民居雨·污水该如何规范布管

排水布管预埋乱成一团，请高手们指点一二，不吝赐教！4层民居，底层管道井在半边墙内，2层开始拐出墙外，因为考虑管井穿断了半边梁。（做明管井日后用防潮板包起）还是全部走墙外好，具体怎样做否符合规范？谢谢！ [localimg=600,450]6[/localimg][localimg=600,450]3[/localimg][localimg=600,450]4[/localimg][localimg=600,450]5[/localimg][localimg=600,450]6[/localimg][localimg=320,240]10[/localimg][localimg=600,450]12[/localimg][localimg=600,450]18[/localimg][localimg=600,450]20[/localimg][localimg=600,450]21[/localimg][localimg=320,240]1[/localimg][localimg=600,450]6[/localimg][localimg=600,450]7[/localimg][localimg=600,450]8[/localimg][localimg=320,240]11[/localimg][localimg=600,450]17[/localimg][localimg=320,240]14[/localimg][localimg=320,240]15[/localimg][localimg=600,450]16[/localimg][localimg=600,450]13[/localimg]
