DEVICE FOR LINING OF UNDERGROUND STRUCTURE CAST IN SITU Russian patent published in 2000 - IPC

Abstract RU 2154736 C1

FIELD: underground construction; applicable in construction of tunnels and other underground structures. SUBSTANCE: device has concrete-delivery pipeline, forms with opening for supply of concrete mix, mechanism for closing of opening in the form of wicket, gate secured to axle and made in the form of bent branch pipe whose external surface from the side of opening is flat and internal surface corresponds to curvature of concrete-delivery pipeline in zone of concrete mix supply. Device also has pipeline located under frame opening. Pipeline end on the side of concrete-delivery pipeline is located in branch pipe with wicket gate in opened position. Cross-section of branch pipe opening corresponds to that of openings of concrete-delivery pipeline and said pipeline. Branch pipe has brackets rigidly attached to concrete-delivery pipeline and said pipeline. Secured to one of them is drive member whose movable part is secured to turning part of wicket gate. Drive member may be made in the form of hydraulic cylinder. EFFECT: higher convenience of device operation, increased productivity, improved quality of lining. 2 cl, 4 dwg
