鋼筋混凝土排水管的鋪設要求講解

來源:www.kadinask.com         發布時間:2021-09-23 返回列表
  鋼筋混凝土排水管的鋪設要求如下:排水管開槽至設計標高后,與有關方面進行開槽檢查后進行基礎澆筑。所需經費如下:

  1.澆筑混凝土平底樁后,澆筑上部管道基礎時,要特別注意管下混凝土的密實度。

  2.管道基礎應落在有一定承載力的原狀土層上,否則應對基礎進行處理。

  3.應采取施工措施防止管道基礎混凝土產生裂縫。

  4.混凝土基礎的側模應具有一定的強度和剛度。模板安裝應留有緊密間隙,支撐牢固并滿足結構尺寸要求。

  5.只有當抗壓強度大于5.0N/mm2時,才能安裝平底混凝土。

  6.檢查排水溝和土基是否符合要求,用扁樁的外露長度檢查扁基礎的厚度是否符合要求。超過允許誤差時,應重新清理底部,超大基坑應進行砂墊層處理。

  7.你應該熟悉平底的設計厚度,這樣你就可以確定模板的高度和模板之間的凈寬度。

  8.混凝土入模后,按平樁找平,插搗密實。當厚度大于20厘米時,用平面振動器振動壓實。

  9.管道應按圖紙要求進行閉水試驗和竣工驗收。

  10.管道必須有出廠合格證。進入現場后,應對管道進行目視檢查(裂縫、缺陷、凹陷表面等)。)從管道中排出之前。用水泥砂漿帶擦拭噴嘴。

  在鋪設鋼筋混凝土排水管之前,應重新檢查承口的外觀和尺寸,并征得工程師同意后才能進行施工。鋪設鋼筋混凝土排水管時,鋪設前必須檢查插座的外觀和尺寸,征得工程師同意后方可施工。
