The invention discloses a borehole wall protection plugging or inclined deflecting drilling method and a PVC material containing pipe device used for drilling. The method comprises the following steps: preparation of PVC material containing pipe device; the material holding device into PVC tube drilling target position through the drill pipe; drill hole by hole in local mixing and stirring, crushing the material containing PVC tube, the tube material containing mixed fully in the target position and extrusion, cementation synthesis overall, the formation of artificial hole wall in a short period of time, or the rapid formation of artificial hole, and the rock bottom. The PVC material pipe device used at least comprises a PVC material tube and an agitating drill bit in the hole, and the PVC material tube is hung in the hole through the hanging ring arranged at the upper end of the drill tube to stir the lower end of the drill bit. The method and the device provided by the invention enable accurate positioning of the drilling hole when the hole is lowered, the loss of the setting time is controllable, the strength of the consolidation body is controllable, and the utility model has the advantages of economy, effectiveness and good operability.
