Mu mapulojekiti owongolera kutuluka kwa madzi—monga omwe akukhudza nyumba zapansi pa nthaka, nyanja zopangira, ndi malo otayira zinyalala—kodi vuto losatha la kutuluka kwa madzi lingathetsedwe bwanji moyenera komanso molimba? Monga wopanga wapadera pankhani ya geosynthetics, Shandong Hongyue Environmental Engineering Co., Ltd. (yomwe pano ikutchedwa "Hongyue Environmental") yagwiritsa ntchito ukadaulo wake waukulu mu Geosynthetic Clay Liners (GCLs) kuti ipange njira yomanga yolimba komanso yokhazikika mwasayansi. Kudzera m'magawo anayi ofunikira—"kukonzekera pansi pa nthaka, kukhazikitsa kwasayansi, kuphatikizika kolondola, ndi kudzaza madzi panthawi yake"—njira iyi imagwiritsa ntchito bwino ubwino wapadera wa GCL, makamaka kuthekera kwawo "kutumphuka akakumana ndi madzi ndikudzichiritsa okha," motero kukhazikitsa chotchinga chosalowa madzi cha mapulojekiti osiyanasiyana aukadaulo.
Gawo Loyamba: Kukonzekera Kolimba kwa Subgrade—Kukhazikitsa Maziko Osalala Ndi Okhazikika
Ubwino wa subgrade umatsimikizira mwachindunji momwe kukhazikitsa GCL kumagwirira ntchito. Gulu laukadaulo la Hongyue Environmental likugogomezera kuti pamwamba pa subgrade kuyenera kukonzedwa bwino musanamangidwe. Choyamba, subgrade iyenera kuchepetsedwa ndikulinganizidwa; makamaka, chiŵerengero cha flatness (chomwe chimatanthauzidwa ngati chiŵerengero cha kuya kwakukulu kwa kutsika kulikonse mpaka m'mimba mwake wocheperako) sichiyenera kupitirira 1:6, ndipo kusintha konse kuyenera kuchitika pang'onopang'ono, kuletsa mwamphamvu kupezeka kwa zinthu zakuthwa monga ngodya zakumanja. Chachiwiri, pamwamba pa subgrade kuyenera kusungidwa koyera, ndikuchotsa bwino zinyalala zonse zakuthwa—kuphatikizapo mizu ya udzu, miyala yayikulu kuposa 10 mm m'mimba mwake, ndi zidutswa za njerwa—kuti nsalu yakunja yolukidwa ya GCL isabowoledwe panthawi yoyika. Kuphatikiza apo, ngakhale GCL zitha kuyikidwa pa subgrade yonyowa, kusonkhanitsa madzi oyima pamwamba ndikoletsedwa kwambiri; nthawi zina pamene madzi oyenda osalamulirika akumana, njira zosinthira kwakanthawi ziyenera kukhazikitsidwa pasadakhale kuti zitsimikizire kuti malo ogwirira ntchito akukhalabe bwino.
Gawo Lachiwiri: Kukhazikitsa Kokhazikika ndi Kukhazikika—Kuonetsetsa Kuti Zikugwirizana Molimba Komanso Motetezeka
Panthawi yokhazikitsa, Hongyue Environmental imalimbikitsa kudula bwino ma GCL molingana ndi kukula kwa polojekitiyi; ma liners amatha kuyikidwa mopingasa kapena mopingasa. Panthawi yomanga, GCL imatambasulidwa mopingasa pa subgrade yokonzedwa, nthawi zambiri imayikidwa ndi wosanjikiza wa nsalu yolukidwa pansi ndipo wosanjikiza wa geotextile wosalukidwa umayang'ana mmwamba. Kuti muwonetsetse kuti GCL ndi subgrade zikugwirizana kwambiri, ma pini apadera a nangula ndi ma washer ayenera kugwiritsidwa ntchito kuti azimangirira bwino; kuphatikiza apo, m'mphepete mwa liner muyenera kudzazidwa ndi matumba amchenga kuti mupewe kusuntha komwe kumachitika chifukwa cha mphepo. Akatswiri aukadaulo akugogomezera kuti kusamala kwambiri kuyenera kuchitika panthawi yokhazikitsa. Ndikoletsedwa kwambiri kuti makina olemera aziyendetsa mwachindunji pamwamba pa bulangeti. Ogwira ntchito oyenda pa nsaluyo ayenera kuvala nsapato zathyathyathya kuti aletse zinthu zakuthwa kuti zisaboole nembanemba yamkati (ngati pali bulangeti losalowa madzi lopangidwa ndi membrane) kapena kuwononga wosanjikiza wakunja wa geotextile, zomwe zingasokoneze kufalikira kofanana kwa bentonite.
