The first shield machine of the iron construction heavy industry East China manufacturing base went offline

On September 13, the first shield machine of Tiejian Heavy Industry East China Underground Equipment Manufacturing Base was successfully launched in Nantong City, Jiangsu Province, achieving a breakthrough in the local manufacturing of shield machines in Nantong, and developing high-end underground equipment industry in Nantong and East China. Infused with new power.

The first shield machine of Tiejian Heavy Industry East China Underground Equipment Manufacturing Base went offline smoothly

It is understood that the equipment excavation diameter of 6.44 meters, the length of the whole machine is 84 meters, the total weight of about 450 tons, installed power of 1500 kilowatts, will be applied to the construction of Nantong Rail Transit Line 1 tunnel. The whole project has a total of 27 sections with a total length of 34.34 kilometers. The main section is constructed by shield method. The maximum length of the section is 2617.6 meters, the minimum is 515.833 meters, the maximum depth of the covered soil is 23.14 meters, and the minimum buried depth is 7.22 meters.

In view of the characteristics of the project rich water sand stratum, Tiejian Heavy Industry combined with the design and use experience of the previous tunnel boring equipment, the equipment has been customized design, using spoke type cutter head, the cut muck can quickly enter the soil bin, avoiding two The secondary wear and strengthen the anti-spraying measures of the shield machine, making the construction of the shield machine safer and more efficient, and can be quickly burrowed in silty sand and silty clay.

In 2018, the Nantong Municipal Party Committee and the Municipal Government proposed a new round of strategic deployment for the development of key industries of “3+3+N”, and promoted the “smart equipment industry” as one of the three emerging industries. In order to help the development of Nantong's intelligent equipment industry, Tiejian Heavy Industry and Nantong Urban Construction Group joined forces to form a joint venture to establish Tiejian Heavy Industry Nantong Co., Ltd. as the underground construction equipment manufacturing base of Tiejian Heavy Industry. The project was signed from the cooperation agreement to the establishment of Tiejian Heavy Industry Nantong Company, and then the first product was officially launched. It took less than one year to reproduce the “high speed of iron construction”.

Tiejian Heavy Industry Nantong Company plans to produce 13 shield machines for Nantong Metro Line 1

Tiejian Heavy Industry Nantong Company is committed to building a specialized enterprise integrating design, manufacture, sales and service of high-end underground engineering equipment. It will form a full-section tunnel boring machine (shield/TBM) as the core product and pre-buried slot. Roads, underground pipe rack equipment, sponge city equipment and other products parallel high-end underground equipment manufacturing base, determined to better serve Nantong and East China city construction, and fully help Nantong enter the "new era of the subway."

Next, Tiejian Heavy Industry Nantong plans to produce 13 shield machines for Nantong Metro Line 1, and prepare for the manufacture of shield machines for Metro Line 2. (This article comes from Tiejian Heavy Industry)
