<p> ①連接前，應(yīng)先檢查橡膠圈是否配套完好，確認(rèn)橡膠圈安放位置及插口應(yīng)插入承口的深度。 </p> <p> ②接口作業(yè)時，應(yīng)先將承口的內(nèi)工作面用棉紗清理干凈,不得有泥土等雜物并在承口內(nèi)工作面涂上潤滑劑，然后立即將插口端的中心對準(zhǔn)承口的中心軸線就位。 </p> <p> ③插口插入承口時，小口徑管可用人力，在管端部位設(shè)置木擋板,用撬棍將被安裝的管材沿著對準(zhǔn)的軸線徐徐插入承口內(nèi)，逐節(jié)依次安裝;管徑大于400mm的管道,可用纜繩系住管材用手搬葫蘆等體力工具安裝:嚴(yán)禁采用施工機(jī)械強(qiáng)行推頂管子插入承口。 </p> <p> (2)橡膠圈的位置應(yīng)放在插口第二至第三個波紋間的槽內(nèi)，注意橡膠圈的方向。 </p> <p> (3)冬、雨季施工應(yīng)采取防凍措施和防止管材漂浮的措施,不得使用凍硬的橡膠圈。 </p> <p> 2.2.4溝槽回填 </p> <p> （1）PVC-U雙壁波紋管溝槽回填的密實度要求 </p> <p> (2) HDPE雙壁波紋管溝槽回填必須平格要求控制施工質(zhì)量,應(yīng)符合現(xiàn)行的《市政排水管渠工程質(zhì)量檢驗評定標(biāo)準(zhǔn)》CJJ3- 90。先從管底與基礎(chǔ)結(jié)合部開始,沿管身兩側(cè)同時對稱分居回填并夯實，每層回填高度不超過20cm,直至管頂以上30cm?；靥畈牧腺|(zhì)量應(yīng)符合設(shè)計要求。 </p>塑料埋地排水管屬于“柔性管”，即在破壞之前可以有較大的變形。而混凝土排水管屬于“剛性管”，即在破壞之前不可能有較大變形。當(dāng)埋在地下承受外壓負(fù)載時，“柔性管”和“剛性管”的機(jī)理是完全不同的。 <p> 3、水力特性比較：塑料管的內(nèi)壁粗糙度為n=0.01，而混凝土管為n=0.013，根據(jù)流速公式V=1/n** ，在相同管徑與水力坡降條件下，雙壁波紋管與水泥管的輸水量相差30%以上。 </p> <p> 4、運(yùn)輸安裝與施工比較：雙壁波紋管重量輕，運(yùn)輸和搬運(yùn)方便，施工速度快，安裝費(fèi)用低，根據(jù)測算：如DN500mm管材用3-4人既可安裝，時間只需5-6min，正常情況下，從開挖(用機(jī)械開挖)――平基――裝管――回填，8小時可裝管40m，比同口徑的水泥管安裝時間節(jié)省50%以上。而水泥管需機(jī)械吊裝，所以在安裝費(fèi)中還要扣除機(jī)械臺班費(fèi)。波紋管批發(fā)、HDPE雙壁波紋管、PE雙壁波紋管，昆明元森商貿(mào)。</p><div

src="http://tyunfile.71360.com/UploadFile/yuansenshangmao/637179004146933593/7145969.jpg"></div><p> HDPE雙壁波紋管常見缺點(diǎn)的原因 </p> <p> <br /> </p> <p> 1、內(nèi)壁不平坦 </p> <p> PE雙壁波紋管內(nèi)壁不平坦通常由真空度偏小、水套溫度過高、內(nèi)層過薄等導(dǎo)致。真空度偏小應(yīng)當(dāng)查看內(nèi)層真空管路是不是疏通，真空泵是不是作業(yè)正常等。水套溫度過高通常是由于冷卻水的水溫過高或冷卻水的流量過小導(dǎo)致，可通過這兩個方面的調(diào)整來處理。 </p> <p> 2、擴(kuò)口不良。擴(kuò)口不良可分為以下幾種狀況： </p> <p> a、內(nèi)層被吹破緣由通常有內(nèi)層沖氣氣壓過大；原材料耐性欠好；內(nèi)層過薄；擴(kuò)口放氣發(fā)動晚或擴(kuò)口放氣管路不曉暢；原材料內(nèi)有雜質(zhì)；物料塑化不良等。 </p> <p> b、擴(kuò)口內(nèi)外層未貼好若是這種表象發(fā)生在始端，則由于內(nèi)層沖氣發(fā)動較晚或相應(yīng)段的氣壓過??； </p> <p> c、擴(kuò)口不完整擴(kuò)口的結(jié)尾不管怎樣調(diào)整都無法貼上，緣由通常是內(nèi)層沖氣提前結(jié)束了，擴(kuò)口放氣提前結(jié)束了 </p> <p> d、擴(kuò)口前端的內(nèi)層有凹限引起這種現(xiàn)象的原因一般是內(nèi)層沖氣過早啟動；水套與在型模塊的中線偏離（成型機(jī)與水套不對中）；內(nèi)層壁厚偏??；內(nèi)層真空過早停止。 </p> <p> e、擴(kuò)口末端內(nèi)層堆料，這種現(xiàn)象往往會導(dǎo)致擴(kuò)口往里面凹。其原因是擴(kuò)口末端內(nèi)層料過厚；成型機(jī)在此段的降速的量過大； </p> <p> f、擴(kuò)口末端的內(nèi)層有凹限其原因一般是擴(kuò)口后的1個波和2個波內(nèi)的氣壓過?。?</p> <p> <br />

隨著我國工業(yè)的發(fā)展，越來越多的新型材料運(yùn)用到了建筑行業(yè)，從而替代了老一套的建筑材料，作為新型材料的典型——雙壁波紋管不可置疑的用到了建筑排水排污系統(tǒng)，使工程的施工進(jìn)度、施工技術(shù)等各方面都起到了一定的推動作用。 </p> <p> 一.性能特點(diǎn): </p> <p> 1.1環(huán)剛強(qiáng)度高、撓曲性能好，可抗不均勻沉降 </p> <p> 雙壁波紋管分PVC-U雙壁波絞管和HDPE雙壁波絞管，雙壁波紋管的環(huán)剛度分為2個級別: S1、S2, 可根據(jù)用戶的要求和不同的使用場合來選擇不同的等級。雙壁波紋管環(huán)形結(jié)構(gòu)剛?cè)峒鎮(zhèn)?，抗壓、抗沖擊，有適當(dāng)?shù)膿锨?可不用管件直接將管材鋪設(shè)于略彎的溝槽內(nèi)，可順應(yīng)地基的不均勻沉降，不會產(chǎn)生象砼管的脫節(jié)、斷裂等現(xiàn)象。 </p> <p> 1.2材質(zhì)輕，施工工序簡單、進(jìn)度快 </p> <p> 雙壁波紋管質(zhì)量輕(密度≤1.5g/cm3),*為砼管的1/5, 搬運(yùn)、吊裝輕便，施工人員勞動強(qiáng)度小。其施工流程比砼管大為簡化(見圖1、2), 另外，雙壁波紋管定長為6m (砼管定長為1~2m)接口數(shù)量少，接管快捷，很大程度上地縮短了工期。云南PE雙壁波紋管價格</p><p
