室內塑料排水管道安裝
1  范圍
      本工藝標準適用于民用及一般工業建筑室內生活排水、雨水及有酸堿性的排水管道安裝工程。
2  施工準備
    2.1  材料要求：
    2.1.1  管材為硬質聚氯乙烯（UPVC）。所用粘接劑應是同一廠家配套產品，應與衛生潔具連接相適宜，并有產品合格證及說明書。
    2.1.2  管材內外表層應光滑，無氣泡、裂紋，管壁薄厚均勻，色澤一致。直管段撓度不大于l%。管件造型應規矩、光滑，無毛刺。承口應有梢度，并與插口配套。
    2.1.3  其它材料：粘接劑、型鋼、圓鋼、卡件、螺栓、螺母、肥皂等。
    2.2  主要機具：
    2.2.1  手電鉆、沖擊鉆、手鋸、銑口器、鋼刮板、活扳手、手錘、水平尺、套絲板、毛刷、棉布、線墜等。
    2.3  作業條件：
    2.3.1  埋設管道，應措好槽溝，槽溝要平直，必須有坡度，溝底夯實。
    2.3.2  暗裝管道（包括設備層、豎井、吊頂內的管道）首先應核對各種管道的標高、坐標的排列有無矛盾。預留孔洞、預埋件已配合完成。土建模板已拆除，操作場地清理干凈，安裝高度超過3.5m應搭好架子。
    2.3.3  室內明裝管道要與結構進度相隔二層的條件下進行安裝。室內地平線應彈好，初裝修抹灰工程已完成。安裝場地無障礙物。
3  操作工藝

Indoor Plastic Pipeline Installation
1 Scope
      This technology is applicable to civil and general industrial indoor living water, rain and a pH of sewer installation.
2 construction preparation
    2.1 Material Requirements:
    2.1.1 for the rigid PVC pipe (UPVC). Should be used in adhesives manufacturers supporting the same product should be connected with appropriate sanitary ware, and a product certificate and manual.
    2.1.2 pipe outside surface should be smooth, no bubbles, cracks, wall Bo Hou, color and luster. Straight sections of deflection is less than l%. Tube shape should be rules, smooth, burr-free. Socket should shoot degrees, complete with socket.
    2.1.3 Other materials: adhesives, steel, round steel, card cases, bolts, nuts, soap.
    2.2 Main equipment:
    2.2.1 electric drill, impact drill, hand saw, milling mouthparts, steel scraper, live wrenches, hammers, spirit level, sets of silk board, brush, cloth, wire, etc. fall.
    2.3 Operating conditions:
    2.3.1 pipe laying, should be good measures trenches, grooves to straight, must have slope, ditch compaction.
    2.3.2 concealed pipes (including the equipment level, shaft, ceiling inside the pipes) should first check the level of various channels, whether the arrangement coordinates of contradictions. Reserved for holes, embedded parts have been completed with. Civil template has been removed, the operation site clean up, installation and setting up the shelf to be taller than 3.5m.
    2.3.3 Indoor out the progress of installation of pipelines and structures under conditions away from the second floor installation. Indoor horizon should be good shells, plaster decoration works have been completed early. Installation site of obstruction.
