Abstract (en)

The invention relates to a device for making it easier to extract a vertical shuttering. This apparatus comprises means for forming removably in the back (1b) of the shuttering (1) at least one vertical guide groove (8) open over its entire length in a direction opposite to the shuttering face (1a), and means forming a shuttering-removing tool having a guide part (11) capable of sliding vertically in said groove, whilst being retained in the groove, and lateral knives (9, 10) capable of scraping the lateral sides (3, 4) of the shuttering during sliding, the apparatus comprising means (12) for controlling the sliding of said tool. The invention is used particularly for the shutterings serving for making a trench wall in the ground. <IMAGE>
