FIELD: construction.SUBSTANCE: method to wash over earth works in the form of narrow-profiled dams consists in supply of pulp from the end of the main pulp line and dispersed release of pulp taken from the lower part of the main pulp line, from distributing pulp lines. The narrow-profiled dam is washed over with the help of a distributing device, making it possible to fractionate and wash over side prisms from sorted fractions, and the nucleus of the dam may be washed over from the remaining mass of the solid phase of the pulp. The distributing device is the end section of the main pulp line, to which via a socket rigidly fixed in its lower part there are two distributing pulp lines connected, being arranged in parallel to the main pulp line, with varied distance between them. In front of the inlet hole into the socket there is a guide element fixed rigidly with crescent shape, inclined at the angle of 25?30° towards the protective grate. The guide element is made of sheet wear-resistant steel with thickness of 8?10 mm, height of 50?70 mm, length equal to width of the inlet hole of the socket. The distributing device has four vertical stands with height of 1500?2000 mm and support elements rigidly fixed to them in the form of bent bars with size of 150 mm with horizontal sections with length of 800?1200 mm. From horizontal sections of bars in the front part along the travel of the distributing device there are diverting inclined section with an angle of inclination to the longitudinal axis 45?55°, fixed on distributing pulp lines, which provides for self-tipping out of the distributing device during movement from the washed over section.EFFECT: lower clogging of a protective grate of a socket and higher mobility of a distributing device during relocation.6 dwg |
