How to choose the plastic check well seat?

1. 首先确定塑料井口径（井筒口径）

1. first determine the caliber of plastic well (bore diameter)

目前市场上塑料检查井口径主要有315、450、630、700、1000系列（单位毫米）。图纸一般会明确使用哪个口径的检查井。如没有明确说明需要和业主确认好具体规格。口径越小，承接管材口径也越小。例如315系列承接管材口径最大为300管材。

At present, there are 315, 450, 630, 700 and 1000 series of caliber of plastic inspection wells in the market (unit mm). Which caliber inspection well is usually used in the drawing. If it is not clearly stated, the specific specifications need to be confirmed with the owner. The smaller the caliber is, the smaller the caliber is. For example, the 315 series has a maximum diameter of 300 pipes.

2. 确认塑料检查井使用部位（雨水/污水）

2. confirm the use area of plastic inspection wells (rainwater / sewage).

塑料检查井井座分流槽式和沉泥式。污水井座必须选用流槽式;雨水井座常规情况下选用沉泥式，或部分选用流槽式（沉泥井座一般不低于50%），沉泥式井座沉泥式高度为30cm。

The plastic check well seat distributary slot type and slime type. The sewage well base must choose the type of slots; in the case of the rain and water well, the slime type is selected, or the tank type is selected (the slime well is generally not less than 50%), and the sinking mud type height of the slime base is 30cm.

3. 确认塑料检查井井座内径井座/外径井座

3. confirm the inside hole of the plastic inspection well location.

塑料检查井座根据使用管材不同分内径井座、外径井座。

The plastic inspection well block is divided into inner diameter well block and outer diameter well block according to different pipe materials.

4. 根据接管口径确认塑料井具体规格

4. confirm the specific specification of plastic well according to the diameter of the pipe

如塑料井井筒口径为630，接管为300HDPE波纹管，井座应该选用630*300系列

For example, the bore diameter of the plastic well is 630, the nozzle is 300HDPE bellows, and the well block should be 630*300 series.

5. 根据承接管材数量及角度确认型号

5. confirm the model according to the quantity and angle of accepting pipe material

塑料检查井同一系列分为：起始井座、九十度井座、直通井座、三通井座、四通井座。
