塑料排水管屬于“柔性管”，即在破壞之前可以有較大的變形，成都日豐碳素波紋管批發(fā)。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。使用壽命和耐腐蝕方面對比：普通的鋼筋混凝土管的使用壽命一般為20-25年，而波紋管則長達(dá)50年以上，成都日豐碳素波紋管批發(fā)，對埋設(shè)在腐蝕性土壤或輸送腐蝕性的廢水，二者的相關(guān)更為懸殊，塑料管的表現(xiàn)遠(yuǎn)好于水泥管;在維修管理上，塑料管由于管壁光滑，成都日豐碳素波紋管批發(fā)，積污少，而且耐腐蝕、耐磨性和耐久性好，養(yǎng)護(hù)管理的費(fèi)用也相應(yīng)降低。

碳素波紋管施工中的問題？碳素波紋管在裝飾裝修吊頂工程中，如果前工序現(xiàn)澆板澆筑前未對碳素波紋管進(jìn)行標(biāo)記，造成各專業(yè)打吊筋時將預(yù)埋線管打穿，導(dǎo)致穿線時不能導(dǎo)通，這樣就必須在吊頂內(nèi)重新敷設(shè)線管。現(xiàn)場技術(shù)交底不細(xì)致，工人施工態(tài)度不認(rèn)真。施工工人為了方便省工，將兩根或多根碳素波紋管并排緊貼敷設(shè)，截管長度不夠精確，穿進(jìn)接線盒內(nèi)長度長短不一，管口不齊，承插口太短，未涂粘結(jié)劑，未使用鎖母鎖緊。特別是在大型公共辦公建筑中，涉及專業(yè)較多，包括照明用電、空調(diào)用電、綜合布線、火災(zāi)自動報警等，現(xiàn)澆板內(nèi)需敷設(shè)導(dǎo)管較多，專業(yè)間管路出現(xiàn)兩根或三根交又敷設(shè)現(xiàn)象，如不進(jìn)行處理則影響鋼筋保護(hù)層厚度，出現(xiàn)露筋現(xiàn)象，從而影響現(xiàn)澆板澆筑質(zhì)量。

HDPE雙壁波紋管施工很方便，因為它重量比較輕，方便運(yùn)輸和連接。相比較相同口徑的管材來說，HDPE管材的流量更大，因此，在對流量有要求的情況下，選擇口徑較小的HDPE管材就能達(dá)到要求。市政排水中，對于管材的選擇有著諸多要求，因為市政排水的水質(zhì)較差，居民生活用水、自然界的水源等大多含有腐蝕性物質(zhì)、雜質(zhì)等，因此需要排水管材具有良好的防腐蝕性能，HDPE雙壁波紋管恰好符合這一要求。同時，市政排水要求管材輸水能力較強(qiáng)，水流速度快，且管材不能輕易移動，HDPE波紋管也能滿足這樣的要求。因此，市政排水管材推薦HDPE波紋管。
