Installation of pipes and wellbore for plastic inspection wells in Dao Feng

塑料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，并慢慢向下游支管，干管延伸。

Plastic inspection wellbore and pipeline connection installation sequence, should start from the upper part of the connecting pipe installation, to the wellbore-tube-well-tube sequence installation, and slowly downstream branch pipe, trunk pipe extension.

塑料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。塑料井座与汇入管，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；井座排出管口大小于下游管道时，应管内底平接。管道采用可变角接头或球形接头调整坡度时，当其管径大于315MM，应采用专用工具，不得使用链条扳手。

The construction method of plastic wellbore joint and pipeline connection should be the same as that of pipeline connection of the same type of joint. The connection between the plastic wellbore and the inlet pipe and the discharge pipe needs to be changed in diameter. When the inlet pipe diameter is less than the wellbore joint pipe diameter, the top of the pipe should be connected horizontally; when the wellbore outlet pipe size is smaller than the downstream pipe, the bottom of the pipe should be connected horizontally. When the pipeline adopts variable angle joint or spherical joint to adjust the gradient, when the pipe diameter is greater than 315MM, special tools should be used and chain wrench should not be used.

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。如倒坡很容易造成积水现象。在地下水位较高或雨季施工期间，在管道安装完成时，应采取防止塑料井上浮的技术措施。

Additional joints should be installed in accordance with the wellbore size and the diameter of the connecting pipe, the use of special tools in the wellbore hole, hole circumferential edge should be flat, the installation of additional joints can not slope. If the slope falls, it is easy to cause stagnant water. During the construction period of high groundwater level or rainy season, technical measures should be taken to prevent the floating of plastic wells when the pipeline is installed.

然后将PE中空缠绕井筒一头套上井筒胶圈，套井筒皮圈的时候注意不要套反了，要让胶圈的裙边贴在井筒的底部，在井座的井筒承口内侧及井筒胶圈上抹上白猫洗洁精，在承插井筒的时候要左右前后晃动，这样就容易承插，一定要让井筒底部插到井筒承口的底部，这样密封效果才更好。

Then the PE hollow winding wellbore one end sleeve wellbore rubber ring, sleeve wellbore skin ring when pay attention not to the reverse sleeve, to let the Apron Skirt stick to the bottom of the wellbore, in the wellbore wellbore bearing inside and wellbore rubber ring on the white cat cleanser, in the wellbore bearing wellbore before and after shaking, so it is easy to plug, must be The bottom of the wellbore is inserted into the bottom of the wellbore so that the sealing effect is better.
