Ngokuthuthukiswa kwemigwaqo emikhulu emhlabeni, izinkinga eziningi ziye zadalulwa ngesikhathi sokusetshenziswa, njengokulimala komgwaqo kanye nokuhlaliswa kwemigwaqo. Lezi zinkinga zizothinta ukuphepha kanye nokunethezeka kokushayela, futhi zizophazamisa impilo yesevisi yemoto. I-Taishaninc geogrid shed iwuhlobo olusha lwe-geosynthetic material. Uma kuqhathaniswa nezinye izinto zokwakha, inokusebenza kwayo okuyingqayizivele nokusebenza ngempumelelo. Inamandla aphezulu, umthamo oqinile wokuthwala imithwalo, ukuqina okuqinile, ukwakhiwa okulula kanye nempilo ende yesevisi. Ngokusebenzisa i-polyester geogrid reinforcement ukuze kuthuthukiswe umthamo wokuthwala we-subgrade ethambile yomhlabathi nokunciphisa ukuhlala kwayo ngemva kokwakhiwa, ubuchwepheshe bokwakha be-polyester geogrid reinforced subgrade kwaxoxwa ngokuhlelekile, futhi kwafinyezwa izinyathelo zobuchwepheshe zokulawula ukwakhiwa okunokwenzeka. Imiphumela yokuqaliswa kwale phrojekthi ibonisa ukuthi i-polyester geogrid inezinzuzo zamandla aphezulu, umthamo oqinile wokuthwala umthwalo, ukuqina okuqinile, ukwakhiwa okulula, nokuphila isikhathi eside, futhi ingasetshenziswa kumaphrojekthi afanayo.

I-Taishaninc polyester geogrid i-reinforced subgrade pavement isetshenziswa kakhulu ekwakhiweni komgwaqo omkhulu wase-Europe. Imisebenzi eyinhloko ye-polyester geogrid esetshenziswa emigwaqweni emikhulu ihlanganisa ukuqinisa, ukuvikela, ukuhlunga, ukukhipha amanzi kanye nokuhlukaniswa. I-Polyester geogrid ifaneleka kakhulu ukulungiswa komgwaqo onguthelawayeka othambile we-subgrade, ukuqiniswa kwe-subgrade, ukugcwaliswa kweplatifomu, ukuhlanganisa imigwaqo emisha nemidala, ukusefa nokukhipha amanzi, njll.

(1) Ngaphambi kokwakhiwa okusemthethweni, izinto zokwakha ze-polyester geogrid zidinga ukukhethwa ngokuvumelana nezidingo zokuklama. I-polyester geogrid esetshenziswe kule phrojekthi yelulwe ngendlela engaqondile i-polyethylene polyester geogrid ene-high-density polyester geogrid. Ngaphambi kokubeka, i-polyester geogrid kufanele ihlolwe. Uma kutholakala imibimbi, kufanele iqondiswe ngomshini noma ngesandla.

I-2) I-filler esetshenziswe kuphrojekthi kufanele ihlangabezane nezidingo ezilandelayo: ukuvunyelwa kwamanzi kokugcwalisa kufanele kube kuhle, futhi i-angle yayo yangaphakathi ye-friction kufanele ilawulwe ngaphakathi kwe-30 °. Uma kunesidingo, ukuhlolwa kwe-geotechnical esizeni kufanele kwenziwe ku-filler; kukhona imiphetho ebukhali namakhona ku-filler. Okuqukethwe kwenhlabathi kufanele kulawulwe ku-15% yenani eliphelele lempahla ukugwema ukulimala kwe-polyester geogrid okubangelwa imiphetho ebukhali; ubukhulu bezinhlayiya zezinhlayiya zenhlabathi ku-filler kufanele zilawulwe ngaphakathi kwe-100mm.

