| 1、检查井井座与管道连接安装顺序，应先从接户管上游段开始安装，以井-管-井-管顺序安装，病逐渐向下游支管，干管延伸。 1. Inspection wellbore and pipeline connection installation sequence, should start from the upstream section of the nozzle installation, to the well-pipe-well-pipe installation sequence, disease gradually downstream branch pipe, trunk pipe extension. 2、井座接头与管道连接施工方法，应与同类型接头的管道连接的施工方法一致。 2. The construction method of wellbore joint and pipeline connection should be consistent with the construction method of pipeline connection of the same type of joint. 3、井座与汇入管，排出管连接需要变径，采用异径接头时，当汇入管径小于井座接口管径时，应管顶平接；井座排出管接口大于下游管道时，应管内底平接。 3. The connection between wellbore and inlet pipe needs to be changed in diameter. When the diameter of inlet pipe is smaller than the diameter of wellbore joint, the top of the pipe should be flat. When the outlet pipe of wellbore is larger than the downstream pipe, the bottom of the pipe should be flat. 4、管道采用可变角接头或球形接头调整坡度时，当其管径为315mm,应采用专用工具，不得使用链条扳手。 4. When adjusting the gradient of pipeline with variable angle joint or spherical joint, when the diameter of pipeline is 315 mm, special tools should be used instead of chain wrenches. 5、附加接头的安装，应根据井筒尺寸和连接管道的直径，采用专用工具在井壁上开孔，孔洞圆周边缘应平整，安装附加接头不得倒坡。 5. The installation of additional joints should be based on the size of wellbore and the diameter of connecting pipes. Special tools should be used to open holes in the wellbore. The circumferential edge of the holes should be smooth, and the installation of additional joints should not reverse the slope. 6、在地下水位较高或雨季施工期间，在管道（含检查井）安装完成（但尚未进行灌水试验）时，应采取防止井体上浮的技术措施。 6. During the construction period of high groundwater level or rainy season, when the installation of pipeline (including inspection wells) is completed (but no irrigation test has been carried out), technical measures should be taken to prevent the wellbore from floating. |
