platform, Weibo and other channels, and reasonably plan travel routes during the peak tourism season and morning and evening peaks.

The repair project in the Danthan Bridge is a further exploration of the current project construction plan of the large traffic section. The promotion of large -flow road sections and preservation experiences have made Qingdao demonstrations from similar cases of highways in the city and even the province.

Next, Qingdao Transportation Development Group will closely focus on the goal positioning of "the most competitive transportation industry chain development platform", use solid work to face and use achievements to constantly improve road quality and travel experience, and update Qingdao City to update With the three -year operation of urban construction, Qingdao has contributed to Qingdao.
