Txhawm rau ua lub tsev ntawm lub hauv paus ruaj khov, koj yuav tsum paub txog kev tiv thaiv lub hauv paus los ntawm kev cuam tshuam los ntawm kev ya raws. Muaj txoj hauv kev los ua koj tus kheej waterproofing pob zeb ua kev siv cov khoom siv pheej yig thiab nyiaj txiag.
Cov Lus Qhia

Kev ua vaj tse yog cov cuab yeej muaj zog tab sis haum hygroscopic. Yog tias nws tsis tiv thaiv los ntawm ya raws, cov txheej txheem ntawm pob zeb rhuav tshem tau qhib. Tom qab nqus dej, nws yuav raug rau cov rog ntawm nyem thiab nthuav tawm, uas yuav tshwm sim thaum khov-yaj ntawm cov kua. Tag nrho cov no yuav ua tsis tau tsuas yog ua kom tawg ntawm cov pob zeb ua ke, tab sis kuj tseem yuav txhim kho qhov kev txhim kho ntawm xeb hlau txuas, nrog kev pab ntawm cov txheej txheem txuas ntawm lub hauv paus.

Lub hauv paus yog tsim tsis yog los ntawm pob zeb ua, tab sis kuj los ntawm cov cib thiab cov tuam tsev ua tau los ntawm lub hauv paus ntawm cov xis mas-xuab zeb sib tov. Ib qho ntawm cov ntaub ntawv no tseem xav tau dej. Txoj kev yooj yim thiab pheej yig tshaj plaws los tiv thaiv lub hauv paus ntawm lub tsev los ntawm ya raws yog muab tshuaj txhuam rau nws nrog nplooj ntawv ntawm cov khoom vov tsev. Niaj hnub no, muaj ntau cov ntaub ntawv niaj hnub ntawm kev muag (rubemast). Tab sis txhua tus ntawm lawv muaj kev hloov siab dua tshiab ntawm cov khoom vov tsev. Kev tiv thaiv dej lub hauv paus, nws raug nquahu kom yuav cov ntawv ntim khoom raws li fiberglass, tsis yog daim duab los qhia. Cov vov ntoo ntawm cov iav fiber ntau muaj lub zog dua thiab tsis ntog.

Cov txheej txheem kev npaj rau dej thaiv lub hauv paus muaj nyob rau hauv kev ntsuas nws cov phab ntsa thiab kev sib khi (yog tias muaj) cov kab nrib pleb thiab nti. Txoj haujlwm no yog ua tiav los ntawm kev siv cov cement-sand mortar. Rau kev nplaum zoo dua ntawm phau ntawv khi thiab nteg cov khoom vov tsev, ib daim tiaj tiaj ntawm cov ntaub nplaum lossis cov nplais pob zeb yog qhov yuav tsum tau ua. Tsis tas li ntawd, tag nrho thaj chaw ntawm lub hauv paus npaj rau pasting nrog cov khoom siv dej tsis zoo yuav tsum tau muab ntxuav ntawm cov xuab zeb thiab av nrog lub txhuam hlau.

Cov txheej txheem loj yog kev tso cov khoom vov tsev. Ua ntej, txheej ntawm kua bitumen lossis mastic yog thov rau pob zeb ua kom pob zeb. Rau qhov no, ob peb pob zeb txuas ntawm phau ntawv yog preheated tshaj hluav taws. Qhov sib ntxiv ntawm kev siv lub tshuab roj (20-25% ntawm tag nrho cov ntim) mus rau bitumen yuav nce nws cov nplaum tsim. Tom ntej no, cov lus kub sib xyaw yog thov rau cov pob zeb ua ke thiab cov ntawv ntawm cov vov tsev yog muab tso rau ntawm nws. Nws cov canvases yuav tsum muab teem saum ib leeg nrog ib qho sib tshooj ntawm tsawg kawg 10 cm. Cov npoo ntawm pob qij txha yuav tsum tau coated nrog kub bitumen thiab glued ua ke. Yog tias thaj chaw muaj cov dej hauv av ntau lossis cov av swampy, nws raug nquahu kom tiv thaiv cov pob zeb ntawm 2-3 txheej ntawm cov khoom siv dej-pleev tshuaj.

Koj kuj tseem tuaj yeem siv lwm txoj hauv kev rau pasting lub hauv paus nrog lub vov tsev muaj kev xav: sov nws cov nplaum sab nrog lub nkev roj lossis tshuab tawg. Cov theem kawg ntawm kev nkag dej ntawm lub hauv paus yog backfilling lub hauv paus qhov nrog av. Txoj kev ua haujlwm no yuav tsum tau ua kom zoo zoo li sai tau thiaj li ua kom tsis muaj kev puas tsuaj ntawm cov ntawv vov tsev nrog pob zeb.
