| Abstract: | Many practical difficulties were solved by the patent technique for ultra-light well site dewatering in these years,which was applied in a foundation pit engineering to remedy insufficient dewatering of tube well.In local quicksand layer,well tube was obliquely and quasi-horizontally set to realize dewatering and ensure the construction of excavation with compound soil nail support. |
| Keywords: | ultra-light well site dewatering foundation pit |
