Thaum peb npaj yuav ua hauv pem teb hauv chav nres tsheb, peb xav paub seb qhov twg ntawm ntau qhov kev paub zoo rau lawv qhov kev npaj yuav tsum peb xaiv. Txhawm rau txiav txim siab txog qhov kev xaiv, koj yuav tsum ntsuas tag nrho cov txiaj ntsig thiab qhov tsis zoo ntawm kev cuam tshuam rau txhua hom kev pab them nqi tshwj xeeb. Feem ntau, ntau tus xaiv rau lawv ua dab tsi hauv chav nres tsheb hauv pem teb ntawm pob zeb. Nyeem ntxiv txog qhov no hauv kab lus no.
Yuav ua kom cov pob zeb hauv pem teb hauv chav nres tsheb, koj yuav tsum xub ua kom tiav kev npaj ntawm lub hauv paus. Cov txheej txheem no yuav tsum tau muab kev saib xyuas tshwj xeeb.

- Txhawm rau txhim kho cov pob zeb hauv pem teb hauv lub tsev nres tsheb ntawm qhov qub, koj yuav tsum npaj kom zoo. Muab tag nrho cov kab nrib pleb, yog tias muaj, nrog kev sib xyaw ntawm cov xuab zeb thiab cov cement. Cov cheeb tsam uas kho tsis tau yuav tsum tau ua kom tiavmuab nws sib cais thiab ces refill nws. Qhov siab sib txawv yuav tsum tau muab tshem tawm siv lub tshuab milling tshwj xeeb, thiab tsuas yog tom qab ntawd pib nrog nchuav hauv pem teb.
- Thaum lub hauv paus tau muab tso rau hauv av, ua ntej koj pib nchuav, koj yuav tsum ua tib zoo tamp cov av kom tom qab ntawd tsis muaj qhov qis dua. Tom qab ntawd, koj yuav tsum tau ua cov xuab zeb cushion thiab kuj compact nws zoo. Lub thickness ntawm lub hauv ncoo nws tus kheej nyob ntawm ntau yam: theem ntawm lub perch, lub degree ntawm khov thiab zoo li cas ntawm lub hauv paus.
Koj kuj yuav tsum nco ntsoov tiv thaiv cov pob zeb hauv pem teb los ntawm kev ya raws, rau qhov no koj yuav tsum siv tag nrho cov ntaub ntawv pov thawj bitumen-based waterproofing, polymer membrane los yog zaj duab xis zoo tib yam.

pob zeb pem teb
hauv qhov chaw nres tsheb yog tsis yooj yim sua yam tsis muaj kev txhawb nqa. Rau qhov no, ib tug tshwj xeeb xaim nrog ib txoj kab uas hla ntawm 5 hli yog siv, thiab qhov luaj li cas ntawm lub reinforcement hlwb yog 150150 hli. Yog hais tias lub txheej yog raug rau ib tug loj heev mechanical load, ces lub thickness ntawm cov pob zeb hauv pem teb nyob rau hauv lub chav nres tsheb yuav tsum ntau dua. Tom qab ntawd nws yog ib qho tsim nyog los tsim ib lub tawb ntxiv los ntawm kev txhawb nqa nrog ib txoj kab uas hla ntawm 0.8-1.6 cm, los yog los ntawm kev txhawb nqa mesh. Qhov no yoglub sijhawm tseem ceeb. Cov pob zeb hauv pem teb hauv chav nres tsheb pib nchuav tsuas yog tom qab txhua qhov kev npaj ua tiav tiav
works: compacting av, nteg waterproofing, npaj cov formwork thiab txhim kho lub reinforcing tawb. Kev sau tuaj yeem ua tiav ob qho tib si manually thiab nrog kev pab los ntawm lub pob zeb sib tov tsheb. Yog hais tias nws muaj peev xwm tsav mus rau qhov chaw ntawm pouring, ces lub unloading ntawm pob zeb yog nqa tawm ncaj qha los ntawm nws mus rau lub twb npaj puag. Yog tias nws tsis tuaj yeem tsav tsheb, los yog lub filling yog nqa tawm ntawm ib lub toj, ces nyob rau hauv cov ntaub ntawv no nws yog tsim nyog los siv lub pob zeb twj tso kua mis. Tom qab nchuav, koj yuav tsum tau ua cov pob zeb hauv pem teb hauv chav nres tsheb uas siv cov cuab yeej xws li vibrating screed. Txhawm rau ua qhov no, teeb tsa cov lus qhia ntawm xoom thiab theem qhov sib xyaw ua ke raws cov lus qhia.
Tom qab ua kom tiav, peb tos kom qhuav kom tiav, thiab hauv pem teb yog npaj.
