Ibikoresho bya tekinike ya granite ya mashini foundation

 

Granite, urutare rukoreshwa cyane, ruzwiho kuramba n'imbaraga, rukaba ibikoresho byiza byububiko bwimashini mumishinga itandukanye yo kubaka. Gusobanukirwa ibipimo bya tekiniki ya granite yubukanishi ningirakamaro kuri ba injeniyeri n'abubatsi kugirango barebe ubusugire bwimiterere no kuramba.

Kimwe mu bikoresho byibanze bya tekinike ya granite nimbaraga zayo zo guhonyora, mubisanzwe kuva kuri 100 kugeza 300 MPa. Izi mbaraga zo guhonyora zituma granite ihanganira imizigo ihambaye, bigatuma ikoreshwa nibikoresho bikomeye. Byongeye kandi, granite yerekana ububobere buke, muri rusange hagati ya 0.1% na 0.5%, ibyo bikaba bigira uruhare mukurwanya kwinjirira mumazi hamwe nikirere cyimiti, bikarushaho kunoza imiterere yimashini.

Ikindi kintu cyingenzi ni modulus ya elastique, kuri granite igera kuri 50 kugeza 70 GPa. Uyu mutungo werekana uko ibikoresho bizahinduka mugihe uhangayitse, bitanga ubushishozi mubikorwa byacyo munsi yimitwaro ifite imbaraga. Coefficient yo kwagura ubushyuhe buke bwa granite, hafi 5 kugeza 7 x 10 ^ -6 / ° C, iremeza ko igumana ubusugire bwayo ndetse n’imihindagurikire y’ubushyuhe, bigatuma ihitamo ryizewe ku mfatiro z’ibihe bitandukanye.

Ubucucike bwa Granite, mubisanzwe hagati ya 2,63 na 2,75 g / cm³, nabwo bugira uruhare runini mugushushanya. Ubucucike buri hejuru bugira uruhare muri rusange muri fondasiyo, kugabanya ibyago byo gutura cyangwa guhinduka mugihe. Byongeye kandi, kuba granite irwanya abrasion no kwambara bituma ihitamo neza kubishingwe byatewe nurujya n'uruza rwinshi cyangwa imashini.

Mu gusoza, ibipimo bya tekinike ya fondasiyo ya granite, harimo imbaraga zo guhonyora, modulus ya elastique, ubukana buke, nubucucike bukabije, bishimangira imikorere yayo nkibikoresho fatizo. Mugukoresha iyi mitungo, injeniyeri zirashobora gushushanya urufatiro rukomeye kandi rurambye rwujuje ibyifuzo byubwubatsi bugezweho.
