- Abstract:
- The design flow of an oceanarium seawater intake project in a coastal tourism resort is 400 m3/h. However, the project is located in a sandy and gravel coastal zone, which is easily affected by adverse environmental impacts such as silt deposition and fouling organism growth. To prevent seawater impact, silt deposition and fouling organism growth, the design of water intake, gravity self-flowing pipe and land pumping station was analyzed. The water intake adopted a large diameter steel pipe pile structure accompanied by measures such as horn-shaped pipe inlet and sacrificial anode anti-corrosion to reduce seawater impact. The gravity self-flowing pipe was made of polyethylene with a suitable pipe diameter to reduce the impact of fouling organisms, and multiple laying methods were adopted to alleviate the impacts of silt deposition and gas gathering. The land pumping station was equipped with backwash function which was operated in conjunction with sterilization measures to prevent pipeline blockage. Finally, the paper put forward an overall design scheme of water intake project adapted to the sandy and gravel coastal zone.
