 1．   施工前準備
    1.1   熟悉設計圖紙和圖紙會審時的意見，了解特殊地點的施工要求。
    1.2   對進場材料進行清理、檢驗，必須符合設計要求，證件齊全。
    1.3   施工機具齊全、完好。
  2．   操作工藝要點
    2.1   層間垂直預留洞口，要按總高度統一掛線測量，層內水平預留洞口要按排水坡度進行檢測，對錯位孔洞要補鑿、矯正。穿墻、穿層管道要按有關規定埋設保護套管。屋面套管必須用金屬管，其直徑要比所用管道大2級，超出屋面高度不小于100mm。
    2.2   管道安裝，特別是室內外立管，應掛線校正，立管與墻的距離一般為30mm。塑料管接口要干凈，刷膠均勻，插入深度足夠。立管與各層橫管的接口要注意方向和標高，立管的彎頭要用45度彎頭組成。
    2.3   排水立管每層設置伸縮節一個，若層高大于5米則應設置2個，伸縮節應設在靠近水流匯合配件伸縮量大的一側。在污水立管上應設置檢查口，在最底層和有衛生器具的最高層必須設置。暗裝立管檢查口要裝檢修門。
    2.4   固定塑料排水管的支架貼合應為柔性；支點距離立管直
1. Pre-Construction
    1.1 familiar with the design drawings and drawings reviewing the views of the time to understand the special place of construction requirements.
    1.2 approach to clean up materials, inspection, must meet the design requirements and complete documents.
    1.3 Construction machinery complete, intact.
  2. Operation process elements
    Set aside 2.1 layer vertical hole, according to the total height measurement of uniform hung, horizontal layers according to the drainage slope of the hole reserved for detection of misplaced holes to make up the hammer and correction. Through walls, through pipes in accordance with the relevant provisions of the buried layer of protection sleeve. Roof must be metal pipe casing, the diameter of the pipe than the big two, beyond the roof height of not less than 100mm.
    2.2 The pipeline installation, particularly in indoor and outdoor riser, should be hung correction, the distance between vertical and wall usually 30mm. Plastic tube interface is clean, gluing uniform insertion depth enough. Between vertical and horizontal control interface layers to pay attention to the direction and elevation, riser elbow 45 degrees elbow to use composition.
    2.3 The expansion joints on each floor drain of a riser, if the story should be set greater than 5 m 2, expansion joints should be located near the water side of the confluence of large flexible parts. Riser in the water should be set up checkpoints at the bottom and the highest level of health equipment must be set. Concealed riser inspection port to install access door.
    2.4 fixed plastic drainage stents should be flexible fit; pivot riser straight away
