Metro Line 3 Zhaolin Park Station was successfully capped!

On August 23, with the high "long arm" of the high-concrete pump truck, the Harbin Metro TJ2-3 bidding project department Zhaolin Park Station of the China Communications No. 1 Public Public Bureau achieved smooth capacity of the main structure. At this point, the two stations of the project department's friendship palace station and Zhaolin Park Station have all been capped, achieving a staged victory.

The total length of Harbin Metro Line 3 is about 32.2 kilometers. It is the only ring line of the Harbin Metro Planning Nine Line and One Ring. It is the largest, most difficult, and most social impact of Heilongjiang Province. Among them, Zhaolin Park Station is the three -story island platform structure of the underground, 150 meters long, 19.9 meters wide, and the maximum excavation depth of 27.6 meters. It is also a key control project for shield machine receiving and starting construction. There are many risk sources and technical problems during the construction process. The construction requirements are high and the construction period is tight. Since entering the market, the project department has strictly adhered to the goal of node, facing risk challenges, Yongke's technical problems, and ensuring construction safety, quality, and progress in all aspects.

Zhaolin Park Station is only 470 meters away from Songhua River. The geology is the full section of the water -rich sand layer. The continuous groundwater has brought great risks to the excavation of the foundation pit. In order to ensure the safety and quality of construction, the project department adopts 64 45 meters deep and 1 meter -thick -thick underground continuous wall to stitch to a tight and tight main enclosure structure, and uses the MJS high -voltage spinning pile grouting work method on the outside of the continuous wall seam. It not only saves materials, but also makes the enclosure structure stronger and waterproof. At the same time, the lowest temperature in Harbin winter can reach minus 30 degrees. When the water -rich sand layer meets the low temperature, the quality of the project is facing a severe test. In order to overcome the impact of frozen fusion and freezing and swelling on the enclosure structure, the project department adopts the international leading ECR testing technology for "comprehensive physical examination" to the station, find weaknesses and timely grouting and reinforcement to ensure that there is no leakage in the foundation pit Water risk. As of now, the project department has realized the "zero leakage" of foundation pits. In addition, high -cold weather will greatly affect the construction quality of the main body of the station and shorten the effective construction period. The project department adopts the heater thermal wind maintenance method and full coverage method to ensure the progress of the project and the quality of concrete pouring.

Zhaolin Park Station is located in the main traffic channel of the central city of Harbin City. It is adjacent to Zhaolin Park and Central Street with a century -old history. Old and old buildings are densely covered. The nearest distance is only 4 meters away. The deep -founded pit excavation construction, the operation of large -scale machinery and equipment, the transportation and storage of material transportation and storage have been carried out. To ensure the stability of the building and the safety of the lives and property of the surrounding residents, the project department has repeatedly invited experts to hold an expert demonstration meeting to confirm the construction plan repeatedly. System, measurement personnel and multi -party monitoring units pay attention to the settlement of the ground and buildings in real time, and take measures in time to ensure that the excavation of the foundation pit is foolproof. During the construction process, the project managers were brainstorming and carefully organized. By optimizing the construction plan, doing practical technical intercourse, and accelerating the connection of the process, they overcome the complex environmental obstacles and smoothly promoted the construction. At the same time, the project department is available on the outside of the construction site to achieve full greening, and introduces a number of measures such as noise dust monitoring, sound barriers, fog artillery machines, spray, and automatic car washing equipment to effectively do a good job of civilized construction and establish a good corporate image.

The main body of this Zhaolin Park Station was capped on time to provide a strong guarantee for the goal of opening to traffic in the northwest of Metro Line 3 in 2024. In the next step, all participants will continue to solidly promote the remaining work, complete the follow -up targets of subsequent nodes high -quality and efficiently, and continue to contribute to the construction of Harbin subway transportation construction.
