三、施工方法：
1.找坡(po)層施工(gong)：先按設(she)計坡(po)度(du)及流(liu)水(shui)方向，用砂漿(jiang)打點定位，確保坡(po)度(du)、厚度(du)正(zheng)(zheng)確;鋪設(she)水(shui)泥爐渣找坡(po)，用平板振動器(qi)壓(ya)實適(shi)當，表(biao)面(mian)平整，找坡(po)正(zheng)(zheng)確;找坡(po)層完工(gong)后(hou)，應用彩條布覆蓋，以防(fang)浸水(shui)和破壞;鋪設(she)找坡(po)層時，應按設(she)計規定埋設(she)好排(pai)氣(qi)管（采用Φ50排(pai)氣(qi)管排(pai)氣(qi)，每36m2.設(she)置一個出氣(qi)口排(pai)氣(qi)管出屋面(mian)不(bu)小于300詳見后(hou)附）。
2.保溫層施工：基層應(ying)平整(zheng)、干凈、干燥；擠(ji)塑板(ban)(ban)(ban)(ban)的(de)鋪貼(tie)方式(shi)采用(yong)干鋪；擠(ji)塑板(ban)(ban)(ban)(ban)不(bu)(bu)應(ying)破碎、缺棱(leng)角，鋪設時遇有缺棱(leng)掉角、破碎不(bu)(bu)齊的(de)，應(ying)鋸平拼(pin)接使用(yong);板(ban)(ban)(ban)(ban)與板(ban)(ban)(ban)(ban)間之間要錯縫(feng)、擠(ji)緊，不(bu)(bu)得(de)有縫(feng)隙(xi)。若因擠(ji)塑板(ban)(ban)(ban)(ban)裁剪(jian)不(bu)(bu)方正或裁剪(jian)不(bu)(bu)直而(er)形(xing)成縫(feng)隙(xi)，應(ying)用(yong)擠(ji)塑板(ban)(ban)(ban)(ban)條塞入并打磨平。
3.水泥砂(sha)(sha)漿(jiang)找平(ping)(ping)層(ceng)施工：水泥砂(sha)(sha)漿(jiang)要求：嚴格控制(zhi)配合比，使用(yong)清凈中(zhong)砂(sha)(sha)并過(guo)5mm孔(kong)(kong)篩，含泥量不大(da)于3%;做(zuo)好防水基層(ceng)的處理，板(ban)面(mian)上(shang)的垃圾、雜物、硬(ying)化(hua)的砂(sha)(sha)漿(jiang)塊等必須請除干凈，墻(qiang)上(shang)四周必須彈(dan)出(chu)(chu)水平(ping)(ping)標高控制(zhi)線(xian)（50線(xian)）。孔(kong)(kong)洞(dong)(dong)、管線(xian)應(ying)(ying)事(shi)前預埋、預留，嚴禁(jin)事(shi)后(hou)打洞(dong)(dong); 施工前應(ying)(ying)在底層(ceng)先刷一道(dao)素水泥漿(jiang)，找平(ping)(ping)層(ceng)應(ying)(ying)粘結牢固(gu)，沒有松動、起(qi)砂(sha)(sha)、起(qi)皮等現象，表(biao)面(mian)平(ping)(ping)整度≤5mm； 找平(ping)(ping)層(ceng)應(ying)(ying)設(she)置(zhi)30寬分隔縫，間距(ju)不大(da)于6m×6m； 在女(nv)兒墻(qiang)、管道(dao)出(chu)(chu)屋面(mian)處均做(zuo)成半(ban)徑(jing)不小于10~15cm的圓(yuan)角；注意(yi)氣(qi)候變化(hua)，如(ru)氣(qi)溫在0℃以下或終凝前可能下雨時(shi)，不宜施工。如(ru)必須施工時(shi)，應(ying)(ying)有技術措施，保證(zheng)找平(ping)(ping)層(ceng)質(zhi)量。
