Umuti urwanya ingese ku gice cyo hasi cy'igikoresho gipima umugozi: Akamaro gakomeye ka granite mu bidukikije bikonje.

Mu rwego rwo gupima neza, ibikoresho bipima imigozi bigira uruhare runini mu kwemeza ko ibice by’imigozi bifite imiterere n’imiterere bihamye. Gukomera no kudakomera kw’ibice byabyo mu bidukikije bikonje bigira ingaruka ku buryo butaziguye ku buryo ibipimo bihagaze neza ndetse n’igihe ibikoresho bimara. Guhangana n’ibidukikije bigoye cyane bifite ubushuhe bwinshi nko mu nganda no mu nkengero z’inyanja, ibibanza bya granite, bifite imiterere yihariye y’ibikoresho n’ibyiza byo kurwanya ingese, byabaye amahitamo meza ku bikoresho bipima imigozi.

Imbogamizi z'ibidukikije bitose ku rufatiro rw'ibikoresho byo gupima
Ahantu hatose ni ikibazo gikomeye gihura n’ishingiro ry’ibikoresho bipima icyuma gipima amazi. Ubushuhe buri mu kirere ntibuzinjira gusa ku buso bw’ishingiro kugira ngo bukore icyuma cy’amazi, ahubwo bushobora no kwinjira imbere mu bikoresho. Ku byuma, nk’ibyuma bishongeshejwe cyangwa iby’icyuma, ahantu hatose hashobora gutuma habaho ogisijeni n’ingufu byoroshye, bigatera kwangirika no gushibuka kw’ubuso bw’ishingiro, ibyo bigatuma bigira ingaruka ku buryo bwo gushyiraho no kudahindagurika kw’igikoresho gipima. Hagati aho, ingese ziterwa no kwangirika zishobora no kwinjira mu bice by’ishingiro by’igikoresho gipima neza, bigatera kwangirika no gufungana kw’ibice, ibyo bigira ingaruka zikomeye ku buryo bwo gupima neza no gukora neza kw’ibikoresho. Byongeye kandi, kwaguka kw’ubushyuhe n’ingaruka zo guhindagurika k’ubushuhe bishobora gutuma habaho impinduka nto mu bunini bw’ishingiro, bigatuma igereranya ry’ibipimo rihinduka kandi bigatera amakosa yo gupima adashobora kwirengagizwa.
Imiterere karemano y'icyatsi cya granite
Granite, nk'ubwoko bw'ibuye karemano, ifite akarusho gakomeye ko kurwanya ingese. Amabuye y'agaciro y'imbere ahinduka nk'ibumba kandi imiterere yayo ni miremire kandi ingana, bigatuma amazi atabasha kwinjira neza. Bitandukanye n'ibikoresho by'icyuma, granite ntabwo ihura n'ibintu bisanzwe bivanze na aside cyangwa alkaline. Nubwo yaba ishyizwe ahantu hatose harimo imyuka cyangwa ibinyobwa byangiza igihe kirekire, ishobora kugumana imiterere ihamye ya shimi kandi ntizagira ibibazo nko kwangirika cyangwa ingese.

Mu nganda zikora imashini mu turere two ku nkombe z'inyanja, ubushyuhe bw'ikirere mu mazu akorerwamo buhora buri hejuru mu mwaka wose kandi burimo umunyu runaka. Igikoresho gipima imiyoboro gifite ishingiro ry'icyuma kizagaragaza ibintu bigaragara birimo ingese mu mezi make gusa, kandi amakosa yo gupima azakomeza kwiyongera. Igikoresho gipima gifite ishingiro rya granite cyakomeje kuba cyiza kandi gishya nyuma y'imyaka myinshi gikoreshwa, kandi ubuziranenge bwacyo bwo gupima bwahoranye, bigaragaza neza imikorere myiza ya granite mu kurwanya ingese mu kirere gishyushye.
Ibyiza by'imikorere rusange y'ibice bya granite
Uretse kuba ifite ubushobozi bwo kurwanya ingese, ishingiro rya granite rifite n'ibindi byiza byinshi, ritanga uburinzi bwuzuye ku mikorere ihamye y'igikoresho gipima umugozi mu kirere gishyushye. Igipimo cy'ubushyuhe bwa granite ni gito cyane, ni 5-7 × 10⁻⁶/℃ gusa. Mu gihe cy'ihindagurika ry'ubushyuhe riterwa n'impinduka z'ubushuhe, ntabwo ihinduka cyane, bigatuma igenzura rihoraho. Hagati aho, imiterere myiza yo gutigita ya granite ishobora kwakira neza imitingito yo hanze. Nubwo ibikoresho byagira ingaruka nke bitewe n'umwuka w'amazi mu kirere gishyushye, imitingito ishobora kugabanuka vuba, birinda kubangamira uburyo bwo gupima.

Byongeye kandi, nyuma yo gutunganya neza cyane, ishingiro rya granite rishobora kugera ku bugari buhanitse cyane, rigatanga icyerekezo cyizewe cyo gupima neza ibice by'umugozi. Imiterere yaryo ikomeye (ubugari bwa Mohs bwa 6-7) ituma ubuso bw'ibanze bugira ubushobozi bwo kudashira neza. Nubwo ikoreshwa kenshi ahantu hashyushye, ntabwo ishaje cyane, bigatuma igihe cyo gupima cyiyongereye.

Mu rwego rwo gupima imiyoboro y’amashanyarazi hakoreshejwe uburyo bworoshye cyane, ibibazo bya ruswa n’ubudahangarwa biterwa n’ibidukikije bitose ntibishobora kwirengagizwa. Ishingiro rya granite, rifite imiterere karemano yo kurwanya ruswa, imikorere ihamye n’inyungu zidasanzwe, byabaye igisubizo cy’ibanze kuri ibi bibazo. Guhitamo igikoresho gipima imiyoboro y’amashanyarazi gifite ishingiro rya granite bishobora gutuma ikora neza kandi mu buryo burambye mu kirere gitose, gutanga amakuru nyayo kandi yizewe yo gupima, no kurinda iterambere ry’inganda nko gukora imashini n’indege.
