I-Basalt Fiber Reinforcement in Practical Engineering Applications and Research

1.I-Basalt Fiber ukuqiniswa emigwaqweni egandaywe ngokhonkolo

Imigwaqo kakhonkolo eqiniswe ngokuqhubekayo ilawula ukuqhekeka ngenxa yokuncipha ngokubeka inani elanele lemigoqo yokuqinisa ohlangothini lwe-longitudinal. Lo mklamo awugcini nje ngokuthuthukisa umthamo wokulayisha kanye nokuqina komgwaqo onguthelawayeka kodwa futhi uthuthukisa indawo yokushayela yezimoto ngokunganikezi amajoyinti okunwetshwa nokufinyezwa ngesikhathi. Ukwakha. Kodwa-ke, njengoba isakhiwo se-pavement singakwazi ukuvalwa ngokuphelele, izici ezifana nokungena kwamanzi emvula kanye nokukhuphuka kwesithwathwa kungaholela ekugqwaleni kokuqiniswa kwensimbi, okuthinta kakhulu impilo yesevisi yomgwaqo omkhulu.

I-basalt fiber ukuqinisa kungasetshenziswa esikhundleni sokuqiniswa kwensimbi yendabuko emigwaqweni kakhonkolo eqinisiwe ngokuqhubekayo ngenxa yokumelana nokugqwala okuhle kakhulu kanye namandla aphezulu okudonsa. Lesi sixazululo esihlukile siyixazulula ngempumelelo inkinga yokugqwala kwensimbi, ngaleyo ndlela sithuthukise ngokuphawulekayo ukuqina komgwaqo ogandaywe ngokhonkolo. Ngaphezu kwalokho, i-basalt fiber ukuqiniswa kungokwezinto ezinekhabhoni ephansi kanye nemvelo, futhi inzuzo yakhona yentengo izogqama kakhulu ngokuncipha kwemithombo yensimbi. Ucwaningo olukhona lubonise ukuthi ukusebenzisa i-BF-RP yokuqinisa emigwaqweni ekhonkolo kukhombisa izinzuzo ezisobala mayelana nokuqina nokumelana nokugqwala, futhi ubunzima bokwakha nenqubekela phambili kuqhathaniswa nalokho okuqinisa insimbi. Kodwa-ke, ngenxa ye-modulus ephansi kakhulu yokunwebeka kwe-BF-RP yokuqinisa, kuyadingeka ukwandisa kancane isilinganiso sayo sokuqinisa, ngokuvamile phakathi kuka-0.78% no-1.0%, futhi kwamukele umqondo wokuklama "wobubanzi obuncane bokuqinisa nokuvala isikhala".

2.Ucwaningo ngokuqiniswa kwefayibha ye-basalt ekuqiniseni amakholomu amafushane kakhonkolo wokucindezelwa

Izindlela zendabuko zokuqinisa ngokuvamile zisebenzisa insimbi ephuma ngaphandle, kodwa le ndlela inzima ekwakhiweni futhi ayinakho ukumelana nezinga lokushisa eliphezulu nokugqwala. Izakhiwo ezilula, ezinamandla, izinga lokushisa eliphezulu kanye ne-corrosion-resistant yezinto ze-basalt fiber ziletha ukukhetha okusha kwenqubo yokuqinisa. Njengamanje, ubuchwepheshe bokuqiniswa kwe-bonded i-basalt fiber amashidi avuthiwe, kodwa ucwaningo lokuthuthukisa umthamo womthwalo oguquguqukayo wamakholomu kakhonkolo ngokushumeka imisipha ye-basalt fiber incane uma kuqhathaniswa. Izincwadi ezifanele ziyakubonisa lokho i-basalt fiber ukuqiniswa kuthuthukisa kakhulu umthamo wokugoba we-lateral wamakholomu kakhonkolo futhi kungaqhubeka nokuthuthukisa umthamo wokuthwala umthwalo ngokuhlanganisa indlela yokukhipha indwangu ye-basalt fiber.

Ukulandelana kokwakhiwa kwe-basalt fiber reinforcement eshumekiwe kanje:

1. Vula i-groove ngokusho kosayizi wokuklama
2. Geza umsele
3. Faka i-ejenti yokubopha (i-epoxy resin adhesive)
4. Ishumeka imigoqo ye-BF-RP
5. Gcwalisa nge-binder ngokulinganayo
6. Linda ukuthi i-binder ilulame bese wenza ukwelashwa okungaphezulu.

Ngokuhlanganisa nendwangu ye-basalt fiber ekhishwe ngaphandle, ukuqiniswa kwe-BF-RP kungagwema ngokuphumelelayo ukwenzeka kokushelela nokusabalalisa ngesikhathi sokucindezeleka, ukwakhiwa kulula futhi kusebenza kahle, futhi kuthatha indawo encane, enezinzuzo ezingenakuqhathaniswa.

3.Izigxobo zikakhonkolo eziqinisiwe ze-Basalt fibre

I-BF-RP reinforcement iyinto enobungani bemvelo, enamandla aphezulu engaqinisi insimbi enezinto ezinjengokumelana nokugqwala, ukufakwa kwe-electromagnetic, nokumelana nokukhathala, okuyenza ibe enye indlela ekhethwayo kunokuqinisa insimbi kumaphrojekthi athile akhethekile. Kodwa-ke, ngokungafani nemigoqo yensimbi evamile, imigoqo ye-BF-RP ayinayo iphuzu elibalulekile lokukhiqiza futhi ine-modulus ephansi yokunwebeka, okungase kubangele ukuphambuka okukhulu kwemishayo yekhonkrithi engaphansi komthwalo ofanayo. Nakuba umonakalo kakhonkolo nge-BF-RP ukuqinisa i-brittle futhi ingenayo i-prognosis ecacile, ikhiqiza ukuguqulwa okukhulu ngaphambi kokulimala, okuhlinzeka ngesixwayiso sokuphepha kwesakhiwo.

Uma isakhiwo sinezidingo eziqinile zokuqhekeka kwekhonkrithi, kuyadingeka ukucabangela ukusebenzisa i-prestressing kumathenda e-basalt fiber, noma ukwandisa i-modulus yawo yokuqina, nokuxuba nokuwafanisa nokuqiniswa kwensimbi ukuze kuqinisekiswe ukuzinza nokuphepha kwesakhiwo.
