Project Type: Perimeter Wall
Project Description: This is the largest American-made removable flood wall installation in the world, spanning runways on the banks of the Mississippi River in St. Paul, Minnesota.
Holman Field, St. Paul Downtown Airport
Removable and concrete flood walls
A galvanized steel channel is embedded in the concrete flood wall. The aluminum posts of the removable flood system stack into the channel.
Invisible Flood Control Wall Posts
At 9′ in height, on a project with hundreds of posts, a boom truck is ideal for setting posts.
Channels and Posts
The aluminum stop logs of the removable system are stacked in the embedded channel and a galvanized steel post.
Corner Posts
The regular flood wall posts can accept variations in the angle of the planks, so that variations in the span can be accommodated. For larger jogs in the flood wall, however, special corner posts can fabricated.
Perimeter Flood Barrier Wall
Two long spans of removable flood wall seal the floodplain at Holman Field. The demountable flood system is only half erected in this image.
Airport Runway Flood Wall
The two major flood wall spans tie into an area of high ground. On the near side, the flood wall system ties into a concrete flood wall.
Half Wall
The aluminum planks can be rigged to stack several at a time to expedite the erection process.
