ʻike liʻiliʻi | Nā ʻano helu pili pōhaku

ʻO ke kaumaha pōhaku, ka nui, ka uku o ka lawe ʻana｜ Ke ʻano helu helu:
1. Pehea e helu ai i ke kaumaha o ke kinikini

ʻO ka maʻamau, ʻo ka umekaumaha kikoʻī o ke kinikini he 2.5 paona (toni) = mau mika cubic i hoʻonui ʻia e ka ʻumekaumaha kikoʻī.

Pono: E lawe i ka pohaku huinaha 10 knm e ana i ka umekaumaha kiko e oe iho

2. Helu pōhaku a me ke ʻano o ka helu ʻana i ke kumu kūʻai

E hoʻomaopopo mua kākou (ka huaʻōlelo) Pohaku pōhaku, i kapa ʻia hoʻi cube, = lōʻihi * laula * ʻāpana pōhaku kiʻekiʻe, i kapa ʻia hoʻi ka density.

ʻO ka mānoanoa a i ʻole ka umekaumaha kikoʻī o ka granite ma kahi o 2.6-2.9 tons no ka cubic, a ʻo ka mānoanoa a i ʻole ka umekaumaha kikoʻī o ke kinikini ma kahi o 2.5 tons per cubic.

E helu i ke kaumaha pōhaku: ka nui pōhaku a i ʻole cubic * mānoanoa a i ʻole ʻumekaumaha kikoʻī, ʻo ia hoʻi: ka lōʻihi * laula * mānoanoa * ʻumekaumaha kikoʻī = kaumaha pōhaku, inā makemake ʻoe e ʻike i ke kumukūʻai o kēlā me kēia pōhaku (mai ke kumu o ke kumu - kahi o ka hoʻohana).

ʻO ke ʻano helu helu:

Length * laula * kiʻekiʻe * like * tona / kumu = kumu kūʻai o kēlā me kēia pōhaku.

3. Ka helu ʻana i ka nui pōhaku, ka mānoanoa a me ke kaumaha

(1) Heluhelu huahana wale nō:

1 tālena = 303×303㎜;

1 ping = 36 ping; 1 mika huinaha (㎡) = 10.89 ping = 0.3025 ping

Ka helu kālena: lōʻihi (mika) × laula (mika) × 10.89 = kālena

E laʻa:

Me ka lōʻihi o 3.24 mika a me ka laula o 5.62 mika, ua helu ʻia kāna huahana talena penei → 3.24 × 5.62 × 10.89 = 198.294 talena = 5.508 ping

(2) Ka helu mānoanoa:

1. Ua helu ʻia i ke kenimika (㎝): 1 kenimika (㎝) = 10 mm (㎜) = 0.01 mika (m)

(1) Ka mānoanoa maʻamau o ka granite: 15mm, 19mm, 25mm, 30mm, 50mm

(2) Ka mānoanoa maʻamau o ke kinikini: 20mm, 30mm, 40mm

(3) Ka mānoanoa maʻamau o ka pōhaku Roma a me ka pōhaku i lawe ʻia mai: 12mm, 19mm

2. Helu helu:

1 kiko = 1/8 ʻīniha = 3.2mm (ʻike mau ʻia ʻo 3mm)

4 mau helu = 4/8 iniha = 12.8mm (ʻike mau ʻia ʻo 12mm)

5 helu = 5/8 iniha = 16㎜ (ʻike mau ʻia ʻo 15㎜)

6 mau helu = 6/8 iniha = 19.2mm (ʻike maʻamau ʻo 19mm)

(3) Ka helu kaumaha:

1. Granite a me ke kinikini: 5 helu = 4.5㎏; 6 helu = 5㎏; 3㎝ = 7.5㎏ 2.

Pōhaku Roma: 4 helu = 2.8㎏; 6 helu = 4.4㎏

4. Column pohaku, special-shaped stone Stone kolamu mea maoli maʻamau, a okoa ke kinona, aohe kumu e kuhikuhi pololei.

ʻO ke kumu kūʻai ʻāpana = kumu kūʻai + loaʻa = kumu kūʻai waiwai + kumukūʻai hana + loaʻa kālā nui

(1). He maʻalahi ke kumukūʻai o nā mea waiwai, a he ʻokoʻa loa ke kumukūʻai hana ma muli o ka paʻakikī like ʻole o ka hana ʻana i ke ʻano o ka cylinder pōhaku, nā ʻano mea like ʻole i hoʻohana ʻia, a me nā mea hana, ka hiki ke hana, a me ka ʻike o kēlā me kēia hale hana, no laila aia. ʻAʻohe ala e helu pono ai. .

(2). No kekahi mau pahu pōhaku maʻamau a maʻalahi, maʻalahi ke helu ma ka ʻili. E mālama pono i ka nui a me ke kala i makemake ʻia e nā mea kūʻai aku. Ma hope o nā mea a pau, ʻoi aku ka nui o ka lōʻihi o nā cylinders pōhaku, no laila paʻakikī ka loaʻa ʻana o nā poloka i kūpono i ka nui, no laila ʻaʻole kiʻekiʻe ke kumukūʻai. ʻAʻole i hoʻonohonoho ʻia e like me ke kumu kūʻai maʻamau a me ke kumu kūʻai poloka. Akā e like me ka nui kikoʻī, e hoʻohana ʻia ka nui ma hope.

(3). No laila, ʻo ke ala pololei ua hana ʻoe i ka hana ʻana a hiki ke helu wale ʻia ma hope o ka lōʻihi o ka hōʻiliʻili ʻike. ʻO ka mea maʻamau, e hoʻohana nā kumu akamai i ke ʻano empirical e helu ai. Laʻana: Ua loaʻa i kā mākou hui kekahi mau kolamu i paʻakikī loa i ka hana ma mua, a ua manaʻo ka hale hana hana i ke kumukūʻai ma muli o ka ʻike i hala. Ua hana kēia hale hana hana i nā ʻano a me nā kolamu kūikawā no nā makahiki he ʻumi. Eia naʻe, no ka mea ʻoi aku ka paʻakikī o ka hana maoli ma mua o ka mea i manaʻo ʻia, ua hoʻonui ʻia ke kumukūʻai e 50% (ʻo ka hale hana ponoʻī i ʻōlelo ai), akā ma muli o ke kuhi hewa ʻana o ka hale hana, ua mau ke kumukūʻai me ke kumu kūʻai mua. A i ʻole, inā i manaʻo ʻia e kā mākou hui, pau ia, a nalowale.

(4). Inā he ʻoihana kālepa ʻoe, ʻoi aku ka maikaʻi o ka ʻōlelo ʻole no nā pōhaku ʻano kūikawā e like me nā kolamu pōhaku, ʻoi aku ka paʻakikī o ka hana ʻana, a i ʻole he maʻalahi ke hana hewa i ka manaʻo. ʻOi aku ka maikaʻi o ka haʻi ʻana i ka palekana e pili ana i ke kumukūʻai hale hana.
