二层露天平台防水工程施工工艺

.................第二层露天平台防水工程施工工艺，程序须知原楼板填缝，各坑洼处抹平。（作用：节约防水资料）地脚线地址，开凿凹进2cm。（柔性防水资料，必定用砂浆覆盖）地面除灰尘，沙粒。并且楼面须干燥一天。（增加防水的附着性）采用有弹性的沥青油资料，滚涂仔细不留死角。（弹性须适应南非约翰内斯堡的昼夜巨大温差，不发生脆裂）在沥青油防水层上，覆盖纤维布。在纤维布上再重复滚涂沥青资料一次。（增加强度和防水性能）覆盖塑料薄膜膜后。做7天闭水试验。不漏水，成功防漏后，进入下一步工序。（及时发现并整改，减少..................................更大的损失）膜上铺设钢丝网，轻拿轻放，保护好防水层。用砂浆做走水坡面面。保证有5cm落差。落水口为两110管。（不积水，雨水流走快速）干燥后，在走水坡面上涂刚性聚合物防水剂。（防范砂浆层存水。注意：室内浴室防水只需此道工序）铺设地砖，留0.5cm砖缝。用膨胀性水泥填缝。..................................Thefirstflooropenplatformwaterproofprojectconstructionprocess,programinstructions1originalfloorseamfilling,eachplacecertainlysomepits.Function:save(waterproofmaterial),2theanchorlineposition,digging2cminstead.Flexiblewaterproofingmaterials,must(withmortar)3groundremovedust,sand.Andthefloorsshallbedry.(theadhesion)increasedwaterproof4usingelasticmaterial,coatingofasphaltoilnotcarefully.Johannesburg,SouthAfrica(elasticmustadapttothehugedifferencedoesnotoccurembrittlement),5oilinasphaltwaterproof,coveringfibercloth.6infiberclothrepeatrollasphaltmaterial.(toincreasetheintensityandwaterproofproperties),7coverplasticmembrane.Do7daysshuttingwatertest.Don'tslack,leakproof,afterthesuccessfulenteringthenextprocedure.Timelydiscoveryandrectification,(reductiongreaterloss),8thelayingofsteelwire,membranegentlywithgoodprotectionofwaterproof.Doeverythingwithmortardonslope.Ensure5cm
