Amapharamitha obuchwepheshe we-Granite Mechanical Foundation.

 

IGranite, iDranite ye-Igroed Roble esetshenziswa kabanzi, idume ngokuqina kwayo namandla, okwenza kube yinto efanelekile yezisekelo zemishini emisebenzini ehlukahlukene yokwakha. Ukuqonda amapharamitha wezobuchwepheshe wezisekelo zemishini e-Granite zibalulekile onjiniyela kanye nezakhiwo zokwakha ukuqinisekisa ubuqotho obuhlelekile kanye nokuphila isikhathi eside.

Enye yamapharamitha obuchwepheshe obuchwepheshe bama-granite amandla ayo acindezela, avela ngokujwayelekile kusuka ku-100 kuye ku-300 MPA. La mandla aphezulu acindezelayo avumela ama-granite ukuthi abekezelele imithwalo ebalulekile, okwenza kube lufanele imishini esindayo kanye nemishini. Ngokwengeziwe, i-Granite ibonisa i-porsiotion ephansi, ngokuvamile phakathi kuka-0,1% kuya ku-0,5%, okunomthelela ekumelaneni kwayo ekungeneni kwamanzi kanye nasekusebenzeni kwamakhemikhali, okuthuthukisa ukufaneleka kwayo kwezisekelo zemishini.

Enye iparamitha ebalulekile i-modulus ye-elasticity, eyayi-granite icishe ibe ngu-50 kuye ku-70 GPA. Le mpahla ikhombisa ukuthi lokho okuzolimaza kangakanani ngaphansi kwengcindezi, ukuhlinzeka ngokuqonda ekusebenzeni kwayo ngaphansi kwemithwalo enamandla. I-coeffient ephansi ephansi ye-granite ye-granite, cishe ngo-5 kuye ku-7 x 10 ^ - ° 10

Ubukhulu bukaGranite, ngokuvamile phakathi kuka-2.63 kuya ku-2.75 g / cm³, nabo badlala indima ebalulekile ekwakhiweni okuyisisekelo. Ukuqina okuphezulu kunomthelela ekuqineni okuphelele kwesisekelo, kunciphisa ubungozi bokuxazululwa noma ukuguquka ngokuhamba kwesikhathi. Ngaphezu kwalokho, ukumelana kukaGranite ku-abrasion and ukugqokwa kwenza kube ukukhetha okuhle kwezisekelo ezibangelwa yithrafikhi enkulu noma ukucindezelwa kwemishini.

Ekuphetheni, amapharamitha wezobuchwepheshe wezisekelo zemishini egrenite, kufaka phakathi amandla acindezelayo, imodululo yokuqina, ipulasi eliphansi nobukhulu obuphakeme, anciphise ukusebenza kwawo njengento esesisekelo. Ngokufaka le ndawo, onjiniyela bangakwazi ukuklama izisekelo eziqinile neziqinile zemishini ezihlangabezana nezidingo zokwakhiwa kwanamuhla.
