Group 1 - The project in Saudi Arabia's Red Sea region aims to create a comprehensive tourism city featuring 50 hotels, over 1,000 residential units, and an international airport, aligning with Saudi Arabia's Vision 2030 focused on "green ecology" [1] - The project is being constructed by China Harbour Engineering Company and China Communications Construction Company, involving multiple bridges and roadways connecting various tourist islands [1] - The main bridge spans 2,170 meters and crosses approximately 30,000 square meters of mangrove forest, with a new construction method proposed to minimize environmental impact [1] Group 2 - The prefabricated bridge solution is based on experiences from the Xiong'an New Area, where a similar method improved construction efficiency [2] - The pile-beam integrated machine, weighing 600 tons, can perform piling and beam installation simultaneously, achieving construction efficiency 3 to 5 times greater than traditional methods [2] - An intelligent control system with 12 sensors monitors the machine's stability, ensuring precise movement with a total error margin of no more than 5 millimeters [2] Group 3 - The pile-beam integrated machine, named "Red Sea Vision No. 1," was specifically developed for the Red Sea tourism project and has successfully completed several key milestones since its deployment in June [3] - The use of Chinese manufacturing equipment has not only enhanced construction efficiency but also effectively protected the local mangrove ecosystem, showcasing the commitment to green construction practices [3]
