At the outside venue of the 6th National College Student Geotechnical Engineering Competition "Zhaodi Cup", a seemingly simple screw-lock connector assembly contest ignited the enthusiasm of participating students. The fastest assembly record was repeatedly broken from 18 seconds to 16 seconds to 14 seconds, and finally when a student from Huaqiao University completed the assembly in 12.251 seconds, the audience burst into applause—this number not only set a new competition record but also intuitively demonstrated the core advantage of Zhaodi's screw-lock connection technology.

      “At first, I thought 18 seconds was the limit, but the record was broken again and again.” The contestant's remark revealed the most intuitive advantage of the screw-lock connector.

      In traditional engineering construction, connection methods such as welding and fixing often require professional tools and are greatly affected by operating space, weather conditions, and personnel skills. However, the screw-lock connector adopts a modular design, so even students who are exposed to it for the first time can operate it proficiently after understanding the principle and simple training.

      This efficiency improvement has profound significance in actual engineering. Traditional electric welding pile connection generally requires 2 skilled workers to weld, and the pile connection takes about 30 minutes; after using the screw-lock connector, 2 ordinary workers can complete the operation, and the pile connection time can be shortened to 10 minutes, increasing efficiency by 3-5 times.

Major projects with strict schedule requirements, such as the hockey and baseball/softball venues for the 19th Asian Games in Hangzhou, Shanghai Hongqiao International Airport, Zhejiang Coastal Expressway, Hangzhou-Ningbo High-Speed Railway Passenger Dedicated Line, and Xiamen Xiang'an International Airport, have all adopted Zhaodi's screw-lock mechanical connection technology.

      Behind the efficiency is precise structural innovation. The screw-lock connector consists of a PC embedded in the pile body点赞 (0)
