Arrangement for supplying and disposal of underground working with multi-component resin

摘要

The arrangement comprises a filling station at which liquid A-component is filled in a large white barrel (1), and liquid B-component is filled in a large black barrel (2). Each barrel can contain about (200) litres of liquid. The barrels are transported to a feed pump (19) where the components are separately removed, dosed and conveyed by a feed pump. The empty barrels are then returned to the filling station. A secondary packaging (7,8) is provided for the barrels, with which a leakproof transport unit (9,10) is assembled. The barrels are reusable, and the feed pump has separate supply tanks (20,21) for liquid components. The supply tanks have draining devices (22,23) which valves (37,41) which are unmistakable from each other. The valves fit in barrel boltings of the transport units.
