Description
Перемещением плит 9 и 10 домкратами И и 12 вдоль и поперек тележки 1 и покачиванием водила 13 добиваютс того, чтобы рассто ние от сопла до бетонируемой поверхности по всему контуру выработки было в пределе, обеспечивающем оптимальный режим работы устройства дл нанесени набрызг-бетона. Затем включают устройство дл нанесени набрызг-бетона. Движуща с по щлангу 4 суха смесь проходит через гибкое колепо 8 и сопло 5, затвор етс водой и наноситс на породную поверхность.Moving the plates 9 and 10 with And and 12 jacks along and across the carriage 1 and rocking the carrier 13 ensures that the distance from the nozzle to the concreted surface along the entire production contour is within the limit ensuring the optimum mode of operation of the sprayed-concrete device. Then a spraying concrete device is included. The dry mixture moving along the hitch 4 passes through the flexible joint 8 and the nozzle 5, it is closed with water and applied to the rock surface.
В зависимости от скорости движени смеси и ее плотности, в гибком колене 8 по вл ютс реактивные усили разной величины, которые вызывают перемещение сопла 5 по отнощеиию к бетонируемой поверхности. Возвращение сопла 5 в блилснее по отнощению к поверхности положение осуществл етс торсионным валом 7 и рычагами 6.Depending on the speed of the mixture and its density, reactive forces of various sizes appear in the flexible elbow 8, which cause the movement of the nozzle 5 relative to the concrete surface. The return of the nozzle 5 to the position relative to the surface is carried out by the torsion shaft 7 and the levers 6.
