9、標(biāo)識。3.4機(jī)具準(zhǔn)備清理基層用：小平鏟、掃帚、鋼絲刷。質(zhì)量檢查用：鋼卷尺(50m、30m)。涂基層處理劑：流動刷、油漆刷。容器：小油桶。裁剪工具：剪刀。彈線用：小白線、彩色粉筆。熱熔施工：噴燈。壓實卷材用：鐵管滾(φ200100mm)、壓板(小型)3.5進(jìn)度計劃本防水施工要配合基礎(chǔ)土方、基礎(chǔ)底板和地下室外墻結(jié)構(gòu)、回填土施工進(jìn)行。詳見附圖。四、主要施工方法四、主要施工方法底板卷材防水采用外防內(nèi)貼，底層卷材熱熔點粘，上層卷材熱熔滿粘。地下室

10、外墻卷材防水采用外防外貼，卷材均為熱熔滿粘。剛性防水混凝土采用商品混凝土，泵送施工，高頻振搗棒振搗。4.14.1底板卷材防水底板卷材防水4.1.1工藝流程墊層上抹砂漿找平層→基層清理→涂刷冷底子油→做防水附加層→鋪貼底板及保護(hù)墻墻底部防水層→澆筑細(xì)石砼保護(hù)層。4.1.2找平層墊層上用1：3水泥砂漿找平層。4.1.3基層處理底板墊層施工時，表面一次磨平、壓光達(dá)到防水基層的效果。在集水井、電梯井邊等陰陽角處，均用1：3水泥砂漿做成半徑為50
