The second ring radiating new channel into the new passage into Peng Gaga into the city section project is open to traffic

"Finally, don't go around, and run quickly and comfortably!" Ms. Zhang, who was working in the Southwest Tea City of Chengdu, was surprised to find that it can now reach the work place from the North Third Ring Road to the city, which is much more convenient than before.

On July 11, the reporter learned from the Chengdu Housing and Urban Construction Bureau that the Cheng Peng Gaga's entry into the city project has been opened to traffic across the board. The builders faced the scorching sun and finally completed the construction of the surplus project of the project. Traffic bottleneck in the stone area.

Cheng Peng Gado entered the city section project

Traffic conversion faster

All the bottom roads and ramp bridges are all open

Cheng Peng Gang into the city section project is one of the radioactive fast roads in the "Ring+Shooting" Expressway System of Chengdu Central City. Energy expansion and reconstruction of supporting engineering municipal supporting engineering — business avenue viaduct connection. The end point of the project is located on Dongzikou Road in Central, and it is connected to the Jinfeng Elevator with the existing three -ring Chengcheng Pengli to form a new main channel radiation from the second ring road.

After all the underlying roads and ramp bridges are opened, entering and leaving the city can be converted through A, B, and C3 ramps. The time from the North Third Ring Road to the city to the five -piece stone southwest tea city was shortened to less than 8 minutes, and after the ramp bridge was open, it also means that the vehicle can be passed and down to the main bridge of the Peng Gaifang through the ramp bridges on both sides of the Wufu Tunnel. Five stones and its surrounding areas of traffic organizations, thereby achieving faster traffic conversion.

Bridge pier prefabricated assembly and construction process

The first batch of the Southwest District is the largest

It is understood that this project is the first batch of municipal construction project prefabricated demonstration projects in Chengdu. It is also the first batch of municipal construction projects in the Southwest area to adopt bridge pier prefabrication and construction technology. The bridge pier, cover beam, main beam, and collision wall are all adopted by factory prefabricated and on -site assembly plans. The prefabricated assembly rate reaches 67%, which basically achieves industrialization of production methods, standardization of structural design, factorization of component production, on -site construction assembly, and construction process. Informatization. Through the prefabricated assembly construction process, it not only improves production efficiency, but also reduces the on -site construction noise and dust pollution, reduces the impact of transportation nearby, and create a green and environmentally friendly construction environment.

During the preliminary research stage of the project, Chengdu Urban Investment Construction Group organized design units, universities, and industry experts repeatedly conducted research and demonstration of key technical solutions, and passed material performance tests, connection component performance tests, grouting technology tests, and ruler model static test tests A series of special test studies such as the ruler model seismic test, which clarify the material performance requirements, optimize the process of process, analyze the force mechanism, verify the safety of the structure, achieve rich scientific research results. The application lays a solid theoretical foundation.
