The present invention relates to a well tube shoe and a sinking method using the same enabling a smooth sinking process of a well drainage method by minimizing a frictional force applied to the well tube shoe. The well tube shoe including an insertion port on the lower end is sunken into the ground when the top of the well tube shoe is pressed or hit. At least one film supply unit from which multiple films are taken out along the outer circumference of the lower end of the well tube shoe in case of the sinking process of the well tube shoe to reduce a frictional force between the outer circumference of the insertion port and strata is formed inside the insertion port. |
