Backflow prevention door, harbor-type hume flap *Patent obtained
Coastal work, tidal zone work, and backflow prevention! Just secure it with anchor bolts.
"Do you have such issues?" ◆ Conventional door stop welding fixation products require installation of door stop hardware by specialized contractors... ◆ Despite being a tidal work, the processes, labor, and costs for installing door frames after the secondary concrete formwork, pouring, and curing are burdensome... ⇒ Solve such issues with the port-type flume flap! We have developed the port-type flume flap as an automatic drainage device that can be easily installed without civil engineering work for both new and existing drainage outlets! 【Features】 ■ Structure without beams reduces the impact of waves! Difficult to sway ■ Eliminates installation bolts, improving loosening failures ■ Shortens construction time! Just secure it with the included driven anchor bolts ■ Prevents backflow during high tide ■ Sturdy design! Considers wave pressure (equivalent to a water depth of 25m) ■ Easy installation reduces construction costs *For more details, please refer to the PDF document or feel free to contact us.
