 1．   施工前准备
    1.1   熟悉设计图纸和图纸会审时的意见，了解特殊地点的施工要求。
    1.2   对进场材料进行清理、检验，必须符合设计要求，证件齐全。
    1.3   施工机具齐全、完好。
  2．   操作工艺要点
    2.1   层间垂直预留洞口，要按总高度统一挂线测量，层内水平预留洞口要按排水坡度进行检测，对错位孔洞要补凿、矫正。穿墙、穿层管道要按有关规定埋设保护套管。屋面套管必须用金属管，其直径要比所用管道大2级，超出屋面高度不小于100mm。
    2.2   管道安装，特别是室内外立管，应挂线校正，立管与墙的距离一般为30mm。塑料管接口要干净，刷胶均匀，插入深度足够。立管与各层横管的接口要注意方向和标高，立管的弯头要用45度弯头组成。
    2.3   排水立管每层设置伸缩节一个，若层高大于5米则应设置2个，伸缩节应设在靠近水流汇合配件伸缩量大的一侧。在污水立管上应设置检查口，在最底层和有卫生器具的最高层必须设置。暗装立管检查口要装检修门。
    2.4   固定塑料排水管的支架贴合应为柔性；支点距离立管直
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
