Amakuru

Nyuma y’imibare myinshi y’ubuhinzi bw’amafi, hanzuwe ko mu kuyishyira munsi y’icyuzi, amazi yo mu cyuzi yitaruye ubutaka kugira ngo agere ku ntego yo gukumira amazi. Ni igisubizo cyiza cyo gukoresha imbaraga nyinshi polyethylene HDPE geomembrane nkumurongo wanyuma wicyuzi kugirango wirinde kumeneka.

Ubuhanga bwo gukora bwa HDPE geomembrane bwarenze ku ihame ryimyenda, kandi bukoresha ubumenyi bwa siyansi bugezweho. Uburyo bwayo bwo kuyitunganya ni ugutondekanya imyenda ya fibre ngufi cyangwa filaments kugirango ibe fibre mesh.

Mugihe cyo gushyira HDPE geomembrane, imyunyu ngugu igomba kwirindwa bishoboka. Iyo ushyizeho geomembrane ya HDPE, kwaguka no kugabanuka biterwa n’imihindagurikire y’ubushyuhe bigomba kubikwa ukurikije urugero rw’imihindagurikire y’ubushyuhe bwaho hamwe n’ibisabwa na geomembrane ya HDPE. Byongeye kandi, kwaguka no kugabanuka kwa geomembrane bigomba kubikwa ukurikije imiterere yikibanza hamwe na geomembrane. Guhuza no gutuza kuringaniza umusingi.

Kubaka no gusudira bya HDPE geomembrane bigomba gukorwa mugihe ubushyuhe buri hejuru ya 5 ℃, ingufu z'umuyaga ziri munsi yurwego rwa 4, kandi nta mvura cyangwa shelegi. Gahunda yo kubaka hdpe geomembrane ikorwa muburyo bukurikira: gushira geomembrane → guhuza ingendo zo gusudira → gusudira → kugenzura aho → gusana → kongera kugenzura → gusubira inyuma. Ubugari bwuzuye bwuburinganire hagati yibibondo ntibushobora kuba munsi ya 80 mm. Mubisanzwe, guhuriza hamwe icyerekezo bigomba kuba bingana numurongo ntarengwa uhanamye, ni ukuvuga, utunganijwe werekeza kumurongo.

Hdpe geomembrane imaze gushyirwaho, kugenda hejuru ya membrane, gutwara ibikoresho, nibindi bigomba kugabanywa. Ibintu bishobora guteza ingaruka mbi kuri hdpe geomembrane ntibigomba gushyirwa kuri geomembrane cyangwa ngo bitwarwe mugihe ugenda kuri geomembrane kugirango wirinde kwangiza membrane ya hdpe. guteza impanuka. Abakozi bose bari ahazubakwa HDPE membrane ntibemerewe kunywa itabi, ntibemerewe kwambara inkweto zifite imisumari cyangwa inkweto ndende zifite inkweto zikomeye kugirango bagende hejuru ya membrane, kandi ntibemerewe kwishora mubikorwa ibyo aribyo byose bishobora kwangiza anti-seepage membrane.

Hdpe geomembrane imaze gushyirwaho, mbere yuko itwikirwa nigice kirinda, hagomba gushyirwaho umufuka wumucanga wa 20-40 kg buri 2-5m kumpande za membrane kugirango wirinde geomembrane guhuhwa numuyaga. HDPE geomembrane anchorage igomba kubakwa ukurikije igishushanyo. Ahantu hamwe nubutaka bugoye mumushinga, niba ishami ryubwubatsi risaba ubundi buryo bwo gufata ibyuma, bigomba kwemererwa nubushakashatsi hamwe nishami rishinzwe kugenzura mbere yo gukomeza.

Uruhare rwa geomembrane ikomatanya mubuhanga bwumuhanda hamwe no kurinda igihe kirekire
1. Uruhare rwa geomembrane ikomatanya mubuhanga bwumuhanda

1. Ingaruka zo kwigunga

Gushyira geomembrane ikomatanya hagati yibikoresho bibiri bitandukanye, hagati ya diametre zitandukanye zintete yibintu bimwe, cyangwa hagati yubutaka nubutaka bushobora kubigunga. Iyo ubuso bwumuhanda bugomba gukorerwa imizigo yo hanze, nubwo ibikoresho bigize geomembrane ikomatanyirijwe hamwe ku mbaraga, ariko kubera ko geomembrane ikomatanya itandukanijwe hagati, ntabwo ivanga cyangwa ngo itwarwe hamwe, kandi irashobora gukomeza muri rusange imiterere n'imikorere y'ibikoresho fatizo byumuhanda. Ikoreshwa cyane muri gari ya moshi, kuzamura umuhanda, imishinga y'urugomero rw'ubutaka, ubutaka bworoshye Gutunganya Shingiro nibindi bikorwa.

2. Ingaruka zo gukingira

Gukomatanya geomembrane irashobora kugira uruhare mukwirakwiza impagarara. Iyo imbaraga zo hanze zandujwe mubintu bikajya mubindi, birashobora kugabanya imihangayiko no kubuza ubutaka kwangizwa nimbaraga zituruka hanze, bityo bikarinda ibikoresho fatizo byumuhanda. Imikorere yo gukingira geomembrane igizwe cyane cyane kurinda imbere yimbere yimbere, ni ukuvuga geomembrane ikomatanya ishyirwa hagati yibikoresho bibiri hejuru yumuhanda. Iyo ikintu kimwe gihangayikishijwe cyane, ibindi bikoresho ntabwo byangiritse.

3. Gushimangira ingaruka

Imiterere ya geomembrane ifite imbaraga zingana. Iyo ishyinguwe mu butaka cyangwa ahantu hakwiye mu miterere ya kaburimbo, irashobora gukwirakwiza imihangayiko yubutaka cyangwa imiterere ya kaburimbo, kwimura imihangayiko ikabije, kugabanya iyimurwa ryayo, no kongera isano nubutaka cyangwa umuhanda. Ubuvanganzo hagati yububiko bwibikoresho byubaka byongera imbaraga zubutaka cyangwa pavement yuburyo bwubatswe hamwe nibikoresho bya geosynetique, bityo bikabuza imiterere yubutaka cyangwa pavement yubatswe, bikabuza cyangwa bigabanya ubutaka butaringaniye bwubutaka, kandi bikazamura ubwiza bwubutaka. Cyangwa ituze rya pavement yuburyo bwa pavement ifite imikorere ishimangira.

Nubwo geomembrane igizwe ninshingano nyinshi mumishinga yo mumuhanda, ikina inshingano zibanze nizisumbuye zitandukanye mumishinga itandukanye. Kurugero, iyo ushyize hagati ya kaburimbo ya kaburimbo nishingiro ryumuhanda, uruhare rwo kwigunga muri rusange nirwo nyamukuru, kandi kurinda no gushimangira ni Byakabiri. Iyo wubatse imihanda ku rufatiro rudakomeye, ingaruka zishimangira geomembrane ikomatanya irashobora kugenzura ubutaka.
