Two more shield machines in Hohhot also originated on August 15th

Liu Rong, Head of the Shield at the 02 Section of the Rail Transit Line 1 of Hohhot City, said that the “Qingcheng No. 2” shield machine is an earth pressure balanced shield machine for China Railway, with an excavation diameter of 6430 mm and a thrust of 4258 tons. The speed of advancement is 80 mm per minute. From Hudong Road Station to Huimin District Government Station, Hudong East Road Station starts from West to East (ie, the right line) along Xinhua West Street until the Huimin District set up at the crossroads of Bayannaoer South Road and Xinhua West Street. Government station. The interval length is 1198.65 meters. The longitudinal slope of the line is a V-shaped slope. Relatively speaking, the speed of the tunneling of this shield segment with a gradient will be slowed down when the slope changes, but according to the predicted time, the shield machine will arrive at the Huimin District government station within the set range. By then, the "Qingcheng No. 2" shield will be dismantled and assembled in the Huimin District Government Station. From the left line, Hudong Road Station will continue to be used for excavation from the Huimin District Government Station.

On the other side, Changlegong subway station also ushered in another shield tunneling machine after Changlegong station to the left of the exhibition hall station.

It is reported that in mid-July, at the Changlegong Station under the responsibility of the China Railway No. 7 Bureau, a shield machine called the “Korea Youth League” will be launched from the west to the east from the left line. A month later, the shield machine named “Tai Long No. 11” was launched from the right line toward the exhibition hall station, and the origin of the two-line approach was still the first time in Hohhot. To this end, the project leader stated that in order to speed up the tunneling process, the China Railway Seventh Bureau purchased two shield machines, and the two lines were concurrently implemented to realize the passage from Changlegong Station to the exhibition hall station, greatly shortening construction time and ensuring The construction work will be completed within the construction period.

The author also learned that the "Qiongrum" and "Tai Long 11" shield machines are expected to reach the exhibition hall station by the end of September and the end of October respectively. After that, the two shield machines will be lifted and transported back to the western end of the Changle Palace site. After the assembly and commissioning of the tunnel, they will be diverted to the agricultural distribution site on the west side. During the period, since the shield machines cannot be paralleled at the same time, 100 shield tunnels will be excavated from the left line and excavation will be carried out on the right line. This year, the exhibition hall will be stationed at Changlegong Station and Changlegong Station to the Agricultural Distribution Station. Complete the hole in two intervals.
