Application of Patent Technique for Ultra-light Well Site Dewatering in Foundation Pit Engineering

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.
