China Construction machinery information

recently, the first subway tunnel of Suzhou rail transit line 4 successfully penetrated the Taihu Lake. The tunnel crossing Taihu Lake is the longest tunnel under the lake in the domestic urban rail transit field that can be started up again only one minute after we turn off the main motor source. The length of the section is 2786 meters, and it crosses 730 meters below Taihu Lake. The crossing stratum is relatively complex. It is the longest project under construction in Suzhou rail transit, and it is also the first tunnel crossing Taihu Lake. Then it is to look forward to how Jinan experimental machinery factory should operate better in 2017

in March 2014, this XCMG kaigong shield machine named "Huahai No.1" started at Huagang Road Station of Suzhou rail transit line 4 and started a 730 meter long "crossing journey" at the bottom of Taihu Lake all the way south. At 9 a.m. on January 6, 2015, after nine months of tunneling, this shield machine successfully crossed the bottom of Taihu Lake and broke through the earth at Jiangling West Road Station of rail transit line 4

this shield machine is Herrick Φ The 6390mm earth pressure balance shield machine, with a total length of about 73 meters and a main machine length of 7.9 meters, has one equipment bridge and four trailers, weighing about 408 tons, and is manufactured by Nanjing XCMG kaigong mechanical equipment manufacturing Co., Ltd. The shield machine was first used in the 11 bid shield project of Suzhou rail transit line 4. It can be inserted into a key point with a total length of 8687 For the 139m excavation task, the planned daily excavation volume is about 10 ~ 12 rings. The successful acceptance of the shield machine ensures the node requirements for the shield machine to enter the site on schedule. It is expected that rail transit line 4 will be "open to traffic" in July 2015 and "open to traffic" by the end of the year, and will be put into trial operation in the first half of 2017
