Description

(54) УСТРОЙСТВО ДЛЯ СТАБИЛИЗАЦИИ ГИДРОДИНАМИЧЕСКОГО ДАВЛЕНИЯ В КОЛЕНАХ ТУННЕЛЬНЫХ ШАХТНЫХ ВОДОСБРОСОВ(54) DEVICE FOR STABILIZATION OF HYDRODYNAMIC PRESSURE IN KNEES OF TUNNEL MINE WATER DISCHARGES

Устройство состоит из трубопроводной системы 1, один конец которой св зан через отверсти  2 с выпуклой внутрь тракта частью колена 3 и началом туннел  4 в нескольких местах, а другой через отверсти  5 - с туннелем 4 на некотором (от 2 до 3 диаметров) рассто нии от колена 3,The device consists of a piping system 1, one end of which is connected through apertures 2 with a part of an elbow 3 convex inward and the beginning of tunnel 4 in several places, and the other through openings 5 with a tunnel 4 at some (2 to 3 diameters) from knee 3,

Устройство работает следуюишм образомThe device works as follows.

При работе тракта в своде горизонтальной части колена 3 и начала туннел  4 в их разных поперечных сечени х образуютс  вакуумные зоны, чередующиес  с зонами положительного давлени . При этом в поперечных сечени х, где наход тс  одни отверсти  2, через последние гаситс  вакуум за счет воздуха или жидкости, поступающих по другим отверсти м 2, св занным с другими поперечными сечени ми, где по вл етс  положительное давление. Причем, если во всех поперечных сечени х тракта, в которых установлены отверсти  2 системы трубопровода 1, по вл етс  только вакум , то он гаситс  жидкостью, поступаюьщей из туннел  4 через отверсти  5.When the path is operated in the arch of the horizontal part of the bend 3 and the beginning of the tunnel 4, vacuum zones alternate with zones of positive pressure in their different cross sections. At the same time, in cross sections, where there are only apertures 2, vacuum is extinguished through the latter through air or liquid, which flows through other openings 2 connected to other cross sections, where a positive pressure appears. Moreover, if in all the cross sections of the tract in which the openings 2 of the pipeline system 1 are installed, only vacuum appears, then it is extinguished by the liquid coming from the tunnel 4 through the openings 5.

Предлагаемое устройство позвол ет уст- ранить пульсации вакуума и давлени , повысить пропускную способность тракта и предотвратить кавитадионную эрозию колена и туннел .The proposed device allows to eliminate the pulsations of vacuum and pressure, to increase the capacity of the tract and to prevent cavitational erosion of the knee and the tunnel.
