class="box"><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。當埋在地下承受外壓負載時，“柔性管”和“剛性管”的機理是完全不同的。 <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、運輸安裝與施工比較：雙壁波紋管重量輕，云南昆明專業(yè)雙壁波紋管經(jīng)銷商，運輸和搬運方便，施工速度快，安裝費用低，根據(jù)測算：如DN500mm管材用3-4人既可安裝，云南昆明專業(yè)雙壁波紋管經(jīng)銷商，時間只需5-6min，正常情況下，從開挖(用機械開挖)――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。而水泥管需機械吊裝，云南昆明專業(yè)雙壁波紋管經(jīng)銷商，所以在安裝費中還要扣除機械臺班費。由于HDPE雙壁波紋管和HDPE中空壁纏繞管的生產(chǎn)工藝不同，原料利用率也不同。云南昆明專業(yè)雙壁波紋管經(jīng)銷商</p><div

（1）橡膠圈安裝位置應在插口第二與第三波紋之間槽內(nèi)，安裝密封圈的數(shù)量視設計要求而定，當采用兩只密封圈時建議兩密封圈之間隔一個波紋； </p> <p> （2）接口前應先將承口插口內(nèi)外表面清理干凈，在插口套入密封圈，并在承口內(nèi)工作面和橡膠圈表面涂上潤滑劑（一般用肥皂水即可），插入方向為水流方向，對準承口中心線用人力或設置木擋板用撬棍將被安裝的管材徐徐插入承口內(nèi)直至底部； </p> <p> （3）接口完成后，隨即用相同土質(zhì)把預留凹槽處填筑密實； </p> <p> （4）管道應直線敷設，相鄰兩節(jié)管道軸線的允許轉(zhuǎn)角一般不得大于2度。 </p> <p> 五、用途范圍 </p> <p> 除兩種管材共用的領(lǐng)域如市政工程、小區(qū)地下排水排污工程、高速公路工程、農(nóng)田水利灌溉工程外，PE雙壁波紋管還可應用于化工礦山流體輸送工程，范圍相對更廣。 </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)層過薄等導致。真空度偏小應當查看內(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致，可通過這兩個方面的調(diào)整來處理。 </p> <p> 2、擴口不良。擴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??；擴口放氣發(fā)動晚或擴口放氣管路不曉暢；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)動較晚或相應段的氣壓過?。?</p> <p> c、擴口不完整擴口的結(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，擴口放氣提前結(jié)束了 </p> <p> d、擴口前端的內(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、擴口末端內(nèi)層堆料，這種現(xiàn)象往往會導致擴口往里面凹。其原因是擴口末端內(nèi)層料過厚；成型機在此段的降速的量過大； </p> <p> f、擴口末端的內(nèi)層有凹限其原因一般是擴口后的1個波和2個波內(nèi)的氣壓過?。?</p> <p> <br /> </p><h2> 公司簡介 </h2> <p>

隨著我國工業(yè)的發(fā)展，越來越多的新型材料運用到了建筑行業(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: </p> <p> 1.1環(huán)剛強度高、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)洌箟?、抗沖擊，有適當?shù)膿锨?可不用管件直接將管材鋪設于略彎的溝槽內(nèi)，可順應地基的不均勻沉降，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、吊裝輕便，施工人員勞動強度小。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。 PVC雙壁波紋管生產(chǎn)原料為聚氯乙烯，PE雙壁波紋管生產(chǎn)原料為聚乙烯。云南昆明專業(yè)雙壁波紋管經(jīng)銷商</p><p style="text-indent:25px">波紋管、HDPE雙壁波紋管、云南PE雙壁波紋管，昆明元森商貿(mào)。云南昆明專業(yè)雙壁波紋管經(jīng)銷商</p><p style="text-indent:25px">波紋管的在各個行業(yè)的很多運用，在實際加工和使用中，經(jīng)常會出現(xiàn)一些原因使得波紋管損壞，這是需要我們注意的地方，下面接著帶大家了解波紋管的保護要點。 1. 搬運到現(xiàn)場的波紋管要集中堆放整齊，不能在波紋管上踩。2. 波紋管要覆蓋保護，防止風吹雨淋使其提前老化。3. 切割波紋管要平直，不能切成斜口。4. 波紋管接頭的方法：波紋管接頭處要外包0.3米長的大號波紋管，并且兩端頭要對半擰緊，中間不得留有空隙。為保證中間不留空隙，應在兩接頭端頭處做好標記。做好后要用膠帶包裹嚴密，以防漏漿。5. 波紋管位置定位要準確，尤其是靠近接頭的部位，波紋管定位鋼筋間距為0.5米，不能缺少。6. 焊接鋼筋靠近波紋管時，要采取措施保護波紋管不能被灼傷，如果不小心被灼傷到，灼傷處要用膠帶包裹嚴密。7. 考慮到頂板波紋管數(shù)量在逐漸減少，但凡與波紋管不匹配的部件都要避讓波紋管。8. 澆筑砼時，不能對著波紋管放料。振搗棒不能與波紋管碰撞，嚴禁兩個振搗棒夾著一根波紋管振搗。特別是腹板振搗時，嚴禁振搗棒在同一位置長時間振搗，振搗時間以不超過20秒為準。9. 拆模時注意保護端頭處外漏的波紋管。云南昆明專業(yè)雙壁波紋管經(jīng)銷商</p><p