4.防水層(ceng)施工(gong)(gong)：冷(leng)底子(zi)油(you)的(de)涂(tu)刷，基(ji)層(ceng)處(chu)理劑的(de)涂(tu)刷要(yao)薄而(er)均(jun)勻，不(bu)得有(you)空(kong)白、麻點、氣泡(pao)；涂(tu)刷時間(jian)宜(yi)在(zai)鋪(pu)(pu)貼(tie)油(you)氈前1-2h進行，使油(you)層(ceng)干(gan)燥(zao)而(er)不(bu)粘灰塵；基(ji)層(ceng)處(chu)理劑涂(tu)刷后(hou)宜(yi)在(zai)當天鋪(pu)(pu)完防水層(ceng)，但也要(yao)根據具體情(qing)況(kuang)靈(ling)活確定。如多雨季(ji)節、工(gong)(gong)期緊(jin)張的(de)情(qing)況(kuang)下，可先涂(tu)好全部基(ji)層(ceng)處(chu)理劑后(hou)再鋪(pu)(pu)貼(tie)卷材，這(zhe)樣可以防止雨水滲入找平(ping)層(ceng)，而(er)且(qie)基(ji)層(ceng)處(chu)理劑干(gan)燥(zao)后(hou)的(de)表面(mian)水分蒸發較快；一(yi)次涂(tu)的(de)面(mian)積，根據基(ji)層(ceng)處(chu)理劑干(gan)燥(zao)時間(jian)的(de)長短和施工(gong)(gong)進度快慢確定。面(mian)積過大，來不(bu)急鋪(pu)(pu)貼(tie)卷材，時間(jian)過長易(yi)被風沙塵土(tu)污染或(huo)露水打濕；面(mian)積過小，影響下道工(gong)(gong)序的(de)施工(gong)(gong)，拖延工(gong)(gong)期。
5.防(fang)水卷(juan)材(cai)鋪(pu)貼(tie)卷(juan)材(cai)防(fang)水層(ceng)(ceng)施工(gong)(gong)的一般工(gong)(gong)藝流(liu)程：基(ji)層(ceng)(ceng)表(biao)面(mian)清(qing)理、修補→噴、涂基(ji)層(ceng)(ceng)處(chu)(chu)(chu)理劑→節點附加增強處(chu)(chu)(chu)理→定位(wei)、彈線(xian)、試鋪(pu)→鋪(pu)貼(tie)卷(juan)材(cai)→收頭處(chu)(chu)(chu)理、節點密(mi)封→清(qing)理檢查修整→保護層(ceng)(ceng)施工(gong)(gong)鋪(pu)貼(tie)方向：卷(juan)材(cai)應平行于(yu)屋(wu)脊鋪(pu)貼(tie)施工(gong)(gong)順(shun)序：防(fang)水層(ceng)(ceng)施工(gong)(gong)時(shi)，應先做(zuo)好節點、附加層(ceng)(ceng)和屋(wu)面(mian)排水比較集中(zhong)部位(wei)（如(ru)屋(wu)面(mian)與水落口(kou)連接處(chu)(chu)(chu)，檐(yan)(yan)口(kou)、天(tian)溝、檐(yan)(yan)溝、屋(wu)面(mian)轉角處(chu)(chu)(chu)、板(ban)端縫等）的處(chu)(chu)(chu)理，然后(hou)由屋(wu)面(mian)*低標高處(chu)(chu)(chu)向上施工(gong)(gong)。鋪(pu)貼(tie)天(tian)溝、檐(yan)(yan)口(kou)卷(juan)材(cai)時(shi)，宜順(shun)天(tian)溝、檐(yan)(yan)口(kou)方向，減少搭接。

8.節點處(chu)理：天(tian)溝(gou)(gou)(gou)(gou)、檐溝(gou)(gou)(gou)(gou)天(tian)溝(gou)(gou)(gou)(gou)、檐溝(gou)(gou)(gou)(gou)必(bi)須按設計要求找(zhao)(zhao)(zhao)坡，轉(zhuan)角(jiao)處(chu)應抹(mo)成規定(ding)(ding)的圓角(jiao)。找(zhao)(zhao)(zhao)坡（找(zhao)(zhao)(zhao)平(ping)層）宜用水(shui)泥砂漿抹(mo)面。厚度(du)超過(guo)20mm時，應采(cai)用細石混(hun)凝土，表面應抹(mo)平(ping)壓光。如(ru)天(tian)溝(gou)(gou)(gou)(gou)、檐溝(gou)(gou)(gou)(gou)過(guo)長，則應該按設計規定(ding)(ding)留(liu)好分格縫(feng)或設后澆帶，分格縫(feng)需(xu)(xu)填嵌密封(feng)材(cai)(cai)料。大面積(ji)防水(shui)層施工(gong)前，應按設計需(xu)(xu)要先鋪(pu)(pu)附(fu)加(jia)增強層，屋面與(yu)天(tian)溝(gou)(gou)(gou)(gou)交角(jiao)和天(tian)溝(gou)(gou)(gou)(gou)上部宜采(cai)取空鋪(pu)(pu)法，溝(gou)(gou)(gou)(gou)底(di)則采(cai)取滿粘法鋪(pu)(pu)貼。卷材(cai)(cai)附(fu)加(jia)增強層應順溝(gou)(gou)(gou)(gou)鋪(pu)(pu)貼，以減(jian)少卷材(cai)(cai)在(zai)溝(gou)(gou)(gou)(gou)內(nei)的搭接(jie)縫(feng)。
