What is a polyethylene floating bridge?
The polyethylene floating bridge is a type of floating bridge mainly constructed from high-molecular polyethylene. The following is a detailed introduction to it:
Materials and Fabrication
- Main Materials: Usually, high-molecular-weight high-density polyethylene (HDPE) is adopted. This is a reinforced material with properties such as corrosion resistance, frost resistance, oxidation resistance, and UV resistance, and it is not eroded by seawater, chemicals, reagents, oil stains, or aquatic organisms.
- Fabrication Process: It is processed through blow molding or rotational molding processes to form various shapes and specifications of floating barrels. These floating barrels are then assembled into a floating bridge.
Features
- Superior Performance: It has excellent weather resistance and impact resistance, and can withstand wave impacts, freezing, ship collisions, etc. It can also resist the erosion of ultraviolet rays, freezing, seawater chemicals, oil stains, etc. The surface of the barrel is designed with anti-slip patterns, and the four corners are in the shape of rounded obtuse angles, which is safe and stable.
- Convenient Assembly: The overall structure is modular. The floating barrels have good versatility and interchangeability, and can be assembled quickly and simply. They can be flexibly changed in shape according to different needs.
- Long Service Life: Under normal circumstances, the service life of a polyethylene floating bridge can reach more than 15 years. Except for natural force majeure and improper human use, it does not require much maintenance and repair costs.
- Environmentally Friendly and Pollution-Free: The polyethylene material itself is non-toxic and odorless, and will not cause pollution to the environment, meeting environmental protection requirements.
Application Areas
- Landscape and Recreation: Landscape floating bridges and sightseeing corridors can be built on the waters of parks, scenic areas, etc., providing tourists with a unique water tour experience. For example, the Wuxianmiao Pedestrian Landscape Floating Bridge in Tongren.
- Traffic Passage: It can serve as a temporary or permanent traffic passage to connect both banks of rivers and lakes, facilitating the passage of pedestrians and vehicles.
- Support for Water Facilities: It is used for the construction of yacht marinas and Floating Docks, providing a platform for ships to dock and moor. It can also serve as the basic structure for water fishing platforms, water stages, etc.
Success Stories
- The Floating Bridge on Lake Iseo, Italy: In 2016, the large-scale art work "The Floating Piers" by artist Christo was presented on Lake Iseo in Italy. The floating bridge was mainly composed of 220,000 high-density polyethylene cubes joined together, and covered with 100,000 square meters of yellow fabric. It attracted a large number of tourists during its opening to the public.
- The Wuxianmiao Pedestrian Landscape Floating Bridge in Tongren: Located in Bijiang District, Tongren City, Guizhou Province, it is 130 meters long and 3 meters wide, with a traffic width of up to 2 meters. The entire floating bridge is made of high-molecular polyethylene material, and can carry a maximum of 300 adults. It is used for activities such as viewing dragon boat races.
