Technical parameters yegranite mechanical nheyo.

 

Granite, ibwe rinoshandiswa zvakanyanya negineous dombo, rinozivikanwa nekusimba uye kusimba, zvichiita kuti rive chinhu chakanakira nheyo dzemakanika mumapurojekiti akasiyana ekuvaka. Kunzwisisa tekinoroji paramita yegranite mechanicha nheyo kwakakosha kune mainjiniya nevagadziri vekuvaka kuti vaone kutendeseka kwechimiro uye hupenyu hurefu.

Imwe yeakanyanya tekinoroji paramita yegranite isimba rayo rekumanikidza, iro rinowanzobva pa100 kusvika 300 MPa. Iri simba repamusoro rekumanikidza rinobvumira granite kumira mitoro yakakosha, ichiita kuti ive yakakodzera kune inorema muchina nemidziyo. Pamusoro pezvo, granite inoratidza yakaderera porosity, kazhinji iri pakati pe0.1% kusvika 0.5%, iyo inobatsira mukupokana kwayo nekupinzwa kwemvura uye nemamiriro ekunze emakemikari, zvichiwedzera kukwidziridza kukodzera kwayo kwemakanika nheyo.

Imwe paramende yakakosha ndiyo modulus ye elasticity, iyo yegranite inenge 50 kusvika 70 GPa. Ichi chivakwa chinoratidza kuti yakawanda sei iyo zvinhu zvichakanganisa pasi pekushushikana, ichipa manzwisisiro mukuita kwayo pasi pemitoro ine simba. Iyo yakaderera yekupisa yekuwedzera coefficient yegranite, yakatenderedza 5 kusvika 7 x 10 ^ -6 / ° C, inova nechokwadi chekuti inochengetedza kuvimbika kwayo kwechimiro kunyangwe nekuchinja kwekushisa, zvichiita kuti ive sarudzo yakavimbika yenheyo mumamiriro ekunze akasiyana.

Density yeGranite, kazhinji iri pakati pe2.63 kusvika 2.75 g/cm³, inoitawo basa rakakosha mukugadzira hwaro. Kuwanda kwepamusoro kunobatsira pakugadzikana kwese kwenheyo, kuderedza dambudziko rekugadzirisa kana kushanduka nekufamba kwenguva. Uyezve, kuramba kwegranite kune abrasion uye kupfeka kunoita kuti ive sarudzo yakanakisa kune nheyo dzakaiswa kune inorema traffic kana kushushikana kwemagetsi.

Mukupedzisa, iwo tekinoroji paramita yegranite mechanicha nheyo, inosanganisira kumanikidza simba, modulus ye elasticity, yakaderera porosity, uye yakakwira density, inosimbisa kushanda kwayo sechinhu chekutanga. Nekukwirisa zvivakwa izvi, mainjiniya anogona kugadzira hwaro hwakasimba uye hwakasimba hwemakina izvo zvinosangana nezvinodiwa zvekuvaka kwemazuva ano.
