检查井接管安装
Inspection well connecting pipe installation
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，并逐渐向下游支管，干管延伸。
1. The sequence of connection and installation of manhole base and pipeline shall start from the upstream section of the connecting pipe, and be installed in the sequence of well pipe well pipe, and gradually extend to the downstream branch pipe and main pipe.
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 well seat joint and pipeline connection shall be consistent with that 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 of well seat and inlet pipe and discharge pipe needs to be changed. When reducing joint is used, when the inlet pipe diameter is smaller than the well seat interface pipe diameter, the top of the pipe shall be flat connected; when the well seat outlet pipe interface is larger than the downstream pipe, the bottom of the pipe shall be flat connected.
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 the pipe adopts variable angle joint or spherical joint to adjust the slope, when the pipe diameter is 315mm, special tools shall be used instead of chain spanner.
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. For the installation of additional joints, special tools shall be used to open holes on the shaft wall according to the shaft size and the diameter of connecting pipes. The peripheral edge of holes shall be flat, and the installation of additional joints shall not be sloped.
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 pipeline (including inspection well) is installed (but the irrigation test has not been carried out), the technical measures to prevent the well from floating up shall be taken.
