鋼帶波紋管HDPE雙(shuang)壁波紋管的主要優點:
    (1):有足夠(gou)的強度和剛度
HDPE雙(shuang)(shuang)(shuang)壁波紋(wen)管(guan)(guan)(guan)埋(mai)地排(pai)水(shui)、排(pai)污管(guan)(guan)(guan),屬于(yu)柔(rou)性(xing)(xing)(xing)管(guan)(guan)(guan),其特性(xing)(xing)(xing)是(shi)剛(gang)(gang)(gang)(gang)柔(rou)兼備(bei),即具(ju)有足夠(gou)的(de)力(li)(li)學(xue)性(xing)(xing)(xing)能(neng)(neng)和剛(gang)(gang)(gang)(gang)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng),同(tong)(tong)(tong)(tong)時兼備(bei)優(you)異的(de)柔(rou)韌性(xing)(xing)(xing)。柔(rou)性(xing)(xing)(xing)管(guan)(guan)(guan)與剛(gang)(gang)(gang)(gang)性(xing)(xing)(xing)管(guan)(guan)(guan)的(de)承受負(fu)載(zai)(zai)的(de)機理(li)是(shi)完全不同(tong)(tong)(tong)(tong)的(de),柔(rou)性(xing)(xing)(xing)管(guan)(guan)(guan)在(zai)破(po)壞(huai)之(zhi)前可(ke)(ke)以(yi)有較大(da)(da)的(de)變形(xing),而剛(gang)(gang)(gang)(gang)性(xing)(xing)(xing)管(guan)(guan)(guan)不可(ke)(ke)能(neng)(neng)。同(tong)(tong)(tong)(tong)樣(yang)外(wai)壓(ya)負(fu)載(zai)(zai)下,柔(rou)性(xing)(xing)(xing)管(guan)(guan)(guan)管(guan)(guan)(guan)壁內的(de)應力(li)(li)較小,它和周圍(wei)的(de)回填土(tu)共同(tong)(tong)(tong)(tong)承受負(fu)載(zai)(zai),管(guan)(guan)(guan)土(tu)共同(tong)(tong)(tong)(tong)作(zuo)用。因此,雙(shuang)(shuang)(shuang)壁波紋(wen)管(guan)(guan)(guan)不需要和剛(gang)(gang)(gang)(gang)性(xing)(xing)(xing)混凝土(tu)一(yi)樣(yang)的(de)強(qiang)度和剛(gang)(gang)(gang)(gang)度,在(zai)合理(li)的(de)剛(gang)(gang)(gang)(gang)度下,完全可(ke)(ke)以(yi)達到(dao)使用要求(qiu),這一(yi)點已被一(yi)些發達國家的(de)應用實踐所證實。與水(shui)泥(ni)管(guan)(guan)(guan)相比,雙(shuang)(shuang)(shuang)壁波紋(wen)管(guan)(guan)(guan)不僅質量(liang)輕,還有很大(da)(da)的(de)壓(ya)縮強(qiang)度和良(liang)好的(de)耐沖擊性(xing)(xing)(xing)能(neng)(neng)、抗彎曲性(xing)(xing)(xing)能(neng)(neng),能(neng)(neng)承受土(tu)體與動力(li)(li)負(fu)荷載(zai)(zai)體的(de)雙(shuang)(shuang)(shuang)重(zhong)壓(ya)力(li)(li),可(ke)(ke)適(shi)應土(tu)壤的(de)不均勻沉降。
(2):具有良好的水(shui)利特性
HDPE雙(shuang)壁(bi)波紋(wen)管內壁(bi)光滑、流阻小,其粗糙系數僅為0.009,而混(hun)凝土管為0.013,
它(ta)可(ke)(ke)以(yi)使水更(geng)流暢(chang),提高(gao)輸水能力(li)。在(zai)相同(tong)使用(yong)條件(jian)下(xia),雙壁(bi)波(bo)紋(wen)管的輸水量比混凝土管提高(gao)30%。實(shi)踐(jian)證明(ming),在(zai)同(tong)等的坡度下(xia),采用(yong)直(zhi)徑較小的PE雙壁(bi)波(bo)紋(wen)管就可(ke)(ke)以(yi)達到要求的流量,并(bing)且還可(ke)(ke)以(yi)避(bi)免(mian)廢棄物的囤積停滯,免(mian)除管路日后疏通之憂。
(3):不泄露(lu)、防止污染環境(jing)
HDPE雙(shuang)壁波紋管(guan)的水密性*,因采用橡膠密封圈承插方(fang)式連(lian)接(jie),可確保(bao)管(guan)內(nei)污水不(bu)泄露,并(bing)可順應地基的不(bu)均勻(yun)沉(chen)降,不(bu)會(hui)產生如剛(gang)性混凝土管(guan)的脫節(jie)斷(duan)裂現象,防止污水污染(ran)。
(4):使用(yong)壽命(ming)長、耐(nai)腐蝕、耐(nai)磨損
雙(shuang)壁波(bo)紋管耐(nai)化學(xue)腐蝕性(xing)強(qiang),可承(cheng)受土壤中酸堿的(de)影響。塑料埋地排水管的(de)耐(nai)磨(mo)性(xing)也(ye)非常(chang)好。埋地使用壽命可達50年(nian)以(yi)上(shang)。
(5):便于(yu)鋪設、安裝
HDPE雙壁波(bo)紋管(guan)比混凝土管(guan)輕、長度大(da)(da)(da)、接(jie)頭少、對(dui)于(yu)管(guan)溝和地(di)基的要求低(di),接(jie)口連(lian)接(jie)方便(bian)且密封性好。易搬(ban)運、施工簡單方便(bian)、無需吊裝設備,人工即可(ke)安(an)裝。施工勞(lao)動強度低(di)、速(su)度快,可(ke)大(da)(da)(da)大(da)(da)(da)提高施工效(xiao)率、縮短(duan)工期。在擁擠(ji)或地(di)質惡劣(lie)地(di)區(如地(di)下水位高,地(di)基松軟),土工雙壁波(bo)紋管(guan)具有更(geng)大(da)(da)(da)的優勢。
