I-geogrid yentsimbi yeplastiki yentsimbi ekwaziyo ukuthwala amandla omgaqo kaloliwe ongaphantsi kwetonela

Iinkcukacha zeMveliso
I-Fiberglass geogrid yeyona nto ibalaseleyo ye-geosynthetic esetyenziselwa ukuqinisa indlela, ukuqinisa indlela endala, ukuqinisa isiseko sendlela kunye nesiseko somhlaba othambileyo. I-Fiberglass geogrid yimveliso eqinileyo eyenziwe ngamandla aphezulu e-alkali-free fiberglass ngokusebenzisa inkqubo yokunitha ye-warp ephucukileyo yamazwe ngamazwe kwaye igqunywe ngonyango lomphezulu. Inamandla aphezulu okuqina kunye nobude obuphantsi kuzo zombini izikhombisi ze-warp kunye ne-weft, kwaye ineempawu ezibalaseleyo zokumelana nobushushu obuphezulu, ukumelana nokubanda okuphantsi, ukumelana nokwaluphala, ukumelana nomhlwa, njl njl. Umgaqo kaloliwe, ukhuseleko lwethambeka ledama, umgaqo weenqwelo-moya, ulawulo lwesanti kunye nezinye iiprojekthi zobunjineli.

Inxalenye ephambili ye-fiberglass yile: i-silicon oxide, i-inorganic materials, iipropati zayo zomzimba kunye neekhemikhali zizinzile kakhulu, kwaye zinemodyuli ephezulu, ukuxhathisa ukunxiba kunye nokumelana nokubanda okugqwesileyo, akukho ngqungquthela yexesha elide; ukuzinza okuhle kwe-thermal; ulwakhiwo lwemesh ukwenzela ukuba isitshixo esidityanisiweyo esidityanisiweyo kunye nomda; ukuphucula umthamo wokuthwala umxube we-asphalt. Ngenxa yokuba umphezulu ugqunywe nge-asphalt ekhethekileyo eguqulweyo, ineempawu ezimbini ezidibeneyo, zombini iipropathi ezigqwesileyo ze-fiberglass kunye nokuhambelana nomxube we-asphalt, ophucula ukuxhathisa kwe-abrasion kunye nokumelana nokucheba kwe-geogrid.

Iimpawu zeemveliso ze-fiberglass geogrid
Imveliso inamandla amakhulu, ubude obuphantsi, ukumelana nobushushu obuphezulu, imodyuli ephezulu, ubunzima bokukhanya, ukuqina okulungileyo, ukuxhathisa ukubola, ubomi obude, njl. Ukhuseleko lwethambeka, unyango oluphuculweyo lwendlela kunye nebhulorho kunye nezinye iindawo zobunjineli, ezinokunika uphuculo lwendlela, ukuqinisa, ukuthintela ukudinwa kwepavement, kushushu. kunye nokwandiswa okubandayo kunye nokuqhekeka okubonakalayo ngezantsi, kwaye kunokusasazwa, ukwandisa ubomi benkonzo yendlela yendlela, amandla aphezulu okuqina okunyuka okuphantsi, akukho kukhwela ixesha elide, ukuzinza okuhle komzimba kunye neekhemikhali, ukuzinza okuhle kwe-thermal, ukumelana nokudinwa kokuqhekeka, ukumelana nobushushu obuphezulu. , iqondo lokushisa eliphantsi liyancipha ukuchasana nokuqhekeka, ukulibaziseka ukuncitshiswa kweentanda zokubonisa.

Inkqubo yokwakha i-fiberglass geogrid
(1) Okokuqala, chaza ngokuchanekileyo umgca wokuthambeka kwendlela, ukuze kuqinisekiswe ububanzi bebhedi yendlela, icala ngalinye landiswa nge-0.5m, ukomiswa komhlaba olungileyo wokulinganisa emva kokusebenzisa i-25T i-vibratory roller static pressure. amaxesha amabini, kwaye emva koko 50T uxinzelelo ukothuka izihlandlo ezine, indawo engalinganiyo nge manual leveling.
(2) Ukubeka isanti eyi-0.3m engqindilili (erhabaxa) yesanti, incwadana enemigangatho yomatshini, i-25T vibration roller static pressure amaxesha amabini.
(3) ukubeka i-geogrid, umgangatho osezantsi we-geogrid kufuneka ube mcaba, uxinene, ngokubanzi kufuneka ubekwe mcaba, ngokuthe tye, kungabikho ukuhlangana, akukho curl, i-kink, i-geogrid ezimbini ezimeleneyo kufuneka zijikeleze nge-0.2m, kwaye ecaleni kwendlela ye-roadbed geogrid lap inxalenye nganye I-1m eneNombolo ye-8 yocingo lokudibanisa i-interpolation, kwaye kwiigridi ezibekwe, rhoqo nge-1.5-2m nge Izikhonkwane ze-U ezigxininiswe emhlabeni.
4 , kuqala iimitha ezi-2 kumacala omabini omandlalo wendlela emva kokuzalisa i-0.1m, umaleko wokuqala we-geogrid wasongwa waza wazaliswa nge-0.1m ngaphakathi (erhabaxa) isanti, thintela macala omabini ukuya embindini wokuzaliswa kunye nokuqhubela phambili, ukunqanda zonke iintlobo zoomatshini xa kungekho Oku kunokuqinisekisa ukuba i-geogrid ithe tyaba, ngaphandle kwamagubu kunye nemibimbi, kwaye emva kokuba umaleko wesibini wesanti ephakathi (erhabaxa) ithe tyaba. , umlinganiselo wezinga kufuneka uqhutywe ukukhusela ukungalingani kokuzaliswa kobunzima, kunye ne-25T i-vibratory roller kufuneka isetyenziswe ngamaxesha amabini emva kokuba ukulinganisa kuchanekileyo.
5 Ukuqiniswa kwe-roadbed substrate kugqityiwe.
(6) kuluhlu lwesithathu lwesanti (erhabaxa) etyunyuziweyo, ecaleni komgca wendlela yobude kumacala omabini ethambeka elibekwe i-geogrid ezimbini, i-lap 0.16m, kwaye iqhagamshelwe ngendlela efanayo, kwaye emva koko iqalise imisebenzi yokwakha umhlaba, ibeka i-geogrid. ukhuseleko kwithambeka, umaleko ngamnye kufuneka ulinganiswe ngaphandle komphetho wokubekwa, kwicala ngalinye ukuqinisekisa ukuba i-slope ukulungisa i-geogrid ingcwatywe kwindawo. ithambeka 0.10m.
(7) Kwimigangatho emibini yomhlaba ezaliswe, okt i-0.8m ubukhulu, umaleko we-geogrid kufuneka wondlalwe macala omabini ngaxeshanye, njalo njalo de ufikelele kumphezulu wegxalaba lendlela.
(8) emva kokuba umandlalo wendlela ugcwalisiwe, ukulungiswa kwethambeka kwangexesha, kunye nokhuseleko lwamatye olomileyo kumazantsi ethambeka, icandelo lendlela ukongeza ekwandiseni i-0.3m kwicala ngalinye, kwaye igcine i-1.5% yendlela yokumanzisa.
