检查井模具模具不存在固定尺寸的标准，而且各地区对于地下管道材质的使用也不同，比如水泥管和波纹管的不同点，就可以在检查井模具内径大小以及壁厚上出现区别了，因为管道大小配比的井体内径是不同的， 所以在模具制作上就体现了不同点了，而且对于高度的掌握大多是在1.8米以上的标准施工，所以很多预制厂需要准备调节端，比如20厘米高、30厘米高、50厘米高的，这样就可以满足不同高度井体的对接了。
There is no fixed size standard for the inspection well mold, and the use of underground pipeline materials is different in different regions. For example, the different points of cement pipes and corrugated pipes can make a difference in the inner diameter and wall thickness of the inspection well mold. Because the inner diameter of the well body is different in the pipe size ratio, different points are reflected in the mold production, Moreover, the height is mostly controlled by the standard construction above 1.8m, so many prefabrication plants need to prepare adjustment ends, such as 20cm high, 30cm high and 50cm high, so as to meet the docking of wells with different heights.
