4. The thickness of concrete wall at the pipe penetration shall not be less than 300, otherwise the wall shall be thickened on one side or both sides, and the diameter of the thickened part shall be at least D5+200.



5. The weight of casing shall be calculated as L=300. If the wall thickness is greater than 300, it shall be calculated separately.
