The construction of the project after the station is fully opened

Recently, the construction of the first phase of Qingdao Metro Line 6 and the construction of mechanical and electrical projects marked the construction stage of the project after entering the station.

The first phase of Line 6 is about 77.5 kilometers, and a total of 7 rail base bases are provided. This time, the Xintong Division Base Base, which started the rail launch operation, applied new energy flash welding equipment and rail vehicles. This is the first time that Qingdao Metro has used this device. Foreign objects, early warning and active protection to improve the safety of the operation area.

In the post -projects such as mechanical and electrical, decoration and rail paving, the Qingdao Metro has established a full -staff positioning system to achieve full coverage of interval, station positioning and communication, full monitoring of large -scale equipment safety elements, full monitoring of construction operations, full -time equipment information information full information Entry, comprehensively integrate construction production data, and achieve a comprehensive grasp of on -site construction.

Various pipelines that run through the stations and tunnels are the "blood" of the subway. Whether the pipeline bracket is safe and reliable to directly affect the normal operation of the subway. To this end, the Qingdao Metro has successfully developed a double -phase stainless steel groove lane, branch shelf and fastener series products with independent intellectual property rights, filling domestic gaps and ensuring the safety and reliability of the project from the essence of materials.

The air -conditioning duct of 170,000 square meters on Line 6 will all realize the factory prefabricated processing and modular installation. In addition, the first phase of the electromechanical installation project uses stainless steel materials instead of traditional galvanized carbon steel materials, which is expected to reduce the amount of steel by 42%, which has significant social benefits and economic benefits.

The subway air -conditioning system is important for later operations. The first phase of Line 6 is the first subway line in China to comprehensively evaporate and condense straight air -conditioning systems. Compared with the traditional method, it is expected to save 15%of energy saving and reduce the area of ​​about 1,400 square meters of the cold water machine room about 1,400 square meters. , Cancel the ground facilities such as cooling towers and reduce the impact on the surrounding environment.

The first phase of Line 6 of the electromechanical project includes the masonry and decoration of the equipment area, the ventilation and air -conditioning system, the water supply and drainage and fire protection system, and the power lighting system. Line 6 built 671 BIM models to achieve venue planning, major solutions, key processes and three -dimensional simulation of the bottom, and provided a full life cycle data model for later operation and maintenance management and asset transfer, forming a set of digital assets.

In addition, Line 6 also uses a variety of prefabricated rail panel beds to spread the concrete "floor" for the track. While improving the quality and efficiency of construction, reducing the later operating noise, reducing carbon emissions, and realizing the prefabricated assembly technology in the track engineering Full application.

The first phase of the Qingdao Metro Line 6 is 30.8 kilometers in length, with a total of 21 underground stations. It is an important part of the Jiaozhou Bay Ring Road Network. As of now, the first phase of Line 6 has achieved 7 stations, 14 single -line interval penetration, interval excavation and 68%, and 65%of civil construction projects.
