Waterproof txheej tsim thiab kev kho kom ntxaws

ⅠDkev ua lag luam

1. Sab hauv thiab sab nrauv: kev sib txuas ntawm av thiab phab ntsa yuav tsum tau plastered rau hauv ib qho arc nrog lub vojvoog ntawm 20mm.

2. Cov hauv paus hniav ntawm cov yeeb nkab: Tom qab cov yeeb nkab hauv paus ntawm phab ntsa yog positioned, hauv pem teb yog nruj nreem thaiv nrog cov cement mortar, thiab qhov chaw nyob ib ncig ntawm cov yeeb nkab hauv paus txuas nrog hauv av yog plastered rau hauv daim duab-yim duab nrog cov cement mortar.

3. Cov kav dej thiab cov khoom sib txuas los ntawm cov phab ntsa yuav tsum tau muab ntsia kom ruaj, thiab cov pob qij txha yuav tsum nruj.

Ⅱ Waterproofing txheej tsim:

1. Cov kev xav tau ntawm lub hauv paus nto ua ntej kev tsim kho: nws yuav tsum tiaj tus, thiab yuav tsum tsis txhob muaj qhov tsis xws luag xws li gouges thiab grooves.

2. Ua ntej kev tsim kho, phab ntsa thiab hauv av yuav tsum tau ntub dej kom tshem tawm cov huab cua hauv lub qhov phab ntsa, kom cov phab ntsa ntawm phab ntsa yog denser thiab qhov saum npoo yog permeable.

3. Thaum sib tov cov hmoov thiab cov khoom ua kua, nws yog ib qho tsim nyog yuav tsum tau siv lub laum hluav taws xob.Tom qab nplawm ntawm qhov ceev tsis tu ncua, tso nws rau 3-5 feeb;Yog hais tias nws yog manually stirred, nws yuav tsum tau stirred li 10 feeb, thiab ces muab tso rau 10 feeb ua ntej siv.

4. Thaum siv, yog tias muaj npuas hauv cov slurry, cov npuas yuav tsum tau txhuam, thiab yuav tsum tsis muaj npuas.

5. Nco ntsoov: Kev txhuam hniav, koj tsuas yog yuav tsum txhuam hauv ib qho kev taw qhia hauv ib qho kev hla, thiab nyob rau sab nraud rau qhov thib ob hla.

6. Lub sijhawm ntawm kev txhuam hniav thawj zaug thiab zaum thib ob yog qhov zoo dua li 4-8 teev.

7. Nws tsis yooj yim rau txhuam cov thickness ntawm lub façade, thiab nws tuaj yeem txhuam ob peb zaug.Thaum txhuam hniav, yuav muaj qhov ntev li ntawm 1.2-1.5 hli, yog li nws yuav tsum tau txhuam ntau zaus kom nws cov compactness thiab sau cov void ceev.

8. Xyuas seb cov dej tsis zoo puas tsim nyog

Tom qab ua tiav txoj haujlwm ua dej tsis zoo, kaw lub qhov rooj thiab qhov hluav taws xob dej, sau cov chav dej hauv pem teb nrog dej rau ib theem, thiab kos nws.Yog tias cov kua dej tsis poob qis hauv 24 teev thiab lub ru tsev ntawm lub hauv paus tsis xau, ces cov dej tsis zoo yog tsim nyog.Yog tias qhov kev lees txais ua tsis tiav, tag nrho cov dej tsis huv yuav tsum tau rov ua dua ua ntej kev lees txais.Tom qab paub tseeb tias tsis muaj qhov xau, rov tso cov vuas hauv pem teb.
