The expansion of Line 13 and the promotion of the first shield tunnel will build a quick passage between Huitian area and Haidian Software Park.

  Original title: The expansion and upgrading of Line 13 and the completion of the first shield tunnel will build a shortcut for Huitian area and Haidian Software Park.

  After the capacity expansion and upgrading project of Beijing Metro Line 13, the tunnel between Changcun Station and Xinlongze Station was completed on August 15th, which is also the first tunnel section opened by Line 13. At present, the main structure construction of the new section of the capacity expansion and upgrading project of Line 13 has entered the stage of full sprint.

  On the morning of August 15th, at the construction site of Houchangcun Station, the shield machine that has just completed tunnel excavation has stopped firmly in the receiving well. After dismantling, it will be transferred to continue the shield construction from Houchangcun to Software Park.

  The capacity expansion and upgrading project of Line 13 is the largest existing line reconstruction project in China. The relevant person in charge of the 14th Bureau of China Railway, the construction unit, said that the through tunnel spans Changping and Haidian districts, and there are many underground pipelines along the construction line and the construction environment is complicated. Since its launch in October 2022, the maximum settlement data of two shield machines have been controlled within 2 mm in the process of crossing the first-class risk sources such as Beijing-Xinjiang Expressway ramp and Houchangcun Road for a long distance, and the road surface has not been deformed, and the traffic above has not been affected.

  The capacity expansion and upgrading project of Line 13 is in the existing Xi ‘erqi-Long Ze-Huilongguan Station section of Line 13, with 19 new stations, 29 kilometers of new lines and 34 kilometers of reconstructed lines. From the route map, the project is to split the inverted U-shaped line of the existing Line 13, and build the "X"-shaped east and west transverse lines between Line 16 and Line 17, respectively, from Chegongzhuang via Xizhimen and Xinlongze to Tiantongyuan East, connecting the western section of the existing Line 13, Tiantongyuan and Huilongguan areas; From Malianwa Station of Line 16 in Haidian District to Dongzhimen Station via Xinlongze, it connects Shangdi Software Park, Huilongguan, Tiantongyuan and the eastern section of Line 13 in series. The split two lines have the conditions of interconnection and intercommunication, and at the same time, the cross-line operation conditions are reserved, which can realize cross-line organization and operation.

  According to the relevant person in charge of the Municipal Major Project Office, after the completion of the capacity expansion and upgrading project of Line 13, it will effectively solve the problems such as poor return conditions of trains at Xizhimen terminal, inability to shorten the departure interval and crowded cars on Line 13. Build fast travel conditions between Tiantongyuan area in Huilongguan, Changping District and Haidian District Software Park area, and focus on strengthening the connection between large residential groups in the north and Shangdi Software Park, Zhongguancun and other employment-concentrated areas, greatly shortening the travel time between regions and improving the travel efficiency of citizens along the line. At the same time, it will further improve the rail transit network in the northern region and improve the rail transit service level.

  According to the relevant person in charge of the Second Branch of the Beijing Railway Company, the capacity expansion and upgrading project of Line 13, as a "smart site" demonstration line of Beijing rail transit, uses the "smart site" management system in the whole construction process, effectively improving the safety and quality management level of the construction site and ensuring that the construction production is always in a state of controllable safety and quality.
