АНАЛІЗ КОНСТРУКЦІЙ ГАСНИКІВ НАДМІРНОЇ КІНЕТИЧНОЇ ЕНЕРГІЇ ВОДНОГО ПОТОКУ

Микола Гаркуша

Дорожні водопропускні споруди є наймасовішими штучними спорудами на автомобільних дорогах. Варто зазначити, що нижній б'єф таких споруд працює у складних експлуатаційних умовах, які характеризуються значною нерівномірністю розподілу питомих витрат, високою кінетичністю потоку, насиченістю потоку донними наносами, камінням, сміттям, що спричинює розмивання нижнбого б'єфу споруди та руйнування насипу та штучної споруди. Попередити утворення небезпечних форм руху рідини в нижньому бʼєфі дорожніх водопропускних споруд з металевих гофрованих конструкцій можна шляхом застосування інженерних споруд, що дають змогу змінити механізм руху та швидкісну структуру потоку за водопропускною спорудою, що може бути досягнуто за рахунок влаш тування гасника енергії, який дає змогу забезпечити вирівнювання за шириною відвідного русла витрат, глибин, швидкості та зниження їх пульсації. У статті проведено аналіз конструкцій гасників надмірної кінетичної енергії водного потоку
