Ukoresheje polyethylene yuzuye cyane nkibikoresho fatizo, imbavu zisohoka binyuze mumutwe wimashini idasanzwe, kandi imbavu eshatu zitondekanijwe mumwanya runaka nu mfuruka kugirango habeho imiterere-yimiterere yimiterere itatu hamwe numuyoboro wamazi.Urubavu rwo hagati rufite ubukana bwinshi kandi rukora umuyoboro wurukiramende.Ibice bitatu byimbavu zigize umuyoboro wamazi ufite imbaraga zihagaritse kandi zitambitse kandi zifite imbaraga zo kwikuramo.Umuyoboro wamazi wakozwe hagati yinzego eshatu zimbavu ntabwo byoroshye guhinduka munsi yumutwaro uremereye, ushobora kubuza geotextile kwinjizwa mumyanya ya geonet kandi bigatuma amazi atemba neza., Umuyoboro wa geotechnical-imiyoboro itatu-imiyoboro ifite imbaraga-nyinshi kandi ziyobora cyane ukurikije intego.
Ibicuruzwa byihariye
Uburebure bwa mesh: 5mm ~ 8mm;ubugari 2 ~ 4m, uburebure ukurikije ibyo ukoresha asabwa.
Ibiranga
1. Amazi akomeye (ahwanye na metero imwe yuburebure bwa kaburimbo).
2. Imbaraga zikomeye.
3. Mugabanye amahirwe ya geotextile yashyizwe muri mesh ya mesh kandi ukomeze amazi maremare.
4. Umwanya muremure wihanganira umutwaro mwinshi (urashobora kwihanganira umutwaro wo kwikuramo hafi 3000Ka).
5. Kurwanya ruswa, aside na alkali birwanya, igihe kirekire cyo gukora.
6. Kubaka biroroshye, igihe cyo kubaka kiragabanuka, kandi ikiguzi kiragabanuka.
Imikorere nyamukuru yo gusaba
1. Irashyirwa hagati yumusingi na sub-base kugirango ikure amazi yegeranijwe hagati yumusingi na sub-base, uhagarike amazi ya capillary kandi uyihuze neza muri sisitemu yo kuvoma.Iyi miterere ihita igabanya inzira yo gutemba yumusingi, igihe cyo kuvoma kiragabanuka cyane, kandi umubare wibikoresho byatoranijwe byatoranijwe urashobora kugabanuka (nukuvuga, ibikoresho bifite amande menshi kandi byoroshye bishobora gukoreshwa).Ongera ubuzima bwumuhanda.
2. Gushyira imiyoboro itatu-igizwe nurusobe rwamazi kuri sub-base birashobora kubuza ibintu byiza bya sub-base kwinjira mukibanza (ni ukuvuga ko bigira uruhare mukwigunga).Igiteranyo fatizo cyibanze kizinjira mugice cyo hejuru cya geonet kurwego ntarengwa.Ifite kandi ubushobozi bwo kugabanya urujya n'uruza rw'urufatiro rusange, muri ubu buryo ikora nko gushimangira geogrid.Muri rusange, imbaraga zingana nuburemere bwurwego rwibice bitatu bigize imiyoboro yamazi iruta iyindi ya geogride ikoreshwa mugushimangira umusingi, kandi uku kubuza kuzamura ubushobozi bwinkunga ya fondasiyo.
3. Nyuma yumuhanda umaze gusaza no gucamo, amazi menshi yimvura azinjira mugice.Muri iki gihe, imiyoboro itatu-yuzuye igizwe numuyoboro ushyirwa munsi yumuhanda aho kuba umusingi wamazi.Imiyoboro itatu-yuzuye igizwe na mesh irashobora gukusanya ubuhehere mbere yuko yinjira muri fondasiyo / subbase.Byongeye kandi, impera yanyuma yibice bitatu bigize imiyoboro y'amazi irashobora kuzingirwa hamwe na firime kugirango irusheho kubuza ubushuhe kwinjira mumfatiro.Kuri sisitemu yo kumuhanda itajenjetse, iyi miterere ituma umuhanda ushushanywa hamwe na coefficient yo hejuru ya Cd.Iyindi nyungu yiyi miterere ni amahirwe yo guhuza hydrata imwe ya beto (ubushakashatsi ku rugero rwiyi nyungu burakomeje).Haba kumihanda ikaze cyangwa sisitemu yumuhanda yoroheje, iyi miterere irashobora kongera igihe cyumurimo wumuhanda.
4. Mu bihe by’ikirere cy’amajyaruguru, gushyiraho imiyoboro itatu igizwe n’amazi arashobora kugabanya ingaruka ziterwa nubukonje.Niba ubujyakuzimu bwimbitse, geonet irashobora gushyirwa kumwanya muto muri sub-base kugirango ikore nka capillary blockage.Birakenewe kandi kenshi kubisimbuza na granular subbase idakunda guhura nubukonje bukabije, ikagera kumuhengeri.Ubutaka bwinyuma bworoshe gukonjesha burashobora kwuzuzwa muburyo butatu bwo guhuza imiyoboro itatu kugeza umurongo wubutaka.Muri iki gihe, sisitemu irashobora guhuzwa numuyoboro wamazi kugirango ameza yamazi ari cyangwa munsi yubujyakuzimu.Ibi birashobora kugabanya iterambere rya kirisita itagabanije imitwaro yimodoka mugihe urubura rushonga mugihe cyizuba mukarere gakonje.
Igipimo cyo gusaba
Kuvoma imyanda, kuzamura umuhanda no gutembera kaburimbo, imiyoboro ya gari ya moshi, imiyoboro ya tunnel, imiyoboro yubutaka, kugumana imiyoboro yinyuma, ubusitani hamwe nubutaka bwa siporo.
Ikirangantego
1. Guhindura icyerekezo cyibikoresho bya geosintetike, uburebure bwumuzingi uburebure bwibintu biri munzira.
2. Urusobe rwamazi ya geotechnique rugomba guhuzwa na geonet yegeranye, kandi uruziga rwa geosintetike rugomba kuba hamwe.
3. Ibara ryera cyangwa umuhondo ryibiti bya pulasitike cyangwa polymer bihujwe nubunini bwa geomaterial ya Hongxiang yegeranye na geonet, bityo bigahuza umuzingo wibikoresho.Ongeraho umukandara buri metero 3 ukurikije uburebure bwumuzingo wibikoresho.
4. Gupfundikira imyenda no gupakira mu cyerekezo kimwe nicyerekezo cyo gutondekanya.Niba geotextile iri hagati yifatizo, shingiro na sub-base yashizweho, gusudira guhoraho, gusudira imigozi cyangwa kudoda bizakorwa kugirango bihimbwe
Igice cya geotextile kirashobora gukosorwa.Niba bidoda, gukoresha igipfundikizo cyangwa uburyo rusange bwo kudoda birasabwa kugera kuburebure bwibisabwa byibuze.
