PURPOSE: A silent water gate is provided to prevent deformation of the material for operating the water gate and the foreign material from being stuck in the downstream. CONSTITUTION: A silent water gate comprises a water gate main body(10), a support(20) for blocking the foreign substances, and a driving unit. The water gate main body is placed in the width direction of the river and the bottom thereof is hinge-coupled on the river. The support induces the water and the foreign material going over the water gate main body not to soak to the bottom of water gate. The driving unit includes a movable cylinder(40) and a main cylinder(30). The movable cylinder is installed in the downstream of the water gate main body along the width of the water gate main body at a constant interval. The main cylinder sets up the water gate main body and blocks the foreign substances and sets up the support. |
