How to install the plastic inspection well?

塑料检查井井盖松动破损的现象一部分原因是塑料检查井的安装不够规范，下面是塑料查井安装的几个要点：

Part of the reason for the loosening and damage of the plastic inspection well cover is that the installation of the plastic inspection well is not standardized. The following are the main points of the plastic inspection well cover installation:

1.检查井井座与管道连接安装顺序：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. Check the sequence of wellbore and pipeline connection and installation: first start from the upper part of the connecting pipe, install in the order of well-pipe-well-pipe, and gradually extend downstream branch pipe, trunk pipe.

2.井座接头与管道连接：与同类型接头的管道连接施工方法一致。

2. connection between well seat and pipe: same as the connection of the same type of joints.

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，应采用管顶平接；井座排出管接口大于下游管道时，应管底平接。

3. Connection between wellbore and inlet pipe and outlet pipe needs to be changed in diameter: when the inlet pipe diameter is less than the wellbore joint diameter, the top of the pipe should be connected horizontally; when the wellbore outlet pipe interface is larger than the downstream pipe, the bottom of the pipe should be connected horizontally.

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,不得采用链条扳手。

4. When adjusting the gradient with variable angle joint or spherical joint, the chain wrench should not be used when the pipe diameter is 315mm.

5.附加接头的安装：应根据精通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破。

5. Installation of additional joints: According to the proficient size and the diameter of the connecting pipe, special tools should be used to open holes in the shaft wall, hole circumferential edge should be smooth, installation of additional joints should not break.

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（但尚未进行灌水实验时），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, technical measures should be taken to prevent the wellbore from floating when the pipeline (including inspection wells) is installed (but no irrigation experiment has been carried out).
