    摘要: Ce dispositif (6) est disposé en dessous de la trémie d'alimentation (4) d'une installation de projection et sert à alimenter la lance.
    Il comporte :

    un conduit de raccordement souple (9) qui prend appui contre une surface fixe et relie la sortie de la trémie (4) à l'entrée du conduit (2) amenant le mélange à la lance ;
    un ensemble mobile déplacé dans la direction d'évacuation du produit et qui est muni de protubérances (20,21) écrasant le tube (9) de façon étanche, afin que l'air contenu dans ledit tube (9) soit chassé par l'avant et crée une aspiration à l'arrière ;
    un élément de compression (22), disposé en aval de la trémie d'alimentation (4) et permettant, lorsque l'ensemble mobile se déplace et libère l'écrasement du tube (9), d'éviter le refoulement vers la trémie (4).

    摘要: An apparatus for manufacturing concrete columns, having a concrete-gunning unit (1) and a column-grinding unit (2) , the gunning unit having a gun (4) moving along a vertical boom (3) and a grinding disc (5), by means of which a concrete column is manufactured by gunning a concrete mix against a specific blank rotating about its axis (6), whereafter the hardened column is transferred to the grinding unit (2), where the surface of the concrete column is ground and polished by means of a second grinding device (8), moving along a vertical boom (7). Both the gunning unit and the grinding unit have tilting devices (9, 10) by means of which the vertical booms (3, 7) can be tilted relative to the axis (11) of the concrete column so that conical columns are produced.

    摘要: A method of dry shotcreting in which a dry cementitious composition (1) is combined with a mixture of water and silica fume at a spray nozzle (5). A silica fume composition is added to the water to form a slurry (9) of silica fume and water, and a mixture of curing accelerator and water (12) is added to the slurry of silica fume and water. The resulting slurry (8) and the dry composition (2) are combined at the spray nozzle (5).

    摘要: The invention concerns a method for producing a concrete pillar, said method being based on the shotcreting of an appropriately shaped frame structure of the concrete pillar with concrete, and said frame structure is simultaneously rotated on a rotating shaft (2) attached to the frame structure while being shotcreted with concrete, and said shotcreted concrete surface is shaped after shotcreting with the help of, e.g., a collar (4) having a desired shape. The concrete pillar is allowed to harden while being attached to the rotating shaft (2), and after hardening, the surface of the concrete pillar is ground with a grinding apparatus (5), and the concrete pillar is rotated on its rotating shaft either in the same rotating equipment in which the concrete pillars are shotcreted, or alternatively, in a separate grinding apparatus.