Lapho kumbiwa nokwakhiwa kombhede wesisekelo, udinga kuphela ukulandela ubuchwepheshe bokwakha obujwayelekile bombhede wesisekelo. Ayikho enye incazelo kulesi sihloko. Kodwa-ke, ngesikhathi sokwakhiwa kombhede wesisekelo, ukunakwa okukhethekile kufanele kukhokhwe ukuze kuqinisekiswe ukuthi ukumbiwa kombhede wesisekelo kuhlangabezana nomklamo. kanye nezidingo zokwakha. Ngesikhathi esifanayo, izinyathelo zokuvimbela amanzi kanye nokukhipha amanzi kufanele zithathwe emgodini wesisekelo ukuze kuncishiswe imiphumela emibi yamanzi. Lapho ukumbiwa kombhede wesisekelo kulinganiswa futhi kuhlanganiswe, umcamelo wetshe ungabekwa ngemva kokuhlolwa ukuze kuqinisekiswe ukuthi ufanelekile. Ubukhulu bayo kufanele bulawuleke ku-30cm. Ngemuva kokubeka umcamelo wegravel, kufanele ulinganiswe ngesikhathi, futhi umehluko wobude obuvumelekile wendawo endaweni yomcamelo kufanele ulawulwe ku-10cm. Ngemva kokubekwa kwe-gravel cushion, ukubekwa kwe-polyester geogrid kungaqala. Okokuqala, usike i-grating eqinisiwe yomhlabathi ngokuvumelana nezidingo zokuklama, bese uyibeka ngokuvumelana nezidingo zemidwebo yokuklama. Ubude obuthile begridi kufanele bubekelwe ngaphandle kwendawo eyehlelayo ukuze kupakishwe emuva. Phakathi nenqubo yokubeka i-polyester geogrid, ukunakwa okukhethekile kufanele kukhokhwe eqinisweni lokuthi isiqondiso sokucindezeleka se-polyester geogrid kufanele sibekwe eceleni kwe-axis longitudinal. Ama-polyester geogrid akufanele abe namajoyinti eduze kwesiqondiso esikhulu sokucindezeleka.

Lapho ubeka i-polyester geogrid, indawo, ubude kanye nesiqondiso esisethwe emidwebeni yokuklama kufanele ilandelwe. Ububanzi bokugqagqana emzileni kufanele bulawuleke ku-10cm. Ngemva kokuqedwa kokubeka, izipikili ezimise okwe-U zisetshenziselwa ukusekela i-polyester geogrid. Ukuhlukana kwezinzipho ezimise okwe-U kufanele kugcinwe kude. Ukulungiswa kwezipikili ezimise u-U kungavimbela i-polyester geogrid ekushintsheni ngesikhathi sokugcwalisa ukwakhiwa. Amajoyinti e-polyester geogrid ahambisana nezikhombisi-ndlela ezingezona eziyinhloko zengcindezi aboshwe ngezintambo zenayiloni, ngaphandle kwesidingo sokugqagqana. Isikhala phakathi kokubopha kufanele silawulwe ku-lm.

Ngemuva kokuthi i-polyester geogrid ibekwe njengoba kudingeka, ukwakhiwa kwe-backfill kufanele kwenziwe ngesikhathi. Isikhathi sokuchayeka se-polyester geogrid akumele sibe side kakhulu ukuvimbela izinkinga zokuguga ezibangelwa ukuchayeka elangeni. Ngesikhathi sokwakhiwa kwe-backfilling, usayizi wezinhlayiyana zokugcwalisa okusetshenzisiwe akufanele udlule u-1/2 wesendlalelo sokugoqa. Ngesikhathi sokwakhiwa kokugcwalisa, iziphetho ezimbili ze-polyester geogrid kufanele ziqale zigcwaliswe futhi isiteji se-longitudinal noma umzila wethrafikhi kufanele wakheke. , bese ububanzi bokugcwalisa emuva kufanele bunwetshwe ngokushintshana. Ngesikhathi sokwakhiwa kwe-rebound ye-filler, ukuhamba kwezimoto akuvunyelwe ku-polyester geogrid eqediwe.

Ukulinganisa kokugcwalisa kungenziwa ngomshini noma ngesandla. Ngemuva kokwelashwa kokulinganisa, umehluko wobude bendawo endaweni kufanele ulawulwe ngaphakathi kwe-Scm. Lapho ukwakhiwa kwe-rolling kwenziwa, kufanele kwenziwe ngokulandelana kusukela kokubili kokuphela kuya phakathi. Izindlela zokwakha ezilandelanayo azivunyelwe. Ngesikhathi sokwakhiwa, i-roller yomgwaqo kufanele ishayele eceleni komugqa ukuze kugwenywe ukwenzeka kokushayela okuvundlile nokugingqika. Ngemuva kokuthi ukwakhiwa kokugoqa kwesendlalelo ngasinye sokugcwalisa kuqediwe, ukuminyana kwayo kufanele kuhlolwe ukuze kuqinisekiswe ukuthi kuhlangabezana nezidingo ngaphambi kokuqhubeka nokwakhiwa kwesendlalelo esilandelayo sokugcwalisa. I-compact degree degree yokugcwalisa ilawulwa ngokuhambisana nezidingo ezijwayelekile zokubopha.
