问题: 帮忙翻译~~~~~~~~~~~~
由于管段F1-HOUSE B ,F1-HOUSE C和F1-HOUSE D都是Down pipe,所以没有做清洗及CCTV Survey.
人井F5内有积水,出水方向是Down pipe;人井F7井盖丢失,已经被废弃, 所以F5-F6,F6-F7,F7-OUTSIDE没有做清洗及CCTV Survey.
人井请用:Manhole.
解答:
The F1-HOUSE B ,F1-HOUSE C and F1-HOUSE D are not be cleared and CCTV Surveyed since they are Down pipe.
There are collected water in Manhole F5.The direction of water flowing is toward the Down pipe.The lid of Manhole F7 is lossed which was abandoned.So F5-F6,F6-F7,F7-OUTSIDE were not be cleared and CCTV surveyed.
