TRACING METHOD FOR THE CONSTRUCTION OF A BASIN AND JIG FOR IMPLEMENTING SAID TRACING METHOD

摘要

The present invention relates to a method of ground tracing (S) for the construction of a basin, in which the contour of the basin (1) is drawn by means of a template. A template is used whose contour corresponds substantially to the contour of said basin (1) and has first and second openings arranged to form a first and a second reference point (P1, P2), said openings being arranged at a location predetermined on the surface of said template, is deposited on the ground (S) said template in a selected orientation, is marked on the ground (S) the outline of the basin (1) along the outline of the template by means of a tracer (4), said first and second reference points (P1, P2) are marked on the ground (S) through said first and second openings by means of a tracer, the template is removed, and the said first and second reference points (P1, P2) and at least two predefined lengths are used to determine the position of at least one auxiliary element with respect to the basin contour (1), and the ground mark is marked on the ground. location of said auxiliary element on the basin contour (1).
