Gelonghui, May 11 | According to Xinhuanet, I learned from China Railway Construction Co., Ltd. on the 11th that China's self-developed undersea tunnel shield machine “Shenjiang-1” is responsible for the construction of the Pearl River estuary tunnel of the Shenjiang Railway. It has now successfully excavated to a depth of 100 meters below sea level. “The entire line of the 'Shenjiang-1' shield was excavated downhill over a long distance and went down to the mouth of the Pearl River. The engineering geological conditions were extremely complicated. At present, the shield machine has excavated a total of 3,320 meters.” Li Bing, project leader of China Railway 14th Bureau, said.
