a、在特别路段无法满意上述埋深要求时，当采用塑料管敷设时，若管道顶至地面距离大于0.3m时，采用混凝土水泥(C15)包封，包封厚度15～20cm 。若管道顶至地面距离在小于0.3m时，必须采用无缝镀锌钢管保护。对于共建或合建的PVC管道群在特别路段，管道群最上层管孔的顶层距地面小于0.15m而又无法使用钢管保护的应采用包。
b、封厚度大于30cm的水泥混凝土包封。
c、进入人（手）孔处的管道底部距人（手）孔底板面及管道顶部。
d、距人（手）孔内上覆顶面（即人孔内上覆面）的净距不得小于0.3M 。若特别情况，以现场签证为准。
e、管道坡度应有一定的坡度，可为3‰~4‰，不得小于2.5‰，不得有向上弯曲的管道管孔：无损坏、无阻塞、无淤泥、无杂物。
