Mortar pumping method for backfilling or jointing additional replacement of manual application, involves pumping of mortar by compressed air and vibration and brought to backfilling or jointing location, without touching product mechanism

摘要

The method involves pumping of a mortar that is from a pressure resistant container, by compressed air and vibration and brought to the backfilling or jointing location, without touching the product mechanism. The mortar is activated by outside action of vibration in the frequency range from 5 to 150 hertz with a centrifugal force within the range 5 to 20 Newton per kilogram of mortar. The oscillations and the vibrations are linear, i.e. rapping. The load pressure lies on the mortar within the range of 1 to 3 bars. An independent claim is also included for an apparatus for the execution of the method, which has a pressure resistant, two parts, and cylindrical container.
