Ipuleti lobuso le-granite liphuma efektri linesitifiketi sokuba yisicaba esinamathiselwe kulo. Ezinyangeni eziyisithupha kamuva, egumbini lokuhlola lekhasimende, lelo puleti elifanayo lingalinganisa ngendlela ehlukile — hhayi ngoba itshe lishintshe ukwakheka, kodwa ngoba igumbi elizungezile lalinganisa. Lena ingenye yemithombo evamile, futhi engavinjelwa, yokushintsha kokulinganisa emalabhorethri okukala.
I-granite ikhethwa ukuze isetshenziswe ematafuleni okulinganisa kanyeizisekelo zokunembangoba nje imelana nokuguquguquka kangcono kunensimbi ephonswe noma insimbi. Ayigqwali, inokukhula okuphansi kokushisa, futhi imanzisa kahle ukudlidliza. Kodwa “ukumelana nokuguquguquka” akufani “nokungavikeleki kukho.” Ukugcinwa okungafanele — ukushintshashintsha kwezinga lokushisa, umswakama, ukwesekwa okungalingani, noma ukuphathwa ngokunganaki — kungenza buthule izinyanga zomsebenzi wokugaya nokubopha ngaphambi kokuba ipuleti lifike phansi esitolo sekhasimende.
Kungani Izimo Zokugcina Izinto Zibaluleke Kakhulu Kunokuba Abantu Bacabanga
I-granite iyinto yemvelo ekristalu, futhi njenganoma yisiphi isiqinile, iyasabela endaweni ezungezile. Izici ezintathu zibangela iningi lezinkinga ezihlobene nokugcinwa esizibonayo ensimini:
Ukushintshashintsha kwezinga lokushisa. Ngisho noma kune-coefficient ephansi yokwanda kokushisa, i-granite slab evezwe ekushintsheni kwansuku zonke okungu-10–15°C izokhula futhi inciphe ezingeni elincane kakhulu. Ngokuhamba kwesikhathi, ikakhulukazi ngokushisa okungalingani — ukukhanya kwelanga kushaya unqenqema olulodwa lwepuleti, noma isifudumezi sendlu yokugcina impahla sijikeleza futhi sivala — lokhu kungaletha ukuphambuka okulinganiselwe kokusicaba, ikakhulukazi kumapuleti aphansi kuya ekubekezeleleni okungaphansi kwe-micron.
Umswakama kanye nokumuncwa komswakama. I-Granite inezimbobo ezithile, futhi itshe elishibhile - ikakhulukazi imabula ethengiswa ngaphansi kwelebula "le-granite" ngabaphakeli abangacopheleli kakhulu - imunca umswakama kalula futhi ithambekele kakhulu ekugobekeni nasekudayeni ubuso. Lesi esinye sezizathu zokukhetha izinto ezibalulekile njengekhwalithi yomshini. Itshe elinobukhulu obuphezulu, eliphakathi kuka-3,000 kg/m³ noma ngaphezulu, limelana nokumuncwa komswakama kangcono kakhulu kunezinye izindlela ezisezingeni eliphansi.
Ukusekela nokusatshalaliswa komthwalo. Ipuleti le-granite eligcinwe phansi elingalingani, noma elisekelwe emaphethelweni alo kuphela, lizogoba ngokuhamba kwesikhathi ngaphansi kwesisindo salo - isimiso esifanayo esisebenza kunoma yiliphi i-slab eqinile ngaphansi komthwalo oqhubekayo. Imishayo emide yokunemba kanye namapuleti amakhulu azwela kakhulu kulokhu, ngoba ngisho namamilimitha ambalwa esikhala esingasekelwa angahunyushwa abe umnsalo obonakalayo.
