室内塑料排水管道安装
1  范围
      本工艺标准适用于民用及一般工业建筑室内生活排水、雨水及有酸碱性的排水管道安装工程。
2  施工准备
    2.1  材料要求：
    2.1.1  管材为硬质聚氯乙烯（UPVC）。所用粘接剂应是同一厂家配套产品，应与卫生洁具连接相适宜，并有产品合格证及说明书。
    2.1.2  管材内外表层应光滑，无气泡、裂纹，管壁薄厚均匀，色泽一致。直管段挠度不大于l%。管件造型应规矩、光滑，无毛刺。承口应有梢度，并与插口配套。
    2.1.3  其它材料：粘接剂、型钢、圆钢、卡件、螺栓、螺母、肥皂等。
    2.2  主要机具：
    2.2.1  手电钻、冲击钻、手锯、铣口器、钢刮板、活扳手、手锤、水平尺、套丝板、毛刷、棉布、线坠等。
    2.3  作业条件：
    2.3.1  埋设管道，应措好槽沟，槽沟要平直，必须有坡度，沟底夯实。
    2.3.2  暗装管道（包括设备层、竖井、吊顶内的管道）首先应核对各种管道的标高、坐标的排列有无矛盾。预留孔洞、预埋件已配合完成。土建模板已拆除，操作场地清理干净，安装高度超过3.5m应搭好架子。
    2.3.3  室内明装管道要与结构进度相隔二层的条件下进行安装。室内地平线应弹好，初装修抹灰工程已完成。安装场地无障碍物。

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.
