On July 25, the workers were carrying out the construction of a fully closed sound barrier in the Huangdong liaison line. The full -enclosed frame sound barrier of the construction is 976 meters in length, which is the structure of the top steel frame. The spacing of the steel frame is 4 meters; the total height of the main structure is about 8.60 meters and the span is 11.07 meters. Wait 18 processes; the sound barrier adopts an external -covered sound absorption structure, and the double -layer 50 mm sound -absorbing cotton is used, plus a layer of sound insulation board, which has the characteristics of high noise reduction factor and good sound insulation effect. The construction of the full -blocking framework sound barrier is the first time in the construction of railway projects in the province. After the construction is completed, it is equivalent to building a "sound insulation tunnel" on the bridge of the high -speed rail. Noise reduction 10-20 decibels provide a comfortable and quiet environment for nearby residents.
It is reported that the Huangdong liaison line connecting Huangtai Station and Jinan East Station has recently officially entered the static acceptance stage, marking the basically completion of the project's main project construction, and entering the countdown of operation.
Static acceptance refers to the process of completing the projects of the construction project according to the design, qualified quality, complete equipment installation and commissioning, and qualified inspection and confirmation. It is an important part of the completion and acceptance of the new railway project. The majors of work, communication, signals, power, housing construction, and environmental water protection systems are the process of comprehensively "physical examination" of the quality of engineering construction, equipment installation and commissioning. It is to determine whether the quality of the project is qualified and determine whether the project can Key procedures for operation on schedule.
It is understood that the Huangdong Link Line Project is a key project of the Shandong Railway Construction. It started construction in 2020 and operated 21 kilometers. It is the passenger connection line of the two major passenger stations of Jinan Station and Jinan East Station of the Jinan Railway Hub. The new line of the throat east of the station, walking east along the north side of the Jiaoji Line, folded to the north across the Daxin River, and then across the intersection of the North to Daxin River and the Xiaoqing River to the northeast, accessing the Jiqing high -speed railway Jinan East Station.
After the Huangdong liaison line is completed and opened to traffic, the direct connection between Jinan Station and Jinan East High -speed Railway Station will form a ring passenger layout of Jinan Station, Jinan West Station, and Jinan East Station. Zheng High -speed Railway will form an interconnection of the "Ten" high -speed railway network in Jinan.
