Guide: the use of the first Wuxi made shield machine marks another major breakthrough in Wuxi's modern equipment manufacturing industry.

the commissioning of the first "made in Wuxi" shield machine marks another major breakthrough in Wuxi's modern equipment manufacturing industry. On the morning of July 16, the first shield machine jointly manufactured by Herrick of Germany and Wuxi Juli Heavy Industry Co., Ltd. was slowly started at Xinguang Road Station of Metro Line 1 and heading for Qingming Road station. So far, 8 shield machines have been "lowered into the shaft" for Wuxi Metro Line 1, and 5 of the 17 shield sections have been completed. The subway tunnel is completed by the "iron and steel dragon" at one time. The Xinguang Road Station of Wuxi Metro Line 1 is a standard station with two floors. There are four entrances and exits connecting the surrounding Golden Chamber garden, five-star home and bus stations. Since the construction started in March last year, the construction of the main structure of the station was completed on July 16. Huge pieces of reinforced cement "segments" used for the next stage of tunnel construction were stacked neatly on one side of the construction site

climb down the simple ladder and go deep into the "shield shaft" used to lower the shield machine at the north end of the foundation pit of Xinguang Road station

19 meters deep under the "shield shaft", a long steel dragon lay in front of him, "head" had been inserted into the tunnel, and the long "tail" extended away. According to the project leader of Shanghai construction machinery construction company, the shield machine has a diameter of 6.39 meters, a total length of 78 meters and a weight of more than 400 tons. During shield construction, the shield machine rotates the cutting soil through the cutting head at the front end to drive forward, and the cut muck is transported to the muck truck at the rear, and then lifted to the ground by the gantry crane. After the shield machine drives a certain distance, the excavated space needs to be supported by spliced "segments" to form the tunnel at one time

"underground dragon" made by Wuxi Juli

different from the imported shield machine seen in the past, the logo of "Wuxi Juli" was seen on this "underground dragon" for the first time. "This is the first locally manufactured shield machine in Wuxi, and it is also the first shield machine specially designed to adapt to the geological conditions of Wuxi." Wang Fengliang, chairman of Wuxi Juli Heavy Industry Co., Ltd., introduced that the promotion of Wuxi metro construction has created opportunities for the localization of a number of rail transit equipment manufacturing industries, which is in the medium and high-end market. As the backbone enterprises of Wuxi's local heavy equipment manufacturing industry, last year, they joined hands with the world's leading shield machine manufacturer Herrick of Germany to start the research, development and production of tunneling machinery and equipment and accessories. After more than four months of construction, the shield machine was finally completed on schedule. "Juli heavy industry has strong manufacturing strength and good professionalism. The shield machine manufactured has fully realized the design parameters." Zhibo, President of the partner Herrick Asia, said so

"nowadays, the traffic bottleneck in the second tier cities in China will be alleviated mainly through the construction of rail transit, so the shield machine market will be huge in the next 20 years." Wang Fengliang said that now they have formed an annual production scale of 12 shield machines. Through the continuous improvement of the localization level of subway construction machinery and equipment, they will build the brand of Wuxi shield machine products and expand to the Yangtze River Delta, the national and even the world rail transit market

at present, five subway shield sections have been connected to Wuxi Metro Line 1 with a total length of 29.4 kilometers. The total length of the single line in the shield section accounts for about 16.1 meters. 4. During the operation of the mortar tensile testing machine, there are 17 shield sections, which will be completed by 12 shield machines. According to the relevant person in charge of the Municipal Rail office, this "made in Wuxi" shield machine is the eighth "downhole" machine of Metro Line 1. It will start tunneling from Xinguang Road station, go north through Jincheng Road station, and is expected to reach Qingming Road station at the southern end of the "Taiqing section" at the end of the year. In addition, at present, five shield sections have been completed in the whole line of line 1. According to the project plan, more than half of the shield interval will be completed within the year, and efforts will be made to realize the "tunnel connection" of the whole underground tunnel by the end of 2012 after the purchase of spring testing machines
