安裝水泥排水管有怎樣的步驟

來源:www.kadinask.com         發布時間:2021-09-09 返回列表
  水泥排水管的主要功能是承擔雨水、污水和農田排灌的排水任務。很多客戶說不知道怎么安裝水泥排水管。以下是:的詳細概述。

  安裝水泥排水管的主要步驟是什么?

  1.在設置管路之前,根據給定控制點的中心線設計,更要注意該領域布局的中心線、平折點、縱向折點以及起點和終點的線性度。

  控制中心樁,起點和終點平面折疊點外的凹槽位置合適。用方向鍵控制樁組,用測量法確定樁數。

  2.建立臨時水準點:在管道工程中,經常需要增加臨時水準點。設置在穩定、防碰撞的地方,距離不超過30m。臨時水準點閉合誤差應符合規定標準。

  3.挖掘機以挖溝為主,人工清底為輔,人工挖溝連接雨水漏斗的管道和支管。開挖過程中,注意土質變化,對有坍塌跡象的地段采取支護和圍護。

  4.挖掘機挖掘至槽底標高約10cm。槽底土應預留,不得開挖。手動清洗罐體,仔細檢查罐體底部的泥土擾動情況,如有擾動應進行特殊處理。

  5.在溝兩側,距溝底1m處對稱設置標高樁,并在樁上釘等標高。開挖底部和澆筑前,重新測量管道中心線和標高樁的高度。

  此外,單側橋墩的高度不應超過2m,與溝槽邊緣的距離不應小于1m。為明確好基礎位置,相關部門在管線施工中應注意地下管線的保護。對于地下設施,需要注意一孔的開挖樣本,以證明位置和施工的準確性,并注意各種預埋管道,以確保安全。在實際施工過程中,應對裸 露的管道進行支撐和保護。