9.穿過防水層(ceng)的管(guan)道
管(guan)道穿(chuan)(chuan)(chuan)過(guo)防(fang)(fang)(fang)水(shui)層(ceng)分(fen)直(zhi)接(jie)穿(chuan)(chuan)(chuan)過(guo)和套(tao)管(guan)穿(chuan)(chuan)(chuan)過(guo)兩種(zhong)。直(zhi)接(jie)穿(chuan)(chuan)(chuan)過(guo)防(fang)(fang)(fang)水(shui)層(ceng)的(de)管(guan)道四(si)周(zhou)找平層(ceng)應(ying)按設計(ji)要求(qiu)放坡，與(yu)基(ji)層(ceng)交接(jie)處必須預留(liu)10mm×10mm的(de)槽，填(tian)嵌密(mi)封材(cai)料，再將管(guan)道四(si)周(zhou)除(chu)銹打(da)光，然后(hou)加鋪(pu)附加增強層(ceng)。用套(tao)管(guan)穿(chuan)(chuan)(chuan)過(guo)防(fang)(fang)(fang)水(shui)層(ceng)時，套(tao)管(guan)與(yu)基(ji)層(ceng)間(jian)的(de)做法與(yu)直(zhi)接(jie)穿(chuan)(chuan)(chuan)管(guan)做法相同，穿(chuan)(chuan)(chuan)管(guan)與(yu)套(tao)管(guan)之(zhi)間(jian)填(tian)彈性(xing)材(cai)料如泡(pao)沫(mo)塑(su)料，每端(duan)留(liu)深10mm以上凹槽嵌填(tian)密(mi)封的(de)防(fang)(fang)(fang)水(shui)材(cai)料，然后(hou)再做保護層(ceng)。
10.分(fen)格縫(feng)
分格縫(feng)的(de)設(she)置(zhi)(zhi)是為了使防水層有效地(di)適應各種變形的(de)影響，提高防水能力。但如果(guo)分格縫(feng)施工質量不好，則有可能成為漏源之一。分格縫(feng)應按設(she)計要求(qiu)填嵌密封材料(liao)。分格縫(feng)位(wei)置(zhi)(zhi)要準確(que)。一般應先(xian)彈(dan)線后嵌分格木條(tiao)(tiao)或(huo)聚苯乙(yi)烯(xi)（或(huo)聚乙(yi)烯(xi)）泡沫條(tiao)(tiao)，待砂(sha)漿或(huo)砼終凝后立(li)即取出(chu)木條(tiao)(tiao)。分格縫(feng)兩側應做(zuo)到順直、平整、密實(shi)，否則應及(ji)時(shi)修補(bu)，以保(bao)證(zheng)嵌縫(feng)材料(liao)粘(zhan)結牢固，交工前(qian)用油膏灌滿。
11.陰陽角防水(shui)層
陰陽角(jiao)的基層(ceng)(ceng)(ceng)應(ying)按設計要(yao)求作成半(ban)圓或倒角(jiao)。由于(yu)交接處應(ying)力集中，往往先(xian)于(yu)大(da)面積防水層(ceng)(ceng)(ceng)提前破損，因(yin)此在(zai)這些部(bu)位應(ying)加做附加增強層(ceng)(ceng)(ceng)，附加增強層(ceng)(ceng)(ceng)可采(cai)用(yong)涂料加筋涂刷(shua)或采(cai)用(yong)卷材(cai)條加鋪。陰角(jiao)處常以全粘(zhan)實鋪為(wei)主，陽角(jiao)處常采(cai)用(yong)空鋪為(wei)主。附加層(ceng)(ceng)(ceng)的寬度按設計規定，一般每邊(bian)粘(zhan)貼50mm為(wei)宜。也可采(cai)用(yong)密封材(cai)料涂刷(shua)2mm厚作為(wei)附加層(ceng)(ceng)(ceng)。
12.防(fang)水層收頭
