THE CLOGGING OF DRAIN PIPES - A COMPARATIVE LABORATORY STUDY
DRAENERINGSROERS IGENSAETTNING - EN JAEMFOERANDE LABORATORIESTUDIE
The aim of this examination was to investigate the draining capacity and the clogging of different kinds of drainage pipes in different aggregate materials. Altogether nine pipes were investigated, among them four made of PVC, one of PEH, two of concrete, one of porous concrete and one of brick. Two different aggregate materials were used, partly crushed stone and partly unsorted natural gravel. The investigation was carried out in nine phases. During the first three phases only water was supplied, during the phase 4 filler material was used, during the phases 5 and 6 stone powder and during the phases 7-9 aluminium phosphate. Total operating time was 58 days. Except flow measurements, analyses were carried out of iron and turbidity. The results show that (a) the selection of aggregate material is much more important than the selection of pipe, (b) the differences in clogging between the different pipes were small and no pipe clogged considerably faster than another, (C) the drainage pipes of brick, concrete and porous concrete had at the beginning a lower draining efficiency than the other pipes but showed slower clogging and have a higher draining capacity, (D) the drainage pipes of plastic and the perforated farmpipe of concrete showed similar cloggings in the natural gravel, (e) the drainage pipe of pvc with a fibre-cloth clogged faster than the other in the crushed stone, but just as fast as the other plastic pipes in the natural gravel.
