Allen sealer Concreting molds lining DEVELOPMENTS

摘要

The claimed technical solution relates to the mining, in particular in underground development with the construction of the concrete lining. The claimed utility model may be used in coal, ore mining and construction of tunnels of various purposes. Of the end sealer formwork for concrete lining excavations, comprises a metal rim with an elastic inflatable rubber bladder on the outer surface of which has a flexible strip-laying with apron inner portion of the outer side of the flange has a curved surface, and between the surface of the inflatable rubber chamber and the interior of the outer side flange is hard apron. Technical result of utility model is to improve the efficiency of the mechanical dock ( "end face formwork"), quality assurance and durability of concrete lining operation is being built of concrete lining of mine workings.