Gawo 3: Kuchiza Mogwirizana Mosamala—Kupanga Chigawo Chosatha Kupyola
Kukonza ma connection ndi chinthu chofunikira kwambiri chomwe chimatsimikizira kupambana kapena kulephera kwa dongosolo lonse losalowa madzi. Mafotokozedwe a kapangidwe ka Hongyue Environmental amalamula kuti m'lifupi mwa mabulangete osalowa madzi pafupi ndi mabulangete ayenera kusungidwa osachepera 25 cm mpaka 30 cm. M'dera lolumikizana, ufa wapadera wa bentonite wouma (kapena bentonite phala)—woperekedwa ndi kampani—uyenera kugwiritsidwa ntchito mofanana. Mlingo wogwiritsidwa ntchito nthawi zambiri umayendetsedwa pa 0.4 kg/m² kuti zitsimikizire kuti, pamene madzi alowa, cholumikiziracho chimapanga wosanjikiza wosalowa madzi wopitilira, wokhuthala, komanso wofanana ndi gel. Kuti mutseke kwambiri ma connection, kugwiritsa ntchito ufawo kumatha kuwonjezeredwa ndi tepi yapadera yosalowa madzi, kuonetsetsa kuti chilichonse chili bwino komanso chopanda chopingasa komanso chosalowa madzi.
Gawo 4: Kudzaza Zinthu Pa Nthawi Yake—Kupereka Chitetezo Cha Nthawi Yaitali
Mabulangeti osalowa madzi akayikidwa, njira yomangira kapena kudzaza mabulangeti iyenera kuyamba mwachangu momwe ingathere. Izi zimaletsa mabulangeti kuti asaume ndi kutaya mphamvu zawo chifukwa cha kuwonetsedwa kwa mpweya kwa nthawi yayitali, kapena kutupa msanga ngati mvula yagwa. Hongyue Environmental imayang'ana kwambiri zofunikira pa nthaka yodzaza mabulangeti: nthaka iyenera kutetezedwa kuti isachotse zinthu zolimba—monga miyala kapena zidutswa za njerwa—zokhala ndi tinthu tating'onoting'ono toposa 10 mm. Pomanga, nthaka yoyera kapena mchenga wabwino uyenera kugwiritsidwa ntchito podzaza mabulangeti ndi kukanikiza; makulidwe a gawo lililonse ayenera kulamulidwa mkati mwa 30 cm mpaka 50 cm, ndipo kuchuluka kwa kukanikiza kuyenera kufika osachepera 85%. Njirayi sikuti imateteza mabulangeti osalowa madzi ku kuwonongeka kwa makina akunja komanso imagwiritsanso ntchito kupsinjika komwe kumachitika ndi nthaka kuti iwonjezere kukhazikika kwa gawo losalowa madzi.
Pogwiritsa ntchito njira yokhazikika iyi ya "Njira Yomanga Yotsatira Njira Zinayi", mabulangeti osalowa madzi a Shandong Hongyue Environmental amatha kuwonetsa bwino ubwino wawo waukulu: kukana kwambiri kupsinjika kwa hydrostatic (kupitirira 1.0 MPa), mphamvu zodzichiritsa zokha (zokhoza kukonza ming'alu mpaka 2 mm kukula), komanso kukana kukalamba bwino komanso zinthu zosawononga chilengedwe. Kuyambira kupanga zinthu mpaka malangizo aukadaulo pamalopo, Hongyue Environmental Protection yadzipereka kwambiri kupatsa makasitomala njira zophatikizira zoletsa kulowa kwa madzi, kugwiritsa ntchito ukatswiri waluso komanso njira zokhwima kuti atsimikizire kuti ntchito iliyonse imakhalabe yolimba.
