Construction of the first tunnel linking the Yangtze River and the Pacific will begin by the end of this year


A few days ago, the feasibility study report of haitaijiang Channel project (highway part) was approved by Jiangsu Provincial Development and Reform Commission.Construction of the Haitian-Taijiang Tunnel is planned to begin by the end of 2022, with a total construction period of about 72 months.Sea too river-crossing tunnel located in the downstream of the sutong bridge about 8 kilometers, is the National Development and Reform Commission issued by the Yangtze river main river channel layout planning (2020-2035) in male iron compound river channel, a clear channel connection nantong haimen area and suzhou, taicang, changshu, layout, two road, a railway is the Yangtze river section of the first male iron dual-use tunnel,As an important river crossing facility for the general high-speed railway and suzhou-Lake Railway, the construction of the Sea-Pacific River crossing channel is of great significance to improve the regional comprehensive transportation network and make up the short board of river crossing travel. After its completion, it will promote the construction of a comprehensive three-dimensional transportation corridor and strongly promote the regional integrated development of the Yangtze River Delta.Haitaijiang-crossing highway tunnel has a total length of about 11.2 kilometers, of which shield section is about 9.3 kilometers, with an outer diameter of 16 meters. It is the largest and longest road shield tunnel crossing the Yangtze River in China, and has the characteristics of “long, large, high and deep”.The preliminary investigation of the Haitai River Passage began on July 15, 2021 and was completed on February 23, 2022. It lasted 224 days and created a new record of the most holes and the longest construction period in the history of Yangtze River water exploration.Investigation and construction is mainly located in changshu section of the Yangtze River, a total of 15 construction zones are set up, 515 drilling holes are arranged, the investigation project route from south to north through changshu port special channel, Yangtze River main channel, Baimao Sha north water channel and Changshu port anchorage downstream waters.The construction area is the “throat” of the Yangtze River waterway, where five streams of ships meet. The daily flow of ships on the river is about 3,000, and the largest navigable ship can reach 400,000 tons.During the construction period, the main channel and changshu port special channel occupied several channels, the navigable scale was greatly reduced, and the pressure of water traffic safety supervision and water survey operation only increased.In the process of construction safety supervision, changshu maritime bureau adhere to the “substitution don’t change, change boat transposition” 24 hours a day and night without rest, to “every hole drilling services, to ensure the safety of every second of” work requirements, making a concerted effort to overcome difficult, dissolve the disposal of all kinds of danger to prevent more than 240, for the successful completion of the survey and construction work of the security,It has given a full score of “zero accidents, zero casualties, zero pollution in the water area and unimpeded navigation”.Statement: The copyright of this article belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through email, we will deal with it in time.Email address: jpbl@jp.jiupainews.com
