Changping dear friends, this Thursday Xiaobian brought you about the construction of the new station of Metro Line 13 - Building Materials Chengdong Station, Xiaobian introduced to you in the article that the building materials Chengdong Station will be opened and put into use in 2028 (related reading: Changping new subway station started construction, the opening time is set!) Recently, the reconstruction and expansion project of Line 13 has made new progress: Huilongguan East Station - Tiantongyuan Station and Wenhua Road Station - Huilongguan East Street Station have new news:
Huilongguan East Station ~ Tiantongyuan Station
It is reported that the 10th bid of the expansion and upgrading project of Beijing Rail Transit Line 13 is the section of Huilongguan East Station ~ Tiantongyuan Station, and its main construction task is the shield section of 3847.32 meters long on the left line and 3847.05 meters long on the right line, as well as two open-cut structures in the eight-character open-cut section and the No. 2 section of the wind shaft.
Section 2 air shaft under construction
The No. 2 section air shaft is a separate underground double-layer structure with ventilation and evacuation functions in the shield section of the project, with a length of 60.75 meters, with a total of 4 ground air shafts, 2 safety evacuation ports and 13 civil air defense structures. During the construction of the main structure, faced with a variety of difficulties such as small structure, multiple functions, complex internal construction and limited hoisting on the side of the high-voltage line, with the efforts of all the staff of the project department, the roof pouring was completed in 11 months, marking the successful completion of all the open cut structures of the project department, and creating good conditions for the comprehensive construction of the subsequent shield and contact channel.

Since the project was launched, the builders have deeply analyzed the major difficulties of construction in the construction process, organized on-site construction operations in an orderly manner, overcome many challenges such as high-sensitivity geological environment excavation, crossing soft and hard uneven geological sections, long-distance small curvature and large slope construction, and with the help of engineering and technical means, they have broken through the major risk sources one by one, effectively improved the safety and quality management level of the construction site, and ensured that the construction and production are always in a controllable state of safety and quality.
In the future, the project builder will continue to strengthen process monitoring and quality control, make every effort to strengthen the guarantee of various elements, build a solid line of defense for safe production at all times, comprehensively improve the level of refined management of the project, and promote the construction quality management to a new height.
The shield section formed by the project
Wenhua Road Station ~ Huilongguan East Street Station section
The 6-meter shield segment of the contract section of the 07 bid project of Beijing Metro Line 13 "Wenhua Road Station ~ Huilongguan East Street Station Section" successfully passed the acceptance of the first piece of steel skeleton and three-ring test assembly.
After listening to the introduction of the company's products and development, and the self-inspection and receipt report of the three-ring test assembly, the relevant leaders of the rail company, design, supervision and construction units went to the three-ring assembly site and test site to test the inner and outer diameter, assembly clearance, surface flatness, molding quality and other aspects of the three-ring assembly of the segments in an all-round way;
The expansion and upgrading project of Beijing Rail Transit Line 13 is to split the existing inverted "U" shaped line, and build two new "X" shaped east and west horizontal lines between Line 16 and Line 17. After the completion of the project, it will further improve the rail transit network in northern Beijing, improve the service level of rail transit, improve the traffic pressure in Zhongguancun, Huilongguan, Tiantongyuan and other areas, and better meet the travel needs of citizens.
