Ukuqiniswa kweFayibha yeBasalt kwizicelo zobuNjineli obuSebenzayo kunye noPhando

1.IFayibha yeBasalt ukuqinisa kwipavumente zekhonkrithi

Iindlela zekhonkrithi eziqinisiweyo ngokuqhubekayo zilawula ukuqhekeka ngenxa yokunciphisa ngokubeka inani elaneleyo lemivalo yokuqinisa kwi-longitudinal direction. Olu yilo aluphuculi kuphela umthamo wokulayisha kunye nokuqina kohola wendlela kodwa ikwaphucula imeko yokuqhuba iimoto ngokungaboneleli ngokwandiso kunye nokuncipha kwamalungu ngexesha. Ukwakhiwa. Nangona kunjalo, ekubeni i-pavement structure ayikwazi ukuvalwa ngokupheleleyo, izinto ezinjengokungena kwamanzi emvula kunye nokunyuka kweqhwa kunokukhokelela ekugxunyekeni kokuqiniswa kwensimbi, echaphazela kakhulu ubomi benkonzo yomgwaqo omkhulu.

I-basalt fiber ukomeleza kunokusetyenziswa endaweni yokomelezwa kwentsimbi yesiko kwiipavumente zekhonkrithi ezomeleziweyo ngokuqhubekayo ngenxa yokumelana nokugqwesa kwayo okugqwesileyo kunye namandla aphezulu okuqina. Esi sisombululo sisombulula ngempumelelo ingxaki yokubola kwensimbi, ngaloo ndlela iphucula kakhulu ukuqina kwepavement yekhonkrithi. Ukwengeza, i-basalt fiber ukuqiniswa kungokwekhabhoni ephantsi kunye nezinto ezihambelana nokusingqongileyo, kwaye inzuzo yayo yexabiso iya kuba yinto evelele ngakumbi ngokuchithwa kwezixhobo zentsimbi. Izifundo ezikhoyo zibonise ukuba ukusebenzisa i-BF-RP ukuqiniswa kwiindlela zekhonkrithi kubonisa izibonelelo ezicacileyo malunga nokuqina kunye nokumelana nokubola, kunye nobunzima bokwakha kunye nenkqubela phambili ifaniswa nokuqiniswa kwentsimbi. Nangona kunjalo, ngenxa yemodyuli ephantsi ye-elasticity ye-BF-RP yokuqinisa, kuyimfuneko ukunyusa kancinane umlinganiselo wokuqiniswa kwayo, ngokuqhelekileyo phakathi kwe-0.78% kunye ne-1.0%, kunye nokwamkela ingcamango yoyilo "yedayamitha yokuqinisa encinci kunye nesithuba esisondeleyo".

2.Uphando malunga nokuqiniswa kwefayibha ye-basalt ekuqiniseni iikholamu ezimfutshane zekhonkrithi eccentric

Iindlela zokuqinisa zemveli zihlala zisebenzisa intsimbi ephuma ngaphandle, kodwa le ndlela inzima ekwakhiweni kwaye inokumelana nokushisa okuphezulu kunye nokubola. Izinto ezilula, eziphakamileyo, ukushisa okuphezulu kunye ne-corrosion-resistant properties ze-basalt fiber zizisa ukhetho olutsha kwinkqubo yokuqinisa. Okwangoku, iteknoloji yokuqinisa i-bonded i-basalt fiber amaphepha avuthiwe, kodwa uphando ekuphuculeni umthamo womthwalo we-flexural wekholamu zekhonkrithi ngokufaka i-basalt fiber tendons incinci. Uncwadi olufanelekileyo lubonisa oko i-basalt fiber ukuqiniswa kuphucula ngokubonakalayo umthamo wokugoba wecala leekholamu zekhonkrithi kwaye kunokunyusa ngakumbi umthamo wokuthwala umthwalo ngokudibanisa indlela yokukhupha ilaphu le-basalt fiber.

Ukulandelelana kolwakhiwo lwe-basalt fiber reinforcement lulandelayo:

1. Vula i-groove ngokobungakanani boyilo
2. Hlamba i-groove
3. Faka i-arhente yokudibanisa (i-epoxy resin adhesive)
4. Ukufakela imivalo ye-BF-RP
5. Gcwalisa nge-binder ngokulinganayo
6. Lindela isibophelelo ukuba sinyange kwaye emva koko wenze unyango olungaphezulu.

Ngokudibanisa nelaphu le-basalt fiber ekhutshwe ngaphandle, ukuqiniswa kwe-BF-RP kunokuphepha ngokufanelekileyo i-phenomenon ye-slipping kunye ne-spalling kwinkqubo yoxinzelelo, ukwakhiwa kulungeleka kwaye kusebenze, kwaye kuthatha indawo encinci, enenzuzo engenakulinganiswa.

3.Iifayibha zeBasalt eziqinisiweyo zekhonkrithi

Ukuqiniswa kwe-BF-RP yinto ehambelana nokusingqongileyo, amandla aphezulu angeyontsimbi yokuqinisa izinto ezineempawu ezinjengokumelana nokubola, ukugqunywa kwe-electromagnetic, kunye nokumelana nokudinwa, oko kuyenza ibe yindlela ekhethwayo yokuqiniswa kwentsimbi kwiiprojekthi ezithile ezizodwa. Nangona kunjalo, ngokungafaniyo nemivalo yentsimbi eqhelekileyo, imivalo ye-BF-RP ayinayo isivuno esibalulekileyo kwaye inemodyuli ephantsi ye-elasticity, enokubangela ukuphambuka okukhulu kweentsimbi zekhonkrithi eziphantsi komthwalo ofanayo. Nangona umonakalo wekhonkrithi kunye ne-BF-RP yokuqinisa i-brittle kwaye ayinayo i-prognosis ecacileyo, ivelisa i-deformation enkulu ngaphambi komonakalo, endaweni yoko inikezela isilumkiso sokhuseleko lwesakhiwo.

Ukuba isakhiwo sineemfuno ezingqongqo zokuqhekeka kwekhonkrithi, kuyimfuneko ukuqwalasela ukusebenzisa i-prestressing kwi-basalt fiber tendons, okanye ukwandisa i-modulus yabo ye-elasticity, kunye nokuxuba kunye nokudibanisa kunye nokuqiniswa kwensimbi ukuqinisekisa ukuzinza kunye nokhuseleko lwesakhiwo.
