I-PP Biaxial Geogrid polypropylene geogrid yokuqinisa umgwaqo onguthelawayeka
Izici Zomkhiqizo
I-PP biaxial geogrid yenziwe nge-polymer ngokusebenzisa i-extrusion, ukwakheka kwepuleti, inqubo yokubhoboza bese kuba ukwelula okude nokuguquguqukayo.Izinto ezisetshenziswayo zinamandla amakhulu okuqina kuzo zombili isiqondiso se-longitudinal kanye nesiphambano, futhi lesi sakhiwo singanikeza amandla anamandla okuthwala kanye nokusabalalisa uhlelo oluhle lwamaketanga enhlabathini, olufanele ukuqiniswa kwendawo enkulu yesisekelo sokuzala unomphela.
Ekwenziweni kwe-PP biaxial geogrid, ama-polymers azohlelwa kabusha futhi aqondiswe kabusha kanye nenqubo yokushisisa nesandiso, eqinisa amandla okubopha phakathi kwamaketanga amangqamuzana futhi afeze injongo yokuthuthukisa amandla awo.Ubude bayo buyi-10% ~ 15% kuphela yepuleti lokuqala.Uma i-carbon black kanye nezinye izinto zokulwa nokuguga zengezwa ku-geogrid, ingenziwa ibe nokumelana okungcono ne-asidi, i-alkali, ukugqwala nokuguga.

Ukufakwa
(1) okokuqala, umugqa owehlelayo we-subgrade ukhululwa ngokunembile.Ukuze kuqinisekiswe ububanzi be-subgrade, uhlangothi ngalunye lunwetshwa ngo-0.5m.Ngemva kokulinganisa kwesisekelo senhlabathi, i-25T vibratory roller isetshenziselwa ukucindezela okumile kabili, futhi ukucindezela kokudlidliza okungu-50T kusetshenziswa izikhathi ezine.
(2) beka isihlabathi esiphakathi nendawo ( esimahhadla) esingu-0.3m.Ngemva kokulinganisa okwenziwa ngesandla nokomshini, irola yokudlidliza engu-25T izocindezelwa i-static kabili.
(3) ukubeka i-PP Biaxial Geogrid, PP Biaxial Geogrid ebeka phansi kufanele ilingane, iminyene, ngokuvamile ibe isicaba, iqonde, ayikwazi ukugqagqana, ingagoqeki, i-kink, i-geogrid emibili eseduze ukuze igoqe u-0.2 m, futhi eduze kwengxenye engemuva yodonga we-geogrid lap njalo ngemitha elingu-1 ngokusebenzisa ukuxhunywa kwezintambo ezingu-8, kanye nokubekwa kwe-grille, 1.5 2 m nge-U zonke izinzipho ezigxiliswe phansi.
(4) ngemva kokuba ungqimba lokuqala lwe-PP Biaxial Geogrid lugandayiwe, ungqimba lwesibili lwesihlabathi esiphakathi nendawo (amaholoholo) esiwugqinsi oluwu-0.2m luzogcwaliswa, lube nogqinsi oluphelele luka-0.5m.Four, amashumi ayisishiyagalombili nambili, amashumi ayisishiyagalombili nambili.Okukodwa, isikhombisa eziyisikhombisa.Izindlela: imoto eya endaweni yokwakha elayishwe ukuchithwa kwesihlabathi ohlangothini lombhede womgwaqo, bese kuthi ngogandaganda oshayelwa iphushele phambili, ibeke ezinhlangothini zombili zokugcwaliswa kwe-subgrade ngemva kobubanzi obungu-0.1 m 2 m, phinda ungqimba lokuqala lwe-geogrid epheqa futhi ugcwalise ngo-0.1 amamitha esihlabathi esimahhadla, ukuvinjelwa nhlangothi zombili ukuya maphakathi nokugcwalisa nokuqhubeza, kuvinjelwe zonke izinhlobo zemishini ngaphandle kokugcwalisa isihlabathi (i-coarse) geogrid esabelweni sethrafikhi, ukuze kungaqinisekisa i-geogrid ebushelelezi, ungagubhu, ungashwabani, hlala ngaphakathi. isendlalelo sesibili (i-coarse) ngemuva kwesihlabathi esibushelelezi, ukulinganisa izinga, vimbela ukushuba kokugcwalisa okungalingani, ngemva kokulinda ukubona nokulungisa i-25 t vibratory roller static pressure kabili.
(5) indlela yokwakha ungqimba lwesibili lwe-geotechnical grating iyafana neyesendlalelo sokuqala, futhi isihlabathi esiphakathi (esiqinile) esingu-0.3m ekugcineni sigcwaliswa. Indlela yokugcwalisa iyafana neyesendlalelo sokuqala. , futhi ingcindezi emile ye-25T roller isetshenziswa izikhathi ezimbili, ukuze ukuqiniswa kwesisekelo se-subgrade kuqedwe.
(6) kungqimba lwesithathu (olugqinsi) ukuhlanganisa isihlabathi, longitudinal emthambekeni ohlangothini ngalunye eduze umzila laying geogrid imidwebo emibili, ithanga 0.16 m, ixhunywe ngendlela efanayo, bese uqala ukwakhiwa komhlaba, laying geogrid ukuvikelwa emthambekeni, kumele kukalwa ohlangothini ngalunye olubekwe phansi, uhlangothi ngalunye ukuze kuqinisekiswe ukuthambekela ngemva kokulungiswa kwe-geogrids ukuhlaziya okushunyekiwe ngaphakathi kuka-0.10 m.
(7) i-geogrid yemithambeka ngayinye igcwaliswa ngezendlalelo ezimbili zenhlabathi, okungukuthi, lapho ukujiya kungu-0.8m, ungqimba lwe-geogrid luzobekwa nhlangothi zombili ngesikhathi esisodwa, bese kuba ngendlela efanayo, luze lubekwe. ngaphansi kwenhlabathi endaweni yehlombe yomgwaqo.
(8) ngemva kokugcwaliswa kwe-subgrade, i-slope izolungiswa ngesikhathi, futhi unyawo lomthambeko luzovikelwa ngama-slabs omile.I-subgrade izonwetshwa ngo-0.3m ohlangothini ngalunye futhi i-1.5% yokuhlala izobe igcinwe.
