- Title:
- Design of Small Diameter Gravity Flow Water Intake Project in Sandy and Gravel Coastal Zone
- 摘要:
- 某滨海旅游度假区海洋馆海水取水工程，设计取水量400 m3/h，位于砂砾质海岸带，极易受泥沙淤积及污损生物生长等不利环境影响。针对防海水冲击、防泥沙淤积及防污损生物等目标，对取水口、重力自流管及陆域泵房进行设计分析。取水口采用大直径钢管桩结构以降低海水冲击影响，并辅以羊角状管道入口及牺牲阳极防腐措施；重力自流管选用聚乙烯材质及合适的管径以减少污损生物影响，并采用多种敷设方式缓解泥沙淤积及空气影响；陆域泵房设置反冲洗功能，并与杀生措施配合使用，以防止管道堵塞。最终形成适应砂砾质海岸带的取水工程设计方案。
- 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.
