Content Validity:In the mountain city of Chongqing, a new engineering marvel has emerged. XuGong's intelligent construction technology equipment has achieved the first unmanned paving operation in the Dingjia特长 tunnel of the Wuyun Kai Expressway, overcoming the technological challenge of no satellite signals in mountainous特长 tunnels. This is not only a pride for Chongqing but also a giant leap for intelligent construction technology. Inside the tunnel, technicians control XuGong pavers and rollers with handheld devices, demonstrating powerful collaborative capabilities. This technology not only meets the high demands for positioning accuracy but also solves the tunnel signal issue through radar exploration and Beidou positioning, intelligent perception, and integrated computing, achieving automatic planning of construction paths and efficient coordination of machine groups. XuGong's intelligent construction technology equipment has proven its advancement and reliability in multiple projects, and this successful application in mountainous特长 tunnels marks a new height in full-scenario solutions.
