AI Technical Summary

Technical Problem

Existing water stop devices require manual operation and mechanical power to prevent flooding into the inside of walls, which is impractical in situations where human intervention is not possible, such as at night or during heavy rainfall.

Method used

A water stop mechanism that includes a wall body with a storage groove, a water stop member capable of rising due to water pressure to prevent flooding, and a waterway member that directs water from outside the wall into the storage groove, allowing the water stop member to operate autonomously.

Benefits of technology

The mechanism effectively prevents flooding into the inside of the wall without the need for manual operation or mechanical power, ensuring continuous water stop functionality even during heavy rainfall or at night.

Abstract

To provide a water stop mechanism capable of preventing water immersion to the inside of a wall body without human work.SOLUTION: A water stop mechanism 10 comprises a wall body 22 with an entrance 22E formed, a water stop member 40 movable between a storage state of being stored in a storage groove GH formed on a ground GL of the circumference of the entrance 22E and a water stop state of being lifted from the storage groove GH by water pressure of water guided to the storage groove GH and restricting water immersion from the outside to the inside of the wall body 22 and a water channel member 60 forming a water channel guiding water outside of the wall body 22 to the storage groove GH.SELECTED DRAWING: Figure 1
