Guangzhou's first subway loop starts the rail today

On the morning of August 28, the first track of the Guangzhou Metro Line 11 was smoothly laid at the rail paving base of the Yundai Garden, marking that the first subway ring line in Guangzhou officially entered the rail engineering construction stage.

The entire line of Line 11 adopts the ground line launch method. There are 32 stations, 24 transfer stations, 1 vehicle section, and 3 main power stations. The total length of the rail paving is 92.33 kilometers, with 48 groups of roads, 27.452 kilometers of Chisha vehicle section, and 79 groups of Dao forks.

The progress of 6 rail bases on the entire line

Line 11 faces difficulties such as construction period and heavy tasks. The construction unit China Railway Guangzhou Investment Company leads the rails to confirm the construction progress of the civil construction projects every week. Preparation and adjustment of rail paving construction plans.

In order to accelerate the progress of the rail paving, there are 6 rail paving bases across the board, planning 12 dragon door cranes, 36 rail panel cars, 14 new energy rail vehicles, 4 new energy welding machines, and construction peak periods. In the homework surface, 1,200 operators work at the same time.

In order to effectively guarantee and monitor the safety of rail paving construction, the construction unit adopts a comprehensive management system for driving scheduling in the rail area, which can effectively assist the overall operation of the rail area and comprehensively improve the cross -avoidance and transportation of rail engineering and electromechanical installation and power supply projects. Organizational efficiency has greatly improved the level of safety management in the rail area.

The space inside the subway tunnel is relatively small and closed. In order to effectively reduce "carbon emissions", the construction of green environmental protection construction equipment such as "standard rails on the subway concrete" and "new energy rail vehicles" is used to greatly improve the underground operating environment. Protect the operators in good health.

Multiple vibration reduction and noise reduction measures to improve the riding experience

In order to effectively reduce the impact of subway operations on the production and life of residents along the route and improve the sense of experience in passengers, Metro Line 11 sets up a variety of comprehensive rail reducing measures such as medium vibration reduction, higher vibration reduction, and special vibration reduction for the situation along the line.

Among them, the special vibration reducing road bed adopts the cast -in -law structure, and the segmented one -time pouring is formed. It has strong integrity, good vibration reduction and noise reduction effect, high control accuracy, less maintenance and maintenance, upgrading and reconstruction of vibration reduction lane beds in the later stage, etc. advantage.

The Chisha vehicle section is a large double -layer vehicle section. For the first time, prefabricated assembly components are used to carry out factories and then transported to the site installation after factory construction. The track structure of the vehicle section adopts the method of laying vibration pads, vibration reductions, damping rails and embedded orbit, which greatly reduces and improves the impact of rail construction and later operations on the surrounding environment.

A total of 84% of the civil engineering project

As of now, the civil construction project has been completed by 84%. Of the 32 stations, 2 have been opened, 14 have been capped, and 15 are planned for civil construction. One of the remaining 1 is preparing for preliminary preparations; one of the 32 areas has been built and opened. The remaining two are prepared before construction. The construction of the Chisha vehicle section and the entry and exit section is carried out for civil construction. Three stations started the station decoration and mechanical and electrical installation construction.
