Original title: Hangzhou Wenzhou High speed Railway Enters the Stage of Joint Commissioning and Test

People's Railway News, Hangzhou, May 22 (Wu Shaoni, Xu Wenfeng) At 6:52 on May 18, the first inspection train left Tonglu East Station and drove along the Hangzhou Wenzhou High speed Railway to Wenzhou North Station to inspect the track, catenary and telecommunications equipment, marking that Hangzhou Wenzhou High speed Railway officially entered the stage of joint commissioning and test.

Hangzhou Wenzhou High speed Railway starts from Hangzhou Tonglu East Station in the north, passes through Pujiang County, Yiwu City, Dongyang City, Pan'an County, Jinhua City, Xianju County, Taizhou City, to Wenzhou North Station, and then extends to Wenzhou South Station by using the existing Hangzhou Shenzhen Railway; The new main line is about 260km long, with a design speed of 350km/h. The whole line is equipped with 9 stations, 81 tunnels, 117 extra large and medium bridges, and a bridge tunnel ratio of 94.5%. Some tunnels are shallowly buried under eccentric pressure, with broken rock strata, developed joints, many surrounding rock sections, poor stability, large topographic relief and complex geological conditions. The constructors adopt the method of "three-dimensional construction, cross operation and countdown" to carry out precise monitoring and measurement every day. Through comprehensive geological forecast such as advanced horizontal drilling and geological sketch, they accurately grasp the geological and hydrological conditions in front of the face in advance, and timely adjust the support parameters and construction countermeasures; Intelligent monitoring and information system, dome roof intelligent air raid shelter system, full face 3D scanner and other technologies are used to realize mechanized, information-based and intelligent control of tunnel construction and effectively ensure the quality and safety of tunnel construction.

As an important part of the Yangtze River Delta inter city railway network, Hangzhou Wenzhou high-speed railway is the fastest way to reach Hangzhou, Jinhua Yiwu and Wenzhou in Zhejiang Province within one hour. After the high-speed railway is completed and put into operation, Hangzhou, Jinhua, Taizhou, Wenzhou and other places will have rich tourism resources connected into a line. Xianju, Pan'an, Dongyang, Pujiang and other places along the line will officially enter the era of high-speed railway, which is of great significance for improving the regional road network layout and promoting the coordinated development of the Yangtze River Delta urban agglomeration.
