Ngemuva kwenani elikhulu lamacala e-aquaculture, kuphetha ngokuthi ngokubeka phansi echibini, amanzi echibini ahlukaniswe nenhlabathi ukuze afeze inhloso yokuvimbela ukugeleza kwamanzi. Kuyisixazululo esifanelekile sokusebenzisa i-polyethylene HDPE geomembrane yamandla aphezulu njengolwelwesi oluphansi lwechibi ukuvimbela ukuvuza.
Ubuchwepheshe bokukhiqiza be-HDPE geomembrane buphule isimiso sezindwangu, futhi busebenzisa ulwazi lwesimanje lwesayensi. Indlela yayo yokucubungula iwukuhlela ngokungahleliwe imicu emifushane yendwangu noma imicu ukuze yakhe isakhiwo se-fiber mesh.
Ngesikhathi sokubekwa kwe-HDPE geomembrane, imibimbi yokwenziwa kufanele igwenywe ngangokunokwenzeka. Uma ubeka i-HDPE geomembrane, inani lokunwetshwa nelokufinyela elibangelwa ukushintsha kwezinga lokushisa kufanele ligcinwe ngokuya ngebanga lokushintsha kwezinga lokushisa lasendaweni kanye nezidingo zokusebenza ze-HDPE geomembrane. Ukwengeza, inani lokunwetshwa nokufinyezwa kwe-geomembrane kufanele ligcinwe ngokwendawo yesayithi kanye nezimo zokubeka i-geomembrane. Ukuzivumelanisa nokuhlaliswa okungalingani kwesisekelo.
Ukwakhiwa kokubeka nokushisela kwe-HDPE geomembrane kufanele kwenziwe lapho izinga lokushisa lingaphezu kuka-5℃, amandla omoya angaphansi kwezinga lesi-4, futhi imvula noma iqhwa lingekho. Inqubo yokwakha ye-hdpe geomembrane yenziwa ngohlelo olulandelayo: i-geomembrane laying → ukuqondanisa imithungo yokushisela → ukushisela → ukuhlola endaweni → ukulungisa → ukuhlola kabusha → ukugcwaliswa ngemuva. Ububanzi bokugqagqana bamalunga phakathi kolwelwesi akumele bube ngaphansi kwama-80 mm. Ngokuvamile, isiqondiso sokuhlelwa okuhlangene kufanele silingane nomugqa omkhulu wokuthambekela, okungukuthi, uhlelwe eceleni kokuqondisa komthambeko.
Ngemuva kokuthi i-hdpe geomembrane ibekwe, ukuhamba phezu kwe-membrane, amathuluzi okuthwala, njll. kufanele kuncishiswe. Izinto ezingabangela ukulimala kwe-hdpe geomembrane akufanele zibekwe ku-geomembrane noma zithwalwe ngenkathi uhamba ku-geomembrane ukugwema ukulimaza ulwelwesi lwe-hdpe. okubangela ukulimala ngengozi. Bonke abasebenzi endaweni yokwakha ulwelwesi lwe-HDPE abavunyelwe ukubhema, abavunyelwe ukugqoka izicathulo ezinezinzipho noma izicathulo ezinezinyawo eziqinile ezinezithende ukuze bahambe phezu kolwelwesi, futhi abavunyelwe ukuhlanganyela kunoma yiziphi izinto ezingase zilimaze i-anti-sepage membrane.
Ngemuva kokuthi i-hdpe geomembrane ibekwe, ngaphambi kokuba imbozwe ngesendlalelo sokuzivikela, isikhwama sesanti esingu-20-40kg kufanele sibekwe njalo ngo-2-5m emakhoneni olwelwesi ukuvimbela i-geomembrane ukuthi ingapheshulwa umoya. I-HDPE geomembrane anchorage kumele yakhiwe ngokuya ngomklamo. Ezindaweni ezinezindawo eziyinkimbinkimbi kuphrojekthi, uma iyunithi yokwakha iphakamisa ezinye izindlela zokunamathisela, kufanele ithole imvume yeyunithi yokuklama kanye neyunithi yokuqondisa ngaphambi kokuqhubeka.
