Kev yuav cov khoom ua si
1) Tus neeg tsim khoom puas muaj daim ntawv tso cai "cement production license" uas yog tso cai los ntawm lub teb chaws "work permit"?
2) Puas yog tus cwj pwm ntawm tus xovtooj no muaj daim ntawv foos tsom iav kuaj lub sam thiaj; seb puas muaj kev tshuaj ntsuam xyuas ntawm lub xeev kev soj ntsuam kev soj ntsuam los yog lub xeev cov chaw lag luam kev sib tsom saibxyuas chaw ua haujlwm.
3) Lub hnab ntim khoom ntim yog lub hnab yas ntim nrog lub plhaub taum pav, tsis muaj kev sib tsoo, tsis muaj teebmeem, tsis meej thiab ua tiav luam ntawv thiab trademark, Net cov ntsiab lus, hnub ntawm kev siv, kev siv ntawm kev siv, cov chaw tsim tshuaj cement. Cov khoom npe thiab lub zog muaj luam tawm ob sab. Tom qab ntawm lub hnab yog luam tawm nrog tus qauv, tus qauv, chav tsev Hoobkas, hnub tim siv ua, lub npe thiab qhov chaw nyob ntawm lub hnab ua lag luam.
4) Uas lub hnab: Lub teb chaws tus txheej txheem qhia tias cov ntsiab lus ntawm cov yas maas yog 50 kg ntawm ib lub hnab, tsis pub tsawg tshaj 98% ntawm tus cim zoo, yog, net ntsiab ntawm txhua lub hnab tsis pub tsawg tshaj 49kg, thiab net cov ntsiab lus ntawm 20 lub hnab uas xaiv cia yuav tsum tsis pub tsawg tshaj 1000 kg. .
Cov cwj pwm
1. Lub peev xwm ntawm cov qhob, thaum nws txawv ntawm tus nqi pib, raug tso cai muab hloov dua siab tshiab;
2. Thaum cov hom thiab qhov hnyav ntawm lub pob zeb uas siv rau hauv cov pob zeb sib txawv ntawm cov theem pib, hloov dua siab tshiab;
3. Rau cov tswvcuab precast uas tau ua rau ntawm qhov chaw, thaum lub lag luam coj los siv tiag, qhov project yuav raug siv los laij cov nqi tsheb thauj mus los ntawm qhov lag luam tawm ntawm qhov chaw.
4. Hauv theem pib, thaum qhov project ntau yog xam los ntawm "m3" los sis "m2", thaum cov khoom siv tshuaj sib txawv sib txawv los ntawm tus nqi them nqi, qhov kev siv nyiaj ntau npaum li cas yuav tsum tau ua lwm yam, thiab lwm tus tsis hloov .
5. Thaum cov khoom siv hluav taws xob muaj zog yog tsim los sib txawv ntawm tus nqi pib, qhov kev hloov ntawm qhov sib txawv ntawm cov hlau thiab cov hlau qhov sib txawv yog sib npaug ntawm cov units.
6. Thaum cov khoom ua cov pob txha ua tau ua tiav, cov nqi ntxiv yog ntxiv.
Nta:
1. Zoo ua tau zoo, kev tsim ua khoom siv ua tau zoo tuaj yeem muaj peev xwm lav tau cov qauv mechanics thiab cov dispersion me me.
2. Qhov kev tsim kho ceev yog ceev, qhov khoom zoo yog qhov zoo, qhov tiav finish, thiab qhov zoo nkauj ntawm cov dej ntshiab yuav tsum tiav, kom lub tsev thiab lub tuam tsev koom thiab sib koom tes.
3, Hoobkas khoom siv hluav taws xob txuag, yog ib qho zoo rau kev tiv thaiv ib puag ncig, txo cov suab hauv chaw siv.
4, kev tua hluav taws zoo.
5. Tag nrho cov kev ua tau zoo ntawm tus qauv yog cov neeg pluag, thiab nws tsis haum rau cov vaj tse uas muaj kev puas siab ntsws seev cev.
