采用HDPE材料系工程塑料生產(chǎn)的梅花管，應(yīng)用范圍十分大范圍，由于本身的蜂窩形狀形成的結(jié)構(gòu)強(qiáng)度高，還有特點(diǎn)是耐低溫性強(qiáng)，尤其適合我國北方地下管道工程。該種材料因其本身特性決定，韌性好，有較理想的彎曲度，其老化程度較高，其使用年限具檢測部門檢驗(yàn)在五十年以上，并具有較強(qiáng)的抗腐蝕性，不受低溫情況下作業(yè)的影響，使用溫度在-40℃—80℃。其脆化溫度可達(dá)-70℃，吸水率小于(而聚氯乙烯脆化溫度*-30℃，吸水率—)。HDPE管材鋼韌并存的特點(diǎn)，適用于北方冬季地面，凍層起伏不一致而不易折斷。施工時(shí)可隨管溝型而彎曲，彎曲直徑可達(dá)10米，保證內(nèi)部結(jié)構(gòu)不變形、不斷裂。這樣就可以躲過在施工時(shí)所遇的障礙。產(chǎn)品所需原材料主要是采用高密度聚乙烯(HDPE)，該產(chǎn)品具有抗壓、耐沖擊、撓性和低溫回彈性。在熱帶和寒冷地帶均可使用。外型新穎美觀，受力均勻，接頭采用防水膠卷。七孔管的單孔內(nèi)徑為ф32mm(±)，整體外徑ф108mm(±)；產(chǎn)品長度按需要確定，但不超過8M。五孔管單孔內(nèi)徑為ф32mm，整體外徑ф86mm，可以直接鋪埋于地下，無需外保護(hù)措施，但底面要平整鋪實(shí)。性能特點(diǎn)：直埋梅花管系列適民用航空于光纜，電纜和穿導(dǎo)、隔離及保護(hù)。</p><p> 產(chǎn)品具有防水、防潮、抗老化、使用壽命長、耐侯好的特點(diǎn)，同時(shí)由于它是一次性成型的一體化多孔護(hù)套管，所以施工方便，增加了預(yù)埋孔數(shù)，提高了施工速度，較大降低了工程單位的材料及施工成本。如何安裝梅花管以及注意事項(xiàng)！（1）管道的埋設(shè)地溝應(yīng)按設(shè)計(jì)要求和施工操作盡可能平直，如溝底不平可鋪上一層細(xì)沙。埋管前應(yīng)清理溝內(nèi)的硬質(zhì)物，防止管道變形。開始埋管時(shí)，應(yīng)將多孔管預(yù)留10-15CM在人井，以便穿纜。應(yīng)將管堵塞住露在人井端的子管。埋管時(shí)嚴(yán)禁泥沙異物混入管內(nèi)。（2）多孔梅花管管道連接將管材狀定位筋朝上放置，將端部管材外壁清理干凈，再將直接一端承口插入，再端面上墊上一塊厚木板，用錘頭敲打板，使管材承插到位。在直接的另一端承接口處，將另一根管材插入直接并承插到位，如此順延至下一個(gè)人井處。在實(shí)際施工中，每根管材的長度連起來不一定和人井之間的長度一樣，在這種情況下，根據(jù)實(shí)際的人井的長度，距離量好管材的長度，并用鋼鋸鋸斷，一定要鋸平整齊。對接完成之后，伸入人井的一端要求用管塞塞好，防止異物侵入。（3）初次安裝使用本產(chǎn)品者，可在鋪設(shè)首段〈兩個(gè)人井之間的距離時(shí)〉先不要回填土。用穿纜器試穿一孔或兩孔，順利穿入后，再往下段鋪設(shè)。6、使管材具有一定的撓度，能輕松越過障礙物。</p><div
