With the development of science and technology, new cities constructed with high technology will appear on land, at sea, in the air, and underground. The top-covered city with automatic temperature control Vermont, USA, built a world-famous top-covered city called Willowsky. The city has more than 10,000 residents and occupies an area of 880 acres. A huge roof frame was placed over the city of Wailusk. It was an umbrella-shaped vault with a center 67m above the ground. The texture of the umbrella was a foamed plexiglass, and the metal frame of the umbrella frame stood on the ground in a longitude and latitude. There are 60 nylon ropes that are evenly distributed on it, with umbrellas. The lower end of the rope is wound around the motor to contain the umbrella surface and achieve the purpose of lifting and placing the umbrella surface. When the umbrella support
