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，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，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，云南聚乙烯雙壁波紋管廠家現(xiàn)貨，比同口徑的水泥管安裝時間節(jié)省50%以上，云南聚乙烯雙壁波紋管廠家現(xiàn)貨，云南聚乙烯雙壁波紋管廠家現(xiàn)貨。而水泥管需機械吊裝，所以在安裝費中還要扣除機械臺班費。采用雙壁波紋管比相同口徑的其他管材可通過更大的流量。云南聚乙烯雙壁波紋管廠家現(xiàn)貨</p><div

</p> <p> 雙壁波紋管的施工 </p> <p> 2.1溝槽的開挖 </p> <p> 2.1.1管槽開挖以直線為宜，槽底開挖寬度為DN+0.30m.遇到管道在地下連接時，應適當增加接口處槽底寬度，管道槽底寬度不宜小于DN+0.50m,以方便安裝對接為宜。 </p> <p> 2.1.2管道埋設時**小管頂覆土深度應符合下列要求： </p> <p> （1）埋設在車行道下時，不應小于0.80m。 </p> <p> （2）埋設在人行道下時，不應小于0.60m。 </p> <p> 2.1.3當橫穿車行道達不到設計深度時，應采取敷設鋼制套管的措施進行保護。 </p> <p> 2.1.4管槽必須轉(zhuǎn)彎時，轉(zhuǎn)彎角度不宜過大 </p> <p> <br /> 云南聚乙烯雙壁波紋管廠家現(xiàn)貨由于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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南聚乙烯雙壁波紋管廠家現(xiàn)貨,雙壁波紋管"

6、施工方便 </p> <p> 由于雙壁波紋管重量輕，搬運和連接都很方便，所以施工快捷、維護工作簡單。在工期緊和施工條件差的情況下，其優(yōu)勢更加突出。 </p> <p> 雙壁波紋管由德國引進，現(xiàn)在已經(jīng)被開發(fā)出來越來越多的型號，形成了一個系列品牌，相信在不久以后，這種管材的性能還會有更大的提高，面對更加嚴峻的社會建設任務時，雙壁波紋管將是會越來越受到大家的喜愛。 </p><p> 2、抗壓性較強 </p> <p> 外壁呈環(huán)形波紋狀結構，很大程度上增強了管材的環(huán)剛度，從而增強了管道對土壤壓力的抵抗力，在這個性能上，雙壁波紋管與其他管材相比較具有明顯的優(yōu)勢。 </p> <p> 3、內(nèi)壁摩擦小，流量大 </p> <p> 采用雙壁波紋管比相同口徑的其他管材可通過更大的流量。換言之，相同的流量要求下，可采用口徑相對較小的雙壁波紋管。 </p> <p> 4、化學穩(wěn)定性 </p> <p> 由于管材分子沒有極性，所以化學穩(wěn)定性極好。除少數(shù)的強氧化劑外，大多數(shù)化學介質(zhì)對其不起破壞作用。一般使用環(huán)境的土壤、電力、酸堿因素都不會使該管道破壞，不滋生細菌，不結垢，其流通面積不會隨運行時間增加而減少。在選擇PE雙壁波紋管管道的環(huán)剛度之前，我們應該對管道的所有方面進行理解。</p><div
