如何选择塑料检查井井座?
How to choose plastic inspection wells?
1. 首先确定塑料井口径(井筒口径)
1. first determine the caliber of the 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, 1000 series of plastic inspection wells in the market. 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, the smaller the caliber of the tube. 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 inspection wells are well distributed and the mud type. Sewage wellstock must choose flow trough type; Rainwater wellstock under normal circumstances choose sediment type, or part of the selection of flow trough type (sediment wellstock generally not less than 50%), sediment wellstock sediment height of 30 cm.
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 specification of the plastic well according to the caliber of the nozzle.
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
If the plastic wellbore diameter is 630 and the nozzle is 300 HDPE bellows, the wellbore should be 630*300 series.
5. 根据承接管材数量及角度确认型号
5. confirm the number according to the quantity and angle of pipe.
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。
Plastic inspection wells in the same series are divided into: starting wellbore, 90 degree wellbore, through wellbore, three-way wellbore, four-way wellbore.
