CTOnews.com November 6 news, today China Railway Construction Group Corporation survey and design Beijing-Tianjin Binhai New District intercity railway Beichen (excluding) to Binhai New District section (referred to as Jingbin intercity railway south section project) and Tianjin-Weifang high-speed railway project (referred to as "Jinwei high-speed railway") officially started construction.

Construction of Beichen (excluding)-Binhai New District Section of Beijing-Binhai Intercity Railway Started: Design Speed 250km/h

Tianjin-Weifang High-speed Railway is located in the Bohai Rim region of Tianjin, Hebei and Shandong provinces. It starts from Tianjin hub Binhai Station and ends at Weifang North Station of Jiqing High-speed Railway. The main line length is 348.2 kilometers, including 322 kilometers of bridge length, 6.7 kilometers of tunnel and 94% of bridge-tunnel ratio. There are 10 stations along the whole line, 1 bullet train station in Binhai West, 1 parking lot in Dongying South and Weifang North respectively, and the connecting line project with Jinqin High-speed Railway, Jingbin Railway and Jiqing High-speed Railway will be built at the same time.

CTOnews.com learned that Jinwei High-speed Railway is an important component of the skeleton of the "eight vertical and eight horizontal" high-speed railway network, a common component of the Beijing-Shanghai auxiliary channel and the coastal channel, and an important channel for quickly connecting the Yellow River Basin and Beijing-Tianjin-Hebei region in the Outline of Ecological Protection and High-quality Development Planning of the Yellow River Basin. The construction of the project can complement the short board of high-speed railway development in coastal areas such as Beijing-Tianjin-Hebei and Shandong Peninsula, form a new high-capacity fast channel in the eastern part of Beijing-Shanghai high-speed railway in the regional road network, and greatly improve the interconnection level between the Yellow River Delta and urban agglomerations such as Beijing-Tianjin-Hebei and Yangtze River Delta.

Jingu Haihe Tunnel

Jingu Haihe Tunnel is one of the control projects of the whole line, with a total length of 6.66 kilometers, including 6.01 kilometers of shield section, 360 meters of undercrossing water section and 5654 meters of road section. There are existing (planned) municipal, railway and road projects along the line, numerous pipelines and complex construction environment. The tunnel design adopts circular section, reinforced concrete prefabricated segment lining, outer diameter 13.3 meters, inner diameter 12.2 meters.

Dongying Yellow River Gongtie Bridge

Dongying Yellow River Gongtie Bridge is located in Dongying District and Lijin County. It adopts the joint construction mode of highway and railway with a total length of 2230m. It adopts 90+210+600+255+ 105m cable-stayed bridge for highway and railway + 2- 122m simple steel truss beam for highway and railway. The cable-stayed bridge adopts longitudinal semi-floating system, i.e. pier tower consolidation, vertical and horizontal constraints are set between main tower, main pier and main girder. N-type truss is adopted for main truss, truss height is 12.8m, and tower height of cable-stayed bridge is 203.6m. With novel beam design structure, large engineering volume and complex technology, it is the railway bridge with the largest span in northern China at present.
