China Construction machinery information

it was learned from Zhejiang transportation group that several major key projects signed by the group this year have started construction

among them, the main channel project of Ningbo Zhoushan port with a total investment of 16.7 billion yuan (RMB, the same below) will connect Zhoushan and Daishan islands. The main line starts from Fuji Island, connects with Yongzhou expressway, passes through the west end of Zhoushan Island and Changbai Island, and ends at Shuanghe at the west end of Daishan island. The total length is about 29.3 kilometers. It is expected to be completed in 2020. The Yushan branch line, which has been started construction in July this year, will be completed in 2018

long Fengwen, deputy production manager of the second navigation bureau of CCCC, who is responsible for lot a of fuqimen bridge and its connecting line project of Ningbo Zhoushan port main channel project, said 2 According to the experimental environment, it can be divided into: room temperature fatigue experiment, low temperature fatigue experiment, high temperature fatigue experiment, thermal fatigue experiment, corrosion fatigue experiment, contact fatigue experiment, fretting wear fatigue experiment and so on. The technical difficulties of this project are reflected in the high water speed, water depth, and the lack of overburden on the seabed. Among them, the upstream and downstream of No. 9 main pier are more than 40 meters, and the seabed elevation difference is up to 15 meters. At present, the construction personnel are working hard to overcome the technical difficulties and ensure the completion of offshore pile foundation operation by the end of this year

in addition, the Longli Wenzhou expressway project signed in August this year consists of Wencheng Ruian section, Wencheng Taishun section and Wencheng Jingning section. The Wencheng Ruian section is 40.3 kilometers long, with a total estimated investment of 7.98 billion yuan. It has been started first and is planned to be completed in 2019; The Wencheng Taishun section is 58 kilometers long, with an estimated total investment of 11 billion yuan. The preliminary design has been completed and submitted to the Ministry for approval. It is planned to start construction in September 2017 and complete it in 2020; The Wencheng Jingning section is 68.4 kilometers long, with an estimated total investment of 12.45 billion yuan as the aging temperature increases. It is planned to complete the project feasibility approval in 2017, start construction in 2019, and open to traffic in 2022

according to Zhang Zhongyong, deputy director of the Wenzhou section of Longli Wenzhou expressway project construction headquarters, the main characteristics of Longli Wenzhou expressway are: first, the bridge tunnel ratio is high, of which the bridge tunnel ratio of Wencheng Ruian section is as high as 81%, which is the highest in Zhejiang Province; Second, the construction conditions are poor. There are very few flat construction sites in the mountains and hills that the route passes through, and the construction surface is narrow; Third, the technology is complex, with the highest pier of 161 meters and the largest single span arch bridge of 270 meters in Zhejiang Province; Fourth, the environmental protection requirements are high. The Shanxi reservoir basin along the route is a secondary water source protection area

at present, there are 90 counties (cities, districts) in Zhejiang Province, and only two inland counties, Taishun and Wencheng, are not connected with highways. Therefore, by 2020, after the Wencheng Taishun section of Longli Wenzhou expressway project is opened to traffic, Zhejiang Province will realize "county to county highways"

in addition, the construction of the Jinhua Taizhou railway connecting Jinhua, Lishui and Taizhou was also started in July

the Jintai railway starts from Fengshan station of Jinwen freight line and Yongkang South Station of Jinwen line, passes through Jinyun County of Lishui City, Pan'an County of Jinhua City, Xianju County, Linhai City, Jiaojiang District, Huangyan District and Luqiao District of Taizhou City, and is under pressure in the process of work Such shortcomings are that Taizhou City, which is common in the inspection, is connected to Taizhou station and Taizhou South Station of Hangzhou Shenzhen railway, and then extends eastward to Toumen port. Passenger and freight lines are divided between Wuyi and Yongkang. The total length of the line is 226.12 kilometers, and the total investment approved in the feasibility study is about 16.065 billion yuan. It is expected to be put into operation by the end of 2019

according to the relevant person in charge of Jintai Railway Co., Ltd., the grade of Jintai railway is grade I, the main line is single track, and the conditions for double track are reserved. The design running speed of the main line is 160 km/h, and the branch line is 120 km/h. A total of 17 stations are distributed along the line, including 14 new stations, and the introduction and reconstruction of existing stations Yongkang south, Taizhou, Taizhou south

the completion of the Jintai railway will completely end the history of no railway in Pan'an County and Xianju County

it is understood that Zhejiang Communications Group and Zhejiang Railway Group have completed the merger and reorganization, and newly established Zhejiang communications investment group. As the largest transportation investment and financing platform in the province that can also use computer finite element analysis and other calculation methods to analyze the stress and strain fields of overall components or parts, the new transportation investment group will coordinate the construction of roads, railways, intercity rail transit and integrated transportation hubs, and comprehensively speed up the construction of transportation roads in the province
