Kev txiav txim siab tseem ceeb rau Stamped Decorative Concrete Construction

Exposed aggregate pervious pob zeb yog ib qho khoom siv tshiab uas sib xyaw ua kom zoo nkauj nrog cov txiaj ntsig ib puag ncig. Nws yog tshwj xeeb tshaj yog muaj nuj nqis rau nws permeability, tso cai rau dej los ntawm thiab txo cov dej ntws, yog li txhawb nqa dej hauv av recharge. Txawm li cas los xij, ua kom tau raws li qhov xav tau thiab kev ua tau zoo yuav tsum tau ua tib zoo saib xyuas thaum tsim kho. Nov yog yam tseem ceeb uas yuav tsum tsom mus rau:

1. Kev xaiv cov khoom siv

Xaiv cov ntaub ntawv zoo yog qhov tseem ceeb. Cov aggregates yuav tsum huv si, zoo-qib, thiab qhov loj me kom ntseeg tau tias muaj kev sib raug zoo thiab muaj qhov chaw txaus rau permeability. Cement thiab admixtures yuav tsum tau sib xws kom tswj tau qhov xav tau kev ua haujlwm thiab lub zog.

2. Mix Design

Qhov sib tov tsim yuav tsum sib npaug zog thiab permeability. Cement paste ntau dhau tuaj yeem txhaws qhov chaw tsis muaj zog, txo cov permeability, thaum me me tuaj yeem ua rau cov pob zeb tsis muaj zog. Ib qho kev sib xyaw ua ke suav nrog qis dej-cement piv thiab suav nrog superplasticizers txhawm rau txhim kho kev ua haujlwm tsis muaj kev cuam tshuam lub zog.

3. Kev npaj subgrade

Ib qho kev npaj subgrade kom zoo yog qhov tseem ceeb rau cov pob zeb pervious. Nws yuav tsum tau ruaj khov thiab zoo-compacted los txhawb cov pob zeb ua pob zeb thiab ua kom yooj yim rau cov kua dej. Ib txheej txheej subbase tsim kom zoo, feem ntau muaj cov pob zeb huv si, pab tswj cov dej nkag los ntawm cov pob zeb.

4. Kev tso chaw thiab kev sib dhos

Qhov chaw yuav tsum tau ua kom sai kom tsis txhob teeb tsa ua ntej ua tiav. Kev siv cov vibratory screeds thiab cov menyuam compactors yog pom zoo los xyuas kom meej txawm tias tis thiab compaction kom zoo. Over-compaction tuaj yeem kaw qhov pores, thaum qis-compaction tuaj yeem ua rau thaj chaw tsis muaj zog.

5. Ntog tawm

Kev nthuav tawm cov aggregate xav tau lub sijhawm meej. Tom qab muab tso rau thiab pib qhov chaw, qhov chaw muab tshuaj txhuam yuav tsum tau muab tshem tawm los ntawm kev ntxuav dej los yog retarders tom qab txhuam hniav. Lub sij hawm tsim nyog yog qhov tseem ceeb kom tsis txhob muaj qhov tshwm sim ntxov los yog ncua sij hawm, uas tuaj yeem cuam tshuam rau kev zoo nkauj thiab kev ncaj ncees ntawm qhov chaw.

6. Khoov

Curing pervious qhob yog me ntsis txawv ntawm cov pa ua vaj tse. Nws yuav tsum tau ua kom lub ntsej muag ntub rau lub sijhawm ntev kom tiv thaiv kom qhuav sai, uas tuaj yeem ua rau tawg. Npog nrog cov ntawv yas los yog siv cov tshuaj tua kab mob tuaj yeem pab tswj cov qib noo noo.

7. Kev Tswj Xyuas Zoo

Kev tswj xyuas qhov zoo tsis tu ncua yog qhov tseem ceeb. Kev ntsuam xyuas permeability, lub zog, thiab kev sib xyaw ua ke kom ntseeg tau tias cov pob zeb ua tau raws li qhov xav tau tshwj xeeb. Txhua qhov sib txawv yuav tsum tau hais tam sim kom tsis txhob muaj teeb meem mus ntev.

Xaus

Kev tsim ua tiav ntawm kev sib xyaw ua ke pervious pob zeb yuav tsum tau ua tib zoo saib xyuas kom meej los ntawm kev xaiv cov khoom mus txog rau kev kho. Los ntawm kev tsom mus rau cov kev xav tseem ceeb no, cov neeg cog lus tuaj yeem ua kom ruaj khov, ua haujlwm zoo, thiab ua kom zoo nkauj zoo nkauj uas ua rau muaj txiaj ntsig zoo rau kev tsim kho kom ruaj khov.
