Ni ibihe bice bigize urusobe rw'amazi rugizwe n'ibice?

Inzitiramibu zikoreshwa mu gucukura imyanda mu buryo bwa "composite" ni ibikoresho bikunze gukoreshwa mu gucukura imyanda, mu nzira zo ku muhanda, mu nkuta z'imbere mu miyoboro y'amazi n'indi mishinga. None se, ni ibihe bice bigize inzitiramibu zikoreshwa mu gucukura imyanda mu buryo bwa "composite"?

Urushundura rw’amazi rugizwe n’inkingi ya pulasitiki ifite imiterere itatu hamwe n’icyuma gifunganye gifite impande ebyiri gishobora kwinjiramo amazi. Uku guhuza ntabwo guha gusa urushundura rw’amazi rufite ubushobozi bwo gusohora amazi, ahubwo kunatuma rugira ibyiza byo gukomera cyane, kudatwarwa n’ingufu no kumara igihe kirekire.

1. Ishingiro ry'umuyoboro wa pulasitiki ni igice cy'ingenzi cy'urushundura rw'amazi rwakozwe muri pulasitiki. Rukozwe muri polyethylene ifite ubucucike bwinshi (HDPE) kandi rutunganywa hakoreshejwe uburyo bwihariye bwo gushushanya. Uru rushundura rufite imiterere yihariye y'urwego rutatu. Impande zo hagati zirakomeye kandi zitondetse neza kugira ngo zikore umuyoboro w'amazi; imbavu zitondetse hejuru no hasi zikora inkingi yo kurinda ko umuyoboro wa geotextile winjizwa mu muyoboro w'amazi. Nubwo haba hari imizigo myinshi cyane, urushundura rw'umuyoboro wa pulasitiki rushobora kugumana imikorere myiza yo gusohora amazi. Ingufu zo gukurura no gukandagira z'urushundura rw'umuyoboro wa pulasitiki zirakomeye cyane, ibyo bikaba bishobora kwemeza ko urushundura rw'amazi rwakozwe muri pulasitiki ruhamye kandi rukarangwa n'ukuri mu gihe kirekire.

2. Geotextile inyuramo amazi ni ikindi kintu cy'ingenzi mu rushundura rw'amazi ruvanze. Muri rusange ikoresha ibikoresho nk'igitambaro cya polyester filament, igitambaro cya polyester staple fibre cyangwa igitambaro cya polypropylene staple fibre. Akamaro ka geotextile ni ukuyungurura imyanda, gutuma igice cy'umuyoboro kigenda neza, no gusohora amazi ku gihe. Geotextile ishobora kandi gufatanywa neza n'igice cy'umuyoboro cya pulasitiki kugira ngo habeho imiterere y'umuyoboro w'amazi, ishobora kunoza imikorere y'umuyoboro w'amazi n'ubuzima bw'umuyoboro w'amazi uvanze.

3. Uretse ibice bibiri by'ingenzi byavuzwe haruguru, urushundura rw'amazi rushobora kandi guhindurwa hakurikijwe ibyo abakiriya bakeneye mu gihe cyo gukora. Urugero, igitambaro cya geotextile cyashyizwe ku mpande zombi gishobora kuba igitambaro cy'umunyururu, igitambaro kigufi cy'umunyururu, igitambaro cy'icyatsi kibisi cyangwa igitambaro cy'umukara. Ubu buryo bworoshye butuma urushundura rw'amazi ruhuza neza n'ibyo imishinga itandukanye ikeneye kandi rukanoza imikorere n'inyungu rusange z'umushinga.

Urushundura rw'amazi rushobora gukoreshwa mu bintu byinshi nko mu byobo byo guterera imyanda, inzira zo ku muhanda, no mu nkuta z'imbere mu miyoboro y'amazi. Ntirushobora gusa gusohora amazi yakusanyijwe hagati y'ifatizo n'inyuma y'ubutaka, gufunga amazi ya capillary, ahubwo runanongera ubushobozi bwo gushyigikira ifatizo no kongera igihe cyo gukora umuhanda. Byongeye kandi, rufite ibyiza byo kubaka byoroshye, igihe gito cyo kubaka no kugabanya ikiguzi.

Nkuko bigaragara muri ibi byavuzwe haruguru, urushundura rw’amazi rugizwe n’ibice bibiri: igice cy’imbere cya pulasitiki gifite imiterere itatu n’igice cy’imbere gishobora kwinjiramo gifite impande ebyiri. Kubwibyo, imikorere yacyo yo kuvoma ni myiza cyane kandi gishobora gukoreshwa mu mishinga minini.
