I-Geogrid yepulasitiki
Incazelo emfushane:
- Yenziwe kakhulu ngezinto ze-polymer ezinama-molecule aphezulu njenge-polypropylene (PP) noma i-polyethylene (PE). Ngokubukeka, inesakhiwo esifana ne-grid. Lesi sakhiwo se-grid sakhiwa ngezinqubo ezithile zokukhiqiza. Ngokuvamile, izinto zokusetshenziswa ze-polymer kuqala zenziwa zibe yipuleti, bese kuthi ngezinqubo ezifana nokubhoboza nokwelula, i-geogrid ene-grid ejwayelekile igcine ibunjwe. Ukuma kwe-grid kungaba yisikwele, unxande, ukuma kwedayimane, njll. Usayizi we-grid kanye nobukhulu be-geogrid kuyahlukahluka ngokuya ngezidingo ezithile zobunjiniyela kanye nezindinganiso zokukhiqiza.

Izici Zokusebenza
1. Izakhiwo Zomshini
Inamandla okudonseka aphezulu. I-geogrid yepulasitiki enwetshiwe ngokulinganayo inamandla okudonseka avelele kakhulu ohlangothini lokunwebeka futhi ingamelana namandla amakhulu okudonseka ngaphandle kokuphuka. Isibonelo, amandla okudonseka kwamanye ama-geogrid anwetshiwe ngokulinganayo asezingeni eliphezulu angafinyelela ngaphezu kuka-100kN ngemitha, okwenza kube kuhle kakhulu ekuqiniseni izisekelo nokuvimbela ukufuduka kwenhlabathi eceleni.
I-geogrid yepulasitiki enwetshiwe ngokulinganayo inamandla okubopha alinganayo futhi ingasabalalisa ngempumelelo ukucindezeleka. Ingaba nomphumela wokuvimbela inhlabathi ngasikhathi sinye kuzo zombili izinkomba ezinde neziphambeneyo, ithuthukise ubuqotho kanye nokuqina kwesisindo senhlabathi.
2. Ukumelana Nokugqwala
Ngenxa yokuthi izingxenye zayo eziyinhloko ziyi-polymers njenge-polypropylene noma i-polyethylene, inokubekezelela okuhle amakhemikhali afana nama-acid nama-alkali. Kwezinye izindawo zomhlabathi ezine-asidi ephezulu noma i-alkalinity noma izindawo lapho izinto zamakhemikhali zingavuza khona, i-geogrid yepulasitiki ingagcina ukuzinza kwayo kokusebenza futhi ngeke yonakale ngenxa yokugqwala kwamakhemikhali, ngaleyo ndlela iqinisekise ukuzinza kwesikhathi eside kwephrojekthi.
3. Ukumelana Nokuguguleka
Ubuso bayo bubushelelezi, kodwa inokumelana okuthile nokuguguleka. Ngesikhathi senqubo yokwakha, noma ngabe iguguleka ezinhlayiyeni zomhlabathi kanye nemishini yokwakha, ngeke iguguleke kalula futhi ingaqinisekisa ukuthi ubuqotho besakhiwo kanye nokusebenza kwe-geogrid akuthinteki. Ngaphezu kwalokho, ingamelana nokukhuhla nokuguguleka kwezinhlayiya zomhlabathi ngesikhathi sokusetshenziswa isikhathi eside.
4. Ukusebenza Kokukhipha Amanzi
Isakhiwo esifana ne-mesh se-geogrid yepulasitiki siwusizo ekukhipheni amanzi. Kweminye imisebenzi yokwelapha isisekelo edinga ukukhishwa kwamanzi, singasebenza njengomsele wokukhipha amanzi, sivumele amanzi angaphansi komhlaba noma amanzi angaphezulu ukuthi aphume ngemingxunya ye-geogrid, sinciphise ingcindezi yamanzi embotsheni enhlabathini futhi sandise amandla okusika enhlabathini.
Izindawo Zokufaka Isicelo
1. Ubunjiniyela Bemigwaqo
Isetshenziswa kabanzi ekuqiniseni imigwaqo emikhulu, izitimela, kanye neminye imigwaqo. Ukubeka i-geogrid yepulasitiki phansi kwe-subgrade kungathuthukisa amandla okuthwala kwe-subgrade futhi kunciphise ukuhlala okungalingani kwe-subgrade. Ikakhulukazi esigabeni se-subgrade esithambile, ingahlakaza ngempumelelo umthwalo wemoto odluliselwa ebusweni bomgwaqo, ivimbele ukuphuma kwenhlabathi engaphansi kwe-subgrade, futhi ithuthukise impilo yesevisi kanye nenduduzo yokushayela yomgwaqo.
2. Ubunjiniyela Bokuvikela Ukwehla
Isetshenziselwa ukuqinisa nokuvikela amagquma. Ngokufaka i-geogrid enhlabathini ethambekele, ukuzinza kwenhlabathi okulwa nokushelela kungathuthukiswa. Amandla okungqubuzana phakathi kwayo nenhlabathi angavimbela inhlabathi ukuthi ishelele phansi ebusweni bethambekele, futhi ingadlulisela umthwalo ongaphezulu kwethambekele ngaphakathi komzimba wethambekele, okwenza ithambekele lihlale lizinzile lapho lithintwa yizici zangaphandle ezifana nokukhuhla amanzi kanye nokuzamazama komhlaba.
3. Ubunjiniyela Bokugcina Udonga
Ukubeka i-geogrid yepulasitiki endaweni yokugcina ngemuva kodonga lokugcina kunganciphisa ingcindezi eseceleni kwe-backfill odongeni lokugcina. Ukusebenzisana phakathi kwe-geogrid kanye ne-backfill kwenza i-backfill yakheke yonke, futhi ingxenye yengcindezi eseceleni ye-backfill iguqulwa ibe amandla okudonsa e-geogrid, ngaleyo ndlela kunciphisa umthwalo othwalwa udonga lokugcina futhi kwehlise usayizi wesakhiwo kanye nezindleko zodonga lokugcina.
