Abstract

Fremgangsmåte og anordning for transportering av betong og lignende materiale Fremgangsmåte og anordning for transportering av sprøytebetong og pumpet betongblanding av stiv plastisk konsistens (12) i rørledninger (I, I,IV) hvorved et fluid injiseres mellom perforeringer (10) i rørledningen (1) som omslutter sprøytebetongen eller den pumpede betongblanding (12) som skal transporteres. Fluidet kan bestå av trykk- luft, skum eller væske. Friksjonen mellom det transport- erte materiale og rørledningsinnerveggen blir derved betydelig redusert. Fluidet kan ledes gjennom perforering- ene (10) gjennom en rørveggmidtkanal (2) mellom et ytter- rør (4) og et innerrør (1) eller et rør eller et system av sammenkoplete kamre (2A) med perforeringer (10) som er innleiret i spiralform i en enkeltveggs-rørledning (l og 4). Rørledningen kan dreies brått 180° med og mot urviser- retningen med avbrudd og pauser mellom dreiebevegelsene med henblikk på redusert vedheftning og bedre homogenitet av blandingen som passerer gjennom rørledningen.Method and apparatus for transporting concrete and similar material Method and apparatus for transporting concrete and pumped concrete mixture of rigid plastic consistency (12) in pipelines (I, I, IV), whereby a fluid is injected between perforations (10) in the pipeline (1) which encloses the spray concrete or pumped concrete mixture (12) to be transported. The fluid may consist of compressed air, foam or liquid. The friction between the transported material and the pipeline inner wall is thereby considerably reduced. The fluid can be passed through the perforations (10) through a pipe wall center channel (2) between an outer tube (4) and an inner tube (1) or a tube or system of interconnected chambers (2A) with perforations (10) embedded in helical form in a single-wall pipeline (1 and 4). The pipeline can be rotated abruptly 180 ° clockwise and counterclockwise with interruptions and pauses between the pivotal movements for reduced adhesion and better homogeneity of the mixture passing through the pipeline.
