Laser leveling tshuab siv kev txawj ntse thiab cov khoom siv piv
Cov txheej txheem kev tsim txuj ci kev siv thev naus laus zis maj mam ploj mus ntawm tib neeg lub zeem muag. Nyob rau hauv no era ntawm kev loj hlob sai, txoj kev nto laser leveling tshuab tau coj unprecedented txoj kev loj hlob zeem muag rau txoj kev tsim kho. Los ntawm tib neeg-tshuab kev koom tes, txoj kev thev naus laus zis tau mus txog qib siab. . Thaum siv lub tshuab laser leveling, tau kawg, koj yuav tsum muaj qee yam kev ua haujlwm hauv computer, thiab koj yuav tsum muaj qee yam kev txawj me me. Tom qab tag nrho, tag nrho cov ntse neeg hlau laser leveling tshuab tseem tsis tau tawm, thiab 12 xyoo ntawm kev tsim technology yuav piav qhia yuav ua li cas siv nws rau koj. Cov lus qhia rau laser levelers.
Yog tias koj xav tsim txoj kev zoo, ntawm chav kawm, koj yuav tsum tau them sai sai rau kev xaiv cov pob zeb. Cov pob zeb yuav tsum tau tsim, xa los yog tso rau hauv qhov chaw hauv pem teb los ntawm kev lag luam pob zeb ua khoom cog. Pob zeb specifications: C25 ~ C30 qhob, lub zog 28- hnub tsis tsawg tshaj 25MPa, txiav txim siab raws li tus qauv tsim.
Dej-cement ratio: tsis ntau tshaj 0.5, tsis muaj dej ntxiv thaum lub sij hawm pub mis.
Cement: Siv Portland cement zoo tib yam nrog qib tsis tsawg dua 42.5. Aggregate: Cov khoom sib xyaw ua ke zoo yuav tsum tau siv. Crushed granite los yog pebbles yog siv los ua coarse aggregate, thiab qhov siab tshaj plaws txoj kab uas hla tsis ntau tshaj 25mm. Cov nplua aggregate yog cov xuab zeb huv si nrog cov qauv zoo ntawm 2.4-2.7.
Kev sib xyaw ua ke sib piv: cov cement tsis tsawg dua 350Kg / m3. Txhawm rau kom tsis txhob muaj teeb meem zoo, cov xuab zeb yuav tsum tau tswj ntawm 35 feem pua rau 40 feem pua. Pob zeb slump: 14 ± 2cm, siab tshaj 16cm.
Teem sijhawm: Lub sijhawm pib pib yuav tsum tswj tsis pub dhau 3-5 teev.
