Description

Flowing water barrier

The present invention relates to a bird shielding membrane which is installed in a place such as a river where there is almost no current flow to prevent water from flowing down.

In general, there is an antifouling membrane installed to prevent the discharge of polluted water during river construction or coastal pier construction.

However, there is a problem that the anticorrosive film such as the prior art described in the patent literature of the prior art can not prevent the algae from flowing down completely.

Therefore, conventionally, in the river construction, it is necessary to make a simple embankment at the upstream point above the construction point so that there is no water flow, and then the construction is completed at the downstream point and the simplified embankment at the upstream point must be removed again. Which is problematic and inefficient.
