September 29, on the occasion of the 40th anniversary of reform and opening up, the diameter of China's China Railway Engineering Equipment Group and China Railway Tunnel Bureau Group jointly developed 15.8 The rice shield machine "Spring Breeze" is off the assembly line in Zhengzhou and will be used in the Shenzhen Spring Wind Tunnel Project.
This is the largest diameter mud-water balance shield machine designed and manufactured by China. Its successful downline marks the design and manufacture of China's shields towards high-end, and further advances China's progress from a manufacturing power to a manufacturing power in the field of underground space development engineering equipment. The large-diameter mud-water balance shield machine has the characteristics of small impact on the surrounding environment and high degree of factory operation. It is a series of cross-river tunnel construction in China. It has a unique advantage and is a high-end equipment that is mainly developed in the “Made in China 2025” plan. Previously, the core technology of the super-large diameter mud-water balance shield machine has been monopolized by a few developed countries. In order to change this situation, China Railway Equipment Organization's superior R&D team has solved a number of core technologies. This equipment combines five high-pressure capacity system integration design, atmospheric pressure tool changer technology, telescopic swing main drive technology, dual gas pressure control technology, and high degree of intelligence to fill the domestic large diameter. The blank of the mud-water balance shield machine.
Qingdao Haikong is a supporting supplier of well-known air compressors such as Atlas and Ingersoll Rand, and has long participated in the shield project. , China Communications Tianhe, Shanghai Tunnel, Sansan Industry, Northern Heavy Industry, and Tiejian Heavy Industry China's six major shields ace army provide various pressure vessels. With high-quality products, Qingdao Haikong has helped China independently develop the largest diameter mud-water balance shield machine project, contributing to China's challenge to more world-class projects.
