E pili ana i ka mānoanoa o ka pōhaku
Aia kekahi ʻano ʻano like ʻole i ka ʻoihana pōhaku: ʻo ka mānoanoa o nā papa nui e mānoanoa a lahilahi, mai 20mm ka mānoanoa i ka makahiki 1990 a hiki i ka 15mm i kēia manawa, a hiki i ka lahilahi e like me 12mm.
Manaʻo ka poʻe he nui ʻole ka mānoanoa o ka pā i ka maikaʻi o ka pōhaku.
No laila, i ke koho ʻana i kahi lau, ʻaʻole i hoʻonohonoho ʻia ka mānoanoa o ka lau ma ke ʻano he kānana.
ʻAʻole pili maoli ka mānoanoa o ka papa i ka maikaʻi o nā huahana pōhaku?
a.No ke aha e haki a haki ai ka papa papahele i hoʻokomo ʻia?
b.No ke aha i hoʻopōʻino ʻia ai ka papa i kau ʻia ma ka pā i ka wā i pā iki ʻia e ka ikaika o waho?
c.No ke aha i nalowale ai kahi ʻāpana mai ka ʻaoʻao mua o ke alapiʻi ma hope o ka hoʻohana ʻana no kekahi manawa?
d.No ke aha i ʻike pinepine ai nā pōhaku lepo i hoʻokomo ʻia ma nā ʻāpana i ka pōʻino?
ʻO ka mana o ka mānoanoa pōhaku i ka huahana
Ua lilo ia i mea maʻamau a me nā mea kūʻai aku i nā mea kūʻai pōhaku e kūʻai aku i nā ʻāpana lahilahi a lahilahi.
ʻO keʻano,ʻo nā mea kālepa pōhaku me nā mea maikaʻi a me nā kumukūʻai pipiʻi eʻoi aku ka makemake e hana i ka mānoanoa o nā papa nui.
Ma muli o ka mānoanoa nui o ka pōhaku, ua piʻi ke kumukūʻai o nā papa nui, a manaʻo nā mea kūʻai aku he kiʻekiʻe ke kumukūʻai ke koho lākou.
ʻO ka hoʻoemi ʻana i ka mānoanoa o ka papa nui e hiki ke hoʻonā i kēia kūʻē, a ua ʻae nā ʻaoʻao ʻelua.
ʻO ka hopena e pili pono ana ka ikaika compressive o ka pōhaku i ka mānoanoa o ka pā:
Ke ʻoi aku ka lahilahi o ka mānoanoa o ka pā, ʻoi aku ka nāwaliwali o ka paʻa o ka pā, a ʻoi aku ka pōʻino o ka pā;
ʻO ka ʻoi aku ka mānoanoa o ka papa, ʻoi aku ka nui o kona kūʻē ʻana i ka paʻi ʻana, a ʻoi aku ka liʻiliʻi o ka haki ʻana o ka papa.
ʻO nā pōʻino o ka mānoanoa Pōhaku he lahilahi loa
① Māwaliwali
Ua piha ka nui o ke kinikini maoli i nā māwae, a ua maʻalahi ka haʻihaʻi ʻana o ka pā 20mm mānoanoa a pohō, waiho ʻia ka pā nona ka mānoanoa ma lalo o 20mm.
No laila: ʻo ka hopena maopopo loa o ka lawa ʻole o ka mānoanoa o ka papa, ʻo ia ka maʻalahi o ka haki ʻana a me ka pōʻino o ka papa.
② Hiki ke ʻike ʻia nā lepa
Inā lahilahi ka papa, hiki i ke kala o ka sima a me nā mea hoʻopili ʻē aʻe ke hoʻohuli i ke koko, e pili ana i ka helehelena.
ʻIke loa kēia ʻano no ka pōhaku keʻokeʻo, ka pōhaku like me ka jade a me nā pōhaku ʻulaʻula ʻē aʻe.
ʻOi aku ka maʻalahi o nā papa lahilahi ma mua o nā papa mānoanoa: maʻalahi ke hoʻololi ʻana, warp, a me ka hakahaka.
