Beijing Metro Changping Line South Yanxi Tucheng Station "Zero Sentise" passes through the site of the Yuan Dadu City Wall site

Yesterday, the main project of the Metro Changping Line South Yanxi Tucheng Station was completed, and the subway station "zero sedimentation" successfully passed the site of the city wall of Yuanda.

Under the busy learning bridge, a 35 -meter -deep underground station has begun to take shape. Yesterday, with the smooth completion of the concrete pouring on the platform layer, all the main projects in the Metro Changping Line South Yanxi Tucheng Station were completed, laying a solid foundation for the opening of the traffic in the south of Changping Line. In the future, this station will "shake hands" with Line 10 next to the site of Yuan Dadu City. It only takes 2 minutes to transfer the two lines.

The Xitu City Station of Changping Line is the third -floor island -style station on the ground floor. The geographical environment around the station is complicated. It is close to Xituchenggou and Xuezhi Bridge. Wearing a number of large -diameter municipal rain and sewage pipes, the special and first -level risks are as many as 42 places. In order to reduce the impact on the surrounding roads, the station adopts the construction of the dark excavation method. The bottom plate is 35 meters deep, which belongs to the ultra -deep and ultra -large section structure.

The more special is the location of the station. The east side of Xitu City Station is close to the site of the city wall of the national key cultural relics. The above station is the turning point of the northwest corner of the Yuancheng Wall and the Xituchenggou. The construction site is only separated by a wall from the site park.

"Paste the soil against the cultural security unit, and every step of the construction process must be very careful." Li Haisheng, the manager of the Changping Line of the Changping Line of China Railway Twenty -two Bureau, said that as one of the major risks of the project construction, before the construction, the construction party will be the construction party. Calculate the establishment of an ancient site model on the spot and calculate the two technologies to comprehensively simulate the impact on each link of the construction. Li Haisheng introduced that computer simulation can clearly show the impact of construction on the protection of the site, understand the size of the settlement in advance, guide the optimization of the construction plan, and continuously monitor data during the construction process. In the end, the south extension of the Changping Line successfully passed the ancient sites to ensure the safety of the ancient sites through the construction of zero construction. "We used the most advanced construction technology to protect historical relics, while ensuring that the construction of the main structure of the station was completed on schedule."

It is understood that after completing the acceptance of the station's civil construction project, the Changping Line Xitucheng Station will enter the stage of mechanical and electrical equipment installation and decoration. At the same time, the construction party will continue to promote the construction of the auxiliary structure of the station to accelerate the progress of the project to ensure that all construction tasks are completed as scheduled to complete all construction tasks as scheduled.
