国产盾构饱和带压进仓设备“首秀”成功

Group 1 - The core achievement of the "Deep Sea Space Station" is the successful application of domestically developed shield tunneling technology under high-pressure conditions, marking a significant advancement for future underwater tunnel construction and deep underground space development [1][2] - The "Deep Sea Space Station" consists of multiple functional modules, including the Ninghai (living) cabin, the Tanhai (shuttle) cabin, and the Zhenhai (control) cabin, capable of simulating seabed high-pressure environments with a maximum operational depth of 100 meters [1][2] - The project has successfully completed 22 consecutive days of operations, allowing for the inspection and replacement of 46 cutting tools, significantly enhancing the efficiency of the tunneling process [3] Group 2 - The Ningbo-Zhoushan Railway's Jintang underwater tunnel is a key project, with a total length of 16.18 kilometers, including an 11.21-kilometer underwater shield section, facing challenges from alternating soft and hard strata [2] - The "Deep Sea Space Station" integrates deep-sea saturation diving technology with underwater shield tunneling, representing a major innovation through cross-domain technology fusion [2] - The effective working time for pressure-maintained operations has increased from 40 minutes to 8 hours, enabling multiple teams to work in a 24-hour cycle, with the longest operational period reaching 28 days [3]
