PVC雙壁波紋管與PE雙壁波紋管施工方法相同。 </p> <p> （1）橡膠圈安裝位置應(yīng)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(shè)計(jì)要求而定，當(dāng)采用兩只密封圈時(shí)建議兩密封圈之間隔一個(gè)波紋； </p> <p> （2）接口前應(yīng)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(rùn)滑劑（一般用肥皂水即可），插入方向?yàn)樗鞣较颍瑢?duì)準(zhǔn)承口中心線用人力或設(shè)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>

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(yīng)用于化工礦山流體輸送工程，范圍相對(duì)更廣。 </p> 云南正規(guī)雙壁波紋管規(guī)格齊全波紋管、HDPE雙壁波紋管批發(fā)、PE雙壁波紋管，昆明元森商貿(mào)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南昆明專業(yè)雙壁波紋管批發(fā),雙壁波紋管" src="http://tyunfile.71360.com/UploadFile/yuansenshangmao/637179004145654296/9281509.jpg"></div><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(dāng)埋在地下承受外壓負(fù)載時(shí)，“柔性管”和“剛性管”的機(jī)理是完全不同的。 </p> <p> 2、密封性和維修方面比較：在管道嚴(yán)密性方面，塑料管本身不會(huì)滲漏，而且管子的長(zhǎng)度長(zhǎng)、接頭少;另外橡膠圈承插連接，柔性接口，密封性好，抗不均勻沉降能力強(qiáng)，能適應(yīng)較大的角度變化，因此其滲漏量遠(yuǎn)低于混凝土管道，甚至可以做到零滲漏。而混凝土管道的滲漏在管道工程設(shè)計(jì)時(shí)，通常按照排水量的10%來(lái)考慮;如果地下水位低于管底時(shí)，會(huì)導(dǎo)致管內(nèi)水向外滲漏污染地下水，造成二次污染;如果地下水位高于管底時(shí)，會(huì)導(dǎo)致地下水向內(nèi)滲漏，加大管道的排水量，在污水管道接入污水處理廠時(shí)，將使污水處理廠的處理水量增加，加大了污水處理的費(fèi)用。此外，還有在流沙地區(qū)水泥管的沉管問(wèn)題，容易造成水土流失、管道下沉堵塞等非正常損傷事件，*在上海地區(qū)每年沉管修理費(fèi)就高達(dá)1000萬(wàn)元以上。 </p><p> 第四，并不總是有可能確保鋪設(shè)條件良好。如果鋪設(shè)條件較好，圓環(huán)剛度低的管道不會(huì)有較大的變形，反之，如果鋪設(shè)條件不好，即環(huán)剛度較高的管道也可能變形過(guò)大，出現(xiàn)壓力不穩(wěn)定。 </p> <p> 第五，一般情況下，直徑小于500mm的塑料埋地排水管：一般選用環(huán)剛度≥8kN/㎡的排水管，*選用環(huán)剛度為4kn/㎡的排水管，地質(zhì)條件好，不運(yùn)輸車輛荷載。 </p> <p> 第六，直徑為5 0 0≤的塑料埋地排水管道：如果盡可能選用環(huán)剛度≥8KN/，如果選擇小于8kN/的環(huán)剛度，則必須通過(guò)結(jié)構(gòu)規(guī)劃和核算，嚴(yán)格控制鋪設(shè)施工質(zhì)量。 </p> <p> 七是施工中要保證回填土質(zhì)量?；靥钔恋膲簩?shí)度應(yīng)符合以下規(guī)定：主管區(qū)回填土的壓實(shí)度不小于95%，超出管寬的二級(jí)管區(qū)回填土的壓實(shí)度不小于90%。 </p> <p> 然后，我們需要提醒大家，在選擇HDPE雙壁波紋管管道的環(huán)剛度之前，我們應(yīng)該對(duì)管道的所有方面進(jìn)行理解。只有對(duì)管道有了詳細(xì)的了解，才能根據(jù)實(shí)際情況作出更好的判斷。雙壁波紋管分PVC-U雙壁波絞管和HDPE雙壁波絞管。</p><div style="width:100%;text-align: center;"><img
