Research on tube well dewatering of inclined shaft excavating across water-bearing quicksand stratum
YU Xin-feng
Abstract：In order to ensure the smooth construction the inclined shaft pass through the water-bearing quicksand stratum, according to the dewatering mechanism, through theoretical calculation and analysis, a reasonable flow, well depth and layout are determined. The tube well dewatering is adopted to improve the stability of the surrounding rock by reducing the water level of local aquifer and strengthening the temporary support, so that the soil is consolidated, to prevent the working face collapse, roof caving accident, which lays the foundation for rapid and safe construction of the inclined shaft, and provides the reference for the construction of the wellbore under similar conditions.
