Just secured with anchor bolts. Yamato's anchor-type hume flap.
To prevent backflow from rivers into drainage ditches during water discharge, various gates are installed at the drainage outlets. Among these, it is common for small drainage outlets to have flap gates that automatically open and close based on the difference in water levels inside and outside. In this case, although the gate itself is quite small, the construction involves significant ancillary work such as pouring the necessary concrete for installation, and sometimes temporary closures or the use of drainage pumps. Our company has focused on this issue and developed this anchor-type hume flap as an automatic drainage device that can be installed at existing drainage outlets without the need for civil engineering work.
