Is it necessary to deduct the volume of the pipeline from the measurement of concrete? Ensure that the concrete is 1m* 1m and the pipe diameter is 400. Do you want it in the calculation of concrete quantities? The volume occupied by the pipeline should be deducted,

It is better to buckle according to the outside diameter of the pipeline, and see what material it is according to DN400.

However, in practical engineering, if the amount of packaging is small when crossing the road section, this amount of concrete does not use external walls. Compared with the packaging quantity, the inner and outer wall errors are negligible! Just calculate it according to the standard pipe diameter ~
