The "One Belt One Road" project of the Three Three Industries set another world record --- "King of Complex Geological Shield" dug 5 kilometers in 10 months
The golden rat gives good news and welcomes spring from all over the world. On January 23, the good news came from the subway extension project of Sansan Industrial Station in Istanbul, Turkey. A 6560mm diameter composite earth pressure balance shield machine in service in the project broke out, setting a world record for continuous excavation of 5 kilometers in only 10 months in the face of high hardness and high corrosion complex strata. When the news came, the whole plant was excited and added a festive atmosphere to the festival's three-three industries.
On August 25, 2018, the cutter head was not worn-the 3rd industrial shield machine-the 12-standard gold flow section of the 1. phase II civil engineering of Chengdu Metro Line 6 was fully connected.
Three three industries joined hands with China railway seventh bureau Hohhot subway line 1 05 standard, three stations 4 intervals, 2017.7.15~2018.10.10 lasted 15 months, 16 times of disassembly and assembly, double line 6km shield interval all through!
On December 29, at the construction site of Caoqiao subway station in South third Ring Road, Beijing, the "Jingtuo No. 2" shield machine manufactured by Sansan Industry broke out, marking the realization of double-line connection of the first section of the shield section of Metro Line 19.
On December 29, at the construction site of Caoqiao subway station in South third Ring Road, Beijing, the "Jingtuo No. 2" shield machine manufactured by Sansan Industry broke out, marking the realization of double-line connection of the first section of the shield section of Metro Line 19. The main construction section of Metro Line 19 is located in the old city of Beijing, and the construction difficulty is unprecedented. There are 1380 risk sources in the whole line, including 19 special risk sources and 433 first-level risk sources, with special first-level risk sources accounting for 32.7 per cent of the total risk sources. During the construction process, long distances pass through the South Third Ring Road, Ma Caohe River, Caoqiao bungalow area and other risk sources, with abundant groundwater, which is one of the most difficult sections of the whole line. This connection
The beginning of the year, Fuzhou meritorious service
On January 6, the 3rd industrial shield machine broke out of the ground, announcing the smooth completion of the second section of Hesha District, Civil Engineering 2 Bid 4 Work Area of Fuzhou Metro Line 6! The total length of the left line of the second section of Hesha District is 868 meters. The actual excavation has been 84 days, with the highest excavation record of 16 rings/day. The crossing stratum of this section is mainly silt, muddy soil and silty clay. Along the way, it passes through Lianxiangang River, 203 Provincial Highway, many dangerous bridges and dangerous buildings, so the construction requirements and risks are extremely high.
Meet Turkey-Help Istanbul New Airport Construction
At the beginning of the new year, good news came from the KEMERBURGZ bid section of Istanbul's new airport. in the first month of its launch, the 3rd industrial shield machine tunnelled 813 meters in 24 days, greatly exceeding customer expectations. Istanbul's new airport is a national key project in Turkey. It has been officially put into operation in early 2019. After the third phase of the project, it will transport 0.15 billion passengers a year and become the largest civil airport in the world.
Quartet auspicious celebration-Suzhou V-TS-08 standard to achieve double interval through
On January 12, the Sansan Industrial Shield Machine successfully completed the double-interval connection in Suzhou V-TS-08 of China Railway Tunnel Co., Ltd. The actual excavation of the project takes 149 days, and the excavation interval is located on the main road of the industrial park. The gas, electricity, tap water, sewage, and communication pipelines overlap and are complicated. There are many interferences in underground construction. It crosses the No.1 bridge of Songjiang Road and crosses the 40-meter river channel. The nearest one is only 3 meters from the structure. The settlement requirements are very strict.
Overcoming Difficulties and Building Meritorious Service in Chengdu -- Three-three Industrial Chengdu Project to Achieve Another Success
Steady excavation when the pioneer, the city subway to make a new contribution. On January 17, the shield section of the right line of Zhangjiasi Station-Zhonghe Station, Bid 14 of Civil Engineering of Chengdu Metro Line 6 1. Phase II Project of San San Industry, was successfully completed. This bid section is contracted by North Railway Construction Engineering, a wholly-owned subsidiary of Sansan Industry. The shield machine is 6.28 meters in diameter from Sansan Industry. It has two stations and three sections, with a total length of 2164 meters. More than 70% of the stratum is a composite stratum, which is difficult to excavate and easy to cause collapse. The maximum longitudinal slope is 28.5 ‰. Finally, the cumulative settlement of all risk sources is not more than 3mm, and the formed segment is almost undamaged and undamaged.
