從結(jié)構(gòu)上講，HDPE雙壁纏繞管的內(nèi)外壁比較光滑平整，管壁用中空型材經(jīng)螺旋纏繞制成的具有中空結(jié)構(gòu)的管材，剖面為“工”字鋼型結(jié)構(gòu)，從力學(xué)角度講，雙壁纏繞管材在受到外負(fù)荷時(shí)能更好保持結(jié)構(gòu)的穩(wěn)定性。而U-PVC加筋管及波紋管為加強(qiáng)筋結(jié)構(gòu)，以加強(qiáng)筋來(lái)抵抗外壓。另外，HDPE纏繞管咨詢(xún)問(wèn)價(jià)，HDPE纏繞管咨詢(xún)問(wèn)價(jià)，結(jié)構(gòu)的不同對(duì)管土共同作用的體現(xiàn)也不同，HDPE纏繞管咨詢(xún)問(wèn)價(jià)。影響管土共同作用的主要因素有，管材外壁的平整程度和回填材料的變形模量值及密實(shí)度等因素。因此HDPE雙壁纏繞管平整的外壁更有利于提高回填材料的密實(shí)度，更好的體現(xiàn)管土共同作用理論。

</p> <p> （1）從材質(zhì)上來(lái)比較，混凝土材質(zhì)的耐腐蝕、耐磨等性能遠(yuǎn)低于HDPE材質(zhì)。 </p> <p> （2）混凝土管在華東地區(qū)的使用壽命為10-15年，而HDPE雙壁纏繞管在50年以上。 </p> <p> （3）纏繞管的水阻系數(shù)為0.0078-0.0092，一般設(shè)計(jì)取0.01，混凝土管的水阻系數(shù)為0.013-0.014，比纏繞管高30%-40%。也就是說(shuō)流量和流速低30%-40%。實(shí)際證明，同等流量時(shí)，纏繞管可以換用低一個(gè)的管材口徑，如可用DN500mm的纏繞管代替DN600mm的混凝土管。 </p> <p> （4）纏繞管是環(huán)保產(chǎn)品，可***回收，混凝土管則不能。 </p> <p> （5）纏繞管施工方便，砂石基礎(chǔ)，即時(shí)開(kāi)挖即時(shí)回填，重量公為同等水泥管的1/8，無(wú)需大型吊車(chē)等工具，施工周期短，日常維護(hù)費(fèi)用低，綜合造價(jià)與水泥管相當(dāng)。 </p> <p> <br />

，大口徑纏繞管,雙壁纏繞管,中空纏繞管是一種以高密度聚乙烯(HDPE)為原料，經(jīng)纏繞焊接成型的一種管材，由于其獨(dú)特的成型工藝，可以生產(chǎn)直徑達(dá)3米的管材，這是其他生產(chǎn)工藝難以完成的。高密度聚乙烯(HDPE)由于其本身優(yōu)異的融焊接性能不但保證了產(chǎn)品成型工藝和產(chǎn)品質(zhì)量，而且也為施工連接提供了多種可靠方式，如電熱熔焊接，熱收縮連接等等，同時(shí)這也是滲漏情況很少出現(xiàn)的一個(gè)重要原因，也正是因?yàn)檫@個(gè)原因，這種管材才具有其它管材不具備的獨(dú)特的環(huán)保功能，這對(duì)當(dāng)前人們關(guān)注的污染防治提供了非常有效的方法。由于中空壁纏繞管屬化學(xué)建材，對(duì)節(jié)省能源、減小污染、保護(hù)環(huán)境具有重要意義。
