所有(you)(you)的(de)(de)機械設備都有(you)(you)自己的(de)(de)標(biao)(biao)準(zhun)，只有(you)(you)達到哪(na)個標(biao)(biao)準(zhun)時(shi)(shi)才能(neng)發(fa)揮它大的(de)(de)作用，制作的(de)(de)每個步驟都有(you)(you)嚴(yan)格的(de)(de)要求，都會有(you)(you)該有(you)(you)的(de)(de)檢驗(yan)方(fang)式，對產品的(de)(de)選材非常嚴(yan)格，要求必須達到國標(biao)(biao)圖集的(de)(de)厚度。翼環和套(tao)管(guan)厚度應(ying)(ying)符合規范要求，防(fang)水(shui)套(tao)管(guan)的(de)(de)翼環兩邊應(ying)(ying)雙面(mian)滿焊(han)，且焊(han)縫(feng)飽(bao)滿，平整，光滑，無(wu)夾渣，無(wu)氣泡，無(wu)裂紋等現象。那么柔性防(fang)水(shui)套(tao)管(guan)在檢驗(yan)安(an)裝(zhuang)時(shi)(shi)怎么滿足(zu)要求呢.下(xia)面(mian)就讓我們了解一下(xia)。
柔(rou)(rou)性(xing)(xing)(xing)(xing)防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)安(an)裝前(qian)，應(ying)(ying)(ying)作強度性(xing)(xing)(xing)(xing)和(he)(he)嚴密(mi)性(xing)(xing)(xing)(xing)試(shi)(shi)驗(yan)。試(shi)(shi)驗(yan)應(ying)(ying)(ying)在每批(同型號、同規格(ge)、同牌(pai)號)數(shu)量中(zhong)(zhong)抽(chou)查10%，且不(bu)(bu)少(shao)于一個(ge)。對于安(an)裝在主干(gan)管(guan)上(shang)起(qi)切(qie)斷(duan)作用(yong)(yong)(yong)的(de)(de)防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)，應(ying)(ying)(ying)逐個(ge)做強度和(he)(he)嚴密(mi)性(xing)(xing)(xing)(xing)試(shi)(shi)驗(yan)。防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)的(de)(de)強度性(xing)(xing)(xing)(xing)和(he)(he)嚴密(mi)性(xing)(xing)(xing)(xing)試(shi)(shi)驗(yan)應(ying)(ying)(ying)符合(he)(he)以下(xia)規定:柔(rou)(rou)性(xing)(xing)(xing)(xing)防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)的(de)(de)強度試(shi)(shi)驗(yan)壓力為(wei)公稱壓力的(de)(de)1.5倍，嚴密(mi)性(xing)(xing)(xing)(xing)試(shi)(shi)驗(yan)壓力為(wei)公稱壓力的(de)(de)1,1倍;試(shi)(shi)驗(yan)壓力在試(shi)(shi)驗(yan)持續(xu)(xu)時(shi)(shi)(shi)間內(nei)應(ying)(ying)(ying)保持不(bu)(bu)變，且殼體填(tian)料(liao)及閥瓣(ban)密(mi)封面(mian)無滲漏。柔(rou)(rou)性(xing)(xing)(xing)(xing)防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)試(shi)(shi)壓的(de)(de)持續(xu)(xu)時(shi)(shi)(shi)間應(ying)(ying)(ying)不(bu)(bu)少(shao).柔(rou)(rou)性(xing)(xing)(xing)(xing)防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)施(shi)工中(zhong)(zhong)應(ying)(ying)(ying)注意防(fang)止雜物(wu)落下(xia)砸傷防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan);防(fang)止地(di)(di)面(mian)雨水(shui)(shui)(shui)(shui)(shui)(shui)流人(ren)溝內(nei);施(shi)工中(zhong)(zhong)斷(duan)時(shi)(shi)(shi)應(ying)(ying)(ying)臨時(shi)(shi)(shi)封堵(du)管(guan)口(kou)(kou)(kou)。對濕陷性(xing)(xing)(xing)(xing)黃土、季節性(xing)(xing)(xing)(xing)凍土和(he)(he)膨脹土地(di)(di)區，埋(mai)地(di)(di)管(guan)敷設應(ying)(ying)(ying)符合(he)(he)有(you)關規范規定。甲防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)與鑄鐵管(guan)連接(jie)時(shi)(shi)(shi)，宜(yi)采用(yong)(yong)(yong)專用(yong)(yong)(yong)配件。當(dang)采用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)泥捻(nian)口(kou)(kou)(kou)連接(jie)時(shi)(shi)(shi)，應(ying)(ying)(ying)先將防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)插(cha)人(ren)承口(kou)(kou)(kou)部(bu)分(fen)的(de)(de)外(wai)側，用(yong)(yong)(yong)砂(sha)紙(zhi)打(da)毛或涂(tu)刷膠(jiao)勃劑后(hou)滾粘干(gan)燥的(de)(de)黃砂(sha);插(cha)人(ren)后(hou)應(ying)(ying)(ying)用(yong)(yong)(yong)油麻絲填(tian)嵌均勻，用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)泥捻(nian)口(kou)(kou)(kou)。柔(rou)(rou)性(xing)(xing)(xing)(xing)防(fang)水(shui)(shui)(shui)(shui)(shui)(shui)套(tao)(tao)(tao)管(guan)道安(an)裝完畢，覆土之前(qian)必須(xu)做灌(guan)水(shui)(shui)(shui)(shui)(shui)(shui)試(shi)(shi)驗(yan)。灌(guan)水(shui)(shui)(shui)(shui)(shui)(shui)試(shi)(shi)驗(yan)合(he)(he)格(ge)后(hou)方(fang)可進行回(hui)(hui)填(tian)土，回(hui)(hui)填(tian)土應(ying)(ying)(ying)為(wei)素土，且分(fen)層(ceng)回(hui)(hui)填(tian)，每層(ceng)的(de)(de)厚度宜(yi)為(wei)0.15m.
看到這么多的要(yao)(yao)求(qiu)是不(bu)是有點頭暈呢(ni)，其實只要(yao)(yao)他的要(yao)(yao)求(qiu)達(da)到規定的要(yao)(yao)求(qiu)就不(bu)會有事，柔(rou)性防水套管所(suo)用材料、成品、半成品、配件、器(qi)具和設備必須具有中文質量合(he)格證明文件，規格、型(xing)號及性能檢測報告應符合(he)國家(jia)技術(shu)標準或設計(ji)要(yao)(yao)求(qiu)。進場時(shi)應做檢查驗(yan)收，并經工(gong)程師(shi)核(he)查確認。所(suo)以我們在(zai)購買(mai)的時(shi)候(hou)不(bu)能因(yin)為某些殘(can)次(ci)防水套管價格便宜(yi)就冒(mao)然購買(mai)。