Iqhaza le-geomembrane eyinhlanganisela kubunjiniyela bomgwaqo obunokuvikela ukuqina
1. Indima ye-geomembrane eyinhlanganisela kubunjiniyela bomgwaqo
1. Umphumela wokuzihlukanisa
Ukubeka i-geomembrane eyinhlanganisela phakathi kwezinto ezimbili ezihlukene, phakathi kwamadayamitha ahlukene okusanhlamvu wento efanayo, noma phakathi kwenhlabathi nesakhiwo esiphezulu kungayihlukanisa. Lapho indawo yomgwaqo ingaphansi kwemithwalo yangaphandle, nakuba impahla I-geomembrane eyinhlanganisela icindezelwa komunye nomunye ngaphansi kwamandla, kodwa ngenxa yokuthi i-geomembrane eyinhlanganisela ihlukaniswe phakathi, ayihlanganisi noma idonsa ndawonye, futhi ingagcina ingqikithi. isakhiwo kanye nomsebenzi wesisekelo somgwaqo. Isetshenziswa kakhulu kojantshi besitimela, emigwaqweni engaphansi kothelawayeka, kumaphrojekthi wedamu lomhlaba wamatshe, inhlabathi ethambile Ukucubungula okuyisisekelo kanye namanye amaphrojekthi.
2. Umphumela wokuvikela
I-geomembrane ehlanganisiwe ingadlala indima ekuhlakazeni ingcindezi. Lapho amandla angaphandle edluliselwa kusuka entweni eyodwa kuya kwenye, angakwazi ukubola ukucindezeleka futhi avimbele inhlabathi ukuba ingalinyazwa amandla angaphandle, ngaleyo ndlela ivikele izinto eziyisisekelo zomgwaqo. Umsebenzi wokuvikela we-geomembrane eyinhlanganisela ikakhulukazi ukuvikela indawo yokuxhumana yangaphakathi, okungukuthi, i-geomembrane eyinhlanganisela ibekwe phakathi kwezinto ezimbili endaweni yesisekelo somgwaqo. Lapho into eyodwa ingaphansi kokucindezeleka okugxilile, enye impahla ngeke yonakale.
3. Ukuqinisa umphumela
I-geomembrane eyinhlanganisela inamandla aphezulu okudonsa. Uma igqitshwe enhlabathini noma endaweni efanele esakhiweni esigandayiwe, ingasabalalisa ukucindezelwa kwenhlabathi noma isakhiwo somgandayo, idlulise ukuqina kwengcindezi, inciphise ukugudluka kwayo emaceleni, futhi ithuthukise ukuxhumana kwayo nomhlabathi noma umgwaqo. Ukungqubuzana phakathi kwezingqimba zesakhiwo kwandisa amandla enhlabathi noma ungqimba olugandayiwe lwesakhiwo kanye nenhlanganisela yezinto ze-geosynthetic, ngaleyo ndlela kuvimbele ukwakheka komhlabathi noma ungqimba lwesakhiwo somgwaqo, luvimbele noma lunciphise ukuminza okungalingani komhlabathi, futhi kuthuthukise ikhwalithi yomhlabathi. Noma ukuzinza kwesendlalelo sesakhiwo se-pavement kunomsebenzi wokuqinisa.
Nakuba ama-geomembranes ayinhlanganisela edlala izindima eziningi kumaphrojekthi omgwaqo, adlala izindima eziyinhloko nesesibili ezindaweni ezahlukene zephrojekthi. Isibonelo, uma ubeka phakathi kongqimba lwesisekelo setshe kanye nesisekelo somgwaqo onguthelawayeka, indima yokuhlukanisa ngokuvamile iyona eyinhloko, futhi ukuvikela nokuqiniswa kungokwesibili. Lapho wakha imigwaqo ezisekelweni ezibuthakathaka, umphumela wokuqinisa we-geomembrane oyinhlanganisela ungalawula umhlabathi.