防(fang)(fang)水(shui)層(ceng)的檐(yan)口部(bu)(bu)位的收頭，應距檐(yan)口邊緣50~100mm,并留(liu)凹槽以(yi)便防(fang)(fang)水(shui)層(ceng)端頭壓入凹槽，嵌填(tian)密封(feng)材(cai)料(liao)后不(bu)應產生(sheng)阻水(shui)。防(fang)(fang)水(shui)層(ceng)在泛水(shui)部(bu)(bu)位收頭距屋(wu)面(mian)找平層(ceng)*低高度應不(bu)小于(yu)250mm,待大面(mian)卷(juan)材(cai)鋪(pu)貼(tie)后，再對泛水(shui)和收頭做統一處理。鋪(pu)貼(tie)卷(juan)材(cai)前，收頭凹槽應抹聚合物水(shui)泥砂漿，使(shi)凹槽寬度和深度一致，并能(neng)順直、平整。
13.將(jiang)預留(liu)洞(dong)口濕潤(run)并(bing)清除洞(dong)口內(nei)殘(can)留(liu)雜物，充分澆水(shui)濕潤(run)，在補洞(dong)前(qian)洞(dong)壁四周先刷(shua)界(jie)面劑一道，厚2~3mm,再用1∶2防水(shui)砂(sha)漿填嵌(qian)入洞(dong)，補灰面應比墻面凹進10mm,此處周圍堵嵌(qian)油膏。
保護層(ceng)施(shi)工：每個部位經防(fang)(fang)水試驗24小時(shi)后，無滲(shen)漏(lou)、陰濕，應(ying)(ying)馬(ma)上進(jin)行保護層(ceng)施(shi)工。保護層(ceng)的(de)施(shi)工做法應(ying)(ying)符合設(she)計要求(qiu)，在(zai)上部施(shi)工鋼(gang)(gang)筋時(shi)應(ying)(ying)先(xian)鋪(pu)一層(ceng)保護砂漿在(zai)進(jin)行鋼(gang)(gang)筋鋪(pu)設(she)，以(yi)防(fang)(fang)防(fang)(fang)水層(ceng)破壞(huai)。
四 、成品保護
1、屋(wu)(wu)面工程完工后(hou)，應將屋(wu)(wu)面上所有剩(sheng)余材料，建筑垃圾等清理干凈(jing)，防止(zhi)堵塞水落口。
2、雨期處于惡劣(lie)環(huan)境(jing)中，受(shou)各種因素影響，易發生(sheng)滲漏(lou)，要安排(pai)具有專業防水(shui)知識的人員(yuan)進行管理。不能(neng)隨(sui)意在屋(wu)面(mian)上增加設施，堆重(zhong)物(wu)或雜物(wu)，更不能(neng)隨(sui)意鑿洞，以保持屋(wu)面(mian)防水(shui)層的正常施工狀態(tai)。
五、 屋面防水質量控制措(cuo)施
1、屋面(mian)結(jie)構(gou)砼(tong)澆(jiao)筑應連續進行，不得留置施(shi)工(gong)縫。振(zhen)搗(dao)時，除用(yong)(yong)插入式(shi)振(zhen)動(dong)棒振(zhen)搗(dao)外，表面(mian)還(huan)需用(yong)(yong)平板振(zhen)動(dong)器振(zhen)搗(dao)，砼(tong)初凝前，用(yong)(yong)鐵(tie)抹(mo)子收光。
2、對(dui)屋面(mian)防水進行(xing)48小時(shi)試水，并認真作好(hao)記錄，確認無滲(shen)漏(lou)(lou)現象才能進行(xing)下一(yi)道工序。如(ru)有滲(shen)漏(lou)(lou)，必須經過處理(li)并試水合格(ge)。
3、基層與突出屋面的結構(gou)連接的陰角(jiao)，均先作(zuo)泛水線，其圓弧半(ban)徑R≥
4、屋面雨水管(guan)穿女兒墻，先在管(guan)壁做防水一道，然后埋設雨水彎管(guan)，再灌管(guan)洞。
5、屋面(mian)防水(shui)(shui)工(gong)程應用專業施工(gong)隊伍組織實施，施工(gong)前必(bi)須編制屋面(mian)防水(shui)(shui)施工(gong)方(fang)案(an)。防水(shui)(shui)材(cai)料必(bi)須有材(cai)料合格(ge)證，防水(shui)(shui)操作工(gong)持證上崗，確保施工(gong)質量(liang)。
6、屋面作業的安全(quan)、文明施工及環境保護(hu)要求。
