Boima ba lejoe, molumo, tefiso ea lipalangoang｜ Mokhoa oa ho bala:
1. Mokhoa oa ho bala boima ba 'mabole
Hangata matla a khoheli a 'mabole ke boima ba 2.5 (lithane) = cubic metres e atisoa ke matla a khoheli a itseng.
Nepahetse: Nka lejoe la lisekoere tsa 10 cm ho lekanya matla a khoheli a itseng u le mong
2. Palo ea boima ba majoe le mokhoa oa ho bala litšenyehelo tsa lipalangoang
A re utloisiseng pele (lereo) Bophahamo ba lejoe, le boetse le bitsoa cube, = bolelele * bophara * bophahamo ba lejoe le lekanang, le boetse le bitsoa density.
Boima kapa matla a khoheli a itseng a granite a ka ba lithane tse 2,6-2,9 ka cubic, 'me boima ba 'mabole kapa matla a khoheli a itseng ke lithane tse 2,5 ka cubic.
Bala boima ba lejoe: boima ba lejoe kapa cubic * density kapa khoheli e itseng, ke hore: bolelele * bophara * botenya * matla a khoheli = boima ba lejoe, haeba u batla ho tseba theko ea lejoe le leng le le leng (ho tloha mohloling oa mohloli - sebaka. tsa tshebediso).
Mokhoa oa ho bala ke:
Bolelele * bophara * bophahamo * tekanyo * lithane / theko = theko ea lejoe ka leng.
3. Palo ea bophahamo ba lejoe, botenya le boima
(1) Ke palo ea sehlahisoa feela:
1 talenta = 303×303㎜;
1 ping = 36 ping; 1 square meter (㎡) = 10.89 ping = 0.3025 ping
Palo ea litalenta: bolelele (mitha) × bophara (mithara) × 10.89 = talenta
Mohlala:
Ka bolelele ba limithara tse 3.24 le bophara ba limithara tse 5.62, sehlahisoa sa eona sa talenta se baloa ka tsela e latelang → 3.24 × 5.62 × 10.89 = 198.294 talenta = 5.508 ping
(2) Palo ea botenya:
1. E ballotsoe ka lisentimitara (㎝): 1 centimeter (㎝) = 10 mm (㎜) = 0.01 limithara (m)
(1) botenya bo tloaelehileng ba granite: 15mm, 19mm, 25mm, 30mm, 50mm
(2) Botenya bo tloaelehileng ba 'mabole: 20mm, 30mm, 40mm
(3) Botenya bo tloaelehileng ba lejoe la Roma le lejoe le tsoang kantle ho naha: 12mm, 19mm
2. E baloa ka lintlha:
1 ntlha = 1/8 inch = 3.2mm (e tsejoang hangata e le 3mm)
Lintlha tse 4 = 4/8 inch = 12.8mm (e tsejoang hangata e le 12mm)
Lintlha tse 5 = 5/8 inch = 16㎜ (e tsejoang hangata e le 15㎜)
Lintlha tse 6 = 6/8 inch = 19.2mm (e tsejoang hangata e le 19mm)
(3) Palo ea boima ba 'mele:
1. Granite le marble: lintlha tse 5 = 4.5㎏; Lintlha tse 6 = 5㎏; 3㎝ = 7.5㎏ 2.
Lejoe la Roma: lintlha tse 4 = 2.8㎏; Lintlha tse 6 = 4.4㎏
4. Lejoe la kholomo, lejoe le nang le sebōpeho se khethehileng Lejoe la majoe le hlile le le akaretsang haholo, 'me sebopeho se fapane, ha ho na mokhoa oa ho qotsa ka ho toba.
Ha e le hantle theko ea yuniti = litšenyehelo + phaello = litšenyehelo tsa thepa + litšenyehelo tsa ho sebetsa + phaello e felletseng
(1). Litsenyehelo tsa thepa li bonolo ho li bala, 'me litšenyehelo tsa ho sebetsa li fapane haholo ka lebaka la bothata bo fapaneng ba ho sebetsana le sebōpeho sa moqomo oa lejoe, lisebelisoa tse fapaneng tse sebelisoang, le lisebelisoa, bokhoni ba ho sebetsa, le tsebo ea fektheri e' ngoe le e 'ngoe. ha se mokhoa oa ho e bala ka nepo. .
(2). Bakeng sa li-cylinders tse tloaelehileng le tse bonolo tsa majoe, ho bonolo ho bala holim'a metsi. Etsa bonnete ba hore u ela hloko boholo le 'mala o hlokoang ke bareki. Ha e le hantle, bolelele ba li-cylinders tsa majoe bo batla bo le boholo, kahoo ho thata ho fumana li-blocks tse finyellang boholo, kahoo theko ha e phahame. Ha e behiloe ho latela theko e tloaelehileng ea poleiti le theko ea block. Empa ho latela boholo bo itseng, tse ngata li tla sebelisoa hamorao.
(3). Ka hona, mokhoa o tobileng ke hore o entse ts'ebetso mme o ka baloa feela ka mor'a nako e telele ea ho bokella phihlelo. Ka kakaretso, matichere a nang le boiphihlelo a tla sebelisa mokhoa oa ho bala. Mohlala: Khamphani ea rona e ne e e-na le litšiea tseo ho neng ho le thata haholo ho li sebetsa pele, 'me feme ea ho lokisa e ile ea hakanyetsa litšenyehelo ho latela phihlelo ea nako e fetileng. Feme ena e sebetsang e entse libopeho le litšiea tse khethehileng ka lilemo tse fetang leshome. Leha ho le joalo, hobane tlhahiso ea sebele e thata ho feta kamoo ho neng ho nahanoa kateng, litšenyehelo li eketsehile ka 50% (fektheri ka boeona e boletse), empa ka lebaka la phoso ea fektheri ka boeona, theko e lula e tšoana le theko ea pele. Ho seng joalo, haeba e hakanngoa ke k'hamphani ea rona, e tla be e felile, 'me e tla lahleha.
(4). Haeba u le k'hamphani ea khoebo, ho molemo hore u se ke ua qotsa bakeng sa majoe a bōpehileng joaloka litšiea tsa majoe, haholo-holo tseo ho leng thata ho li sebetsana, kapa ho bonolo ho etsa liphoso ka tekanyo. Ho molemo ho qotsa ts'ireletso ho latela theko ea feme.
