recently, the national energy strategic channel west east gas transmission line 3 successfully crossed the Yellow River by shield for the first time, and the Zhongwei Yellow River Shield Tunnel, a key control project of west east gas transmission, was completed

the third west east gas pipeline project will transport Central Asia natural gas and Xinjiang coal to gas to the central and western regions, Yangtze River Delta and southeast coastal areas along the line. Zhongwei Yellow River Shield Tunnel Crossing Project is a key control project of the west section of the third west east gas pipeline. It is the 15th shield tunnel project undertaken by the fourth pipeline company. It is the shield project with the largest diameter of small section shield machine (4.25m is the price of foam granulator) in the construction of domestic energy channel so far

the crossing section of Zhongwei Yellow River Shield is located about 500m upstream of Zhongying Expressway Bridge in Ningxia, belonging to Shapotou Water Control Project reservoir area, which is a national 5A tourist attraction. At the same time, the project also passes through two national protection zones, the Shapotou National Nature Reserve Experimental Zone and the Lanzhou catfish national aquatic resources protection zone in the Weining section of the Yellow River.
