增強聚丙烯FRPP管件管道是如何進行鋪設的?

FRPP管(玻纖增強聚丙烯管)用經偶聯劑處理的玻璃纖維改性聚丙烯材料生產,依據HG20539-92標準,規格DN15-DN1500mm,公稱壓力0.4-1.0MPa,耐腐蝕、耐高溫、耐高壓、衛生無毒,可回收利用,適用于腐蝕性液體輸送(如酸堿液)及市政給排水系統。具有較優良的抗沖擊性和拉伸強度,重量輕,安裝維修方便,被廣泛應用于化工、化纖、氯堿、染料、給排水、食品、醫藥、污水處理、電解等行業。

FRPP管件基礎鋪墊:

此工程設計中要求采用墊層基礎。一般土質的地段,基底只需鋪一層厚度為0. 1 m的砂墊層即可;若為軟土地基,槽底高程又在PPH管材地下水位以下時,宜先鋪墊一層厚度≥0. 15 m的砂礫或碎石(碎石粒徑為5~40mm),再鋪砂墊層(中、粗砂),厚度≥0. 05m。

要將基礎表面整平并夯實?;A在道接口處應預留凹槽,以便完成接口后立即填實。

FRPP管道鋪設:

由人工搬運管節,搬運時須輕抬、輕放,嚴禁在地面上拖拉。

可采用人工下增強聚丙烯FRPP管材或起重機下管兩種方法。由人工下管時,可由位于地面的人員將管道傳遞給位于溝槽底的人員,也可用非金屬繩索系住管身兩端,將其緩慢溜放至溝槽內(注意保持管身平衡),嚴禁將管道由槽邊翻滾人槽內。采用起重機下管時,可用非金屬繩索系住管身緩慢放至槽內,嚴禁串心吊裝。

應將FRPP道的插口順水流方向、承口逆水流方向安裝,一般先安裝下游的PVDF管道,而后向上游推進。橡膠圈應放在管道的插口槽內。

接口時,先將承口的內壁清理干凈,并在承口內壁及插口橡膠圈上涂潤滑劑(選硅油),再將兩端的中心軸線對齊。接口方法與鋼筋混凝土管的接口方法相同。

為防止接口合攏時已鋪設管道的軸線偏移,需采取穩管措施。即在編織袋內灌滿黃砂并封口,將其壓在已鋪設PP-FRP管材管道的頂部,編織袋的數量視管徑大小而異。管道接口后應復核其高程和軸線。
