The present invention relates to a steel pipe press-fitting method to detect a deformation of a steel pipe through calculation by deformation rate calculation sensors, and more specifically, relates to a steel pipe press-fitting method to detect a deformation of a steel pipe through calculation by deformation rate calculation sensors, wherein a deformation rate of the steel pipe is measured with the deformation rate calculation sensors installed on an interior of the steel pipe pressed and fitted to a ground, a deformation of the steel pipe is detected based on a measured deformation rate, and a linearity of the steep pipe is improved by correcting the deformation of the steep pipe by heating the steel pipe. The steel pipe press-fitting method to detect a deformation of a steel pipe through calculation by deformation rate calculation sensors comprises: a deformation rate calculation sensor installation step of installing a plurality of deformation rate calculation sensors on a position of an inner circumferential surface of the steel pipe pressed and fitted to the ground in a circumferential direction, the position being away from a front end part of the steel pipe at a predetermined distance; a heating means installation step of installing a plurality of heating means on a position of the inner circumferential surface of the steel pipe in the circumferential direction to apply heat to the steel pipe, the position being away from the deformation rate calculation sensors at a predetermined distance; a press-fitting step of pressing and fitting the steel pipe where the deformation rate calculation sensors and the heating means are installed to the ground; a calculation step of calculating a deformation rate of the steel pipe with the deformation rate calculation sensors measured in the press-fitting step; and a deformation estimation step of estimating whether the steel pipe is deformed based on the deformation rate measured in the calculation step. |
