1. Process for the withdrawal of a shuttering element (3) used in making a panel (P) of a wall moulded in the ground, said shuttering element comprising a shaped central portion whose outline corresponds to the pattern to be imparted to the end of the panel to be made, and two wings (4) extending on both sides of said central portion, characterized by the following steps : - providing such a shuttering element (3) which protrudes above the ground surface ; - fitting on the protruding portion of said shuttering element an implement comprising a body (1) and two shaped parts (2) forming side grooves which are slidable upon the wings of said shuttering element, the lower portion (6) of said shaped parts being bevelled so as to form a dismantling wedge ; - imparting a beating motion to the implement so as to force the wedge-shaped parts between the concreted panel and its shuttering element until their introduction therebetween ; and - pursuing said beating motion so as to drive the implement deeper and deeper until complete release of the shuttering element.
