The Shenguan No. 6 was launched on 5 August from Working Shaft No. 5 on Lot 6 of the project in Bao\u2019an District, Shenzhen, marking the start of full-scale mechanised tunnelling on the contract.<\/p>\n
The machine will excavate the 8,026.3m section between shafts No. 5 and No. 6, forming a single-bore, double-track tunnel.<\/p>\n
At 13.23m excavation diameter, the CREG-built single-shield TBM is approximately 160m long and weighs around 3,600 tonnes.<\/p>\n
The drive presents a number of technical challenges, with the alignment passing through mixed ground comprising alternating hard and soft strata, as well as hard rock with locally developed fissure water.<\/p>\n
The tunnel will also pass beneath the Shenzhen Metro lines 11 and 20 and the Sui-Guan-Shen Intercity Railway. Other sensitive crossings include under the Fuyong River, additional waterways and densely developed areas containing numerous existing buildings and structures.<\/p>\n
According to CREG, the TBM was developed specifically for the geological and operational constraints of the project and incorporates technologies intended to support automated and intelligent control during the long-distance excavation.<\/p>\n
The 116km Shenzhen-Jiangmen Railway will connect Shenzhen, Dongguan, Guangzhou, Zhongshan and Jiangmen and forms part of the coastal corridor of China\u2019s national high-speed railway network.<\/p>\n
Once operational, the railway is expected to reduce high-speed rail journey times between Shenzhen and Jiangmen to less than one hour.<\/p>\n","protected":false},"excerpt":{"rendered":"
