Ukuqinisa I-Basalt Fiber Ezicelweni Zobunjiniyela Ezisebenzayo kanye Nocwaningo
1.I-Basalt Fiber ukuqinisa ezindaweni zomgwaqo zekhonkrithi
Izitebhisi zekhonkrithi eziqinisiwe njalo zilawula ukuqhekeka ngenxa yokuncipha ngokubeka inani elanele lemigoqo yokuqinisa ohlangothini olude. Lo mklamo awugcini nje ngokuthuthukisa amandla okulayisha kanye nokuqina komgwaqo omkhulu kodwa futhi uthuthukisa indawo yokushayela yezimoto ngokungahlinzeki ngamalunga okunwebeka kanye nokufinyela ngesikhathi UkwakhiwaKodwa-ke, njengoba isakhiwo sendlela singenakuvalwa ngokuphelele, izici ezifana nokungena kwamanzi emvula kanye nokwanda kweqhwa kungaholela ekugqwaleni kokuqina kwensimbi, okuthinta kakhulu impilo yokusebenza komgwaqo omkhulu.
I-Basalt fiber ukuqinisa kungasetshenziswa esikhundleni sokuqinisa insimbi yendabuko yezindlela zekhonkrithi eziqiniswe njalo ngenxa yokumelana kwayo okuhle kakhulu nokugqwala kanye namandla aphezulu okuthambekela. Lesi sixazululo esihlukile sixazulula ngempumelelo inkinga yokugqwala kwensimbi, ngaleyo ndlela sithuthukisa kakhulu ukuqina kwendlela yekhonkrithi. Ngaphezu kwalokho, i-basalt fiber Ukuqinisa kungokwezinto ezisebenzisa ikhabhoni ephansi futhi ezinobungani nemvelo, futhi inzuzo yaso yentengo izobonakala kakhulu ngokuncipha kwezinsizakusebenza zensimbi. Izifundo ezikhona zibonise ukuthi ukusebenzisa ukuqinisa kwe-BF-RP ezindleleni zekhonkrithi kubonisa izinzuzo ezisobala maqondana nokuqina nokumelana nokugqwala, kanti ubunzima bokwakha kanye nentuthuko kufana nokuqinisa insimbi. Kodwa-ke, ngenxa ye-modulus ephansi yokuqina kokuqinisa kwe-BF-RP, kuyadingeka ukwandisa kancane isilinganiso sayo sokuqinisa, ngokuvamile phakathi kuka-0.78% no-1.0%, kanye nokwamukela umqondo wokuklama "ububanzi bokuqinisa obuncane kanye nesikhala esiseduze".
2.Ucwaningo ngokuqiniswa kwefayibha ye-basalt ekuqiniseni amakholomu okucindezela angavamile ekhonkrithi amafushane
Izindlela zokuqinisa zendabuko zivame ukusebenzisa insimbi ekhiqizwe ngaphandle, kodwa le ndlela inzima ekwakheni futhi ayimelani kahle nokushisa okuphezulu nokugqwala. Izakhiwo ezilula, ezinamandla aphezulu, ezishisa kakhulu nezimelana nokugqwala zezinto ze-basalt fiber ziletha ukukhetha okusha kwenqubo yokuqinisa. Njengamanje, ubuchwepheshe bokuqinisa be-bonded i-basalt fiber amashidi asevuthiwe, kodwa ucwaningo lokuthuthukisa umthamo womthwalo oguquguqukayo wamakholomu ekhonkrithi ngokufaka imisipha ye-basalt fiber luncane kakhulu. Izincwadi ezifanele zibonisa ukuthi i-basalt fiber Ukuqinisa kuthuthukisa kakhulu amandla okugoba ohlangothini lwezinsika zekhonkrithi futhi kungathuthukisa kakhulu amandla okuthwala umthwalo ngokuhlanganisa indlela yokukhipha indwangu ye-basalt fiber ngaphandle.
Ukulandelana kokwakhiwa kokuqiniswa kwe-basalt fiber okufakiwe kungokulandelayo:
- Vula umsele ngokuya ngobukhulu bomklamo
- Geza umsele
- Faka i-bonding agent (i-epoxy resin adhesive)
- Ukushumeka imigoqo ye-BF-RP
- Gcwalisa nge-binder ngokulinganayo
- Linda ukuthi i-binder iphole bese wenza ukwelashwa kwendawo.
Ngokuhlanganisa nendwangu ye-basalt fiber ekhishwe ngaphandle, ukuqinisa kwe-BF-RP kungagwema ngempumelelo isimo sokushelela nokuqhekeka enkambisweni yokucindezeleka, ukwakhiwa kulula futhi kusebenza kahle, futhi kuthatha isikhala esincane, esinezinzuzo ezingenakuqhathaniswa.
3.Imishayo yekhonkrithi eqinisiwe ye-basalt fiber
Ukuqinisa i-BF-RP kuyinto yokuqinisa engeyona eyensimbi enobungani nemvelo, enamandla aphezulu futhi enezici ezifana nokumelana nokugqwala, ukuvikela ngogesi, kanye nokumelana nokukhathala, okwenza kube yindlela ekhethwayo esikhundleni sokuqinisa insimbi kumaphrojekthi athile akhethekile. Kodwa-ke, ngokungafani nemigoqo yensimbi evamile, imigoqo ye-BF-RP ayinayo iphuzu elibalulekile lokukhiqiza futhi ine-modulus ephansi yokuguquguquka, okungaholela ekuphambukeni okukhulu kwemigoqo yekhonkrithi ebhekene nomthwalo ofanayo. Nakuba umonakalo wekhonkrithi ngokuqinisa i-BF-RP uqhekeka futhi ungenaso isibikezelo esicacile, ukhiqiza ukuguqulwa okukhulu ngaphambi komonakalo, okuthi esikhundleni salokho kunikeze isixwayiso ngokuphepha kwesakhiwo.
Uma isakhiwo sinezidingo eziqinile zokuqhekeka kwekhonkrithi, kubalulekile ukucabangela ukufaka i-prestressing kuma-tendons e-basalt fiber, noma ukwandisa i-modulus yawo yokuguquguquka, bese uwaxuba futhi uwafanise nokuqinisa insimbi ukuqinisekisa ukuzinza nokuphepha kwesakhiwo.