Indlela Indawo Enhle Yokugcina Izinto Ebukeka Ngayo Empeleni
Ngokusekelwe eminyakeni yokuphatha izingxenye ze-granite ngaphambi nangemva kokugaya, imikhuba embalwa yenza umehluko njalo:
- Gcina amapuleti ezindaweni zawo zokusekela eziklanyelwe wona (ngokuvamile amaphuzu amathathu noma amaphuzu eBessel ezingxenyeni ezinde), ungalokothi uthambekele endaweni engalingani.
- Gcina izinga lokushisa elizungezile lizinzile — kungcono ukuthi libe ngaphakathi kwebhande elifanayo lapho ipuleti lizosetshenziswa khona, ugweme ukusondela eminyango, emafasiteleni, noma emithonjeni yomoya ye-HVAC.
- Lawula umswakama ukuze uvimbele ukufuduka komswakama ungene ezimbotsheni ezincane zetshe, ikakhulukazi amapuleti alinde ukulinganiswa kokugcina.
- Gwema ukubeka izingxenye zegranite ngqo phezu kwenye ngaphandle kwezikhala ezifanele; ukuthintana kwephuzu ngaphansi kwesisindo kuyimbangela evamile yokuqhekeka kanye nokucindezeleka kwendawo.
- Hlola kabusha ukuthi i-flat ithambile yini ngemva kwesikhathi eside sokugcina ngaphambi kokuba ipuleti liphinde lisebenze, kunokuba ucabange ukuthi isitifiketi sokuqala sisasebenza.
Isakhiwo sethu sisebenza ngamakamelo alawulwa amazinga okushisa nomswakama ikakhulukazi kulesi sigaba sokukhiqiza — hhayi nje ukuhlolwa kokugcina, kodwa namapuleti okubeka izinto phakathi kokudlula kokugaya nangaphambi kokuthunyelwa. Iphansi kula makamelo liyi-concrete eqinisiwe ehlanganisiwe, ehlukaniswe nesakhiwo esizungezile ngamajoyinti okunwebeka afana nesitayela sokuzamazama komhlaba, okuvimbela ukudlidliza nokuqina ekuthinteni izingxenye ezigciniwe. Kuyinto engabonakali ephepheni le-spec, kodwa ngokuvamile umehluko phakathi kwepuleti eligcina ukuqina kwalo okuqinisekisiwe iminyaka kanye nelidinga ukuphinda lihlanganiswe phakathi nesizini.
Umthwalo Wemfanelo Ohlanganyelwe
Abakhiqizi bangalawula okwenzekayo ngaphambi kokuthunyelwa. Okwenzekayo ngemva kwalokho - endaweni yokwamukela amakhasimende, endaweni yokugcina impahla ehlanganyelwe, noma elebhu engakaqedi ukwakha kwayo ukulawula isimo sezulu - akusekho ezandleni zomhlinzeki. Lokho kuyingxenye yokuthi kungani imibhalo ibalulekile: izitifiketi zokulinganisa ezilandelwa esikhungweni se-metrology esiqashelwayo zinikeza isisekelo sokulinganisa ngemuva kwesikhathi, kanye nokuqinisekiswa kabusha njalo (ngonyaka, noma ngemva kwanoma yikuphi ukuchayeka okukhulu kwemvelo) kuyindlela ejwayelekile phakathi kwamalebhu athatha ukuphindaphindeka ngokungathi sína.
Amatafula okulinganisa i-granite namapuleti obuso kuyitshalomali yesikhathi eside kunoma yiliphi ilabhorethri yokulinganisa, igumbi le-CMM, noma umugqa wokuhlanganisa ngokunembile. Ukuqina kwezinto kuyinzuzo yangempela kunezinye izindlela zensimbi noma zensimbi ephonswe, kodwa kuphela uma lokho kuqina kungaphazanyiswa yigumbi elikulo. Ukuphatha indawo yokugcina izinto njengengxenye yochungechunge lokunembile — kunokuthi kube yinto ecatshangelwe kamuva uma ipuleti selidlulile ekuhlolweni kokugcina — kuwumkhuba omncane wokusebenza ozikhokhela impilo yokusebenza kwemishini.
