What the drawing shows
Typical brick manhole at a UTX / under-road / farm crossing: plan and sections, duct entry, cover, soakaway, and the set-back from the sleeper end.
Typical drawings are a starting point: the project design, the site survey and the current standards decide what is actually built.
